[0002] The present application claims priority to the Chinese Patent Application No. 202411377306.9, filed on September 29, 2024, and entitled "A sensing method and apparatus", the content of which is incorporated herein by reference in its entirety. TECHNICAL FIELD

[0003] The present application relates to the field of communication technology, and in particular to a sensing method and apparatus. BACKGROUND

[0004] Communication and sensing integration is to integrate wireless communication and sensing functions in the same system, to realize positioning, detection, imaging and identification of targets and other sensing functions by using various propagation characteristics of wireless signals, to obtain surrounding physical environment information, to improve communication performance, and to enhance user experience. In the communication and sensing integration technology, sensing can be performed by using sensing signals to obtain the position, speed and other information of targets in the environment.

[0005] Currently, there is no resource allocation technology for sensing systems, and how to allocate resources in sensing systems becomes a problem to be solved. SUMMARY

[0006] Embodiments of the present application provide a sensing method and apparatus for providing a configuration mode of sensing resources.

[0007] In a first aspect, the present application provides a sensing method, the execution subject of the method is a first apparatus, which can be a first device or a chip or circuit on the side of the first device. The first device can be a network device or a terminal device. The method comprises: receiving first information, the first information being used for configuring a first sensing resource set, the first sensing resource set comprising periodically repeated first sensing resources; and transmitting a first sensing signal on the first sensing resources, the first sensing signal being used for determining information of a sensing target.

[0008] In the present application, a unified configuration mode of sensing resource sets is provided, thereby allowing different sensing transmitting ends (for example, the first apparatus and a second apparatus) to transmit sensing signals on the same sensing resources, and thereby the resource overhead of sensing can be reduced from the system level.

[0009] In addition, since sensing can be continuously performed, in the present application, based on periodically repeated sensing resources, the sensing transmitting end and the sensing receiving end can accumulate sensing signals, thereby improving the accuracy of determining the information of the sensing target.

[0010] In a possible design, the first sensing signal is transmitted on the first sensing resource, including: the first sensing signal is transmitted on each first sensing resource included in the first set of sensing resources; and / or the first sensing signal is transmitted on each first sensing resource included in a first time period, and the first time period is an accumulation duration of the first sensing signal; and / or the first sensing signal is transmitted on each first sensing resource included in at least one period of the first set of sensing resources. It can be understood that the first time period is a time period for accumulation of the sensing signal, for example, the first time period is a time period for accumulation of the first sensing signal.

[0011] By the constraint that the sensing signal is transmitted on each sensing resource in the set of sensing resources, the influence of sudden stop of the sensing device on the sensing accuracy can be reduced. For example, the sensing device does not transmit the sensing signal on the last sensing resource of the set of sensing resources, resulting in a sudden change of the sensing signal, which is easily mistaken as being caused by the movement of the sensing target. For another example, the sensing device starts to transmit the sensing signal on the non-first sensing resource of the set of sensing resources, resulting in a sudden change of the sensing signal, which is easily mistaken as being caused by the movement of the sensing target. However, in this application, the constraint that the sensing signal is transmitted on each sensing resource in the set of sensing resources can avoid the influence of the sudden stop of the sensing signal on the sensing service, and improve the sensing accuracy. Based on the above design, the first device (and / or the second device) transmits the sensing signal on each sensing resource in the set of sensing resources, or the first device (and / or the second device) does not transmit the sensing signal on each sensing resource in the set of sensing resources. The amplitude and / or phase of the signal received on multiple first resources in the set of sensing resources can be changed as little as possible, so as to reduce the influence on the sensing accuracy.

[0012] In a possible design, in the second time period, the transmission power of the first sensing signal transmitted by the first device on the first sensing resource remains unchanged; or in the second time period, the change of the transmission power of the first sensing signal transmitted by the first device on the first sensing resource is the same as the change of the transmission power of the second sensing signal transmitted by the second device on the first sensing resource.

[0013] By the constraint that the transmission power of the sensing signal is constant or changes by the same amount, the impact caused by the change of the transmission power of the sensing signal can be avoided. For example, if the second device stops / transmits the sensing signal halfway through the first time period Tw of the first device, a sudden change of the sensing signal on the first sensing resource will be caused, which is easy to be misjudged as the movement of the sensing target. However, in the present application, the constraint that the transmission power of the sensing signal is constant or changes by the same amount can avoid the impact of the change of the transmission power of the sensing signal on the sensing service, and improve the accuracy of sensing. Based on the above design, the first device (and / or the second device) transmits the sensing signal on the sensing resources in the sensing resource set at the same transmission power, or the first device (and / or the second device) does not transmit the sensing signal on the sensing resources in the sensing resource set. The amplitude and / or phase of the signal received on multiple first resources in the sensing resource set can be changed as much as possible, so as to reduce the impact on the sensing accuracy. Alternatively, if the transmission power of the sensing signal of the first device changes, the fourth device can compensate the impact of the change of the transmission power on the amplitude of the received signal based on the power change value, so as to obtain the part of the target movement affecting the change of the received sensing signal, thereby reducing the impact on the sensing accuracy.

[0014] In a possible design, the third information is transmitted, and the third information is used to indicate the change of the transmission power of the sensing signal transmitted on the first sensing resource. Through the above design, the transmission power of the sensing signal transmitted by different devices can change by the same amount.

[0015] In a possible design, the second time period is the time domain resource of the first sensing resource set. Through the above design, the power of the sensing signal transmitted in the first sensing resource set can be controlled, and correspondingly, the only factor affecting the change of the received sensing signal is the movement of the sensing target.

[0016] In a possible design, the first sensing resource set is periodically repeated. Through the above design, the accumulation time of the sensing signal can be improved, and thus the accuracy of sensing can be improved.

[0017] In a possible design, the first information is used to configure the first sensing resource set for the first device and the second device. Through the above design, multiple devices can transmit the sensing signal on the same sensing resource, and thus the dynamic component of the sensing signal can be improved, which is beneficial to improving the accuracy of sensing.

[0018] In a possible design, the period of the first sensing resource set is A1 times of the first time period, or the first time period is B1 times of the period of the first sensing resource set, where the first time period is the accumulation time of the first sensing signal, and A1 and B1 are positive integers.

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 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.

[0022] 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, the second parameter being used to indicate a starting frequency domain unit of the set of sensing resources, D a The number of frequency domain units included in the first set of sensing resources.

[0024] Through the M sets of sensing resource sets, different devices can start to send sensing signals from starting time domain units of different sets of sensing resources. If there is only one set of sensing resource sets, the device needs to wait for P1 time to send each time the sensing demand is triggered. Through the M sets of sensing resource sets, the waiting time can be reduced (for example, to P1 / M) in the present application. Moreover, the sensing resources in different sets of sensing resources are frequency domain orthogonal in the present application, so that the devices transmitting on different sets of sensing resources do not affect the sensing performance of each other.

Through the above design, different devices can start sending sensing signals from the starting time domain unit of different sensing resource sets. If there is only one group of sensing resource sets, the device needs to wait for P1 time to send each time the sensing demand is triggered. However, by using the M groups of sensing resource sets, the waiting time can be reduced (for example, to P1 / M). In addition, the sensing resources in different sensing resource sets are orthogonal in the frequency domain, so that the devices transmitting on different sensing resource sets do not affect each other's sensing performance.

[0076] The above design can reduce signaling overhead.

[0077] In one possible design, the first information can further indicate a first time domain offset and / or a second offset value, where the first time domain offset is used to indicate that the starting time domain unit of the first set of sensing resources is a first time domain unit, or is used to indicate that the starting time domain unit of the first set of sensing resources is after the first time domain unit, or is used to indicate that the starting time domain unit of the first set of sensing resources is a starting time domain unit of a first set of sensing resources after the first time domain unit, where the first time domain unit is a time domain unit after a time domain unit where the first information is located with a first time domain offset, and the second time domain offset is used to indicate that the ending time domain unit of the first set of sensing resources is a second time domain unit, or is used to indicate that the ending time domain unit of the first set of sensing resources is after the second time domain unit, or is used to indicate that the ending time domain unit of the first set of sensing resources is an ending time domain unit of a first set of sensing resources after the second time domain unit, where the second time domain unit is a time domain unit after the time domain unit where the first information is located with a second time domain offset.

[0078] The above design can dynamically indicate the starting time domain unit of the first set of sensing resources and / or the ending time domain unit of the first set of sensing resources, and reduce signaling overhead.

[0079] In a possible design, the first information indicates the frequency domain resources of the first set of sensing resources in any of the following manners: the first information indicates at least two of the following: a starting frequency domain unit of the first set of sensing resources, an ending frequency domain unit of the first set of sensing resources, or a quantity of frequency domain units included in the first set of sensing resources; or the first information indicates a starting frequency domain unit of the first set of sensing resources, a quantity of frequency domain units included in the first set of sensing resources, or a quantity of frequency domain units of a contiguous frequency domain unit interval in the first set of sensing resources; or the first information indicates at least two of the following: a starting frequency domain unit of the first set of sensing resources, an ending frequency domain unit of the first set of sensing resources, or a frequency domain width of the first set of sensing resources; or the first information indicates a quantity of frequency domain units of the first set of sensing resources; or the first information indicates a quantity of frequency domain units of the first set of sensing resources and a quantity of frequency domain units of a contiguous frequency domain unit interval in the first set of sensing resources.

[0080] The starting frequency domain unit of the first set of sensing resources and / or the ending frequency domain unit of the first set of sensing resources can be dynamically indicated, and signaling overhead is reduced.

[0081] In a possible design, the first information is used to configure the first set of sensing resources for at least one device, and the at least one device includes the first device. The motion speed of the at least one device is less than or equal to a threshold value.

[0082] The above design can indicate a set of sensing resources common to multiple devices, and thus supports the multiple devices to transmit sensing signals on the same set of sensing resources, reducing resource overhead and signaling overhead.

[0083] In a third aspect, a sensing method is provided. An execution subject of the method is a fourth device, which can be a first device or a chip or circuit at a side of the first device. 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 set of sensing resources, the first set of sensing resources including a periodically-repeated first sensing resource; and receiving a first sensing signal on the first set of sensing resources, the first sensing signal being used to determine information of a sensing target.

[0084] In the present application, a unified configuration manner of a set of sensing resources is provided, so that different sensing transmitters (for example, the first device and the second device) can transmit sensing signals on the same set of sensing resources, thereby reducing resource overhead of sensing from a system level.

[0085] In addition, since sensing can be continuously performed, in the present application, based on a periodically-repeated set of sensing resources, the sensing transmitter and the sensing receiver can accumulate sensing signals, thereby improving accuracy of determining information of a sensing target.

[0086] In a possible design, the transmitting power of the sensing signal transmitted by each device on the first set of sensing resources remains unchanged in the second time period; or, the transmitting power of the sensing signal transmitted by each device on the first set of sensing resources changes in the same way in the second time period.

[0087] By keeping the transmitting power of the sensing signal unchanged or changing in the same way, the impact caused by the change of the transmitting power of the sensing signal can be avoided, and the impact factor of the change of the sensing signal in the first time period Tw can be ensured to be only the movement of the sensing target as much as possible. Therefore, the sensing accuracy can be improved, and the impact of devices on each other's sensing can be avoided.

[0088] In a possible design, the method further includes: receiving third information, where the third information is used to indicate the change of the transmitting power of the sensing signal transmitted on the first set of sensing resources. Through the above design, the fourth device can determine the change of the transmitting power of the sensing signal.

[0089] In a possible design, the second time period is a time domain resource of the first set of sensing resources. Through the above design, the transmitting power of the sensing signal in the first set of sensing resources can be controlled, and correspondingly, the impact factor of the change of the sensing signal can be ensured to be only the movement of the sensing target.

[0090] In a possible design, each first sensing resource included in the first set of sensing resources carries the sensing signal; and / or, each first sensing resource included in the first time period carries the sensing signal, where the first time period is the accumulation duration of the first sensing signal; and / or, each first sensing resource included in at least one period of the periodically-repeated first set of sensing resources carries the sensing signal.

[0091] By transmitting the sensing signal on each sensing resource in the set of sensing resources, the impact factor of the change of the sensing signal in the first time period Tw can be ensured to be only the movement of the sensing target as much as possible. Therefore, the sensing accuracy can be improved, and the impact of devices on each other's sensing can be avoided.

[0092] In a possible design, the first set of sensing resources is periodically repeated. Through the above design, the accumulation time of the sensing signal can be increased, and therefore the sensing accuracy can be improved.

[0093] In a possible design, the first information is used to configure the first set of sensing resources for the first device and the second device. Through the above design, multiple devices can transmit the sensing signal on the same sensing resource, and therefore the dynamic component of the sensing signal can be improved, and the sensing accuracy can be improved.

[0094] In a possible design, a period of the first sensing resource set is A1 times of the first time period, or the first time period is B1 times of the period of the first sensing resource set, where the first time period is a duration of accumulation of the first sensing signal, A1 and B1 are positive integers.

[0095] In a possible design, a period of the first sensing resource set is C a times of a period of the first sensing resource, where C a is a positive integer.

[0096] In a possible design, the first sensing resource set includes D a frequency domain units in the frequency domain, and the first sensing resource includes E a frequency domain units in the frequency domain, where the E a frequency domain units are equally spaced in the D a frequency domain units, or the E a frequency domain units are the D a frequency domain units; D a is an integer greater than 0, and E a is an integer greater than 0 and not greater than D a .

[0097] In a possible design, time domain resources of the first sensing resource set start from a time domain unit t a ; t a satisfies t a mod(P1 a )=G a , where G a is a value of a first parameter corresponding to the first sensing resource set, the first parameter is used to indicate a starting time domain unit of a sensing resource set, or the first parameter is used to indicate a starting time domain unit of each period of a sensing resource set, P1 a is a period of the first sensing resource set, or P1 a is a quantity of time domain units included in the period of the first sensing resource set. Through the above, one parameter G a can be configured to indicate the starting time domain unit of each period of the first sensing resource set, reducing signaling overhead. The first sensing resource set and the second sensing resource set correspond to different values of the first parameter, G a and G b , that is, the periodic first sensing resource set and the periodic second sensing resource set can be respectively indicated in a unified manner, that is, the starting time domain unit of each period of the first sensing resource set and the starting time domain unit of each period of the second sensing resource set are respectively indicated, reducing signaling overhead.

[0098] In a possible design, frequency domain resources of the first sensing resource set start from a frequency domain unit f a ; fa satisfies: f a mod(D a )=H a , where H a is a value of a second parameter corresponding to the first set of sensing resources, the second parameter being used to indicate a starting frequency domain unit of the set of sensing resources, D a indicating a number of frequency domain units included in the first set of sensing resources. Through the above, H a may indicate the starting frequency domain unit of the first set of sensing resources, reducing signaling overhead.

[0099] In a possible design, the first information configures M sets of sensing resources, the M sets of sensing resources including the first set of sensing resources, or the M sets of sensing resources including the first set of sensing resources and a second set of sensing resources, the second set of sensing resources including periodically repeated second sensing resources, and M being an integer greater than 1.

[0100] Through the M sets of sensing resources, different apparatuses can start to send sensing signals from starting time domain units of different sets of sensing resources. If there is only one set of sensing resources, the apparatus needs to wait for P1 time to send each time the sensing demand is triggered. Through the M sets of sensing resources, the waiting time can be reduced (for example, to P1 / M) in this application. In addition, the sensing resources in different sets of sensing resources are orthogonal in frequency domain, so that the devices transmitting on different sets of sensing resources can avoid affecting the sensing performance of each other.

[0101] In a possible design, 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 different; and / or, 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 are different. Through the above design, different apparatuses can start to send sensing signals from starting time domain units of different sets of sensing resources. If there is only one set of sensing resources, the apparatus needs to wait for P1 time to send each time the sensing demand is triggered. Through the M sets of sensing resources, the waiting time can be reduced (for example, to P1 / M) in this application. In addition, the sensing resources in different sets of sensing resources are orthogonal in frequency domain, so that the devices transmitting on different sets of sensing resources can avoid affecting the sensing performance of each other.

[0102] In a possible design, a value of a first parameter corresponding to the first set of sensing resources is G a , and a value of the first parameter corresponding to the second set of sensing resources is G bIn different embodiments, the first parameter is used to indicate a starting time domain unit of the sensing resource set, or the first parameter is used to indicate a starting time domain unit of each cycle of the sensing resource set. Through the above design, different apparatuses can start to send sensing signals from the starting time domain unit of different sensing resource sets. If there is only one group of sensing resource sets, the apparatus needs to wait for a time of P1 to send each time the sensing demand is triggered. However, through the M groups of sensing resource sets, the waiting time can be reduced (for example, to P1 / M). In addition, the sensing resources in different sensing resource sets are orthogonal in the frequency domain, so that the devices transmitting on different sensing resource sets do not affect each other's sensing performance.

[0103] In a possible design, the first sensing resource set is the sensing resource set with the earliest starting time domain unit among the M groups of sensing resource sets; or the first sensing resource set is the sensing resource set in which the sensing resource with the earliest starting time domain unit among the sensing resources included in the M groups of sensing resource sets is located. Through the above design, the waiting time for performing sensing services can be reduced.

[0104] In a possible design, the first sensing resource set is the sensing resource set with the earliest starting time domain unit among the M groups of sensing resource sets after a third time domain unit; or the first sensing resource set is the sensing resource set in which the sensing resource with the earliest starting time domain unit among the sensing resources included in the M groups of sensing resource sets is located after the third time domain unit; wherein the third time domain unit is the time domain unit in which sensing is triggered, or the third time domain unit is the time domain unit that is spaced from the time domain unit in which sensing is triggered by a third time domain offset; or the third time domain unit is related to the time domain unit in which sensing is triggered, or the third time domain unit is related to the time domain unit in which sensing is triggered and the third time domain offset; or the third time domain unit is the time domain unit in which the first information is received, or the third time domain unit is the time domain unit that is spaced from the time domain unit in which the first information is received by a third time domain offset; or the third time domain unit is related to the time domain unit in which the first information is received, or the third time domain unit is related to the time domain unit in which the first information is received and the third time domain offset. Through the above design, the waiting time for performing sensing services can be reduced.

