Description

Perception method, communication device and system

[0001] This application claims priority to the Chinese patent application filed with the State Intellectual Property Office of China on November 3, 2023, with application number 202311466042.X and application name “Perception Method, Communication Device and System”, the entire contents of which are incorporated by reference into this application. Technical Field

[0002] The present application relates to the field of communication technology, and more specifically, to a perception method, a communication device, and a system. Background Art

[0003] Positioning is one of the capabilities of perception. 5G new radio (NR) has standardized air interface positioning. The core network supports positioning management functions for resource coordination and scheduling related to positioning, determination of target location, and speed estimation and measurement accuracy of measurement signals. The positioning management function is located in the core network and can respond to positioning requirements from external or terminal devices. In addition, terminal devices in the radio resource control (RRC) connected state or RRC inactive state need to participate in the positioning process, such as participating in information transmission and reception, for example, measuring and reporting the positioning reference signal sent by the network device, or sending a sounding reference signal (SRS) to the network device.

[0004] Currently, existing perception processes (such as positioning) require extensive signaling interactions between network devices and terminal devices. For example, the network device sends a positioning reference signal (PRS) to the terminal device, the terminal device measures the PRS, and reports the PRS measurement results to the network device. However, these processes do not allow terminal devices to independently complete perception tasks.

[0005] Summary of the Invention

[0006] The present application provides a perception method, a communication device, and a system that can support terminal devices to complete perception tasks relatively independently.

[0007] In a first aspect, a perception method is provided, which is applied to a first device, including: receiving first configuration information and second configuration information, the first configuration information being used to indicate the configuration of a first perception signal, and the second configuration information being used to indicate the transmission configuration of a measurement result of the first perception signal, the first perception signal being a signal spontaneously transmitted and received by the first device; and sending the measurement result of the first perception signal according to the second configuration information.

[0008] The execution entity of the solution described in the first aspect may be the first device, a module of the first device (such as a chip system), or a logical node, logic module, or software that can implement all or part of the functions of the first device, without limitation. For ease of description, the following description uses the first device as an example.

[0009] In the above scheme, the first device completes the perception task based on the configuration information about the perception signal sent by the second device (including the transmission of the perception signal and the transmission of the measurement result of the perception signal). In this way, this can support the first device to complete the perception task more independently.

[0010] In addition, there is no need for much signaling interaction between the first device and the second device, thereby reducing the signaling interaction overhead between the first device and the second device for completing the perception task.

[0011] In a possible implementation of the first aspect, the method further includes: receiving third configuration information, where the third configuration information is used to indicate a measurement method of the first perception signal.

[0012] When a measurement method for the first perception signal is indicated, the first device may measure the first perception signal according to the indicated measurement method. In this manner, the first device may transmit a measurement result of the first perception signal that meets the requirements of the second device to the second device. In one possible implementation of the first aspect, the method further includes: receiving first information indicating a constraint condition, wherein the device meeting the constraint condition performs at least one of the perception measurement and capability reporting.

[0013] By limiting the number of devices that meet the constraints to perform at least one of the sensing measurement and capability reporting, interference between different devices can be reduced. In other words, by configuring the constraints, embodiments of the present application can avoid resource conflicts caused by too many devices competing for resources when reporting measurement results, thereby affecting the second device's reception of the sensing signal measurement results.

[0014] In the first aspect, in a possible implementation, the method further includes: receiving first information, the first information being used to request feedback capability information, the capability information being used to indicate the capability of the first device to associate with the first perception signal; and sending the capability information.

[0015] By reporting the capability information of the first device, the second device can configure the transmission, measurement, and reporting of the perception signal for the first device according to the capability of the first device, which can enable the first device to better complete the perception task.

[0016] Specifically, the capability information of the first device can be used by the second device to configure corresponding first configuration information and second configuration information for the first device according to the capability of the first device, so that the first device can better complete the perception task within its capability.

[0017] In the first aspect, a possible implementation method of sending capability information includes: sending capability information by means of a preamble and a payload; or sending capability information by means of a preamble.

[0018] For example, the first device randomly selects a preamble code and its corresponding channel from the preamble code resource pool configured by the second device to send the capability information of the first device to the second device. The channel carries a payload for carrying the capability information of the first device, and the preamble code is used to distinguish different first devices.

[0019] For example, when the capability information of the first device requires less information to indicate, the first device may select a preamble matching its capabilities from a preamble resource pool based on a predefined or preconfigured relationship between preambles and capabilities, and transmit the capability information of the first device to the second device. The number of preambles matching the capability information may be greater than one to reduce conflicts when different first devices select the same preamble.

[0020] If the first device is a non-connected device, the first device can send the capability information of the first device via a preamble and a payload, or the first device can send the capability information of the first device via a preamble, which can reduce latency and signaling interaction overhead.

[0021] If the first device is a connected device, the first device can also send the capability information of the first device to the second device through an uplink or side link. When the first device uses a preamble + payload or a preamble to send the capability information of the first device, this can reduce latency and signaling interaction overhead.

[0022] In the first aspect, a possible implementation method is to send a measurement result of a first perception signal based on the first information, including: determining a first parameter based on the bandwidth capability of the first device, the first configuration information including at least one parameter, and the at least one parameter including the first parameter; and transmitting the first perception signal based on the first parameter.

[0023] The second device can configure corresponding parameters for transmitting perception signals according to the bandwidth capabilities of different devices, and the first device can determine appropriate parameters for transmitting the first perception signal according to its own bandwidth capabilities, which can enable each device to better perform perception tasks within the bandwidth range.

[0024] In the first aspect, a possible implementation method is to send a measurement result of a first perception signal according to the first information, including: determining a first resource according to a first parameter, the second configuration information is used to configure at least one resource, the at least one resource including the first resource; and sending the measurement result of the first perception signal through the first resource.

[0025] The second device can configure one or more resources for transmitting the measurement results of the perception signal according to different parameters for transmitting the perception signal, which can enable different devices to select different resources when performing resource selection, thereby avoiding resource conflicts.

[0026] In addition, since the first parameter is associated with the first resource, when the first device sends the measurement result of the first perception signal to the second device through the first resource, the second device can determine the first parameter selected by the first device based on the first resource. This can prevent the first device from reporting the parameters selected for transmitting the first perception signal to the second device, thereby reducing signaling interaction overhead.

[0027] In the first aspect, a possible implementation method is to send the measurement result of the first perception signal according to the first information, including: determining the second resource according to the bandwidth capability of the first device, the second configuration information is used to configure at least one resource, and the at least one resource includes the second resource; sending the measurement result of the first perception signal through the second resource.

[0028] The first device sends the measurement result of the first perception signal by using the second resource corresponding to the bandwidth capability, which helps the second device obtain the bandwidth corresponding to the measurement result of the first perception signal through the second resource, without the first device carrying the bandwidth in the measurement result of the first perception signal, thereby reducing the signaling indication overhead.

[0029] In a possible implementation of the first aspect, the method further includes: sending a bandwidth measurement of the first perception signal.

[0030] The first device may further report to the second device the bandwidth when the first device measures the first perception signal.

[0031] The bandwidth used to measure the first perception signal may be a bandwidth index value. By reporting the bandwidth of the first perception signal measured by the first device (which may be carried simultaneously), the second device can obtain the bandwidth value corresponding to the measurement result of the first perception signal, which helps the second device perform further processing based on multiple measurement results from the same bandwidth, thereby improving the accuracy of the measurement result.

[0032] In the first aspect, in a possible implementation, the bandwidth of the measured first perception signal corresponds to a measurement result of the first perception signal.

[0033] In this way, the second device can determine the bandwidth at which the measurement result of the first perception signal is obtained based on the bandwidth when the first device measures the first perception signal, and then further process multiple measurement results corresponding to the same bandwidth, which is conducive to improving the perception performance and the quality of the perception results.

[0034] In the first aspect, in a possible implementation, the method further includes: sending a preamble code used by the first device to report the capability information.

[0035] The preamble code is the preamble code used by the first device when reporting the capabilities of the first device. The second device will configure the perception signal bandwidth according to the bandwidth capability reported by the first device, and at the same time establish a correspondence between the bandwidth capability and the preamble code of the device with the capability. By reporting the preamble code used by the first device to report capability information, the second device can determine the bandwidth used by the first device based on the correlation between the preamble code and the bandwidth and the preamble code, and then determine the bandwidth value corresponding to the measurement result of the first perception signal, which helps the second device to perform further processing based on multiple measurement results from the same bandwidth, thereby improving the accuracy of the measurement results.

[0036] In the first aspect, in a possible implementation manner, a preamble code used by the first device to report the capability information corresponds to a measurement result of the first perception signal.

