Description

A resource allocation method and related apparatus

[0001] This application claims priority to Chinese Patent Application No. 202510091996.X, filed on January 17, 2025, entitled “A Resource Allocation Method and Related Apparatus”, the entire contents of which are incorporated herein by reference. Technical Field

[0002] This application relates to the field of communication technology, and in particular to a resource allocation method and related apparatus. Background Technology

[0003] In the current field of communication technology, the integration of communication and sensing (also known as sensing) is an important technological direction. Communication systems possess sensing capabilities, achieving integrated design of communication and sensing. Similar to Long Term Evolution (LTE) / New Radio (NR) communication systems, sensing does not require a separate sensing network deployment or customized terminals, resulting in low deployment, usage, and maintenance costs. Sensing functionality relies on network and terminal capabilities, continuously iterating and evolving.

[0004] The integration of communication and sensing takes various forms, such as using communication signals to perform sensing functions or using sensing results to assist communication. Sensing functions include target detection. Sensing targets include unmanned aerial vehicle (UAV) targets, human targets, automotive vehicles, automated guided vehicles, and objects creating hazards on roads / railways. Within the framework of sensing scenarios and the integration of communication and sensing, the transmission of sensing signals often relies on specific temporal resources, which are independent of the temporal resources of communication signals. This means that the transmission of sensing signals may crowd out communication signal resources. Summary of the Invention

[0005] This application provides a resource allocation method and related apparatus to improve the resource utilization rate of transmitted sensing signals without affecting the transmission of communication signals.

[0006] Firstly, this application provides a resource allocation method, which is executed by a first device. The first device can be a device capable of transmitting sensing signals. For example, the first device is a terminal device or a component within a terminal device, such as a chip. Alternatively, the first device is a network device or a component within a network device, such as a chip. This application does not impose any limitations on this. The following description uses the first device as the executing entity to illustrate the above resource allocation method, whereby the first device can perform the following operations:

[0007] The first device acquires at least one of the following time-domain resources: a first time-domain resource, a second time-domain resource, or a third time-domain resource; wherein the first time-domain resource is located after the first downlink time unit and / or before the first uplink time unit in the time domain, and the second time-domain resource is located after the second uplink time unit and / or before the second downlink time unit in the time domain; the third time-domain resource is located after the last communication symbol in the third time unit, or before the first communication symbol in the third time unit, or the time-domain resource of one or more cyclic prefixes in the third time unit includes the third time-domain resource; the first device transmits a sensing signal on at least one of the following time-domain resources: the first time-domain resource, the second time-domain resource, or the third time-domain resource.

[0008] This application provides a resource allocation method executed by a first device, which allows the first device (such as a terminal device) to transmit sensing signals on specific time-domain resources. Considering that current communication technologies do not allocate dedicated resources for sensing signals, and there are no resources specifically for sensing in the prior art, the method provided in this application enables sensing signals to be transmitted on time-frequency resources not used for transmitting uplink or downlink information in existing protocols. For example, the time interval between uplink and downlink time slots, the time interval between downlink and uplink time slots, and the time interval between symbols are all potential resources that can be used to transmit sensing signals. This flexible resource allocation method allows the device to effectively utilize time-domain resources for sensing operations without affecting normal communication, thereby improving the system's resource utilization and sensing efficiency. Since no communication signals are transmitted on the aforementioned time intervals, transmitting sensing signals in these intervals does not affect communication performance and makes reasonable use of resources.

[0009] It is understood that the aforementioned uplink time unit refers to a time unit used for uplink transmission. This uplink time unit can be at least one of the following: uplink frame, uplink subframe, uplink timeslot, uplink symbol, special timeslot configured for uplink, flexible symbol configured for uplink, frame corresponding to uplink signal transmission, timeslot corresponding to uplink signal transmission, uplink transmission time unit, or a future-defined uplink time unit. Correspondingly, the aforementioned downlink time unit refers to a time unit used for downlink transmission. This time unit can be at least one of the following: downlink frame, downlink subframe, downlink timeslot, downlink symbol, special timeslot configured for downlink, flexible symbol configured for downlink, frame corresponding to downlink signal transmission, timeslot corresponding to downlink signal transmission, downlink transmission time unit, or a future-defined downlink time unit.

[0010] It should be noted that the first downlink time unit, the first uplink time unit, the second uplink time unit, the second downlink time unit, or the third time unit mentioned above can be time units on the time domain resource line corresponding to the terminal device.

[0011] Optionally, the first time-domain resource is located after the first downlink time unit and before the first uplink time unit in the time domain. This means that the first time-domain resource is located in the time interval between the uplink time slot and the downlink time slot in the optional implementation, which enables the transmission of sensing signals without affecting the normal transmission of communication signals.

[0012] Alternatively, considering that there may not be a first uplink time unit after the first downlink time unit, the first time domain resource is specifically located after the first downlink time unit in the time domain; the above-mentioned absence of a first uplink time unit can be understood as the configuration of a first uplink time unit, but the uplink signal is not transmitted in the first uplink time unit or the first uplink time unit is not configured.

[0013] Alternatively, considering that there may not be a first downlink time unit before the first uplink time unit, the first time domain resource is specifically located before the first uplink time unit in the time domain; the aforementioned absence of a first downlink time unit can be understood as the first downlink time unit being configured, but the downlink signal not being transmitted in the first downlink time unit or the first downlink time unit not being configured.

[0014] In existing technologies, a timing advance mechanism is introduced to overcome propagation delays caused by the distance between network devices and terminal devices, as well as delays caused by transmit / receive switching. This results in uplink and / or downlink transmissions still occurring in a special time slot (the time slot between downlink and uplink time slots). Resources not used for uplink or downlink transmission in this special time slot can be used to transmit sensing signals. This approach does not affect communication performance and makes efficient use of resources.

[0015] Optionally, the second time-domain resource is located after the second uplink time unit and before the second downlink time unit in the time domain. This means that in the optional implementation, the second time-domain resource is in the time interval between the downlink time slot and the uplink time slot, which also enables the transmission of sensing signals without affecting the normal transmission of communication signals.

[0016] Similarly, the timing advance mechanism also leaves some unused resources between the uplink and downlink time slots. These unused resources can also be used to transmit sensing signals. This achieves both the performance of communication and the efficient use of resources.

[0017] Optionally, based on the same considerations as the first uplink time unit mentioned above, there may not be a second downlink time unit after the second uplink time unit. Therefore, the second time domain resource is specifically located after the second uplink time unit in the time domain.

[0018] Optionally, based on the same considerations as the first uplink time unit mentioned above, there may not be a second downlink time unit after the second uplink time unit. Therefore, the second time domain resource is specifically located after the second uplink time unit in the time domain.

[0019] In one possible implementation, the time-domain location of the third time-domain resource belongs to the aforementioned time interval between symbols. The time slot where the third time-domain resource is located can also be used to transmit communication signals, i.e., to transmit uplink data (and / or downlink data). The third time-domain resource used for transmitting sensing signals and the resource used for transmitting communication signals do not overlap in the time domain.

[0020] In one possible implementation, the third time-domain resources utilize the time-domain resources corresponding to one or more cyclic prefixes (CPs) within the third time unit. It is understood that sensing is primarily concerned with short-range transmission. That is, if the distance is short, a long CP is not required. If the CP can be shortened, the remaining time-domain resources can be used to transmit and / or receive sensing signals.

[0021] For example, the third time-domain resource is determined based on the CP in the third time unit, which can be any frame or any time slot. Considering that the third time-domain resource uses the remaining resources after shortening the resources corresponding to the CP within the third time unit, the third time-domain resource can be a resource at any position within the third time unit. The third time unit (time slot) where the third time-domain resource is located can also be used to transmit the CP. Specifically, the third time-domain resource used for transmitting sensing signals and the resource used for transmitting the CP can overlap, partially overlap, or not overlap in the time domain.

[0022] Optionally, the third time-domain resource is located within the third time unit, specifically after the last communication symbol within the third time unit. This means that the third time-domain resource can be located at the end position within the third time unit.

[0023] Optionally, the third time-domain resource is located within the third time unit, specifically before the first communication symbol within the third time unit. This means that the third time-domain resource can be located at the beginning of the third time unit.

[0024] Optionally, considering that there may be a situation in the third time unit where the resources used for transmitting CP are higher than the first threshold, the third time domain resources may be set in the resources used for transmitting CP that are higher than the first threshold, that is, the time domain resources of one or more cyclic prefixes in the third time unit include the third time domain resources.

[0025] In one optional implementation, the first uplink time unit includes at least one of an uplink frame, an uplink timeslot, a frame corresponding to the transmission of an uplink signal, a timeslot corresponding to the transmission of an uplink signal, an uplink transmission time unit, or a future-defined uplink time unit; the first downlink time unit includes at least one of a downlink frame, a downlink timeslot, a frame corresponding to the transmission of a downlink signal, a timeslot corresponding to the transmission of a downlink signal, a downlink transmission time unit, or a future-defined uplink time unit.

[0026] Optionally, the aforementioned uplink frame, uplink time slot, downlink frame, or downlink time slot can be a frame or time slot used for transmitting data, including cases where communication signals are configured but not actually transmitted. The first uplink time unit and the first downlink time unit include the frame / time slot corresponding to the time line on the terminal device side.

[0027] In this embodiment, by clearly defining the first uplink time unit and the first downlink time unit, a clear reference benchmark is provided for the time-domain resource allocation of the sensing signal. This definition not only helps the device accurately identify the time periods available for transmitting the sensing signal, but also ensures the coordination between sensing operations and normal communication activities, avoiding potential interference and conflicts.

[0028] In one alternative implementation, the first time-domain resource is at least M consecutive symbols within a first time slot, where M is a positive integer from 1 to 14.

[0029] Optionally, the first time slot is a time slot used for transmitting sensing signals.

[0030] Optionally, the first time domain resource is at least M consecutive symbols after the first downlink time unit and / or before the first uplink time unit. Specifically, the first time domain resource is at least M consecutive symbols after the first downlink time unit, or, the first time domain resource is at least M consecutive symbols before the first uplink time unit, or, the first time domain resource is at least M consecutive symbols after the first downlink time unit and before the first uplink time unit.

[0031] In this embodiment, the allocation of time-domain resources for the sensing signal is further refined by specifying the first time-domain resource as a symbol. This specific allocation method enables the device to more precisely control the transmission time and duration of the sensing signal, thereby improving the accuracy and efficiency of the sensing operation.

[0032] In one alternative implementation, the first time slot includes part or all of the special time slot.

[0033] In this embodiment, the flexibility of special time slots is fully utilized by allowing the first time domain resources to include part or all of them. This utilization not only expands the range of selectable time periods for sensing signal transmission but also enables the device to flexibly schedule sensing operations within special time slots, further improving the system's resource utilization.

[0034] In one alternative implementation, the first time-domain resource includes any one of the following:

[0035] The M consecutive symbols following the first downlink time unit;

[0036] The first M consecutive symbols following the first downlink time unit;

[0037] The M consecutive symbols preceding the first uplink time unit;

[0038] The last M consecutive symbols before the first uplink time unit.

[0039] It should be noted that the first M consecutive symbols after the first downlink time unit can refer to the M consecutive symbols after the last communication symbol of the first downlink time unit and adjacent to that last communication symbol; the last M consecutive symbols before the first uplink time unit can refer to the M consecutive symbols before the first communication symbol of the first uplink time unit and adjacent to that first communication symbol.

[0040] In one alternative implementation, the first time-domain resource is located in the time domain in any of the following ways:

[0041] The first time-domain resource is located after the first downlink time unit and before the first uplink time unit in the time domain; specifically, the first time-domain resource is located after the first downlink time unit in the time domain; specifically, the first time-domain resource is located before the first uplink time unit in the time domain.

[0042] In one alternative implementation, the first downlink time unit includes a DL time slot or a DL transmission.

[0043] For example, the first time-domain resource is located after the DL timeslot in the time domain, or the first time-domain resource is located after the DL transmission in the time domain.

[0044] In one alternative implementation, the first uplink time unit includes a UL time slot or a UL transmission.

[0045] For example, the first time-domain resource is located before the UL timeslot in the time domain, or the first time-domain resource is located before the UL transmission in the time domain.

[0046] In one optional implementation, the time interval between the first time domain resource and the first downlink time unit is greater than or equal to a first time, and / or the time interval between the first time domain resource and the first uplink time unit is greater than or equal to the first time, and / or the time interval between the first time domain resource and the first downlink time unit is greater than or equal to a second time, and / or the time interval between the first time domain resource and the first uplink time unit is greater than or equal to the second time; the first time is located before and / or after the first time domain resource in the time domain, and the second time is located before and / or after the first time domain resource in the time domain.

[0047] In one optional implementation, the first time is the time of transmit / receive conversion or a predefined time, and the second time is the time of transmit / receive conversion or a predefined time.

[0048] In this embodiment, by defining the time interval between the first time domain resource and the first uplink / downlink time unit, effective isolation between the sensing signal transmission period and the normal communication period is ensured, reserving a certain amount of resource space for the transmission and reception of communication signals. This isolation not only avoids interference between sensing operations and normal communication but also ensures the continuity and stability of communication activities. Furthermore, by introducing the first and second times, the device is provided with more flexible time interval selection, further enhancing the flexibility of resource allocation.

[0049] In one optional implementation, the first duration of the first time-domain resource and the second duration of the timing advance satisfy the following relationship:

[0050] T1≥T sensing +T TA Or, T1≥T sensing+T TA +N TA,offset ·T c

[0051] Where T1 represents the duration of A special time slots or A first time slots, A is a positive integer greater than or equal to 1, and T... sensing T represents the first duration of the resource in the first time domain. TA N is the second duration of the timed advance. TA,offset ·T c For the first and / or second time.

[0052] In this embodiment, by defining the relationship between the first duration of the first time-domain resource and the second duration of the timing advance, the coordination between the sensing signal transmission period and the timing advance is further ensured. The timing advance N can be determined based on the duration of the first time-domain resource. TA The value, or, can be based on a timed advance of N. TA The value of determines the duration of the first time-domain resource. Due to the timing advance T... TA The value corresponds to the maximum communication distance between the first device and the third device. The maximum communication distance between the first device and the third device can be determined based on the duration of the first time-domain resource (first duration), or it can be determined based on a time advance T. TA The value determines the duration of the first time domain resource (first duration). This coordination not only helps the device accurately calculate the transmission time of the sensed signal, but also avoids signal transmission failure or misjudgment caused by inaccurate timing.

[0053] Optionally, the first time can indicate the time of transmission / reception conversion / predefined time, or it can indicate the specific time length; the second time is similar.