In addition, the terms "include" and "have" and any variations thereof are intended to cover non-exclusive inclusion, so that the processes, methods, systems, products or equipment containing a series of units do not have to be limited to those units, but can include other units not clearly listed or inherent to these processes, methods, products or equipment. The methods and devices provided by the embodiments of the present application are based on the same or similar technical concepts, and since the principles of the devices and methods for solving problems are similar, the implementation of the devices and methods can be mutually referred to, and the repeated parts will not be described.

[0154] Before introducing the technical solutions provided by the embodiments of the present application, first introduce the technical terms, applicable network architecture and scenarios involved in the embodiments of the present application.

[0155] (1) Sensing, which can also be replaced by: sensing process, sensing operation, sensing detection, detection process.

[0156] Sensing can be understood as a technology capable of obtaining environmental and / or object feature information in the environment. The object feature information in the environment includes but is not limited to shape, size, direction, speed, position, distance between objects or relative motion, etc. The working principle of sensing is: the sending end sends a sensing signal, the receiving end receives the sensing signal reflected and / or scattered by the sensing target (also known as echo signal), and obtains the sensing result such as speed, distance, shape, size, etc. according to the received sensing signal. The sensing target can also be called target, detected target, sensed object, detected object or sensed target, etc. without limitation. The sensing target can be various tangible objects in the environment that can reflect electromagnetic waves. For example, the sensing target can be a stationary object such as a building. For another example, the sensing target can also be a movable object such as a vehicle, a drone or a terminal device.

[0157] Sensing target: can also be called sensed target, target, etc. The characteristics of the target are derived based on the sensing signal.

[0158] (2) Sensing signal

[0159] The sensing signal can also be referred to as a signal for sensing, a sensing reference signal, or a reference signal for sensing, etc. The sensing signal can be a signal transmitted alone, a signal transmitted together with a communication signal, or a communication signal for sensing service.

[0160] For example, the sensing signal in the embodiments can be any one of a channel state information-reference signal (CSI-RS), a synchronization signal block (SSB), a positioning reference signal (PRS), and a sounding reference signal (SRS). The SRS can be a multi-input multi-output (MIMO) SRS or a positioning SRS, etc.

[0161] The sensing signal can propagate via a path of “sensing transmitter-sensing target-sensing receiver”, via a path of “sensing transmitter-sensing receiver”, or via a path of “sensing transmitter-interference / environment-sensing receiver”. That is, the sensing signal can be any one of the above paths, or a combination of the above paths, and the sum signal of the above paths is received at the sensing receiver.

[0162] Therefore, in the embodiments, the transmitted sensing signal can be referred to as sensing signal A, and the received sensing signal can be referred to as sensing signal B. In fact, the sensing signal A and the sensing signal B are the same signal (for example, both are referred to as sensing signal). In sensing, the change of the sensing signal B compared with the sensing signal A includes the change caused by reflection or scattering via the sensing target, for example, includes the change of the time domain and / or frequency domain of the sensing signal, and for example, includes the change of the amplitude and / or phase of the sensing signal, which to some extent reflects the information of the sensing target.

[0163] (3) Resource unit

[0164] The resource includes two dimensions of time domain and / or frequency domain. The unit of the time domain resource is a time domain unit, and the unit of the frequency domain resource is a frequency domain unit.

[0165] The time domain unit can be a symbol, a slot, a mini-slot, a sub-frame, a frame, etc.

[0166] The frequency domain unit can be a resource element (RE), a resource block (RB), a channel, a subchannel, a control channel element (CCE), a resource pool, a bandwidth part (BWP), a carrier, a band, etc.

[0167] The time domain unit and the frequency domain unit above can be combined in any manner. For example, the resource unit can be a time-frequency resource unit with a symbol as the time domain unit and a resource element as the frequency domain unit. For another example, the resource unit can be a time-frequency resource unit with a symbol as the time domain unit and a resource block as the frequency domain unit.

[0168] In embodiments of the present application, the time domain unit in which the sensing signal is transmitted can also be referred to as the transmission occasion of the sensing signal, and the two can be replaced synonymously.

[0169] (4) Sensing signal accumulation

[0170] Since the sensing target needs to be sensed over time, the sensing signal needs to be transmitted periodically. For example, the sensing transmitter periodically transmits X sensing signals within a time period. By comparing the changes (such as amplitude change frequency and / or phase change frequency, etc.) of the sensing signals within the time period, it is determined whether the target is moving, or the speed of the target movement is determined. The longer the time of sensing signal accumulation, the better the speed resolution of sensing.

[0171] That is, the information of the sensing target needs to be determined based on at least one (for example, X) sensing signal accumulated within a period of time. For ease of description, the time period in which the first sensing signal is accumulated is referred to as the first time period Tw, with the first sensing signal determining the information of the sensing target as an example.

[0172] (5) Network device, refers to (radio) access network ((R)AN) device / RAN node. In embodiments of the present application, (R)AN and RAN are replaceable. The network device can also be referred to as an access network device, an access network device apparatus, a network apparatus, or a wireless network device.

[0173] The RAN can be a 3rd generation partnership project (3GPP) related cellular system, e.g., a 5G / new radio (NR) mobile communication system, or a future-oriented evolved system / network. The RAN can also be an open RAN (O-RAN or ORAN), a cloud radio access network (CRAN), or 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, a reconfigurable intelligent surface (RIS) communication network, etc. The RAN can also be a communication system in which two or more of the above systems are fused. The RAN device can also be referred to as a RAN node, a RAN entity, or an access node, etc. In future scenarios, the network device can also have other evolved forms, such as possibly not being divided into a RAN device and a core network device, and being collectively referred to as a network device.

[0174] In a possible scenario, the 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, an access network device in a mobile switching center non-terrestrial network (NTN) communication system, i.e., can be deployed in a high-altitude platform or a satellite, etc. The RAN node can be a macro base station, a micro base station, an indoor station, a relay node, a donor node / host node, or a wireless controller in a CRAN scenario, etc. The RAN node can also be a server, a wearable device, a vehicle or a vehicle-mounted device, etc. For example, the RAN node in vehicle to everything (V2X) technology can be a road side unit (RSU).

[0175] In another possible scenario, a RAN node can be a module or unit that completes part of functions of a base station; or multiple RAN nodes cooperate to assist a terminal device to implement wireless access, and different RAN nodes respectively implement part of functions of a base station. For example, a RAN node can be a centralized unit (CU), a distributed unit (DU), or a radio unit (RU), etc. The functions of the CU can be implemented by one entity, or also can be implemented by different entities. For example, the functions of the CU can be further divided, that is, the control plane and the user plane are separated and implemented by different entities, respectively, as a control plane CU entity (that is, a CU-control plane (CP) entity) and a user plane CU entity (that is, a CU-user plane (UP) entity). The CU-CP entity and the CU-UP entity can be coupled with the DU to jointly complete the functions of the RAN node. The CU and the DU can be separately arranged, or also can be included in the same network element, for example, in a baseband unit (BBU). The RU can be included in a radio frequency device or a radio frequency unit, for example, included in a remote radio unit (RRU), an active antenna processing unit (AAU), or a remote radio head (RRH). It can be understood that the RAN node can be a CU node, or a DU node, or a device including a CU node and a DU node. In addition, the CU can be divided into a RAN node in the RAN, or the CU can be divided into a core network device in the core network, which is not limited here. Any one of the CU (or CU-CP, CU-UP), DU, and RU in this application can be implemented by a software module, a hardware module, or a combination of a software module and a hardware module.

[0176] The CU and the DU can be configured according to protocol layer functions of the wireless network they implement: for example, the CU is configured to implement functions of a packet data convergence protocol (PDCP) layer and above protocol layers (e.g., a radio resource control (RRC) layer and / or a service data adaptation protocol (SDAP) layer, etc.); the DU is configured to implement functions of a protocol layer below the PDCP layer (e.g., a radio link control (RLC) layer, a MAC layer, and / or a physical (PHY) layer, etc.). For specific descriptions of the above-mentioned protocol layers, reference can be made to relevant technical specifications of 3GPP or technical specifications of other applicable communication protocols.

[0177] The above-mentioned division of processing functions of the CU and the DU according to protocol layers is only an example, and the division can also be made in other manners, which is not limited in the present application. For example, in one design, the CU or the DU can also be divided into partial processing functions of protocol layers. In one design, partial functions of the RLC layer and functions of protocol layers above the RLC layer are arranged in the CU, and the remaining functions of the RLC layer and functions of protocol layers below the RLC layer are arranged in the DU. In some examples, the CU can have no PDCP layer, i.e., only include the RRC layer. The CU-CP has no PDCP-C. The CU-UP can have no PDCP-U, or have no CU-UP at all. In some examples, the DU can have no RLC layer, only have the MAC and higher PHY layers. In addition, in some examples, there can be no CU, only the DU.

[0178] When the RAN is an O-RAN, it can also have an artificial intelligence (AI) function, for example, the O-RAN includes an intelligent controller. The intelligent controller can be a non-real-time RAN intelligent controller (non-real time RAN intelligent controller, non-RT RIC / NRT RIC), or a near-real-time RAN intelligent controller (near-real time RAN intelligent controller, near-RT RIC / nRT RIC). The non-real-time RIC can be used to implement non-real-time intelligent management of the RAN function, can implement a workflow including model training and model updating, and guide applications / functions in the nRT RIC based on a policy. The 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 modules and resources of the O-RAN are implemented.

[0179] In the embodiments of the present application, the device for implementing the function of the network device can be the network device itself, or a device capable of supporting the network device to implement the function, such as a chip system or a combination device or component that can implement the function of the network device, which can be installed in the network device. The embodiments of the present application do not limit the specific technology and specific device form adopted by the network device.

[0180] (6) Terminal device. The terminal device involved in the embodiments of the present application can be a wireless terminal device capable of receiving network device scheduling and indication information. The terminal device can also be referred to as a terminal device, a user equipment (UE), a terminal, a mobile station (MS), a mobile terminal (MT), etc. The terminal device can be a device including a wireless communication function (providing voice / data connectivity to a user). For example, a handheld device with a wireless connection function, or a vehicle-mounted device, a vehicle-mounted module, etc. At present, some examples of terminal devices are: a mobile phone, a tablet computer, a notebook computer, a palm computer, a mobile internet device (MID), a wearable device, a virtual reality (VR) device, an augmented reality (AR) device, a wireless terminal in industrial control, a wireless terminal in vehicle networking, a wireless terminal in self driving, a wireless terminal in remote medical surgery, a wireless terminal in smart grid, a wireless terminal in transportation safety, a wireless terminal in smart city, or a wireless terminal in smart home, a device-to-device (D2D) terminal device, a vehicle-to-everything (V2X) communication terminal device, a smart vehicle, a telematics box (T-box), a machine-to-machine / machine-type communications (M2M / MTC) terminal device, an internet of things (IoT) terminal device, etc. For example, the terminal device can be a vehicle-mounted device, a whole vehicle device, a vehicle-mounted module, a vehicle, an on board unit (OBU), a roadside unit (RSU), a T-box, a chip or a system on chip (SOC), etc. The above-mentioned chip or SOC can be installed in a vehicle, OBU, RSU or T-box. The wireless terminal in industrial control can be a camera, a robot, etc. The wireless terminal in smart home can be a television, an air conditioner, a sweeper, a sound box, a set-top box, etc.The terminal device can also be a V2X device, for example, a smart car or an intelligent car, a digital car, an unmanned car or a driverless car or a pilotless car or an automobile, a self-driving car or an autonomous car, a pure EV or a Battery EV, a hybrid electric vehicle (HEV), a range extended EV (REEV), a plug-in HEV (PHEV), a new energy vehicle, a road site unit (RSU). The terminal device can also be a device in device-to-device (D2D) communication, for example, an electricity meter, a water meter, and the like.

[0181] In an embodiment of the present application, the device for implementing the function of the terminal device can be the terminal device itself, or a device capable of supporting the terminal device to implement the function, such as a chip system or a combination device or component that can implement the function of the terminal device, which can be installed in the terminal device. The embodiments of the present application do not limit the specific technology and specific device form adopted by the terminal device.

[0182] The foregoing introduces some concepts related to the embodiments of the present application, and the following introduces the technical background related to the embodiments of the present application.

[0183] In the research of future communication systems, communication and perception integration (also known as perception) is an important technical direction. The communication system has perception capability, and realizes the integrated design of communication and perception. Similar to the long term evolution (LTE) / NR communication system, perception does not need to deploy a separate perception network, nor does it need to customize terminal devices, and the deployment, use, and maintenance costs are low. The perception function relies on network capability and terminal capability, and is constantly iteratively upgraded and evolved.

[0184] The forms of communication-aware integration are various, such as completing the sensing function through communication signals or assisting communication based on sensing results. The functions of sensing include target detection, etc. The sensing targets (also referred to as sensed targets) include unmanned aerial vehicle targets (UAVs), human targets (Humans), automotive vehicle targets (Automotive vehicles), automated guided vehicle targets (Automated guided vehicles), objects creating hazards on roads / railways, etc.

[0185] Currently, there is no related technology for sensing resource allocation. One possible solution is that in the time domain, a number of symbols in a time slot can be allocated for sensing. In the frequency domain, a number of REs in an RB can be allocated for sensing. However, there are three problems with this resource allocation method:

[0186] 1) Sensing capacity problem: The sensing transmitter transmits sensing signals, and the sensing receiver receives the sensing signals via scattering and reflection of the sensing targets. The change of the received sensing signals relative to the transmitted sensing signals reflects the information of the sensing targets, such as the speed and distance information of the sensing targets. Therefore, according to the conventional understanding, different sensing devices (i.e., sensing transmitters and / or sensing receivers) need to make sensing based on different sensing resources, so as to avoid interference between the sensing results of the sensing devices. It can be understood that if the same sensing resources are used, it is impossible to distinguish which sensing target causes the change of the sensing signals.

[0187] There are many devices for sensing, and if the sensing resources of different devices are completely orthogonal (i.e., different sensing resources are used), a large amount of total resources will be occupied. The utilization efficiency of the sensing resources is low. Moreover, since the resources of the system are limited, the more resources allocated to the sensing service, the less resources allocated to the communication service, which will further affect the reliability of the communication service. Therefore, under the condition that the total amount of sensing resources is limited, the number of devices that can be supported for sensing will be reduced.

[0188] 2) Sensing interference problem: According to the previous term introduction (4), it is necessary to determine the information (for example, speed) of the sensing target according to the change of the sensing signal in the first time period Tw. Assuming that the first device senses the sensing target (assuming it is sensing target 1) on the first sensing resource, and the second device senses the sensing target (which can be sensing target 1 or other sensing targets) on the first sensing resource. If the second device starts sending sensing signals halfway through the first time period Tw of the first device, as shown in FIG. 1, or if the second device stops sending sensing signals halfway through the first time period Tw of the first device, as shown in FIG. 2, it will 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 second device starting / stopping halfway, i.e., it cannot determine the information of the sensing target according to the change in the sensing signal.

[0189] 3) Sensing signal energy problem: According to the previous term introduction (2), the sensing signal can propagate via the path "sensing sender-sensing target-sensing receiver", or via the path "sensing sender-(interference / environmental-) sensing receiver". In this embodiment, the component of the path "sensing sender-sensing target-sensing receiver" is referred to as the dynamic component of the sensing signal; the component of the path "sensing sender-(interference / environmental-) sensing receiver" is referred to as the static component of the sensing signal.

[0190] The movement of the sensing target causes the change of the dynamic component of the sensing signal, which further causes the change of the sensing signal received by the sensing receiver. Since the sensing signal received by the sensing receiver is the sum signal of the dynamic component and the static component, the change of the received sensing signal represents the information of the sensing target.

[0191] Due to the long propagation path and large reflection / scattering loss, the signal energy of the dynamic component of the sensing signal arriving at the sensing receiver is small. From the perspective of relative energy, the dynamic component of the sensing signal is smaller than the sensing signal energy. If the ratio is less than a certain degree, the sensing receiver cannot distinguish the change caused by the dynamic component. From the perspective of absolute energy, the sensing signal energy of the dynamic component of the sensing signal after reflection / scattering via the sensing target is small, and the change energy of the received sensing signal is small. If the change is less than a certain degree, the sensing receiver cannot distinguish the change, and naturally cannot determine the information of the sensing target.

[0192] For example, if the propagation distance of the path "sensing sender 1-sensing target 1-sensing receiver 1" is large, the signal energy of the dynamic component of the sensing signal arriving at the sensing receiver is small, thereby causing the change energy of the received sensing signal to be small.

[0193] Based on this, the embodiment of the present application provides a sensing method and device for providing a configuration mode of sensing resources. The method and device are based on the same technical concept. Since the principles of the method and device for solving problems are similar, the implementation of the device and the method can be mutually referred to, and the repeated parts will not be described again.

[0194] The technical solution provided by the embodiment of the present application can be applied to a communication-sensing integrated system. The communication-sensing integrated system is a system in which a communication system and a sensing system are integrated. Sensing can also be understood as detection, for example, detecting the position, distance, angle, etc. of a target object. In the communication-sensing integrated system, one or more communication devices can be used as sensing nodes to form a sensing network. The working principle of sensing is to determine the attribute information (such as speed, distance, shape, size, etc.) of the sensed target by sending a signal and receiving a sensing signal (also known as a return signal) reflected by the sensed target. The sensed target can be a fixed object, such as a mountain, forest or building, or a movable object, such as a vehicle, unmanned aerial vehicle, pedestrian or terminal device. The communication device as a sensing node is also called a sensing device, sensing apparatus or detector, etc. As long as the device has a sensing function, it can be used as a sensing device, for example, a terminal device with a sensing function is one kind of sensing device.

[0195] The embodiment of the present application does not limit the type of the communication system in the communication-sensing integrated 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 an LTE, a 5th generation (5G) mobile communication system (such as a new radio (NR) communication system), or can also be applied to other future mobile communication systems, or other similar communication systems. Other similar communication systems can include wireless fidelity (WIFI), vehicle to everything (V2X), internet of things (IoT) system, narrow band internet of things (NB-IoT) system, etc.

