Description

Technical Field

[0001] This application relates to the field of communication technology, and in particular to a sensing method and apparatus. Background Technology

[0002] Communication-sensing integration combines wireless communication and sensing functions into a single system. It utilizes the various propagation characteristics of wireless signals to achieve sensing functions such as target localization, detection, imaging, and identification, thereby acquiring information about the surrounding physical environment, improving communication performance, and enhancing user experience. In communication-sensing integration technology, sensing signals can be used to obtain information such as the position and velocity of targets in the environment.

[0003] Currently, there is no resource allocation technology for sensing systems, and how to allocate resources in sensing systems has become an urgent problem to be solved. Summary of the Invention

[0004] This application provides a sensing method and apparatus for providing a configuration method for sensing resources.

[0005] Firstly, this application provides a sensing method. The executing entity of the method is a first device, which can be a first equipment, or a chip or circuit on the first equipment side. The first equipment can be a network device or a terminal device. The method includes: receiving first information, the first information being used to configure a first set of sensing resources, the first set of sensing resources including periodically repeating first sensing resources; and transmitting a first sensing signal on the first sensing resources, the first sensing signal being used to determine information about a sensing target.

[0006] This application provides a unified configuration method for the set of sensing resources, thereby allowing different sensing transmitters (e.g., a first device and a second device) to transmit sensing signals on the same sensing resources, which can reduce the resource overhead of sensing at the system level.

[0007] Furthermore, since sensing can be continuous, the periodically repetitive sensing resources in this application allow the sensing transmitter and receiver to accumulate sensing signals, thereby improving the accuracy of information for determining the sensing target.

[0008] In one possible design, transmitting a first sensing signal on a first sensing resource includes: transmitting the first sensing signal on each first sensing resource included in the first set of sensing resources; and / or, transmitting the first sensing signal on each first sensing resource included within a first time period, the first time period being the accumulation duration of the first sensing signal; and / or, transmitting the first sensing signal on each first sensing resource included in at least one period of a periodically repeating set of first sensing resources. It can be understood that the first time period is the time period for the accumulation of the sensing signal, for example, the first time period is the time period for the accumulation of the first sensing signal.

[0009] By constraining the transmission of sensing signals on each sensing resource in the sensing resource set, the impact of a sudden cessation of sensing signal transmission by the sensing device on sensing accuracy can be reduced. For example, if the sensing device does not transmit sensing signals on the last few sensing resources in the sensing resource set, a sudden change in the sensing signal can easily be misinterpreted as motion of the sensing target. Similarly, if the sensing device only begins transmitting sensing signals on a non-first sensing resource in the sensing resource set, a sudden change in the sensing signal can also easily be misinterpreted as motion of the sensing target. This application, by constraining the transmission of sensing signals on each sensing resource in the sensing resource set, avoids the impact of sudden cessation of sensing signals on sensing services and improves sensing accuracy. Based on the above design, either the first device (and / or the second device) transmits sensing signals on all sensing resources in the sensing resource set, or the first device (and / or the second device) does not transmit sensing signals on any sensing resources in the sensing resource set. This minimizes the possibility of sudden changes in the amplitude and / or phase of signals received on multiple first resources within the sensing resource set, thereby reducing the impact on sensing accuracy.

[0010] In one possible design, during the second time period, the transmission power of the first device transmitting the first sensing signal on the first sensing resource remains constant; or, during the second time period, the change in the transmission power of the first device transmitting the first sensing signal on the first sensing resource is the same as the change in the transmission power of the second device transmitting the second sensing signal on the first sensing resource.

[0011] By constraining the transmission power of the sensing signal to remain constant or change in the same way, the impact of power variations in the transmitted sensing signal can be avoided. For example, if the second device stops / starts transmitting the sensing signal midway through the first time period Tw of the first device, it will cause a sudden change in the sensing signal on the first sensing resource, which can easily be misinterpreted as the movement of the sensing target. However, by constraining the transmission power of the sensing signal to remain constant or change in the same way, the impact of power variations in the sensing signal on the sensing service can be avoided, thus improving the accuracy of sensing. Based on the above design, either the first device (and / or the second device) transmits the sensing signal at the same transmission power on all sensing resources within the sensing resource set, or the first device (and / or the second device) does not transmit the sensing signal on any of the sensing resources within the sensing resource set. This can minimize the impact on sensing accuracy by avoiding sudden changes in the amplitude and / or phase of the received signal on multiple first resources within the sensing resource set. Alternatively, if the power of the first device's transmitted sensing signal changes, the fourth device can compensate for the impact of the power change on the amplitude change of the received signal, thereby obtaining the portion of the change in the received sensing signal caused by the target movement, and thus reducing the impact on sensing accuracy.

[0012] In one possible design, a third piece of information is transmitted, which indicates a change in the transmission power of the sensing signal transmitted on the first sensing resource. This design allows for identical changes in the transmission power of sensing signals transmitted by different devices.

[0013] In one possible design, the second time period is the temporal resource of the first set of sensing resources. This design allows for controllable power of the transmitted sensing signals within the first set of sensing resources; consequently, the only influencing factor on changes in the received sensing signals is the motion of the sensing target.

[0014] In one possible design, the first set of sensing resources is periodically repeated. This design increases the accumulation time of the sensing signal, thereby improving the accuracy of the sensing.

[0015] In one possible design, the first information is used to configure a first set of sensing resources for the first and second devices. This allows multiple devices to transmit sensing signals on the same sensing resources, thereby increasing the dynamic components of the sensing signals and improving sensing accuracy.

[0016] In one possible design, the period of the first set of sensing resources is A1 times the first time period, or the first time period is B1 times the period of the first set of sensing resources, where the first time period is the accumulation duration of the first sensing signal, and A1 and B1 are both positive integers.

[0017] In one possible design, the period of the first set of sensing resources is C times the period of the first set of sensing resources. a times, of which C a It is a positive integer.

[0018] In one possible design, the first set of sensing resources includes D in the frequency domain. a Each frequency domain unit, the first sensing resource includes E in the frequency domain. a There are E frequency domain units, of which E frequency domain units are in D a Each frequency domain cell is evenly spaced, or, E a Each frequency domain unit is D a One frequency domain unit; D a E is an integer greater than 0. a It is greater than 0 and not greater than D. a Integers.

[0019] In one possible design, the temporal resources of the first set of sensory resources originate from temporal unit t. a Beginning; t a Satisfy: t a mod(P1 a ) = G a Among them, G a The value of the first parameter corresponding to the first set of sensing resources is P1. The first parameter indicates the starting time-domain unit of the sensing resource set, or, the first parameter indicates the starting time-domain unit of each period of the sensing resource set. a For the period of the first set of sensory resources, or, P1 a The number of temporal units included in the period of the first set of sensing resources. This allows for the configuration of a parameter G. a This indicates the first set of sensing resources for the cycle, i.e., the starting time-domain unit of each cycle, reducing signaling overhead. The first and second sets of sensing resources correspond to different values ​​of the first parameter G. a and G a In other words, the first set of sensing resources and the second set of sensing resources for each period can be indicated in a unified way, that is, the starting time domain unit of each period of the first set of sensing resources and the starting time domain unit of each period of the second set of sensing resources can be indicated respectively, thereby reducing signaling overhead.

[0020] In one possible design, the frequency domain resources of the first sensing resource set are derived from frequency domain unit f. a Start; f a Satisfy: f a mod(D a )=H a , where H aThe value of the second parameter corresponding to the first set of sensing resources is D. The second parameter is used to indicate the starting frequency domain unit of the set of sensing resources. a This indicates the number of frequency domain units included in the first sensing resource set. The above allows for the configuration of H... a It can indicate the starting frequency domain unit of the first sensing resource set, reducing signaling overhead.

[0021] In one possible design, the first information configuration includes M sets of sensing resources, which include the first set of sensing resources, or the M sets of sensing resources include the first set of sensing resources and the second set of sensing resources, where the second set of sensing resources includes periodically repeating second sensing resources, and M is an integer greater than 1.

[0022] By using M sets of sensing resources, different devices can transmit sensing signals starting from the initial time domain unit of different sensing resource sets. If there is only one set of sensing resources, the device needs to wait for a time P1 before transmitting each time it triggers a sensing request. However, this application reduces the waiting time (e.g., to P1 / M) by using M sets of sensing resources. Furthermore, the sensing resources in different sets of sensing resources in this application are orthogonal in the frequency domain, thereby avoiding mutual interference in sensing performance between devices transmitting on different sets of sensing resources.

[0023] In one possible design, the starting time-domain units of the first and second sensing resource sets are different; and / or, the starting time-domain units of each cycle of the first and second sensing resource sets are different. With this design, different devices can transmit sensing signals starting from the starting time-domain units of different sensing resource sets. If there is only one set of sensing resources, the device needs to wait for a time P1 before transmitting each time it triggers a sensing request. This application, however, uses M sets of sensing resources, which reduces the waiting time (e.g., to P1 / M). Furthermore, the sensing resources within different sets of sensing resources are orthogonal in the frequency domain, thus preventing devices transmitting on different sets from interfering with each other's sensing performance.

[0024] In one possible design, the value of the first parameter G corresponding to the first set of sensory resources is... a The value of the first parameter G corresponding to the second set of sensory resources. bThe difference lies in that the first parameter is used to indicate the starting time-domain unit of the sensing resource set, or the first parameter is used to indicate the starting time-domain unit of each cycle of the sensing resource set. Through the above design, different devices can start sending sensing signals from the starting time-domain units of different sensing resource sets. If there is only one set of sensing resources, the device needs to wait for a time P1 before sending each time it triggers a sensing request. However, this application, by using M sets of sensing resources, can reduce the waiting time (e.g., to P1 / M). Furthermore, the sensing resources within different sets of sensing resources in this application are orthogonal in the frequency domain, thereby avoiding mutual interference in sensing performance between devices transmitting on different sets of sensing resources.

[0025] In one possible design, the first set of sensing resources is the set of sensing resources with the earliest starting time domain unit among the M sets of sensing resources; or, the first set of sensing resources is the set of sensing resources containing the sensing resource with the earliest starting time domain unit among the sensing resources included in the M sets of sensing resources. This design can reduce the waiting time for executing sensing services.

[0026] In one possible design, after the first sensing resource set becomes the third time domain unit, it is the sensing resource set with the earliest starting time domain unit among the M sets of sensing resource sets; or, after the first sensing resource set becomes the third time domain unit, it is the sensing resource set containing the sensing resource with the earliest starting time domain unit among the sensing resources included in the M sets of sensing resource sets; wherein, the third time domain unit is the time domain unit that triggers sensing, or, the third time domain unit is the time domain unit that triggers sensing and is separated by a third time domain offset after the time domain unit that triggers sensing; or, the third time domain unit is related to the time domain unit that triggers sensing, or, the third time domain unit is related to the time domain unit that triggers sensing and the third time domain offset; or, the third time domain unit is the time domain unit that receives the first information, or the third time domain unit is the time domain unit that receives the first information and is separated by a third time domain offset after the time domain unit that receives the first information; or, the third time domain unit is related to the time domain unit that receives the first information, or the third time domain unit is related to the time domain unit that receives the first information and the third time domain offset. This design can reduce the waiting time for executing sensing services.

[0027] In one possible design, the first information can also indicate a third time-domain offset.

[0028] In one possible design, the frequency domain units of the first sensing resource set and the second sensing resource set are different; and / or, the frequency domain units of the first sensing resource set and the second sensing resource set are different. This design avoids interference between sensing performance of devices transmitting on different sensing resource sets by ensuring the frequency domains of the sensing resources within different sets are orthogonal.

[0029] In one possible design, the value H of the second parameter corresponding to the first set of perceptual resources is...a The value H of the second parameter corresponding to the second set of sensory resources. b The difference lies in the fact that the second parameter indicates the starting frequency domain unit of the sensing resource set. This design reduces interference between sensing signals from different devices.

[0030] In one possible design, the intra-frame slot index of the first sensing resource is the same in at least two periods of the first sensing resource set; and / or, the symbol index of the first sensing resource is the same in the slot of the first sensing resource set in at least two periods of the first sensing resource set.

[0031] In one possible design, the RE index of the first sensing resource on the RB where the first sensing resource is located is the same for at least two periods of the first sensing resource set.

[0032] In one possible design, the first and second sensing resource sets share at least one of the following characteristics: the period of the sensing resource set, the number of sensing resources included in the sensing resource set, or the period of the sensing resources. This design can reduce signaling overhead.

[0033] In one possible design, the first and second sensing resource sets share at least one of the following characteristics: the number of frequency domain units included in the sensing resource set, the number of frequency domain units included in the sensing resource set, or the number of frequency domain units between two adjacent frequency domain units included in the sensing resource set. This design can reduce signaling overhead.

[0034] In one possible design, the first information indicates the period of the first sensing resource set in any of the following ways: the first information indicates the period of the first sensing resource set; or, the first information indicates the number of time-domain units included in the period of the first sensing resource set; or, the first information indicates the number of first sensing resources included in the first sensing resource set; or, the first information indicates both the period of the first sensing resources and the number of first sensing resources included in the first sensing resource set.

[0035] The above design can reduce signaling overhead.

[0036] In one possible design, the first information instructs the first set of sensory resources to repeat periodically in any of the following ways: the first information indicates the number of times the first set of sensory resources repeats periodically. That is, the periodic repetition information of the sensory resource set is the number of times the sensory resource set repeats periodically. Alternatively, the first information indicates at least one of the following: a start time-domain unit or an end time-domain unit of the first set of sensory resources, wherein the start time-domain unit is used to activate or enable the periodic repetition of the first set of sensory resources, and the end time-domain unit is used to deactivate or de-enable the periodic repetition of the first set of sensory resources. That is, the periodic repetition information of the sensory resource set is the start time-domain unit and / or the end time-domain unit of the sensory resource set.

[0037] The above design can reduce signaling overhead.

[0038] In one possible design, the first information further indicates a first time-domain offset and / or a second offset value; wherein the first time-domain offset is used to indicate that the starting time-domain unit of the first sensing resource set is the first time-domain unit; or, the first time-domain offset is used to indicate that the starting time-domain unit of the first sensing resource set is after the first time-domain unit; or, the first time-domain offset is used to indicate that the starting time-domain unit of the first sensing resource set is the starting time-domain unit of the first sensing resource set after the first time-domain unit; wherein, the first time-domain unit is a time-domain unit separated by the first time-domain offset after the time-domain unit where the first information is located; the second time-domain offset is used to indicate that the ending time-domain unit of the first sensing resource set is the second time-domain unit; or, the second time-domain offset is used to indicate that the ending time-domain unit of the first sensing resource set is after the second time-domain unit; or, the second time-domain offset is used to indicate that the ending time-domain unit of the first sensing resource set is the ending time-domain unit of the first sensing resource set after the second time-domain unit; wherein, the second time-domain unit is a time-domain unit separated by the second time-domain offset after the time-domain unit where the first information is located.

[0039] The above design allows for dynamic indication of the start time domain unit and / or end time domain unit of the first sensing resource set, reducing signaling overhead.

[0040] In one possible design, the first information indicates the frequency domain resources of the first sensing resource set in any of the following ways: the first information indicates at least two of the following: the starting frequency domain unit of the first sensing resource set, the ending frequency domain unit of the first sensing resource set, or the number of frequency domain units included in the first sensing resource set; or, the first information indicates the starting frequency domain unit of the first sensing resource set, the number of frequency domain units included in the first sensing resource set, or the number of frequency domain units between adjacent frequency domain units in the first sensing resource set; or, the first information indicates at least two of the following: the starting frequency domain unit of the first sensing resource set, the ending frequency domain unit of the first sensing resource set, or the frequency domain width of the first sensing resource set; or, the first information indicates the number of frequency domain units of the first sensing resource; or, the first information indicates the number of frequency domain units of the first sensing resource and the number of frequency domain units between adjacent frequency domain units in the first sensing resource.

[0042] In one possible design, the first information is used to configure a first set of sensing resources for at least one device, which includes a first device. The at least one device may be, for example, a first device and a second device, or, for example, a first device, a second device, and a fourth device. The movement speed of the at least one device is less than or equal to a threshold value.

[0043] The above design can indicate a common set of sensing resources for multiple devices, thereby supporting multiple devices to transmit sensing resources on the same set of sensing resources, reducing resource overhead and signaling overhead.

The periodic repetition information of the sensing resource sets refers to the start time-domain unit and / or the end time-domain unit of the sensing resource sets. The first information indicates the first field, or it can be described as the first information indicating the start time-domain unit information and / or the end time-domain unit information of the sensing resource sets.

[0045] Secondly, this application provides a sensing method, wherein the executing entity of the method is a third device, which can be a first device, or a chip or circuit on the third device side.

[0046] By providing a unified configuration method for the set of sensing resources, this application enables different sensing transmitters (e.g., the first device and the second device) to transmit sensing signals on the same sensing resources, thereby reducing the resource overhead of sensing at the system level.

[0047] Furthermore, since sensing can be continuous, the periodically recurring set of sensing resources in this application allows the sensing transmitter and receiver to accumulate sensing signals, thereby improving the accuracy of information for determining the sensing target.

[0050] By sending sensing signals to each sensing resource in the sensing resource set, it can be ensured that the only influencing factor on the changes in the sensing signals within the first time period Tw is the movement of the sensing target. This improves the accuracy of sensing and avoids interference between devices.

That is, the periodic repetition information of the sensory resource set is the number of times the sensory resource set repeats periodically. Alternatively, the first information indicates at least one of the following: a start time-domain unit or an end time-domain unit of the first set of sensory resources, wherein the start time-domain unit is used to activate or enable the periodic repetition of the first set of sensory resources, and the end time-domain unit is used to deactivate or de-enable the periodic repetition of the first set of sensory resources. That is, the periodic repetition information of the sensory resource set is the start time-domain unit and / or the end time-domain unit of the sensory resource set.

[0074] The above design can reduce signaling overhead.

[0075] In one possible design, the first information further indicates a first time-domain offset and / or a second offset value; wherein the first time-domain offset is used to indicate that the starting time-domain unit of the first sensing resource set is the first time-domain unit; or, the first time-domain offset is used to indicate that the starting time-domain unit of the first sensing resource set is after the first time-domain unit; or, the first time-domain offset is used to indicate that the starting time-domain unit of the first sensing resource set is the starting time-domain unit of the first sensing resource set after the first time-domain unit; wherein, the first time-domain unit is a time-domain unit separated by the first time-domain offset after the time-domain unit where the first information is located; the second time-domain offset is used to indicate that the ending time-domain unit of the first sensing resource set is the second time-domain unit; or, the second time-domain offset is used to indicate that the ending time-domain unit of the first sensing resource set is after the second time-domain unit; or, the second time-domain offset is used to indicate that the ending time-domain unit of the first sensing resource set is the ending time-domain unit of the first sensing resource set after the second time-domain unit; wherein, the second time-domain unit is a time-domain unit separated by the second time-domain offset after the time-domain unit where the first information is located.

[0076] The above design allows for dynamic indication of the start time domain unit and / or end time domain unit of the first sensing resource set, reducing signaling overhead.

[0077] In one possible design, the first information indicates the frequency domain resources of the first sensing resource set in any of the following ways: the first information indicates at least two of the following: the starting frequency domain unit of the first sensing resource set, the ending frequency domain unit of the first sensing resource set, or the number of frequency domain units included in the first sensing resource set; or, the first information indicates the starting frequency domain unit of the first sensing resource set, the number of frequency domain units included in the first sensing resource set, or the number of frequency domain units between adjacent frequency domain units in the first sensing resource set; or, the first information indicates at least two of the following: the starting frequency domain unit of the first sensing resource set, the ending frequency domain unit of the first sensing resource set, or the frequency domain width of the first sensing resource set; or, the first information indicates the number of frequency domain units of the first sensing resource; or, the first information indicates the number of frequency domain units of the first sensing resource and the number of frequency domain units between adjacent frequency domain units in the first sensing resource.

[0078] The above design allows for dynamic indication of the starting frequency domain unit and / or the ending frequency domain unit of the first sensing resource set, reducing signaling overhead.

[0079] In one possible design, the first information is used to configure a first set of sensing resources for at least one device, the at least one device including the first device. The speed of movement of the at least one device is less than or equal to a threshold value.

[0080] The above design can indicate a common set of sensing resources for multiple devices, thereby supporting multiple devices to transmit sensing resources on the same set of sensing resources, reducing resource overhead and signaling overhead.

[0081] Thirdly, this application provides a sensing method, wherein the executing entity of the method is a fourth device, which can be a first device, or a chip or circuit on the first device side. The first device can be a network device or a terminal device. The method includes: receiving first information, the first information being used to configure a first sensing resource set, the first sensing resource set including periodically repeating first sensing resources; and receiving a first sensing signal on the first sensing resource set, the first sensing signal being used to determine information about a sensing target.

[0082] By providing a unified configuration method for the set of sensing resources, this application enables different sensing transmitters (e.g., the first device and the second device) to transmit sensing signals on the same sensing resources, thereby reducing the resource overhead of sensing at the system level.

[0083] Furthermore, since sensing can be continuous, the periodically recurring set of sensing resources in this application allows the sensing transmitter and receiver to accumulate sensing signals, thereby improving the accuracy of information for determining the sensing target.

[0084] In one possible design, during the second time period, the transmission power of the sensing signal transmitted by each device on the first sensing resource set remains constant; or, during the second time period, the transmission power of the sensing signal transmitted by each device on the first sensing resource set changes in the same way.

[0085] By keeping the transmission power of the sensing signal constant or allowing it to change in the same way, the impact of power variations in the sensing signal can be avoided. This ensures that the only influencing factor on the sensing signal within the first time period Tw is the movement of the sensed target. This improves sensing accuracy and prevents interference between devices.

[0086] In one possible design, the method further includes receiving third information, which indicates a change in the transmission power of a sensing signal transmitted on the first sensing resource. This design allows the fourth device to determine the change in the transmission power of the sensing signal.

[0087] In one possible design, the second time period is the temporal resource of the first set of sensing resources. This design allows for controllable power of the transmitted sensing signals within the first set of sensing resources; consequently, the only influencing factor on changes in the received sensing signals is the motion of the sensing target.

[0088] In one possible design, each of the first sensing resources included in the first sensing resource set carries a sensing signal; and / or, each of the first sensing resources included in the first time period carries a sensing signal, the first time period being the accumulation duration of the first sensing signal; and / or, each of the first sensing resources included in at least one period of the periodically repeating first sensing resource set carries a sensing signal.

[0089] By sending sensing signals to each sensing resource in the sensing resource set, it can be ensured that the only influencing factor on the changes in the sensing signals within the first time period Tw is the movement of the sensing target. This improves the accuracy of sensing and avoids interference between devices.

[0090] In one possible design, the first set of sensing resources is periodically repeated. This design increases the accumulation time of the sensing signal, thereby improving the accuracy of the sensing.

[0091] In one possible design, the first information is used to configure a first set of sensing resources for the first and second devices. This allows multiple devices to transmit sensing signals on the same sensing resources, thereby increasing the dynamic components of the sensing signals and improving sensing accuracy.

[0092] In one possible design, the period of the first set of sensing resources is A1 times the first time period, or the first time period is B1 times the period of the first set of sensing resources, where the first time period is the accumulation duration of the first sensing signal, and A1 and B1 are both positive integers.