[0037] In this way, the second device can determine the bandwidth when the first device measures the first perception signal based on the preamble code, and then determine the bandwidth corresponding to the measurement result of the first perception signal. This is conducive to the second device to further process multiple measurement results from the same bandwidth, thereby improving the accuracy of the measurement results.

[0038] In the first aspect, a possible implementation manner of sending a measurement result of the first perception signal according to the first information includes: the first device sending a bandwidth corresponding to the first perception signal to the second device.

[0039] When the first device sends the measurement result of the first perception signal to the second device, the first device simultaneously reports to the second device the bandwidth when the first device transmits the first perception signal.

[0040] The bandwidth used to transmit the first perception signal may be a bandwidth index value. By including the bandwidth when reporting the measurement result of the first perception signal, the second device can obtain the bandwidth value corresponding to the measurement result of the first perception signal, which helps the second device perform further processing based on multiple measurement results from the same bandwidth, thereby improving the accuracy of the measurement result.

[0041] In the first aspect, a possible implementation manner of sending a measurement result of a first perception signal according to first information includes: a first device sending a preamble code corresponding to the measurement result of the first perception signal.

[0042] This preamble is the preamble used by the first device when reporting its capabilities. The second device configures the perception signal bandwidth based on the bandwidth capability reported by the first device, and establishes a correspondence between the bandwidth capability and the preamble of the device with the capability. By carrying the preamble corresponding to the measurement result of the first perception signal when reporting the measurement result of the first perception signal, the second device can obtain the bandwidth value corresponding to the measurement result of the first perception signal, which helps the second device to perform further processing based on multiple measurement results from the same bandwidth, thereby improving the accuracy of the measurement result.

[0043] In the first aspect, a possible implementation manner of sending the measurement result of the first perception signal includes: sending the measurement result of the first perception signal through a preamble code and a payload; or sending the measurement result of the first perception signal through a preamble code.

[0044] For example, the first device randomly selects a preamble code and its corresponding channel from the preamble code resource pool configured by the second device to send the measurement result of the first perception signal to the second device. The channel carries the payload for carrying the measurement result of the first perception signal, and the preamble code is used to distinguish different first devices.

[0045] For example, when the measurement result of the first perception signal requires less information to indicate, the first device may select a preamble matching its capabilities from a preamble resource pool based on a predefined or preconfigured correspondence between preambles and the measurement result of the first perception signal, and transmit the measurement result of the first perception signal to the second device. The number of preambles matching the measurement result of the first perception signal may be greater than one, so as to reduce conflicts when different first devices select the same preamble.

[0046] If the first device is a non-connected device, the first device can send the measurement result of the first perception signal via a preamble code and a payload, or the first device can send the measurement result of the first perception signal via a preamble code, which can reduce the delay and signaling interaction overhead.

[0047] If the first device is a connected device, the first device can also send the measurement results of the first perception signal to the second device through an uplink or side link. When the first device uses a preamble code + load or a preamble code to send the measurement results of the first perception signal, this can reduce latency and signaling interaction overhead.

[0048] In a possible implementation of the first aspect, the method further includes: sending a third perception signal according to the second parameter.

[0049] In this way, the first device can complete the sensing task of separating sending and receiving.

[0050] In a second aspect, a perception method is provided, which is applied to a second device, including: sending first configuration information and second configuration information, the first configuration information is used to indicate the configuration of a first perception signal, and the second configuration information is used to indicate the transmission configuration of the measurement result of the first perception signal, the first perception signal being a signal sent and received autonomously by the first device; and receiving the measurement result of the first perception signal.

[0051] The execution entity of the solution described in the second aspect may be a second device, a module of the second device (such as a chip system), or a logical node, logic module, or software that can implement all or part of the functions of the second device, without limitation. For ease of description, the following description uses the second device as an example.

[0052] In the above scheme, the second device sends configuration information about the perception signal (including the transmission of the perception signal and the transmission of the measurement results of the perception signal) to the first device. The first device can complete the self-perception task based on the configuration information about the perception signal. In this way, this can support the first device to complete the perception task more independently.

[0053] In addition, there is no need for much interaction between the first device and the second device, thereby reducing the signaling interaction overhead between the first device and the second device for completing the perception task.

[0054] In the second aspect, in a possible implementation manner, the method further includes: sending third configuration information, where the third configuration information is used to indicate a measurement method of the first perception signal.

[0055] When the measurement method of the first perception signal is indicated, the first device may measure the first perception signal according to the indicated measurement method. In this way, the first device may send a measurement result of the first perception signal that meets the requirements of the second device to the second device.

[0056] In a second aspect, a possible implementation manner includes: sending first information, where the first information is used to indicate a constraint condition, and a device that meets the constraint condition performs at least one of perception measurement and capability reporting.

[0057] By limiting the number of devices that meet the constraints to perform at least one of the sensing measurement and capability reporting, interference between different devices can be reduced. In other words, by configuring the constraints, embodiments of the present application can avoid resource conflicts caused by too many devices competing for resources when reporting measurement results, thereby affecting the second device's reception of the sensing signal measurement results.

[0058] In the second aspect, in a possible implementation, the method further includes: sending first information, where the first information is used to request feedback capability information, where the capability information is used to indicate the capability of the first device to associate with the first perception signal; and receiving the capability information.

[0059] By acquiring the capability information of the first device, the second device can configure the transmission, measurement, and reporting of the perception signal for the first device according to the capability of the first device, which can enable the first device to better complete the perception task.

[0060] Specifically, the capability information of the first device can be used by the second device to configure corresponding first configuration information and second configuration information for the first device according to the capability of the first device, so that the first device can better complete the perception task within its capability.

[0061] In the second aspect, a possible implementation method is that the receiving capability information includes: receiving the capability information through a preamble and a payload; or receiving the capability information through a preamble.

[0062] In the second aspect, a possible implementation manner is that receiving the measurement result of the first perception signal includes: receiving the measurement result of the first perception signal through a preamble code and a payload; or receiving the measurement result of the first perception signal through a preamble code.

[0063] In this way, the delay and signaling interaction overhead can be reduced.

[0064] In the second aspect, in a possible implementation, the method further includes: receiving a bandwidth of the first perception signal measured by the first device.

[0065] When the first device sends the measurement result of the first perception signal to the second device, the first device may further report to the second device the bandwidth when the first device measures the first perception signal.

[0066] The bandwidth used to measure the first perception signal may be a bandwidth index value. By including the bandwidth when reporting the measurement result of the first perception signal (which may be carried simultaneously), the second device can obtain the bandwidth value corresponding to the measurement result of the first perception signal, which helps the second device perform further processing based on multiple measurement results from the same bandwidth, thereby improving the accuracy of the measurement result.

[0067] In the second aspect, in a possible implementation, the bandwidth of the first perception signal measured by the first device corresponds to a measurement result of the first perception signal.

[0068] In this way, the second device can determine the bandwidth under which the measurement result of the first perception signal is obtained based on the bandwidth when the first device measures the first perception signal.

[0069] Furthermore, the second device can further process multiple measurement results from the same bandwidth, which is beneficial to improving perception performance and improving the quality of perception results.

[0070] In the second aspect, in a possible implementation, the method further includes: receiving a preamble code used by the first device to report the capability information.

[0071] This preamble is the preamble used by the first device when reporting its capabilities. The second device configures the perception signal bandwidth based on the bandwidth capability reported by the first device, and establishes a correspondence between the bandwidth capability and the preamble of the device with the capability. By carrying the preamble corresponding to the measurement result of the first perception signal when reporting the measurement result of the first perception signal, the second device can obtain the bandwidth value corresponding to the measurement result of the first perception signal, which helps the second device to perform further processing based on multiple measurement results from the same bandwidth, thereby improving the accuracy of the measurement result.

[0072] In the second aspect, in a possible implementation manner, a preamble code used by the first device to report the capability information corresponds to a measurement result of the first perception signal.

[0073] In the second aspect, in a possible implementation, the second device receives a bandwidth corresponding to the first perception signal from the first device.

[0074] When the first device sends the measurement result of the first perception signal to the second device, the first device simultaneously reports to the second device the bandwidth when the first device transmits the first perception signal.

[0075] The bandwidth used to transmit the first perception signal may be a bandwidth index value. By including the bandwidth when reporting the measurement result of the first perception signal, the second device can obtain the bandwidth value corresponding to the measurement result of the first perception signal, which helps the second device perform further processing based on multiple measurement results from the same bandwidth, thereby improving the accuracy of the measurement result.

[0076] In the second aspect, in a possible implementation, the second device receives a preamble corresponding to a measurement result of the first perception signal from the first device.