[0196] Please refer to FIG. 3, which is a schematic diagram of various sensing modes provided by the embodiments of the present application. In FIG. 3, the sensing target is taken as a vehicle, and six sensing modes are provided. The six sensing modes are: a self-sending and self-receiving sensing mode of network device A, as shown in (1) of FIG. 3, that is, network device A sends a sensing signal and receives a sensing signal; a self-sending and self-receiving sensing mode of terminal device A, as shown in (2) of FIG. 3, that is, terminal device A sends a sensing signal and receives a sensing signal; a sensing mode in which network device A sends a sensing signal and network device B receives a sensing signal, as shown in (3) of FIG. 3; a sensing mode in which terminal device A sends a sensing signal and terminal device B receives a sensing signal, as shown in (4) of FIG. 3; a sensing mode in which network device A sends a sensing signal and terminal device A receives a sensing signal, as shown in (5) of FIG. 3; and a sensing mode in which terminal device A sends a sensing signal and network device A receives a sensing signal, as shown in (6) of FIG. 3. In FIG. 3, the terminal device is taken as a smart phone as an example.

[0197] The network architecture and service scenarios described in the embodiments of the present application are used to more clearly illustrate the technical solutions of the embodiments of the present application, and do not constitute a limitation on the technical solutions provided by the embodiments of the present application. Those skilled in the art can know that, as the network architecture evolves and new service scenarios appear, the technical solutions provided by the embodiments of the present application are also applicable to similar technical problems.

[0198] In the embodiments of the present application, "when", "if" and "whether" all refer to the case that the device will make corresponding processing under certain objective circumstances, and are not limited to time, and do not require the device to have a judgment action when implemented, nor does it mean that there are other limitations. Unless otherwise specified, "if" and "whether" can be replaced, and "when" and "in the case of" can be replaced. "When" and "if" / "whether" can be replaced.

[0199] In the present application, the sensing service can also be replaced by a sensing task / sensing session, etc.

[0200] It should be noted that the naming of each message / information in the present application is only a kind of illustration, and does not limit the name of each message / information.

[0201] It can be understood that the specific structure of the execution subject of the method provided by the embodiments of the present application is not particularly limited, and can be applied to a module in a terminal device or a network device, as long as the module can communicate according to the method provided by the embodiments of the present application by running a program in which the code of the method provided by the embodiments of the present application is recorded. In the following, the first device and the second device that transmit the sensing signal are taken as examples, and the first device and the second device can be understood as a sensing transmitter. The fourth device that receives the sensing signal is taken as an example, and the fourth device can be understood as a sensing receiver. The third device that configures the sensing resource is taken as an example. The first device can be a terminal device or a network device, or a chip, a chip system, a module, etc. in the terminal device or the network device. The second device can be a terminal device or a network device, or a chip, a chip system, a module, etc. in the terminal device or the network device. The fourth device can be a terminal device or a network device, or a chip, a chip system, a module, etc. in the terminal device or the network device. The third device can be a terminal device or a network device, or a chip, a chip system, a module, etc. in the terminal device or the network device.

[0202] The sensing transmitter that transmits the sensing signal and the sensing receiver that receives the sensing signal are located in the same network device or terminal device, and this sensing mode can be referred to as mono-static sensing. For example, the first device and the fourth device can be the same network device, for example, the sensing mode shown in (1) of FIG. 3. Alternatively, the first device and the fourth device can be the same terminal device, for example, the sensing mode shown in (2) of FIG. 3.

[0203] The sensing transmitter that transmits the sensing signal and the sensing receiver that receives the sensing signal are not located in the same network device or terminal device, and this sensing mode can be referred to as bi-static sensing. For example, the first device and the fourth device can be different network devices, for example, the sensing mode shown in (3) of FIG. 3. Alternatively, the first device and the fourth device can be different terminal devices, for example, the sensing mode shown in (4) of FIG. 3. Alternatively, the first device is a network device, and the fourth device is a terminal device, for example, the sensing mode shown in (5) of FIG. 3. Alternatively, the first device is a terminal device, and the fourth device is a network device, for example, the sensing mode shown in (6) of FIG. 3.

[0204] It can be understood that the sensing resource carries the sensing signal, and the sensing signal is transmitted on the sensing resource. In this application, the sensing resource can also be described as a sensing signal. For example, the sensing resource set including periodically repeated sensing resources can also be described as the sensing resource set including periodically repeated sensing signals. For another example, the sensing resource set can also be described as a sensing signal set, the period of the sensing resource can also be described as the period of the sensing signal, the time domain unit of the sensing resource can also be described as the time domain unit of the sensing signal, the starting time domain unit of the sensing resource can also be described as the starting time domain unit of the sensing signal, the ending time domain unit of the sensing resource can also be described as the ending time domain unit of the sensing signal, the time domain pattern of the sensing resource can also be described as the time domain pattern of the sensing signal, the frequency domain unit of the sensing resource can also be described as the frequency domain unit of the sensing signal, the starting frequency domain unit of the sensing resource can also be described as the starting frequency domain unit of the sensing signal, the ending frequency domain unit of the sensing resource can also be described as the ending frequency domain unit of the sensing signal, the frequency domain pattern of the sensing resource can also be described as the frequency domain pattern of the sensing signal, the frequency domain interval of the sensing resource can also be described as the frequency domain interval of the sensing signal, the number of frequency domain units of the sensing resource can also be described as the number of frequency domain units of the sensing signal, and the like.

[0205] For ease of description, the starting time domain unit of the sensing resource in the sensing resource set is referred to as a first starting time domain unit. That is, in a period of one sensing resource set, the starting time domain unit of the sensing resource is referred to as a first starting time domain unit. The ending time domain unit of the sensing resource in the sensing resource set is referred to as a first ending time domain unit. That is, in a period of one sensing resource set, the ending time domain unit of the sensing resource is referred to as a first ending time domain unit.

[0206] The starting time domain unit of the sensing resource set is referred to as a second starting time domain unit, and the ending time domain unit of the sensing resource set is referred to as a second ending time domain unit.

[0207] The technical solutions in the embodiments of the present application will be described below with reference to the drawings in the embodiments of the present application.

[0208] As shown in FIG. 4, it is a flowchart of a communication method provided by the embodiments of the present application.

[0209] S401, the third device determines first information.

[0210] The first information is used to configure the first sensing resource set.

[0211] It should be noted that S401 can be an optional step. For example, if the third device is a terminal device, S401 can not be performed. For another example, the first device and the third device can be a same network device, S401 can not be performed. For another example, the first device and the third device can be a same terminal device, S401 can not be performed.

[0212] In a possible implementation, the first information is used to configure the 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 the first device and the second device can both transmit the sensing signal on the first set of sensing resources. The first set of sensing resources includes the first sensing resource. That is, the first device and the second device can both transmit the sensing signal on the first sensing resource included in the first set of sensing resources.

[0213] As a possible solution, the information used to configure the first set of sensing resources for the first device and the second device can be the same information or different information.

[0214] For example, the first device and the second device receive the same first information, and the first information indicates the information of the first set of sensing resources.

[0215] For another example, the first device and the second device respectively receive different first information, and the first information respectively indicates the information of the first set of sensing resources.

[0216] As a possible solution, the information used to configure the first set of sensing resources for the first device and the fourth device in the first information can be the same information.

[0217] For example, the first device and the fourth device receive the same first information, and the first information indicates the information of the first set of sensing resources. The first set of sensing resources includes the first sensing resource. The first device transmits the first sensing signal on the first sensing resource, and the fourth device receives the first sensing signal on the first sensing resource.

[0218] For example, the second device and the fourth device receive the same first information, and the first information indicates the information of the first set of sensing resources. The first set of sensing resources includes the first sensing resource. The second device transmits the second sensing signal on the first sensing resource, and the fourth device receives the second sensing signal on the first sensing resource.

[0219] The following introduces the sensing resource set from the perspective of time domain and frequency domain, respectively. The sensing resource set involved here can be the first sensing resource set, the second sensing resource set, or other sensing resource sets. For ease of illustration, the sensing resource set m is used to refer to a certain sensing resource set in a plurality of sensing resource sets. For example, when m = 1, the sensing resource set m is the first sensing resource set; when m = 2, the sensing resource set m is the second sensing resource set; and so on.

[0220] It should be noted that the following features in the time domain and the frequency domain are optional features. The features corresponding to the time domain and the frequency domain can be implemented separately or in combination. For example, the sensing resource set can refer to a set of time domain resources, and the features thereof satisfy any one of the following time domain features; or the sensing resource set can refer to a set of frequency domain resources, and the features thereof satisfy any one of the following frequency domain features; or the sensing resource set can refer to a set of time-frequency resources, and the features thereof satisfy any one of the following time domain features, and the features thereof satisfy any one of the following frequency domain features.

[0221] 1. Time domain

[0222] The sensing resource set can be periodically repeated, as shown in FIG. 5. The period of the sensing resource set m can be P1 m , P1 m represents the repetition period of the sensing resource set m, m = 1, 2, …, M or m = 0, 1, …, M-1, where M is the number of groups of sensing resource sets, or the number of sensing resource sets, and M is a positive integer. m is the index of the sensing resource set, or the index of a group of sensing resource sets. In an exemplary description, the periodically repeated sensing resource set can be referred to as a group of sensing resource sets. P1 m is a positive integer. For example, P1 m may 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 units of seconds or radio frames. P1 m For example, it can be at least any one of 1-100, or at least any one of {100, 200, 300, 400, 500, 600, 700, 800, 900, 1000, 2000, 3000, 4000, 5000, 6000, 7000, 8000, 9000, 10000}, in units of milliseconds, symbols, time slots, or radio frames. The period of the sensing resource set can also be understood as the corresponding time length within each sensing resource set period.

[0223] Taking the first sensing resource set as an example, the period of the first sensing resource set 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.

[0224] 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.

[0225] 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.

[0226] 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 sets of sensing resources are similar and will not be repeated here.

[0227] wherein A1, A2, B1 and B2 are positive integers, for example, A1 can be at least any one of {1, 2, 3, 4, 5, 6, 7, 8, 9, 10}, 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 that A1 = 1 or B1 = 1, i.e., the period P1 a of the first set of sensing resources is equal to the first time period Tw, which can also be understood as the default value of the period P1 a of the first set of sensing resources is equal to the first time period Tw. Other sets of sensing resources are similar and will not be repeated here.

[0228] The first time period Tw is inversely proportional to the value of the speed resolution. The smaller the value of the speed resolution required by the sensing service, the longer the first time period Tw; similarly, the larger the value of the speed resolution required by the sensing service, the shorter the first time period Tw. Wherein the speed of the sensing target can be understood as the motion frequency of the sensing target, i.e., the speed resolution of the sensing target can be understood as the motion frequency resolution of the sensing target.

[0229] Alternatively, the first time period Tw is inversely proportional to the value of the speed accuracy. The smaller the value of the speed accuracy required by the sensing service, the longer the first time period Tw; similarly, the larger the value of the speed accuracy required by the sensing service, the shorter the first time period Tw. Wherein the speed accuracy of the sensing target can be understood as the motion frequency accuracy of the sensing target.

[0230] For example, 2 periods of the set of sensing resources are shown in FIG. 5. In this illustration, the period P1 m of the set of sensing resources is 10s. The first time period Tw is also 10s, and the relationship satisfies P1 m = Tw.

[0231] The set of sensing resources can have M groups. For different sets of sensing resources, the periods of the sets of sensing resources can be the same or different. An example is that different sets of sensing resources correspond to the same period, for example, P1. For example, the period of the first set of sensing resources is the same as the period of the second set of sensing resources. Another example is that different sets of sensing resources correspond to their respective periods P1 m , wherein the periods of different sets of sensing resources can be the same or different. For example, the period of the first set of sensing resources is different from the period of the second set of sensing resources.

[0232] The set of sensory resources can include periodically repeating sensory resources. For example, the first set of sensory resources can include periodically repeating first sensory resources, the 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, as shown in Figure 5. The period of the sensory resources included in the set of sensory resources 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 resource 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 relationship 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 relationship 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 .

[0233] 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.

[0234] Among them, P2 m It is a positive integer. For example, P2 mis a positive integer. For example, it can be at least any one of 1-100, or at least any one of {100, 200, 300, 400, 500, 600, 700, 800, 900, 1000, 2000, 3000, 4000, 5000, 6000, 7000, 8000, 9000, 10000}.

[0235] C m is a positive integer. C m For example, it can be at least any one of 1-100, or at least any one of {100, 200, 300, 400, 500, 600, 700, 800, 900, 1000, 2000, 3000, 4000, 5000, 6000, 7000, 8000, 9000, 10000}.

[0236] For any two of the sensing resource sets, the periods of the sensing resources included in the sensing resource set can be the same or different. In one example, the sensing resources included in different sensing resource sets correspond to the same period, for example, both are P2. In another example, the sensing resources included in different sensing resource sets correspond to respective periods P2 m , where the periods of the sensing resources included in different sensing resource sets can be the same or different.

[0237] For different sensing resource sets, the number of sensing resources included in the sensing resource set can be the same or different. In one example, the sensing resources included in different sensing resource sets correspond to the same number, for example, both are C. In another example, the sensing resources included in different sensing resource sets correspond to respective numbers C m , where the periods of the sensing resources included in different sensing resource sets can be the same or different.

[0238] In summary, different sensing resource sets (for example, the first sensing resource set and the second sensing resource set) have at least one of the following in common: the period of the sensing resource set, the number of sensing resources included in the sensing resource set, or the period of the sensing resource.

[0239] The relationship between the period of the sensing resource set and the period of the sensing resource satisfies any one of the following:

[0240] 1) P1 = C P2. It can be understood that different sensing resource sets can correspond to the same period. The sensing resources within different sensing resource sets can correspond to the same period. The number of sensing resources within different sensing resource sets can correspond to the same number.

[0241] 2) P1 m = C mP2. It can be understood that different sets of sensing resources can correspond to respective periods, and the periods of different sets of sensing resources can be the same or different. The sensing resources in different sets of sensing resources can correspond to the same period. The number of sensing resources in different sets of sensing resources can correspond to respective quantities, and the number of sensing resources included in different sets of sensing resources can be the same or different.

[0242] 3) P1 = C m P2 m It can be understood that different sets of sensing resources can correspond to the same period. The number of sensing resources included in different sets of sensing resources can correspond to respective quantities, and the number of sensing resources included in different sets of sensing resources can be the same or different. The sensing resources included in different sets of sensing resources can correspond to respective periods, and the periods of the sensing resources included in different sets of sensing resources can be the same or different.

[0243] 4) P1 m = C m P2 m It can be understood that different sets of sensing resources can correspond to respective periods, and the periods of different sets of sensing resources can be the same or different. The sensing resources included in different sets of sensing resources can correspond to the same period, and the periods of the sensing resources included in different sets of sensing resources can be the same or different. The number of sensing resources included in different sets of sensing resources can correspond to respective quantities, and the number of sensing resources included in different sets of sensing resources can be the same or different.

[0244] Therefore, the period of a set of sensing resources can be determined according to the relationship between the period of the set of sensing resources and the period of the sensing signal.

[0245] The sensing resources included in a set of sensing resources (for example, a first set of sensing resources, a second set of sensing resources, and the like) can be continuous or discrete in the time domain. For a case where the sensing resources included in a set of sensing resources are continuous in the time domain, the period P2 m of the sensing resources is equivalent to 1 time domain unit. For a case where the sensing resources included in a set of sensing resources are discrete in the time domain, the period P2 m of the sensing resources is greater than 1 time domain unit.

[0246] For example, in FIG. 5, a set of sensing resources includes 100 periodically repeated sensing resources, and the period P1 m of the set of sensing resources is 10 s. The period P2 m of the sensing resources is 200 ms, and the relationship satisfies P1 = 100 P2 m . It can be seen that the sensing resources included in the set of sensing resources in FIG. 5 are discrete in the time domain.

[0247] In at least two periods of the sensing resource set, the time domain pattern of the sensing resource within the sensing resource set is the same.

[0248] One specific example is that, in each period of the sensing resource set, the time domain pattern of the sensing resource within the sensing resource set is the same. Taking the first sensing resource set as an example, in each period of the first sensing resource set, the time domain pattern of the first sensing resource within the first sensing resource set is the same. Alternatively, it can also be described as, in each period of the first sensing resource set, the first sensing signal is transmitted according to the same time domain pattern.

[0249] In one implementation, the time domain pattern of the sensing resource in each period of the sensing resource set is the same, which can be understood as that, in each period of the sensing resource set, the intra-frame time slot index of the sensing resource in the frame where the sensing resource is located is the same. Alternatively, it can also be described as, in each period of the sensing resource set, on the frame where the sensing resource is located, the sensing signal is transmitted in at least one time slot with the same index. The at least one time slot included by the sensing resource can be continuous at least one time slot or discrete at least one time slot.

[0250] Taking the first sensing resource set as an example, in each period of the first sensing resource set, the intra-frame time slot index of the first sensing resource in the frame where the first sensing resource is located is the same. Alternatively, it can also be described as, in each period of the first sensing resource set, on 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 time domain pattern of the sensing resource in each period of the sensing resource set is the same, which can be understood as that, in each period of the sensing resource set, the intra-time slot symbol index of the sensing resource in the time slot where the sensing resource is located is the same. Alternatively, it can also be described as, in each period of the sensing resource set, on the frame where the sensing resource is located, the sensing signal is transmitted in at least one time slot with the same index. The at least one time slot included by the sensing resource can be continuous at least one time slot or discrete at least one time slot.

[0252] Taking the first sensing resource set as an example, in each period of the first sensing resource set, the intra-time slot symbol index of the first sensing resource in the time slot where the first sensing resource is located is the same. Alternatively, it can also be described as, in each period of the first sensing resource set, on 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.

[0253] In another implementation, the time domain pattern of the sensing resource in each cycle of the sensing resource set is the same, which can be understood as: in each cycle of the sensing resource set, the intra-frame time slot index of the sensing resource in the frame is the same, and in each cycle of the sensing resource set, the intra-time slot symbol index of the sensing resource in the time slot is the same. For specific examples, refer to the above two implementations, which will not be described here.

[0254] Another specific example is that the sensing signal is transmitted according to the same time domain pattern in at least two cycles of the sensing resource set. Taking the first sensing resource set as an example, in at least two cycles of the first sensing resource set, the time domain pattern of the first sensing resource in the first sensing resource set is the same. Alternatively, it can also be described as: in at least two cycles of the first sensing resource set, the first sensing signal is transmitted according to the same time domain pattern.