[0093] In one possible design, the period of the first set of sensing resources is C times the period of the first set of sensing resources. a times, of which C a It is a positive integer.

[0094] In one possible design, the first set of sensing resources includes D in the frequency domain. a Each frequency domain unit, the first sensing resource includes E in the frequency domain. a There are E frequency domain units, of which E frequency domain units are in D a Each frequency domain cell is evenly spaced, or, E a Each frequency domain unit is D a One frequency domain unit; D a E is an integer greater than 0. a It is greater than 0 and not greater than D. a Integers.

[0095] In one possible design, the temporal resources of the first set of sensory resources originate from temporal unit t. a Beginning; t a Satisfy: t a mod(P1 a ) = G a Among them, G a The value of the first parameter corresponding to the first set of sensing resources is P1. The first parameter indicates the starting time-domain unit of the sensing resource set, or, the first parameter indicates the starting time-domain unit of each period of the sensing resource set. a For the period of the first set of sensory resources, or, P1 a The number of temporal units included in the period of the first set of sensing resources. This allows for the configuration of a parameter G. a This allows for the indication of the starting time-domain unit for each cycle of the first sensing resource set, reducing signaling overhead. The first and second sensing resource sets correspond to different values ​​of the first parameter G. a and G b In other words, the first set of sensing resources and the second set of sensing resources for each period can be indicated in a unified way, that is, the starting time domain unit of each period of the first set of sensing resources and the starting time domain unit of each period of the second set of sensing resources can be indicated respectively, thereby reducing signaling overhead.

[0096] In one possible design, the frequency domain resources of the first sensing resource set are derived from frequency domain unit f. a Start; fa Satisfy: f a mod(D a )=H a , where H a The value of the second parameter corresponding to the first set of sensing resources is D. The second parameter is used to indicate the starting frequency domain unit of the set of sensing resources. a This indicates the number of frequency domain units included in the first sensing resource set. The above allows for the configuration of H... a It can indicate the starting frequency domain unit of the first sensing resource set, reducing signaling overhead.

[0097] In one possible design, the first information configuration includes M sets of sensing resources, which include the first set of sensing resources, or the M sets of sensing resources include the first set of sensing resources and the second set of sensing resources, where the second set of sensing resources includes periodically repeating second sensing resources, and M is an integer greater than 1.

[0098] By using M sets of sensing resources, different devices can transmit sensing signals starting from the initial time domain unit of different sensing resource sets. If there is only one set of sensing resources, the device needs to wait for a time P1 before transmitting each time it triggers a sensing request. However, this application reduces the waiting time (e.g., to P1 / M) by using M sets of sensing resources. Furthermore, the sensing resources in different sets of sensing resources in this application are orthogonal in the frequency domain, thereby avoiding mutual interference in sensing performance between devices transmitting on different sets of sensing resources.

[0099] In one possible design, the starting time-domain units of the first and second sensing resource sets are different; and / or, the starting time-domain units of each cycle of the first and second sensing resource sets are different. With this design, different devices can transmit sensing signals starting from the starting time-domain units of different sensing resource sets. If there is only one set of sensing resources, the device needs to wait for a time P1 before transmitting each time it triggers a sensing request. This application, however, uses M sets of sensing resources, which reduces the waiting time (e.g., to P1 / M). Furthermore, the sensing resources within different sets of sensing resources are orthogonal in the frequency domain, thus preventing devices transmitting on different sets from interfering with each other's sensing performance.

[0100] In one possible design, the value of the first parameter G corresponding to the first set of sensory resources is... a The value of the first parameter G corresponding to the second set of sensory resources. bThe difference lies in that the first parameter is used to indicate the starting time-domain unit of the sensing resource set, or the first parameter is used to indicate the starting time-domain unit of each cycle of the sensing resource set. Through the above design, different devices can start sending sensing signals from the starting time-domain units of different sensing resource sets. If there is only one set of sensing resources, the device needs to wait for a time P1 before sending each time it triggers a sensing request. However, this application, by using M sets of sensing resources, can reduce the waiting time (e.g., to P1 / M). Furthermore, the sensing resources within different sets of sensing resources in this application are orthogonal in the frequency domain, thereby avoiding mutual interference in sensing performance between devices transmitting on different sets of sensing resources.

[0101] In one possible design, the first set of sensing resources is the set of sensing resources with the earliest starting time domain unit among the M sets of sensing resources; or, the first set of sensing resources is the set of sensing resources containing the sensing resource with the earliest starting time domain unit among the sensing resources included in the M sets of sensing resources. This design can reduce the waiting time for executing sensing services.

[0102] In one possible design, after the first sensing resource set becomes the third time domain unit, it is the sensing resource set with the earliest starting time domain unit among the M sets of sensing resource sets; or, after the first sensing resource set becomes the third time domain unit, it is the sensing resource set containing the sensing resource with the earliest starting time domain unit among the sensing resources included in the M sets of sensing resource sets; wherein, the third time domain unit is the time domain unit that triggers sensing, or, the third time domain unit is the time domain unit that triggers sensing and is separated by a third time domain offset after the time domain unit that triggers sensing; or, the third time domain unit is related to the time domain unit that triggers sensing, or, the third time domain unit is related to the time domain unit that triggers sensing and the third time domain offset; or, the third time domain unit is the time domain unit that receives the first information, or the third time domain unit is the time domain unit that receives the first information and is separated by a third time domain offset after the time domain unit that receives the first information; or, the third time domain unit is related to the time domain unit that receives the first information, or the third time domain unit is related to the time domain unit that receives the first information and the third time domain offset. This design can reduce the waiting time for executing sensing services.

[0103] In one possible design, the first information can also indicate a third time-domain offset.

[0104] In one possible design, the frequency domain units of the first sensing resource set and the second sensing resource set are different; and / or, the frequency domain units of the first sensing resource set and the second sensing resource set are different. This design avoids interference between sensing performance of devices transmitting on different sensing resource sets by ensuring the frequency domains of the sensing resources within different sets are orthogonal.

[0105] In one possible design, the value H of the second parameter corresponding to the first set of perceptual resources is...a The value H of the second parameter corresponding to the second set of sensory resources. b The difference lies in the fact that the second parameter indicates the starting frequency domain unit of the sensing resource set. This design reduces interference between sensing signals from different devices.

[0106] In one possible design, the intra-frame slot index of the first sensing resource is the same in at least two periods of the first sensing resource set; and / or, the symbol index of the first sensing resource is the same in the slot of the first sensing resource set in at least two periods of the first sensing resource set.

This information includes, but is not limited to, shape, size, orientation, speed, position, distance between objects, or relative motion. The working principle of perception is as follows: the transmitting end sends a perception signal, and the receiving end receives the perception signal reflected and / or scattered by the perceived target (also known as the echo signal). Based on the received perception signal, the perception result is obtained, such as speed, distance, shape, and size. The perceived target can also be called a target, the object being detected, the object being sensed, or the object being sensed, etc., without limitation. The perceived target can be any tangible object in the environment capable of reflecting electromagnetic waves. For example, the perceived target can be a stationary object such as a building. Alternatively, the perceived target can also be a mobile object such as a vehicle, drone, or terminal device.

[0155] Sensing target: also known as the perceived target, target, etc. The characteristics of the target are derived based on the sensed signals.

[0156] (2) Sensing signals

[0157] A sensing signal can also be called a signal acting on sensing, a sensing reference signal, or a reference signal used for sensing. A sensing signal can be transmitted alone, or it can be transmitted together with a communication signal, or it can be a communication signal used for sensing services.

[0158] For example, the sensing signal in this embodiment can be any one of the following: channel state information-reference signal (CSI-RS), synchronization signal block (SSB), positioning reference signal (PRS), and sounding reference signal (SRS). The SRS can be a multi-input multi-output (MIMO) SRS or a positioning SRS, etc.

[0159] The sensed signal can propagate via the path of "sensing transmitter - sensing target - sensing receiver", or via the path of "sensing transmitter - sensing receiver", or via the path of "sensing transmitter - interference / environment - sensing receiver". In other words, the sensed signal can be a single path or a combination of the above paths, and the sensing receiver receives the sum of the signals from the above paths.

[0160] Therefore, in this embodiment, the transmitted sensing signal can be called sensing signal A, and the received sensing signal can be called sensing signal B. In fact, sensing signal A and sensing signal B are the same signal (e.g., both are referred to as sensing signals). During sensing, changes in sensing signal B compared to sensing signal A include changes caused by reflection or scattering from the sensing target, such as changes in the time and / or frequency domains of the sensing signal, and changes in the amplitude and / or phase of the sensing signal. These changes reflect, to some extent, the information of the sensing target.

[0161] (3) Resource Unit

[0162] Resources comprise two dimensions: time domain and / or frequency domain. The unit of time-domain resources is the time-domain unit, and the unit of frequency-domain resources is the frequency-domain unit.

[0163] Temporal units can be symbols, slots, mini-slots, sub-frames, frames, etc.

[0164] Frequency domain units can be resource elements (REs), resource blocks (RBs), channels, subchannels, control channel elements (CCEs), resource pools, bandwidth parts (BWPs), carriers, bands, etc.

[0165] The time-domain and frequency-domain units mentioned above can be combined arbitrarily. For example, a resource unit can be a time-frequency resource unit where the time-domain unit is a symbol and the frequency-domain unit is a resource particle. As another example, a resource unit can be a time-frequency resource unit where the time-domain unit is a symbol and the frequency-domain unit is a resource block.

[0166] In the embodiments of this application, the time-domain unit for transmitting the sensing signal can also be called the transmission occasion of the sensing signal, and the two can be used interchangeably.

[0167] (4) Accumulation of sensing signals

[0168] Because it's necessary to sense changes in the target over time, sensing signals need to be transmitted periodically. For example, the sensing transmitter periodically sends X sensing signals over a time interval. By comparing the changes in the sensing signals (e.g., the frequency of amplitude changes and / or the frequency of phase changes) during that time interval, it's determined whether the target is moving, or, more specifically, the speed of the moving target. The longer the sensing signals accumulate, the better the speed resolution.

[0169] In other words, it is necessary to determine the information of the perceived target based on at least one (e.g., X) sensing signals accumulated over a period of time. For ease of description, the following example uses the first sensing signal to determine the information of the perceived target, and the time period during which the first sensing signal is accumulated is referred to as the first time period Tw.

[0170] (5) Network device refers to a (radio)access network ((R)AN) device / RAN node. In the embodiments of this application, (R)AN and RAN are interchangeable. Network device may also be referred to as access network device, access network device apparatus, network apparatus, or wireless network device.

[0171] RAN can refer to cellular systems related to the 3rd Generation Partnership Project (3GPP), such as 5G / New Radio (NR) mobile communication systems, or future-oriented evolution systems / networks. RAN can also be an open RAN (O-RAN or ORAN), a cloud radio access network (CRAN), a virtualized RAN (vRAN), a non-terrestrial network (NTN), a satellite communication network, a high altitude platform station (HAPS) communication network, an integrated access and backhaul (IAB) communication network, or a reconfigurable intelligent surface (RIS) communication network. RAN can also be a communication system that integrates two or more of the above systems. RAN equipment can also be called RAN nodes, RAN entities, or access nodes. In future scenarios, network equipment may also evolve into other forms, for example, it may not be distinguished from core network equipment and may be collectively referred to as network equipment.

[0172] In one possible scenario, a RAN node can be a base station, an evolved NodeB (eNodeB), a next-generation NodeB (gNB), a base station in a future communication network, an access point (AP), a transmission reception point (TRP), a satellite, a transmitting point (TP), an access point (AP) in a satellite, an integrated access and backhaul (IAB) node, or access network equipment in a mobile switching center non-terrestrial network (NTN) communication system. This means it can be deployed on high-altitude platforms or satellites. RAN nodes can also be macro base stations, micro base stations, indoor stations, relay nodes, donor / host nodes, or radio controllers in CRAN scenarios. RAN nodes can also be servers, wearable devices, vehicles, or in-vehicle equipment. For example, in vehicle-to-everything (V2X) technology, the RAN node can be a roadside unit (RSU).

[0173] In another possible scenario, a RAN node can be a module or unit that performs some of the functions of a base station; or multiple RAN nodes can collaborate to assist terminal devices in achieving wireless access, with different RAN nodes performing some of the functions of the base station. For example, a RAN node can be a centralized unit (CU), a distributed unit (DU), or a radio unit (RU). The functions of a CU can be implemented by a single entity or by different entities. For example, the functions of a CU can be further divided, separating the control plane and the user plane and implementing them through different entities, namely the control plane CU entity (i.e., CU-control plane (CP) entity) and the user plane CU entity (i.e., CU-user plane (UP) entity). This CU-CP entity and CU-UP entity can be coupled with a DU to jointly complete the functions of the RAN node. CU and DU can be set up separately or included in the same network element, such as in a baseband unit (BBU). The RU can be included in radio frequency equipment or radio frequency units, such as remote radio units (RRUs), active antenna units (AAUs), or remote radio heads (RRHs). It is understood that a RAN node can be a CU node, a DU node, or a device including both CU and DU nodes. Furthermore, a CU can be classified as a RAN node within the RAN, or as a core network device within the core network; no limitation is made herein. Any of the CU (or CU-CP, CU-UP), DU, and RU units in this application can be implemented through software modules, hardware modules, or a combination of software and hardware modules.

[0174] The CU and DU can be configured according to the protocol layer functions of the wireless network they implement: for example, the CU can be configured to implement the functions of the Packet Data Convergence Protocol (PDCP) layer and above (such as the Radio Resource Control (RRC) layer and / or the Service Data Adaptation Protocol (SDAP) layer); the DU can be configured to implement the functions of protocol layers below the PDCP layer (such as the Radio Link Control (RLC) layer, the MAC layer, and / or the Physical (PHY) layer). For specific descriptions of the above protocol layers, please refer to the relevant 3GPP technical specifications or the technical specifications of other applicable communication protocols.

[0175] The above division of CU and DU processing functions according to protocol layers is merely an example; other division methods are also possible, and this application does not limit this. For example, in one design, CU or DU can be further divided into processing functions with protocol layers. In one design, some functions of the RLC layer and the functions of the protocol layers above the RLC layer are located in the CU, while the remaining functions of the RLC layer and the functions of the protocol layers below the RLC layer are located in the DU. In some examples, the CU may not have a PDCP layer, i.e., it may only include the RRC layer. CU-CP does not have PDCP-C. CU-UP may not have PDCP-U, or may not have CU-UP at all. In some examples, the DU may not have an RLC layer, only MAC and higher PHY layers. Furthermore, in some examples, there may be no CU, only the DU.

[0176] When the RAN is O-RAN, it can also have artificial intelligence (AI) capabilities. For example, O-RAN includes an intelligent controller. The intelligent controller can be a non-real-time RAN intelligent controller (RIC / non-RT RIC / NRTRIC) or a near-real-time RAN intelligent controller (RIC / nRT RIC / nRT RIC). A non-real-time RIC can be used to implement non-real-time intelligent management of RAN functions, enabling workflows including model training and updates, and guiding applications / functions in the nRT RIC based on policies. A near-real-time RIC can be used to implement near-real-time intelligent management of the RAN. Through data collection and related operations on the E2 interface, near-real-time control and optimization of O-RAN modules and resources are achieved.

[0177] In the embodiments of this application, the means for implementing the functions of the network device can be the network device itself, or it can be a means that supports the network device in implementing the functions, such as a chip system or a combination of devices or components that can implement the functions of the network device. This means can be installed in the network device. The embodiments of this application do not limit the specific technology or specific device form used in the network device.

[0178] (6) Terminal device. The terminal device involved in the embodiments of this application can be a wireless terminal device capable of receiving network device scheduling and instruction information. The terminal device can be called a terminal device, or it can also be called a user equipment (UE), terminal, mobile station (MS), mobile terminal (MT), etc. The terminal device can be a device that includes wireless communication functions (providing voice / data connectivity to the user). For example, a handheld device with wireless connection function, or an in-vehicle device, in-vehicle module, etc. Currently, examples of terminal devices include: mobile phones, tablets, laptops, PDAs, mobile internet devices (MIDs), wearable devices, virtual reality (VR) devices, augmented reality (AR) devices, wireless terminals in industrial control, wireless terminals in vehicle-to-everything (V2X) communication, wireless terminals in vehicle-to-everything (V2X) communication, intelligent vehicles, in-vehicle infotainment systems (or onboard transmitters) (T-boxes), and machine-to-machine / machine-type communication. Wireless terminals in communications (M2M / MTC) and Internet of Things (IoT) applications include communication devices and terminal devices. For example, terminal devices can be in-vehicle equipment, vehicle-mounted modules, vehicles, on-board units (OBUs), roadside units (RSUs), T-boxes, chips, or systems-on-chips (SoCs), which can be installed in vehicles, OBUs, RSUs, or T-boxes. Wireless terminals in industrial control can be cameras, robots, etc. Wireless terminals in smart homes can be televisions, air conditioners, robot vacuums, speakers, set-top boxes, etc.Terminal devices can also be V2X devices, such as smart cars, digital cars, unmanned cars, driverless cars, pilotless cars, autonomous cars, pure electric vehicles (EVs), hybrid electric vehicles (HEVs), range-extended electric vehicles (REEVs), plug-in hybrid electric vehicles (PHEVs), new energy vehicles, and roadside units (RSUs). Terminal devices can also be devices used in device-to-device (D2D) communication, such as electricity meters and water meters.

[0179] In the embodiments of this application, the device for implementing the functions of the terminal device can be the terminal device itself, or a device capable of supporting the terminal device in implementing the functions, such as a chip system or a combination of devices or components capable of implementing the functions of the terminal device. This device can be installed in the terminal device. The embodiments of this application do not limit the specific technology or specific device form used in the terminal device.

[0180] The preceding text introduced some terms and concepts involved in the embodiments of this application. The following text introduces the technical background involved in the embodiments of this application.

[0181] In the research of future communication systems, the integration of communication and sensing (also known as sensing) is an important technological direction. Communication systems possess sensing capabilities, enabling integrated design of communication and sensing. Similar to Long Term Evolution (LTE) / NR communication systems, sensing does not require a separate sensing network deployment or customized terminal equipment, resulting in low deployment, usage, and maintenance costs. Sensing functionality relies on network and terminal capabilities, continuously iterating and evolving.

[0182] The integration of communication and sensing takes many forms, such as using communication signals to perform sensing functions or using sensing results to assist communication. Sensing functions include target detection. Sensing targets (also called the sensed targets) include unmanned aerial vehicles (UAVs), human targets, automotive vehicles, automated guided vehicles, and objects creating hazards on roads / railways.

[0183] Currently, there is no relevant technology for sensing resource allocation. One possible solution is to allocate several symbols in a time slot for sensing in the time domain, and several REs in a frequency band (RB) for sensing in the frequency domain. However, this resource allocation method has the following three problems:

[0184] 1) Sensing Capacity Issue: The sensing transmitter sends a sensing signal, which is then scattered and reflected by the sensing target, and finally received by the sensing receiver. The changes in the received sensing signal relative to the transmitted signal reflect information about the sensing target, such as its speed and distance. Therefore, conventionally, different sensing devices (i.e., the sensing transmitter and / or the sensing receiver) need to perform sensing based on different sensing resources to avoid interference between sensing results. It's understandable that if the same sensing resources are used, it becomes impossible to distinguish which sensing target caused the change in the sensing signal.

[0185] There are many sensing devices. If the sensing resources of different devices are completely orthogonal (i.e., using different sensing resources), it will consume a large amount of total resources. The utilization efficiency of sensing resources will be low. Furthermore, since system resources are limited, allocating more resources to sensing services will correspondingly reduce the resources allocated to communication services, thus affecting the reliability of communication services. Therefore, with a limited total amount of sensing resources, the number of sensing devices that can be supported will be reduced.

[0186] 2) Perception Interference Problem: As described in the previous terminology introduction (4), it is necessary to determine the information of the sensing target (e.g., speed) based on the changes in the sensing signal within the first time period Tw. Assume that the first device senses the sensing target (assumed to be sensing target 1) on the first sensing resource, and the second device senses the sensing target (which could be sensing target 1 or another sensing target) on the first sensing resource. If the second device starts sending a sensing signal midway through the first time period Tw of the first device, such as... Figure 1 As shown, or, if the second device stops transmitting sensing signals midway through the first time period Tw of the first device, such as Figure 2As shown, this would cause a sudden change in the sensing signal on the first sensing resource. The sensing receiver cannot distinguish whether the change in the sensing signal is caused by the sensing target or by the mid-start / mid-stop of the second device, that is, it cannot determine the information of the sensing target based on the change in the sensing signal.

[0187] 3) Sensing signal energy issue: According to the terminology introduction (2) above, the sensing signal can propagate via the path of "sensing transmitter - sensing target - sensing receiver" or via the path of "sensing transmitter - (interference / environment -) sensing receiver". In this embodiment, the component propagating via the path of "sensing transmitter - sensing target - sensing receiver" can be called the dynamic component of the sensing signal; the component propagating via the path of "sensing transmitter - (interference / environment -) sensing receiver" can be called the static component of the sensing signal.

[0188] The movement of the sensed target causes changes in the dynamic components of the sensed signal, which in turn causes changes in the sensed signal received by the sensed receiver. Since the sensed signal received by the sensed receiver is a sum of dynamic and static components, changes in the received sensed signal represent information about the sensed target.

[0189] Due to the long propagation path and significant reflection / scattering losses, the dynamic component of the sensed signal has low energy reaching the sensing receiver. From a relative energy perspective, the dynamic component of the sensed signal has less energy than the sensed signal itself. If this ratio is less than a certain level, the sensing receiver cannot distinguish the changes caused by the dynamic component. From an absolute energy perspective, the sensed signal energy after reflection / scattering from the target is lower, resulting in a lower energy change in the received sensed signal. If this change is less than a certain level, the sensing receiver cannot distinguish it, and therefore cannot determine the information about the target.

[0190] For example, if the propagation distance of the path "sensing transmitter 1 - sensing target 1 - sensing receiver 1" is large, the signal energy of the dynamic component of the sensing signal reaching the sensing receiver is small, resulting in a smaller change energy in the received sensing signal.

[0191] Based on this, embodiments of this application provide a sensing method and apparatus for providing a configuration method for sensing resources. The method and apparatus are based on the same technical concept. Since the principles by which the method and apparatus solve problems are similar, the implementations of the apparatus and method can be mutually referred to, and repeated details will not be elaborated further.

[0192] The technical solutions provided in the embodiments of this application can be applied to integrated communication and sensing systems. An integrated communication and sensing system is a system that integrates communication and sensing systems. Sensing can also be understood as detection, such as detecting the position, distance, and angle of a target object. In an integrated communication and sensing system, one or more communication devices can be used as sensing (detection) nodes to form a sensing network. The working principle of sensing is to determine the attribute information (e.g., speed, distance, shape, size, etc.) of the sensed target by sending a signal and receiving the sensing signal (also called the echo signal) reflected by the sensed target. The sensed target can be a fixed object, such as mountains, forests, or buildings, or a movable object, such as a vehicle, drone, pedestrian, or terminal device. The communication device acting as a sensing node is also called a sensing device, sensing apparatus, or detector. Any device with sensing capabilities can be used as a sensing device; for example, a terminal device with sensing capabilities is a type of sensing device.