[0057] In this embodiment, within A special time slots or A first time slots, the timing is advanced by N. TA The longer the duration T of the first time domain resource, the more... sensing The shorter the length. Furthermore, in this embodiment, transmit / receive switching can be performed before and / or after transmitting the sensing signal, which also requires 2N... TA,offset The reason.

[0059] T1≥T sensing +(N TA +N TA,offset1 +N TA,offset2 )T c Or, T1≥T sensing +T TA +N TA,offset2 ·T c

[0060] Where T1 represents the duration of A special time slots or A first time slots, A is a positive integer greater than or equal to 1, and T... sensing N represents the duration of the first time-domain resource. TA Indicator timing advance (N) TA ·T c (The fourth time interval before the scheduled start time), N TA,offset1 Instructions at the first time (N) TA,offset1 ·T c (The duration of the first moment), N TA,offset2 Indicates the second time (N) TA,offset2 ·T c (The duration of the second time period).

[0061] In this embodiment, transmit-receive switching is performed before transmitting the sensing signal, and transmit-receive switching is performed after transmitting the sensing signal; or transmit-receive switching is performed before transmitting the sensing signal, and transmit-receive switching is performed after transmitting the sensing signal. This also requires N TA,offset1 With N TA,offset2 The reason.

[0062] In one alternative implementation, there is at least one flexible symbol preceding the first time domain resource, or there is at least one flexible symbol between the first time domain resource and the first uplink symbol, or there is at least one flexible symbol between the first time domain resource and the first downlink symbol.

[0063] In this embodiment, at least one flexible symbol is introduced before, after, or adjacent to the first time-domain resource. This flexible symbol can be used for transmit / receive switching. The introduction of this flexible symbol not only enhances the device's ability to switch between different operating modes but also improves the flexibility and reliability of sensing signal transmission.

[0116] In this embodiment, by allowing the periods of the first and second time-domain resources to be integer multiples of the uplink / downlink matching period, a more flexible resource configuration method is provided for the device. This periodic configuration does not limit the configuration of the first time-domain resource within the uplink / downlink matching period; for example, this period can be decoupled from the period of the time-slot mode. Taking the time-slot mode as DDDSU as an example, the period of the time-slot mode is 5 time slots. The first time-domain resource can be indicated / configured / enabled in a specific time slot within the first DDDSU, and it can be neither indicated / configured / enabled in a specific time slot within the second DDDSU. This not only helps the device to distribute sensing operations more evenly over time but also improves the system's resource utilization and sensing efficiency.

[0117] In one alternative implementation, the sensing signal is used to determine information about the sensing target.

[0118] The process of determining the information of the sensing target can also be referred to as operating a sensing service, or simply as performing sensing. This sensing signal is used to determine the information of the sensing target. A first device sends a sensing signal. After receiving the sensing signal, a second device can determine the information of the sensing target based on the sensing signal. In other words, the first device sends the sensing signal so that the second device can receive it; therefore, it can also be described as: the sensing signal sent by the first device is used to determine the information of the sensing target.

[0119] In one optional implementation, acquiring at least one of the first time-domain resources, the second time-domain resources, or the third time-domain resources includes the following operations:

[0120] The first device acquires a sensing resource configuration message, which indicates at least one of the first time domain resources, the second time domain resources, or the third time domain resources.

[0121] In this embodiment, at least one of the first, second, or third time-domain resources is obtained by receiving a sensing resource configuration message, providing the device with a clear resource allocation instruction. This message acquisition method not only simplifies the resource configuration process but also improves the accuracy and reliability of resource configuration.

[0122] Optionally, the sensing resource configuration message can be configured by a first device. For example, if the first device is a terminal device, then the sensing resource configuration message is configured by the terminal device; if the first device is a network device, then the sensing resource configuration message is configured by the network device; the sensing resource configuration message can also be configured by a second device; the sensing resource configuration message can also be configured by a third device, which can be another terminal device or another network device. It should be understood that "other terminal devices" here refers to devices different from the aforementioned terminal device (first device), and "other network devices" here refers to devices different from the aforementioned network device (first device).

[0123] In one optional implementation, obtaining the perception resource configuration message includes the following operations:

[0124] The first device receives the sensing resource configuration message.

[0125] Optionally, the perception resource configuration message may be sent by a third party, such as a third device. The third device may be a terminal device or a network device. If the first device is a terminal device, the third party may refer to other terminal devices.

[0126] In an optional implementation, the above method may further include the following operations:

[0127] The first device sends a first request message, which is used to request the configuration of at least one of the first time domain resources, the second time domain resources, or the third time domain resources.

[0128] In one alternative implementation, the perceived resource configuration message includes a first index, which is a time-slot format index indicating a first time-domain resource, wherein the first index belongs to at least one of time-slot formats 56 to 254.

[0129] In this embodiment, by using an index in the time slot format to indicate the first time domain resource, a more intuitive and concise resource representation method is provided for the device. Furthermore, this embodiment defines a new time slot format that supports the transmission of sensing signals within a time slot. This index representation method not only simplifies the resource identification process but also improves the convenience of resource allocation and use.

[0130] In one alternative implementation, the perceived resource configuration message is used to indicate that at least one of a first downlink symbol, a first uplink symbol, or a flexible symbol within a specific time slot is a first time-domain resource.

[0131] It should be noted that the aforementioned sensing resource configuration message specifically indicates the use of at least one format from 0 to 55 in the time slot format. It can be understood that the aforementioned sensing resource configuration message is equivalent to reusing an existing time slot format. This is achieved by updating at least one of the first downlink symbol, the first uplink symbol, or the flexible symbol with the symbol used for transmitting sensing data.

[0132] In one alternative implementation, the perceived resource configuration message indicates a second uplink time unit;

[0133] Transmitting a sensing signal on at least one of the first, second, or third time domain resources includes the following operation: the first device transmits the sensing signal on a second time domain resource after the second uplink time unit.

[0134] In an optional implementation, the sensing resource configuration message is further used to indicate whether to send a sensing signal after the second uplink time unit. The sensing resource configuration message includes a first value or a second value, wherein the first value indicates that no sensing signal is sent after the second uplink time unit, and the second value indicates that a sensing signal is sent after the second uplink time unit.

[0135] Optionally, the first value mentioned above can also be used to indicate the transmission of communication signals in the second uplink time unit.

[0136] It should be noted that the second time-domain resource does not belong to any single time slot; it exists as a time unit / time-domain resource that follows the uplink time slot and precedes the downlink time slot. Therefore, by indicating the second uplink time unit, the second time-domain resource can be indicated, or the transmission of sensing signals on the second time-domain resource can be indicated.

[0137] Optionally, the second uplink time unit can transmit communication signals.

[0138] In one possible implementation, if the sensing resource configuration message only indicates the second uplink time unit, it is impossible to distinguish between the transmission of communication signals in the second uplink time unit and the transmission of sensing signals on the second time domain resource. Therefore, a second value is introduced to distinguish between these two cases, expressing the indication requirement in the form of a value, thus reducing information transmission overhead.

[0139] In one alternative implementation, the perceived resource configuration message indicates a second downlink time unit;

[0140] Transmitting a sensing signal on at least one of the first, second, or third time domain resources includes the following operation: the first device transmits a sensing signal on a second time domain resource prior to the second downlink time unit.

[0141] In an optional implementation, the sensing resource configuration message is further used to indicate whether to send a sensing signal before the second downlink time unit. The sensing resource configuration message includes a third value or a fourth value, wherein the third value is used to indicate that the sensing signal is not sent before the second downlink time unit, and the second value is used to indicate that the sensing signal is sent before the second downlink time unit.

[0142] Optionally, the third value mentioned above can also be used to indicate the transmission of communication signals in the second downlink time unit.

[0143] It should be understood that the second time-domain resource does not belong to any single time slot; rather, it exists as a time unit / time-domain resource between the downlink time slot and the downlink time slot. Therefore, by indicating the second downlink time unit, the indication of the second time-domain resource is achieved, or the indication of transmitting sensing signals on the second time-domain resource is achieved.

[0144] The second downlink time unit can transmit communication signals. If only the second downlink time unit is indicated, it is impossible to distinguish between transmitting communication signals in the second downlink time unit and transmitting sensing signals on the second time domain resource. Therefore, a fourth value is introduced to distinguish between these two cases.

[0145] In this embodiment of the application, the sensing signal is sent on time domain resources after the second uplink time unit or the second downlink time unit by instructing the sensing resource configuration message, which provides the device with more flexible resource selection.

[0146] In one optional implementation, the sensing resource configuration message indicates a third time-domain resource, or indicates the time slot or subframe where the third time-domain resource is located; transmitting a sensing signal on at least one of the first, second, or third time-domain resources includes the following operations: the first device transmits a sensing signal on the third time-domain resource, or the first device transmits a sensing signal on the time slot or subframe where the third time-domain resource is located.

[0147] In an optional implementation, the sensing resource configuration message is further used to indicate whether a sensing signal is transmitted in the third time domain resource or the time slot or subframe where the third time domain resource is located. The sensing resource configuration message includes a fifth value or a sixth value. The fifth value is used to indicate that a sensing signal is not transmitted in the third time domain resource or the time slot or subframe where the third time domain resource is located, and the sixth value is used to indicate that a sensing signal is transmitted in the third time domain resource or the time slot or subframe where the third time domain resource is located.

[0148] Optionally, the fifth value mentioned above can also be used to indicate the transmission of communication signals in the third time domain resource or the time slot or subframe where the third time domain resource is located.

[0149] In this embodiment, the third time-domain resource belongs to the third time unit. The third time unit can transmit communication signals. If only the third time unit is indicated, it is impossible to distinguish between the case of transmitting communication signals in the third time unit and the case of transmitting communication signals and sensing signals on the second time-domain resource. Therefore, a fifth value is introduced to distinguish between these two cases.

[0150] In one alternative implementation, the perceived resource configuration message is carried by a control message, which includes at least one of a Radio Resource Control Message (RRC), a Medium Access Control Element (MAC CE), or Downlink Control Information (DCI).

[0151] In this embodiment, the perceived resource configuration message is carried by control messages (such as RRC, MAC CE, or DCI), providing a reliable resource configuration method for the device. This method not only ensures the accuracy and timeliness of resource configuration information but also improves the communication efficiency and stability of the system.

[0152] In one alternative implementation, a fourth device that meets at least one of the following conditions uses the same time-domain resource configuration as the first device, including: the same timing advance group (TAG); the same cell; the same bandwidth; the same frequency band; the same network; or any network.

[0153] In this embodiment, by specifying that a fourth device meeting certain conditions uses the same time-domain resource configuration as the first device, resource coordination and consistency among multiple devices in the system are ensured. This configuration method not only avoids resource conflicts and interference between devices but also improves the overall system performance and user satisfaction.

[0154] In one alternative implementation, the energy of the sensing signal transmitted from the first time-domain resource is greater than or equal to a first energy threshold, and / or the energy of the sensing signal transmitted from the second time-domain resource is less than or equal to a second energy threshold.

[0155] By specifying energy thresholds for transmitting sensing signals on both the first and second time-domain resources, clear energy control requirements are provided for the device. This energy control method not only helps protect the device's transmit power and battery life but also improves the reception quality of sensing signals and the overall performance of the system.

[0156] In one optional implementation, a first device transmits a sensing signal on a second time-domain resource. The first device is a terminal device. Since the energy of the sensing signal transmitted by the terminal device on the second time-domain resource is low (less than or equal to a second energy threshold), different terminal devices can share the second time-domain resource to transmit sensing signals. For example, different terminal devices can transmit sensing signals on different frequency domain resources of the second time-domain resource respectively, and multiple terminal devices do not affect each other.

[0157] In one optional implementation, the first device is a network device, which transmits a sensing signal on at least one of the first, second, or third time domain resources, including the following operations:

[0158] The network device transmits a sensing signal on a first time domain resource, and / or the network device transmits a sensing signal on a second time domain resource.

[0159] In one optional implementation, the first device is a terminal device, which transmits a sensing signal on at least one of the first, second, or third time domain resources, including the following operations:

[0160] The terminal device transmits sensing signals in the second time domain resources, and / or the terminal device transmits sensing signals in the first time domain resources.

[0161] In one optional implementation, the first time-domain resource is used for network devices to transmit sensing signals, and the second time-domain resource is used for terminal devices to transmit sensing signals. It should be understood that in this implementation, the first time-domain resource is used for transmission based on downlink sensing signals, and the second time-domain resource is used for transmission based on uplink sensing signals.

[0162] Secondly, a resource allocation method is provided, which is executed by a second device. The second device can be a device capable of receiving sensing signals. For example, the second device is a terminal device or a component within a terminal device, such as a chip. As another example, the second device is a network device or a component within a network device, such as a chip. This application does not impose any limitations on this. The following description uses a network device as an example to illustrate the above resource allocation method, where the second device can perform the following operations:

[0163] The second device acquires at least one of the following time-domain resources: a first time-domain resource, a second time-domain resource, or a third time-domain resource; wherein the first time-domain resource is located after the first uplink time unit and before the first downlink time unit in the time domain, the second time-domain resource is located after the second uplink time unit and before the second downlink time unit in the time domain, and the third time-domain resource is located after the last communication symbol in the third time unit, or before the first communication symbol in the third time unit, or the time-domain resources of one or more cyclic prefixes in the third time unit include the third time-domain resource;

[0164] The second device receives a sensing signal on at least one of the first, second, or third time domain resources.

[0165] This application provides a resource allocation method executed by a second device, which allows the second device (such as a network device) to receive sensing signals on specific time-domain resources. Considering that current communication technologies do not allocate dedicated resources for sensing signals, the method provided in this application enables sensing signals to be transmitted on time-frequency resources not currently used for transmitting uplink or downlink information in existing protocols. For example, the time interval between uplink and downlink time slots, the time interval between downlink and uplink time slots, and the time interval between symbols are all potential resources that can be used to transmit sensing signals. This flexible resource allocation method allows the device to effectively utilize time-domain resources for sensing operations without affecting normal communication, thereby improving the system's resource utilization and sensing efficiency. Since no communication signals are transmitted on the aforementioned time intervals, transmitting sensing signals in these intervals does not affect communication performance and makes reasonable use of resources.

[0166] The remaining beneficial effects and potential outcomes can be found in the relevant description in the first aspect, and will not be repeated here.

[0674] The following explanations, in conjunction with the embodiments of this application, will clarify some terms or concepts used in the embodiments of this application, so that those skilled in the art can understand them.

[0675] 1. Wireless frame structure.

[0676] In mobile communication, data is transmitted on wireless networks in units of frames, meaning that a frame is the time unit for data transmission. Frames typically occupy a very short time; for example, an LTE radio frame is 10ms, and a subframe is 1ms. This allows for the allocation of different subframes to transmit data to multiple users within one second. Because subframe switching is very fast, users perceive real-time transmission; for example, the LTE transmission time interval (TTI) can be 1ms. Similar to LTE, 5G radio frames and subframes have fixed lengths, allowing for better coexistence between LTE and NR. However, 5G NR defines a flexible sub-architecture, where time slots and character lengths can be flexibly defined based on the subcarrier spacing (SCS).