[0255] In an implementation, the time domain pattern of the sensing resource in at least two cycles of the sensing resource set is the same, which can be understood as: in at least two cycles of the sensing resource set, the intra-frame time slot index of the sensing resource in the frame is the same. Alternatively, it can also be described as: in at least two cycles of the sensing resource set, the sensing signal is transmitted in at least one time slot of the same index on the frame where the sensing resource is located. The at least one time slot included by the sensing resource can be continuous at least one time slot or discrete at least one time slot.

[0256] In another implementation, the time domain pattern of the sensing resource in at least two cycles of the sensing resource set is the same, which can be understood as: in at least two cycles of the sensing resource set, the intra-time slot symbol index of the sensing resource in the time slot is the same. Alternatively, it can also be described as: in at least two cycles of the sensing resource set, the sensing signal is transmitted in at least one time slot of the same index on the frame where the sensing resource is located. The at least one time slot included by the sensing resource can be continuous at least one time slot or discrete at least one time slot.

[0257] Taking the first sensing resource set as an example, in at least two cycles of the first sensing resource set, the intra-time slot symbol index of the first sensing resource in the time slot where the first sensing resource is located is the same. Alternatively, it can also be described as: in at least two cycles of the first sensing resource set, the first sensing signal is transmitted in at least one time slot of the same index on the frame where the first sensing resource is located.

[0258] In another implementation, the time domain pattern of the sensing resource in at least two periods in the sensing resource set is the same, which can be understood as: in at least two periods of the sensing resource set, the intra-frame time slot index of the sensing resource in the frame is the same, and in at least two periods of the sensing resource set, the intra-time slot symbol index of the sensing resource in the time slot is the same. For specific examples, refer to the above two implementations, which will not be described here.

[0259] In the above manner, 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.

[0260] In another implementation, the time domain pattern of the sensing resource (for example, the first sensing resource set, the second sensing resource set, etc.) in at least two periods in the sensing resource set is the same, which can also be understood as: at least two periods of the sensing resource set include the following at least two parameters of the sensing resource: the number of sensing resources, the starting time domain unit of the sensing resource, the ending time domain unit of the sensing resource, and the period of the sensing resource.

[0261] Taking the periodically repeated first sensing resource set as an example, the time domain pattern of the sensing resource in at least two periods in the first sensing resource set includes at least two cases: the number of time domain units of the first sensing resource in at least two periods of the first sensing resource set is the same; or the starting time domain unit of the first sensing resource in at least two periods of the first sensing resource set is the same; or the ending time domain unit of the first sensing resource in at least two periods of the first sensing resource set is the same; or the period of the sensing resource in at least two periods of the first sensing resource set is the same.

[0262] In another implementation, the time domain pattern of the sensing resource (for example, the first sensing resource set, the second sensing resource set, etc.) in each period in the sensing resource set is the same, which can also be understood as: each period of the sensing resource set includes the following at least two parameters of the sensing resource: the number of sensing resources, the starting time domain unit of the sensing resource, the ending time domain unit of the sensing resource, and the period of the sensing resource.

[0263] Taking the periodically repeated first sensing resource set as an example, the time domain pattern of the sensing resource in each period in the first sensing resource set includes at least two cases: the number of the first sensing resource in each period of the first sensing resource set is the same; or the starting time domain unit of the first sensing resource in each period of the first sensing resource set is the same; or the ending time domain unit of the first sensing resource in each period of the first sensing resource set is the same; or the period of the sensing resource in each period of the first sensing resource set is the same.

[0264] Optionally, the time domain pattern of the sensing resources included in different sensing resource sets can also be the same. For example, taking the first sensing resource set and the second sensing resource set as an example, the time domain pattern of the first sensing resource in the first sensing resource set and the time domain pattern of the second sensing resource in the second sensing resource set are the same.

[0265] Optionally, the first sensing resource in each period of a sensing resource set (e.g., the first sensing resource set, the second sensing resource set, etc.) is located on the first time domain unit of the sensing resource set, that is, the first time domain unit of the sensing resource set is aligned with the time domain unit where the first sensing resource in the sensing resource set is located. That is, the starting time domain unit of the sensing resources in the sensing resource set is the starting time domain unit of the sensing resource set.

[0266] Optionally, the last sensing resource in each period of a sensing resource set (e.g., the first sensing resource set, the second sensing resource set, etc.) is located on the last time domain unit of the sensing resource set, that is, the last time domain unit of the sensing resource set is aligned with the time domain unit where the last sensing resource in the sensing resource set is located. That is, the first ending time domain unit of the sensing resources in the sensing resource set is the ending time domain unit of the sensing resource set.

[0267] For example, in the first period of the sensing resource set and the second period of the sensing resource set in FIG. 5, the time domain pattern of the sensing resources is the same. In the time domain, each period of the sensing resource set includes 100 periodically repeated sensing resources.

[0268] 2, frequency domain

[0269] A sensing resource set (e.g., the first sensing resource set and / or the second sensing resource set, etc.) includes D m frequency domain units in the frequency domain. m D a 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 m a frequency domain units in the frequency domain.

[0270] wherein D m is a positive integer. D m may 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}.

[0271] For example, the frequency domain unit can be a RE or a RB.​

[0272] As an optional way, the frequency domain resources of a sensing resource set (e.g., the first sensing resource set, the second sensing resource set, 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, the frequency domain width I of the sensing resource set m , the number D of frequency domain units included in the sensing resource set m , the frequency domain interval J between every two frequency domain units in the sensing resource set m .

[0273] wherein, I m represents the frequency domain width of the sensing resource set m. I m is a positive integer, and the unit can be Hz, kHz or MHz. I 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}. It can be understood that if the first sensing resource set is the sensing resource set m, then I m = I a .

[0274] wherein, J m represents the frequency domain interval between every two frequency domain units in the sensing resource set m. J m is a positive integer. J m The unit of J m may be Hz, kHz or MHz, or RE or RB. 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}. It can be understood that if the first sensing resource set is the sensing resource set m, then J = J a .

[0275] For different sensing resource sets, the frequency domain width of the sensing resource set can be the same or different. In one example, different sensing resource sets correspond to the same frequency domain width, for example, I. In another example, different sensing resource sets correspond to respective frequency domain widths I m , wherein for any two sensing resource sets, the frequency domain width of the sensing resource set can be the same or different.

[0276] For different sensing resource sets, the frequency domain interval between every two frequency domain units in the sensing resource set can be the same or different. In one example, different sensing resource sets can correspond to the same frequency domain interval, for example, J. In another example, different sensing resource sets correspond to respective frequency domain intervals J mFor any two of the sensing resource sets, the frequency domain interval of the sensing resource set can be the same or different.

[0277] The frequency domain resources or units of a sensing resource set (e.g., the first sensing resource set, the second sensing resource set, etc.) can be continuous or discrete.

[0278] In the continuous manner, the number of frequency domain units of a sensing resource set (e.g., the first sensing resource set, the second sensing resource set, etc.) can be equal to the frequency domain width of the sensing resource set.

[0279] In the discrete manner, the sensing resource set (e.g., the first sensing resource set, the second sensing resource set, etc.) can be comb-like distributed. The frequency domain width of the sensing resource set can be determined by the number of frequency domain units of the sensing resource set and the frequency domain interval between every two frequency domain units in the sensing resource set. For example, the frequency domain width of the sensing resource set and the number of frequency domain units of the sensing resource set satisfy: m = D m · J m or m = (D m - 1) · J m + 1.

[0280] The sensing resource set includes E m frequency domain units of sensing resources in the frequency domain. That is, in the time domain unit where the sensing resource is located, the sensing resource set includes E m frequency domain units of sensing resources in the frequency domain. Wherein E m represents the number of frequency domain units of 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 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}.

[0281] Optionally, in the time domain unit where the sensing resource is located, 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 intervals, and the frequency domain interval between every two frequency domain units of the sensing resource is F m .

[0282] For example, on the time domain unit where the first sensing resource is located, the first sensing resources within the first set of sensing resources are distributed with equal frequency domain interval. The frequency domain interval between every two frequency domain units of the first sensing resource is F m =F a .

[0283] For another example, on the time domain unit where the second sensing resource is located, the second sensing resources within the second set of sensing resources are distributed with equal frequency domain interval. The frequency domain interval between every two frequency domain units of the second sensing resource is F m =F b .

[0284] wherein F m represents the frequency domain interval 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 set of sensing resources, F m =F a . F m F is a positive integer. F m may be in Hz, kHz or MHz, or RE or RB. The frequency domain interval F m may 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}. The frequency domain interval F m is the interval between every two frequency domain start positions of the sensing resources, or the interval between every two frequency domain end positions of the sensing resources. Every two frequency domain end positions of the sensing resources to the frequency domain start positions can be spaced by F′ m , F′ m may satisfy F′ m +1=F m . Every two frequency domain start positions of the sensing resources to the frequency domain end positions can be spaced by F″ m , then F″ m -1=F m .

[0285] Optionally, within a sensing resource set (e.g. the first set of sensing resources, the second set of sensing resources, etc.), the number of frequency domain units of the sensing resource set on the time domain unit where the sensing resource is located can be an integer multiple of the number of frequency domain units of the sensing resource. That is, within the sensing resource set, the number of frequency domain units of the sensing resource set on the time domain unit where the sensing resource is located and the number of frequency domain units of the sensing resource satisfy: D m =F m ·E mFor example, taking the first set of sensing resources as an example, in the first set of sensing resources, on the time domain unit where the first sensing resource is located, 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 resource satisfies: D a = F a · E a .

[0286] For example, in FIG. 5, the set of sensing resources includes 20 frequency domain units, and on the time domain unit where the sensing resource is located, every 5 frequency domain units include 1 frequency domain unit of the sensing resource.

[0287] For another example, the set of sensing resources includes 4 frequency domain units. In each set of sensing resources, on the time domain unit where the sensing resource is located, 4 frequency domain units including the sensing resource. On the time domain unit where the sensing resource is located, every 5 consecutive frequency domain units include 1 frequency domain unit of the set of sensing resources.

[0288] The sensing resources in the set of sensing resources (such as the first set of sensing resources, the second set of sensing resources, etc.) can be continuous or discrete in the frequency domain.

[0289] For the case that the sensing resources in the set of sensing resources are continuous in the frequency domain, the number of frequency domain units of the set of sensing resources (such as the first set of sensing resources, the second set of sensing resources, etc.) can be equal to the number of frequency domain units of the sensing resource. For example, taking the first set of sensing resources as an example, the first set of sensing resources includes D a frequency domain units in the frequency domain, and the first sensing resource includes E a frequency domain units in the frequency domain, where E a frequency domain units are D a frequency domain units. Optionally, in this way, the set of sensing resources and the sensing resource can be configured through a signaling.

[0290] For the case that the sensing resources in the set of sensing resources are discrete, the sensing resource can be comb distributed in the set of sensing resources, for example, the first sensing resource can be comb distributed in the first set of sensing resources.

[0291] In the case that the sensing resources in the set of sensing resources are discrete, if the frequency domain units of the set of sensing resources are continuous, the relationship between the number of frequency domain units D m of the set of sensing resources and the number of frequency domain units E m of the sensing resource satisfies: D m = F m · E m . For example, taking the first set of sensing resources as an example, the first set of sensing resources includes D a frequency domain units in the frequency domain, and the first sensing resource includes Ea E frequency domain units, wherein, E m The E frequency domain units are distributed with equal interval in the D m frequency domain units, for example, D m = F m · E m . Alternatively, in this way, the sensing resource set and the sensing resource can be configured respectively by two signaling.

[0292] In the case that the sensing resources in the sensing resource set are discrete, if the frequency domain units of the sensing resource set are discrete, the frequency domain units of the sensing resource set are the frequency domain units of the sensing resource, or the frequency domain units of the sensing resource are the frequency domain units of the sensing resource set. The number of the frequency domain units of the sensing resource set is equal to the number of the frequency domain units of the sensing resource, or the default value of the number of the frequency domain units of the sensing resource set is equal to the number of the frequency domain units of the sensing resource, i.e., D m = E m . The frequency domain interval between every two frequency domain units in the sensing resource set is equal to the frequency domain interval between every two frequency domain units of the sensing resource, or the default value of the frequency domain interval J between every two frequency domain units in the sensing resource set is equal to the frequency domain interval between every 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 resource, or the frequency domain width of the sensing resource set is equal to the frequency domain width of the sensing resource by default.

[0293] For example, taking the first sensing resource set as an example, the first sensing resource set includes D a frequency domain units in the frequency domain, the first sensing resource includes E a frequency domain units in the frequency domain, the frequency domain units of the first sensing resource set are the frequency domain units of the first sensing resource, or the frequency domain units of the first sensing resource are the frequency domain units of the first sensing resource set. The number of the frequency domain units of the first sensing resource set is equal to the number of the frequency domain units of the first sensing resource, or the default value of the number of the frequency domain units of the first sensing resource set is equal to the number of the frequency domain units of the first sensing resource, i.e., D a = E a . The frequency domain interval between every two frequency domain units in the first sensing resource set is equal to the frequency domain interval between every two frequency domain units of the first sensing resource, or the default value of the frequency domain interval between every two frequency domain units in the first sensing resource set is equal to the frequency domain interval between every two frequency domain units of the first sensing resource, i.e., J a = F a . The frequency domain width of the first sensing resource set is equal to the frequency domain width of the first sensing resource, or the frequency domain width of the first sensing resource set is equal to the frequency domain width of the first sensing resource by default. In the above case, Ea D a is the number of frequency domain units in the perception resource set.

[0294] In summary, different perception resource sets (e.g., the first perception resource set and the second perception resource set) have at least one of the following in common: the number of frequency domain units included in the perception resource set, the number of frequency domain units included in the perception resource, or the number of frequency domain units included in the interval between two adjacent frequency domain units of the perception resource. For example, the relationship between the number of frequency domain units of the perception resource set and the number of frequency domain units of the perception resource in the perception resource set satisfies any one of the following:

[0295] 1) D = F · E. It can be understood that the number of frequency domain units of different perception resource sets can correspond to the same number. The number of frequency domain units of the perception resource in different perception resource sets can correspond to the same number. The frequency domain interval between every two frequency domain units of the perception resource in different perception resource sets can correspond to the same frequency domain interval.

[0296] 2) D m = F m · E. It can be understood that the number of frequency domain units of different perception resource sets can correspond to respective numbers. The number of frequency domain units of the perception resource in different perception resource sets can correspond to the same number. The frequency domain interval between every two frequency domain units of the perception resource in different perception resource sets can correspond to respective frequency domain intervals.

[0297] 3) D = F m · E m . It can be understood that the number of frequency domain units of different perception resource sets can correspond to the same number. The number of frequency domain units of the perception resource in different perception resource sets can correspond to respective numbers. The frequency domain interval between every two frequency domain units of the perception resource in different perception resource sets can correspond to respective frequency domain intervals.

[0298] 4) D m = F m · E m . It can be understood that the number of frequency domain units of different perception resource sets can correspond to respective numbers. The number of frequency domain units of the perception resource in different perception resource sets can correspond to the same number. The frequency domain interval between every two frequency domain units of the perception resource in different perception resource sets can correspond to respective frequency domain intervals.

[0299] 5) D = E. It can be understood that the number of frequency domain units of different perception resource sets can correspond to the same number. The number of frequency domain units of the perception resource in different perception resource sets can correspond to the same number.

[0300] 6) D m = Em It can be understood that the number of frequency domain units of different sensing resource sets can correspond to respective numbers. The number of frequency domain units of sensing resources in different sensing resource sets can correspond to respective numbers.

[0301] In at least two periods of the sensing resource set, the frequency domain pattern of the sensing resource in the sensing resource set is the same.

[0302] A specific example is that, in each period of the sensing resource set, the frequency domain pattern of the sensing resource in the sensing resource set is the same.

[0303] The above manner can also be described as, in 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, in each period of the first sensing resource set, the frequency domain pattern of the first sensing resource in the first sensing resource set is the same. Or, it can also be described as, in each period of the first sensing resource set, the first sensing signal is transmitted according to the same frequency domain pattern.

[0304] In an implementation manner, the frequency domain pattern of the sensing resource in each period of the sensing resource set is the same, which can be understood as that, in each period of the sensing resource set, the RE index of the sensing resource on the RB is the same. Or, it can also be described as, in each period of the sensing resource set, on the frame where the sensing resource is located, the sensing signal is transmitted on at least one RE with the same index. The at least one RE included by the sensing resource can be continuous at least one RE, or can be discrete at least one RE.

[0305] Taking the first sensing resource set as an example, in each period of the first sensing resource set, the RE index of the first sensing resource on the RB where the first sensing resource is located is the same. Or, it can also be described as, in each period of the first sensing resource set, 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.

[0306] Another specific example is that, in at least two periods of the sensing resource set, the frequency domain pattern of the sensing resource in the sensing resource set is the same.

[0307] The above manner can also be described as, in 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, in at least two periods of the first sensing resource set, the frequency domain pattern of the first sensing resource in the first sensing resource set is the same. Or, it can also be described as, in at least two periods of the first sensing resource set, the first sensing signal is transmitted according to the same frequency domain pattern.

[0308] In an implementation, the frequency domain pattern of the sensing resource in at least two periods in the sensing resource set is the same, which can be understood as: in at least two periods of the sensing resource set, the RE index of the sensing resource in the RB is the same. Alternatively, it can also be described as: in at least two periods of the sensing resource set, the sensing signal is transmitted on at least one RE with the same index on the frame where the sensing resource is located. The at least one RE included in the sensing resource can be a continuous at least one RE or a discrete at least one RE.

[0309] Taking the first sensing resource set as an example, in at least two periods of the first sensing resource set, the RE index of the first sensing resource in the RB where the first sensing resource is located is the same. Alternatively, it can also be described as: in at least two periods of the first sensing resource set, the first sensing signal is transmitted on at least one RE with the same index on the frame where the first sensing resource is located.

[0310] In the above manner, the frequency domain resource of the sensing resource set can be an integer multiple of the RB.

[0311] In another implementation, the frequency domain pattern of the sensing resource in at least two periods in the sensing resource set is the same, which can be understood as: in the time domain unit where the sensing resource is located, the following at least two parameters of the sensing resource included in at least two periods of the sensing resource set are the same: the number of frequency domain units of the sensing resource, the starting frequency domain unit of the sensing resource, the ending frequency domain unit of the sensing resource, the interval of every two frequency domain units of the sensing resource, and the frequency domain width of the sensing resource.