[0193] This application does not limit the type of communication system in the integrated communication and sensing system. For example, the communication system can be a communication system related to the 3rd Generation Partnership Project (3GPP). For example, the communication system can be LTE, the sixth generation (5G) mobile communication system (e.g., a new radio (NR) communication system), or it can be applied to other future mobile communication systems, or other similar communication systems. Other similar communication systems may include wireless fidelity (WIFI), vehicle-to-everything (V2X), Internet of Things (IoT) systems, narrowband Internet of Things (NB-IoT) systems, and so on.

[0194] Please see Figure 3 This is a schematic diagram illustrating various sensing modes provided in the embodiments of this application. Figure 3 The system uses the perceived target to indicate the vehicle and provides six perception modes. These six perception modes are: such as... Figure 3 The sensing mode of network device A shown in (1) is a self-transmitting and self-receiving mode, that is, network device A sends and receives sensing signals; such as Figure 3 The sensing mode of terminal device A shown in (2) is a self-transmitting and self-receiving mode, that is, terminal device A sends and receives sensing signals; such as Figure 3The sensing mode shown in (3) illustrates the transmission of sensing signals by network device A and the reception of sensing signals by network device B; as shown in (3). Figure 3 The sensing mode shown in (4) illustrates the sending of sensing signals by terminal device A and the receiving of sensing signals by terminal device B; for example... Figure 3 The sensing mode shown in (5) illustrates the transmission of sensing signals by network device A and the reception of sensing signals by terminal device A; such as Figure 3 The mode of terminal device A sending sensing signals and network device A receiving sensing signals is shown in (6) in the figure. Figure 3 The example is a smartphone.

[0195] The network architecture and business scenarios described in the embodiments of this application are for the purpose of more clearly illustrating the technical solutions of the embodiments of this application, and do not constitute a limitation on the technical solutions provided in the embodiments of this application. As those skilled in the art will know, with the evolution of network architecture and the emergence of new business scenarios, the technical solutions provided in the embodiments of this application are also applicable to similar technical problems.

[0196] In the embodiments of this application, "when," "if," and "if" all refer to the device taking corresponding actions under certain objective circumstances, and are not time-limited, nor do they require the device to perform a judgment action, nor do they imply any other limitations. Unless otherwise specified, "if" and "if" can be substituted, and "when" and "in the case of" can be substituted. "When" and "if" / "if" can be substituted.

[0197] In this application, the sensing service can also be replaced with sensing task / sensing session, etc.

[0198] It should be noted that the naming of each message / information in this application is only illustrative and limits the names of each message / information.

[0199] It is understood that this application does not specifically limit the structure of the execution entity of the method provided in the embodiments of this application. It can be applied to modules in terminal devices or network devices, as long as it can communicate according to the method provided in the embodiments of this application by running a program that records the code of the method provided in the embodiments of this application. The following description uses a first device and a second device for sending sensing signals, which can be understood as sensing transmitting ends. A fourth device for receiving sensing signals, which can be understood as a sensing receiving end. A third device for configuring sensing resources is also described as an example. The first device can be a terminal device or a network device, or a chip, chip system, module, etc., in the terminal device or network device. The second device can be a terminal device or a network device, or a chip, chip system, module, etc., in the terminal device or network device. The fourth device can be a terminal device or a network device, or a chip, chip system, module, etc., in the terminal device or network device. The third device can be a terminal device or a network device, or a chip, chip system, module, etc., in the terminal device or network device.

[0200] When the sensing transmitter that sends the sensing signal and the sensing receiver that receives the sensing signal are located in the same network device or terminal device, this sensing mode can be called mono-static sensing. For example, the first device and the fourth device can be the same network device, such as... Figure 3 The sensing mode shown in (1) is as follows. Alternatively, the first device and the fourth device can be the same terminal device, for example... Figure 3 The perception pattern shown in (2) is as follows.

[0201] When the sensing transmitter sending the sensing signal and the sensing receiver receiving the sensing signal are not in the same network device or terminal device, this sensing mode can be called bi-static sensing. For example, the first device and the fourth device can be different network devices, such as... Figure 3 The sensing mode shown in (3) is as follows. Alternatively, the first device and the fourth device can be different terminal devices, such as... Figure 3 The sensing mode shown in (4) is as follows. Alternatively, the first device is a network device and the fourth device is a terminal device, for example... Figure 3 The sensing mode shown in (5) is as follows. Alternatively, the first device is a terminal device and the fourth device is a network device, for example... Figure 3 The perception pattern shown in (6).

[0202] It is understood that sensing resources carry sensing signals, and sensing signals are transmitted on sensing resources. In this application, sensing resources can also be described as sensing signals. For example, a set of sensing resources including periodically repeating sensing resources can also be described as a set of sensing resources including periodically repeating sensing signals. Furthermore, a set of sensing resources can also be described as a set of sensing signals; the period of a sensing resource can also be described as the period of a sensing signal; the time-domain unit of a sensing resource can also be described as the time-domain unit of a sensing signal; the starting time-domain unit of a sensing resource can also be described as the starting time-domain unit of a sensing signal; the ending time-domain unit of a sensing resource can also be described as the ending time-domain unit of a sensing signal; the time-domain pattern of a sensing resource can also be described as the time-domain pattern of a sensing signal; the frequency-domain unit of a sensing resource can also be described as the frequency-domain unit of a sensing signal; the starting frequency-domain unit of a sensing resource can also be described as the starting frequency-domain unit of a sensing signal; the ending frequency-domain unit of a sensing resource can also be described as the ending frequency-domain unit of a sensing signal; the frequency-domain pattern of a sensing resource can also be described as the frequency-domain pattern of a sensing signal; the frequency-domain interval of a sensing resource can also be described as the frequency-domain interval of a sensing signal; the number of frequency-domain units of a sensing resource can also be described as the number of frequency-domain units of a sensing signal, and so on.

[0203] For ease of description, this application refers to the starting time-domain unit of a sensing resource in a set of sensing resources as the first starting time-domain unit. That is, within a period of a set of sensing resources, the starting time-domain unit of the sensing resource is referred to as the first starting time-domain unit. Similarly, the ending time-domain unit of a sensing resource in a set of sensing resources is referred to as the first ending time-domain unit. That is, within a period of a set of sensing resources, the ending time-domain unit of the sensing resource is referred to as the first ending time-domain unit.

[0204] The starting time domain unit of the sensing resource set is called the second starting time domain unit, and the ending time domain unit of the sensing resource set is called the second ending time domain unit.

[0205] The technical solutions in the embodiments of this application will now be described with reference to the accompanying drawings.

[0206] like Figure 4 The diagram shown is a flowchart illustrating a communication method provided in an embodiment of this application.

[0207] S401, the third device determines the first information.

[0208] The first information is used to configure the first set of sensing resources.

[0209] It should be noted that step S401 can be optional. For example, if the third device is a terminal device, step S401 can be omitted. Similarly, if the first and third devices are the same network device, step S401 can be omitted.

[0210] In one possible implementation, the first information is used to configure a first set of sensing resources for the first device and / or the second device. Therefore, the second device can also receive the first information, and both the first and second devices can transmit sensing signals on the first set of sensing resources. The first set of sensing resources includes first sensing resources. That is, both the first and second devices can transmit sensing signals on the first sensing resources included in the first set of sensing resources.

[0211] As one possible approach, the information used to configure the first set of sensing resources for the first device and the second device can be the same or different information.

[0212] For example, the first device and the second device receive the same first information, which indicates information about a first set of sensing resources.

[0213] For example, the first device and the second device receive different first information, which respectively indicate information of the first sensing resource set.

[0214] As one possible approach, the information configuring the first set of sensing resources for the first device and the fourth device in the first information can be the same.

[0215] For example, the first device and the fourth device receive the same first information, which indicates information about a first set of sensing resources. The first set of sensing resources includes first sensing resources. The first device transmits a first sensing signal on the first sensing resources, and the fourth device receives the first sensing signal on the first sensing resources.

[0216] For example, the second device and the fourth device receive the same first information, which indicates information about a first set of sensing resources. The first set of sensing resources includes first sensing resources. The second device transmits a second sensing signal on the first sensing resources, and the fourth device receives the second sensing signal on the first sensing resources.

[0217] The following sections introduce the sensory resource set from both the time and frequency domain perspectives. The sensory resource set referred to here can be the first sensory resource set, the second sensory resource set, or other sensory resource sets. For ease of explanation, the sensory resource set *m* is used to refer to a specific sensory resource set among multiple sensory sets. For example, when *m* = 1, the sensory resource set *m* is the first sensory resource set; when *m* = 2, the sensory resource set *m* is the second sensory resource set, and so on.

[0218] It should be noted that the following time-domain and frequency-domain features are optional. The time-domain and frequency-domain features can be implemented individually or in combination. For example, the set of sensing resources can refer to a set of time-domain resources whose features satisfy any one of the following time-domain features; or, the set of sensing resources can refer to a set of frequency-domain resources whose features satisfy any one of the following frequency-domain features; or, the set of sensing resources can refer to a set of time-frequency resources whose features satisfy any one of the following time-domain features, and whose features also satisfy any one of the following frequency-domain features.

[0219] 1. Time Domain

[0220] The set of perceived resources can be periodically repeated, such as... Figure 5 As shown. The period of the sensing resource set m can be P1. m P1 m The repetition period of a set of sensory resources, m, is represented by m = 1, 2, ..., M or m = 0, 1, ..., M-1, where M is the number of sets of sensory resources, or M is the number of sensory resource sets, and M is a positive integer. m is the index of a set of sensory resources, or an index of a set of sensory resource sets. In one exemplary description, a set of periodically repeating sensory resources can be referred to as a set of sensory resource sets. P1 m It is a positive integer. For example, P1 m It can be at least any one of {1,2,3,4,5,6,7,8,9,10,20,30,40,50,60,70,80,90,100}, in seconds or wireless frames. P1 m For example, it can be any one of the numbers from 1 to 100, or at least any one of the numbers {100, 200, 300, 400, 500, 600, 700, 800, 900, 1000, 2000, 3000, 4000, 5000, 6000, 7000, 8000, 9000, 10000}, with units of milliseconds, symbols, time slots, or radio frames. The period of the sensing resource set can also be understood as the duration corresponding to each sensing resource set period.

[0221] Taking the first set of sensory resources as an example, the period of the first set of sensory resources is P1. aUnderstandably, if the set of perceptual resources m is the first set of perceptual resources, then P1 m =P1 a Taking the second set of sensory resources as an example, the period of the second set of sensory resources is P1. b It is understandable that if the set of perceptual resources m is the second set of perceptual resources, then P1 m =P1 b Other sets of sensory resources are similar, and will not be described in detail here.

[0222] The temporal resources of a sensory resource set can be determined by at least two of the following parameters: the starting temporal unit of the sensory resource set, the ending temporal unit of the sensory resource set, and the period of the sensory resource set. For example, taking the first sensory resource set as an example, the temporal resources of the first sensory resource set can be determined by at least two of the following parameters: the starting temporal unit of the first sensory resource set, the ending temporal unit of the first sensory resource set, and the period of the first sensory resource set. Taking the second sensory resource set as an example, the temporal resources of the second sensory resource set can be determined by at least two of the following parameters: the starting temporal unit of the second sensory resource set, the ending temporal unit of the second sensory resource set, and the period of the second sensory resource set. Other sensory resource sets are similar and will not be described in detail here.

[0223] In one possible implementation, the period of the sensory resource set is an integer multiple of the first time period Tw. For example, taking the first sensory resource set as an example, the period of the first sensory resource set is A1 times the first time period, that is, the period P1 of the first sensory resource set. a The relationship between P1 and the first time period Tw satisfies: a =A1·Tw. Taking the second set of sensory resources as an example, the period of the second set of sensory resources is A2 times the period of the first time segment, that is, the period of the first set of sensory resources is P1. b The relationship between P1 and the first time period Tw satisfies: b =A2·Tw. Other sensory resource sets are similar, and will not be explained in detail here.

[0224] In another possible implementation, the first time period Tw is an integer multiple of the period of the sensory resource set. For example, taking the first sensory resource set as an example, the first time period is B1 times the period of the first sensory resource set, that is, the period P1 of the first sensory resource set. a The relationship between P1 and the first time period Tw satisfies: a =Tw / B1. Taking the second sensory resource set as an example, the first time period is B2 times the period of the second sensory resource set, that is, the period P1 of the second sensory resource set. b The relationship between P1 and the first time period Tw satisfies: b=Tw / B2. Other sensory resource sets are similar, and will not be described in detail here.

[0225] Where A1, A2, B1, and B2 are all positive integers. For example, A1 can be at least any one of {1,2,3,4,5,6,7,8,9,10}, and A2 can be at least any one of {1,2,3,4,5,6,7,8,9,10}. B1 can be at least any one of {1,2,3,4,5,6,7,8,9,10}, and B2 can be at least any one of {1,2,3,4,5,6,7,8,9,10}. An example is A1 = 1 or B1 = 1, which represents the period P1 of the first set of sensory resources. a This is equivalent to the first time period Tw, which can also be understood as the period P1 of the first set of sensory resources. a The default value is equal to the first time period Tw. Other sensory resource sets are similar, and will not be explained in detail here.

[0226] The first time interval Tw is inversely proportional to the velocity resolution value. The smaller the velocity resolution value required for the sensing service, the longer the first time interval Tw; similarly, the larger the velocity resolution value required for the sensing service, the shorter the first time interval Tw. Here, the velocity of the sensing target can be understood as the motion frequency of the sensing target; that is, the velocity resolution of the sensing target can be understood as the motion frequency resolution of the sensing target.

[0227] Alternatively, the first time interval Tw is inversely proportional to the speed accuracy value. The smaller the speed accuracy value required for the sensing service, the longer the first time interval Tw; similarly, the larger the speed accuracy value required for the sensing service, the shorter the first time interval Tw. Here, the speed accuracy of the sensed target can be understood as the accuracy of the sensed target's motion frequency.

[0228] For example, Figure 5 The diagram illustrates two cycles of the sensory resource set. In this diagram, the cycle P1 of the sensory resource set... m The first time interval is 10 seconds. The first time interval Tw is also 10 seconds, and their relationship satisfies P1. m =Tw.

[0229] There can be M sets of sensory resources. For different sets of sensory resources, the period can be the same or different. In one example, different sets of sensory resources may correspond to the same period, such as P1. For instance, the period of the first set of sensory resources is the same as the period of the second set. In another example, different sets of sensory resources may each correspond to their own period P1. m The periods of different sets of sensory resources can be the same or different. For example, the periods of the first set of sensory resources may be different from those of the second set of sensory resources.

[0230] The set of sensory resources can include periodically repeating sensory resources. For example, a first set of sensory resources can include periodically repeating first sensory resources, a second set of sensory resources can include periodically repeating second sensory resources, and so on. The period of the set of sensory resources can be an integer multiple of the period of the sensory resources, such as... Figure 5 As shown. The period of the sensing resources included in the sensing resource set m can be P2. m P2 m This represents the repetition period of the sensory resources in the sensory resource set m. The period P1 of the sensory resource set... m For the periodicity P2 of the perceived resources m C m The multiple, i.e., the period P1 of the perceived resource set. m and the cycle of perceived resources P2 m The relation satisfies: P1 m =C m P2 m C m This can represent the number of sensing resources within the time-domain sensing resource set m. Taking the first sensing resource set as an example, the period P1 of the first sensing resource set... a The period P2 of the first sensing resource a C a The multiple, i.e., the first perceptual resource set period P1 a and the cycle P2 of the first sensory resource a The relation satisfies: P1 a =C a ·P2 a Similarly, taking the second set of sensory resources as an example, the period P1 of the second set of sensory resources... b For the second sensory resource, period P2 b C b The second perceptual resource set period P1 is the multiple. b The period P2 of the second sensing resource b The relation satisfies: P1 b =C b P2 b .

[0231] Assume C m The period of the perception resource set is equal to 100, which means the period of the perception resource set is equal to 100 times the period of the perception resource. It can also be described as the default period of the perception resource set being equal to 100 times the period of the perception resource.

[0232] Among them, P2 m It is a positive integer. For example, P2 mIt is a positive integer, in milliseconds or time slots. For example, it can be any one of the numbers from 1 to 100, or at least one of the numbers {100, 200, 300, 400, 500, 600, 700, 800, 900, 1000, 2000, 3000, 4000, 5000, 6000, 7000, 8000, 9000, 10000}.

[0233] C m It is a positive integer. C m It can be any one of 1 to 100, or at least one of {100, 200, 300, 400, 500, 600, 700, 800, 900, 1000, 2000, 3000, 4000, 5000, 6000, 7000, 8000, 9000, 10000}.

[0234] For any two sets of sensory resources, the periods of the sensory resources included in the sets can be the same or different. In one example, different sets of sensory resources include sensory resources corresponding to the same period, for example, P2. In another example, different sets of sensory resources include sensory resources corresponding to their respective periods P2. m In this context, different sets of sensory resources may contain sensory resources with the same or different periods.

[0235] For different sets of sensory resources, the number of sensory resources included in each set can be the same or different. In one example, different sets of sensory resources may each contain the same number of sensory resources, for example, C. In another example, different sets of sensory resources may each contain their own number of sensory resources, C. m In this context, different sets of sensory resources may contain sensory resources with the same or different periods.

[0236] In summary, different sets of sensory resources (e.g., the first set of sensory resources and the second set of sensory resources) share at least one of the following characteristics: the period of the set of sensory resources, the number of sensory resources included in the set of sensory resources, or the period of the sensory resources.

[0237] The relationship between the period of the sensing resource set and the period of the sensing resources satisfies any one of the following:

[0238] 1) P1 = C·P2. This means that different sets of sensory resources can correspond to the same period. The sensory resources within different sets can correspond to the same period. The quantity of sensory resources within different sets can correspond to the same quantity.

[0239] 2)P1 m =C m• P2. It can be understood that different sets of sensory resources can correspond to their own periods, and the periods of different sets of sensory resources can be the same or different. Sensory resources within different sets of sensory resources can correspond to the same period. The number of sensory resources within different sets of sensory resources can correspond to their respective quantities, and the number of sensory resources included in different sets of sensory resources can be the same or different.

[0240] 3) P1 = C m P2 m It is understandable that different sets of sensory resources can correspond to the same period. The number of sensory resources included in different sets can correspond to their respective quantities; the number of sensory resources included in different sets can be the same or different. The sensory resources included in different sets can correspond to their respective periods; the periods of the sensory resources included in different sets can be the same or different.

[0241] 4)P1 m =C m P2 m It is understandable that different sets of sensory resources can correspond to their own periods, and the periods of different sets of sensory resources can be the same or different. The sensory resources included in different sets of sensory resources can correspond to the same period, and the periods of the sensory resources included in different sets of sensory resources can be the same or different. The number of sensory resources included in different sets of sensory resources can correspond to their respective quantities, and the number of sensory resources included in different sets of sensory resources can be the same or different.

[0242] Therefore, the period of the sensing resource set can be determined based on the relationship between the period of the sensing resource set and the period of the sensing signal.

[0243] The sensory resources included in a set of sensory resources (e.g., a first set of sensory resources, a second set of sensory resources, etc.) can be continuous or discrete in the time domain. For the case where the sensory resources included in the set of sensory resources are continuous in the time domain, this is equivalent to the period P2 of the sensory resources. m = 1 time-domain unit. For the case where the sensing resources included in the sensing resource set are discrete in the time domain, this is equivalent to the period P2 of the sensing resources. m )>1 time domain unit.

[0244] For example, Figure 5 Taking a set of sensory resources consisting of 100 periodically repeating sensory resources as an example, the periodicity value of the sensory resource set is P1. m The timeframe for resource perception is 10 seconds. (P2) m It is 200ms, and the relationship satisfies P1 = 100·P2 m .visible, Figure 5 The sensing resources included in the set of sensing resources are discrete in the time domain.

[0245] Within at least two periods of the set of sensed resources, the temporal pattern of the sensed resources within that set of sensed resources is the same.

[0246] A concrete example is that within each period of the sensing resource set, the temporal pattern of the sensing resources within that set is the same. Taking the first sensing resource set as an example, within each period of the first sensing resource set, the temporal pattern of the first sensing resources within that set is the same. Alternatively, it can be described as the first sensing signal being transmitted according to the same temporal pattern within each period of the first sensing resource set.

[0247] In one implementation, the temporal pattern of the sensing resources is the same in each period within the sensing resource set. This can be understood as the intra-frame slot index of the sensing resources being the same in each period of the sensing resource set. Alternatively, it can be described as the sensing signal being transmitted in at least one slot with the same index in each period of the sensing resource set, within the frame containing the sensing resource. The at least one slot included in the sensing resource can be a continuous set of at least one slot or a discrete set of at least one slot.

[0248] Taking the first set of sensing resources as an example, within each period of the first set of sensing resources, the intra-frame slot index of the first sensing resources in the frame where the first sensing resources are located is the same. Alternatively, it can be described as follows: in each period of the first set of sensing resources, in the frame where the first sensing resources are located, the first sensing signal is transmitted in at least one slot with the same index.

[0249] In another implementation, the temporal pattern of the sensing resources is the same in each period within the sensing resource set. This can be understood as follows: in each period of the sensing resource set, the symbol index within the time slot of the sensing resource is the same. Alternatively, it can be described as follows: in each period of the sensing resource set, within the frame containing the sensing resource, the sensing signal is transmitted in at least one time slot with the same index. The at least one time slot included in the sensing resource can be a continuous set of at least one time slot or a discrete set of at least one time slot.

[0250] Taking the first set of sensing resources as an example, within each period of the first set of sensing resources, the symbol index of the first sensing resource in the time slot where the first sensing resource is located is the same. Alternatively, it can be described that within each period of the first set of sensing resources, in the frame where the first sensing resource is located, the first sensing signal is transmitted in at least one time slot with the same index.

[0251] In another implementation, the temporal pattern of the sensing resources is the same in each period within the sensing resource set. This can be understood as follows: in each period of the sensing resource set, the intra-frame slot index of the sensing resources in the corresponding frame is the same, and in each period of the sensing resource set, the intra-slot symbol index of the sensing resources in the corresponding slot is the same. Specific examples are provided in the two implementation methods above and will not be repeated here.

[0252] Another concrete example is that, within at least two periods of the sensing resource set, the sensing signals are transmitted according to the same time-domain pattern. Taking the first sensing resource set as an example, within at least two periods of the first sensing resource set, the time-domain pattern of the first sensing resources is the same within the first sensing resource set. Alternatively, it can be described as that, within at least two periods of the first sensing resource set, the first sensing signal is transmitted according to the same time-domain pattern.

[0253] In one implementation, the temporal patterns of the sensing resources are identical across at least two periods within the sensing resource set. This can be understood as the intra-frame slot indices of the sensing resources being identical across at least two periods of the sensing resource set. Alternatively, it can be described as the sensing signals being transmitted on at least one slot with the same index within the frame containing the sensing resources across at least two periods of the sensing resource set. The at least one slot included in the sensing resources can be a continuous sequence of at least one slot or a discrete sequence of at least one slot.

[0254] In another implementation, the temporal patterns of the sensing resources are identical across at least two periods within the sensing resource set. This can be understood as the symbol indices within the time slots of the sensing resources being the same across at least two periods of the sensing resource set. Alternatively, it can be described as the sensing signals being transmitted in at least one time slot with the same index within the frame containing the sensing resources across at least two periods of the sensing resource set. The at least one time slot included in the sensing resources can be a continuous set of at least one time slot or a discrete set of at least one time slot.