[0077] This preamble is the preamble used by the first device when reporting its capabilities. The second device configures the perception signal bandwidth based on the bandwidth capability reported by the first device, and establishes a correspondence between the bandwidth capability and the preamble of the device with the capability. By carrying the preamble corresponding to the measurement result of the first perception signal when reporting the measurement result of the first perception signal, the second device can obtain the bandwidth value corresponding to the measurement result of the first perception signal, which helps the second device to perform further processing based on multiple measurement results from the same bandwidth, thereby improving the accuracy of the measurement result.

[0078] In combination with the solution described in any one of the first and second aspects, in a possible implementation manner, a measurement method of the first perception signal is predefined.

[0079] When the measurement method of the first perception signal is predefined, the first device can measure the first perception signal according to the predefined measurement method, which can reduce signaling interaction overhead.

[0080] In combination with the solutions described in any one of the first and second aspects, in one possible implementation, the measurement method of the first perception signal includes at least one of the following: a round-trip time measurement method, an angle measurement method, and a Doppler measurement method.

[0081] In this way, the embodiments of the present application support multiple measurement methods to complete the perception task.

[0082] In combination with the solution described in any one of the first and second aspects, in one possible implementation, the measurement result of the first perception signal includes at least one of the following: an identifier of the transmission resource, a received signal strength, a received signal strength of each multipath component, a time difference between a sending time and a receiving time, a receiving timestamp, and a difference between the receiving timestamp and the receiving timestamp of the second perception signal, where the second perception signal is a signal sent by the second device to the first device.

[0083] In this way, the second device can obtain round-trip time information about the perception target.

[0084] In combination with the scheme described in any one of the first and second aspects, in one possible implementation, the measurement result of the first perception signal includes at least one of the following: an identifier of the transmission resource, a transmit beam, a receive beam, a received signal strength, a received signal strength of each multipath component, and a receive timestamp.

[0085] In this way, the second device can obtain the position information about the perception target.

[0086] In combination with the solution described in any one of the first and second aspects, in one possible implementation, the measurement result of the first perception signal includes at least one of the following: an identifier of the transmission resource, a Doppler shift value obtained based on the first perception signal, a speed value of the perception target obtained based on the first perception signal, and a receiving timestamp.

[0087] In this way, the second device can obtain Doppler measurement information about the perceived target.

[0088] In combination with the scheme described in any one of the first and second aspects, a possible implementation method is that the constraint condition includes at least one of the following: received signal strength, bandwidth capability, geographical location range, beam range, type of duplex capability, measurement method, self-sensing transceiver beam reciprocity, maximum number of antenna ports, speed range and device type.

[0089] Through one or more of the parameters listed above, the embodiments of the present application can screen the devices participating in the perception measurement and capability reporting, and only the devices that meet the constraint conditions can perform parameter perception measurement and capability reporting. This can avoid resource conflicts caused by too many devices competing for resources when reporting measurement results, thereby affecting the second device's reception of the measurement results of the perception signal.

[0090] In combination with the solutions described in any one of the first and second aspects, in one possible implementation, the capability information includes at least one of the following: bandwidth capability, type of duplex capability, measurement method, beam reciprocity capability, and maximum number of antenna ports.

[0091] For example, by reporting bandwidth capabilities, the second device can determine the bandwidth supported by the first device for perception signal transmission. The second device can configure the configuration information about the perception signal based on the bandwidth supported by the first device, so that the first device can better complete the perception task within its capabilities.

[0092] For example, by reporting the duplex capability of the first device, the second device can specifically configure the perception receiving window time range of the first device, and at the same time, it helps the second device to determine the minimum perceptible measurement distance corresponding to different duplex modes of the first device.

[0093] For example, by reporting the measurement method supported by the first device, the second device can configure the perception measurement of the perception signal in combination with the perception requirements and the measurement method supported by the first device. For example, if the first device supports an angle-based measurement method, and the angle-based method is not sensitive to bandwidth, the second device can configure a relatively small perception signal bandwidth to the first device for angle measurement reporting to meet the perception requirements.

[0094] For example, by reporting the beam reciprocity capability information of the first device, if the first device supports beam reciprocity, the second device can simultaneously complete the configuration of the receiving beam or the transmitting beam by only configuring the transmitting beam or the receiving beam of the first device, that is, configuring the transmitting beam and the receiving beam pair of the first device at the same time, which helps to reduce signaling overhead. Then, the first device measures and reports the perception signal transmitted based on the transmitting and receiving beam pair.

[0095] For example, by reporting the maximum antenna port supported by the first device, the second device can configure the corresponding time-frequency transmission resources of the perception signal to perform perception measurement reporting.

[0096] In combination with the solutions described in any one of the first and second aspects, in one possible implementation, the first configuration information is associated with the capability of the first device, and / or the second configuration information is associated with the capability of the first device.

[0097] In this way, the first device can better complete the perception task within its capabilities.

[0098] In combination with the solutions described in any one of the first and second aspects, a possible implementation method is that the first configuration information is associated with the capabilities of the first device, including: the first configuration information is configured according to the capabilities of the first device, or the capabilities pre-associated with the first configuration information are the capabilities of the first device.

[0099] In this way, the first device can better complete the perception task within its capabilities.

[0100] In combination with the solutions described in any one of the first and second aspects, a possible implementation method is that the second configuration information is associated with the capabilities of the first device, including: the second configuration information is configured according to the capabilities of the first device, or the capabilities pre-associated with the second configuration information are the capabilities of the first device.

[0101] In this way, the first device can better complete the perception task within its capabilities.

[0102] In combination with the scheme described in any one of the first and second aspects, a possible implementation method is that the first configuration information is used to configure the first parameter, and the first parameter includes at least one of the following: subcarrier spacing, cyclic prefix length, transmission time, receiving window time, bandwidth, frequency starting position, sequence, transmission beam and receiving beam; or, the first parameter includes at least one of the following: subcarrier spacing, cyclic prefix length, transmission time, receiving window time, frequency starting position, sequence, transmission beam and receiving beam.

[0103] In this way, the first device can send and receive the first perception signal according to some or all of the parameters listed above.

[0104] In combination with the scheme described in any one of the first and second aspects, a possible implementation method is that the first information also includes fourth configuration information, and the fourth configuration information is used to configure the transmission of a third perception signal. The third perception signal is a perception signal sent by the first device to the second device. The fourth configuration information is used to configure the second parameter, and the second parameter is used for the transmission of the third perception signal. The first parameter is associated with the second parameter.

[0105] It should be noted that the first parameter and the second parameter are associated, and the first device can determine the first parameter based on the second parameter and the association between the second parameter and the first parameter. For example, the subcarrier spacing in the first parameter can be determined based on the subcarrier spacing in the second parameter. Exemplarily, the second device indicates to the first device the subcarrier spacing in the first parameter and the multiple or factor relationship between the subcarrier spacing in the second parameter to indicate the subcarrier spacing in the first parameter. The first device can determine the subcarrier spacing in the first parameter based on the subcarrier spacing in the second parameter and the multiple or factor relationship. In this way, the signaling overhead for indicating the first parameter can be reduced.

[0106] In combination with the scheme described in any one of the first and second aspects, a possible implementation method is that the second parameter includes at least one of the following: subcarrier spacing, cyclic prefix length, transmission time, receiving window time, bandwidth, frequency starting position, sequence, transmission beam and receiving beam.

[0107] In this way, the first device can send the third perception signal according to some or all of the parameters listed above.

[0108] In combination with the solutions described in any one of the first and second aspects, in one possible implementation, the first parameter includes bandwidth, and the bandwidth in the first parameter is determined based on the bandwidth in the second parameter.

[0109] In this way, the second device can indicate the bandwidth in the first parameter to the first device with a smaller signaling overhead. For example, the second device indicates the bandwidth in the first parameter to the first device by using an offset between the bandwidth in the first parameter and the bandwidth in the second parameter. The first device can determine the bandwidth in the first parameter based on the bandwidth in the second parameter and the offset. In this way, this can reduce the signaling interaction overhead.

[0110] In combination with the solutions described in any one of the first and second aspects, a possible implementation method is that the first device is a device in an inactive state, or the first device is a low-power device, or the first device is a device in an idle state; or the first device is a device in a connected state.

[0111] In this way, the embodiments of the present application can support devices in different states to complete perception tasks.

[0112] By enabling devices in different states to participate in collaborative sensing tasks, the available range of collaborative sensing is greatly improved, the geographical space that can be sensed is expanded, and the quality of perception is improved.

[0113] In combination with the solutions described in any one of the first and second aspects, a possible implementation method is that the first configuration information and / or the second configuration information are carried in the system information, or the first configuration information and / or the second configuration information are carried in the capability reporting response information.