[0312] Taking the periodically repeated first sensing resource set as an example, the frequency domain pattern of the sensing resource in at least two periods in the sensing resource set is the same, which includes at least two cases: the number of frequency domain units of the first sensing resource in at least two periods of the first sensing resource set is the same; or the first starting frequency domain unit of the first sensing resource in at least two periods of the first sensing resource set is the same; or the first ending frequency domain unit of the first sensing resource in at least two periods of the first sensing resource set is the same; or the interval of every two frequency domain units of the first sensing resource in at least two periods of the first sensing resource set is the same; or the frequency domain width of the first sensing resource in at least two periods of the first sensing resource set is the same.

[0313] In another implementation, the frequency domain pattern of the sensing resource in each period of the sensing resource set is the same, which can be understood as: in the time domain unit where the sensing resource is located, the following at least two parameters of the sensing resource included in each period of the sensing resource set are the same: the number of frequency domain units of the sensing resource, the starting frequency domain unit of the sensing resource, the ending frequency domain unit of the sensing resource, the interval of every two frequency domain units of the sensing resource, and the frequency domain width of the sensing resource.

[0314] Taking the periodically repeated first sensing resource set as an example, the frequency domain pattern of the sensing resource in each period of the sensing resource set is the same, which includes at least two cases: the number of frequency domain units of the first sensing resource in each period of the first sensing resource set is the same; or the first starting frequency domain unit of the first sensing resource in each period of the first sensing resource set is the same; or the first ending frequency domain unit of the first sensing resource in each period of the first sensing resource set is the same; or the interval of every two frequency domain units of the first sensing resource in each period of the first sensing resource set is the same; or the frequency domain width of the first sensing resource in each period of the first sensing resource set is the same.

[0315] Optionally, the frequency domain patterns of the sensing resources included in different sensing resource sets can also be the same. For example, taking the first sensing resource set and the second sensing resource set as an example, the frequency domain pattern of the first sensing resource in the first sensing resource set is the same as the frequency domain pattern of the second sensing resource in the second sensing resource set.

[0316] Optionally, in each period of the sensing resource set (for example, 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. That is, the lowest frequency domain unit of the sensing resource in the sensing resource set is the lowest frequency domain unit of the sensing resource set.

[0317] Optionally, in each period of the sensing resource set (for example, 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. That is, the highest frequency domain unit of the sensing resource in the sensing resource set is the highest frequency domain unit of the sensing resource set.

[0318] For example, it is shown in FIG. 5 that the frequency domain pattern of the sensing resource is the same in the first period of the sensing resource set and the second period of the sensing resource set. In each period of the sensing resource set, the number of frequency domain units of the sensing resource on the time domain unit where the sensing resource is located is 4, and the starting frequency domain unit of the sensing resource coincides with the starting frequency domain unit in the sensing resource set.

[0319] In the embodiments of the present 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", and the like.

[0320] The sensing resource set is introduced above from the perspective of time domain and frequency domain.

[0321] Optionally, the sensing resource set can have one or more. Taking M groups of sensing resource sets as an example, the M groups of sensing resource sets include {sensing resource set 1, sensing resource set 2, …, sensing resource set m, …, sensing resource set M}.

[0322] In a possible implementation, the first information can configure M groups of sensing resource sets, and the first sensing resource set can be one sensing resource set in the M groups of sensing resource sets. Optionally, the M groups of sensing resource sets can also include the second sensing resource set.

[0323] The characteristics of the first sensing resource set and the second sensing resource set in the time domain and the frequency domain can be referred to the foregoing description. Optionally, the characteristics of other sensing resource sets in the M groups of sensing resource sets in the time domain and the frequency domain can also be referred to the foregoing description.

[0324] The way of determining the time domain and / or frequency domain of the M groups of sensing resource sets, or the time domain and / or frequency domain of any sensing resource set in the M groups of sensing resource sets, is introduced below from the perspective of time domain and frequency domain respectively.

[0325] It should be noted that the corresponding mode of the time domain and the frequency domain can be implemented separately or in combination. For example, the M groups of sensing resource sets can refer to M groups of time domain resource sets, and the characteristics satisfy any one of the following time domain characteristics; or the M groups of sensing resource sets can refer to M groups of frequency domain resource sets, and the characteristics satisfy any one of the following frequency domain characteristics; or the M groups of sensing resource sets can refer to M groups of time-frequency resource sets, and the characteristics satisfy any one of the following time domain characteristics, and the characteristics satisfy any one of the following frequency domain characteristics.

[0326] 1. Time domain

[0327] The starting time domain units of at least two of the M sets of sensing resources are different. Alternatively, it can also be described that the starting time domain units of each period of at least two of the M sets of sensing resources are different. For example, the starting time domain unit of the first set of sensing resources is different from the starting time domain unit of the second set of sensing resources. Alternatively, it can also be described that the starting time domain unit of each period of the first set of sensing resources is different from the starting time domain unit of each period of the second set of sensing resources. As shown in FIG. 6.

[0328] In one specific example, the starting time domain units of the 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. The starting time domain unit of each set of sensing resources in the M sets of sensing resources is different. Alternatively, it can also be described that the starting time domain unit of each period of each set of sensing resources in the M sets of sensing resources is different. For example, the starting time domain unit of the first set of sensing resources is different from the starting time domain unit of the second set of sensing resources. Alternatively, it can also be described that the starting time domain unit of each period of the first set of sensing resources is different from the starting time domain unit of each period of the second set of sensing resources.

[0329] For example, the M sets of sensing resources satisfy at least one of the following:

[0330] The time domain units of the M sets of sensing resources are orthogonal, or the time domain units of the sensing resources included in the M sets of sensing resources are orthogonal;

[0331] The time domain units of the M sets of sensing resources are orthogonal, for example, the starting time domain unit of the first period of the first set of sensing resources is time slot 1, and the ending time domain unit of the last period is time slot 6, the starting time domain unit of the first period of the second set of sensing resources is time slot 7, and the ending time domain unit is time slot 12.

[0332] The time domain units of the sensing resources included in the M sets of sensing resources are orthogonal, as shown in FIG. 7, for example, the time domain units where the sensing resources in the first set of sensing resources are located are time slot 1, time slot 3, time slot 5, and time slot 7, and the time domain units where the sensing resources in the second set of sensing resources are located are time slot 2, time slot 4, time slot 6, and time slot 8.

[0333] One way to determine the time domain resources of a set of sensing resources is that the time domain resources of the set of sensing resources m start from time domain unit t m and end at time domain unit t m , which satisfies t m mod (P1 m ) = G m , where G mThe 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.

[0334] 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.

[0335] 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 bThe value of the first parameter corresponding to the second set of sensing resources, the first parameter being used to indicate the starting time domain unit of the set of sensing resources, or the first parameter being used to indicate the starting time domain unit of each period of the set of sensing resources, that is, G b is used to indicate the starting time domain unit of the second set of sensing resources, or the starting time domain unit of each period of the second set of sensing resources. b is the period of the second set of sensing resources, or P1 b is the number of time domain units included in the period of the second set of sensing resources.

[0336] For example, the periods of different sets of sensing resources are the same (for example, all P1), and t m satisfies: t m mod(P1)=G m ; or the number of time domain units included in the periods of different sets of sensing resources is the same (for example, all P1), and t m satisfies: t m mod(P1)=G m .

[0337] Optionally, the starting time domain units of at least two sets of sensing resources in the M sets of sensing resources are different. It can also be understood that the G m corresponding to the first set of sensing resources is different from the G a corresponding to the second set of sensing resources. b

[0338] For example, the starting time domain units of each set of sensing resources in the M sets of sensing resources are different. It can also be understood that the G m corresponding to each set of sensing resources in the M sets of sensing resources is different.

[0339] Optionally, for the sensing resource set m, the starting time domain unit of the sensing resource set is the starting time slot m of the sensing resource set, that is, the time domain unit t m represents the time slot number of the starting time slot. Or, the starting time domain unit of the sensing resource set is the starting frame m of the sensing resource set, that is, the time domain unit t m represents the frame number of the starting frame. The frame number may be a system frame number (SFN) or a direct frame number (DFN), for example.

[0340] For example, the periods of the M sets of sensing resources are all 100 ms, for the first set of sensing resources, G1=G a ​= 0, the time domain resources of the first sensing resource set include a set of corresponding slots within 100 ms starting from slot 0. The first sensing resource set also includes a set of corresponding slots within 100 ms starting from slot 100 (i.e., the 2nd period), a set of corresponding slots within 100 ms starting from slot 200 (i.e., the 3rd period), a set of corresponding slots within 100 ms starting from slot 300 (i.e., the 4th period), and so on.

[0341] For the second sensing resource set, G2= G b = 10, the time domain resources of the second sensing resource set include a set of corresponding slots within 100 ms starting from slot 10. The second sensing resource set also includes a set of corresponding slots within 100 ms starting from slot 110 (i.e., the 2nd period), a set of corresponding slots within 100 ms starting from slot 210 (i.e., the 3rd period), a set of corresponding slots within 100 ms starting from slot 310 (i.e., the 4th period), and so on.

[0342] The time domain resource determination manner of other sensing resource sets is similar and will not be repeated.

[0343] If the periods of the M groups of sensing resource sets are all 100 ms, at 15 kHz SCS, for example, the period of the first sensing resource set includes 100 slots, G1= 0, the time domain resources of the first sensing resource set include a set of corresponding slots within 100 slots starting from slot 0. The first sensing resource set of the period also includes a set of corresponding slots within 100 slots starting from slot 100 (i.e., the 2nd period), a set of corresponding slots within 100 slots starting from slot 200 (i.e., the 3rd period), a set of corresponding slots within 100 slots starting from slot 300 (i.e., the 4th period), and so on.

[0344] For the second sensing resource set, G2= 10, the time domain resources of the second sensing resource set include a set of corresponding slots within 100 slots starting from slot 10. The second sensing resource set of the period also includes a set of corresponding slots within 100 slots starting from slot 110 (i.e., the 2nd period), a set of corresponding slots within 100 slots starting from slot 210 (i.e., the 3rd period), a set of corresponding slots within 100 slots starting from slot 310 (i.e., the 4th period), and so on.

[0345] The time domain resource determination manner of other sensing resource sets is similar and will not be repeated.

[0346] Taking a first sensing resource set with a period of 100 ms and a second sensing resource set with a period of 200 ms as examples, for the first sensing resource set, G1 = 0, the time domain resource of the first sensing resource set includes a set of time slots corresponding to 100 ms starting from time slot 0. The first sensing resource set also includes a set of time slots corresponding to 100 ms starting from time slot 100 (i.e., the second period), a set of time slots corresponding to 100 ms starting from time slot 200 (i.e., the third period), a set of time slots corresponding to 100 ms starting from time slot 300 (i.e., the fourth period), and so on.

[0347] For the second sensing resource set, G2 = 10, the time domain resource of the second sensing resource set includes a set of time slots corresponding to 200 ms starting from time slot 10. The second sensing resource set also includes a set of time slots corresponding to 200 ms starting from time slot 210 (i.e., the second period), a set of time slots corresponding to 200 ms starting from time slot 410 (i.e., the third period), a set of time slots corresponding to 200 ms starting from time slot 610 (i.e., the fourth period), and so on.

[0348] The determination manner of the time domain resource of other sensing resource sets is similar and will not be described herein again.

[0349] Taking a first sensing resource set with a period of 100 ms and a second sensing resource set with a period of 200 ms as examples, for the first sensing resource set, G1 = 0, the time domain resource of the first sensing resource set includes a set of time slots corresponding to 100 ms starting from time slot 0. The first sensing resource set also includes a set of time slots corresponding to 100 ms starting from time slot 100 (i.e., the second period), a set of time slots corresponding to 100 ms starting from time slot 200 (i.e., the third period), a set of time slots corresponding to 100 ms starting from time slot 300 (i.e., the fourth period), and so on.

[0350] For the second sensing resource set, G2 = 10, the time domain resource of the second sensing resource set includes a set of time slots corresponding to 200 ms starting from time slot 10. The second sensing resource set also includes a set of time slots corresponding to 200 ms starting from time slot 210 (i.e., the second period), a set of time slots corresponding to 200 ms starting from time slot 410 (i.e., the third period), a set of time slots corresponding to 200 ms starting from time slot 610 (i.e., the fourth period), and so on.

[0351] The determination manner of the time domain resource of other sensing resource sets is similar and will not be described herein again.

[0352] 2. Frequency Domain

[0353] 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".

[0354] 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.

[0355] 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".

[0356] For example, the M sets of sensing resources can satisfy at least one of the following:

[0357] 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.

[0358] The frequency domain units of the M sets of sensing resources are orthogonal, as shown in Figure 6. For example, the starting frequency domain unit of the first set of sensing resources is RE1 and the ending frequency domain unit is RE10, and the starting frequency domain unit of the second set of sensing resources is RE11 and the ending frequency domain unit is RE20.

[0359] The frequency domain units of the sensing resources included in the M sets of sensing resources are orthogonal, as shown in Figure 8. For example, the frequency domain units of the sensing resources in the first set of sensing resources are RE1, RE3, RE5, and RE7, and the time domain units of the sensing resources in the second set of sensing resources are RE2, RE4, RE6, and RE8.

[0360] 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. mH m is used to indicate the starting frequency domain unit of the first set of sensing resources.

[0361] It can be understood that, taking the first set of sensing resources as an example, H m a , f m a , D m a That is, the frequency domain resources of the first set of sensing resources start from the frequency domain unit f a ; f a satisfies: f a mod(D a )=H a , wherein H a is a value of a second parameter corresponding to the first set of sensing resources, and the second parameter is used to indicate the starting frequency domain unit of the set of sensing resources, that is, H a is 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.

[0362] Taking the second set of sensing resources as an example, H m b , f m b , D m b That is, the frequency domain resources of the second set of sensing resources start from the frequency domain unit f b ; f b satisfies: f b mod(D a )=H b , wherein H b is a value of a second parameter corresponding to the second set of sensing resources, and the second parameter is used to indicate the starting frequency domain unit of the set of sensing resources, that is, H b is 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.

[0363] Exemplarily, the number of frequency domain units of different sets of sensing resources is the same (for example, all are D), and f m satisfies: f m mod(D)=H m .

[0364] Optionally, the frequency domain units of at least two sets of sensing resources in the M sets of sensing resources are orthogonal, which can be understood as that the H m ​​​​​​Different. For example, the value of the second parameter corresponding to the first set of sensing resources is H a and the value of the second parameter corresponding to the second set of sensing resources is H b Different, wherein the second parameter is used to indicate the starting frequency domain unit of the set of sensing resources.

[0365] For example, the frequency domain units of each set of sensing resources in the M sets of sensing resources are orthogonal. It can be understood that the H m of each set of sensing resources in the M sets of sensing resources are different.

[0366] Optionally, for the 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 represents the RB index of the starting RB. Alternatively, the starting frequency domain unit of the set of sensing resources can be understood as the starting RE of the set of sensing resources with index m, i.e., the frequency domain unit f m represents the RE index of the starting RE.

[0367] The above introduces the M sets of sensing resources. The following introduces a way of configuring the M sets of sensing resources.

[0368] In one possible way, the first information can indicate the time domain resources of the set of sensing resources. For example, the first information can indicate the period of the set of sensing resources, etc.

[0369] In one implementation, the first information can indicate the period of the set of sensing resources in a direct indication manner. For example, taking the first set of sensing resources as an example, the first information indicates the period of the first set of sensing resources or indicates the number of time domain units included in the period of the first set of sensing resources.

[0370] It can be understood that if the M sets of sensing resources correspond to the same period, the first information can uniformly indicate the period for the M sets of sensing resources.

[0371] Similarly, if the periods of the M sets of sensing resources include the same number of time domain units, the first information can uniformly indicate the number of time domain units included in the period for the M sets of sensing resources.

[0372] If the M sets of sensing resources correspond to respective periods, the third apparatus can indicate the periods for the M sets of sensing resources respectively. Specifically, one information (e.g., the first information) can be used to indicate the respective periods of the M sets of sensing resources, or M information can be used to indicate the respective periods of the M sets of sensing resources.

[0373] Similarly, if the number of time domain units included in the period of the M groups of sensing resource sets corresponds to the respective number, the third device can indicate the number of time domain units included in the period for the M groups of sensing resource sets respectively. Specifically, the number of time domain units corresponding to the M groups of sensing resource sets respectively can be indicated by one information (e.g., the first information), or the number of time domain units corresponding to the M groups of sensing resource sets respectively can be indicated by M information.

[0374] In another implementation, the first information can also be indirectly indicated by indicating the number of sensing resources included in the sensing resource set and / or the period of the sensing resource, and the like.

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

[0376] For example, taking the first sensing resource set as an example, the first information can indicate the period of the first sensing resource and the number of first sensing resources included in the first sensing resource set.

[0377] For example, taking the first sensing resource set as an example, the first information can indicate the period of the first sensing resource, and optionally, the third device can also send second information, which can indicate the number of first sensing resources included in the first sensing resource set. Thus, the first device can determine the period of the first sensing resource set according to the number of first sensing resources and the period of the first sensing resource.

[0378] It can be understood that if the sensing resources of the M groups of sensing resource sets correspond to the same period, the first information can indicate the period of the sensing resource for the M groups of sensing resource sets uniformly. If the sensing resources of the M groups of sensing resource sets correspond to the respective period, the third device can indicate the period of the sensing resource for the M groups of sensing resource sets respectively. Specifically, the period of the sensing resource corresponding to the M groups of sensing resource sets respectively can be indicated by one information, or the period of the sensing resource corresponding to the M groups of sensing resource sets respectively can be indicated by M information.

[0379] If the number of sensing resources corresponding to the M groups of sensing resource sets is the same, the first information can indicate the number of sensing resources for the M groups of sensing resource sets uniformly. If the number of sensing resources corresponding to the M groups of sensing resource sets is different, the third device can indicate the number of sensing resources for the M groups of sensing resource sets respectively. Specifically, the number of sensing resources corresponding to the M groups of sensing resource sets respectively can be indicated by one information, or the number of sensing resources corresponding to the M groups of sensing resource sets respectively can be indicated by M information.