[0255] Taking the first set of sensing resources as an example, within at least two periods of the first set of sensing resources, the symbol index of the first sensing resources in the time slot where the first sensing resources are located is the same. Alternatively, it can be described that within at least two periods of the first set of sensing resources, in the frame where the first sensing resources are located, the first sensing signal is transmitted in at least one time slot with the same index.

[0256] In another implementation, the temporal patterns of the sensing resources are the same across at least two periods within the sensing resource set. This can be understood as follows: the intra-frame slot indices of the sensing resources are the same across at least two periods within the sensing resource set, and the intra-slot symbol indices of the sensing resources are the same across at least two periods within the sensing resource set. Specific examples are provided in the two implementation methods above and will not be repeated here.

[0257] In the above method, the period of the sensing resource set can be an integer multiple of a frame, and / or the period of the sensing resource set can be an integer multiple of a time slot.

[0258] In another implementation, the temporal patterns of the sensing resources (e.g., the first set of sensing resources, the second set of sensing resources, etc.) are the same in at least two periods within the set of sensing resources. This can also be understood as: the following at least two parameters of the sensing resources included in at least two periods of the set of sensing resources are the same: the number of sensing resources, the starting temporal unit of the sensing resources, the ending temporal unit of the sensing resources, and the period of the sensing resources.

[0259] Taking a periodically repeating first set of sensory resources as an example, the fact that the temporal patterns of the sensory resources are the same in at least two periods within the set includes at least two of the following cases: the number of temporal units of the first sensory resources is the same in at least two periods of the first set of sensory resources; or, the starting temporal units of the first sensory resources are the same in at least two periods of the first set of sensory resources; or, the ending temporal units of the first sensory resources are the same in at least two periods of the first set of sensory resources; or, the sensory resource periods of the first sensory resources are the same in at least two periods of the first set of sensory resources.

[0260] In another implementation, the temporal patterns of the sensing resources (e.g., the first set of sensing resources, the second set of sensing resources, etc.) are the same in each period within the set of sensing resources. This can also be understood as: the following at least two parameters of the sensing resources included in each period of the set of sensing resources are the same: the number of sensing resources, the starting temporal unit of the sensing resources, the ending temporal unit of the sensing resources, and the period of the sensing resources.

[0261] Taking a periodically repeating first set of sensory resources as an example, the time-domain patterns of the sensory resources being the same in each cycle within the set of sensory resources include at least two of the following cases: the number of first sensory resources in each cycle of the first set of sensory resources is the same; or, the starting time-domain units of the first sensory resources in each cycle of the first set of sensory resources are the same; or, the ending time-domain units of the first sensory resources in each cycle of the first set of sensory resources are the same; or, the sensory resource cycles of the first sensory resources in each cycle of the first set of sensory resources are the same.

[0262] Optionally, the temporal patterns of the sensory resources included in different sensory resource sets can also be the same. For example, taking a first sensory resource set and a second sensory resource set as examples, the temporal pattern of the first sensory resource in the first sensory resource set and the temporal pattern of the second sensory resource in the second sensory resource set are the same.

[0263] Optionally, the first sensing resource in each period of the sensing resource set (e.g., the first sensing resource set, the second sensing resource set, etc.) is located on the first temporal unit of the sensing resource set; that is, the first temporal unit of the sensing resource set is aligned with the temporal unit of the first sensing resource within the sensing resource set. In other words, the starting temporal unit of the sensing resource within the sensing resource set is the starting temporal unit of the sensing resource set.

[0264] Optionally, the last sensing resource in each cycle of the sensing resource set (e.g., the first sensing resource set, the second sensing resource set, etc.) is located on the last temporal unit of the sensing resource set; that is, the last temporal unit of the sensing resource set is aligned with the temporal unit where the last sensing resource in the sensing resource set is located. In other words, the first start and end unit of the sensing resources in the sensing resource set is the end temporal unit of the sensing resource set.

[0265] For example, Figure 5 The temporal patterns of the sensory resources are identical in the first and second periods of the sensory resource set. In the temporal domain, each period of the sensory resource set includes 100 periods of repeated sensory resources.

[0266] 2. Frequency Domain

[0267] The set of sensory resources (e.g., the first set of sensory resources and / or the second set of sensory resources, etc.) includes D in the frequency domain. m For a frequency domain unit, D m This represents the number of frequency domain units included in the sensing resource set m. For example, taking the first sensing resource set as an example, the first sensing resource set includes D in the frequency domain. a Each frequency domain unit. It should be understood that if the set of sensing resources m is the first set of sensing resources, then D... m =D a .

[0268] Among them, D m It is a positive integer. D m For example, it can be at least any one of {1,2,3,4,5,6,7,8,9,10,20,30,40,50,60,70,80,90,100}.

[0269] For example, the frequency domain unit can be RE or RB.

[0270] As an alternative approach, the frequency domain resources of a set of sensing resources (e.g., a first set of sensing resources, a second set of sensing resources, etc.) can be determined by at least two of the following parameters: the second starting frequency domain unit of the sensing resource set, the second ending frequency domain unit of the sensing resource set, and the frequency domain width I of the sensing resource set. m The number of frequency domain units D included in the sensing resource set m The frequency domain spacing J between every two frequency domain units in the sensing resource set m .

[0271] Among them, I m I represents the frequency domain bandwidth of the sensing resource set m. m It is a positive integer, and the unit can be Hz, kHz, or MHz. m For example, it can be at least any one of {1,2,3,4,5,6,7,8,9,10,20,30,40,50,60,70,80,90,100}. Understandably, if the first set of perceptual resources is the set of perceptual resources m, then I... m =I a .

[0272] Among them, J m J represents the frequency domain spacing between every two frequency domain units in the sensing resource set m. m J is a positive integer. m The unit can be Hz, kHz, or MHz, or it can be RE or RB, J m For example, it can be at least any one of {1,2,3,4,5,6,7,8,9,10,20,30,40,50,60,70,80,90,100}. Understandably, if the first set of perceptual resources is the set of perceptual resources m, then J = J a .

[0273] For different sets of sensing resources, the frequency bandwidth of the sensing resource sets can be the same or different. In one example, different sets of sensing resources correspond to the same frequency bandwidth, for example, all being I. In another example, different sets of sensing resources correspond to their own frequency bandwidths I. m Wherein, for any two sets of sensing resources, the frequency domain width of the sensing resource sets can be the same or different.

[0274] For different sets of sensing resources, the frequency domain spacing between any two frequency domain units within a set can be the same or different. In one example, different sets of sensing resources can correspond to the same frequency domain spacing, for example, both being J. In another example, different sets of sensing resources correspond to their own respective frequency domain spacings J.m Wherein, for any two sets of sensing resources, the frequency domain spacing of the sensing resource sets can be the same or different.

[0275] The frequency domain resources or frequency domain units of a set of sensing resources (such as the first set of sensing resources, the second set of sensing resources, etc.) can be continuous or discrete.

[0276] In a scenario where the frequency domain resources or frequency domain units of a sensing resource set are continuous, the number of frequency domain units of a sensing resource set (e.g., a first sensing resource set, a second sensing resource set, etc.) can be equal to the frequency domain width of that sensing resource set.

[0277] In a context where the frequency domain resources or frequency domain units of a sensing resource set are discrete, the sensing resource set (e.g., a first sensing resource set, a second sensing resource set, etc.) can be comb-shaped. The frequency domain width of the sensing resource set can be determined by the number of frequency domain units in the sensing resource set and the frequency domain spacing between every two frequency domain units in the sensing resource set. For example, the relationship between the frequency domain width of the sensing resource set and the number of frequency domain units in the sensing resource set satisfies: I m =D m ·J m Or I m =(D m -1)·J m +1.

[0278] The set of sensing resources includes the E of the sensing resources in the frequency domain. m Each frequency domain unit. That is, in the time domain unit where the sensing resource resides, the set of sensing resources in the frequency domain includes the E of the sensing resources. m One frequency domain unit. Among them, E m This represents the number of frequency domain units of the sensing resources included in the sensing resource set m. It should be understood that if the sensing resource set m is the first sensing resource set, then E m =E a E m It is a positive integer. E m For example, it can be at least any one of {1,2,3,4,5,6,7,8,9,10,20,30,40,50,60,70,80,90,100}.

[0279] Optionally, within the time domain unit where the sensing resources reside, the sensing resources in the sensing resource set (e.g., the first sensing resource set, the second sensing resource set, etc.) are distributed with equal frequency domain spacing, and the frequency domain spacing between every two frequency domain units of the sensing resources is F. m .

[0280] For example, within the time domain unit where the first sensing resource resides, the first sensing resources within the first sensing resource set are distributed with equal frequency domain spacing. The frequency domain spacing between every two frequency domain units of the first sensing resource is F. m =F a .

[0281] For example, within the time domain unit where the second sensing resource resides, the second sensing resources within the second sensing resource set are distributed with equal frequency domain spacing. The frequency domain spacing between every two frequency domain units of the second sensing resource is F. m =F b .

[0282] Among them, F m This represents the frequency domain spacing between every two frequency domain units of the sensing resources included in the sensing resource set m. It should be understood that if the sensing resource set m is the first sensing resource set, then F... m =F a F m F is a positive integer. m The unit can be Hz, kHz, or MHz, or it can be RE or RB. Frequency domain spacing F m For example, it can be at least any one of {1,2,3,4,5,6,7,8,9,10,20,30,40,50,60,70,80,90,100}. This frequency domain interval F m This is the interval between every two frequency domain start positions of the sensing resource, or the interval between every two frequency domain end positions of the sensing resource. The interval between every two frequency domain end positions and the frequency domain start position of the sensing resource can be F′. m F′ m It can satisfy F′ m +1=F m The interval between each two frequency domain start positions and frequency domain end positions of the sensed resource can be F″. m Then F″ is satisfied m -1 = F m .

[0283] Optionally, within a set of sensing resources (e.g., a first set of sensing resources, a second set of sensing resources, etc.), the number of frequency domain units in the time domain where the sensing resources reside can be an integer multiple of the number of frequency domain units in the sensing resources. That is, within a set of sensing resources, the relationship between the number of frequency domain units in the set of sensing resources and the number of frequency domain units in the sensing resources satisfies: D m =F m ·E mFor example, taking the first set of sensing resources as an example, within the first set of sensing resources, the relationship between the number of frequency domain units of the first set of sensing resources and the number of frequency domain units of the first sensing resources in the time domain unit where the first sensing resources are located satisfies: D a =F a ·E a .

[0284] For example, Figure 5 In the process, the set of sensing resources includes 20 frequency domain units. In the time domain unit where the sensing resources are located, every 5 frequency domain units include 1 frequency domain unit of the sensing resources.

[0285] For example, a set of sensing resources comprises four frequency domain units. Within each set of sensing resources, the time domain unit containing the sensing resources includes the four frequency domain units of the sensing resources. Within the time domain unit containing the sensing resources, every five consecutive frequency domain units include one frequency domain unit of the sensing resource set.

[0286] The sensing resources within a set of sensing resources (e.g., the first set of sensing resources, the second set of sensing resources, etc.) can be continuous or discrete in the frequency domain.

[0287] When the sensing resources within a set of sensing resources are continuous in the frequency domain, the number of frequency domain units in the set of sensing resources (e.g., a first set of sensing resources, a second set of sensing resources, etc.) can be equal to the number of frequency domain units in the sensing resources themselves. For example, taking the first set of sensing resources as an example, the first set of sensing resources includes D in the frequency domain. a Each frequency domain unit, the first sensing resource includes E in the frequency domain. a Frequency domain units, where E a Each frequency domain unit is D a Each frequency domain unit. Optionally, in this approach, the set of sensing resources and the sensing resources can be configured via a single signaling signal.

[0288] When the perceptual resources within the perceptual resource set are discrete, the perceptual resources can be distributed in a comb-like pattern within the perceptual resource set. For example, the first perceptual resource can be distributed in a comb-like pattern within the first perceptual resource set.

[0289] In the case where the sensory resources within the aforementioned sensory resource set are discrete, if the frequency domain units of the sensory resource set are continuous, the number D of the frequency domain units of the sensory resource set... m The number of frequency domain units E of the sensing resources m The relationship satisfies: D m =F m ·E m For example, taking the first set of sensory resources as an example, the first set of sensory resources includes D in the frequency domain. aEach frequency domain unit, the first sensing resource includes E in the frequency domain. a Frequency domain units, where E m Each frequency domain unit in D m The frequency domain units are evenly spaced, for example, D m =F m ·E m Optionally, in this approach, the sensing resource set and sensing resources can be configured separately using two signaling methods.

[0290] In the case where the perceived resources within the aforementioned set of perceived resources are discrete, if the frequency domain units of the set of perceived resources are discrete, then the frequency domain units of the set of perceived resources are the same as the frequency domain units of the perceived resources, or vice versa. The number of frequency domain units in the set of perceived resources is equal to the number of frequency domain units of the perceived resources, or the default value for the number of frequency domain units in the set of perceived resources is equal to the number of frequency domain units of the perceived resources, i.e., D. m =E m The frequency domain spacing between any two frequency domain units in the sensing resource set is equal to the frequency domain spacing between any two frequency domain units of the sensing resource. Alternatively, the default value of the frequency domain spacing J between any two frequency domain units in the sensing resource set is equal to the frequency domain spacing between any two frequency domain units of the sensing resource, i.e., J... m =F m The frequency domain width of the sensing resource set is equal to the frequency domain width of the sensing resources, or, by default, the frequency domain width of the sensing resource set is equal to the frequency domain width of the sensing resources.

[0291] For example, taking the first set of sensory resources as an example, the first set of sensory resources includes D in the frequency domain. a Each frequency domain unit, the first sensing resource includes E in the frequency domain. a There are frequency domain units. The frequency domain units of the first sensing resource set are the same as the frequency domain units of the first sensing resource, or the frequency domain units of the first sensing resource are the same as the frequency domain units of the first sensing resource set. The number of frequency domain units in the first sensing resource set is equal to the number of frequency domain units in the first sensing resource, or the default value for the number of frequency domain units in the first sensing resource set is equal to the number of frequency domain units in the first sensing resource, i.e., D. a =E a The frequency domain spacing between any two frequency domain units in the first sensing resource set is equal to the frequency domain spacing between any two frequency domain units in the first sensing resource, or, the default value of the frequency domain spacing between any two frequency domain units in the first sensing resource set is equal to the frequency domain spacing between any two frequency domain units in the first sensing resource, i.e., J a =F aThe frequency domain width of the first set of sensing resources is equal to the frequency domain width of the first sensing resource, or, by default, the frequency domain width of the first set of sensing resources is equal to the frequency domain width of the first sensing resource. In the above cases, E a Each frequency domain unit is D a Each frequency domain unit.

[0292] In summary, different sets of sensing resources (e.g., the first set of sensing resources and the second set of sensing resources) share at least one of the following characteristics: the number of frequency domain units included in the set of sensing resources, the number of frequency domain units included in the sensing resources, or the number of frequency domain units between two adjacent frequency domain units included in the sensing resources. For example, the relationship between the number of frequency domain units in the set of sensing resources and the number of frequency domain units in the sensing resources within the set satisfies any one of the following:

[0293] 1) D = F·E. It can be understood that the number of frequency domain units in different sets of sensing resources can correspond to the same quantity. The number of frequency domain units in sensing resources within different sets of sensing resources can correspond to the same quantity. The frequency domain spacing between any two frequency domain units in sensing resources within different sets of sensing resources can correspond to the same frequency domain spacing.

[0294] 2)D m =F m •E. It can be understood that the number of frequency domain units in different sets of sensing resources can correspond to their respective quantities. The number of frequency domain units in sensing resources within different sets can correspond to the same quantity. The frequency domain spacing between any two frequency domain units in sensing resources within different sets can correspond to their respective frequency domain spacing.

[0295] 3) D = F m ·E m It can be understood that the number of frequency domain units in different sets of sensing resources can correspond to the same quantity. The number of frequency domain units in sensing resources within different sets can correspond to their respective quantities. The frequency domain spacing between any two frequency domain units in sensing resources within different sets can correspond to their respective frequency domain spacing.

[0296] 4)D m =F m ·E m It can be understood that the number of frequency domain units in different sets of sensing resources can correspond to their respective quantities. The number of frequency domain units in sensing resources within different sets can be the same. The frequency domain spacing between any two frequency domain units in sensing resources within different sets can correspond to their respective frequency domain spacing.

[0297] 5) D = E. It can be understood that the number of frequency domain units in different sets of sensing resources can correspond to the same quantity. The number of frequency domain units in sensing resources within different sets of sensing resources can correspond to the same quantity.

[0298] 6)D m =E m It can be understood that the number of frequency domain units in different sets of sensing resources can correspond to their respective quantities. The number of frequency domain units in sensing resources within different sets of sensing resources can correspond to their respective quantities.

[0299] Within at least two periods of the sensing resource set, the frequency domain patterns of the sensing resources are identical within that set.

[0300] A concrete example is that the frequency domain pattern of the sensing resources is the same in each period of the sensing resource set.

[0301] The above method can also be described as follows: within each period of the sensing resource set, the sensing signal is transmitted according to the same frequency domain pattern. Taking the first sensing resource set as an example, within each period of the first sensing resource set, the frequency domain pattern of the first sensing resource within the first sensing resource set is the same. Alternatively, it can also be described as follows: within each period of the first sensing resource set, the first sensing signal is transmitted according to the same frequency domain pattern.

[0302] In one implementation, the frequency domain pattern of the sensing resources is the same in each period within the sensing resource set. This can be understood as the RE index of the sensing resources on their respective RBs being the same in each period of the sensing resource set. Alternatively, it can be described as the sensing signal being transmitted on at least one RE with the same index in each period of the sensing resource set, within the frame containing the sensing resource. The at least one RE included in the sensing resources can be a continuous set of at least one RE or a discrete set of at least one RE.

[0303] Taking the first set of sensing resources as an example, within each period of the first set of sensing resources, the RE index of the first sensing resource on the RB where the first sensing resource is located is the same. Alternatively, it can be described as follows: within each period of the first set of sensing resources, on the frame where the first sensing resource is located, the first sensing signal is transmitted on at least one RE with the same index.

[0304] Another concrete example is that the frequency domain patterns of the sensing resources are the same within the sensing resource set for at least two periods.

[0305] The above method can also be described as follows: within at least two periods of the sensing resource set, the sensing signal is transmitted according to the same frequency domain pattern. Taking the first sensing resource set as an example, within at least two periods of the first sensing resource set, the frequency domain pattern of the first sensing resource is the same within the first sensing resource set. Alternatively, it can also be described as follows: within at least two periods of the first sensing resource set, the first sensing signal is transmitted according to the same frequency domain pattern.

[0306] In one implementation, the frequency domain patterns of the sensing resources are the same over at least two periods within the sensing resource set. This can be understood as the RE indices of the sensing resources on their respective RBs being the same over at least two periods of the sensing resource set. Alternatively, it can be described as the sensing signal being transmitted on at least one RE with the same index in the frame containing the sensing resource over at least two periods of the sensing resource set. The at least one RE included in the sensing resource can be a continuous set of at least one RE or a discrete set of at least one RE.

[0307] Taking the first set of sensing resources as an example, within at least two periods of the first set of sensing resources, the RE indices of the first sensing resources on the RB where the first sensing resources are located are the same. Alternatively, it can be described that within at least two periods of the first set of sensing resources, in the frame where the first sensing resources are located, the first sensing signal is transmitted on at least one RE with the same index.

[0308] In the above method, the frequency domain resources of the sensing resource set can be an integer multiple of RB.

[0309] In another implementation, the frequency domain patterns of the sensing resources are the same in at least two periods within the set of sensing resources. This can be understood as follows: in the time domain unit where the sensing resources are located, the sensing resources included in at least two periods of the set of sensing resources have the same at least two parameters: the number of frequency domain units of the sensing resources, the starting frequency domain unit of the sensing resources, the ending frequency domain unit of the sensing resources, the interval between every two frequency domain units of the sensing resources, and the frequency domain width of the sensing resources.

[0310] Taking a periodically repeating first set of sensing resources as an example, the fact that the frequency domain patterns of the sensing resources are the same in at least two periods within the set includes at least two of the following cases: the number of frequency domain units of the first sensing resources is the same in at least two periods of the first set of sensing resources; or, the first starting frequency domain units of the first sensing resources are the same in at least two periods of the first set of sensing resources; or, the first ending frequency domain units of the first sensing resources are the same in at least two periods of the first set of sensing resources; or, the interval between every two frequency domain units of the first sensing resources is the same in at least two periods of the first set of sensing resources; or, the frequency domain width of the first sensing resources is the same in at least two periods of the first set of sensing resources.

[0311] In another implementation, the frequency domain pattern of the sensing resources is the same in each period within the set of sensing resources. This can be understood as follows: in the time domain unit where the sensing resources are located, the sensing resources included in each period of the set of sensing resources have at least two of the following parameters that are the same: the number of frequency domain units of the sensing resources, the starting frequency domain unit of the sensing resources, the ending frequency domain unit of the sensing resources, the interval between every two frequency domain units of the sensing resources, and the frequency domain width of the sensing resources.

[0312] Taking a periodically repeating first set of sensing resources as an example, the frequency domain pattern of the sensing resources being the same in each cycle within the set includes at least two of the following cases: the number of frequency domain units of the first sensing resources in each cycle of the first set of sensing resources is the same; or, the first starting frequency domain unit of the first sensing resources in each cycle of the first set of sensing resources is the same; or, the first ending frequency domain unit of the first sensing resources in each cycle of the first set of sensing resources is the same; or, the interval between every two frequency domain units of the first sensing resources in each cycle of the first set of sensing resources is the same; or, the frequency domain width of the first sensing resources in each cycle of the first set of sensing resources is the same.

[0313] Optionally, the frequency domain patterns of the sensor resources included in different sets of sensor resources can also be the same. For example, taking a first set of sensor resources and a second set of sensor resources as examples, the frequency domain pattern of the first sensor resource in the first set of sensor resources and the frequency domain pattern of the second sensor resource in the second set of sensor resources are the same.

[0314] Optionally, within each period of the sensing resource set (e.g., the first sensing resource set and / or the second sensing resource set, etc.), in the time domain unit where the sensing resource is located, the lowest frequency domain unit of the sensing resource is located on the lowest frequency domain unit of the sensing resource set; that is, the lowest frequency domain unit of the sensing resource is aligned with the lowest frequency domain unit of the sensing resource set. In other words, the lowest frequency domain unit of the sensing resource within the sensing resource set is the lowest frequency domain unit of the sensing resource set.

[0315] Optionally, within each period of the sensing resource set (e.g., the first sensing resource set and / or the second sensing resource set, etc.), in the time domain unit where the sensing resource is located, the highest frequency domain unit of the sensing resource is located on the highest frequency domain unit of the sensing resource set; that is, the highest frequency domain unit of the sensing resource is aligned with the highest frequency domain unit of the sensing resource set. In other words, the highest frequency domain unit of the sensing resource within the sensing resource set is the highest frequency domain unit of the sensing resource set.