[0677] Furthermore, the TDD frame structure is introduced:

[0678] The frame format of a 5G (5th generation) NR system in TDD duplex mode includes downlink slots, special slots, and uplink slots. Special slots include at least one of uplink symbols, downlink symbols, and flexible symbols. Special slots generally follow downlink slots and precede uplink slots. Special slots can also be referred to as S-slots.

[0679] The number of uplink time slots can be one or more, the number of downlink time slots can be one or more, and the number of special time slots is one.

[0680] In a 5G NR system, the frame length of a radio frame is 10 milliseconds (ms). This radio frame comprises 10 subframes, each with a frame length of 1 ms. The number of time slots included in each subframe is determined by the system parameter set (numerologies). The time slots used for uplink transmission and downlink transmission in each radio frame are determined by the uplink-downlink pattern (DL-UL pattern, or TDD DL-UL pattern). The uplink-downlink pattern can also be referred to as the TDD frame pattern, TDD uplink-downlink frame pattern, etc.

[0681] The uplink / downlink ratio period is the number of time slots included in the uplink / downlink ratio (e.g., in time slots), or the duration of the time slots included in the uplink / downlink ratio (e.g., in milliseconds).

[0682] For example, taking an uplink / downlink ratio of 4:1, with each subframe comprising one time slot as an example. The uplink / downlink ratio period is 5 time slots. Under this structure, the types of time slots in the radio frame can be as shown in Table 1.

[0683] Table 1

[0684] In Table 1 above, time slot D corresponds to a downlink time slot, time slot U corresponds to an uplink time slot, and time slot S corresponds to a special time slot. The ratio of time slot D, time slot U, and time slot S in the following embodiments can be found in Table 1, and will not be repeated here.

[0685] With an uplink-to-downlink ratio of 4:1, the uplink-to-downlink ratio period can include 5 time slots, such as time slots 0-4 in Table 1, or time slots 5-9. These 5 time slots include 3 downlink time slots, 1 special time slot, and 1 uplink time slot. The special time slot is located between the downlink and uplink time slots, serving as the transition point between uplink and downlink.

[0686] Taking an uplink-to-downlink ratio of 8:2 and each subframe as an example, the types of time slots in a radio frame under this structure can be shown in Table 2.

[0687] Table 2

[0688] With an uplink / downlink ratio of 8:2, the uplink / downlink ratio cycle comprises 10 time slots, such as time slots 0-9 in Table 2. These 10 time slots include 7 downlink time slots, 1 special time slot, and 2 uplink time slots. The special time slot is located between the downlink and uplink time slots and can be used for uplink / downlink switching.

[0689] 2. Time slot format.

[0690] A special time slot includes at least one of the following: uplink symbols, downlink symbols, and flexible symbols. The number and position of uplink symbols, downlink symbols, and flexible symbols within a special time slot are called the time slot format.

[0691] Additionally, control information sent by network devices can indicate whether flexible symbols are used for uplink or downlink transmission. A flexible symbol indicated as downlink can be considered a downlink symbol, and similarly, a flexible symbol indicated as uplink can be considered an uplink symbol.

[0692] Time slot format refers to the allocation and usage of time slots in different communication systems. In mobile communication systems, time slot format defines the allocation of time and frequency domain resources to ensure efficient and reliable communication between mobile stations and base stations.

[0693] The 3rd Generation Partnership Project (3GPP) protocols currently provide clear definitions for time slot formats. For example, the time slot format involved in this application embodiment can be referenced to Table 11.1.1-1 in technical specification (TS) 38.213, which is named the time slot format for cyclic prefix (CP).

[0694] The time slot format currently includes 56 defined time slot formats corresponding to format values ​​from 0 to 55, while 199 time slot formats corresponding to format values ​​from 56 to 254 are reserved and have not yet been defined. Examples of the above-mentioned ordinary cyclic prefix time slot formats are given in Table 3.

[0695] Table 3

[0696] In Table 3 above, symbol D corresponds to the downlink symbol, symbol U corresponds to the uplink symbol, and symbol F corresponds to the flexible symbol. The symbols D, U, and F appearing in the following embodiments, or the uplink / downlink ratio of the downlink, uplink, and flexible symbols, can be found in Table 3 in some implementations. Any special cases will be specifically explained later.

[0697] For example, a special timeslot may contain 14 symbols, taking timeslot format 4 and timeslot format 32 as examples. Timeslot format 4 includes 12 downlink symbols and two flexible symbols, but no uplink symbols. Timeslot format 32 includes 10 downlink symbols, 2 flexible symbols, and 2 uplink symbols.

[0698] 3. Sensing signals.

[0699] A sensing signal can also be called a signal applied to sensing, a sensing reference signal, or a reference signal used for sensing. A sensing signal can be transmitted independently, or it can be transmitted along with a communication signal, or it can be a communication signal used for sensing services.

[0700] In this embodiment, the sensing signal can be channel state information, such as any one of the following: channel state information-reference signal (CSI-RS), synchronization signal block (SSB), positioning reference signal (PRS), sounding reference signal (SRS), sensing reference signal, and demodulation reference signal (DMRS). The SRS can be a multi-input multi-output (MIMO) SRS or a positioning SRS.

[0701] The sensing signal can propagate via a path of "sensing transmitter - sensing target - sensing receiver", or via a path of "sensing transmitter - sensing receiver", or via a path of "sensing transmitter - interference / environment - sensing receiver". In other words, the sensing signal can be a single path or a combination of these paths, and the sensing receiver receives the sum of the signals from the aforementioned paths. In this embodiment, the sensing signal transmitted by the sensing transmitter and the sensing signal received by the sensing receiver are the same signal (e.g., both referred to as the sensing signal). During sensing, changes in the received sensing signal compared to the transmitted sensing signal include changes caused by reflection or scattering from the sensing target, such as changes in the time and / or frequency domains of the sensing signal, and changes in the amplitude and / or phase of the sensing signal. These changes reflect information about the sensing target (e.g., the speed, distance, and direction of the sensing target). In other words, the information of the sensing target can be determined based on the received sensing signal.

[0702] 4. Time-domain resource unit and frequency-domain resource unit.

[0703] Resources carry signals, or signals are mapped onto resources. Resources include two dimensions: the time domain and / or the frequency domain. The unit of a time-domain resource is a time-domain unit, and the unit of a frequency-domain resource is a frequency-domain unit.

[0704] The time-domain units involved in the embodiments of this application include symbols, orthogonal frequency division multiplexing (OFDM) symbols, slots, sensing slots, mini-slots, partial slots, sub-frames, frames, and radioframes.

[0705] Frequency domain units include resource elements (REs), resource blocks (RBs), RB sets, subchannels, control channel elements (CCEs), resource pools, bandwidth parts (BWPs), carriers, channels, interlaces, combs, etc.

[0706] The time-domain and frequency-domain units described above can be combined arbitrarily. For example, a resource can be a time-frequency resource with symbols in the time domain and resource particles in the frequency domain. Another example is a time-frequency resource with symbols in the time domain and resource blocks in the frequency domain.

[0707] In the embodiments of this application, the main focus is on time-domain resources. The time-domain unit for transmitting sensing signals can also be called the transmission occasion of sensing signals; the two can be used interchangeably.

[0708] 5. Time unit.

[0709] A time unit generally refers to a unit of time. For example, a time unit can be, but is not limited to, a radio frame, a subframe, a slot, or a symbol. The symbol can be a time-domain symbol (e.g., an orthogonal frequency division multiplexing (OFDM) symbol). For example, a time unit can be a time-domain resource, or a time-domain resource can specifically be a time unit, or a time unit can be a non-time-domain resource. A time unit and a time-domain resource can have an inclusion relationship. For example, a time-domain resource may contain one or more time units. A time unit and a time-domain resource may also not have an inclusion relationship.

[0710] If a time unit is prefixed with "uplink" or "downlink," it indicates that the time unit has been used as a time-domain resource for transmitting uplink or downlink signals. In this embodiment, the time unit can be either an uplink time unit or a downlink time unit.

[0711] Uplink time units can have different granularities, such as an uplink time unit 1 and an uplink time unit 2. Exemplarily, in the embodiments of this application, the uplink time unit 1 is an uplink symbol, and the uplink time unit 2 is an uplink timeslot. For example, the uplink time unit 2 includes at least one uplink time unit 1. Unless otherwise specified, this application uses the term "uplink time unit" to refer generally to the uplink time unit 1 and / or the uplink time unit 2.

[0712] Downlink time units can have different granularities, such as a first downlink time unit and a second downlink time unit. Exemplarily, in this application embodiment, the first downlink time unit is a downlink symbol, and the second downlink time unit is a downlink time slot. For example, the second downlink time unit includes at least one first downlink time unit. Unless otherwise specified, this application uses the term "downlink time unit" to refer generally to the first downlink time unit and / or the second downlink time unit.

[0713] In this context, the first uplink time unit and the first downlink time unit refer to the granularity of uplink time, not a specific symbol. Similarly, the second uplink time unit and the second downlink time unit refer to the granularity of uplink time, not a specific time slot. In addition, this application embodiment also involves a first uplink time unit, a second uplink time unit, etc., specifically referring to a particular time / time domain resource.

[0714] As exemplarily illustrated, in this embodiment of the application, the uplink time unit is used for uplink transmission. For example, the uplink time unit may be an uplink radio frame, an uplink frame, an uplink time slot, or an uplink symbol. In this embodiment, the uplink time unit can refer to a time unit in which uplink signals are transmitted (including radio frames, frames, time slots, or symbols), or it can refer to a time unit used for transmitting uplink signals (including cases where signals are configured but not transmitted). For example, the first uplink time unit may be an uplink time slot. Specific uplink time slots can be found in Table 1 or Table 2, specifically in the time slot U.

[0715] Downlink time units are used for downlink transmission. For example, a downlink time unit can be a downlink radio frame, a downlink frame, a downlink time slot, or a downlink symbol. In the embodiments of this application, a downlink time unit can refer to a time unit in which downlink signals are transmitted (including radio frames, frames, time slots, or symbols), or it can refer to a time unit used for transmitting downlink signals (including cases where signals are configured but not transmitted). For example, the first downlink time unit can be a downlink time slot. Specific downlink time slots can be found in time slot D in Table 1 or Table 2.

[0716] Generally, a special time slot is included after the downlink time slot and before the uplink time slot. In the embodiments of this application, the special time slot includes at least one of uplink symbols, downlink symbols, flexible symbols, and sensing symbols. It should be understood that when a special time slot includes a sensing symbol, the sensing symbol is used to transmit sensing signals. Furthermore, if a special time slot includes a sensing symbol, it may also include a flexible symbol, which can be used for both uplink and downlink transmission, but not simultaneously. In the embodiments of this application, the flexible symbol can also be used for sensing transmission.

[0717] Optionally, the time slot containing the sensing symbol can be called the sensing time slot. Therefore, in cases where a special time slot includes a sensing symbol, the special time slot can also be called the sensing time slot.

[0718] Optionally, when a special time slot includes a sensing symbol, it may also include at least one of an uplink symbol, a downlink symbol, and a flexible symbol. For example, a special time slot may include a sensing symbol and a flexible symbol.

[0719] It is understood that the time domain positions of the uplink and / or downlink time units can be (pre-)configured by the network device to the terminal device, or they can be predefined. In this embodiment, the network device configures or instructs the terminal device by sending signaling to the terminal device, which may carry the information to be configured, such as the configuration information of the time domain positions of the uplink and / or downlink time units. Optionally, higher-layer signaling may be, for example, radio resource control (RRC) layer signaling, media access control (MAC) layer signaling, or downlink control information (DCI). Furthermore, in this application, the predefined method can be configured before the device leaves the factory, or it can be defined through the communication protocol.

[0720] 6. Timing advance (TA).

[0721] Because different terminal devices are located at different distances from network devices, uplink information sent by different terminal devices will arrive at the network device at different times, causing signal interference. Therefore, terminal devices need to maintain timed synchronization with network devices. After downlink synchronization is completed, the terminal device can accurately receive downlink signals sent by the network device; after uplink synchronization is completed, the network device can accurately receive uplink signals sent by the terminal device. Uplink synchronization is mainly achieved by the terminal device using a specific TA (Transmission Time Acquisition) to adjust the uplink transmission time. In other words, there is a time interval between uplink (time slot) and downlink (time slot) to satisfy propagation delay and uplink / downlink switching.

[0722] The timing of a terminal device transmitting uplink signals (or transmission timing) is preceded by a certain amount of time relative to the timing of the terminal device receiving downlink signals; this is called uplink timing advance. This advance typically includes two parameters: timing advance (TA) and timing advance offset (TA-offset). The timing advance is dynamically configured by the network device for each terminal device; the base station configures different TA values ​​for each terminal device depending on the distance between the terminal device and the network device. The TA-offset is usually a statically configured parameter of the network device and does not change with the distance between the terminal device and the network device.

[0723] Please see Figure 1 for details. Figure 1 is a schematic diagram of a timing advance in the prior art.

[0724] T in Figure 1 TA Used to refer to the duration of a scheduled advance.

[0725] Among them, T c =1 / (Δf) max ·N f ), Δfmax=480·10 3 Hz, N f =4096. In the embodiments of this application, T TA This is recorded as the second duration, N. TA T c This is recorded as the fourth duration.

[0726] Timing advance in satellite communication Indicates the timing advance caused by the distance between the reference station and the satellite. This indicates the timing advance caused by the distance between the satellite and the terminal device (first device).

[0727] In non-satellite communication scenarios This will not be elaborated further here.

[0728] There are two types of time intervals caused by advance timing.

[0729] Type 1: Timing advance N caused by propagation delay between network devices and terminal devices TA Please refer to Figure 2, which is a time-domain resource diagram of a network device-side timeline and a terminal device timeline provided in an embodiment of this application. On the terminal device-side timeline, there is a certain time interval N between the uplink and downlink time slots. TA No transmission. Typically in T... A The value (T) A =0, 1, 2, ..., 3846) indicates the time interval N. TA Among them, N TA =T A ·16·64 / 2 μ As shown in Figure 2, there is an N-type time slot between the uplink time slot U and the downlink time slot D. TA The time interval, i.e., the unused portion corresponding to the timeline on the terminal device side in Figure 2. In this embodiment of the application, this portion can be used as a time-domain resource for transmitting sensing signals.