[0380] The first information can also indicate a starting time domain unit of the sensing resource set, for example, the first information can indicate G m . Taking the first sensing resource set m as an example, the first information can indicate G a .

[0381] Optionally, the sensing configuration end can indicate the number M of the sensing resource sets through the first information.

[0382] In an implementation manner, the first information can directly indicate the number M of the sensing resource sets.

[0383] For example, the first information can directly indicate the number M of the sensing resource sets M = 1. Then the sensing resource sets include the first sensing resource set.

[0384] For example, the first information can directly indicate the number M of the sensing resource sets M = 2. Then the sensing resource sets include the first sensing resource set and the second sensing resource set.

[0385] In another implementation manner, the first information can indicate the value G or G m of the first parameter.

[0386] 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 sensing resource set indicated by the first information is the first sensing resource set.

[0387] 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 a set of time slots corresponding to P1 time from time slot t m , where time slot t m satisfies t m mod (P1) = G1. Where P1 is the period of the first sensing resource set.

[0388] For another example, the first information indicates the value G of the first parameter and the number M of the sensing resource sets. That is, the first information indicates one first parameter, and the value of the first parameter is G. Where the values of the first parameters of the M sensing resource sets are the same, and are all G. 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}.

[0389] 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 a set of time slots corresponding to P1 time from time slot t mThe 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.

[0390] 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}.

[0391] 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.

[0392] In another implementation, the first information can indicate the period of the sensing resource set.

[0393] 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.

[0394] 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.

[0395] 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}.

[0396] 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 m mod(P12) = G2. G1 and G2 can be the same or different; this example does not impose any restrictions.

[0397] 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}.

[0398] 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. mThe 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.

[0399] 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.

[0400] 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.

[0401] 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.

[0402] 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}.

[0403] 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.

[0404] 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}.

[0405] For example, the first information indicates two sensing resource periods P21 and P22. P21 and P22 indicate the number of sensing resources in the first sensing resource set and the second sensing resource set respectively. m If the number of sensing resources is two (i.e., P21 and P22), the first information indicates M = 2 sensing resource sets. P21 and P22 indicate the repetition period of the sensing resources in the first sensing resource set and the second sensing resource set respectively.

[0406] In another implementation, the first information can indicate the number of sensing resources. It can be understood that the first information indicates the number of sensing resources in the sensing resource set.

[0407] For example, the first information indicates the number of sensing resources C, i.e., indicates the number of sensing resources in the sensing resource set. That is, the first information indicates one sensing resource period, and the number of sensing resources is C. The sensing resource set indicated by the first information is the first sensing resource set.

[0408] For example, the first information indicates the number of sensing resources C. The number of sensing resources C indicates the number of sensing resources in the first sensing resource set.

[0409] For another example, the first information indicates the number of sensing resources C and the number of sensing resource sets M, i.e., indicates the number of sensing resources C in the sensing resource set and the number of sensing resource sets M. The number of sensing resources in the M sensing resource sets is the same, which is C. That is, the first information indicates one sensing resource period, and the sensing resource period is P2. The sensing resource set indicated by the first information includes {sensing resource set 1, sensing resource set 2, …, sensing resource set m, …, sensing resource set M}.

[0410] For example, the first information indicates the number of sensing resources C. The number of sensing resources C indicates the number of sensing resources in the first sensing resource set and the number of sensing resources in the second sensing resource set.

[0411] For another example, the first information indicates M numbers of sensing resources C m , i.e., indicates the number of sensing resources C m in the M sensing resource sets. That is, the first information indicates M sensing resource periods, and the M sensing resource periods are P2 m (m = 1, 2, …, M) respectively. The number of sensing resource sets M can be determined by the number of sensing resources C m . The sensing resource set indicated by the first information includes {sensing resource set 1, sensing resource set 2, …, sensing resource set m, …, sensing resource set M}.

[0412] For example, the first information indicates two numbers of sensing resources C1 and C2. C mIf 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.

[0413] 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.

[0414] 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 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.

[0415] 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.

[0416] The first information can indicate P21, P22, C, G1, and G2. G mThe 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.

[0417] 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.

[0418] The first information can indicate P2, C1, C2, G1, and G2. G m The number of P2 is 2 (i.e., G1 and G2). mIf the number of the P2s is 2 (i.e. P21, P22), the first information indicates M=2 sets of sensing resources. Wherein P2 is the sensing resource period of the first and second sets of sensing resources, G1, G2 respectively indicate the information of the starting time domain unit of the first and second sets of sensing resources, and C1, C2 respectively indicate the number of sensing resources included in the first and second sets of sensing resources. According to P2 and C1, the period P11 of the first set of sensing resources can be determined, and the first set of sensing resources includes a set of time slots corresponding to P11 time starting from time slot t m , wherein time slot t m satisfies t m mod(P11)=G1. According to P2 and C2, the period P12 of the second set of sensing resources can be determined, and the second set of sensing resources includes a set of time slots corresponding to P12 time starting from time slot t m , wherein time slot t m satisfies t m mod(P12)=G2.

[0419] The first information can indicate P2, C, G1 and G2. G m is 2 (i.e. G1 and G2), and P2 m is 2 (i.e. P21, P22), the first information indicates M=2 sets of sensing resources. Wherein P2 is the sensing resource period of the first and second sets of sensing resources, G1, G2 respectively indicate the information of the starting time domain unit of the first and second sets of sensing resources, and C indicates the number of sensing resources included in the first and second sets of sensing resources. According to P2 and C, the period P1 of the first and second sets of sensing resources can be determined, and the first set of sensing resources includes a set of time slots corresponding to P1 time starting from time slot t m , wherein time slot t m satisfies t m mod(P1)=G1. The second set of sensing resources includes a set of time slots corresponding to P1 time starting from time slot t m , wherein time slot t m satisfies t m mod(P1)=G2.

[0420] The first information can also indicate sensing resource set period repetition information. For example, the sensing resource set repeats Y periods, or in other words, the number of sensing resource set periods is Y. For example, the first information can indicate the sensing resource set to repeat a period in one or more of the following ways:

[0421] Manner 1: The first information indicates the number of periodicity Y of the sensing resource set, Y is a positive integer. For example, taking the first sensing resource set as an example, the first information indicates the number of periodicity of the first sensing resource set, that is, the number of periodicity of the first sensing resource set.

[0422] The periodicity of the sensing resource set can be indicated semi-statically, and the sensing resource set is transmitted for Y periods. 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}.

[0423] For example, the first information indicates the number of periodicity Y, and the sensing resource set is disabled after Y periods. The sensing transmitter, for example, the first device, the second device, or other sensing transmitters, stops transmitting the sensing signal after Y periods of the sensing resource set. Alternatively, the fourth device can stop receiving the sensing signal after receiving Y periods of the sensing resource set.

[0424] The first information can configure the number of periodicity Y for each group of sensing resource sets. For example, two different first information respectively indicates the number of periodicity Y1 of the first sensing resource set and the number of periodicity Y2 of the second sensing resource set.

[0425] Alternatively, the first information can configure the number of periodicity Y of M groups of sensing resource sets. For example, in the same first information, the number of periodicity of the first sensing resource set and the second sensing resource set is indicated as Y. That is, the M groups of sensing resource sets correspond to the same number of periodicity Y.

[0426] Alternatively, the first information can also indicate the number of periodicity Y corresponding to the M groups of sensing resource sets respectively m That is, the M groups of sensing resource sets correspond to the respective number of periodicity. Wherein m is an integer, the value can be m = 1, 2, …, M or m = 0, 1, …, M-1. For example, in the same first information, Y1 and Y2 are indicated, indicating that the first sensing resource set is repeated for Y1 periods, and the second sensing resource set is repeated for Y2 periods.

[0427] Manner 2: The first information can indicate the starting time domain unit information and / or the ending time domain unit information of the sensing resource set. For example, taking the first sensing resource set as an example, the first information can indicate at least one of the following: the starting time domain unit of the first sensing resource set, or the ending time domain unit, wherein the starting time domain unit is used to activate or enable the periodicity repetition of the first sensing resource set, and the ending time domain unit is used to deactivate or disable the periodicity repetition of the first sensing resource set.

[0428] In the embodiments of the present application, in order to distinguish the starting time domain unit of the sensing resource set and the starting time domain unit of the sensing resource, the starting time domain unit of the sensing resource is referred to as a first starting time domain unit, and the starting time domain unit of the sensing resource set is referred to as a second starting time domain unit. Similarly, the ending time domain unit of the sensing resource is referred to as a first ending time domain unit, and the ending time domain unit of the sensing resource set is referred to as a second ending time domain unit.

[0429] The sensing resource set periodic repetition can be dynamically activated and deactivated. The first information can indicate the dynamic activation of the sensing resource set periodic repetition through the first field, and / or the deactivation of the sensing resource set periodic repetition through the first field. The value of the first field indicating the dynamic activation of the sensing resource set periodic repetition and the value of the first field indicating the deactivation of the sensing resource set periodic repetition can be different.

[0430] For example, the first field is a first value, indicating the starting time domain unit information of the sensing resource set, that is, starting (activating) the sensing resource set periodic repetition, wherein the starting (activating) of the sensing resource set periodic repetition can be understood as indicating the starting time domain unit of the sensing resource set.

[0431] For another example, the first field is a second value, indicating the ending time domain unit information of the sensing resource set, that is, ending (deactivating) the sensing resource set periodic repetition. The ending (deactivating) of the sensing resource set periodic repetition can be understood as indicating the ending time domain unit of the sensing resource set.

[0432] The first information can configure the starting time domain unit for each group of sensing resource sets. For example, two different first information respectively indicate the starting time domain unit K11 and the starting time domain unit K12, respectively representing starting (activating) the periodic repetition of the first sensing resource set at the starting time domain unit K11 and starting (activating) the periodic repetition of the second sensing resource set at the starting time domain unit K12.

[0433] Alternatively, the first information can configure a uniform starting time domain unit for M groups of sensing resource sets. For example, in the same first information, the starting time domain unit of the first sensing resource set and the starting time domain unit of the second sensing resource set are both indicated as K1. That is, the M groups of sensing resource sets correspond to the same starting time domain unit, that is, starting (activating) the periodic repetition of the sensing resource set at the same time unit (that is, the starting time domain unit K1).

[0434] Alternatively, the first information can also indicate that the M groups of sensing resource sets correspond to the starting time domain units K1 m That is, the M groups of sensing resource sets correspond to the respective starting time domain units K1 mwhere m is an integer, and the value can be 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 are indicated, respectively, to represent the starting (activation) of the periodic repetition of the first sensing resource set at the starting time domain unit K11 and the starting (activation) of the periodic repetition of the second sensing resource set at the starting time domain unit K12.

[0435] The first information can configure the ending time domain unit for each group of sensing resource sets. For example, 2 different first information respectively indicates the ending time domain unit K21 and the ending time domain unit K22, respectively, to represent the ending (deactivation) of the periodic repetition of the first sensing resource set at the ending time domain unit K21 and the ending (deactivation) of the periodic repetition of the second sensing resource set at the ending time domain unit K22.

[0436] Alternatively, the first information can configure a unified second ending starting time domain unit for the M groups of sensing resource sets. For example, in the same first information, the ending time domain unit of the first sensing resource set and the ending time domain unit of the second sensing resource set are both indicated as K2. That is, the M groups of sensing resource sets correspond to the same ending time domain unit, that is, the same time unit (i.e., the ending time domain unit K2) ends (deactivates) the periodic repetition of the sensing resource set.

[0437] Alternatively, the first information can also indicate that the M groups of sensing resource sets correspond to the ending time domain unit K2 m , that is, the M groups of sensing resource sets correspond to the respective ending time domain unit K2 m where m is an integer, and the value can be m = 1, 2, …, M or m = 0, 1, …, M-1. For example, in the same first information, the ending time domain unit K21 and the ending time domain unit K22 are indicated, respectively, to represent the ending (deactivation) of the periodic repetition of the first sensing resource set at the ending time domain unit K21 and the ending (deactivation) of the periodic repetition of the second sensing resource set at the ending time domain unit K22.

[0438] The first information can indicate the value of the first field of the M groups of sensing resource sets. The first field of the first sensing resource set is a first value, indicating the starting time domain unit of the first sensing resource set, that is, starting (activating) the periodic repetition of the sensing resource set m; and / or, the first field of the second sensing resource set is a second value, indicating the ending time domain unit information of the second sensing resource set, that is, ending (deactivating) the periodic repetition of the second sensing resource set.

[0439] The first information can indicate the period of the M groups of sensing resource sets.

[0440] 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.

[0441] 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.

[0442] 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.

[0443] 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 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 remaining NM sensing resource sets have a third value for the periodic field. This third value can be either all 0s or all 1s.

[0444] 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.

[0445] For another example, the first information can comprise N sensing resource set period fields, and the first information further indicates a number M of the sensing resource sets. The first M sensing resource set period fields of the N sensing resource set period fields respectively indicate sensing resource periods P1, P2, …, PM of the M sensing resource sets. m ,…,P M Or, the last M sensing resource set period fields of the N sensing resource set period fields respectively indicate sensing resource periods P1, P2, …, PM of the M sensing resource sets. m ,…,P M

[0446] Optionally, the first information can further indicate a first time domain offset L.

[0447] The first time domain offset L is used to indicate that a starting time domain unit of the sensing resource set (e.g., the first sensing resource set, etc.) is the first time domain unit, where the first time domain unit is a time domain unit after a time domain unit where the first information is located by a 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 first time domain offset L after the time domain unit where the first information is located.

[0448] Or, the first time domain offset is used to indicate that a starting time domain unit of the sensing resource set (e.g., the first sensing resource set, etc.) is after the first time domain unit, where the first time domain unit is a time domain unit after a time domain unit where the first information is located by a 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 offset L after the time domain unit where the first information is located.

[0449] Or, the first time domain offset is used to indicate that a starting time domain unit of the sensing resource set (e.g., the first sensing resource set, etc.) is a starting time domain unit of a first sensing resource set after the first time domain unit, where the first time domain unit is a time domain unit after a time domain unit where the first information is located by a 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.

[0450] Optionally, the first time domain offset can comprise a time for processing the first information, a time for generating a sensing signal, and / or a waiting time, etc.

[0451] Optionally, the first information can further indicate a second time domain offset O.

[0452] The second time domain offset is used to indicate that the ending time domain unit of the sensing resource set, e.g., the first sensing resource set, is the second time domain unit after the first information is located in the time domain unit, where the second time domain unit is the time domain unit after the first information is located in the time domain unit by the second time domain offset. That is, the second time domain offset O indicates that the ending time domain unit of the sensing resource set is the second time domain unit after the first information is located in the time domain unit by the second time domain offset O.

[0453] Alternatively, the second time domain offset is used to indicate that the ending time domain unit of the sensing resource set, e.g., 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 first information is located in the time domain unit by the second time domain offset. That is, alternatively, the second time domain offset O indicates that the ending time domain unit of the sensing resource set is after the second time domain unit after the first information is located in the time domain unit by the second time domain offset O.

[0454] Alternatively, the second time domain offset is used to indicate that the ending time domain unit of the sensing resource set, e.g., the first sensing resource set, is the ending time domain unit of the first sensing resource set after the second time domain unit, where the second time domain unit is the time domain unit after the first information is located in the time domain unit by the second time domain offset. That is, the second time domain offset O indicates that the ending time domain unit of the sensing resource set is the ending time domain unit of the first sensing resource set after the second time domain unit after the first information is located in the time domain unit by the second time domain offset O.

[0455] Optionally, the second time domain offset includes a time for processing the first information, a cancellation sensing signal sending, and / or a waiting time.

[0456] Optionally, the first information can indicate the first time domain offset L of the sensing resource set alone or indicate the first time domain offset L of M groups of sensing resource sets collectively.

[0457] Optionally, the first information can indicate the first time domain offset L of the sensing resource set alone or indicate the first time domain offset L of M groups of sensing resource sets collectively.

[0458] Optionally, the first information can indicate the first time domain offset L of the sensing resource set alone or indicate the first time domain offset L of M groups of sensing resource sets collectively.

[0459] Optionally, the first information can indicate the first time domain offset L of the sensing resource set alone or indicate the first time domain offset L of M groups of sensing resource sets collectively. m Optionally, the first information can indicate the first time domain offset L of the sensing resource set alone or indicate the first time domain offset L of M groups of sensing resource sets collectively. mwherein m is an integer, and can take values of m = 1, 2, …, M or m = 0, 1, …, M-1. For example, in the same first information, L1 and L2 are indicated, which represent 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.

[0460] If the first information indicates the first time domain offset L uniformly (i.e., the above-mentioned manner A-2), the first time domain offset L can represent the starting time domain unit of the first set of sensing resources after the first time domain offset L after the time domain unit where the first information is located, among the M starting time domain units of the M sets of sensing resources. Taking the first time domain offset L of the first set of sensing resources as an example, the corresponding set of sensing resources of the first starting time domain unit is the first set of sensing resources.

[0461] Optionally, the first information can indicate the second time domain offset O of the set of sensing resources separately, or can indicate the second time domain offset O of the M sets of sensing resources uniformly.

[0462] Manner B-1, the first information can indicate the second time domain offset O for each set of sensing resources. For example, two different first information respectively indicate the second time domain offset value of the first set of sensing resources and the second set of sensing resources.

[0463] Manner B-2, the first information can indicate the second time domain offset O of the M sets of sensing resources uniformly. For example, in the same first information, the second time domain offset O of the first set of sensing resources and the second set of sensing resources is indicated. That is, the value of the second time domain offset of each set of sensing resources is O, and the M sets of sensing resources correspond to the same second time domain offset O.

[0464] Manner B-3, the first information can also indicate the second time domain offset O corresponding to the M sets of sensing resources respectively m That is, the M sets of sensing resources correspond to the respective second time domain offset O m wherein m is an integer, and can take values of m = 1, 2, …, M or m = 0, 1, …, M-1. For example, in the same first information, O1 and O2 are indicated, which represent the second time domain offset of the first set of sensing resources and the second time domain offset of the second set of sensing resources, respectively.