[0316] For example, Figure 5 The text indicates that the frequency domain patterns of the sensing resources are the same in the first and second periods of the sensing resource set. Within each period of the sensing resource set, the number of frequency domain units for the sensing resource in the time domain is 4, and the starting frequency domain unit of the sensing resource coincides with the starting frequency domain unit within the sensing resource set.

[0317] In the embodiments of this application, "on the time domain unit where the sensing resource is located" can be understood as: on the symbol where the sensing resource is located, on the time slot where the sensing resource is located, or on the symbol in the time slot where the sensing resource is located, etc.

[0318] The above introduces the set of sensing resources from the perspectives of the time domain and frequency domain.

[0319] Optionally, there can be one or more sets of sensory resources. Taking M sets of sensory resources as an example, the M sets of sensory resources include {sensory resource set 1, sensory resource set 2, ..., sensory resource set m, ..., sensory resource set M}.

[0320] In one possible implementation, the first information can configure M sets of sensing resources, where the first set of sensing resources can be one of the M sets. Optionally, the M sets of sensing resources may also include a second set of sensing resources.

[0321] The characteristics of the first and second sensory resource sets in the time and frequency domains can be found in the preceding descriptions. Optionally, the characteristics of the other sensory resource sets in the M groups of sensory resource sets in the time and frequency domains can also be found in the preceding descriptions.

[0322] The following sections describe how to determine the time and / or frequency domain of the M sets of sensing resources, or how to determine the time and / or frequency domain of any one of the M sets of sensing resources, from the perspectives of the time and frequency domains, respectively.

[0323] It should be noted that the time-domain and frequency-domain correspondences can be implemented separately or in combination. For example, the set of M sensing resources can refer to the set of M time-domain resources, whose characteristics satisfy any one of the following time-domain characteristics; or, the set of M sensing resources can refer to the set of M frequency-domain resources, whose characteristics satisfy any one of the following frequency-domain characteristics; or, the set of M sensing resources can refer to the set of M time-frequency resources, whose characteristics satisfy any one of the following time-domain characteristics, and whose characteristics also satisfy any one of the following frequency-domain characteristics.

[0324] 1. Time Domain

[0325] At least two sets of sensing resources in the M sets of sensing resources have different starting time-domain units. Alternatively, it can be described that at least two sets of sensing resources in the M sets of sensing resources have different starting time-domain units for each period. For example, the starting time-domain units of the first sensing resource set and the second sensing resource set are different. It can also be described that the starting time-domain units of each period of the first sensing resource set and the second sensing resource set are different. Figure 6 As shown.

[0326] In a specific example, the starting time-domain units of all M sets of sensing resources are different, or the starting time-domain units of each period of the M sets of sensing resources are different. Alternatively, it can be described that the starting time-domain units of each period of each set of sensing resources in the M sets of sensing resources are different. For example, the starting time-domain units of the first set of sensing resources and the second set of sensing resources are different. It can also be described that the starting time-domain units of each period of the first set of sensing resources and the second set of sensing resources are different.

[0327] For example, the M sets of sensing resources can satisfy at least one of the following:

[0328] The temporal units of the M sets of sensory resources are orthogonal, or the temporal units of the sensory resources included in the M sets of sensory resources are orthogonal.

[0329] The temporal units of the M sets of sensing resources are orthogonal. For example, the starting temporal unit of the first cycle of the first sensing resource set is time slot 1, and the ending temporal unit of the last cycle is time slot 6. The starting temporal unit of the first cycle of the second sensing resource set is time slot 7, and the ending temporal unit is time slot 12.

[0330] The M-group of sensory resources includes sensory resources whose temporal domain units are orthogonal, such as... Figure 7 As shown, for example, the time domain units where the sensing resources are located in the first set of sensing resources are time slots 1, 3, 5, and 7, and the time domain units where the sensing resources are located in the second set of sensing resources are time slots 2, 4, 6, and 8.

[0331] One way to determine the temporal resources of a set of sensory resources is as follows: the temporal resources of the set of sensory resources m are derived from the temporal unit t. m Beginning; t m Satisfy: t m mod(P1 m ) = G m Among them, G m The value of the first parameter corresponding to the sensing resource set m is given. The first parameter indicates the starting time-domain unit of the sensing resource set, or, the first parameter indicates the starting time-domain unit of each period of the sensing resource set, that is, G. m Used to indicate the starting time-domain unit of the sensing resource set m, or to indicate the starting time-domain unit of each period of the sensing resource set m. P1 m To perceive the periodicity of the resource set m, or, P1 m The number of time-domain units, such as time slots and frames, included in the period of the sensing resource set m.

[0332] Understandably, if the set of perceptual resources m is the first set of perceptual resources, then G m =G a , t m =t a P1 m =P1 a That is, the temporal resources of the first set of sensory resources originate from the temporal unit t. a Beginning; t a Satisfy: t a mod(P1 a ) = G a Among them, G a The value of the first parameter corresponding to the first set of sensing resources is used to indicate the starting time-domain unit of the sensing resource set, or, the first parameter is used to indicate the starting time-domain unit of each period of the sensing resource set, that is, G. a Used to indicate the starting time-domain unit of the first set of sensing resources, or, to indicate the starting time-domain unit of each period of the first set of sensing resources. P1 a For the period of the first set of sensory resources, or, P1 a The number of time-domain units included in the period of the first set of sensory resources.

[0333] If the set of perceptual resources m is the second set of perceptual resources, then G m =G b , t m =t b P1 m =P1 b That is, the temporal resources of the second set of sensory resources originate from the temporal unit t. b Beginning; t b Satisfy: t b mod(P1 b ) = G b Among them, G b The value of the first parameter corresponding to the second set of sensing resources is used to indicate the starting time-domain unit of the set of sensing resources, or, the first parameter is used to indicate the starting time-domain unit of each period of the set of sensing resources, that is, G. b Used to indicate the starting time-domain unit of the second sensing resource set, or, to indicate the starting time-domain unit of each period of the second sensing resource set. P1 b For the period of the second set of sensory resources, or, P1 b The number of time-domain units included in the period of the second set of sensory resources.

[0334] For example, if different sets of sensory resources have the same period (e.g., all are P1), then t m Satisfy: t m mod(P1) = G m Alternatively, if the number of time-domain units included in the periods of different sets of sensory resources is the same (e.g., all are P1), then t m Satisfy: t m mod(P1) = G m .

[0335] Optionally, at least two of the M sets of sensory resources have different initial temporal units. This can also be understood as at least two of the M sets of sensory resources corresponding to different G values. m Different. For example, G corresponds to the first set of sensory resources. a G corresponding to the second set of sensory resources b different.

[0336] For example, the starting temporal unit of each of the M sets of sensing resources is different. This can also be understood as the G corresponding to each of the M sets of sensing resources... m different.

[0337] Optionally, for a set of sensing resources m, the initial time-domain unit of the set of sensing resources is the initial time slot m of the set of sensing resources, i.e., the time-domain unit t. mThis indicates the slot number of the starting time slot. Alternatively, the starting time-domain unit of the sensing resource set is the starting frame m of the sensing resource set, i.e., time-domain unit t. m This indicates the starting frame number. The frame number can be, for example, a system frame number (SFN) or a direct frame number (DFN).

[0338] Taking a set of M sensing resources with a period of 100ms as an example, for the first set of sensing resources, G1 = G a If the value is 0, then the temporal resources of the first sensing resource set include the set of time slots corresponding to the first 100ms starting from time slot 0. The first sensing resource set also includes: the set of time slots corresponding to the first 100ms starting from time slot 100 (i.e., the second cycle), the set of time slots corresponding to the first 100ms starting from time slot 200 (i.e., the third cycle), the set of time slots corresponding to the first 100ms starting from time slot 300 (i.e., the fourth cycle), etc.

[0339] For the second set of sensory resources, G2 = G b If = 10, then the temporal resources of the second sensing resource set include the set of time slots corresponding to the first 100ms starting from time slot 10. The second sensing resource set also includes: the set of time slots corresponding to the first 100ms starting from time slot 110 (i.e., the second cycle), the set of time slots corresponding to the first 100ms starting from time slot 210 (i.e., the third cycle), the set of time slots corresponding to the first 100ms starting from time slot 310 (i.e., the fourth cycle), etc.

[0340] The determination of temporal resources for other sets of sensory resources is similar and will not be elaborated further.

[0341] If the period of each of the M sets of sensing resources is 100ms, then under a 15kHz SCS, taking the period of each of the M sets of sensing resources as including 100 time slots as an example, for the first set of sensing resources, G1 = 0, the time domain resources of the first set of sensing resources include the set of time slots corresponding to the 100 time slots starting from time slot 0. The first set of sensing resources in the period also includes: the set of time slots corresponding to the 100 time slots starting from time slot 100 (i.e., the second period), the set of time slots corresponding to the 100 time slots starting from time slot 200 (i.e., the third period), the set of time slots corresponding to the 100 time slots starting from time slot 300 (i.e., the fourth period), etc.

[0342] For the second sensing resource set, G2 = 10, the temporal resources of the second sensing resource set include the set of time slots corresponding to the 100 time slots starting from time slot 10. The periodic second sensing resource set also includes: the set of time slots corresponding to the 100 time slots starting from time slot 110 (i.e., the second period), the set of time slots corresponding to the 100 time slots starting from time slot 210 (i.e., the third period), the set of time slots corresponding to the 100 time slots starting from time slot 310 (i.e., the fourth period), and so on.

[0343] The determination of temporal resources for other sets of sensory resources is similar and will not be elaborated further.

[0344] Taking a period of 100ms for the first set of sensing resources and a period of 200ms for the second set of sensing resources as an example, for the first set of sensing resources, G1 = 0. Therefore, the temporal resources of the first set of sensing resources include the set of time slots corresponding to the first 100ms starting from time slot 0. The first set of sensing resources also includes: the set of time slots corresponding to the first 100ms starting from time slot 100 (i.e., the second period), the set of time slots corresponding to the first 100ms starting from time slot 200 (i.e., the third period), the set of time slots corresponding to the first 100ms starting from time slot 300 (i.e., the fourth period), and so on.

[0345] For the second sensing resource set, G2 = 10, the temporal resources of the second sensing resource set include the set of time slots corresponding to the 200ms starting from time slot 10. The second sensing resource set also includes: the set of time slots corresponding to the 200ms starting from time slot 210 (i.e., the second cycle), the set of time slots corresponding to the 200ms starting from time slot 410 (i.e., the third cycle), the set of time slots corresponding to the 200ms starting from time slot 610 (i.e., the fourth cycle), etc.

[0346] The determination of temporal resources for other sets of sensory resources is similar and will not be elaborated further.

[0347] If the period of the first sensing resource set is 100ms and the period of the second sensing resource set is 200ms, then under 15kHz SCS, the period of the first sensing resource set includes 100 time slots, and the period of the second sensing resource set includes 200 time slots. For the first sensing resource set, G1 = 0, then the time domain resources of the first sensing resource set include the set of time slots corresponding to the 100 time slots starting from time slot 0. The first sensing resource set of the period also includes: the set of time slots corresponding to the 100 time slots starting from time slot 100 (i.e., the second period), the set of time slots corresponding to the 100 time slots starting from time slot 200 (i.e., the third period), the set of time slots corresponding to the 100 time slots starting from time slot 300 (i.e., the fourth period), etc.

[0348] For the second sensing resource set, G2 = 10, the temporal resources of the second sensing resource set include the set of time slots corresponding to the 200 time slots starting from time slot 10. The periodic second sensing resource set also includes: the set of time slots corresponding to the 200 time slots starting from time slot 210 (i.e., the second period), the set of time slots corresponding to the 200 time slots starting from time slot 410 (i.e., the third period), the set of time slots corresponding to the 200 time slots starting from time slot 610 (i.e., the fourth period), and so on.

[0349] The determination of temporal resources for other sets of sensory resources is similar and will not be elaborated further.

[0350] 2. Frequency Domain

[0351] In the M sets of sensing resources, the frequency domain units of at least two sets of sensing resources are orthogonal, or, more specifically, the frequency domain units of the sensing resources included in at least two sets of sensing resources in the M sets are orthogonal. Here, "orthogonal" can also be described as "different".

[0352] For example, the frequency domain units of the first set of sensing resources and the frequency domain units of the second set of sensing resources are orthogonal, or it can be described that the frequency domain units of the first set of sensing resources and the frequency domain units of the second set of sensing resources are different.

[0353] In a specific example, the frequency domain units of the M sets of sensing resources are all different, or the frequency domain units of each period of the M sets of sensing resources are different. The frequency domain units of each set of sensing resources in the M sets of sensing resources are orthogonal, or it can also be described as the frequency domain units of the sensing resources included in each set of sensing resources in the M sets of sensing resources are orthogonal. Here, "orthogonal" can also be described as "different".

[0354] For example, the M sets of sensing resources can satisfy at least one of the following:

[0355] The frequency domain units of the M sets of sensing resources are orthogonal, or the frequency domain units of the sensing resources included in the M sets of sensing resources are orthogonal.

[0356] The frequency domain units of the M-group sensing resource set are orthogonal, such as Figure 6 As shown, for example, the starting frequency domain unit of the first sensing resource set is RE1 and the ending frequency domain unit is RE10, and the starting frequency domain unit of the second sensing resource set is RE11 and the ending frequency domain unit is RE20.

[0357] The frequency domain units of the sensing resources included in the M-group sensing resource set are orthogonal, such as... Figure 8As shown, for example, the frequency domain units where the sensing resources are located in the first set of sensing resources are RE1, RE3, RE5, and RE7, and the time domain units where the sensing resources are located in the second set of sensing resources are RE2, RE4, RE6, and RE8.

[0358] One way to determine the frequency domain resources of a set of sensing resources is as follows: the frequency domain resources of the set of sensing resources m are derived from frequency domain units f. m Start; f m Satisfy: f m mod(D m )=H m , where H m The value of the second parameter corresponding to the sensing resource set m is given. The second parameter indicates the starting frequency domain unit of the sensing resource set, that is, H. m D is used to indicate the starting frequency domain unit of the sensing resource set m. m Indicates the number of frequency domain units included in the first set of sensing resources.

[0359] Understandably, taking the first set of sensory resources as an example, then H m =H a f m =f a D m =D a That is, the frequency domain resources of the first set of sensing resources are from frequency domain unit f. a Start; f a Satisfy: f a mod(D a )=H a , where H a The value of the second parameter corresponding to the first set of sensing resources is given. The second parameter is used to indicate the starting frequency domain unit of the set of sensing resources, i.e., H. a Used to indicate the starting frequency domain unit of the first set of sensing resources. D a Indicates the number of frequency domain units included in the first set of sensing resources.

[0360] Taking the second set of sensory resources as an example, then H m =H b f m =f b D m =D b That is, the frequency domain resources of the second sensing resource set are derived from frequency domain unit f. b Start; f b Satisfy: f b mod(D a )=H b , where H bThe value of the second parameter corresponding to the second set of sensing resources is used to indicate the starting frequency domain unit of the set of sensing resources, i.e., H. b Used to indicate the starting frequency domain unit of the second set of sensing resources. D a Indicates the number of frequency domain units included in the first set of sensing resources.

[0361] For example, if different sets of sensing resources have the same number of frequency domain units (e.g., all D), then f m Satisfy: f m mod(D) = H m .

[0362] Optionally, the frequency domain units of at least two of the M sets of sensing resources are orthogonal. This can be understood as the H values ​​corresponding to at least two of the M sets of sensing resources being orthogonal. m They are different. For example, the value H of the second parameter corresponding to the first set of sensory resources is different. a The value H of the second parameter corresponding to the second set of sensory resources. b The difference lies in the fact that the second parameter is used to indicate the starting frequency domain unit of the sensing resource set.

[0363] For example, the frequency domain units of each of the M sets of sensing resources are orthogonal. This can be understood as the H corresponding to each of the M sets of sensing resources being orthogonal. m different.

[0364] Optionally, for a set of sensing resources m, the starting frequency domain unit of the set of sensing resources can be understood as the starting RB of the set of sensing resources with index m, i.e., the frequency domain unit f. m This represents the RB index of the starting RB. Alternatively, the starting frequency domain unit of the sensing resource set can be understood as the starting RE with index m in the sensing resource set, i.e., frequency domain unit f. m This indicates the RE index of the starting RE.

[0365] The above describes the M sets of sensing resources. The following describes how to configure the M sets of sensing resources.

[0366] In one possible approach, the first information can indicate the temporal resources of the sensing resource set. For example, the first information can indicate the period of the sensing resource set, etc.

[0367] In one implementation, the first information can indicate the period of the sensing resource set by direct indication. For example, taking the first sensing resource set as an example, the first information indicates the period of the first sensing resource set or the number of time-domain units included in the period of the first sensing resource set.

[0368] Understandably, if the M sets of sensing resources correspond to the same period, the first information can be a unified indication period for the M sets of sensing resources.

[0369] Similarly, if the number of time-domain units included in the period of the M sets of sensing resources is the same, the first information can be a unified indication of the number of time-domain units included in the period of the M sets of sensing resources.

[0370] If the M sets of sensing resources correspond to their respective periods, the third device can indicate the periods for the M sets of sensing resources respectively. Specifically, it can indicate the periods corresponding to the M sets of sensing resources respectively through one piece of information (e.g., the first piece of information), or it can indicate the periods corresponding to the M sets of sensing resources respectively through M pieces of information.

[0371] Similarly, if the number of time-domain units included in the period of the M sets of sensing resources corresponds to their respective quantities, the third device can indicate the number of time-domain units included in the period for each of the M sets of sensing resources. Specifically, it can indicate the number of time-domain units corresponding to each of the M sets of sensing resources through one piece of information (e.g., the first piece of information), or it can indicate the number of time-domain units corresponding to each of the M sets of sensing resources through M pieces of information.

[0372] In another implementation, the first information can also indirectly indicate the period of the sensing resource set by indicatively indicating the number of sensing resources included in the sensing resource set and / or the period of the sensing resources.

[0373] For example, taking a first set of sensing resources as an example, the first information can indicate the number of first sensing resources included in the first set of sensing resources. Optionally, the third device can also send second information, which can indicate the period of the first sensing resources.

[0374] For example, taking the first set of sensory resources as an example, the first information can indicate the period of the first sensory resources and the number of first sensory resources included in the first set of sensory resources.

[0375] For example, taking a first set of sensing resources as an example, the first information can indicate the period of the first sensing resources. Optionally, the third device can also send second information, which can indicate the number of first sensing resources included in the first set of sensing resources. Thus, the first device can determine the period of the first set of sensing resources based on the number of first sensing resources and the period of the first sensing resources.

[0376] Understandably, if the sensing resources in the M sets of sensing resources correspond to the same period, the first information can uniformly indicate the period of the sensing resources for the M sets of sensing resources. If the sensing resources in the M sets of sensing resources correspond to their own periods, the third device can indicate the period of the sensing resources for each of the M sets of sensing resources. Specifically, it can indicate the period of the sensing resources corresponding to each of the M sets of sensing resources with one piece of information, or it can indicate the period of the sensing resources corresponding to each of the M sets of sensing resources with M pieces of information.

[0377] If the M sets of sensing resources correspond to the same number of sensing resources, the first information can uniformly indicate the number of sensing resources for the M sets of sensing resources. If the M sets of sensing resources correspond to their respective numbers of sensing resources, the third device can indicate the number of sensing resources for each of the M sets of sensing resources. Specifically, it can indicate the number of sensing resources corresponding to each of the M sets of sensing resources with one piece of information, or it can indicate the number of sensing resources corresponding to each of the M sets of sensing resources with M pieces of information.

[0378] The first information can also indicate the starting temporal unit of the sensing resource set; for example, the first information can indicate the G of the sensing resource set m. m Taking the set of sensory resources m as the first set of sensory resources as an example, the first information can indicate the G of the first set of sensory resources. a .

[0379] Optionally, the sensing configuration end can indicate the number M of the sensing resource set through the first information.

[0380] In one implementation, the first information can directly indicate the number M of the sensing resource set.

[0381] For example, the first piece of information can directly indicate the number of sensory resource sets, M = 1. Therefore, the sensory resource set includes only one sensory resource set: the first sensory resource set.

[0382] For example, the first piece of information can directly indicate the number of sensory resource sets, M = 2. Therefore, the sensory resource sets include two sets: the first sensory resource set and the second sensory resource set.

[0383] In another implementation, the first information can indicate the value G or G' of the first parameter. m .

[0384] For example, the first information indicates the value G of the first parameter. That is, the first information indicates one first parameter, and the value of the first parameter is G. The set of perceptual resources indicated by the first information is the single set of perceptual resources, the first set of perceptual resources.

[0385] For example, the first information indicates the value G of the first parameter. The first parameter indicates the information of the starting time-domain unit of the first sensing resource set. The first sensing resource set includes information from time slot t. m The set of time slots corresponding to the initial time period P1, where time slot t m Satisfy t m mod(P1) = G1. Where P1 is the period of the first set of sensory resources.

[0386] For example, the first information indicates the value G of the first parameter and the number M of the sensory resource sets. That is, the first information indicates one first parameter, and the value of the first parameter is G. Among them, the first parameter of the M sensory resource sets has the same value, which is G. The sensory resource sets indicated by the first information include {sensory resource set 1, sensory resource set 2, ..., sensory resource set m, ..., sensory resource set M}.

[0387] For example, the first information indicates the value G of the first parameter. The first parameter uniformly indicates the information of the starting time-domain unit of the first sensing resource set and the information of the starting time-domain unit of the second sensing resource set. The first sensing resource set includes information from time slot t... m The set of time slots corresponding to the initial P11 time period, where time slot t m Satisfy t m mod(P11) = G. The second set of sensory resources includes data from time slot t. m The set of time slots corresponding to the initial P12 time period, where time slot t m Satisfy t m mod(P12) = G. Where P11 and P12 are the periods of the first and second sensory resource sets, respectively. P11 and P12 can be the same or different; this example does not impose any restrictions.

[0388] For example, the first information indicates the value G of M first parameters. m That is, the first information indicates M first parameters, and the values ​​of the M first parameters are G respectively. m (m = 1, 2, ..., M). This can be determined by the first parameter G. m The number of elements determines the number M of the sensory resource set. The sensory resource set indicated by the first information includes {sensory resource set 1, sensory resource set 2, ..., sensory resource set m, ..., sensory resource set M}.

[0389] For example, the first information indicates two first parameters, G1 and G2. m If the number of elements is 2 (i.e., G1 and G2), then the first information indicates M = 2 sets of sensing resources. G1 and G2 respectively indicate the information of the starting time-domain units of the first and second sensing resource sets. The first set of sensing resources includes information from time slot t.m The set of time slots corresponding to the initial P11 time period, where time slot t m Satisfy t m mod(P11) = G1. The second set of sensory resources includes those from time slot t. m The set of time slots corresponding to the initial P12 time period, where time slot t m Satisfy t m mod(P12) = G2. Where P11 and P12 are the periods of the first and second sensory resource sets, respectively. P11 and P12 can be the same or different; this example does not impose any restrictions.

[0390] In another implementation, the first information can indicate the period of the sensing resource set.

[0391] For example, the first information indicates a sensing resource set period P1. That is, the first information indicates one sensing resource set period, and the sensing resource set period is P1. The sensing resource set indicated by the first information is the first sensing resource set, which is a single sensing resource set.