[0114] When the first configuration information and / or the second configuration information is carried in the system information, this allows devices in various RRC states to receive the information, so that devices that meet the constraint conditions can report capabilities or perception measurements according to the indication information;

[0115] When the first configuration information and / or the second configuration information is carried in the capability reporting response information, the device that meets the constraint conditions for capability reporting, rather than other devices, reads the response information to perform further perception measurement reporting.

[0116] In combination with the solutions described in any one of the first and second aspects, in one possible implementation, the first configuration information and / or the second configuration information is carried in the capability reporting response information, and the second information is carried in the system information.

[0117] When the first configuration information and / or the second configuration information is carried in the capability reporting response information, the device that meets the constraint conditions for capability reporting, rather than other devices, reads the response information to perform further perception measurement reporting.

[0118] When the second information is carried in the system information, the capability request information can be broadcast to devices in different RRC states, enabling as many devices as possible that meet the constraints to report their capabilities; then these devices that report capabilities receive the capability reporting response information and perform perception measurement reporting based on the capability reporting response information.

[0119] By carrying the second information in the system information and carrying the first configuration information and / or the second configuration information in the capability reporting response information, this may enable a random perception reporting process to perform perception measurement reporting or a random access process to perform perception measurement reporting without the need for the device to perform perception measurement reporting by establishing an RRC connection, thereby reducing the interaction process, reducing signaling overhead, and reducing latency.

[0145] The technical solution in this application will be described below with reference to the accompanying drawings.

[0146] In order to facilitate understanding of the embodiments of the present application, the following points are first explained.

[0147] 1. Unless otherwise specified, “plurality” means two or more.

[0148] 2. Unless otherwise specified or there is no logical conflict, the terms and / or descriptions between different embodiments of this application are consistent and can be referenced by each other. The technical features in different embodiments can be combined to form new embodiments based on their internal logical relationships.

[0149] 3. The various numerical numbers involved in this application are only used for the convenience of description and are not used to limit the scope of protection of this application. The size of the serial numbers involved in this application does not mean the order of execution. The order of execution of each process should be determined by its function and internal logic. For example, the terms "first", "second", "third", "fourth" and other various terminology labels (if any) in the specification and claims and drawings of this application are used to distinguish similar objects, and are not necessarily used to describe a specific order or sequence. Among them, the data used in this way can be interchangeable where appropriate, so that the embodiments described here can be implemented in an order other than what is illustrated or described here.

[0150] At the same time, any embodiment or design described in this application as "exemplary" or "for example" should not be interpreted as being more preferred or more advantageous than other embodiments or designs. Specifically, the use of words such as "exemplary" or "for example" is intended to present the relevant concepts in a concrete manner to facilitate understanding.

[0151] 4. The terms "comprise" and "have" and any variations thereof are intended to cover non-exclusive inclusions. For example, a process, method, system, product or apparatus that includes a series of steps or units is not necessarily limited to those steps or units explicitly listed, but may include other steps or units not explicitly listed or inherent to such process, method, product or apparatus.

[0152] 5. In this application, "used to indicate" can be understood as "enabling," and "enabling" can include direct enabling and indirect enabling. When describing that certain information is used to enable A, it can include that the information directly enables A or indirectly enables A, and does not necessarily mean that the information contains A.

[0153] The information enabled by the information is called information to be enabled. In the specific implementation process, there are many ways to enable the enabled information, such as but not limited to, directly enabling the information to be enabled, such as the information to be enabled itself or the index of the information to be enabled. The information to be enabled can also be indirectly enabled by enabling other information, wherein there is an association between the other information and the information to be enabled. It is also possible to enable only a part of the information to be enabled, while the other parts of the information to be enabled are known or agreed in advance. For example, it is also possible to enable specific information with the help of the arrangement order of each piece of information agreed in advance (such as specified in the protocol), thereby reducing the enabling overhead to a certain extent. At the same time, it is also possible to identify the common parts of each piece of information and enable them uniformly to reduce the enabling overhead caused by enabling the same information separately.

[0154] 6. In this application, "pre-configuration" may include pre-definition, such as protocol definition. "Pre-definition" may be implemented by pre-storing corresponding codes, tables, or other methods that can be used to indicate relevant information in a device (e.g., including each network element). This application does not limit the specific implementation method.

[0155] 7. "Storage" or "saving" as used in this application may refer to storage in one or more memories. The one or more memories may be provided separately or integrated into an encoder or decoder, a processor, or a communication device. The one or more memories may also be provided in part separately and in part integrated into a decoder, processor, or communication device. The type of memory may be any form of storage medium and is not limited thereto.

[0156] 8. The “protocol” referred to in this application may refer to a standard protocol in the field of communications, such as the fourth generation (4G) th generation, 4G) network, fifth generation (5 th generation, 5G) network protocol, NR protocol, 5.5G network protocol, sixth generation (6 th generation, 6G) network protocols and related protocols used in future communication systems, which are not limited in this application.

[0157] 9. The arrows or boxes indicated by dotted lines in the schematic diagrams in the accompanying drawings of this application specification represent optional steps or optional modules.

[0158] 10. Unless otherwise specified, “ / ” indicates that the objects associated with each other are in an “or” relationship. For example, A / B can mean A or B. “And / or” in this application is only a description of the association relationship between the associated objects, indicating that there can be three relationships. For example, A and / or B can mean: A exists alone, A and B exist at the same time, and B exists alone. A and B can be singular or plural.

[0159] 11. In this application, "indication" may include direct indication, indirect indication, explicit indication, and implicit indication. When describing a certain indication information as indicating A, it can be understood that the indication information carries A, directly indicates A, or indirectly indicates A.

[0160] In this application, the information indicated by the indication information is referred to as the information to be indicated. In the specific implementation process, there are many ways to indicate the information to be indicated, such as but not limited to, the information to be indicated can be directly indicated, such as the information to be indicated itself or the index of the information to be indicated. The information to be indicated can also be indirectly indicated by indicating other information, wherein there is an association between the other information and the information to be indicated. It is also possible to indicate only a part of the information to be indicated, while the other parts of the information to be indicated are known or agreed in advance. For example, the indication of specific information can also be achieved with the help of the arrangement order of each information agreed in advance (for example, stipulated by the protocol), thereby reducing the indication overhead to a certain extent. In addition, the information to be indicated can be sent together as a whole, or it can be divided into multiple sub-information and sent separately, and the sending period and / or sending time of these sub-information can be the same or different.

[0161] 12. In this application, "sending" and "receiving" indicate the direction of signal transmission. For example, "sending information to XX" can be understood as the destination of the information being XX, which can include direct sending through the air interface, as well as indirect sending through the air interface by other units or modules. "Receiving information from YY" can be understood as the source of the information being YY, which can include direct receiving from YY through the air interface, as well as indirect receiving from YY through the air interface from other units or modules. "Sending" can also be understood as the "output" of the chip interface, and "receiving" can also be understood as the "input" of the chip interface. In other words, sending and receiving can be performed between devices, for example, between a network device and a terminal device, or can be performed within a device, for example, sending or receiving between components, modules, chips, software modules, or hardware modules within the device through a bus, trace, or interface.

[0162] First, a communication system to which the embodiments of the present application are applicable is described.

The terminal device can be a terminal in any of the above scenarios, such as an MTC terminal, an IoT terminal, etc. The terminal device can be a 3GPP (3rd Generation Partnership Project) terminal. rdThe present invention relates to user equipment (UE), terminal, fixed device, mobile station device or mobile device, subscriber unit, handheld device, vehicle-mounted device, wearable device, cellular phone, smart phone, SIP phone, wireless data card, personal digital assistant (PDA), computer, tablet computer, notebook computer, wireless modem, handheld device, laptop computer, computer with wireless transceiver function, smart book, vehicle, satellite, global positioning system (GPS) device, target tracking device, aircraft (such as drone, helicopter, multi-copter, quadcopter, or airplane), ship, remote control device, smart home device, industrial equipment, or device built into the above devices (such as communication module, modem or chip in the above devices), or other processing devices connected to the wireless modem. For the convenience of description, the terminal device will be described below by taking the terminal or UE as an example.

[0165] In some scenarios, the terminal device can also be used to act as a base station. For example, the terminal device can act as a scheduling entity, which provides sidelink signals between UEs in scenarios such as V2X, D2D, or P2P.

[0166] In the embodiments of the present application, the device for implementing the function of the terminal device can be the terminal device, or it can be a device that can support the terminal device to implement the function, such as a chip system or chip, which can be installed in the terminal device. In the embodiments of the present application, the chip system can be composed of a chip, or it can include a chip and other discrete devices.