[0465] If the first information indicates the second time domain offset O uniformly (manner B-2), the second time domain offset O represents the ending time domain unit of the first set of sensing resources after the second time domain offset O after the time domain unit where the first information is located, among the M ending time domain units of the M sets of sensing resources. Taking the first time domain offset L of the first set of sensing resources as an example, the corresponding set of sensing resources of the first ending time domain unit is the first set of sensing resources.

[0466] Optionally, the first information can also respectively indicate a first time domain offset L of the M groups of sensing resource sets m and / or a second time domain offset O m , where m is an integer, and can take values of m = 1, 2, …, M or m = 0, 1, …, M-1.

[0467] For example, the first information can indicate a first time domain offset L of the sensing resource set m m , i.e., respectively indicating a first time domain offset of the M sensing resource sets. The first time domain offset L m represents a starting time domain unit of the sensing resource set m after a first time domain offset L of the starting time domain unit of the first information.

[0468] The first information can indicate a second time domain offset O of the sensing resource set m m , i.e., respectively indicating a second time domain offset of the M sensing resource sets. The second time domain offset O m represents an ending time domain unit of the sensing resource set m after a second time domain offset O of the ending time domain unit of the first information.

[0469] The above introduces the content of the first information indicating the time domain resources of the sensing resource set. Optionally, the first device, the second device, the third device, the fourth device, and other devices receiving the first information can determine the time domain resources of the sensing resource set according to the content indicated by the first information, for example, can determine the time domain resources of the sensing resource set according to at least two of the sensing resource set period, the sensing resource set starting time domain unit information (i.e., the first parameter), the sensing resource set ending time domain unit information (i.e., the second parameter), and the number M of sensing resource sets. Specifically, the determination manner of the sensing resource set period, the sensing resource set starting time domain unit information (the first parameter), the sensing resource set ending time domain unit information (the second parameter), and the number M of sensing resource sets is as above, any one of the above manners or other manners outside the present application can be adopted, and the present application does not make any limitation.

[0470] In a possible manner, the first information can also indicate the frequency domain resources of the sensing resource set. The first information can directly indicate the frequency domain resources of the sensing resource set, or indirectly indicate the frequency domain resources of the sensing resource set by indicating the frequency domain resources of the sensing resource.

[0471] Five ways of directly indicating the frequency domain resources of the sensing resource set are introduced below.

[0472] Method A: The first information can indicate the starting frequency domain unit of the sensing resource set and the number of frequency domain units of the sensing resource set.

[0473] 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.

[0474] In method C, the first information can indicate the starting frequency domain unit and the ending frequency domain unit of the sensing resource set.

[0475] In method D, the first information can indicate the starting frequency domain unit and the frequency domain width of the sensing resource set.

[0476] 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.

[0477] The following introduces three ways to indirectly indicate the frequency domain resources of a set of perceived resources.

[0478] 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.

[0479] 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.

[0480] 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.

[0481] 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.

[0482] 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:

[0483] The first information indicates at least two of: a starting frequency domain unit of the first sensing resource set, an ending frequency domain unit of the first sensing resource set, or a number of frequency domain units included in the first sensing resource set;

[0484] Alternatively, the first information indicates a starting frequency domain unit of the first sensing resource set, a number of frequency domain units included in the first sensing resource set, or a number of frequency domain units of adjacent frequency domain unit intervals in the first sensing resource set;

[0485] Alternatively, the first information indicates at least two of: a starting frequency domain unit of the first sensing resource set, an ending frequency domain unit of the first sensing resource set, or a frequency domain width of the first sensing resource set;

[0486] Alternatively, the first information indicates a number of frequency domain units of the first sensing resource;

[0487] Alternatively, the first information indicates a number of frequency domain units of the first sensing resource and a number of frequency domain units of adjacent frequency domain unit intervals in the first sensing resource.

[0488] The first information can also indicate a starting frequency domain unit of the sensing resource set, for example, the first information can indicate a value H m of the second parameter of the sensing resource set m as the first sensing resource set. For example, the first information can indicate a value H a of the second parameter of the sensing resource set m as the second sensing resource set. b

[0489] Optionally, the sensing configuration end can indicate the number M of sensing resource sets through the first information. For example, the first information can directly indicate the number M of sensing resource sets. For another example, the number M of sensing resource sets can be indicated through the number of H m in the first information. For another example, the number M of sensing resource sets can be indicated through the number of D m in the first information. This way can be suitable for the scenario that M groups of sensing resource sets correspond to respective numbers of frequency domain units. For another example, the number M of sensing resource sets can be indicated through the number of E m in the first information. This way can be suitable for the scenario that M groups of sensing resource sets correspond to respective numbers of frequency domain units of sensing resources. For another example, the number M of sensing resource sets can be indicated through the number of F m in the first information. This way can be suitable for the scenario that M groups of sensing resource sets correspond to respective frequency domain intervals between every two frequency domain units of sensing resources.

[0490] ​In another implementation, the first information can indicate the second parameter H or H m .

[0491] For example, the first information indicates the value H of the second parameter. That is, the first information indicates 1 second parameter, and the value of the second parameter is H. The set of sensing resources indicated by the first information is the first set of sensing resources, which is 1 set of sensing resources.

[0492] For example, the first information indicates the value H of the second parameter. The second parameter indicates information of a starting frequency domain unit of the first set of sensing resources. The first set of sensing resources includes D frequency domain units starting from the frequency domain unit f m , where the frequency domain unit f m satisfies f m mod(D) = H. D is the number of frequency domain units included in the first set of sensing resources.

[0493] For another example, the first information indicates the value H of the second parameter and the number M of sets of sensing resources. That is, the first information indicates 1 second parameter, and the value of the second parameter is H. The values of the second parameters of the M sets of sensing resources are the same, and are all H. The set of sensing resources indicated by the first information includes {set of sensing resources 1, set of sensing resources 2, …, set of sensing resources m, …, set of sensing resources M}.

[0494] For example, the first information indicates the value H of the second parameter. The second parameter indicates information of a starting frequency domain unit of the first set of sensing resources and information of a starting frequency domain unit of the second set of sensing resources. The first set of sensing resources includes D1 frequency domain units starting from the frequency domain unit f m , where the frequency domain unit f m satisfies f m mod(D1) = H. The second set of sensing resources includes D2 frequency domain units starting from the frequency domain unit f m , where the frequency domain unit f m satisfies f m mod(D2) = H. D1 and D2 can be the same or different, and the present example does not limit this.

[0495] For another example, the first information indicates the values H m of M second parameters. That is, the first information indicates M second parameters, and the values of the M second parameters are H m (m = 1, 2, …, M) respectively. The number M of sets of sensing resources can be determined by the number of second parameters H m . The set of sensing resources indicated by the first information includes {set of sensing resources 1, set of sensing resources 2, …, set of sensing resources m, …, set of sensing resources M}.

[0496] 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.

[0497] 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.

[0498] 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.

[0499] 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 fm satisfies f m mod(D1) = H1. The second set of sensing resources includes a set of D2 RBs starting from the RE with index f m satisfies f m mod(D2) = H2. m satisfies f m mod(D2) = H2.

[0500] The first information can indicate E, F, H1 and H2. If the number of H m satisfies f m mod(D1) = H1. The second set of sensing resources includes a set of D2 RBs starting from the RE with index f m satisfies f m mod(D2) = H2. m satisfies f m mod(D2) = H2.

[0501] The first information can indicate E1, E2, F1, F2, H1 and H2. If the number of F m satisfies f m satisfies f m satisfies f m mod(D1) = H1. The second set of sensing resources includes a set of D2 RBs starting from the RE with index f m satisfies f m mod(D2) = H2. mA set of D RBs starting with RE, where index f m Satisfy f m mod(D2) = H2.

[0502] The first information can indicate E, F1, F2, H1, and H2. F m The number of H is 2 (i.e., F1, F2). 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, 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.

[0503] 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 fm mod(D2) = H2.

[0504] According to the foregoing, the first information can indicate at least one of the following information: time domain start information G m of the sensing resource set, sensing resource set period P1 or P1 m , starting time domain unit of the sensing resource set, ending time domain unit of the sensing resource set, number C or C m of sensing resources within the sensing resource set, sensing resource period P2 or P2 m , number Y or Y m of sensing resource set periods, first field 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 start information H m of the sensing resource set, number D or D m of frequency domain units included in the sensing resource set, starting frequency domain unit of the sensing resource set, ending frequency domain unit of the sensing resource set, frequency domain width I or I m of the sensing resource set, frequency domain interval J or J m between every two frequency domain units in the sensing resource set, number E or E m of frequency domain units of sensing resources within the sensing resource set, frequency domain interval F or F m between every two frequency domain units of the sensing resource, number M of sensing resource sets, sensing resource set period repetition information, first power adjustment value, or second power adjustment value. The sensing resource set period repetition information is the starting time domain unit of the sensing resource set and / or the ending time domain unit of the sensing resource set. The first information indicates the first field, which can also be described as the first information indicating the starting time domain unit information of the sensing resource set and / or the ending time domain unit information of the sensing resource set.

[0505] The above information can be indicated for one set of sensing resources or for M sets of sensing resources. For example, in the case of periodic repetition indicated by the first information, the first information can indicate periodic repetition for one set of sensing resources, such as the first set of sensing resources, or for M sets of sensing resources. The specific manner can refer to the above manner 1 and manner 2, and it should be noted that manner 1 and manner 2 are indicated for one set of sensing resources. If M sets of sensing resources are indicated, the first information can indicate M sets of sensing resources in a similar manner. As can be understood from the foregoing description, M sets of sensing resources can correspond to one parameter value or to respective parameter values for one parameter, such as the period of the set of sensing resources, the period of the sensing resource, the number of sensing resources, the number of frequency domain units of the set of sensing resources, and the like. Therefore, in the case where M sets of sensing resources correspond to one parameter value for one parameter, the first information can be uniformly configured for M sets of sensing resources. In the case where M sets of sensing resources correspond to respective parameter values for one parameter, the first information can be configured for M sets of sensing resources respectively. The specific indication manner can be combined with the related description of each parameter in the foregoing, which will not be described one by one here.

[0506] In this application, the first information can be configured or preconfigured, or part of the content indicated by the first information can be configured or preconfigured. For example, the first information can be sent by a third device to the first device, the second device, or the fourth device. In this way, the third device is different 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 way, the first device can directly obtain the first information without receiving the first information. Alternatively, the first information can be sent by the fourth device to the first device or the second device, that is, the third device and the fourth device are the same device. In this way, the fourth device can directly obtain the first information without receiving the first information.

[0507] The first information can be preset, or part of the content indicated by the first information can be preset. For example, the protocol is preset. In this way, S401 and S402 can not be performed.

[0508] The first information can be semi-statically indicated or dynamically activated and deactivated.

[0509] Manner 1: The first information can be carried by RRC or MAC CE.

[0510] For example, the first information is carried by a MAC CE, and an LCID of a MAC subheader of the MAC CE can be a fourth value. The MAC CE can indicate configuring (reconfiguring) a set of sensing resources. The fourth value can be any integer from 35 to 46.

[0511] For example, the first information is carried by a MAC CE, and an LCID of a MAC subheader of the MAC CE can be a fifth value. The MAC CE can indicate releasing a set of sensing resources. The fifth value can be any integer from 35 to 46.

[0512] Option 2: The first information can be carried by a DCI or a SCI.

[0513] For example, the dynamic activation of a set of sensing resources can be indicated by a first field included in the DCI or the SCI. For another example, the deactivation of a set of sensing resources can be indicated by a first field included in the DCI or the SCI. For details, refer to the foregoing description, which will not be repeated here.

[0514] In the present application, the first information can be scrambled by a first RNTI. The first RNTI can be a RNTI for sensing, or a RNTI dedicated to sensing. That is, the first device, the second device, and the fourth device can all decode the first information by the first RNTI.

[0515] In the present application, activation can be understood as starting, enabling, configuring, etc., and the above terms can be replaced synonymously. Deactivation can be understood as ending, disabling, releasing, etc., and the above terms can be replaced synonymously.

[0516] S402, the third device sends the first information. Correspondingly, the first device receives the first information.

[0517] The first information is used to configure a first set of sensing resources, and the first set of sensing resources includes periodically repeated first sensing resources.

[0518] Optionally, according to the foregoing description, the second device can also receive the first information, and the first information can also configure the first set of sensing resources for the second device.

[0519] Optionally, the second device can also receive the first information. For example, the first device and the fourth device belong to different devices, and the fourth device can receive the above-mentioned first information before receiving the first sensing signal on the first sensing resource.

[0520] S403, the first device sends a first sensing signal on the first sensing resource. Correspondingly, the fourth device receives the first sensing signal on the first sensing resource.

[0521] The first sensing signal is used to determine the information of the sensing target. The determination of the information of the sensing target can also be referred to as running a sensing service, or simply as sensing.

[0522] The information of the sensing target includes at least one of the following: motion information of the sensing target, motion change information of the sensing target, distance information of the sensing target, speed information of the sensing target, and angle information of the sensing target. That is, the determination of the information of the sensing target can be replaced by the determination of at least one of the motion information, the motion change information, the distance information, the speed information, and the angle information.

[0523] The first device transmits the first sensing signal, and the third device receives and / or processes the first sensing signal. The first sensing signal is used to determine the information of the sensing target. It can be understood that the third device processes the first sensing signal to determine the information of the sensing target, and the first sensing signal transmitted by the first device is for the third device to determine the information of the sensing target.

[0524] According to the foregoing description, the first information can also configure the first sensing resource set for the second device. Therefore, the second device can also transmit a second sensing signal on the first sensing resource set. The second sensing signal is used to determine the information of the sensing target, or the second sensing signal is used to assist in determining the information of the sensing target. It can be understood that the third device processes the second sensing signal to determine the information of the sensing target, and the second sensing signal transmitted by the second device is for the third device to determine the information of the sensing target, or the second sensing signal transmitted by the second device is for the third device to assist in determining the information of the sensing target.

[0525] Optionally, the fourth device can receive the second sensing signal on the first sensing resource. It can be understood that the fourth device receives the sum signal of the first sensing signal and the second sensing signal. That is, the sum signal of the first sensing signal and the second sensing signal can be used to determine the information of the sensing target.

[0526] Optionally, if the first device and the fourth device belong to the same device, the first device and / or the fourth device can directly determine the above-mentioned first information.

[0527] Optionally, if the first device and the fourth device belong to different devices, the fourth device can receive the above-mentioned first information before receiving the first sensing signal on the first sensing resource. For example, the first information is received from the first device or the third device.

[0528] Optionally, the second device can also receive the above-mentioned first information before transmitting the second sensing signal on the first sensing resource. For example, the first information is received from the first device or the third device.

[0529] In a possible implementation, the first device can specifically transmit the first sensing signal on each first sensing resource included in the first set of sensing resources. In this implementation, each first sensing resource included in the first set of sensing resources carries the sensing signal. Alternatively, it can also be described that, within the first set of sensing resources, the first device starts transmitting the first sensing signal at the starting time domain unit of the first sensing resource and ends at the ending time domain unit of the first sensing resource. It can also be described that the first sensing signal is transmitted on the time domain unit where each first sensing resource included in the first set of sensing resources is located.

[0530] The first device can transmit the first sensing signal on each first sensing resource included in the first set of sensing resources when it needs to transmit the sensing signal or perform the sensing service.

[0531] In another possible implementation, the first device can specifically transmit the first sensing signal on each first sensing resource included in the first time period. In this implementation, each first sensing resource included in the first time period carries the sensing signal.

[0532] The first device can transmit the first sensing signal on each first sensing resource included in the first time period when it needs to transmit the sensing signal or perform the sensing service.

[0533] In another possible implementation, the first device can specifically transmit the first sensing signal on each first sensing resource included in at least one cycle of the periodically-recurring first set of sensing resources. In this implementation, each first sensing resource included in at least one cycle of the periodically-recurring first set of sensing resources carries the sensing signal.

[0534] The first device can transmit the first sensing signal on each first sensing resource included in at least one cycle of the periodically-recurring first set of sensing resources when it needs to transmit the sensing signal or perform the sensing service.

[0535] For example, the first device can transmit the first sensing signal on each first sensing resource included in the first H cycles of the periodically-recurring first set of sensing resources, i.e., each first sensing resource included in the first H cycles of the first set of sensing resources carries the sensing signal. For example, assuming that the first device periodically recurs for 3 times, the first device can transmit the first sensing signal on each first sensing resource included in the first and second cycles of the first set of sensing resources, i.e., each first sensing resource included in the first and second cycles of the first set of sensing resources carries the sensing signal.

[0536] In the three implementation manners above, the first sensing signal is transmitted on each first sensing resource included in the first sensing resource set, or the first sensing signal is transmitted on the time domain unit in which each first sensing resource included in the first sensing resource set is located. It can also be understood that, on the first sensing resource set including the first sensing resource, the sensing signal transmission on any first sensing resource is not discarded, or it is not expected to be discarded.

[0537] It can be understood that the first sensing resource set includes the first sensing resource and other resources. On the other resources, the first device can not transmit, for example, can not transmit the first sensing signal.

[0538] In the sensing resource set, the first device and / or the second device starts to transmit the sensing signal at the starting time domain unit of the sensing resource, and stops transmitting the sensing signal at the ending time domain unit of the sensing resource. It can be understood that the sensing signal is not started to be transmitted at the non-starting time domain unit of the sensing resource in the sensing resource set, and the sensing signal is not stopped to be transmitted at the non-ending time domain unit of the sensing resource in the sensing resource set.

[0539] The first sensing signal is transmitted on each first sensing resource included in at least one period of the periodically repeated first sensing resource set. It can be understood that, in at least one period of the periodically repeated first sensing resource set, the first sensing signal is started to be transmitted at the starting time domain unit of each first sensing resource, and stopped to be transmitted at the ending time domain unit of each first sensing resource.

[0540] It should be noted that the three implementation manners above are expected transmission manners of the sensing signal. In specific implementation, the first device can not occupy each sensing resource when transmitting the sensing signal, for example, one or more sensing resources are occupied by other devices, and the like. The present application does not exclude the occurrence of these situations.

[0541] Optionally, the third device can enable the first device to skip the transmission of the first sensing signal on one or more first sensing resources in the first sensing resource set. For example, when the number of candidate transmitted communication signals and / or the number of candidate transmitted sensing signals of the first device is greater than or equal to the maximum concurrency, the first device can skip the transmission of the first sensing signal on one or more first sensing resources in the first sensing resource set. The candidate transmitted communication signal can also be understood as the to-be-transmitted communication signal, and the candidate transmitted sensing signal can also be understood as the to-be-transmitted sensing signal.