[0392] For example, the first information indicates the period P1 of the sensing resource set. The period P1 of the sensing resource set indicates the repetition period of the first sensing resource set. The first sensing resource set may include data from time slot t. m The set of time slots corresponding to the initial time period P1, where time slot t m Satisfy t m mod(P1) = G1.

[0393] For example, the first information indicates the period P1 of the sensory resource set and the number M of the sensory resource sets. That is, the first information indicates one sensory resource set period, and the sensory resource set period is P1. Among them, the sensory resource set periods of the M sensory resource sets are the same, all being P1. The sensory resource sets indicated by the first information include {sensory resource set 1, sensory resource set 2, ..., sensory resource set m, ..., sensory resource set M}.

[0394] For example, the first information indicates the period P1 of the sensing resource set. The period P1 of the sensing resource set uniformly indicates the repetition period of the first sensing resource set and the repetition period of the second sensing resource set. The first sensing resource set may include information from time slot t. m The set of time slots corresponding to the initial time period P1, where time slot t m Satisfy t m mod(P11) = G1. The second set of sensory resources may include data from time slot t. m The set of time slots corresponding to the initial time period P1, where time slot t m Satisfy t mmod(P12) = G2. G1 and G2 can be the same or different; this example does not impose any restrictions.

[0395] For example, the first information indicates a periodic P1 of M sensory resource sets. m That is, the first information indicates M sets of sensing resources for a period of time, and the M sets of sensing resources for a period of time are P1 and P2 respectively. m (m = 1, 2, ..., M). This can be achieved by sensing the resource set period P1. m The number of elements determines the number M of the sensory resource set. The sensory resource set indicated by the first information includes {sensory resource set 1, sensory resource set 2, ..., sensory resource set m, ..., sensory resource set M}.

[0396] For example, the first information indicates two sets of sensory resources, periods P11 and P12. P1 m If the number of elements is 2 (i.e., P11 and P12), then the first information indicates M = 2 sets of sensing resources. P11 and P12 indicate the repetition period of the first set of sensing resources and the repetition period of the second set of sensing resources, respectively. The first set of sensing resources includes elements from time slot t. m The set of time slots corresponding to the initial P11 time period, where time slot t m Satisfy t m mod(P11) = G1. The second set of sensory resources includes those from time slot t. m The set of time slots corresponding to the initial P12 time period, where time slot t m Satisfy t m mod(P12) = G2. G1 and G2 can be the same or different; this example does not impose any restrictions.

[0397] In another implementation, the first information can indicate the period of the sensed resources. It can be understood that the first information indicates the period of the sensed resources within the set of sensed resources.

[0398] For example, the first information indicates a sensing resource period P2, that is, it indicates a sensing resource period P2 within the sensing resource set. In other words, the first information indicates one sensing resource period, and the sensing resource period is P2. The sensing resource set indicated by the first information is the first sensing resource set itself.

[0399] For example, the first information indicates the sensing resource cycle P2. The sensing resource cycle P2 indicates the repetition cycle of the sensing resources in the first set of sensing resources.

[0400] For example, the first information indicates the sensing resource period P2 and the number M of sensing resource sets, that is, it indicates the sensing resource period P2 and the number M of sensing resource sets within each sensing resource set. Specifically, the first information uniformly indicates one sensing resource period, which is P2. The sensing resource periods within the M sensing resource sets are the same, all being P2. The sensing resource sets indicated by the first information include {sensing resource set 1, sensing resource set 2, ..., sensing resource set m, ..., sensing resource set M}.

[0401] For example, the first information indicates the perception resource cycle P2. The perception resource cycle P2 uniformly indicates the repetition cycle of the perception resources in the first perception resource set and the repetition cycle of the perception resources in the second perception resource set.

[0402] For example, the first information indicates M sensing resource cycles P2 m That is, indicating the periodicity P2 of the sensing resources within the M sets of sensing resources. m That is, the first information indicates M sensing resource cycles, and the M sensing resource cycles are P2 and P3 respectively. m (m = 1, 2, ..., M). This can be achieved by sensing the resource cycle P2. m The number of elements determines the number M of the sensory resource set. The sensory resource set indicated by the first information includes {sensory resource set 1, sensory resource set 2, ..., sensory resource set m, ..., sensory resource set M}.

[0403] For example, the first information indicates two sensing resource cycles, P21 and P22. P2 m If the number of elements is 2 (i.e., P21 and P22), then the first information indicates M = 2 sets of sensory resources. P21 and P22 indicate the repetition period of the sensory resources in the first and second sets of sensory resources, respectively.

[0404] In another implementation, the first information can indicate the number of sensing resources. This can be understood as the first information indicating the number of sensing resources within the set of sensing resources.

[0405] For example, the first information indicates the number of sensing resources C, that is, the number of sensing resources C in the set of sensing resources. Specifically, the first information indicates one sensing resource cycle, with a number of sensing resources of C. The set of sensing resources indicated by the first information is the single set of sensing resources, the first set of sensing resources.

[0406] For example, the first piece of information indicates the number of sensing resources, C. The number of sensing resources, C, indicates the number of sensing resources in the first set of sensing resources.

[0407] For example, the first information indicates the number of sensing resources C and the number of sensing resource sets M, that is, it indicates the number of sensing resources C within a sensing resource set and the number of sensing resource sets M. The number of sensing resources in each of the M sensing resource sets is the same, which is C. That is, the first information indicates one sensing resource cycle, and the sensing resource cycle is P2. The sensing resource sets indicated by the first information include {sensing resource set 1, sensing resource set 2, ..., sensing resource set m, ..., sensing resource set M}.

[0408] For example, the first piece of information indicates the number of sensing resources C. The number of sensing resources C uniformly indicates the number of sensing resources in the first set of sensing resources and the number of sensing resources in the second set of sensing resources.

[0409] For example, the first information indicates the number C of M sensing resources. m That is, C indicates the number of sensing resources C within the M sets of sensing resources. m That is, the first information indicates M sensing resource cycles, and the M sensing resource cycles are P2 and P3 respectively. m (m = 1, 2, ..., M). The number of resources C can be sensed. m The number of elements determines the number M of the sensory resource set. The sensory resource set indicated by the first information includes {sensory resource set 1, sensory resource set 2, ..., sensory resource set m, ..., sensory resource set M}.

[0410] For example, the first piece of information indicates the number of two sensing resources, C1 and C2. m If the number of elements is 2 (i.e., C1 and C2), then the first information indicates M = 2 sets of sensory resources. C1 and C2 indicate the number of sensory resources in the first set of sensory resources and the second set of sensory resources, respectively.

[0411] The above implementation methods can be combined. For example, the first information can indicate the period of the sensing resource set and the first parameter. Alternatively, the first information can indicate the period of the sensing resources, the number of sensing signals within the sensing resource set, and the value of the first parameter. The first information can also indicate the period of the sensing resources, the number of sensing signals within the sensing resource set, and the value of the second parameter, and so on.

[0412] For example, the first piece of information could indicate P1, G1, and G2. m If the number of elements is 2 (i.e., G1 and G2), then the first information indicates M = 2 sets of sensing resources. Here, P1 represents the period of the first and second sets of sensing resources, and G1 and G2 respectively indicate the information of the starting time domain units of the first and second sets of sensing resources. The first set of sensing resources includes information from time slot t... m The set of time slots corresponding to the initial time period P1, where time slot t m Satisfy tm mod(P1) = G1. The second set of sensory resources includes those from time slot t. m The set of time slots corresponding to the initial time period P1, where time slot t m Satisfy t m mod(P1) = G2.

[0413] The first information can indicate P11, P12, G1, and G2. G m The number of P1 and P2 is 2 (i.e., G1 and G2). m If the number of elements is 2 (i.e., P11 and P12), then the first information indicates M = 2 sets of sensing resources. P1 and P2 represent the periods of the first and second sensing resource sets, respectively, and G1 and G2 indicate the information of the starting time domain units of the first and second sensing resource sets, respectively. The first sensing resource set includes elements from time slot t... m The set of time slots corresponding to the initial P11 time period, where time slot t m Satisfy t m mod(P11) = G1. The second set of sensory resources includes those from time slot t. m The set of time slots corresponding to the initial P12 time period, where time slot t m Satisfy t m mod(P12) = G2.

[0414] The first information can indicate P21, P22, C, G1, and G2. G m The number of P2 is 2 (i.e., G1 and G2). m If the number of elements is 2 (i.e., P21, P22), then the first information indicates M = 2 sets of sensing resources. Here, P21 and P22 represent the sensing resource periods of the first and second sets of sensing resources, respectively; G1 and G2 indicate the information of the starting time domain units of the first and second sets of sensing resources, respectively; and C indicates the number of sensing resources included in the first and second sets of sensing resources. Based on P21 and C, the period P11 of the first set of sensing resources can be determined. The first set of sensing resources includes elements from time slot t... m The set of time slots corresponding to the initial P11 time period, where time slot t m Satisfy t m mod(P11) = G1. Based on P22 and C, the period P12 of the second sensing resource set can be determined. The second sensing resource set includes data from time slot t. m The set of time slots corresponding to the initial P12 time period, where time slot t m Satisfy t m mod(P12) = G2.

[0415] The first information can indicate P21, P22, C1, C2, G1, and G2. G m The number of P2 is 2 (i.e., G1 and G2). m If the number of resources is 2 (i.e., P21, P22), then the first information indicates M = 2 sets of sensing resources. Here, P21 and P22 are the sensing resource periods of the first and second sensing resource sets, respectively; G1 and G2 indicate the information of the starting time domain units of the first and second sensing resource sets, respectively; and C1 and C2 indicate the number of sensing resources included in the first and second sensing resource sets, respectively. Based on P21 and C1, the period P11 of the first sensing resource set can be determined. The first sensing resource set includes resources from time slot t... m The set of time slots corresponding to the initial P11 time period, where time slot t m Satisfy t m mod(P11) = G1. Based on P22 and C2, the period P12 of the second sensing resource set can be determined. The second sensing resource set includes data from time slot t. m The set of time slots corresponding to the initial P12 time period, where time slot t m Satisfy t m mod(P12) = G2.

[0416] The first information can indicate P2, C1, C2, G1, and G2. G m The number of P2 is 2 (i.e., G1 and G2). m If the number of resources is 2 (i.e., P21, P22), then the first information indicates M = 2 sets of sensing resources. Here, P2 is the sensing resource period of the first and second sensing resource sets, G1 and G2 indicate the information of the starting time domain units of the first and second sensing resource sets, respectively, and C1 and C2 indicate the number of sensing resources included in the first and second sensing resource sets, respectively. Based on P2 and C1, the period P11 of the first sensing resource set can be determined. The first sensing resource set includes resources from time slot t... m The set of time slots corresponding to the initial P11 time period, where time slot t m Satisfy t m mod(P11) = G1. Based on P2 and C2, the period P12 of the second sensing resource set can be determined. The second sensing resource set includes data from time slot t. m The set of time slots corresponding to the initial P12 time period, where time slot t m Satisfy t m mod(P12) = G2.

[0417] The first information can indicate P2, C, G1, and G2. G m The number of P2 is 2 (i.e., G1 and G2).m If the number of elements is 2 (i.e., P21, P22), then the first information indicates M = 2 sets of sensing resources. Here, P2 is the sensing resource period of the first and second sensing resource sets, G1 and G2 respectively indicate the information of the starting time domain units of the first and second sensing resource sets, and C indicates the number of sensing resources included in the first and second sensing resource sets. Based on P2 and C, the period P1 of the first and second sensing resource sets can be determined. The first sensing resource set includes elements from time slot t... m The set of time slots corresponding to the initial time period P1, where time slot t m Satisfy t m mod(P1) = G1. The second set of sensory resources includes those from time slot t. m The set of time slots corresponding to the initial time period P1, where time slot t m Satisfy t m mod(P1) = G2.

[0418] The first information can also indicate the periodic repetition of the sensing resource set. For example, the sensing resource set repeats for Y periods, or the number of periods in the sensing resource set is Y. For instance, the first information can indicate the periodic repetition of the sensing resource set in one or more of the following two ways:

[0419] Method 1: Indicate the number of cycles Y of the sensing resource set, where Y is a positive integer. For example, taking the first sensing resource set as an example, the first information indicates the number of times the first sensing resource set cycle repeats, which is also the number of cycles of the first sensing resource set.

[0420] The periodic repetition of the sensing resource set can be semi-statically indicated, and the sensing resource set transmits for a total of Y cycles. The value of Y can be at least any one of {1,2,3,4,5,6,7,8,9,10,20,30,40,50,60,70,80,90,100}.

[0421] For example, if the first information indicates the number of cycles Y, then the sensing resource set is deenabled after transmitting Y cycles. The sensing transmitter, such as the first device, the second device, or other sensing transmitters, stops transmitting the sensing signal after transmitting Y sensing resource set cycles. Optionally, the fourth device may stop receiving the sensing signal after receiving Y sensing resource set cycles.

[0422] The first information can be configured with the number of periods Y for each set of sensing resources. For example, two different pieces of first information can indicate the number of periods Y1 for the first set of sensing resources and the number of periods Y2 for the second set of sensing resources, respectively.

[0423] Alternatively, the first information can be configured with the number of periods Y for the M sets of sensing resources. For example, in the same first information, it can indicate that the number of periods for both the first and second sets of sensing resources is Y. That is, the M sets of sensing resources correspond to the same number of periods Y.

[0424] Alternatively, the first information can also indicate the number of cycles Y corresponding to each of the M sets of sensing resources. m This refers to the number of cycles corresponding to each of the M sets of sensing resources. Here, m is an integer, taking values ​​of m = 1, 2, ..., M or m = 0, 1, ..., M-1. For example, in the same first information, indicators Y1 and Y2 indicate that the first set of sensing resources repeats Y1 cycles, and the second set of sensing resources repeats Y2 cycles.

[0425] Method 2: The first information may indicate the start time domain unit information and / or end time domain unit information of the sensing resource set. For example, taking the first sensing resource set as an example, the first information may indicate at least one of the following: the start time domain unit or the end time domain unit of the first sensing resource set, wherein the start time domain unit is used to activate or enable the periodic repetition of the first sensing resource set, and the end time domain unit is used to deactivate or de-enable the periodic repetition of the first sensing resource set.

[0426] In this embodiment of the application, in order to distinguish between the starting time-domain unit of the sensing resource set and the starting time-domain unit of the sensing resources, the starting time-domain unit of the sensing resources is referred to as the first starting time-domain unit, and the starting time-domain unit of the sensing resource set is referred to as the second starting time-domain unit. Similarly, the ending time-domain unit of the sensing resources is referred to as the first ending time-domain unit, and the ending time-domain unit of the sensing resource set is referred to as the second ending time-domain unit.

[0427] The periodic repetition of the perceived resource set can be dynamically activated and deactivated. The first information can indicate whether to dynamically activate or deactivate the periodic repetition of the perceived resource set via the first field. The value of the first field indicating whether to dynamically activate or deactivate the periodic repetition of the perceived resource set can be different.

[0428] For example, the first field is the first value, which indicates the information of the starting time domain unit of the sensing resource set, that is, the start (activation) of the periodic repetition of the sensing resource set. Here, the start (activation) of the periodic repetition of the sensing resource set can be understood as indicating the starting time domain unit of the sensing resource set.

[0429] For example, if the first field is the second value, it indicates the domain unit information at the end of the sensing resource set, that is, the end (deactivation) of the sensing resource set cycle repetition. Here, the end (deactivation) of the sensing resource set cycle repetition can be understood as indicating the domain unit at the end of the sensing resource set.

[0430] The first information can configure the starting time domain unit for each set of sensing resources. For example, two different first information can indicate the starting time domain unit K11 and the starting time domain unit K12, respectively, indicating that the periodic repetition of the first set of sensing resources starts (activates) at the starting time domain unit K11 and the periodic repetition of the second set of sensing resources starts (activates) at the starting time domain unit K12.

[0431] Alternatively, the first information can configure a unified starting time domain unit for the M sets of sensing resources. For example, in the same first information, it can uniformly indicate that the starting time domain unit of the first set of sensing resources and the starting time domain unit of the second set of sensing resources are both K1. That is, the M sets of sensing resources correspond to the same starting time domain unit, that is, they start (activate) the periodic repetition of the sensing resource sets at the same time unit (i.e., starting time domain unit K1).

[0432] Alternatively, the first information can also indicate that the M sets of sensing resources correspond to the starting time domain unit K1 respectively. m That is, the M sets of sensing resources correspond to their respective starting time domain units K1 m Where m is an integer, and can take the values ​​m = 1, 2, ..., M or m = 0, 1, ..., M-1. For example, in the same first information, the starting time domain unit K11 and the starting time domain unit K12 indicate the periodic repetition of the first sensory resource set starting (activating) at the starting time domain unit K11 and the periodic repetition of the second sensory resource set starting (activating) at the starting time domain unit K12, respectively.

[0433] The first information can be configured with an end domain unit for each set of sensing resources. For example, two different first information can indicate the end domain unit K21 and the end domain unit K22, respectively, indicating that the periodic repetition of the first set of sensing resources ends (deactivates) at the end domain unit K21 and the periodic repetition of the second set of sensing resources ends (deactivates) at the end domain unit K22.

[0434] Alternatively, the first information can configure a unified second end-start time domain unit for the M sets of sensing resources. For example, in the same first information, the end-start time domain unit of the first set of sensing resources and the end-start time domain unit of the second set of sensing resources are both K2. That is, the M sets of sensing resources correspond to the same end-start time domain unit, that is, they correspond to the same time unit (i.e., end-start time domain unit K2) to end (deactivate) the periodic repetition of the sensing resource sets.

[0435] Alternatively, the first information can also indicate that the M sets of sensing resources correspond to the domain unit K2 at the end of the process. m That is, the end domain unit K2 corresponding to each of the M sets of sensing resources. mWhere m is an integer, and can take the values ​​m = 1, 2, ..., M or m = 0, 1, ..., M-1. For example, in the same first information, the end domain unit K21 and the end domain unit K22 indicate that the periodic repetition of the first perceptual resource set ends (deactivates) at the end domain unit K21 and the periodic repetition of the second perceptual resource set ends (deactivates) at the end domain unit K22, respectively.

[0436] The first information can respectively indicate the value of the first field of the M sets of sensing resources. The first field of the first set of sensing resources is a first value, indicating the starting time domain unit of the first set of sensing resources, that is, the start (activation) of the periodic repetition of the set of sensing resources m; and / or, the first field of the second set of sensing resources is a second value, indicating the end time domain unit information of the second set of sensing resources, that is, the end (deactivation) of the periodic repetition of the second set of sensing resources.

[0437] The first piece of information can indicate the period of the M sets of sensing resources.

[0438] Example 1: The first information may include a sensing resource set period field, which takes the value P1, indicating that the period of the M sets of sensing resources is P1.

[0439] Example 2: The first information may include M periodic fields for the sensor resource set, where the values ​​of these M periodic fields are P11, P12, ..., P1 m ,…,P1 M , respectively indicating the period of the M groups of sensing resource sets.

[0440] Example 3: The first information may include N periodic fields for the sensing resource set, where the values ​​of these N periodic fields are P11, P12, ..., P1 m ,…,P1 N The M sensing resource set period fields indicate the sensing resource set periods P11, P12, ..., P1 of the M sets of sensing resource sets, respectively. m ,…,P1 M Where N is an integer greater than or equal to M. That is, the first M periodic fields of the N periodic fields of the sensory resource sets respectively indicate the period of the M sensory resource sets; or, the last M periodic fields of the N periodic fields of the sensory resource sets respectively indicate the period of the M sensory resource sets.

[0441] For example, the first information may include N periodic fields for the set of sensed resources, where the values ​​of these N periodic fields are P11, P12, ..., P1 m ,…,P1 NThe M sensing resource set period fields indicate the sensing resource set periods P11, P12, ..., P1 of the M sets of sensing resource sets, respectively. m ,…,P1 M The remaining NM sensing resource sets have a third value for the periodic field. This third value can be either all 0s or all 1s.

[0442] Another example is that the first information may include N periodic fields for the sensory resource set, where the values ​​of these N periodic fields are P11, P12, ..., P1 m ,…,P1 N The M sensing resource set period fields indicate the sensing resource set periods P11, P12, ..., P1 of the M sets of sensing resource sets, respectively. m ,…,P1 M The values ​​of the remaining NM sensing resource set periodic fields are the same as the value of the first sensing resource set periodic field, or the values ​​of the remaining NM sensing resource set periodic fields are the same as the value of the Mth sensing resource set periodic field.

[0443] Another example is that the first information may include N sensing resource set period fields, and the first information also indicates the number M of sensing resource sets. The first M sensing resource set period fields among the N sensing resource set period fields respectively indicate the sensing resource periods P1, P2, ..., P of the M groups of sensing resource sets. m ,…,P M Alternatively, the last M periodic fields of the N periodic fields of the sensory resource sets respectively indicate the sensory resource periods P1, P2, ..., P of the M groups of sensory resource sets. m ,…,P M

[0444] Optionally, the first information may also indicate a first time-domain offset L.

[0445] Wherein, the first time-domain offset L is used to indicate that the starting time-domain unit of the sensing resource set (e.g., the first sensing resource set, etc.) is the first time-domain unit, wherein the first time-domain unit is the time-domain unit after the time-domain unit where the first information is located, separated by the first time-domain offset; that is, the first time-domain offset L represents the first time-domain offset L after the starting time-domain unit of the sensing resource set is located in the time-domain unit where the first information is located.

[0446] Alternatively, the first time-domain offset is used to indicate that the starting time-domain unit of the sensing resource set, for example, the first sensing resource set, is after the first time-domain unit, where the first time-domain unit is the time-domain unit after the time-domain unit where the first information is located, separated by the first time-domain offset. That is, or, the first time-domain offset L indicates that the starting time-domain unit of the sensing resource set is after the first time-domain unit after the time-domain unit where the first information is located.

[0447] Alternatively, the first time-domain offset is used to indicate that the starting time-domain unit of the sensing resource set, such as the first sensing resource set, is the starting time-domain unit of the first sensing resource set after the first time-domain unit; wherein, the first time-domain unit is the time-domain unit after the time-domain unit where the first information is located, separated by the first time-domain offset. That is, the first time-domain offset L indicates that the starting time-domain unit of the sensing resource set is the starting time-domain unit of the first sensing resource set after the first time-domain offset L after the time-domain unit where the first information is located.

[0448] Optionally, the first time-domain offset may include the time for processing the first information, the time for generating the sensing signal, and / or the waiting time, etc.

[0449] Optionally, the first information may also indicate a second time-domain offset O.

[0450] The second time-domain offset is used to indicate that the end time-domain unit of the sensing resource set, such as the first sensing resource set, is the second time-domain unit. The second time-domain unit is the time-domain unit that follows the time-domain unit containing the first information by the second time-domain offset. In other words, the second time-domain offset 0 indicates that the end time-domain unit of the sensing resource set is the second time-domain offset 0 after the time-domain unit containing the first information.

[0451] Alternatively, the second time-domain offset is used to indicate that the end time-domain unit of the sensing resource set, such as the first sensing resource set, is after the second time-domain unit, where the second time-domain unit is the time-domain unit after the time-domain unit where the first information is located, separated by the second time-domain offset. That is, or, the second time-domain offset 0 indicates that the end time-domain unit of the sensing resource set is after the second time-domain offset 0 after the time-domain unit where the first information is located.