[0730] Type 2: Timing advance N caused by the transmit / receive switching of terminal equipment TA,offset The terminal device needs to perform a transmit / receive conversion to switch from downlink reception to uplink transmission, which takes time N. TA,offset The commonly used values ​​are 25600, 39936, or 13792. In the embodiments of this application, the transmit / receive conversion time can also be referred to as the first time. The transmit / receive conversion time is shown in Table 4, which mainly illustrates the transmit / receive conversion time, or the first time. It is generally considered that the transmit / receive conversion time of FR1 is 13.02us, and the transmit / receive conversion time of FR2 is 7.01us. FR1 refers to the frequency band below 6GHz, while FR2 refers to millimeter wave (mmWave).

[0731] Table 4

[0732] For example, the uplink timing advance of the terminal device sending the demodulation reference signal (DMRS), sounding reference signal (SRS), and physical uplink shared channel (PUSCH) to the network device is the sum of TA and TA-Offset, while the uplink timing advance of the terminal device sending the physical random access channel (PRACH) to the network device is TA-Offset.

[0733] 7. Cyclic Prefix (CP).

[0734] A cyclic prefix (CP) is a technique used in communication systems. A cyclic prefix is ​​a data segment formed by copying the end of an OFDM symbol and adding it to the beginning of the symbol. In wireless communication, signals reach the receiver via different paths, causing multipath fading. The presence of a cyclic prefix ensures that multipath delay spread within a certain range does not disrupt the orthogonality between subcarriers. The propagation distances corresponding to CPs are shown in Table 5. That is, if the multipath propagation distance is less than the distance corresponding to the CP (CP*c in Table 5), the effects of multipath fading can be eliminated using CPs.

[0735] Table 5

[0736] 8. Send-receive conversion or send-receive conversion.

[0737] Transceiver switching refers to a device switching from a receiving state to a transmitting state; transmit-receive switching refers to a device switching from a transmitting state to a receiving state.

[0738] Symbols used for transmitting or receiving, or for transmitting-receiving conversion, can be called empty symbols (GAP symbols) or guard interval (GP) symbols. Communication devices typically neither transmit nor receive on empty symbols.

[0739] The timing of the send / receive conversion can be found in Table 4 and its related content, which will not be repeated here.

[0740] Regarding transmit / receive conversion, the protocol does not explicitly specify the conversion time, but the transmit / receive conversion time N can be used as a reference. TA,offset ·T c (7.01us, 13.02us or 20.31us).

[0741] 9. Frame start time and transmission start time.

[0742] Uplink frames are T frames ahead of downlink frames TA ,in T TA N in TA,offset T c This corresponds to the transmit / receive conversion time. It can be understood that the first N frames of the uplink frame... TA,offset T c Used for transmit / receive conversion. That is, the uplink transmission start time is N times after the uplink frame start time. TA,offset T c Alternatively, the uplink transmission start time is N times after the uplink timeslot start time. TA,offset T cThe uplink transmission start time is N after the uplink symbol start time. TA,offset T c .

[0743] Since the protocol does not explicitly specify the time for the transmit-receive transition, it can be assumed that the start time of downlink transmission is the same as the start time of the downlink frame, or that the start time of downlink transmission is N times after the start time of the downlink frame. TA,offset T c The downlink frame can also be replaced by a downlink time slot or a downlink symbol.

[0744] In the embodiments of this application, "instruction" can include direct and indirect instructions, as well as explicit and implicit instructions. The information indicated by a certain piece of information is called the information to be instructed. In the specific implementation process, there are many ways to instruct the information to be instructed, such as, but not limited to, directly instructing the information to be instructed, such as the information to be instructed itself or its index. It can also indirectly instruct the information to be instructed by instructing other information, where there is a relationship between the other information and the information to be instructed. It can also instruct only a part of the information to be instructed, while the other parts are known or pre-agreed upon. For example, the instruction of specific information can be achieved by using a pre-agreed (e.g., protocol-defined) arrangement of various pieces of information, thereby reducing instruction overhead to some extent. At the same time, common parts of various pieces of information can be identified and uniformly indicated to reduce the instruction overhead caused by individually indicating the same information.

[0745] Furthermore, the specific indication method can also be any existing indication method, such as, but not limited to, the above-mentioned indication methods and their various combinations. Specific details of various indication methods can be found in existing technologies, and will not be repeated here. As described above, for example, when multiple pieces of information of the same type need to be indicated, the indication methods for different pieces of information may differ. In the specific implementation process, the required indication method can be selected according to specific needs. This application embodiment does not limit the selected indication method; therefore, the indication methods involved in this application embodiment should be understood to cover various methods that enable the party to be indicated to obtain the information to be indicated.

[0746] It should be understood that the information to be indicated can be sent as a whole or divided into multiple sub-information messages sent separately, and the sending period and / or timing of these sub-information messages can be the same or different. The specific sending method is not limited in this application embodiment. The sending period and / or timing of these sub-information messages can be predefined, for example, according to a protocol, or configured by the sending device by sending configuration information to the receiving device.

[0747] In this application, "sending information" can be understood as one device sending information to another device, or it can also be understood as one logical module within a device sending information to another logical module. For example, "network device sending information" can be understood as a network device sending information to another device (such as a terminal or other network device), or it can be understood as logical module 1 in the network device sending information to logical module 2 in the network device.

[0748] In this application, "receiving information" can be understood as one device receiving information from another device, or it can also be understood as a logical module within a device receiving information from another logical module. For example, "network device receiving information" can be understood as a network device receiving information from another device (such as a terminal or other network device), or it can be understood as logical module 1 in the network device receiving information from logical module 2 in the network device.

[0749] In this application, phrases such as "sending information to... (e.g., a terminal)" or related illustrations in the accompanying drawings can be understood as indicating that the destination of the information is a terminal. This can include sending information directly or indirectly to a terminal. Similarly, phrases such as "receiving information from... (e.g., a terminal)," "receiving information from... (e.g., a terminal)," or "receiving information sent by (e.g., a terminal)," or related illustrations in the accompanying drawings, can be understood as indicating that the source of the information is a terminal. This can include receiving information directly or indirectly from a terminal. Information may undergo necessary processing between the source and destination, such as format changes, but the destination can understand the valid information from the source. Similar expressions in this application can be interpreted similarly and will not be elaborated further here.

[0750] "Predefined" or "pre-configured" can be achieved by pre-saving corresponding codes, tables, or other means that can be used to indicate relevant information in the device. This application does not limit the specific implementation method. "Saving" can refer to saving in one or more memories. These memories can be separate installations or integrated into the encoder, decoder, processor, or communication device. Alternatively, some memories can be separately installed, while others are integrated into the decoder, processor, or communication device.

For example, A / B can represent A or B. In the embodiments of this application, "and / or" is merely a description of the relationship between the related objects, indicating that there can be three relationships. For example, A and / or B can represent three cases: A exists alone, A and B exist simultaneously, and B exists alone. A and B can be singular or plural.

The embodiments of this application do not limit the number of access network devices, core network devices, and terminals included in this wireless communication system.

[0759] It is further understood that the wireless communication system of this application embodiment is a network that provides wireless communication functionality.

Based on factors such as capacity, speed, and latency, networks can be categorized into 2G (Generation) networks, 3G networks, 4G networks, future evolution networks, or future communication networks, such as the 5th Generation Wireless Communication System (5G) network. 5G networks can also be referred to as New Radio (NR), or in the next generation of wireless communication networks, such as the sixth generation (6G). For ease of description, this application may sometimes simply refer to wireless communication networks as "networks." The aforementioned wireless communication networks / systems also include radio access networks (RAN).

[0760] RAN can be a 3GPP-related cellular system, such as a 5G / NR mobile communication system, or a future-oriented evolution system / network.

The access network device can be a node in the radio access network, also known as a base station, or a radio access network (RAN) node (or device). The access network device can be an evolved NodeB (eNB or eNodeB) in LTE; or a next-generation NodeB (gNB) in a 5G network; or a base station in a future evolved public land mobile network (PLMN), a broadband network gateway (BNG), an aggregation switch, or a non-3GPP access device, etc. Optionally, the access network equipment in this application embodiment may include various forms of base stations, such as: macro base stations, micro base stations (also known as small stations), relay stations, access points, equipment implementing base station functions in communication systems evolved after 5G, access points (APs), transmitting and receiving points (TRPs), transmitting points (TPs) in WiFi systems, mobile switching centers, and equipment that performs base station functions in device-to-device (D2D), vehicle-to-everything (V2X), and machine-to-machine (M2M) communications.

This application embodiment does not specifically limit this.

[0762] The core network equipment involved in this application may include, in LTE, the Mobile Management Entity (MME) and Serving Gateway (S-GW); in 3G, the Service General Packet Radio Service Support Node (SGSN) and Gateway General Packet Radio Service Support Node (GGSN); in 5G, the Next Generation Core (NG-core); and the Sensing Function Entity as described in this application. It should be understood that the embodiments of this application do not limit the specific technologies or equipment forms used in the core network equipment.

[0763] In this application embodiment, the means for implementing the functions of the network device can be the network device itself, or a chip (or chip system) or other functional module capable of implementing the functions of the network device; for example, the chip or functional module is disposed in the network device. Other functional modules can be combined devices or components capable of implementing the functions of the network device. Optionally, the means for implementing the functions of the network device can also have virtual devices or software that possess the functions of the network device, such as a computer-readable storage medium, computer program product, etc., capable of executing methods related to the network device. The embodiments of this application do not limit the specific technology or specific device form adopted by the network device.

[0764] Furthermore, the terminal device involved in this application can also be referred to as a terminal device, user equipment (UE), mobile station (MS), mobile terminal (MT), etc., and is a device that provides voice and / or data connectivity to a user. For example, the terminal can be a handheld device with wireless connectivity, an in-vehicle device, a wearable device, etc. Currently, some examples of terminals include: smartphones (Mobile Phone), pocket personal computers (PPC), handheld computers, personal digital assistants (PDAs), laptops, tablets, wearable devices, or in-vehicle devices, etc. In addition, when it is a vehicle-to-everything (V2X) communication system, the terminal device can also be an in-vehicle device. It should be understood that the embodiments of this application do not limit the specific technology or specific device form used by the terminal.

[0765] In this application embodiment, the means for implementing the functions of the terminal device can be the terminal device itself, or a chip (or chip system) or other functional module, which can implement the functions of the terminal device. For example, the chip or functional module is disposed in the terminal device. Other functional modules can be combined devices or components that can implement the functions of the terminal device. Optionally, the means for implementing the functions of the terminal device can also have virtual devices or software that have the functions of the terminal device, such as a computer-readable storage medium, computer program product, etc., capable of executing methods related to the terminal device. The embodiments of this application do not limit the specific technology or specific device form adopted by the terminal device.

[0766] In this embodiment, the access network device and the terminal device can employ any feasible wireless communication technology to transmit data to each other. The transmission channel corresponding to the access network device sending data or control information to the terminal device is called the downlink channel (DL), and the transmission channel corresponding to the terminal device sending data or control information to the access network device is called the uplink channel (UL). It is understood that the access network device involved in this embodiment can be a base station. Of course, the access network device can also be any other possible access network device, and the terminal can be any possible terminal; this application does not impose any limitations.

[0767] Of course, any feasible wireless communication technology can be used between access network equipment and core network equipment, as well as between terminal equipment and core network equipment, to achieve mutual data transmission. The core network equipment can also be any other possible core network equipment; this application does not limit its use.

[0768] The perception scenario and the perception integration scenario can be applied to the above architecture. The core idea of ​​the perception integration technology is to add perception capabilities to the mobile communication network and build the ability to detect, monitor and image targets, so that the two capabilities of communication and perception are integrated into one network to achieve harmonious coexistence and even mutual benefit.

[0769] The technical principles of sensing differ somewhat from those of communication. Communication involves the transmitter modulating information onto radio waves and sending it to the receiver, which then demodulates the signal to obtain the information. Sensing, however, requires the transmitter to send radio waves in a specific direction. When these waves strike a target surface, they create an echo. The receiver then receives and processes this echo to obtain information such as the target's position, speed, and type. The echo can also be understood as a reflected radio wave.

[0770] Sensing can generally be divided into two modes: single-site sensing and dual-site sensing. In single-site sensing, the transmitting and receiving ends of the sensing signal are the same device. From the signal flow perspective, the sensing station both transmits and receives the signal reflected from the target surface. Therefore, single-site sensing is also called the self-transmitting and self-receiving mode. In dual-site sensing, the transmitting and receiving ends of the sensing signal are two different devices. From the signal flow perspective, after sensing station A transmits the sensing signal, the signal reflected from the target surface is received by sensing station B. Therefore, dual-site sensing is also called the A-transmitting and B-receiving mode. The single-site and dual-site sensing described above can also be called single-static sensing and dual-static sensing. Single-static sensing indicates that the transmitting and receiving sensing signals are located in the same network device or terminal device, while dual-static sensing indicates that the transmitting and receiving sensing signals are not in the same network device or terminal device.

[0771] As shown in Figure 4, Figure 4 is a schematic diagram of a communication scenario provided by an embodiment of this application. The sensing mode may specifically include modes such as network device self-transmitting and receiving sensing signals, terminal device self-transmitting and receiving sensing signals, network device A sending and network device B receiving sensing signals, terminal device A sending and terminal device B receiving sensing signals, network device sending and terminal device receiving sensing signals, and terminal device sending and network device receiving sensing signals.

[0772] The sensing target can be an object that needs to be sensed, such as a vehicle or building. It can also be called the target being sensed, a reflector, or a reflective surface; these terms are interchangeable. Essentially, it's an object that reflects sensing signals. The sensing node can be a node that needs to sense the target by sending and / or receiving sensing signals. Examples include access network devices, mobile phones, and in-vehicle devices. The sensing node wants to sense information such as the target's distance from itself, including factors like distance, angle, and speed.

[0773] The perception modes for sensing targets can include the following six modes. The corresponding perception nodes (perception merging) are also different in different modes.

[0774] The sensing nodes are between network devices, including sensing mode 1 and sensing mode 2.

[0775] Among them, the sensing mode 1 is for the network device to send and receive signals on its own. For example, the network device sends a sensing signal, the sensing signal is reflected after reaching the sensing target, and the network device also receives the reflected sensing signal, as shown in part (1) of Figure 4.

[0776] Sensing mode 2 is for the transmission of sensing signals between different network devices. For example, network device A sends a sensing signal and network device B receives the sensing signal. For instance, network device A sends a sensing signal, the sensing signal is reflected after reaching the sensing target, and then network device B receives the reflected sensing signal, as shown in part (3) of Figure 4.

[0777] The sensing nodes are between terminals, including sensing mode 3 and sensing mode 4.

[0778] Among them, the sensing mode 3 is for the terminal to send and receive signals on its own. For example, the terminal device sends a sensing signal, the sensing signal is reflected after reaching the sensing target, and the terminal device also receives the reflected sensing signal, as shown in part (2) of Figure 4.