[0167] The network device in the embodiments of the present application may be a device for communicating with a terminal device, and may also be referred to as an access network device or a radio access network device. For example, the network device may be a base station. The network device in the embodiments of the present application may refer to a radio access network (RAN) node (or device) that connects a terminal device to a wireless network. Base station can broadly cover various names as follows, or replace the following names, such as: NodeB, evolved NodeB (eNB), next generation NodeB (gNB), relay station, access point, transmission point (TRP), transmission point (TP), master station, auxiliary station, multi-standard wireless (motor slide retainer, MSR) node, home base station, network controller, access node, wireless node, access point (AP), transmission node, transceiver node, baseband unit (BBU), remote radio unit (RRU), active antenna unit (AAU), remote radio head (RRH), central unit (CU), distributed unit (DU), positioning node, etc. The base station can be a macro base station, a micro base station, a relay node, a donor node or the like, or a combination thereof. The base station can also refer to a communication module, modem or chip used to be set in the aforementioned device or apparatus. The base station can also be a mobile switching center and a device that performs base station functions in D2D, V2X, and M2M communications, a network-side device in a 6G network, or a device that performs base station functions in future communication systems. The base station can support networks with the same or different access technologies. The embodiments of this application do not limit the specific technology and specific device form used by the network equipment.

[0168] Base stations can be fixed or mobile. For example, a helicopter or drone can be configured to act as a mobile base station, and one or more cells can move based on the location of the mobile base station. In other examples, a helicopter or drone can be configured to act as a device that communicates with another base station.

[0169] In the embodiments of the present application, the device for implementing the function of the network device can be a terminal device, or a device that can support the network device to implement the function, such as a chip system or chip, which can be installed in the network device. In the embodiments of the present application, the chip system can be composed of a chip, or it can include a chip and other discrete devices.

[0170] The network equipment and terminal devices can be deployed on land, including indoors or outdoors, handheld or vehicle-mounted; they can also be deployed on water; they can also be deployed in the air on aircraft, balloons, and satellites. The embodiments of this application do not limit the scenarios in which the network equipment and terminal devices are located.

[0171] First, a brief introduction to the network architecture applicable to the embodiments of the present application is given.

[0172] Figure 1 is a schematic diagram of a communication system applicable to an embodiment of the present application. As shown in Figure 1, the communication system includes a radio access network (RAN) 100 and a core network (CN) 200. The RAN 100 includes at least one RAN node (such as 110a and 110b, collectively referred to as 110) and at least one terminal device (such as 120a-120j, collectively referred to as 120). The RAN 100 may also include other RAN nodes, such as wireless relay devices and / or wireless backhaul devices (not shown in Figure 1). The terminal device 120 is connected to the RAN node 110 wirelessly. The RAN node 110 is connected to the core network 200 wirelessly or by wire. The core network devices in the core network 200 and the RAN node 110 in the RAN 100 can be different physical devices, or they can be the same physical device that integrates the core network logical functions and the radio access network logical functions.

[0173] The RAN 100 may be a 3GPP-related cellular system, such as a 4G or 5G mobile communication system, or a future-oriented evolutionary system (such as a 6G mobile communication system). The RAN 100 may also be an open access network (O-RAN or ORAN), a cloud RAN (CRAN), or a wireless fidelity (WiFi) system. The RAN 100 may also be a communication system that integrates two or more of the above systems.

[0174] RAN node 110, sometimes also referred to as access network equipment, RAN entity, or access node, constitutes part of a communication system and facilitates wireless access for terminal devices. Multiple RAN nodes 110 in the communication system can be of the same type or different types. In some scenarios, the roles of RAN node 110 and terminal device 120 are relative. For example, network element 120i can be a helicopter or drone configured as a mobile base station. For terminal device 120j accessing RAN 100 via network element 120i, network element 120i is a base station; however, for base station 110a, network element 120i is a terminal device. RAN node 110 and terminal 120 are sometimes referred to as communication devices. For example, network elements 110a and 110b can be understood as communication devices with base station functionality, and network elements 120a-120j can be understood as communication devices with terminal functionality.

[0175] In one possible scenario, a RAN node may be a base station (BS), an eNodeB, an access point (AP), a Transmitter Relay (TRP), a gNB, a next-generation base station in a 6G mobile communication system, a base station in a future mobile communication system, or an access node in a WiFi system. A RAN node may be a macro base station (such as 110a in Figure 1 ), a micro base station or an indoor station (such as 110b in Figure 1 ), a relay node or a donor node, or a wireless controller in a CRAN scenario.

[0176] Optionally, the RAN node may also be a server, a wearable device, a vehicle or an on-board device, etc. For example, the access network device in the V2X technology may be a road-side unit (RSU) or a base station. All or part of the functions of the RAN node in this application may also be implemented by software functions running on hardware, or by virtualization functions instantiated on a platform (such as a cloud platform). The RAN node in this application may also be a logical node, a logical module or software that can implement all or part of the functions of the RAN node.

[0177] In another possible scenario, multiple RAN nodes collaborate to assist terminal devices in achieving wireless access, and different RAN nodes respectively implement part of the functions of the base station. For example, the RAN node can be a centralized unit (CU), a distributed unit (DU), a CU-control plane (CP), a CU-user plane (UP), or a radio unit (RU). The CU and DU can be set up separately, or they can be included in the same network element, such as a baseband unit (BBU). The RU can be included in a radio frequency device or radio frequency unit, such as a remote radio unit (RRU), an active antenna unit (AAU), or a remote radio head (RRH).

[0178] In different communication systems, CU (or CU-CP and CU-UP), DU or RU may also have different names, but those skilled in the art can understand their meanings. For example, in the ORAN system, CU may also be called O-CU (Open CU), DU may also be called O-DU, CU-CP may also be called O-CU-CP, CU-UP may also be called O-CU-UP, and RU may also be called O-RU. For the convenience of description, this application uses CU, CU-CP, CU-UP, DU and RU as examples for description. Any unit of CU (or CU-CP, CU-UP), DU and RU in this application can be implemented by a software module, a hardware module, or a combination of a software module and a hardware module.

[0179] It should be understood that the number of each device in the above-mentioned communication system is only for illustration and is not limited thereto. In actual applications, the communication system may further include more terminal devices, more RAN devices, and other devices.

[0180] It should be understood that Figure 1 is a simplified schematic diagram for ease of understanding, and the communication system may also include a larger number of network devices or terminal devices. In addition, the embodiments of the present application may be applicable to any communication scenario in which a transmitting device and a receiving device communicate with each other.

[0181] To facilitate understanding of the embodiments of the present application, the following is a brief explanation of the terms involved in the embodiments of the present application.

[0182] 1. Perception: In the field of communication and perception fusion, perception refers to acquiring environmental information through a perception network, such as target positioning, imaging, detection, and tracking. This perception information can be used to optimize and enhance communication systems, such as avoiding obstacles and improving communication quality. Perception can also be used for channel modeling and signal analysis in wireless communication systems, thereby better understanding and optimizing communication performance.

[0183] 2. Self-perception: In the embodiments of the present application, self-perception refers to the ability to measure the perception of a perceived target by receiving a perception signal emitted by the device itself. For example, in wireless communications, self-perception can include the perception of wireless channels, the perception of transmit power, the perception of signal quality, and the like. For example, a transmitter transmits a perception signal, which is then reflected by a perceived target and received by the transmitter. The transmitter can then determine the distance to the perceived target based on the transmission and reception times of the perception signal. Self-perception technology has applications in many fields, such as intelligent transportation, smart cities, and smart homes.

[0184] 3. Perception with separated transmit and receive: In the embodiment of the present application, separated transmit and receive perception refers to performing the two functions of receiving and sending independently. Separate transmit and receive perception can achieve better signal reception and transmission effects, and can also reduce system complexity and improve system stability. For example, a separate transmit and receive perception system includes two parts: a transmitter and a receiver. The transmitter is responsible for transmitting the perception signal, which is received by the receiver after being reflected by the perception target. The receiver processes the perception signal to obtain information about the perception target. Separate transmit and receive perception technology has applications in many fields, such as wireless communications, satellite communications, radar, etc. This technology can improve the transmission efficiency and reliability of the communication system, and can also reduce the complexity and cost of the system.