[0452] Alternatively, the second time-domain offset is used to indicate that the end-time domain unit of the sensing resource set, such as the first sensing resource set, is the end-time domain unit of the first sensing resource set after the second time-domain unit, wherein the second time-domain unit is the time-domain unit after the time-domain unit where the first information is located, separated by the second time-domain offset. That is, the second time-domain offset 0 indicates that the end-time domain unit of the sensing resource set is the end-time domain unit of the first sensing resource set after the second time-domain offset 0 after the time-domain unit where the first information is located.

[0453] Optionally, the second time-domain offset includes the time for processing the first information, the cancellation of sensing signal transmission, and / or the waiting time.

[0454] Optionally, the first information can individually indicate the first time-domain offset L of the set of sensing resources, or it can uniformly indicate the first time-domain offset L of the M sets of sensing resources.

[0455] In method A-1, the first information can indicate a first time-domain offset L for each set of sensing resources. For example, two different pieces of first information can indicate the first time-domain offset of the first set of sensing resources and the first time-domain offset of the second set of sensing resources, respectively.

[0456] In method A-2, the first information can uniformly indicate the first time-domain offset L of the M sets of sensing resources. For example, in the same first information, the first time-domain offset of the first set of sensing resources and the second set of sensing resources is indicated as L. That is, the M sets of sensing resources correspond to the same first time-domain offset L.

[0457] In method A-3, the first information can also indicate the first temporal offset L corresponding to each of the M sets of sensing resources. m That is, the first temporal offset L corresponding to each of the M sets of sensing resources. m Where m is an integer, and can take the values ​​m = 1, 2, ..., M or m = 0, 1, ..., M-1. For example, in the same first information, indicators L1 and L2 represent the first time-domain offset of the first sensing resource set and the first time-domain offset of the second sensing resource set, respectively.

[0458] If the first information uniformly indicates a first time-domain offset L (i.e., method A-2 above), this first time-domain offset L can represent the starting time-domain unit of the first of the M starting time-domain units of the M sensing resource sets after the first time-domain unit where the first information is located. Taking the first time-domain offset L indicating the first sensing resource set as an example, the sensing resource set corresponding to this first starting time-domain unit is the first sensing resource set.

[0459] Optionally, the first information can individually indicate the second time-domain offset O of the sensing resource set, or it can uniformly indicate the second time-domain offset O of the M sets of sensing resource sets.

[0460] In method B-1, the first information can indicate a second time-domain offset O for each set of sensing resources. For example, two different pieces of first information can indicate the second time-domain offset value of the first set of sensing resources and the second time-domain offset of the second set of sensing resources, respectively.

[0461] In method B-2, the first information can uniformly indicate the second time-domain offset O of the M sets of sensing resources. For example, the same first information indicates the second time-domain offset O of the first and second sets of sensing resources. That is, the value of the second time-domain offset of each set of sensing resources is 0, and the M sets of sensing resources correspond to the same second time-domain offset O.

[0462] In method B-3, the first information can also indicate the second time-domain offset O corresponding to each of the M sets of sensing resources. m That is, the second time-domain offset O corresponding to each of the M sets of sensing resources. m Where m is an integer, and can take the values ​​m = 1, 2, ..., M or m = 0, 1, ..., M-1. For example, in the same first information, indicators O1 and O2 represent the second time-domain offset of the first sensing resource set and the second time-domain offset of the second sensing resource set, respectively.

[0463] If the first information uniformly indicates a second time-domain offset O (mode B-2), this second time-domain offset O represents the end-time domain unit of the first of the M end-time domain units among the M end-time domain units of the sensing resource sets after the second time-domain offset O following the time-domain unit where the first information is located. Taking the first time-domain offset L indicating the first sensing resource set as an example, that is, the sensing resource set corresponding to this first end-time domain unit is the first sensing resource set.

[0464] Optionally, the first information may also indicate the first temporal offset L of the M sets of sensing resources. m and / or second time-domain offset O m Where m is an integer, and can take the values ​​m = 1, 2, ..., M or m = 0, 1, ..., M-1.

[0465] For example, the first information can indicate the first temporal offset L of the sensing resource set m. m This refers to the first temporal offset of each of the M sensing resource sets. This first temporal offset L... m The starting temporal unit of the sensing resource set m represents the first temporal unit of the sensing resource set m after the first temporal offset L following the temporal unit where the first information is located.

[0466] The first information can indicate the second temporal offset O of the sensing resource set m. m This refers to the second time-domain offset of each of the M sensing resource sets. This second time-domain offset O... m The terminator represents the end domain unit of the first end domain unit of the sensing resource set m after the second time domain offset O following the time domain unit where the first information is located.

[0467] The above describes the content of the temporal resources of the sensing resource set indicated by the first information. Optionally, the first device, the second device, the third device, the fourth device, and other devices receiving the first information can determine the temporal resources of the sensing resource set based on the content indicated by the first information. For example, the temporal resources of the sensing resource set can be determined based on at least two of the following: the sensing resource set period, the starting temporal unit information of the sensing resource set (i.e., the first parameter), the ending temporal unit information of the sensing resource set (i.e., the second parameter), and the number of sensing resource sets M. Specifically, the determination methods of the sensing resource set period, the starting temporal unit information of the sensing resource set (the first parameter), the ending temporal unit information of the sensing resource set (the second parameter), and the number of sensing resource sets M are as described above. Any method can be used, or other methods outside of this application, and this application does not impose any restrictions.

[0468] In one possible approach, the first information may also indicate the frequency domain resources of the sensing resource set. The first information may directly indicate the frequency domain resources of the sensing resource set, or it may indirectly indicate the sensing resource set by indicating the frequency domain resources of the sensing resources.

[0469] The following describes five ways to directly indicate the frequency domain resources of a set of sensing resources.

[0470] In Method A, the first information can indicate the starting frequency domain unit of the sensing resource set and the number of frequency domain units in the sensing resource set.

[0471] In Method B, the first information can indicate the starting frequency domain unit of the sensing resource set, the number of frequency domain units in the sensing resource set, and the frequency domain spacing between every two frequency domain units in the sensing resource set.

[0472] In method C, the first information can indicate the starting frequency domain unit and the ending frequency domain unit of the sensing resource set.

[0473] In method D, the first information can indicate the starting frequency domain unit and the frequency domain width of the sensing resource set.

[0474] In method E, the first information can indicate the end frequency domain unit of the sensing resource set and the frequency domain width of the sensing resource set.

[0475] The following introduces three ways to indirectly indicate the frequency domain resources of a set of perceived resources.

[0476] In method F, the first information can indicate the number of frequency domain units of the sensing resources within the sensing resource set. Optionally, the third device can also send a sixth information, which indicates the frequency domain spacing between every two frequency domain units of the sensing resources.

[0477] In method G, the first information can indicate the number of frequency domain units of the sensing resources within the sensing resource set and the frequency domain spacing between every two frequency domain units of the sensing resources.

[0478] In mode H, the first information can indicate the frequency domain spacing between every two frequency domain units of the sensing resource. Optionally, the third device can also send a fifth information, which indicates the number of frequency domain units of the sensing resources within the set of sensing resources.

[0479] In methods F to H described above, the frequency domain resources of the sensing resource set can be determined based on the number of frequency domain units in the sensing resource set and the number of frequency domain units of the sensing resources within the sensing resource set. The relationship between the number of frequency domain units in the sensing resource set, the number of frequency domain units of the sensing resources within the sensing resource set, and the frequency domain resources of the sensing resource set satisfies any one of the following: D = F·E, D m =F m ·E, D = F m ·E m D m =F m ·E m D = E, D m =E m The specific meanings of the parameters can be found in the previous descriptions, and will not be repeated here.

[0480] For example, taking a first set of sensing resources as an example, the first information can indicate the frequency domain resources of the first set of sensing resources in any of the following ways:

[0481] The first information indicates at least two of the following: the starting frequency domain unit of the first sensing resource set, the ending frequency domain unit of the first sensing resource set, or the number of frequency domain units included in the first sensing resource set;

[0482] Alternatively, the first information indicates the starting frequency domain unit of the first sensing resource set, the number of frequency domain units included in the first sensing resource set, or the number of frequency domain units between adjacent frequency domain units in the first sensing resource set.

[0483] Alternatively, the first information indicates at least two of the following: the starting frequency domain unit of the first sensing resource set, the ending frequency domain unit of the first sensing resource set, or the frequency domain width of the first sensing resource set;

[0484] Alternatively, the first information indicates the number of frequency domain units of the first sensing resource;

[0485] Alternatively, the first information indicates the number of frequency domain units of the first sensing resource and the number of frequency domain units between adjacent frequency domain units in the first sensing resource.

[0486] The first information can also indicate the initial frequency domain unit of the sensing resource set; for example, the first information can indicate the value H of the second parameter of the sensing resource set m. m Taking the first set of sensory resources, m, as an example, the first information can indicate that the value of the second parameter of the first set of sensory resources is H. a Taking the second set of sensory resources, m, as an example, the first information can indicate that the value of the second parameter of the second set of sensory resources is H. b .

[0487] Optionally, the sensing configuration end can indicate the number M of the sensing resource set through the first information. For example, the first information can directly indicate the number M of the sensing resource set. Or, for another example, it can be indicated through H in the first information. m The number of elements indicates the number M of the sensing resource set. For example, this can be determined through the first information D. m The number of elements indicates the number M of the sensing resource sets. This method is applicable to scenarios where M sets of sensing resources correspond to the number of frequency domain units in each set. For example, it can be determined through E in the first information. m The number of elements indicates the number M of the sensing resource sets. This method is applicable to scenarios where the frequency domain units of each of the M sensing resource sets correspond to a certain number of sensing resources. For example, it can be determined through F in the first information. m The number of indicators M represents the number of sensing resource sets. This method can be applied to scenarios where the frequency domain spacing between every two frequency domain units corresponds to the M sets of sensing resources.

[0488] In another implementation, the first information can indicate the second parameter H or H m .

[0489] For example, the first information indicates the value H of the second parameter. That is, the first information indicates one second parameter, and the value of the second parameter is H. The set of perceptual resources indicated by the first information is the single set of perceptual resources.

[0490] For example, the first information indicates the value H of the second parameter. The second parameter indicates the information of the starting frequency domain unit of the first sensing resource set. The first sensing resource set includes information from frequency domain unit f. m The initial D frequency domain units, where frequency domain unit f m Satisfy f m mod(D) = H. Where D is the number of frequency domain units included in the first sensing resource set.

[0491] For example, the first information indicates the value H of the second parameter and the number M of the sensory resource sets. That is, the first information indicates one second parameter, and the value of the second parameter is H. Among them, the second parameter of the M sensory resource sets has the same value, which is H. The sensory resource sets indicated by the first information include {sensory resource set 1, sensory resource set 2, ..., sensory resource set m, ..., sensory resource set M}.

[0492] For example, the first information indicates the value H of the second parameter. The second parameter indicates information about the starting frequency domain unit of the first sensing resource set and information about the starting frequency domain unit of the second sensing resource set. The first sensing resource set includes information from frequency domain unit f. m The initial D1 frequency domain units, where frequency domain unit f m Satisfy f m mod(D1) = H. The second set of sensory resources includes data from frequency domain unit f. m The initial D2 frequency domain units, where frequency domain unit f m Satisfy f m mod(D2) = H. D1 and D2 can be the same or different; this example does not impose any restrictions.

[0493] For example, the first information indicates the values ​​H of the M second parameters. m That is, the first information indicates M second parameters, and the values ​​of the M second parameters are respectively H. m (m = 1, 2, ..., M). This can be determined by the second parameter H. m The number of elements determines the number M of the sensory resource set. The sensory resource set indicated by the first information includes {sensory resource set 1, sensory resource set 2, ..., sensory resource set m, ..., sensory resource set M}.

[0494] For example, the first information indicates the values ​​H1 and H2 of the two second parameters. m If the number of elements is 2 (i.e., H1 and H2), then the first information indicates M = 2 sets of sensing resources. H1 and H2 indicate the information of the starting frequency domain units of the first and second sensing resource sets, respectively. The first sensing resource set includes information from frequency domain unit f. m The initial D1 frequency domain units, where frequency domain unit f m Satisfy f m mod(D1) = H1. The second set of sensory resources includes those from frequency domain unit f. m The initial D2 frequency domain units, where frequency domain unit f m Satisfy f m mod(D2) = H2. D1 and D2 can be the same or different; this example does not impose any restrictions.

[0495] The above implementation methods can be combined. For example, the first information can indicate the number of frequency domain units in the sensing resource set and the second parameter. As another example, the first information can indicate the number of frequency domain units in the sensing resource, the frequency domain spacing between every two frequency domain units of the sensing resource, and the second parameter. And so on.

[0496] For example, the first piece of information could indicate D, H1, and H2. m If the number of elements is 2 (i.e., H1 and H2), then the first information indicates M = 2 sets of sensing resources. Here, D indicates the number of frequency domain units included in the first and second sensing resource sets, and H1 and H2 respectively indicate the information of the starting frequency domain units of the first and second sensing resource sets. The first sensing resource set includes elements starting from index f. m A set of D RBs starting with RE, where index f m Satisfy f m mod(D) = H1. The second set of sensory resources includes those from time slot f. m A set of D RBs starting with RE, where index f m Satisfy f m mod(D) = H2.

[0497] The first piece of information can indicate D1, D2, H1, and H2. m The number of H is 2 (i.e., D1 and D2). m If the number of elements is 2 (i.e., H1 and H2), then the first information indicates M = 2 sets of sensing resources. D1 and D2 represent the number of RBs in the first and second sensing resource sets, respectively, and G1 and G2 indicate the information of the starting frequency domain units of the first and second sensing resource sets, respectively. The first sensing resource set includes elements starting from index f... m The set of D1 RBs starting with RE, where index f m Satisfy f m mod(D1) = H1. The second set of sensory resources includes those from time slot f. m The set of D2 RBs starting with RE, where index f m Satisfy f m mod(D2) = H2.

[0498] The first information can indicate E, F, H1, and H2. H mIf the number of elements is 2 (i.e., H1 and H2), then the first information indicates M = 2 sets of sensing resources. Here, E indicates the number of frequency domain units included in the sensing resources of the first and second sets, F indicates the frequency domain interval between every two frequency domain units in the first and second sets, and H1 and H2 respectively indicate the information of the starting frequency domain units of the first and second sets. Based on E and F, the number D of frequency domain units included in the first and second sets can be determined. The first set includes elements starting from index f. m A set of D RBs starting with RE, where index f m Satisfy f m mod(D) = H1. The second set of sensory resources includes those from time slot f. m A set of D RBs starting with RE, where index f m Satisfy f m mod(D) = H2.

[0499] The first information can indicate E1, E2, F1, F2, H1, and H2. F m The number of elements is 2 (i.e., F1, F2), E m The number of H is 2 (i.e., E1, E2). m If the number of elements is 2 (i.e., H1 and H2), then the first information indicates M = 2 sets of sensing resources. E1 and E2 indicate the number of frequency domain units included in the sensing resources of the first and second sets of sensing resources, respectively; F1 and F2 indicate the frequency domain interval between every two frequency domain units in the first and second sets of sensing resources, respectively; and H1 and H2 indicate the information of the starting frequency domain units of the first and second sets of sensing resources, respectively. Based on E1 and F1, the number of frequency domain units D1 included in the first set of sensing resources can be determined, and based on E2 and F2, the number of frequency domain units D2 included in the first set of sensing resources can be determined. The first set of sensing resources includes elements starting from index f... m The set of D1 RBs starting with RE, where index f m Satisfy f m mod(D1) = H1. The second set of sensory resources includes those from time slot f. m A set of D RBs starting with RE, where index f m Satisfy f m mod(D2) = H2.

[0500] The first information can indicate E, F1, F2, H1, and H2. F m The number of H is 2 (i.e., F1, F2). mIf the number of elements is 2 (i.e., H1 and H2), then the first information indicates M = 2 sets of sensing resources. Here, E indicates the number of frequency domain units included in the sensing resources of the first and second sets of sensing resources; F1 and F2 indicate the frequency domain interval between every two frequency domain units in the first and second sets of sensing resources, respectively; and H1 and H2 indicate the information of the starting frequency domain units of the first and second sets of sensing resources, respectively. Based on E and F1, the number of frequency domain units D1 included in the first set of sensing resources can be determined, and based on E and F2, the number of frequency domain units D2 included in the second set of sensing resources can be determined. The first set of sensing resources includes elements starting from index f... m The set of D1 RBs starting with RE, where index f m Satisfy f m mod(D1) = H1. The second set of sensory resources includes those from time slot f. m A set of D RBs starting with RE, where index f m Satisfy f m mod(D2) = H2.

[0501] The first information can indicate E1, E2, F, H1, and H2. E m The number of H is 2 (i.e., E1, E2). m If the number of elements is 2 (i.e., H1 and H2), then the first information indicates M = 2 sets of sensing resources. E1 and E2 indicate the number of frequency domain units included in the sensing resources of the first and second sets, respectively; F indicates the frequency domain interval between every two frequency domain units in the first and second sets; and H1 and H2 indicate the information of the starting frequency domain units of the first and second sets, respectively. Based on E1 and F, the number of frequency domain units D1 included in the first set can be determined, and based on E2 and F, the number of frequency domain units D2 included in the second set can be determined. The first set of sensing resources includes elements starting from index f. m The set of D1 RBs starting with RE, where index f m Satisfy f m mod(D1) = H1. The second set of sensory resources includes those from time slot f. m A set of D RBs starting with RE, where index f m Satisfy f m mod(D2) = H2.

[0502] As described above, the first information can indicate at least one of the following: the temporal starting information G of the set of sensed resources. m Perceived resource set period P1 or P1 mThe initial time-domain unit of the sensing resource set, the final time-domain unit of the sensing resource set, and the number of sensing resources C or C0 within the sensing resource set. m Perceived resource cycle P2 or P2 m The number of cycles in the perception resource set Y or Y m The first field is either K1 or K2 or K1 m or K2 m First time-domain offset L or L m Second time-domain offset O or O m Frequency domain initial information H of the sensing resource set m The number of frequency domain units D or Di included in the sensing resource set. m The starting frequency domain unit of the sensing resource set, the ending frequency domain unit of the sensing resource set, and the frequency domain width I or I of the sensing resource set. m The frequency domain spacing J or J0 between every two frequency domain units in the sensing resource set m The number of frequency domain units E or E0 of the sensing resources within the sensing resource set. m The frequency domain spacing F or F between every two frequency domain units of the sensing resource m The parameters are: the number of sensing resource sets M, the periodic repetition information of the sensing resource sets, a first power adjustment value, or a second power adjustment value. The periodic repetition information of the sensing resource sets is the start time-domain unit and / or the end time-domain unit of the sensing resource sets. The first information indicates the first field, or it can be described as the first information indicating the start time-domain unit information and / or the end time-domain unit information of the sensing resource sets.

[0503] The above information can be directed to a single set of sensing resources or to M sets of sensing resources. For example, taking the first information indicating periodic repetition as an example, the first information can instruct a single set of sensing resources, such as the first set of sensing resources, to repeat periodically, or it can instruct M sets of sensing resources to repeat periodically. Specific methods can be found in methods 1 and 2 above. It should be noted that methods 1 and 2 use a single set of sensing resources as an example. If M sets of sensing resources are instructed, the first information can use a similar method to instruct the M sets of sensing resources. Understandably, as described above, the M sets of sensing resources can correspond to a single parameter value for a given parameter, or they can correspond to individual parameter values, such as the period of the sensing resource set, the period of the sensing resources, the number of sensing resources, the number of frequency domain units in the sensing resource set, etc. Therefore, in scenarios where one parameter corresponds to one parameter value for M sets of sensing resources, the first information can be uniformly configured for all M sets of sensing resources. In scenarios where one parameter corresponds to one parameter value for each of the M sets of sensing resources, the first information can be configured separately for each of the M sets of sensing resources. The specific indication methods can be combined with the relevant descriptions of each parameter above, and will not be explained in detail here.

[0504] In this application, the first information can be configured or pre-configured, or the content of the first information indicating the first information can be configured or pre-configured. For example, the first information can be sent by a third device to a first device, a second device, or a fourth device. In this method, the third device is a different device from the first device, the second device, or the fourth device. For example, the third device can be a network device. Alternatively, the first information can be sent by the first device to the second device or the fourth device, that is, the third device and the first device are the same device. In this method, the first device does not need to receive the first information but can directly obtain it. Alternatively, the first information can also be sent by the fourth device to the first device and the second device, that is, the third device and the fourth device are the same device. In this method, the fourth device does not need to receive the first information but can directly obtain it.

[0505] The first information can be preset, or a portion of the content indicated by the first information can be preset. For example, it can be preset by the protocol. In this method, S401 and S402 can be omitted.

[0506] The first piece of information can be semi-static or dynamically activated and deactivated.

[0507] Method 1: The first information can be carried by RRC or MAC CE.

[0508] For example, the first piece of information is carried by a MAC CE, and the LCID of the MAC subheader of this MAC CE can be a fourth value. This MAC CE can indicate the configuration (reconfiguration) of a set of awareness resources. The fourth value can be any integer from 35 to 46.

[0509] For example, the first information is carried by a MAC CE, and the LCID of the MAC subheader of this MAC CE can be a fifth value. This MAC CE can indicate the release of a set of sensing resources. The fifth value can be any integer from 35 to 46.

[0510] Method 2: The first information can be carried by DCI or SCI.

[0511] For example, the first field included in the DCI or SCI can be used to indicate the dynamic activation of the sensing resource set. As another example, the sensing resource set can be activated using the first field included in the DCI or SCI. For details, please refer to the relevant descriptions above; they will not be repeated here.

[0512] In this application, the first information can be scrambled by a first RNTI. The first RNTI can be an RNTI used for sensing or an RNTI specifically for sensing. That is, the first device, the second device, and the fourth device can all decode the first information using the first RNTI.

[0513] In this application, activation can be understood as starting, enabling, configuring, etc., and these terms can be used interchangeably. Deactivation can be understood as ending, disabling, releasing, etc., and these terms can be used interchangeably.

[0514] S402, the third device sends the first information. Correspondingly, the first device receives the first information.

[0515] The first information is used to configure the first set of sensing resources, which includes periodically repeating first sensing resources.

[0516] Optionally, as described above, the second device may also receive the first information, and the first information may also configure the second device with a first set of sensing resources.

[0517] Optionally, the second device may also receive the first information. For example, if the first device and the fourth device are different devices, the fourth device may receive the aforementioned first information before receiving the first sensing signal on the first sensing resource.

[0518] S403, the first device transmits a first sensing signal on the first sensing resource. Correspondingly, the fourth device receives the first sensing signal on the first sensing resource.

[0519] The first sensing signal is used to determine information about the sensing target. This determination of the sensing target information can also be referred to as operating sensing services, or simply as performing sensing.

[0520] The information of the perceived target includes at least one of the following: motion information of the perceived target, motion change information of the perceived target, distance information of the perceived target, velocity information of the perceived target, and angle information of the perceived target. In other words, determining the information of the perceived target can be replaced by determining at least one of the following: motion information, motion change information, distance information, velocity information, and angle information.

[0521] The first device sends a first sensing signal, and the third device receives and / or processes the first sensing signal. The first sensing signal is used to determine information about the sensing target. It is understood that the third device processes the first sensing signal to determine information about the sensing target, and the first sensing signal sent by the first device is to enable the third device to determine information about the sensing target.