[0779] Sensing mode 4 is for the transmission of sensing signals between different terminals. For example, terminal device A sends a sensing signal and terminal device B receives the sensing signal. For instance, terminal device A sends a sensing signal, the sensing signal is reflected after reaching the sensing target, and then terminal device B receives the reflected sensing signal, as shown in part (4) of Figure 4.

[0780] The sensing node is between network devices and terminals, including sensing mode 5 and sensing mode 6.

[0781] In sensing mode 5, the terminal device sends a sensing signal, and the network device receives the sensing signal. For example, the terminal device sends a sensing signal, the sensing signal is reflected after reaching the sensing target, and then the network device receives the reflected sensing signal, as shown in part (6) of Figure 4.

[0782] Sensing mode 6 involves the network device sending a sensing signal and the terminal device receiving the sensing signal. For example, the network device sends a sensing signal, and the terminal device receives the sensing signal. For example, the network device sends a sensing signal, the sensing signal is reflected after reaching the sensing target, and then the terminal device receives the reflected sensing signal, as shown in part (5) of Figure 4.

[0783] Please refer to Figure 5, which is a schematic diagram of the architecture of another communication system provided in an embodiment of this application. The communication system includes a first device, a second device, and a sensing target.

[0784] The first device can be a sensing transmitter, such as a network device or terminal device that transmits sensing signals. The sensing transmitter can be located in the same or different network device or terminal device as the sensing receiver. In the illustration of Figure 3, the first device is a terminal device, but this application does not limit this in practical applications.

[0785] The second device can be a sensing receiver, such as a network device or terminal device that receives sensing signals. The sensing receiver can be located in the same or different network device or terminal device as the sensing transmitter. In the illustration of Figure 3, the second device is a network device, but this application does not limit it in practical applications.

[0786] As an example, as shown in (1) of Figure 4, the first device and the second device can be the same device, which is a network device or a module (such as a chip) in the network device.

[0787] As another example, as shown in (2) of Figure 4, the first device and the second device can be the same device, which is a terminal device or a module (such as a chip) in the terminal device.

[0788] As another example, as shown in (3) of Figure 4, the first device and the second device can be different devices. For example, the first device is network device A or a module (such as a chip) in network device A, and the second device is network device B or a module (such as a chip) in network device B.

[0789] As another example, as shown in (4) of Figure 4, the first device and the second device can be different devices. For example, the first device is terminal device A or a module (such as a chip) in terminal device A, and the second device is terminal device B or a module (such as a chip) in terminal device B.

[0790] As another example, as shown in (5) of Figure 4, the first device and the second device can be different devices. For example, the first device is a network device or a module (such as a chip) in a network device, and the second device is a terminal device or a module (such as a chip) in a terminal device.

[0791] As another example, as shown in (6) of Figure 4, the first device and the second device can be different devices. For example, the first device is a terminal device or a module (such as a chip) in a terminal device, and the second device is a network device or a module (such as a chip) in a network device.

[0792] The perceived target, also known as the target being perceived, the target, etc., may include one or more scattering points. The characteristics of the target are derived based on the perceived signal. The perceived target illustrated in Figure 5 is a vehicle; however, this is merely an example and is not intended to limit the scope of the application.

[0793] The communication system also includes a third device, which is a device capable of configuring sensing configuration information for the first device (sensing transmitter) and / or the second device (sensing receiver). The third device can be a network device or a terminal device. Furthermore, the third device can be the same device as the first device (sensing transmitter), meaning the sensing transmitter configures the sensing configuration information for the sensing receiver; the third device can also be the same device as the second device (sensing receiver), meaning the sensing receiver configures the sensing configuration information for the sensing transmitter; or the third device can be different from both the first device (sensing transmitter) and the second device (sensing receiver), meaning a third party configures the sensing configuration information for the sensing transmitter and / or the sensing receiver.

[0794] The method provided in this application will now be described in detail with reference to the accompanying drawings. In the embodiments of this application, communication devices (including terminal devices and network devices) can perform some or all of the steps in the embodiments of this application. These steps or operations are merely examples, and the embodiments of this application can also perform other operations or variations thereof. Furthermore, the steps can be performed in different orders as presented in the embodiments of this application, and it is not necessary to perform all the operations in the embodiments of this application.

[0795] For example, the resource indication method provided in this application can be applied to sensing scenarios. Of course, it can also be applied to scenarios related to sensing, or scenarios derived from sensing; this application does not specifically limit the application scenarios. The above-mentioned exemplary application scenarios do not impose any limitations on the solution of this application.

[0796] The resource allocation method for sensing signals provided in this application embodiment is described in detail below with reference to Figure 6. This acquisition of sensing signal resources can be applied to the communication system shown in Figure 3 or Figure 5, and can also be applied to any of the scenarios in Figure 4; however, this application embodiment is not limited thereto.

[0797] The flowchart shown in Figure 6 illustrates the method from the perspective of communication device interaction, but this application does not limit the subject implementing the method. The method will be described below using the application of the above method to the first and second devices in the communication system shown in Figure 5 as examples. Exemplarily, the first device in Figure 5 can be a network device, a terminal device, or a chip, chip system, or processor that supports the implementation of the method on the network device, or a logic module or software that can implement all or part of the functions of the first device; the second device in Figure 5 can be a network device, a terminal device, or a chip, chip system, or processor that supports the implementation of the method on the second device, or a logic module or software that can implement all or part of the functions of the second device.

[0798] Figure 6 is a flowchart illustrating a resource allocation method provided in an embodiment of this application. As shown in Figure 6, the method may include steps S601 to S603. The steps shown in Figure 6 are described in detail below.

[0799] Step S601: The first device acquires at least one of the first time domain resources, the second time domain resources, or the third time domain resources.

[0800] In one possible implementation, at least one of the aforementioned first, second, or third time-domain resources may also be referred to as sensing resources, which include time-domain resources for carrying sensing signals. Optionally, the sensing resources may also include frequency-domain resources for carrying sensing signals.

[0801] The sensing resources include time-domain resources and frequency-domain resources used to carry the sensing signals. For example, the sensing signal is a sensing signal to be transmitted by the first device.

[0802] Optionally, the time-domain resources used to carry the sensing signal can also be referred to as the time-domain resources occupied or located by the sensing signal, or the time-domain resources of the sensing resources. Alternatively, the frequency-domain resources used to carry the sensing signal can also be referred to as the frequency-domain resources occupied or located by the sensing signal, or the frequency-domain resources of the sensing resources. In other words, determining the sensing resources can also be understood as determining the resources used to transmit the sensing signal.

[0803] Optionally, at least one of the aforementioned first, second, or third time-domain resources may be located within a sensing resource pool. This sensing resource pool may be a dedicated sensing resource pool, meaning it includes independent channels and time slots specifically for transmitting sensing signals; or, it may be a shared resource pool for sensing and communication.

[0804] Optionally, at least one of the first, second, or third time-domain resources may include at least one time unit in the time domain. For example, a time unit may be a symbol, time slot, micro-time slot, subframe, frame, radio frame, etc., and this application does not specifically limit it in this regard.

[0805] Optionally, the first device is a terminal device, and the first device acquires at least one of the following time-domain resources: a first time-domain resource, a second time-domain resource, or a third time-domain resource. Specifically, the terminal device may acquire the first time-domain resource; or...

[0806] The terminal device acquires the second time-domain resource; or,

[0807] Terminal devices acquire third-time domain resources; or,

[0808] The terminal device acquires any two of the following time-domain resources: the first time-domain resource, the second time-domain resource, or the third time-domain resource; or,

[0809] The terminal device acquires the first time domain resources, the second time domain resources, and the third time domain resources.

[0810] Optionally, the first device is a network device, and the first device acquires at least one time domain resource selected from a first time domain resource, a second time domain resource, or a third time domain resource. Specifically, the network device may acquire the first time domain resource; or...

[0811] Network devices acquire second time-domain resources; or,

[0812] Network devices acquire third-time domain resources; or,

[0813] Or, the network device acquires any two of the following time-domain resources: the first time-domain resource, the second time-domain resource, or the third time-domain resource; or,

[0814] Network devices acquire first time-domain resources, second time-domain resources, and third time-domain resources.

[0815] Optionally, the perceived resource configuration message indicates at least one of a first time-domain resource, a second time-domain resource, or a third time-domain resource.

[0816] For example, the first device and the third device can be the same device, meaning the first device can configure or indicate at least one of a first time-domain resource, a second time-domain resource, or a third time-domain resource. Accordingly, the acquisition by the first device can be understood as the first device determining the resource locally. Optionally, the first device can also configure or indicate at least one of the first, second, or third time-domain resources to the second device, enabling the second device to receive signals. For example, the first device sends a sensing resource configuration message to the second device. Correspondingly, the second device receives the sensing resource configuration message from the first device (or the third device).

[0817] For example, the second device and the third device can be the same device, meaning the second device can configure or indicate at least one of the first time-domain resources, the second time-domain resources, or the third time-domain resources. Correspondingly, the first device acquiring at least one of the first, second, or third time-domain resources can be understood as: the first device receiving the sensing resource configuration message from the second device, the sensing resource configuration message indicating at least one of the first, second, or third time-domain resources. The second device acquiring at least one of the first, second, or third time-domain resources can be understood as the second device locally determining at least one of the first, second, or third time-domain resources.

[0818] For example, the first device, the second device, and the third device can be three different devices. That is, the third device can configure / instruct at least one of the first, second, or third time-domain resources to the first device and / or the second device. Correspondingly, the first device acquiring at least one of the first, second, or third time-domain resources can be understood as: the first device receiving the sensing resource configuration message from the third device, whereby the sensing resource configuration message indicates at least one of the first, second, or third time-domain resources. The second device follows the same logic, and will not be elaborated further here.

[0819] In this embodiment of the application, the first time-domain resource is located after the first downlink time unit and / or before the first uplink time unit in the time domain;

[0820] The second time-domain resource is located after the second uplink time unit and / or before the second downlink time unit in the time domain.

[0821] The third time-domain resource is included if it is located after the last communication symbol in the third time unit, or before the first communication symbol in the third time unit, or if it is one or more cyclic prefixes in the third time unit.

[0822] It is understood that the aforementioned uplink time unit refers to the time unit used for uplink transmission. This uplink time unit can be an uplink subframe, an uplink timeslot, an uplink symbol, or an uplink symbol with flexible symbol configuration.

[0823] Accordingly, the aforementioned downlink time unit refers to the time unit used for downlink transmission, which can be a downlink subframe, downlink time slot, downlink symbol, or downlink symbol of a flexible symbol.

[0824] In the embodiments of this application, time slots and symbols are used to represent different time granularities. An uplink time slot can be replaced by a second uplink time unit, or an uplink symbol can be replaced by a first uplink time unit. Similarly, a downlink time slot can be replaced by a second downlink time unit, or a downlink symbol can be replaced by a first downlink time unit.

[0825] The first time domain resource, the second time domain resource, and the third time domain resource are described below.

[0826] First-time domain resources:

[0827] The first time-domain resource is located after the first downlink time unit and / or before the first uplink time unit in the time domain. Please refer to Figure 7, which is a schematic diagram of a first time-domain resource provided in an embodiment of this application.

[0828] The first time domain resource can be divided into three cases: Case 1, the first time domain resource is located after the first downlink time unit and before the first uplink time unit in the time domain; Case 2, the first time domain resource is specifically located after the first downlink time unit in the time domain; Case 3, the first time domain resource is specifically located before the first uplink time unit in the time domain.

[0829] Referring to Figure 7, in Case 1, the first time-domain resource is located after the first downlink time unit and before the first uplink time unit in the time domain. This means that, in the optional implementation, the first time-domain resource is situated within the time interval between the downlink and uplink time slots, enabling the transmission of sensing signals without affecting the normal transmission of communication signals. It should be understood that the time interval between the downlink and uplink time slots here represents the time interval between the downlink and uplink time units. Alternatively, the time interval between the downlink and uplink time units can also refer to the time interval between downlink frames and uplink frames, or the time interval between downlink symbols and uplink symbols.

[0830] In one optional implementation, the first uplink time unit includes at least one of an uplink frame, an uplink timeslot, a frame corresponding to the transmission of an uplink signal, a timeslot corresponding to the transmission of an uplink signal, an uplink transmission time unit, or a future-defined uplink time unit. For example, the first uplink time unit may be the uplink timeslot U in FIG7. It should be understood that the first uplink time unit may be the uplink timeslot U on the network device timeline or the uplink timeslot U on the terminal device timeline.

[0831] In one optional implementation, the first downlink time unit includes at least one of a downlink frame, a downlink time slot, a frame corresponding to the transmission of a downlink signal, a time slot corresponding to the transmission of a downlink signal, a downlink transmission time unit, or a future-defined uplink time unit. For example, the first downlink time unit may be downlink time slot D in FIG7. It should be understood that the first downlink time unit may be downlink time slot D on the network device timeline or downlink time slot D on the terminal device timeline.

[0832] It should be noted that in Case 1, the first time domain resource is located after the first downlink time unit and before the first uplink time unit, whether on the network device timeline (time domain resource line) or the terminal device timeline (time domain resource line).

[0833] It should be noted that in some implementations of the embodiments of this application, "used for" indicates a purpose, rather than the actual execution of the action. For example, the aforementioned uplink frame, uplink time slot, downlink frame, or downlink time slot can be a frame or time slot used for transmitting data / transmitting signals, including cases where data / signal transmission is configured but no data / signal is actually transmitted. The first uplink time unit and the first downlink time unit include the frame / time slot corresponding to the timeline on the terminal device side, specifically referring to the uplink time slot (time slot U) and downlink time slot (time slot D1, time slot D2) corresponding to the timeline on the terminal device side as shown in Figure 2.

[0834] For example, the first time-domain resource is located in the time domain between the downlink DL time slot and the uplink UL time slot.

[0835] The following explanation uses DL (downlink) to represent downlink and UL (uplink) to represent uplink for time-domain resources. It should be understood that a DL time slot can be a downlink time slot, the time slot containing the downlink signal, a downlink frame, or the frame containing the downlink signal; DL transmission can refer to transmitting the frame corresponding to the downlink signal or the time slot corresponding to the downlink signal. Similarly, UL time slots and UL transmissions can be uplink time slots, the time slot containing the uplink signal, an uplink frame, or the frame containing the uplink signal; UL transmission can refer to transmitting the frame corresponding to the uplink signal or the time slot corresponding to the uplink signal.

[0836] It is understood that the first uplink time unit includes UL timeslots or UL transmissions, which can be used interchangeably. The first downlink time unit includes DL timeslots or DL ​​transmissions, which can be used interchangeably.