[0185] 4. Sensing management function (SEMF): In the field of communications, SEMF is a sensing management functional block used to manage communication equipment. Alternatively, in the field of communication converged perception, SEMF is a sensing management functional block used to manage communication equipment or communication converged perception equipment. The role of SEMF is to collect information from other functional blocks or other entities or other devices, for example, including: sensing requirements, sensing measurement results, sensing calculation results, sensing capability feedback, sensing assistance requests, sensing resource allocation feedback, and perform corresponding management operations, including issuing commands to each functional block or entity or device, including: sensing capability requests, sensing assistance responses, sensing signal configuration, sensing measurement reporting configuration, sensing result calculation, target classification, target identification, etc., and interacting with other functional entities or other devices through sensing protocols or signaling channels or data channels. The sensing management function can be located in the core network, access network or terminal equipment.

[0186] Positioning is one of the capabilities of perception. 5G NR has standardized air interface positioning, and the core network supports positioning management functions for resource coordination and scheduling related to positioning, determination of target location, and speed estimation and measurement accuracy of measurement signals. The positioning management function is located in the core network and can respond to positioning requirements from the outside or the UE. In addition, the positioning of a UE in an RRC connected state or an RRC inactive state (inactive) requires the participation of the UE, such as the participation of the UE in signal reception and / or transmission, for example, the UE measures and reports the PRS sent by the base station, or the UE sends a sounding reference signal (SRS) for measurement by the base station.

[0187] Currently, existing perception processes (such as positioning) require extensive interaction between network devices and terminal devices. For example, the network device sends a Positioning Reference Signal (PRS) to the terminal device, the terminal device measures the PRS, and reports the PRS measurement results to the network device. However, these processes do not allow terminal devices to independently complete perception tasks.

[0188] In view of this, the present application provides a perception method, a communication device and a system that can support terminal devices to complete perception tasks relatively independently (or what can be called self-perception tasks).

[0189] The following describes the sensing method, communication device, and system according to the embodiments of the present application in conjunction with the accompanying drawings.

[0190] For ease of understanding and explanation, the following describes the perception method of the embodiment of the present application by taking the interaction between the first device and the second device as an example, but this should not constitute any limitation on the execution subject of the perception method of the embodiment of the present application. For example, the method performed by the first device can also be performed by a module of the first device (such as a circuit, chip or chip system, etc.), and can also be implemented by a logical node, logical module or software that can realize all or part of the function of the first device. The method performed by the second device can also be performed by a module of the second device (such as a circuit, chip or chip system, etc.), and can also be implemented by a logical node, logical module or software that can realize all or part of the function of the second device.

[0191] The aforementioned apparatus may also be a device, a communication device, a communication device, a component or chip in a device, etc. For example, the first apparatus may be a first device, a first communication device, a first communication device, a first component, or a first chip, etc., and the second apparatus may be a second device, a second communication device, a second communication device, a second component, or a second chip, etc.

[0192] The first device may be a terminal device, and the second device may be a terminal device or a network device. When both the first device and the second device are terminal devices, the communication between the first device and the second device is side-link (SL) communication. When the first device is a terminal device and the second device is a network device, the communication between the first device and the second device is air interface communication or Uu interface communication.

[0193] In summary, the following describes the perception method of an embodiment of the present application using the first device and the second device as examples, but does not limit the devices or apparatuses (such as terminal devices or network devices, etc.) to which the first device and the second device correspond respectively.

[0194] FIG2 is a schematic diagram of an interactive process of a perception method according to an embodiment of the present application. As shown in FIG2 , the method includes:

[0195] S201. The second device sends first configuration information and second configuration information to the first device.

[0196] Correspondingly, the first device receives the first configuration information and the second configuration information.

[0197] The first configuration information is used to indicate a configuration of the first perception signal, and the second configuration information is used to indicate a transmission configuration of a measurement result of the first perception signal.

[0198] The first sensing signal is a signal that the first device sends and receives. For example, the first device sends the first sensing signal to a sensing target, the sensing target reflects the first sensing signal, and the first device receives the first sensing signal reflected from the sensing target. In this way, by sending the first sensing signal to the sensing target and receiving the first sensing signal reflected from the sensing target, the first device can obtain information about the sensing target, such as the sensing target's movement speed or direction.

[0199] The first configuration information and the second configuration information may be carried in the same information or in different information respectively, without limitation.

[0200] In one possible implementation, the first configuration information is used to indicate the configuration of the first perception signal and may be:

[0201] The first configuration information is used to configure transmission of the first perception signal. For example, the first configuration information is used to configure sending and receiving of the first perception signal. The first device may send and receive the first perception signal according to the first configuration information; or

[0202] The first configuration information is used to configure the communication of the first perception signal. The first device can communicate the first perception signal according to the first configuration information. For example, the first device can send the first perception signal to the perception target according to the first configuration information, and receive the signal obtained after the perception target reflects the first perception signal according to the first configuration information.

[0203] In summary, the first device can complete the autonomous transmission and reception of the first perception signal according to the first configuration information.

[0204] In another possible implementation, the second configuration information is used to indicate a transmission configuration of the measurement result of the first perception signal, and may be:

[0205] The second configuration information is used to configure the transmission of the measurement result of the first perception signal. For example, the second configuration information is used to configure the sending of the measurement result of the first perception signal. The first device may report or send the measurement result of the first perception signal according to the second configuration information. For example, the first device may send, report, or feedback the measurement result of the first perception signal to the second device according to the second configuration information; or

[0206] The second configuration information is used to configure reporting of the measurement result of the first perception signal. For example, the first device may report the measurement result of the first perception signal according to the second configuration information; or,

[0207] The second configuration information is used to configure the communication configuration of the measurement result of the first perception signal. For example, the first device can complete the communication, reporting, feedback, or interaction of the measurement result of the first perception signal with the second device according to the second configuration information; or,

[0208] The second configuration information can also be used to configure the feedback resources corresponding to the preamble. The second configuration information may include the configuration of the feedback resources corresponding to one or more preambles. For example, the second configuration information includes multiple preambles and the resource configuration of the physical uplink shared channel (PUSCH) of each of the multiple preambles. After the first device obtains the configuration information, it can find the feedback resource corresponding to the reported measurement result based on the preamble used by itself.

[0209] The second configuration information also includes capability response information for more than one first device, rather than notifying each first device individually. This reduces signaling overhead. A first device can obtain feedback resources based on the preamble used when reporting its capabilities, rather than blindly selecting from a resource pool. This reduces the probability of resource collision and improves the reliability of measurement result reporting.

[0210] In summary, the first device can complete the reporting or feedback of the measurement results of the first perception signal according to the second configuration information.

[0211] In one possible implementation, the second configuration information may include resource configuration information for transmitting the measurement result of the first perception signal. For example, the resource configuration information may include one or more of a time-frequency resource, a sequence resource, and a modulation and coding scheme (MCS) indication for transmitting the measurement result of the first perception signal. In this way, the first apparatus may complete the transmission or reporting of the measurement result of the first perception signal according to the second configuration information.

[0212] The first configuration information and the second configuration information may be configured by the second device (or other devices, such as a SEMF located in the core network, not limited thereto) for the first device. For example, in a unicast scenario, the second device communicates with the first device, and the second device configures the configuration information for the first device to complete the perception task, such as the first configuration information and the second configuration information; in a broadcast scenario, the second device communicates with multiple first devices, and the second device configures corresponding configuration information for some or all of the multiple first devices to complete the perception task, such as configuring corresponding first configuration information and second configuration information for some or all of the first devices, and the some or all of the first devices can complete the perception task according to their respective first configuration information and second configuration information; for another example, in a multicast scenario or a groupcast scenario, the second device communicates with the first device in a device group, and the second device configures corresponding configuration information for some or all of the first devices in the device group to complete the perception task, and the some or all of the first devices in the device group can complete the perception task according to the corresponding configuration information.

[0213] For ease of description, the following does not distinguish whether the communication scenario between the first device and the second device is a unicast scenario, a broadcast scenario, or a multicast scenario. The first device can obtain the corresponding first configuration information and second configuration information, thereby completing the perception task.

[0214] In one possible implementation, the measurement result of the first perception signal is associated with a method (or manner) for measuring the first perception signal by the first apparatus, as described below:

[0215] Exemplarily, the first device measures the first perception signal using a first measurement method to obtain a measurement result corresponding to the first measurement method;

[0216] Exemplarily, the first device measures the first perception signal using the second measurement method to obtain a measurement result corresponding to the second measurement method;

[0217] Exemplarily, the first device uses the third measurement method to measure the first perception signal and obtains a measurement result corresponding to the third measurement method.

[0218] For example, the first measurement method is a round trip time (RTT) measurement method:

[0219] The first device detects the reflected first perception signal on the perception receiving window. When the received signal strength of the reflected first perception signal is higher than a threshold (not limited to a specific value), the first device can determine the time difference between the sending time and the receiving time of the first perception signal, thereby obtaining the RTT value of the first perception signal.