[0522] As described above, the first information can also configure the second device with a first set of sensing resources. Therefore, the second device can also send a second sensing signal on the first set of sensing resources. The second sensing signal is used to determine information about the sensing target, or, alternatively, the second sensing signal is used to assist in determining information about the sensing target. It can be understood that the third device can determine information about the sensing target by processing the second sensing signal, and the second sensing signal sent by the second device is intended to enable the third device to determine information about the sensing target, or in other words, the second sensing signal sent by the second device is intended to assist the third device in determining information about the sensing target.

[0523] Optionally, the fourth device may receive the second sensing signal on the first sensing resource. It can be understood that the fourth device receives the sum of the first and second sensing signals. That is, the sum of the first and second sensing signals can be used to determine information about the sensing target.

[0524] Optionally, if the first device and the fourth device are the same equipment, then the first device and / or the fourth device can directly determine the aforementioned first information.

[0525] Optionally, if the first device and the fourth device are different devices, the fourth device may receive the aforementioned first information before receiving the first sensing signal on the first sensing resource. For example, it may receive the first information from the first device or the third device.

[0526] Optionally, the second device may also receive the aforementioned first information before sending the second sensing signal on the first sensing resource. For example, it may receive the first information from the first device or the third device.

[0527] In one possible implementation, the first device may specifically transmit a first sensing signal on each of the first sensing resources included in the first sensing resource set. In this implementation, each of the first sensing resources included in the first sensing resource set carries a sensing signal. Alternatively, it can be described that within the first sensing resource set, the first device begins transmitting the first sensing signal at the start time domain unit of the first sensing resource and continues until the end time domain unit of the first sensing resource. It can also be described that the first sensing signal is transmitted at the time domain unit where each of the first sensing resources included in the first sensing resource set is located.

[0528] The first device can send a first sensing signal on each of the first sensing resources included in the first sensing resource set when it is necessary to send a sensing signal or to perform a sensing service.

[0529] In another possible implementation, the first device may specifically transmit a first sensing signal on each first sensing resource included within a first time period. In this implementation, each first sensing resource included within the first time period carries a sensing signal.

[0530] The first device can send a first sensing signal on each first sensing resource included in the first time period when it is necessary to send a sensing signal or to perform a sensing service.

[0531] In another possible implementation, the first device may specifically transmit a first sensing signal on each of the first sensing resources included in at least one cycle of a periodically repeating first set of sensing resources. In this implementation, each of the first sensing resources included in at least one cycle of the periodically repeating first set of sensing resources carries a sensing signal.

[0532] The first device may transmit a first sensing signal on each of the first sensing resources included in at least one cycle of a periodically repeating first sensing resource set when it is necessary to transmit a sensing signal or to perform a sensing service.

[0533] One example is that the first device may transmit a first sensing signal on each of the first sensing resources included in the first H cycles of the periodically repeating first sensing resource set, that is, each of the first sensing resources included in the first H cycles of the first sensing resource set carries a sensing signal. For example, assuming that the first device repeats the cycle 3 times, the first device may transmit the first sensing signal on each of the first sensing resources included in the first and second cycles of the first sensing resource set, that is, each of the first sensing resources included in the first and second cycles of the first sensing resource set carries a sensing signal.

[0534] In the above three embodiments, the first sensing signal is transmitted on each of the first sensing resources included in the first sensing resource set, or the first sensing signal is transmitted on the time domain unit where each of the first sensing resources included in the first sensing resource set is located. It can also be understood that the sensing signal transmission on any first sensing resource is not discarded when the first sensing resource set includes the first sensing resources, or in other words, the sensing signal transmission on any first sensing resource is not expected to be discarded.

[0535] It is understood that the first set of sensing resources includes the first sensing resources and other resources. The first device may not transmit signals to the other resources; for example, it may not transmit the first sensing signal.

[0536] Within the set of sensing resources, the first device and / or the second device begin transmitting sensing signals at the start time domain unit of the sensing resource and continue until the end time domain unit of the sensing resource. It can be understood that sensing signals are transmitted at non-start time domain units of sensing resources not within the set of sensing resources, and transmission of sensing signals ceases at non-end time domain units of sensing resources not within the set of sensing resources.

[0537] Sending a first sensing signal on each of the first sensing resources included in at least one cycle of the periodically repeating first sensing resource set can be understood as sending a first sensing signal at the beginning time domain unit of each first sensing resource within at least one cycle of the periodically repeating first sensing resource set until the end time domain unit of each first sensing resource.

[0538] It should be noted that the above three implementation methods are the desired ways of sending sensing signals. In specific implementations, the first device may not be able to occupy each of the above sensing resources when sending sensing signals. For example, one or more sensing resources may be occupied by other devices, etc. This application does not exclude the occurrence of these situations.

[0539] Optionally, the third device may enable the first device to skip the transmission of first sensing signals on one or more of the first sensing resources in the first sensing resource set. For example, when the number of candidate communication signals to be transmitted and / or the number of candidate sensing signals to be transmitted by the first device is greater than or equal to the maximum concurrency, the first device may skip the transmission of first sensing signals on one or more of the first sensing resources in the first sensing resource set. Here, candidate communication signals to be transmitted can also be understood as communication signals to be transmitted, and candidate sensing signals to be transmitted can also be understood as sensing signals to be transmitted.

[0540] Furthermore, the first and second devices can transmit sensing signals on the same resources, thereby increasing the signal-to-noise ratio of the received sensing signals by the first device. In other words, the second device assists the first sensing transmitter in transmitting sensing signals. This helps to expand the sensing coverage area and increase the reliability of sensing.

[0541] Optionally, during the second time period, the transmission power of the first device transmitting the first sensing signal on the first sensing resource remains constant. Alternatively, it can be described that during the second time period, the first device transmits the sensing signal on the first sensing resource at the same transmission power. For other sets of sensing resources (such as the periodic repetition of the first sensing resource set), the transmission power of the first device transmitting the sensing signal on the sensing resource can vary or remain constant; that is, the transmission power of the first device can vary or remain constant between different sets of sensing resources.

[0542] Transmitting the first sensing signal at the same transmission power includes: when transmitting the first sensing signal on each first sensing resource within the first sensing resource set, the first device transmits the first sensing signal using the same at least one of the following parameters: the same P0 parameter, the same path loss compensation factor α, the same path loss estimate PL, and the same maximum transmit power P. CMAX Here, P0 is the P0 parameter used for power control, which can be understood as the initial value of the uplink transmit power, and is essentially the desired receive power.

[0543] Alternatively, when the first device transmits a first sensing signal in the time domain unit where each first sensing resource in the first sensing resource set resides, the first device uses the same at least one of the following parameters in the time domain unit where each first sensing resource resides: the same P0 parameter, the same path loss compensation factor α, the same path loss estimate PL, and the same maximum transmit power P. CMAX .

[0544] Optionally, during the second time period, the transmission power of at least two sensing transmitters transmitting sensing signals on the first sensing resource set remains constant. One example is that the transmission power of each sensing transmitter transmitting sensing signals on the first sensing resource set remains constant. For instance, the transmission power of the first device and the second device transmitting the first sensing signal on the first sensing resource remains constant. Alternatively, it can be described that during the second time period, each sensing transmitter (e.g., the first device and the second device) transmits sensing signals on the first sensing resource at the same transmission power. For other sensing resource sets (such as periodic repetition of the first sensing resource set), the transmission power of the sensing transmitters transmitting sensing signals on the sensing resource can vary or remain constant; that is, the transmission power can vary or remain constant between different sensing resource sets.

[0545] Transmitting the first sensing signal at the same transmission power includes: when transmitting the first sensing signal on each first sensing resource within the first sensing resource set, the first device and the second device transmit the first sensing signal using at least one of the following parameters: the same P0 parameter, the same path loss compensation factor α, the same path loss estimate PL, and the same maximum transmit power P. CMAX Here, P0 is the P0 parameter used for power control, which can be understood as the initial value of the uplink transmit power, and is essentially the desired receive power.

[0546] Alternatively, when transmitting a first sensing signal in the time-domain unit where each first sensing resource in the first sensing resource set resides, the first device and the second device use the same at least one of the following parameters in the time-domain unit where each first sensing resource resides: the same P0 parameter, the same path loss compensation factor α, the same path loss estimate PL, and the same maximum transmit power P. CMAX .

[0547] Accordingly, the sensing receiver can determine that the transmission power of the sensing signal of each sensing transmitter (e.g., the first device and the second device) on the first sensing resource set remains constant during the second time period.

[0548] Assuming a first device and a second device transmit sensing signals on a first set of sensing resources, and both devices maintain a constant transmission power (e.g., 100 dBm), when a third device receives a changing sensing signal (e.g., 80–85 dBm), it can determine that the change in signal power is due to factors such as the movement of the sensing target, and thus determine the information of the sensing target based on this change. Conversely, if the transmission power of the second device changes, the fourth device cannot determine whether the change in the received sensing signal is caused by the movement of the sensing target or by the second device, which would affect the accuracy and reliability of the sensing results. This method ensures that the only influencing factors on the changes in the sensing signal within the first time period Tw or the first set of sensing resources are factors such as the movement of the sensing target. This avoids interference between different sensing transmitters.

[0549] In another possible approach, during the second time period, at least two sensing transmitters (e.g., the first device and the second device) exhibit the same change in transmission power when transmitting sensing signals on the first sensing resource set. One example is that each sensing transmitter (e.g., the first device and the second device) exhibits the same change in transmission power when transmitting sensing signals on the first sensing resource set. For instance, both the first device and the second device transmit a first sensing signal on the first sensing resource, and the change in transmission power of the first device transmitting the first sensing signal on the first sensing resource is the same as the change in transmission power of the second device transmitting a second sensing signal on the first sensing resource. That is, the transmission power of the first device and the second device within the first sensing resource set may differ, but the change in transmission power is the same.

[0550] The first device and the second device transmit sensing signals on the same first sensing resource. That is, the first device and the second device transmit sensing signals on the same first sensing resource within the same set of first sensing resources. For example, the first device transmits first sensing signals on first sensing resources in the fourth time domain unit and first sensing resources in the fifth time domain unit. The second device transmits second sensing signals on first sensing resources in the fourth time domain unit and first sensing resources in the fifth time domain unit. The first device transmits first sensing signals with different transmission powers on different first sensing resources; that is, the first device transmits first sensing signals with different transmission powers in the fourth and fifth time domain units. Correspondingly, the second device also transmits second sensing signals with different transmission powers in the fourth and fifth time domain units.

[0551] The first power adjustment value of the first device is the same as the second power adjustment value of the second device. Specifically, the first power adjustment value is the change in the transmission power of the sensing signal transmitted by the first device in the fourth and fifth time domain units, and the second power adjustment value is the change in the transmission power of the sensing signal transmitted by the second device in the fourth and fifth time domain units. More specifically, the first power adjustment value can be the change in the transmission power of the sensing signal transmitted by the first device on the first sensing resource in the fourth and fifth time domain units, and the second power adjustment value can be the change in the transmission power of the sensing signal transmitted by the second device on the first sensing resource in the fourth and fifth time domain units.

[0552] The fourth and fifth time-domain units are two time-domain units within the set of perceived resources, where the perceived resources are located. For example, they are two adjacent or spaced-apart time-domain units.

[0553] For example, the first power adjustment value of the transmission power of the first device on the second first sensing resource relative to the transmission power on the first first sensing resource is X dB, and the second power adjustment value of the transmission power of the second device on the second first sensing resource relative to the transmission power on the first first sensing resource also needs to be X dB.

[0554] For example, if the first power adjustment value of the transmission power of the first device in the fifth time domain unit compared to the transmission power in the fourth time domain unit is X dB, the first power adjustment value of the transmission power of the second device in the fifth time domain unit compared to the transmission power in the fourth time domain unit also needs to be X dB.

[0555] The first power adjustment value may include any one of the following: transmit power adjustment value, maximum transmit power P. CMAX The adjustment values ​​include: P0 parameter adjustment value, path loss compensation factor α adjustment value, and path loss estimate PL adjustment value. Similarly, the second power adjustment value may include any one of the following: transmit power adjustment value, maximum transmit power P... CMAX Adjustment values, P0 parameter adjustment values, path loss compensation factor α adjustment values, and path loss estimate PL adjustment values.

[0556] The first power adjustment value and the second power adjustment value are the same, which can be understood as: the transmit power adjustment value is the same, and the maximum transmit power P is the same. CMAX The adjustment values ​​are the same, the adjustment values ​​for the P0 parameter are the same, the adjustment values ​​for the path loss compensation factor α are the same, and the adjustment values ​​for the path loss estimate PL are the same.

[0557] The second device can adjust its transmission power according to a first power adjustment value, meaning the change in the transmission power of the sensing signal transmitted by the second device in the fourth and fifth time domain units is equal to the first power adjustment value. The first power adjustment value can be indicated by first information or by the first device through third information. The first or third information indicates the change in the transmission power of the first sensing signal or indicates the change in the transmission power of sensing signals transmitted by other sensing transmitters. The first device can send the third information to other sensing transmitters, such as the second device or the fourth device. Alternatively, the first device can send the third information to a network device (e.g., the third device), and the network device (e.g., the third device) indicates the change in the transmission power of the sensing signal transmitted on the first sensing resource to other sensing transmitters, such as the second device or the fourth device.

[0558] Alternatively, the first device can adjust its transmission power according to the second power adjustment value, that is, the change in the transmission power of the first device transmitting the sensing signal in the fourth time domain unit and the fifth time domain unit is equal to the second power adjustment value.

[0559] Alternatively, the second power adjustment value can be indicated by the first information or by the second device through a fourth information. The first or fourth information indicates a change in the transmission power of the second sensing signal or indicates a change in the transmission power of sensing signals transmitted by other sensing transmitters. The second device can send the fourth information to other sensing transmitters, such as the first device or the fourth device. Alternatively, the second device can send the fourth information to a network device (e.g., a third device), which in turn indicates to other sensing transmitters, such as the first device or the fourth device, a change in the transmission power of the sensing signal transmitted on the first sensing resource.

[0560] Accordingly, the fourth device can determine that the change in transmission power of each sensing transmitter transmitting sensing signals on the first sensing resource set is the same during the second time period. Optionally, the change in transmission power of each sensing transmitter transmitting sensing signals on the first sensing resource set can be determined based on the aforementioned third information.

[0561] Accordingly, the fourth device can determine the information of the sensed target based on the first power adjustment value. For example, the fourth device can remove the portion of the sensed signal that causes the first power adjustment value to change during signal processing based on the first power adjustment value indicated by the first information or the third information, thereby determining the information of the sensed target.

[0562] Suppose two sensing transmitters (a first device and a second device) transmit sensing signals on a first sensing resource set, and the transmission power of these two transmitters varies in the same way. For example, if the transmission power of both transmitters remains constant in the fourth time domain unit (e.g., both are 100 dBm), the fourth device receives a changed sensing signal (e.g., 80–85 dBm); if the transmission power of both transmitters in the fifth time domain unit is 50 dBm, the fourth device receives a changed sensing signal (e.g., 30–35 dBm). It can be determined that the change in sensing signal from 80–85 dBm to 30–35 dBm is due to the changes in transmission power of the first device in the fourth and fifth time domain units, and the changes in transmission power of the second device in the fourth and fifth time domain units. It can also be determined that the change in sensing signal from 85–80 = 5 dB (and 35–30 = 5 dB) is caused by factors such as the movement of the sensing target, and the information of the sensing target can be determined based on the change in sensing signal. The above method can eliminate the influence of changes in the transmission power of the sensing transmitter, thus ensuring that the only factors affecting the change in the sensing signal within the first time period Tw are factors such as the movement of the sensing target. This avoids the influence of different sensing transmitters on each other's sensing.

[0563] For example, the second time period is the temporal resource of the first set of sensory resources, or it is the temporal resource of the first set of sensory resources that repeats periodically.

[0564] For example, the temporal resources of the first set of sensory resources overlap with the second time period; for instance, the second time period may be equal to the temporal resources of the first set of sensory resources. Alternatively, the second time period includes the temporal resources of the first set of sensory resources; for instance, the second time period is an integer multiple of the temporal resources of the first set of sensory resources. Or, the temporal resources of the first set of sensory resources include the second time period; for instance, the temporal resources of the first set of sensory resources are an integer multiple of the second time period.

[0565] For example, the first time period and the second time period overlap; for instance, the second time period may be equal to the first time period. Alternatively, the second time period may include the first time period; for instance, the second time period may be an integer multiple of the first time period. Or, the first time period may include the second time period; for instance, the first time period may be an integer multiple of the second time period.

[0566] Based on the above scheme, the sensing transmitter, such as the first device, the second device, or other sensing transmitters, or the fourth device, can determine the set of sensing resources to be used based on the starting time domain unit of the M sets of sensing resources.

[0567] As described in S401, the first information can indicate M sets of sensing resources. Therefore, the sensing transmitter, such as the first device, the second device, or other sensing transmitters, or the fourth device, can determine the set of sensing resources it uses from the M sets of sensing resources. The following describes the method of determining the first set of sensing resources using the first device as an example.

[0568] The first set of sensing resources is the set of sensing resources with the earliest starting time domain unit among the M sets of sensing resources. In other words, the sensing signal is sent to the sensing resource set whose starting time domain unit is closest to the first set of sensing resources. Alternatively, the first set of sensing resources is the set of sensing resources containing the sensing resource with the earliest starting time domain unit among the M sets of sensing resources. In other words, the sensing signal is sent to the set of sensing resources containing the sensing resource whose starting time domain unit is closest to the first set of sensing resources.

[0569] Example 1: After the first set of sensory resources becomes the third time domain unit, the earliest sensory resource set among the M sets of sensory resource sets with the earliest starting time domain unit; it can also be described as the sensory resource set corresponding to the earliest starting time domain unit among the M sets of sensory resource sets with the earliest starting time domain unit after the first set of sensory resources becomes the third time domain unit.

[0570] Example 2: After the first set of sensing resources becomes the third time domain unit, the set of sensing resources included in the M sets of sensing resources contains the sensing resource with the earliest starting time domain unit; it can also be described as the set of sensing resources included in the M sets of sensing resources after the first set of sensing resources becomes the third time domain unit, containing the sensing resource with the earliest starting time domain unit.

[0571] In the two examples above, the third time-domain unit is either the time-domain unit that triggers the sensing, or the third time-domain unit is a time-domain unit that is a third time-domain offset after the time-domain unit that triggers the sensing; or the third time-domain unit is related to the time-domain unit that triggers the sensing, or the third time-domain unit is related to both the time-domain unit that triggers the sensing and the third time-domain offset; or the third time-domain unit is the time-domain unit that receives the first information, or the third time-domain unit is a time-domain unit that is a third time-domain offset after the time-domain unit that receives the first information; or the third time-domain unit is related to both the time-domain unit that receives the first information and the third time-domain offset.

[0572] Taking the third time-domain unit as the triggering time-domain unit followed by a third time-domain offset as an example, Example 1 above can also be described as the sensing resource set corresponding to the starting time-domain unit of the first sensing resource set among the M starting time-domain units of the M sensing resource sets after the third time-domain offset Q following the first sensing resource set as the triggering time-domain unit. That is, the first sensing resource set is the sensing resource set corresponding to the starting time-domain unit of the first sensing resource.

[0573] Taking the third time-domain unit as the triggering time-domain unit followed by a third time-domain offset as an example, Example 2 above can also be described as the set of sensing resources corresponding to the starting time-domain unit of the first sensing resource among the M sensing resource sets after the third time-domain offset Q following the first sensing resource set as the triggering time-domain unit. That is, the first sensing resource set is the set of sensing resources corresponding to the starting time-domain unit of that first sensing resource.

[0574] Optionally, the first information may also indicate a third time-domain offset Q. Optionally, the value of the third time-domain offset is equal to the first time-domain offset, or the value of the third time-domain offset is equal to the first time-domain offset by default. The third time-domain offset may include the time for processing the first information, the time for generating the sensing signal, and / or the waiting time, etc.

[0575] Optionally, the third time domain unit can be the first time domain unit, or the third time domain unit can be the first time domain unit by default.

[0576] The first sensing resource set includes the resources that transmit the first sensing signal. That is, the time domain unit of the first sensing resource set includes the time domain unit of the first sensing signal; and / or, the frequency domain unit of the first sensing resource set includes the frequency domain unit of the first sensing signal.

[0577] The above describes a scheme for transmitting sensing signals on a sensing resource set. The following describes the main configuration of the sensing resource set.

[0578] As an optional approach, the first information is used to configure a set of sensing resources for at least one device, for example, to configure M sets of sensing resources. The at least one device includes at least one device that transmits sensing signals (such as a first device, a second device, etc.) and / or at least one device that receives sensing signals (such as a fourth device, etc.).

[0579] Optionally, in this application, a stationary device may transmit a sensing signal on the sensing resource set, and / or a non-stationary device may not transmit a sensing signal on the sensing resource set. Alternatively, a device with a movement speed less than or equal to a first speed may transmit a sensing signal on the sensing resource set, and / or a device with a movement speed greater than or equal to a second speed may not transmit a sensing signal on the sensing resource set, that is, the movement speeds of the first device and the second device are less than or equal to the first speed. Wherein, the first speed is less than or equal to the second speed.

[0580] Accordingly, the third device allocates a set of sensing resources to stationary devices or devices whose moving speed is less than or equal to a first speed. Based on this, the moving speed of at least one device transmitting a sensing signal (such as a first device, a second device, etc.) involved in this application is less than or equal to a threshold value. The threshold value can be 0, meaning that the aforementioned at least one device transmitting a sensing signal (such as a first device, a second device, etc.) is stationary. The threshold value can be a first speed, meaning that the aforementioned at least one device transmitting a sensing signal (such as a first device, a second device, etc.) is a device whose moving speed is less than or equal to a first speed.

[0581] The third device can determine that the device is stationary or that the device's velocity is less than or equal to the first velocity by any of the following four methods:

[0582] Method a: The device that sends the sensing signal (such as the first device, the second device, etc.) and / or the device that receives the sensing signal (such as the fourth device, etc.) reports that its state is stationary or non-stationary.

[0583] Method b: The device that sends the sensing signal (such as the first device, the second device, etc.) and / or the device that receives the sensing signal (such as the fourth device, etc.) reports its status as a speed less than or equal to the first speed or a speed greater than or equal to the second speed.

[0584] Method c: The signal energy of the third device measuring the device that transmits the sensing signal (such as the first device, the second device, etc.) and / or the device that receives the sensing signal (such as the fourth device, etc.) remains unchanged.

[0585] Method d: The variance of the signal energy of the device that transmits the sensing signal (such as the first device, the second device, etc.) and / or the device that receives the sensing signal (such as the fourth device, etc.) is less than the first signal energy threshold.

[0586] The signal energy can be either the reference signal strength indication (RSSI) or the reference signal received power (RSRP) of the sensed signal.

[0587] In method d, the variance of the signal energy of the device transmitting the sensing signal (such as the first device, the second device, etc.) and / or the device receiving the sensing signal (such as the fourth device, etc.) is less than a first signal energy threshold. Specifically, this can be achieved by the variance of the signal energy at the sensing transmitter / sensing receiver being less than the first signal energy threshold during a third time period.