[0837] In scenario two, considering that there might not be a first uplink time unit after the first downlink time unit, the first time-domain resource is specifically located after the first downlink time unit in the time domain. The aforementioned absence of a first uplink time unit can be understood as the configuration of a first uplink time unit, but the uplink signal was not transmitted within that first uplink time unit or the first uplink time unit was not configured. For a detailed description of the first time-domain resource being located after the first downlink time unit in the time domain, please refer to scenario one, which will not be repeated here.

[0838] In other words, the first time-domain resource is located in the time domain after the DL timeslot or DL ​​transmission. For example, the first time-domain resource is located in the time domain after the DL timeslot; the first time-domain resource is located in the time domain after the DL transmission.

[0839] It should be understood that the DL time slots and UL time slots in the embodiments of this application are merely examples. The DL time slots and UL time slots can be equivalently replaced by DL (downlink) time units and UL (uplink) time units, or DL ​​frames and UL frames, or DL ​​symbols and UL symbols. This will not be elaborated further in the following embodiments. The DL time slots and UL time slots involved in subsequent embodiments can still be equivalently replaced with the above description.

[0840] In scenario three, considering that a first downlink time unit may not exist before the first uplink time unit, the first time-domain resource is specifically located before the first uplink time unit in the time domain. The aforementioned absence of a first downlink time unit can be understood as the configuration of a first downlink time unit, but the downlink signal was not transmitted within that first downlink time unit or the first downlink time unit was not configured. For a detailed description of the first time-domain resource being located before the first uplink time unit in the time domain, please refer to scenario one, which will not be repeated here.

[0841] In other words, the first time-domain resource is located in the time domain before the UL timeslot or before the UL transmission. For example, the first time-domain resource is located in the time domain before the UL timeslot; the first time-domain resource is located in the time domain before the UL transmission.

[0842] In one alternative implementation, the first time-domain resource comprises at least M consecutive symbols, where M is a positive integer from 1 to 14. It should be understood that the first time-domain resource consists of at least M consecutive symbols following the first downlink time unit and / or preceding the first uplink time unit.

[0843] For example, the first time-domain resource is at least M consecutive symbols following the first downlink time unit, or at least M consecutive symbols preceding the first uplink time unit, or at least M consecutive symbols following and preceding the first downlink time unit. It should be noted that the descriptions of these three scenarios for the first time-domain resource are based on the timelines of the terminal device and / or network device. Referring to Figure 7, the first time-domain resource does not overlap with the first uplink time unit, and / or, the first time-domain resource does not overlap with the first downlink time unit; therefore, the first time-domain resource can be said to be located in the time domain after the first downlink time unit and / or before the first uplink time unit.

[0844] In one alternative implementation, the first time-domain resource is at least M consecutive symbols within a first time slot.

[0845] The first time slot is illustrated by example. The first time slot is a time slot used to transmit sensing signals. The first time slot may also be called a sensing time slot.

[0846] For example, the first time slot is a special time slot. This special time slot includes at least one of uplink symbols, downlink symbols, flexible symbols, and sensing symbols. Of course, in the case where the first time slot is a special time slot, this special time slot / first time slot includes at least M sensing symbols. Optionally, the special time slot / first time slot includes at least M consecutive sensing symbols. The aforementioned sensing symbols are symbols used to transmit sensing signals.

[0847] It is understandable that the first time slot can be divided into three cases: Case 1, the first time slot is located after the first downlink time unit and before the first uplink time unit in the time domain; Case 2, the first time slot is located after the first downlink time unit in the time domain; Case 3, the first time slot is located before the first uplink time unit in the time domain. Among them, Case 1, Case 2, and Case 3 correspond to the three cases of the first time domain resources.

[0848] It should be noted that the descriptions of the three scenarios for the first time slot mentioned above are based on the network device timeline. As shown in Figure 7, the special time slot S is located after the first downlink time unit and / or before the first uplink time unit on the network device timeline. Therefore, the first time slot can be said to be located after the first downlink time unit and / or before the first uplink time unit in the time domain.

[0849] In one alternative implementation, the first time slot includes some or all of the special time slots (also referred to as S-slots), or in other words, the first time slot includes at least a portion (slots / symbols) of the special time slots. It is understood that the first time-domain resource is some or all of the symbols in the special time slots. Please refer to Figure 7, which specifically illustrates the case where the first time slot is a special time slot. The shaded area in the special time slot (slot S) of Figure 7 represents the first time-domain resource, which is a portion of the symbols in the special time slot.

[0850] It should be understood that the case shown in Figure 7, where the first time-domain resource is a partial symbol in a special time slot, is merely an example and is not limited in this application.

[0851] Please refer to Figure 8, which is a schematic diagram of a first time slot provided in an embodiment of this application. In Figure 8, the first time slot is a special time slot or a portion of a special time slot. Optionally, the first time slot includes a first time domain resource, or the first time domain resource is located within the first time slot.

[0852] Figure 8 mainly illustrates the time domain resource line on the terminal device side when the second device is a terminal device, where the first time domain resource receives the sensing signal (e.g., the network device sends the signal and the terminal device receives it). The first time domain resource is located between the DL time slot and the UL time slot.

[0853] Accordingly, Figure 7 mainly illustrates the terminal device-side time domain resource line for transmitting sensing signals (e.g., self-transmission and self-reception by the terminal device) in the case where the first device is a terminal device. The first time domain resource is located between the DL time slot and the UL time slot.

[0854] Figures 7 and 8 also involve related content on transmit / receive conversion / transmit / receive conversion. The possible implementation and explanation of this part will be elaborated later, and will not be explained here.

[0855] The first time slot (sensing time slot) is introduced below.

[0856] The first time slot can be understood as the first time domain resource, or in other words, the time slot containing the first time domain resource. When the first time slot is the time slot containing the first time domain resource, the first time slot includes specific time slots, or in other words, the first time slot includes all of the specific time slots, or the first time slot is a specific time slot. When the first time slot is the first time domain resource, the first time slot includes a portion of the specific time slots. Optionally, the first time slot includes a portion or all of the specific time slots.

[0857] The special time slot used for transmitting sensing signals may include one or more time slots, or the first time slot used for transmitting sensing signals may include one or more time slots.

[0858] In some implementations of the embodiments of this application, a special time slot may include a first time domain resource, that is, a special time slot may be used to transmit sensing signals.

[0859] In Figures 7 and 8, a special time slot includes a first time domain resource, or in other words, the first time domain resource is at least M consecutive symbols in the special time slot.

[0860] The symbols (perceptual symbols) included in the first time-domain resource in the embodiments of this application will be described below.

[0861] In one alternative implementation, the first time-domain resource includes any one of the following:

[0862] The M consecutive symbols following the first downlink time unit;

[0863] The first M consecutive symbols following the first downlink time unit;

[0864] The M consecutive symbols preceding the first uplink time unit;

[0865] The last M consecutive symbols before the first uplink time unit.

[0866] The first M consecutive symbols following the first downlink time unit can refer to the M consecutive symbols following the last communication symbol of the first downlink time unit and adjacent to that last communication symbol.

[0867] Please refer to Figure 9, which is a schematic diagram of a sensing symbol provided in an embodiment of this application. In Figure 9, the sensing symbol is represented by P, and the sensing symbol is a symbol for transmitting sensing signals.

[0868] In Figure 9, the first downlink time unit is the downlink time slot, which mainly illustrates the first time domain resource including the first M consecutive symbols after the first downlink time unit, or the first time domain resource including the first M consecutive symbols after the downlink time slot. The first M consecutive symbols after the first downlink time unit can refer to the M consecutive symbols adjacent to the last communication symbol in the downlink time slot (symbol D indicated by the arrow in Figure 9).

[0869] In other words, the first M consecutive symbols after the first downlink time unit can refer to the first M consecutive symbols in a special time slot (or the first time slot).

[0870] It should be noted that the term "adjacent" as used above refers to the first symbol in the first M consecutive symbols being adjacent to the last communication symbol in the downlink time slot or downlink transmission.

[0871] The first M consecutive symbols following the first downlink time unit can refer to the first M consecutive symbols after the fourth duration, starting from the beginning of the special time slot (or the first time slot). The fourth duration is half the timing advance duration (e.g., 0.5T). TA It should be understood that the last communication symbol (downlink symbol) shown in Figure 9 is only an example within the downlink time slot. In a possible implementation, the last communication symbol (downlink symbol) may also be located in a special time slot in the time domain.

[0872] For example, the first M consecutive symbols following the first downlink time unit illustrated in Figure 9 can refer to the M consecutive symbols adjacent to the last communication symbol in the downlink time slot. In Figure 9, the M1 sensing symbols included in the first time-domain resource are located after the first downlink time unit in the time domain.

[0873] In other words, the first time-domain resource comprises M1 sensing symbols located after the first downlink time unit (downlink time slot) and adjacent to the last communication symbol (D) in the downlink time slot. In this case, the first time-domain resource comprises the first M (M1) consecutive symbols after the first downlink time unit, where M1 is a possible implementation of M and is any positive integer from 1 to 14.

[0874] For example, the first M consecutive symbols following the first downlink time unit can refer to the M consecutive symbols adjacent to the last communication symbol in the downlink transmission. Referring to Figure 10, the M1 sensing symbols included in the first time-domain resource are located after the first downlink time unit in the time domain. In other words, the M1 sensing symbols included in the first time-domain resource are located after the downlink transmission and are adjacent to the last communication symbol (D) in the downlink transmission.

[0875] As shown in Figure 2, the end position of the downlink time slot is 1 / 2 timing advance time (e.g., 0.5T) later than the start position of the special time slot (or the first time slot). TA Downlink transmission is still in progress during the fourth duration prior to the special time slot (or the first time slot). Therefore, the M1 sensing symbols included in the first time domain resource are the first M consecutive symbols after the fourth duration following the start position of the special time slot (or the first time slot). In this case, the first time domain resource includes the first M (M1) consecutive symbols after the first downlink time unit, where M1 is a possible implementation of M and is any positive integer from 1 to 14.

[0876] It should be understood that the first M consecutive symbols following the first downlink time unit are one possible implementation of the M consecutive symbols following the first downlink time unit. Alternatively, the M consecutive symbols following the first downlink time unit can be the first M, the middle M, or the last M.

[0877] The middle M symbols refer to cases where the sensing symbol is not adjacent to the last communication symbol in the first downlink time unit, and not adjacent to the first communication symbol in the first uplink time unit. Subsequent possible implementations involving the "before," "middle," and "last" symbols can refer to this description, and will not be elaborated upon further.

[0878] For example, the first downlink time unit is the downlink time slot, and the first time domain resource is M consecutive symbols after at least the fourth duration following the downlink time slot.

[0879] For example, the first downlink time unit is the time unit for downlink transmission, and the first time domain resource is the M consecutive symbols following the downlink transmission.

[0880] Optionally, the last M consecutive symbols before the first uplink time unit can refer to the M consecutive symbols preceding the first communication symbol of the first downlink time unit and adjacent to that first communication symbol. Please refer to Figure 11, which is a schematic diagram of another sensing symbol provided by an embodiment of this application.

[0881] In Figure 11, the sensing symbol is represented by P. Figure 11 mainly illustrates the last M consecutive symbols before the first uplink time unit. The last M consecutive symbols before the first uplink time unit can refer to the M consecutive symbols adjacent to the first communication symbol in the uplink time slot (symbol U indicated by the arrow in Figure 11).

[0882] In other words, the last M consecutive symbols before the first uplink time unit can refer to the last M consecutive symbols in a special time slot (or the first time slot).

[0883] Optionally, the last M consecutive symbols before the first uplink time unit can refer to the last M consecutive symbols before the fourth duration preceding the end of the special time slot (or the first time slot). In other words, the last M consecutive symbols before the first uplink time unit are separated from the uplink time slot by a fourth duration, or the last M consecutive symbols before the first uplink time unit are separated from the uplink time slot by at least a fourth duration.

[0884] Optionally, the fourth duration is half the duration of the timing advance (e.g., 0.5T). TA ).

[0885] It should be noted that the term "adjacent" as used above refers to the last symbol in the last M consecutive symbols being adjacent to the first communication symbol in the uplink time slot or uplink transmission.

[0886] For example, in Figure 11, the M2 sensing symbols included in the first time-domain resource are located before the first uplink time unit in the time domain and are adjacent to the first communication symbol (U) in the first uplink time unit. M2 is one possible implementation of M, and M2 is any positive integer from 1 to 14. M2 may be equal to or not equal to M1, and this application does not limit this.

[0887] For example, the last M consecutive symbols preceding the first uplink time unit can refer to the M consecutive symbols adjacent to the first communication symbol in the uplink transmission. Referring to Figure 12, the M² sensing symbols included in the first time-domain resource are located before the first uplink time unit in the time domain. In other words, the M² sensing symbols included in the first time-domain resource are located before the uplink transmission and are adjacent to the first communication symbol (D) in the uplink transmission.

[0888] As shown in Figure 2, the start position of the uplink time slot is 1 / 2 timing advance time (e.g., 0.5T) earlier than the end position of the special time slot (or the first time slot). TAUplink transmission has begun in the last fourth duration of the special time slot (or the first time slot). Therefore, the M2 sensing symbols included in the first time domain resource are the last M consecutive symbols preceding the fourth duration before the end of the special time slot (or the first time slot). In this case, the first time domain resource includes the last M (M2) consecutive symbols preceding the first uplink time unit, where M2 is a possible implementation of M and is any positive integer from 1 to 14.

[0889] It should be understood that the last M consecutive symbols before the first uplink time unit belong to one possible implementation of the M consecutive symbols before the first uplink time unit.

[0890] For example, the first uplink time unit is the uplink time slot, and the first time domain resource is the M consecutive symbols at least four time intervals before the uplink time slot.

[0891] For example, the first uplink time unit is the time unit for uplink transmission, and the first time domain resource is the M consecutive symbols preceding the uplink transmission.

[0892] It should be understood that the number of sensing symbols P in Figures 9 to 12 is merely an example and should not be taken as a limitation on the symbols used to transmit sensing signals in the embodiments of this application.

[0893] In one alternative implementation, the time interval between the first time domain resource and the first downlink time unit is greater than or equal to a first time, and / or the time interval between the first time domain resource and the first downlink time unit is greater than or equal to a second time.

[0894] Optionally, the first time is the time of the transmit / receive conversion; or, the first time is greater than or equal to the transmit / receive conversion time; or, the first time is a predefined time. The predefined time can be greater than or equal to the transmit / receive conversion time.

[0895] Optionally, the second time is the transmit-receive conversion time; or, the second time is greater than or equal to the transmit-receive conversion time; or, the second time is a predefined time. The predefined time can be greater than or equal to the transmit-receive conversion time.