[0220] For example, the second measurement method is an angle measurement method:

[0221] In order to perceive a specific direction range, it is necessary to configure the perception angle, as well as the angle of the transmit beam and the angle of the receive beam. Considering the reciprocity of the transmit beam and the receive beam, the receive beam of the first perception signal can be determined by only configuring the transmit beam of the first perception signal. The first device detects the reflected first perception signal on the perception receiving window. When the received signal strength of the reflected first perception signal is higher than a threshold (the specific value of the threshold is not limited and can be configured based on the situation), it indicates that there is a target in the direction of the receive beam.

[0222] Accordingly, the first device can determine the angle of the received beam of the first sensing signal, thereby determining the approximate direction of the target. Signal beam reciprocity can also be referred to as a spatial relation between signal beams or a spatial relation between signals. The spatial relation of a beam can be determined based on other beams, or the spatial relation of a signal can be determined based on other signals. For example, beam A and beam B have beam reciprocity, indicating that the spatial relation of beam A can be determined based on beam B (e.g., beam B's beam information). For example, if signals A and B have a spatial relation, it can also be said that the spatial relation of signal B can be obtained through signal A.

[0223] The reciprocity of the transmitting and receiving beams in the embodiments of the present application, or the determination of one beam by another beam, or the determination of one signal spatial relationship by another signal, or the determination of one signal spatial relationship by another signal spatial relationship, or the determination of one signal spatial characteristic by another signal spatial characteristic, or the determination of one signal spatial filter by another signal spatial filter, may refer to: the spatial relationship (or spatial characteristic or spatial filter) of the transmitting signal is determined according to the receiving signal, or the spatial relationship (or spatial characteristic or spatial filter) of the receiving signal is determined according to the transmitting signal. It can also be that the spatial relationship (or spatial characteristic or spatial filter) of the transmitting signal is determined according to the spatial relationship (or spatial characteristic or spatial filter) of the receiving signal, or the spatial relationship (or spatial characteristic or spatial filter) of the receiving signal is determined according to the spatial relationship (or spatial characteristic or spatial filter) of the transmitting signal. It can also be that the transmitting beam is determined according to the receiving beam, or the receiving beam is determined according to the transmitting beam.

[0224] For example, the third measurement method is the Doppler measurement method:

[0225] In order to obtain the moving speed of the target, a Doppler measurement method can be configured. When the received signal strength of the first perception signal after reflection is higher than a threshold (the specific value of the threshold is not limited and can be configured based on the situation), the first device can obtain information such as the Doppler offset value or speed value of the perception target by sending and receiving the first perception signal.

[0226] In addition, the measurement method of the first perception signal may be predefined, self-selected, reported by the first device to the second device, or indicated.

[0227] For example, the measurement method of the first perception signal is predefined, and the first device can measure the first perception signal according to the predefined measurement method to obtain a corresponding measurement result;

[0228] For example, the measurement method of the first perception signal is selected by itself, and the first device can select the measurement method by itself according to the received perception requirement to measure the first perception signal and obtain the corresponding measurement result.

[0229] In some embodiments, when reporting the measurement results, the first device may indirectly indicate the measurement method by reporting the corresponding measurement results or optionally report the measurement methods used at the same time, or the first device may report the measurement results and the measurement method used separately.

[0230] For example, the measurement method of the first perception signal is reported by the first device to the second device (e.g., the first device reports to the second device that the first device supports the first measurement method, and the second device may determine that the first device will use the first measurement method to measure the first perception signal). The first device may measure the first perception signal according to the reported measurement method of the first perception signal and obtain a corresponding measurement result.

[0231] For example, the measurement method of the first perception signal is indicated. For example, the second apparatus further sends third configuration information to the first apparatus, where the third configuration information is used to indicate the measurement method of the first perception signal. The first apparatus may measure the first perception signal according to the measurement method of the first perception signal indicated by the third configuration information, and obtain a corresponding measurement result.

[0232] In one possible implementation, the measurement result of the first perception signal includes at least one of the following:

[0233] Identification of the transmission resource;

[0234] Received signal strength;

[0235] The received signal strength of each multipath component;

[0236] The time difference between the sending time and the receiving time;

[0237] Receive timestamp;

[0238] The difference between the receiving timestamp and the receiving timestamp of the second perception signal, where the second perception signal is a signal sent by the second device to the first device.

[0239] The transmission resource identifier is used to indicate the transmission resource used to transmit the first perception signal. For example, the first device may transmit the first perception signal based on the transmission resource indicated by the transmission resource identifier. The second device may determine the transmission resource corresponding to the measurement result of the first perception signal based on the transmission resource identifier reported by the first device.

[0240] When the second device configures resources for perception signal transmission for different first devices respectively, by reporting the identifier of the transmission resource, the second device can distinguish the first device corresponding to each perception signal, and will not confuse the correspondence between the sender of the measurement result of the perception signal and the measurement result of the perception signal.

[0241] The received signal strength is used to indicate the strength of the reflected first perception signal received by the first device, and may be represented by reference signal received power (RSRP), but it is not limited to other possible terms to be used for representation in the future.

[0242] The received signal strength of each multipath component refers to the received signal strength corresponding to each path when the first device receives the first perception signal after reflection through multiple paths. In this way, the reflected signals from the perception targets corresponding to multiple paths can be obtained.

[0243] It should be noted that the signals reflected from the perception targets corresponding to multiple paths may come from multiple different perception targets, which helps to perceive multiple perception targets; if the signals reflected from the perception targets corresponding to multiple paths come from the same perception target, this helps to accurately perceive the position of the perception target.

[0244] The time difference between the sending time and the receiving time is used to represent the difference between the sending time of the first perception signal and the receiving time of the first perception signal, which may be an absolute time.

[0245] The received timestamp is used to indicate the timestamp corresponding to when the first device receives the first sensing signal. It can be used to indicate the time when the measurement occurred and to reflect the time corresponding to the measurement result obtained through the measurement, which helps to track the sensing target according to time.

[0246] Among them, the difference between the receiving timestamp and the receiving timestamp of the second perception signal is used to represent the time difference between them. The reporting overhead can be reduced by reporting the receiving timestamp of the second perception signal (the perception signal sent by the second device to the first device) and the time difference therewith, while ensuring that the receiving end can obtain these two timestamps.

[0247] In one possible implementation, the measurement result of the above-mentioned first perception signal may further include at least one of the following: a sending timing error group (TEG) identifier, a receiving TEG identifier, and a sending and receiving TEG identifier, where the "sending and receiving TEG identifier" represents the identifier of the TEG consisting of the sending timing error and the receiving timing error.

[0248] By reporting the TEG identifier, the second device can determine which results reported by the first device belong to the same TEG and which belong to different TEGs. Results with the same TEG identifier belong to the same error group or the same error range. With this identification, the second device can process the results separately based on the TEG identifier, helping to improve the accuracy of the measurement results.

[0249] The above description of the measurement result of the first perception signal may correspond to the first measurement method, the second measurement method, or the third measurement method. For example, when the first perception signal is measured using the third measurement method, the measurement result of the first perception signal corresponding to the third measurement method may also include at least one of the above contents; when the first perception signal is measured using the second measurement method, the measurement result of the first perception signal corresponding to the second measurement method may also include at least one of the above contents.

[0250] In one possible implementation, the measurement result of the first perception signal includes at least one of the following:

[0251] Identification of the transmission resource;

[0252] Send beam;

[0253] Receive beam;

[0254] Received signal strength;

[0255] The received signal strength of each multipath component;

[0256] Receive timestamp.

[0257] The transmit beam is the beam through which the first device transmits the first perception signal, and the receive beam is the beam through which the first device receives the first perception signal. By reporting the transmit beam or receive beam, the second device can determine the target's position information. The description of the transmission resource identifier, received signal strength, received signal strength of each multipath component, and receive timestamp can be found in the previous description and will not be repeated here.

[0258] The above description of the measurement result of the first perception signal may correspond to the second measurement method, the first measurement method, or the third measurement method. For example, when the first measurement method is used to measure the first perception signal, the measurement result of the first perception signal corresponding to the first measurement method may also include at least one of the above contents; when the third measurement method is used to measure the first perception signal, the measurement result of the first perception signal corresponding to the third measurement method may also include at least one of the above contents.

[0259] In one possible implementation, the measurement result of the first perception signal includes at least one of the following:

[0260] Identification of the transmission resource;

[0261] A Doppler shift value obtained based on the first sensing signal;

[0262] a speed value of the perception target obtained based on the first perception signal;

[0263] Receive timestamp.