[0542] Further, the first device and the second device can transmit the sensing signal on the same resource, thereby increasing the signal-to-noise ratio of the first device receiving the sensing signal. That is, the second device assists the first sensing transmission end to transmit the sensing signal. This is beneficial to expand the coverage of sensing and increase the reliability of sensing.

[0543] Optionally, the transmission power of the first device for transmitting the first sensing signal on the first sensing resource in the second time period is kept unchanged. It can also be described as that the first device transmits the sensing signal on the first sensing resource with the same transmission power in the second time period. For other sensing resource sets (e.g., periodic repetition of the first sensing resource set), the transmission power of the first device for transmitting the sensing signal on the sensing resource can be changed or unchanged, i.e., the transmission power of the first device can be changed or unchanged between different sensing resource sets.

[0544] Transmitting the first sensing signal with the same transmission power includes that, 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 with the same at least one of the following parameters: the same P0 parameter, the same path loss compensation factor a, the same path loss estimation value PL, the same maximum transmit power P CMAX . Wherein P0 is a P0 parameter for power control, which can be understood as an initial value of uplink transmission power, and is essentially an expected received power.

[0545] Or it can be described that, when transmitting the first sensing signal on the time domain unit where each first sensing resource within the first sensing resource set is located, the first device transmits the first sensing signal on the time domain unit where each first sensing resource is located with the same at least one of the following parameters: the same P0 parameter, the same path loss compensation factor a, the same path loss estimation value PL, the same maximum transmit power P CMAX .

[0546] Optionally, the transmission power of the at least two sensing transmitters for transmitting the sensing signal on the first sensing resource set in the second time period is kept unchanged. An example is that the transmission power of each sensing transmitter for transmitting the sensing signal on the first sensing resource set is kept unchanged. For example, the transmission power of the first device and the second device for transmitting the first sensing signal on the first sensing resource is kept unchanged. It can also be described as that, in the second time period, each sensing transmitter (e.g., the first device and the second device) transmits the sensing signal on the first sensing resource with the same transmission power. For other sensing resource sets (e.g., periodic repetition of the first sensing resource set), the transmission power of the sensing transmitter for transmitting the sensing signal on the sensing resource can be changed or unchanged, i.e., the transmission power can be changed or unchanged between different sensing resource sets.

[0547] The first device and the second device transmit the first sensing signal with the same sending power includes that, 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 with the same at least one of the following parameters: the same P0 parameter, the same path loss compensation factor α, the same path loss estimation value PL, and the same maximum transmission power P CMAX . Wherein, P0 is a P0 parameter for power control, which can be understood as an initial value of uplink sending power, and is essentially an expected receiving power.

[0548] Or, it is described that, when transmitting the first sensing signal on the time domain unit where each first sensing resource within the first sensing resource set is located, the first device and the second device use the same at least one of the following parameters on the time domain unit where each first sensing resource is located: the same P0 parameter, the same path loss compensation factor α, the same path loss estimation value PL, and the same maximum transmission power P CMAX .

[0549] Correspondingly, the sensing receiving end can determine that the sending power of the sensing signal of each sensing sending end (for example, the first device and the second device) on the first sensing resource set remains unchanged within the second time period.

[0550] Suppose that the first device and the second device transmit the sensing signal on the first sensing resource set, and the sending power of the sensing signal transmitted by the two devices is unchanged (for example, both are 100 dBm), so that the third device sensing receiving end receives a changed sensing signal (for example, 80-85 dBm), it can be determined that the change of the power of the sensing signal is caused by the movement of the sensing target and the like, and the information of the sensing target is determined according to the change of the sensing signal. Conversely, if the sending power of the second device changes, the fourth device cannot determine whether the change of the received sensing signal is caused by the movement of the sensing target or the second device, so as to affect the accuracy and reliability of the sensing result. Through the above-mentioned manner, it can be ensured that the influencing factor of the change of the sensing signal within the first time period Tw or the first sensing resource set is only the movement of the sensing target and the like. Thus, the influence of different sensing sending ends on each other can be avoided.

[0551] In another possible manner, the change of the transmission power of the sensing signal transmitted by the at least two sensing transmitters (e.g., the first device and the second device) on the first set of sensing resources is the same in the second time period. An example is that the change of the transmission power of the sensing signal transmitted by each of the at least two sensing transmitters (e.g., the first device and the second device) on the first set of sensing resources is the same. For example, the first device and the second device both transmit the first sensing signal on the first sensing resource, and the change of the transmission power of the first sensing signal transmitted by the first device on the first sensing resource is the same as the change of the transmission power of the second sensing signal transmitted by the second device on the first sensing resource. That is, the transmission power of the first device and the second device on the first set of sensing resources can be different, but the change of the transmission power is the same.

[0552] The first device and the second device transmit the sensing signal on the same first sensing resource. That is, the first device and the second device transmit the sensing signal on the same first sensing resource in the same first set of sensing resources. For example, the first device transmits the first sensing signal on the first sensing resource in the fourth time domain unit and the first sensing resource in the fifth time domain unit. The second device transmits the second sensing signal on the first sensing resource in the fourth time domain unit and the first sensing resource in the fifth time domain unit. Wherein, the first device transmits the first sensing signal on different first sensing resources with different transmission power, that is, the first device transmits the first sensing signal on the fourth time domain unit and the fifth time domain unit with different transmission power. Correspondingly, the second device also transmits the second sensing signal on the fourth time domain unit and the fifth time domain unit with different transmission power.

[0553] The first power adjustment value of the first device and the second power adjustment value of the second device are the same. Wherein, the first power adjustment value is the change of the transmission power of the sensing signal transmitted by the first device on the fourth time domain unit and the fifth time domain unit, and the second power adjustment value is the change of the transmission power of the sensing signal transmitted by the second device on the fourth time domain unit and the fifth time domain unit. Specifically, the first power adjustment value can be the change of the transmission power of the sensing signal transmitted by the first device on the first sensing resource in the fourth time domain unit and the first sensing resource in the fifth time domain unit, and the second power adjustment value is the change of the transmission power of the sensing signal transmitted by the second device on the first sensing resource in the fourth time domain unit and the first sensing resource in the fifth time domain unit.

[0554] Wherein, the fourth time domain unit and the fifth time domain unit are two time domain units in which the sensing resources in the set of sensing resources are located. For example, they are adjacent or interval-adjacent two time domain units.

[0555] For example, the first power adjustment value of the transmission power of the first device on the second first sensing resource compared 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 compared to the transmission power on the first first sensing resource also needs to be X dB.

[0556] For another example, the first power adjustment value of the transmission power of the first device on the fifth time domain unit compared to the transmission power on the fourth time domain unit is X dB, and the first power adjustment value of the transmission power of the second device on the fifth time domain unit compared to the transmission power on the fourth time domain unit also needs to be X dB.

[0557] The first power adjustment value can include any one of the following: a transmission power adjustment value, a maximum transmit power P CMAX adjustment value, a P0 parameter adjustment value, a path loss compensation factor a adjustment value, and a path loss estimation value PL adjustment value. Similarly, the second power adjustment value can include any one of the following: a transmission power adjustment value, a maximum transmit power P CMAX adjustment value, a P0 parameter adjustment value, a path loss compensation factor a adjustment value, and a path loss estimation value PL adjustment value.

[0558] The first power adjustment value and the second power adjustment value are the same, which can be understood as: the transmission power adjustment value is the same, the maximum transmit power P CMAX adjustment value is the same, the P0 parameter adjustment value is the same, the path loss compensation factor a adjustment value is the same, and the path loss estimation value PL adjustment value is the same.

[0559] The second device can adjust the transmission power of the second device according to the first power adjustment value, that is, the change of the transmission power of the second device for transmitting the sensing signal on the fourth time domain unit and the fifth time domain unit is equal to the first power adjustment value. The first power adjustment value can be indicated by the first information or indicated by the first device through the third information. The first information or the third information indicates the change of the transmission power of the sensing signal or indicates the change mode of the transmission power of the sensing signal transmitted by other sensing transmitting ends. The first device can send the third information to other sensing transmitting ends such as the second device, the fourth device, and the like. Alternatively, the first device can send the third information to the network device (for example, the third device), and the network device (for example, the third device) indicates the change of the transmission power of the sensing signal transmitted on the first sensing resource to other sensing transmitting ends such as the second device, the fourth device, and the like.

[0560] Alternatively, the first device can adjust the transmission power of the first device according to the second power adjustment value, that is, the change of the transmission power of the first device for transmitting the sensing signal on the fourth time domain unit and the fifth time domain unit is equal to the second power adjustment value.

[0561] Alternatively, the second power adjustment value can be indicated by the first information or indicated by the second device through the fourth information. The first information or the fourth information indicates a change of the transmission power of the second sensing signal or indicates a change manner of the transmission power of the sensing signal transmitted by the other sensing transmitter. The second device can send the fourth information to the other sensing transmitter, such as the first device, etc., the fourth device. Alternatively, the second device can send the fourth information to the network device (such as the third device), and the network device (such as the third device) indicates the change of the transmission power of the sensing signal transmitted on the first sensing resource to the other sensing transmitter, such as the first device, etc., the fourth device.

[0562] Correspondingly, the fourth device can determine that the change of the transmission power of the sensing signal transmitted by each sensing transmitter on the first set of sensing resources is the same in the second time period. Optionally, the change of the transmission power of the sensing signal transmitted by each sensing transmitter on the first set of sensing resources can be determined according to the third information.

[0563] Correspondingly, the fourth device can determine the information of the sensing target based on the first power adjustment value. For example, the fourth device can remove the part of the change of the sensing signal caused by the first power adjustment value in the process of signal processing based on the first power adjustment value indicated by the first information or the third information, and then determine the information of the sensing target.

[0564] Suppose there are two sensing transmitters (the first device and the second device) transmitting sensing signals on the first set of sensing resources, and the change of the transmission power of the sensing signal transmitted by the two sensing transmitters on the first set of sensing resources is the same. For example, the transmission power of the sensing signal transmitted by the two sensing transmitters on the fourth time domain unit is unchanged (for example, both are 100 dBm), so the fourth device receives the changed sensing signal (for example, 80-85 dBm); the transmission power of the sensing signal transmitted by the two sensing transmitters on the fifth time domain unit is 50 dBm, so the fourth device receives the changed sensing signal (for example, 30-35 dBm), and it can be determined that the change of the sensing signal from 80-85 dBm to 30-35 dBm is caused by the change of the transmission power of the first device on the fourth time domain unit and the fifth time domain unit, and the change of the transmission power of the second device on the fourth time domain unit and the fifth time domain unit. It can also be determined that the change of the sensing signal 85-80=5 dB (and 35-30=5 dB) is caused by the movement of the sensing target, and the information of the sensing target is determined according to the change of the sensing signal. Through the above-mentioned manner, the influence of the change of the transmission power of the sensing transmitter can be removed, so as to ensure that the influencing factors of the change of the sensing signal in the first time period Tw are only the movement of the sensing target and other factors as much as possible. Thus, the influence of different sensing transmitters on each other can be avoided.

[0565] For example, the second time period is the time domain resource of the first sensing resource set, or the time domain resource of the periodically repeated first sensing resource set.

[0566] For example, the time domain resource of the first sensing resource set and the second time period overlap, for example, the second time period can be equal to the time domain resource of the first sensing resource set. Or, the second time period includes the time domain resource of the first sensing resource set, for example, the second time period is an integer multiple of the time domain resource of the first sensing resource set. Or, the time domain resource of the first sensing resource set includes the second time period, for example, the time domain resource of the first sensing resource set is an integer multiple of the second time period.

[0567] For example, the first time period and the second time period overlap, for example, the second time period can be equal to the first time period. Or, the second time period includes the first time period, for example, the second time period is an integer multiple of the first time period. Or, the first time period includes the second time period, for example, the first time period is an integer multiple of the second time period.

[0568] Based on the above scheme, the sensing sending end such as the first device, the second device, or other sensing sending ends, etc., or the fourth device can determine the used sensing resource set according to the starting time domain unit of the M groups of sensing resource sets.

[0569] As described in S401, the first information can indicate the M groups of sensing resource sets, so that the sensing sending end such as the first device, the second device, or other sensing sending ends, etc., or the fourth device can determine the used sensing resource set in the M groups of sensing resource sets. The following describes the way of determining the first sensing resource set by taking the first device as an example.

[0570] The first sensing resource set is the sensing resource set with the earliest starting time domain unit in the M groups of sensing resource sets, that is, the closer to the starting time domain unit of which sensing resource set in the time domain, the closer to which sensing resource set to send the sensing signal. Or, the first sensing resource set is the sensing resource set in which the sensing resource with the earliest starting time domain unit is included in the M groups of sensing resource sets, that is, the closer to the starting time domain unit of which sensing resource in the time domain, the closer to which sensing resource set to send the sensing signal.

[0571] In Example 1, the first sensing resource set is the sensing resource set with the earliest starting time domain unit in the M groups of sensing resource sets after the third time domain unit; it can also be described as the first sensing resource set is the sensing resource set corresponding to the earliest starting time domain unit in the starting time domain units of the M groups of sensing resource sets after the third time domain unit.

[0572] In the example 2, the first set of sensing resources is a set of sensing resources corresponding to a starting time domain unit of a first sensing resource in M sets of sensing resources after the third time domain unit. In other words, the first set of sensing resources is a set of sensing resources corresponding to a starting time domain unit of a first sensing resource in M sets of sensing resources after the third time domain unit.

[0573] In the above two examples, the third time domain unit is a time domain unit triggering sensing, or the third time domain unit is a time domain unit after the time domain unit triggering sensing by a third time domain offset, or the third time domain unit is related to the time domain unit triggering sensing, or the third time domain unit is related to the time domain unit triggering sensing and the third time domain offset, or the third time domain unit is a time domain unit receiving the first information, or the third time domain unit is a time domain unit after the time domain unit receiving the first information by a third time domain offset, or the third time domain unit is related to the time domain unit receiving the first information, or the third time domain unit is related to the time domain unit receiving the first information and the third time domain offset.

[0574] In the example 1, the first set of sensing resources is a set of sensing resources corresponding to a starting time domain unit of a first sensing resource in M sets of sensing resources after the third time domain offset after the third time domain unit triggering sensing. In other words, the first set of sensing resources is a set of sensing resources corresponding to a starting time domain unit of a first sensing resource in M sets of sensing resources after the third time domain offset after the third time domain unit triggering sensing.

[0575] In the example 2, the first set of sensing resources is a set of sensing resources corresponding to a starting time domain unit of a first sensing resource in M sets of sensing resources after the third time domain offset after the third time domain unit triggering sensing. In other words, the first set of sensing resources is a set of sensing resources corresponding to a starting time domain unit of a first sensing resource in M sets of sensing resources after the third time domain offset after the third time domain unit triggering sensing.

[0576] Optionally, the first information can further indicate the third time domain offset Q. Optionally, a value of the third time domain offset is equal to the first time domain offset, or a value of the third time domain offset is equal to the first time domain offset by default. The third time domain offset can include a time of processing the first information, a time of generating a sensing signal, and / or a waiting time, etc.

[0577] Optionally, the third time domain unit can be the first time domain unit, or the third time domain unit is the first time domain unit by default.

[0578] The first sensing resource included in the first sensing resource set is a resource for transmitting the first sensing signal. That is, the time domain unit of the first sensing resource included in the first sensing resource set is a time domain unit for transmitting the first sensing signal; and / or, the frequency domain unit of the first sensing resource included in the first sensing resource set is a frequency domain unit for transmitting the first sensing signal.

[0579] The above introduces a scheme for transmitting a sensing signal on a sensing resource set. The following introduces a configuration subject of the sensing resource set.

[0580] As an optional scheme, the first information is used to configure a sensing resource set, for example, configure M groups of sensing resource sets, for at least one device, including at least one device for transmitting a sensing signal (such as the first device, the second device, etc.) and / or at least one device for receiving a sensing signal (such as the fourth device, etc.).

[0581] Optionally, in this application, a stationary device can transmit a sensing signal on a sensing resource set, and / or a non-stationary device cannot transmit a sensing signal on a sensing resource set. Alternatively, a device with a motion speed less than or equal to a first speed can transmit a sensing signal on a sensing resource set, and / or a device with a motion speed greater than or equal to a second speed cannot transmit a sensing signal on a sensing resource set, that is, the motion speed of the first device and the second device is less than or equal to the first speed. Wherein, the first speed is less than or equal to the second speed.

[0582] Correspondingly, the third device allocates a sensing resource set to a stationary device or a device with a motion speed less than or equal to a first speed. Based on this, at least one device for transmitting a sensing signal (such as the first device, the second device, etc.) involved in this application has a motion speed less than or equal to a threshold value. Wherein, the threshold value can be 0, that is, the above-mentioned at least one device for transmitting a sensing signal (such as the first device, the second device, etc.) is stationary. The threshold value can be the first speed, that is, the above-mentioned at least one device for transmitting a sensing signal (such as the first device, the second device, etc.) is a device with a motion speed less than or equal to the first speed.

[0583] The third device can determine that a device is stationary or determine that a device has a speed less than or equal to the first speed in any of the following four ways:

[0584] Method a: The device for transmitting a sensing signal (such as the first device, the second device, etc.) and / or the device for receiving a sensing signal (such as the fourth device, etc.) reports its state as stationary or non-stationary.

[0585] Method b: The device for transmitting a sensing signal (such as the first device, the second device, etc.) and / or the device for receiving a sensing signal (such as the fourth device, etc.) reports its state as a motion speed less than or equal to the first speed or a motion speed greater than or equal to the second speed.

[0586] Option c: the third device measures the signal energy of the device (e.g., the first device, the second device, etc.) that transmits the sensing signal and / or the device (e.g., the fourth device, etc.) that receives the sensing signal.

[0587] Option d: the third device measures the variance of the signal energy of the device (e.g., the first device, the second device, etc.) that transmits the sensing signal and / or the device (e.g., the fourth device, etc.) that receives the sensing signal, and the variance is less than a first signal energy threshold.