[0896] Optionally, the time interval between the first time-domain resource and the DL timeslot is greater than or equal to the first time and / or the second time; or, the time interval between the first time-domain resource and the timeslot that can be used for DL ​​transmission is greater than or equal to the first time and / or the second time. Referring to Figure 8, the time interval between the first time-domain resource and the DL timeslot in Figure 8 is equal to the first time / second time. To allow more time for transmit / receive switching, this time interval can obviously also be greater than the first time / second time. Exemplarily, this implementation is applicable to sensing modes where the terminal device transmits and receives, the terminal device transmits and the network device receives, or the terminal device A transmits and the terminal device B receives.

[0897] In one alternative implementation, the time interval between the first time domain resource and the first uplink time unit is greater than or equal to a first time, and / or the time interval between the first time domain resource and the first uplink time unit is greater than or equal to a second time.

[0898] Optionally, the time interval between the first time domain resource and the UL time slot is greater than or equal to the first time and / or the second time; or, the time interval between the first time domain resource and the time slot that can be used for UL transmission is greater than or equal to the first time and / or the second time. It should be understood that, in order to allow more time for transmit / receive switching, this time interval can obviously be greater than the first time / second time. Exemplarily, this implementation is applicable to sensing modes where the terminal device transmits and receives, the terminal device transmits and the network device receives, or terminal device A transmits and terminal device B receives.

[0899] It should be noted that, in subsequent implementations, the relationship between the first time domain resource and the first time and / or the second time can be found in the relevant description of this implementation.

[0900] To more clearly illustrate the possible implementations of the first time-domain resource, the time-domain position of the first time-domain resource in the embodiments of this application satisfies any one of the following methods, or a combination of at least two. The following includes four methods: method a, method b, method c, and method d. The time-domain position of the first time-domain resource satisfying any one of these four methods, or a combination of at least two, means that the time-domain position of the first time-domain resource can only satisfy method a, only satisfy method b, or satisfy both method a and method b, or satisfy both method a and method d, etc. This application does not limit this. The four methods are as follows:

[0901] In method a, the first time-domain resource is located after the DL time slot.

[0902] The DL time slot is one possible implementation of the first downlink time unit; that is, the DL time slot can be replaced by the first downlink time unit. Optionally, mode a can also be that the first time domain resource is located after the downlink frame, after the downlink symbol, or after any future-defined downlink time unit. It should be understood that the time slots used in this embodiment are merely illustrative and not intended to limit the scope of the application. The use of time slots in other subsequent modes follows a similar principle and will not be elaborated further.

[0903] It should be noted that in the future field of communication, the downlink time unit may be redefined, such as a time unit smaller than a symbol or other newly emerging time units. However, regardless of the type of time unit, as long as it is related to downlink, the definition of the first time domain resource for the time domain position in the embodiments of this application can also be applied, and this will not be elaborated further.

[0904] Referring to Figures 7 and 8, the first time-domain resource and the DL time slot can be adjacent in the time domain, or the time slot containing the first time-domain resource and the DL time slot can be adjacent in the time domain. In Figures 7 and 8, the DL time slot is adjacent to the first time-domain resource in the time domain, both on the network device's timeline and on the terminal device's timeline. In Figures 7 and 8, the time slot containing the first time-domain resource and the DL time slot can be adjacent in the time domain, at least on the network device's timeline. This can be understood as the time slot index of the first time-domain resource and the DL time slot being adjacent, meaning the DL time slot index is adjacent. The implementation method for the first time-domain resource and the UL time slot being adjacent can be referred to here, and will not be elaborated further.

[0905] The first time-domain resource is located after the DL time slot. In other words, it is located after the time slot that can be used for DL ​​transmission. See Figures 7 and 8 for details; the shaded areas at DL in Figures 7 and 8 represent DL transmission. The time slot used for DL ​​transmission can refer to the DL time slot itself or to some special time slots. Considering that special time slots may contain downlink symbols used for transmitting downlink signals, the first time-domain resource is located after the downlink symbols used for transmitting downlink signals. Alternatively, the first time-domain resource is located after the special time slots used for transmitting downlink signals, or in other words, after some of the special time slots used for transmitting downlink signals.

[0906] Optionally, the first time-domain resource is located after the downlink frame, or the first time-domain resource is located after the downlink timeslot.

[0907] Optionally, the first time-domain resource is a specific time slot or M consecutive symbols within the first time slot.

[0908] Optionally, the first time-domain resource is located in the first M consecutive symbols after the DL timeslot, or the first time-domain resource is located in the first M consecutive symbols after the timeslot that can be used for DL ​​transmission. Exemplarily, this implementation is applicable to sensing modes where network devices transmit and receive independently, network transmitting terminal devices receive, or network device A transmits and network device B receives.

[0909] Optionally, the first time-domain resource is M consecutive symbols following the DL timeslot, or the first time-domain resource is M consecutive symbols following a timeslot that can be used for DL ​​transmission.

[0910] In this approach, as shown in Figures 7 and 8, the first time-domain resource can be followed by a UL time slot, or a resource for UL transmission, or a time-domain resource that can be used for UL transmission. For example, the first time-domain resource can be followed by a time-domain resource that can be used for UL transmission, but whether UL transmission occurs depends on the scheduling.

[0911] Optionally, the first time-domain resource includes M consecutive symbols preceding the UL timeslot; or, the first time-domain resource includes M consecutive symbols preceding the UL transmission; or, the first time-domain resource includes M consecutive symbols preceding the timeslot used for UL transmission; or, the first time-domain resource includes the last M consecutive symbols preceding the UL timeslot; or, the first time-domain resource includes the last M consecutive symbols preceding the UL transmission; or, the first time-domain resource includes the last M consecutive symbols preceding the timeslot that can be used for UL transmission. Exemplarily, this implementation is applicable to modes where the terminal device transmits and receives independently, the terminal device transmits and the network device receives, or the terminal device A transmits and the terminal device B receives.

[0912] Optionally, the first time-domain resource includes M consecutive symbols preceding the UL timeslot, or the first time-domain resource includes M consecutive symbols preceding the UL transmission, or the first time-domain resource includes M consecutive symbols preceding the timeslot that can be used for UL transmission. Considering that uplink and downlink switching requires a certain amount of time, the time interval between the first time-domain resource and the UL timeslot is greater than or equal to a first time and / or a second time, or the time interval between the first time-domain resource and the UL transmission is greater than or equal to the first time and / or the second time, or the time interval between the first time-domain resource and the timeslot that can be used for UL transmission is greater than or equal to the first time and / or the second time. Exemplarily, this implementation is in a mode where the network device transmits and receives, the network device transmits and the terminal device receives, or the network device A transmits and the network device B receives.

[0913] Optionally, the time interval between the first time domain resource and the DL time slot is greater than or equal to the sum of the first time and the second time.

[0914] In method b, the first time-domain resource is located after the DL transmission.

[0915] DL transmission is one possible implementation of the first downlink time unit; that is, DL transmission can be replaced by the first downlink time unit. Optionally, the first time-domain resource is located after the frame corresponding to the transmitted downlink signal, or the first time-domain resource is located after the time slot corresponding to the transmitted downlink signal, or the first time-domain resource is located after the time slot corresponding to the downlink signal, or the first time-domain resource is located after the frame corresponding to the downlink signal, or in other words, the first time-domain resource is located after any future-defined downlink time unit.

[0916] It should be noted that in actual signal transmission scenarios, due to transmit / receive switching or timing advance, there is a certain time interval between the time unit corresponding to the communication signal (including frames or time slots, etc.) and the time corresponding to the transmission of the communication signal or the timing of sending (receiving) the communication signal. For details, please refer to Figure 13 and the explanation in item 9 of the aforementioned glossary, "Frame Start Time and Transmission Start Time." In Figure 13, the downlink frame end time is the end time of the corresponding time slot / frame configured for the downlink signal. However, considering timing advance, the downlink transmission end time can be relatively later than the downlink frame end time, with a first / second time interval between them. In some possible implementations, the transmission of the sensing signal occurs after the DL transmission. It should be understood that DL transmission can be used to refer to the downlink transmission end time or the frame / time slot corresponding to the downlink transmission.

[0917] Optionally, the first device is a terminal device. In mode b, DL transmission can be replaced by DL transmission of the terminal device or DL ​​signal transmission of the terminal device.

[0918] Please refer to Figures 7 and 8. In Figures 7 and 8, the first time-domain resource and the DL transmission (the shaded part of time slot D represents the DL transmission) can be adjacent in the time domain, or the time slot where the first time-domain resource is located can be adjacent in the time domain, or the time slot where the first time-domain resource is located can be adjacent in the time domain, or the time slot where the first time-domain resource is located can be adjacent in the time domain.

[0919] The first time-domain resource is located after the DL transmission; in other words, it is located after a time slot that can be used for DL ​​transmission. The first time-domain resource is M consecutive symbols within a specific time slot or a first time slot (sensing time slot). The time slot containing the first time-domain resource can be temporally adjacent to the time slot containing the DL transmission, or vice versa.

[0920] Optionally, the first time-domain resource is located in the first M consecutive symbols after the DL transmission, or the first time-domain resource is located in the first M consecutive symbols after the time slot that can be used for DL ​​transmission. Exemplarily, this implementation is in a mode where the network device transmits and receives, the network device transmits and the terminal device receives, or network device A transmits and network device B receives.

[0921] Optionally, the first time-domain resource is M consecutive symbols following the DL transmission, or the first time-domain resource is M consecutive symbols following the time slot where the DL transmission occurs. The time interval between the first time-domain resource and the DL transmission is greater than or equal to a first time and / or a second time, or the time interval between the first time-domain resource and the time slot where the DL transmission occurs is greater than or equal to a first time and / or a second time. Exemplarily, this implementation is applicable to sensing modes where the terminal device transmits and receives data, the terminal device transmits and the network device receives data, or terminal device A transmits and terminal device B receives data.

[0922] In this approach, the first time-domain resource can be followed by a UL time slot. In other words, the first time-domain resource can be followed by a resource for UL transmission, or the first time-domain resource can be followed by a time-domain resource that can be used for UL transmission. For example, the first time-domain resource can be followed by a time-domain resource that can be used for UL transmission, but whether there is UL transmission depends on the scheduling.

[0923] Optionally, the first time-domain resource is located in the last M consecutive symbols before the UL timeslot, or the first time-domain resource is located in the last M consecutive symbols before the UL transmission, or the first time-domain resource is located in the last M consecutive symbols before the timeslot that can be used for UL transmission. Exemplarily, this implementation is in a mode where the terminal device transmits and receives, the terminal device transmits and the network device receives, or the terminal device A transmits and the terminal device B receives.

[0924] Optionally, the first time domain resource is located in the M consecutive symbols preceding the UL timeslot, or the first time domain resource is located in the M consecutive symbols preceding the UL transmission, or the first time domain resource is located in the M consecutive symbols preceding the timeslot that can be used for UL transmission.

[0925] Considering that uplink and downlink switching requires a certain amount of time, the time interval between the first time domain resource and the UL time slot is greater than or equal to the first time and / or the second time; or, the time interval between the first time domain resource and the UL transmission is greater than or equal to the first time and / or the second time; or, the time interval between the first time domain resource and the time slot that can be used for UL transmission is greater than or equal to the first time and / or the second time. For example, this implementation is in a mode where the network device transmits and receives automatically, the network device transmits and the terminal device receives, or network device A transmits and network device B receives.

[0926] Optionally, the time interval between the first time domain resource and the DL transmission is greater than or equal to the sum of the first time and the second time.

[0927] In method c, the first time-domain resource is located before the UL time slot.

[0928] The UL time slot is one possible implementation of the first uplink time unit; that is, the UL time slot can be replaced by the first uplink time unit. In other words, the first time-domain resource is located before the uplink time slot, or before the uplink frame, or before a future-defined uplink time unit. It should be noted that in future communication applications, the uplink time unit may be redefined, for example, a time unit smaller than a symbol may appear, or other newly emerging time units may emerge. However, regardless of the type of time unit, as long as it is related to uplink, the relevant definitions of the time-domain position of the first time-domain resource in this application embodiment can also be applied, and this will not be elaborated further below.

[0929] Specifically, the first time-domain resource and the UL time slot can be adjacent in the time domain, or the time slot where the first time-domain resource is located can be adjacent in the time domain to the UL time slot.

[0930] The first time-domain resource is located before the UL timeslot, or it is located before a timeslot that can be used for UL transmission. The first time-domain resource is M consecutive symbols within a special timeslot or a first timeslot (sensing timeslot).

[0931] Optionally, the first time-domain resource is located in the last M consecutive symbols preceding the UL timeslot, or the first time-domain resource is located in the last M consecutive symbols preceding the timeslot that can be used for UL transmission. Exemplarily, this implementation is applicable to sensing modes where the terminal device transmits and receives data, the terminal device transmits and the network device receives data, or the terminal device A transmits and the terminal device B receives data.

[0932] Optionally, the first time-domain resource is located M consecutive symbols preceding the UL timeslot, or the first time-domain resource is located M consecutive symbols preceding the timeslot that can be used for UL transmission. The time interval between the first time-domain resource and the UL timeslot is greater than or equal to the first time unit and / or the second time unit, or the time interval between the first time-domain resource and the timeslot that can be used for UL transmission is greater than or equal to the first time unit and / or the second time unit. Exemplarily, this implementation is applicable to sensing modes where the network device transmits and receives automatically, the network device transmits and the terminal device receives, or the network device A transmits and the network device B receives.

[0933] In this approach, the first time-domain resource can be preceded by a DL time slot, or by a resource used for DL ​​transmission, or by a time-domain resource that can be used for DL ​​transmission. For example, the first time-domain resource can be preceded by a time-domain resource that can be used for DL ​​transmission, but whether DL transmission occurs depends on the scheduling.

[0934] Optionally, the first time-domain resource is located in the first M consecutive symbols after the DL timeslot, or the first time-domain resource is located in the first M consecutive symbols after the DL transmission, or the first time-domain resource is located in the first M consecutive symbols after the timeslot that can be used for DL ​​transmission. Exemplarily, this implementation is applicable to sensing modes where the network device transmits and receives, the network device transmits and the terminal device receives, or the network device A transmits and the network device B receives.

[0935] Optionally, the first time-domain resource is located M consecutive symbols after the DL timeslot, or the first time-domain resource is located M consecutive symbols after the DL transmission, or the first time-domain resource is located M consecutive symbols after the timeslot that can be used for DL ​​transmission. The time interval between the first time-domain resource and the DL timeslot is greater than or equal to the first time-domain resource, or the time interval between the first time-domain resource and the DL transmission is greater than or equal to the first time-domain resource, or the time interval between the first time-domain resource and the timeslot that can be used for DL ​​transmission is greater than or equal to the first time-domain resource. Exemplarily, this implementation is applicable to sensing modes where the terminal device transmits and receives data, the terminal device transmits and the network device receives data, or the terminal device A transmits and the terminal device B receives data.

[0936] Optionally, the time interval between the first time domain resource and the UL time slot is greater than or equal to the sum of the first time and the second time.

[0937] In mode d, the first time-domain resource is located before the UL transmission.

[0938] UL transmission is one possible implementation in the first uplink time unit, meaning that UL transmission can be replaced by the first uplink time unit.

[0939] The first time domain resource is located before the frame corresponding to the transmission of the uplink signal, or the first time domain resource is located before the time slot corresponding to the transmission of the downlink signal, or the first time domain resource is located before the time slot corresponding to the uplink signal, or the first time domain resource is located before the frame corresponding to the uplink signal, or in other words, the first time domain resource is located before any uplink time unit defined in the future.

[0940] Specifically, the first time-domain resource and the UL transmission can be adjacent in the time domain, or the time slot where the first time-domain resource is located can be adjacent in the time domain, or the time slot where the first time-domain resource is located can be adjacent in the time domain, or the time slot where the first time-domain resource is located can be adjacent in the time domain.

[0941] The first time domain resource is located before UL transmission, or the first time domain resource is located before a time slot that can be used for UL transmission.

[0942] It should be noted that in actual signal transmission scenarios, due to transmit / receive switching or timing advance, there is a certain time interval between the time unit (including frames or time slots, etc.) corresponding to the communication signal and the time corresponding to the transmission of the communication signal or the timing of sending (receiving) the communication signal, as shown in Figure 13. In Figure 13, the start time of the uplink frame must take into account the transmit / receive switching, and the actual end position of the uplink signal transmission is relatively late. The transmission of the sensing signal, in some possible implementations, occurs before the UL transmission. It should be understood that the UL transmission involved in the embodiments of this application can be the uplink transmission illustrated in Figure 13, or the frame corresponding to the uplink transmission, or the time slot corresponding to the uplink transmission, or the start time of the uplink transmission (e.g., the uplink transmission start time illustrated in Figure 13). The same applies to downlink transmission, which will not be elaborated here.

[0943] Optionally, the first device is a terminal device. In mode d, UL transmission can be replaced by UL transmission of the terminal device or UL signal transmission of the terminal device.

[0944] The first time-domain resource is M consecutive symbols within a specific time slot or a first time slot (sensing time slot). Optionally, the first time-domain resource is located after the M consecutive symbols preceding UL transmission, or the first time-domain resource is located after the M consecutive symbols preceding a time slot that can be used for UL transmission. Exemplarily, this implementation is in a mode where the terminal device transmits and receives, the terminal device transmits and the network device receives, or the terminal device A transmits and the terminal device B receives.

[0945] Optionally, the first time-domain resource is M consecutive symbols preceding the UL transmission, or the first time-domain resource is M consecutive symbols preceding the time slot where the UL transmission occurs. The time interval between the first time-domain resource and the UL transmission is greater than or equal to a first time and / or a second time. For example, this implementation is in a mode where the network device transmits and receives automatically, the network device transmits and the terminal device receives, or network device A transmits and network device B receives.

[0946] The first time-domain resource can be preceded by a DL time slot, or it can be preceded by a resource used for DL ​​transmission, or it can be preceded by a time-domain resource that can be used for DL ​​transmission. For example, the first time-domain resource can be preceded by a time-domain resource that can be used for DL ​​transmission, but whether DL transmission occurs depends on the scheduling.

[0947] Optionally, the first time-domain resource is located in the first M consecutive symbols after the DL timeslot, or the first time-domain resource is located in the first M consecutive symbols after the DL transmission, or the first time-domain resource is located in the first M consecutive symbols after the timeslot that can be used for DL ​​transmission. Exemplarily, this implementation is in a mode where the network device transmits and receives, the network device transmits and the terminal device receives, or network device A transmits and network device B receives.

[0948] Optionally, the first time-domain resource is located M consecutive symbols after the DL timeslot, or the first time-domain resource is located M consecutive symbols after the DL transmission, or the first time-domain resource is located M consecutive symbols after a timeslot that can be used for DL ​​transmission. The time interval between the first time-domain resource and the DL timeslot is greater than or equal to a first time and / or a second time, or the time interval between the first time-domain resource and the DL transmission is greater than or equal to the first time and / or the second time, or the time interval between the first time-domain resource and the timeslot that can be used for DL ​​transmission is greater than or equal to the first time and / or the second time. Exemplarily, this implementation is applicable to sensing modes where the terminal device transmits and receives data, the terminal device transmits and the network device receives data, or the terminal device A transmits and the terminal device B receives data.

[0949] Optionally, the time interval between the first time domain resource and the UL transmission is greater than or equal to the sum of the first time and the second time.

[0950] Optionally, the time interval between the first time domain resource and the first uplink time unit / second uplink time unit in modes a to d can also refer to the relevant descriptions in the aforementioned implementations involving time intervals and the first / second time.

[0951] At least two of the above four methods can be combined in pairs. For example, methods a and c can be combined, and methods b and d can be combined. Specifically, the first time-domain resource satisfying at least two of the above four methods includes: the first time-domain resource being located after the DL time slot and before the UL time slot in the time domain; or the first time-domain resource being located after the DL transmission and before the UL transmission in the time domain; or the first time-domain resource being located after the DL transmission and before the UL time slot in the time domain; or the first time-domain resource being located after the DL time slot and before the UL transmission in the time domain; or the first time-domain resource being located between the DL time slot and the UL transmission of the terminal device in the time domain.

[0952] It should be understood that the time-domain resources configured for different sensing signals may be different or the same. For example, sensing signal 1 uses a first time-domain resource that is time-domain located after the DL time slot and before the UL time slot. Sensing signal 2 also uses a first time-domain resource that is time-domain located after the DL time slot and before the UL time slot. Sensing signal 3 uses a first time-domain resource that is time-domain located after DL transmission and before UL transmission. Sensing signals 1, 2, and 3 are different sensing signals. Sensing signals 1 and 2 may use the same first time-domain resource; if transmitted simultaneously, it may be on different frequency domain resources of the first time-domain resource. Alternatively, sensing signals 1 and 2 may use different first time-domain resources than sensing signal 3.

[0953] Optionally, the time slot where the first time domain resource and the uplink signal transmission (of the terminal device) are located can be adjacent in the time domain or not adjacent in the time domain.

[0954] Optionally, the time slot in which the first device sends the sensing signal is between the DL time slot and the UL time slot, and is the last time slot before the UL transmission of the first device. For example, the first device is a terminal device.

[0955] Optionally, the first time-domain resource is located between the DL time slot and the UL time slot, and is the last M symbols before the UL transmission of the terminal device.

[0956] Optionally, UL transmission can be the transmission of data information of the terminal device (e.g., PUSCH) and / or the transmission of control information of the terminal device (e.g., PUCCH or Hybrid Automatic Repeat Request Acknowledgement (HARQ-ACK)).

[0957] Optionally, the first time-domain resource is located in the time domain between the DL time slot and the UL time slot before the UL transmission. In other words, a sensing signal can be transmitted between the DL time slot and the UL time slot before the UL transmission; or, a sensing signal can be transmitted in a time slot adjacent to the UL transmission and located before the UL transmission; or, a sensing signal can be transmitted in a time slot adjacent to the DL transmission and located after the DL transmission.

[0958] For example, if the terminal device transmits an uplink signal in time slot 2, where time slot 2 is the uplink time slot and time slot 0 is the downlink time slot, then a sensing signal can be transmitted in time slot 1.

[0959] For example, if a terminal device transmits an uplink signal in time slot 3 (uplink time slot) and time slot 0 (downlink time slot), then a sensing signal can be transmitted in time slot 1 and / or time slot 2.

[0960] In one optional implementation, the aforementioned first downlink time unit (including any possible case of the first downlink time unit) and first uplink time unit (including any possible case of the first uplink time unit) refer to the time units on the timeline (time domain resource line) of the terminal device side. The corresponding downlink and uplink time units on the network device side deviate from the first downlink and first uplink time units due to timing advance. Specifically, please refer to Figure 2. The time slot D1 on the network device side and the time slot D1 on the terminal device side have a timing advance difference of 1 / 2 on the actual time scale. The time slot D2 on the network device side and the time slot D2 on the terminal device side also have a timing advance difference of 1 / 2 on the actual time scale. There is a time difference of 1 / 2 timing advance between the time slot U on the network device side and the time slot U on the terminal device side in the actual time scale. However, the time slot U on the terminal device side is 1 / 2 timing advance compared to the time slot U on the network device side. For the time slots D1 and D2 on the terminal device side, they are later than those on the network device side.

[0961] Furthermore, the second uplink time unit, the second downlink time unit, and the third time unit involved in the embodiments of this application can all be regarded as time units on the time domain resource line corresponding to the terminal device. In this case, the first device is the terminal device.

[0962] In one optional implementation, by defining the time interval between the first time-domain resource and the first uplink / downlink time unit, effective isolation between the sensing signal transmission period and the normal communication period is ensured, leaving a certain amount of resource space for the transmission and reception of communication signals. The time interval between the first time-domain resource and the first downlink time unit is greater than or equal to the first time, and / or, the time interval between the first time-domain resource and the first uplink time unit is greater than or equal to the first time, and / or, the time interval between the first time-domain resource and the first downlink time unit is greater than or equal to the second time, and / or, the time interval between the first time-domain resource and the first uplink time unit is greater than or equal to the second time; the first time is located before and / or after the first time-domain resource in the time domain, and the second time is located before and / or after the first time-domain resource in the time domain.

[0963] In one alternative implementation, the first device is a terminal device, and terminal devices with the same timing advance group (TAG) can transmit sensing signals on the first time domain resource. Alternatively, uplink transmissions with the same TAG can transmit sensing signals on the first time domain resource.

[0964] For example, if the fourth device and the first device have the same timing advance group, then both the fourth device and the first device can send sensing signals on the first time domain resource.

[0965] Specifically, terminal devices with the same tag can transmit sensing signals on M symbols within a special time slot, or UEs with the same tag can transmit sensing signals on M symbols within a first time slot (sensing time slot). M is any positive integer from 1 to 14, for example, M = {1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14}. The special time slot is located in the time domain between the DL time slot and the UL time slot, or the first time slot is located in the time domain between the DL time slot and the UL time slot.

[0966] In one alternative implementation, the timing advance N can be determined based on the duration of the first time-domain resource. TA The value, or, can be based on a timed advance of N. TA The value of determines the duration of the first time-domain resource. Due to the timing advance T... TA It is determined by timed advance N TA In other words, it can be understood that the timing advance T can be determined based on the duration of the first time domain resource. TA The value, or, can be based on a time advance of T. TA The value determines the duration of the first time domain resource.

[0967] Due to the timing advance T TA The value corresponds to the maximum communication distance between the first device and the third device. The timing advance T can be determined based on the duration of the first time-domain resource (first duration). TA The value can also be understood as: the maximum communication distance between the first device and the third device can be determined based on the duration of the first time domain resource (first duration). Correspondingly, it can also be based on the timing advance T. TA The value determines the duration of the first time domain resource (first duration), which can also be understood as: the duration of the first time domain resource (first duration) can be determined based on the maximum communication distance between the first device and the third device.

[0968] In one optional implementation, as shown in Figures 7 and 8, there is a transmit / receive switch / transmit / receive switch in the time slot (such as the first time slot or a special time slot) where the first time domain resource is located, and / or timing advance. The first duration of the first time domain resource and the second duration of timing advance satisfy the following relationship:

[0969] T1≥T sensing +T TA Or, T1≥T sensing +T TA +N TA,offset ·T c

[0970] Where T1 represents the duration of A special time slots or A first time slots, A is a positive integer greater than or equal to 1, and T... sensing T represents the first duration of the resource in the first time domain. TA N is the second duration of the timed advance. TA,offset ·T c For the first and / or second time.

[0971] In the embodiments of this application, T TA,offset With N TA,offset ·T c Equal, both indicating the first and / or second time. That is, T TA,offset With N TA,offset ·T c They can be substituted for each other.

[0972] The following sections explain the correspondence between the first duration of the first time domain resource and the second duration of the time advance, specifically including cases four, five, and six.

[0973] The above three scenarios include reserving time for transmit / receive conversion and / or transmit / receive conversion before the first time domain resource; reserving time for transmit / receive conversion and / or transmit / receive conversion after the first time domain resource; and reserving time for transmit / receive conversion and / or transmit / receive conversion before and after the first time domain resource.

[0974] For example, in case four, the time domain / duration and timing advance N of the sensed signal TA The relationship between them satisfies the following formula:

[0975] T1≥T sensing +T TA Or, T1≥T sensing +(N TA +N TA,offset )T c

[0976] Where T1 represents the duration of A special time slots or A first time slots, A is a positive integer greater than or equal to 1, and T...sensing N represents the first duration of the resource in the first time domain. TA Indicator timing advance (N) TA ·T c (The fourth time interval before the scheduled start time), N TA,offset Indicate the first and / or second time (N) TA,offset ·T c (The duration of the first and / or second time intervals), T TA The second duration is the timed advance.

[0977] It can be understood that the first time-domain resource includes M symbols, and the first duration of the first time-domain resource is the duration corresponding to the M symbols.

[0978] Furthermore, in case four, T1≥T sensing +(N TA +N TA,offset )T c N in TA ·T c It can also be replaced with T TA .

[0979] In other words, in scenario four, within A special time slots or A first time slots, the timing is advanced by N. TA The longer the duration T of the first time domain resource, the more... sensing The shorter.

[0980] Specifically, the first time-domain resource can be located before the first time and / or the second time; or, the first time-domain resource can also be located after the first time and / or the second time; or, the first time-domain resource can be located before the first time and after the first time. In other words, transmit-receive conversion can be performed before sending the sensing symbol, after sending the sensing symbol, or both before and after sending the sensing symbol. Alternatively, transmit-receive conversion can be performed before sending the sensing symbol, after sending the sensing symbol, or both before and after sending the sensing symbol.

[0981] For example, the time T is advanced TA or N TA The value can be determined based on the duration of the first time domain resource (first duration).

[0982] For example, SCS = 15kHz, A = 1, T sensing If M = 1 symbol, then the timing T is satisfied in advance. TA ≤1532, or N TA ≤1569645.

[0983] For example, SCS = 15kHz, A = 1, Tsensing If M = 2 symbols, then the timing will be advanced to satisfy T. TA ≤1395, or N TA ≤1429211.

[0984] For example, SCS = 30kHz, A = 1, T sensing If M = 1 symbol, then the timing T is satisfied in advance. TA ≤1282, or N TA ≤656822.

[0985] For example, SCS = 30kHz, A = 1, T sensing If M = 2 symbols, then the timing will be advanced t...