[0264] The Doppler shift value obtained based on the first perception signal may be used to indicate the moving speed of the perception target, which may be obtained by comparing the frequency difference between the transmitted first perception signal and the received first perception signal.

[0265] The moving speed of the sensing target obtained based on the first sensing signal can be obtained by using the Doppler frequency shift and the carrier wavelength (for example, F d =2*v / lamda), F d is the Doppler shift, v is the moving speed, and lamda is the carrier wavelength.

[0266] The speed value of the sensed target obtained based on the first sensing signal can also be used to indicate the moving speed of the target. The description of the identification of the transmission resource and the receiving timestamp can be found in the above description and will not be repeated here.

[0267] The above description of the measurement result of the first perception signal may correspond to the third measurement method, the second measurement method, or the first measurement method. For example, when the first measurement method is used to measure the first perception signal, the measurement result of the first perception signal corresponding to the first measurement method may also include at least one of the above contents; when the second measurement method is used to measure the first perception signal, the measurement result of the first perception signal corresponding to the second measurement method may also include at least one of the above contents.

[0268] In one possible implementation, the first measurement method, the second measurement method, and the third measurement method described above may be combined. For example, the first device measures the first perception signal using the first measurement method and the second measurement method, or the first device measures the first perception signal using the second measurement method and the third measurement method; or the first device measures the first perception signal using the first measurement method, the second measurement method, and the third measurement method. Accordingly, a measurement result obtained by the first device measuring the first perception signal is associated with the measurement method used by the first device.

[0269] S202. The first device sends a measurement result of the first perception signal to the second device.

[0270] Correspondingly, the second device receives the measurement result of the first sensing signal.

[0271] For example, the first device completes the self-transmission and self-reception of the first perception signal according to the first configuration information, and measures the first perception signal (for the description of the measurement method, please refer to the previous text), obtains the measurement result of the first perception signal, and sends the measurement result of the first perception signal to the second device according to the second configuration information.

[0272] Accordingly, the second device processes the measurement result of the first perception signal.

[0273] In summary, the first device can complete the perception task relatively independently based on the configuration information about the perception signal sent by the second device (including the transmission of the perception signal and the transmission of the measurement result of the perception signal).

[0274] In addition, there is no need for much signaling interaction between the first device and the second device, thereby reducing the signaling interaction overhead between the first device and the second device for completing the perception task.

[0275] In one possible implementation, the first device may not send the measurement result of the first perception signal to the second device. For example, the first device may first process the measurement result of the first perception signal, and then send the information obtained by the first device after processing the measurement result of the first perception signal to the second device. In this way, feedback signaling overhead and processing power consumption of the second device can be reduced.

[0276] The method shown in FIG2 is further described below in conjunction with FIG3 and FIG4.

[0277] FIG3 is a schematic diagram of an interaction process of another sensing method according to an embodiment of the present application. As shown in FIG3 , the method includes:

[0278] Optionally, S301, the second device sends first information to the first device.

[0279] Correspondingly, the first device receives the first information.

[0280] The first information is used to indicate a constraint condition. A device that satisfies the constraint condition (described using the first device as an example) performs at least one of perception measurement and capability reporting:

[0281] For example, devices that meet the constraints perform perception measurements;

[0282] For example, the execution capability report of the device that meets the constraint conditions;

[0283] For example, devices that meet the constraint conditions perform perception measurements and capability reporting.

[0284] The device performing the perception measurement may include: after the device completes capability reporting (capabilities related to the perception signal may be referred to as perception capabilities), the device performs the perception measurement; or, the device performs the perception measurement without reporting capabilities. The perception measurement may include participating in the perception execution, etc.

[0285] The above-mentioned device execution capability reporting may be: the device determines that after the constraint condition is met, it reports its capability (hereinafter referred to as capability (also referred to as perception capability)) related to transmission and / or measurement of the perception signal to the second device.

[0286] For ease of description, the following description is made by taking the case where a device that meets the constraint conditions performs capability reporting as an example, but the application scenario is not limited to the case where a device that meets the constraint conditions performs perception measurement.

[0287] The first information may be carried in the system information, or the first information may be the system information. In this way, the constraint information may be broadcast to devices in different RRC states, so that as many devices as possible that meet the constraint conditions may report their capabilities.

[0288] In one possible implementation, the above constraints include at least one of the following:

[0289] Received signal strength, bandwidth capability, geographic location range, beam range, type of duplex capability, measurement method (or sensing method), beam reciprocity, maximum number of antenna ports, speed range, and device type.

[0290] For example, devices that receive a specific signal with a received signal strength above a certain threshold are required to perform at least one of perception measurement and capability reporting. The specific signal can be a downlink signal or a sidelink signal, without limitation. Requiring the received signal strength to be above a certain threshold ensures that only devices with relatively good channel quality participate in the perception measurement, thereby ensuring the reliability and accuracy of the measurement result reporting.

[0291] For example, devices supporting a specific bandwidth may be required to perform at least one of perception measurement and capability reporting. For example, devices supporting bandwidths greater than 10 Mbps may be required to perform at least one of perception measurement and capability reporting. Requiring devices to support bandwidths greater than a certain threshold is necessary to meet time resolution or range resolution requirements. The bandwidth capability described above may indicate the bandwidth a device can support for transmitting perception signals.

[0292] For example, devices within a specific geographic location are required to perform at least one of perception measurements and capability reporting. Requiring devices within a specific geographic location to participate in perception measurements can satisfy perception requirements. For example, if a second device needs to perceive a specific geographic area, the second device can communicate with a first device within that area, enabling the first device within that area to complete the perception task, thereby assisting the second device in completing its perception of that area.

[0293] For example, devices within a specific beam range are required to perform at least one of perception measurements and capability reporting. Devices within a specific beam range are required to participate in perception measurements to meet perception requirements. For example, if a second device needs to perceive an area within a specific angle range, the second device can communicate with a first device within the specific angle range, allowing the first device within the specific angle range to complete the perception task, thereby assisting the second device in completing perception of the area within the specific angle range.

[0294] For example, a device that meets a specific duplex capability is required to perform at least one of perception measurement and capability reporting. Duplex modes (also referred to as perception duplex modes) include half-duplex mode and full-duplex mode. Obtaining the duplex capability of the first device by the second device helps the second device to specifically configure the perception receiving window time range of the first device and, at the same time, helps the second device to determine the minimum perceptible measurement distance corresponding to different duplex modes of the first device.

[0295] For example, devices that support a specific measurement method may be required to perform at least one of perception measurement and capability reporting. In this way, the second device can configure perception measurement of the perception signal based on the perception requirement and the measurement method supported by the first device. For example, if the first device supports an angle-based measurement method that is insensitive to bandwidth, the second device can configure a relatively small perception signal bandwidth for the first device to perform angle measurement reporting to meet the perception requirement.

[0296] For example, devices that meet beam reciprocity are required to perform at least one of perception measurement and capability reporting. This allows the second device to simultaneously configure either the receive beam or the transmit beam by only configuring the transmit beam or receive beam of the first device. This allows the first device to simultaneously configure both the transmit beam and receive beam pair, helping to reduce signaling overhead. The first device then performs measurement and reporting based on the perception signal transmitted by the transmit beam and receive beam pair.

[0297] For example, the device with the maximum number of antenna ports greater than a threshold is required to perform at least one of perception measurement and capability reporting. In this way, the second device can configure the corresponding time-frequency transmission resources of the perception signal to perform perception measurement and reporting.

[0298] For example, devices within a specific speed range are required to perform at least one of perception measurement and capability reporting. Devices within the specific speed range are required to participate in perception measurement to meet perception requirements. These perception requirements may include one or more of distance, speed, angle, and corresponding accuracy requirements, resolution requirements, confidence requirements, detection accuracy, missed detection probability, false alarm probability, and latency requirements.

[0299] For example, devices that meet certain device types are required to perform at least one of perception measurement and capability reporting, where the device types include UE, relay equipment, base station, and sensor.

[0300] The device type may include devices in a low-power state, such as an RRC idle UE, an RRC inactive UE, or a low-power connected UE. By performing at least one of perception measurement and capability reporting, a second device that meets the specific device type can configure a corresponding perception signal for the corresponding first device, enabling the device of the specific device type to participate in perception collaboration with low power consumption and low overhead, thereby meeting the perception task requirements of the second device.

[0301] In summary, limiting the number of devices that meet the constraints to perform at least one of perception measurement and capability reporting helps reduce interference between different devices. In other words, by configuring the constraints, embodiments of the present application can avoid resource conflicts caused by too many devices competing for resources when reporting measurement results, thereby affecting the second device's reception of the measurement results of the perception signal.

[0302] Optionally, S302: The second device sends second information to the first device.

[0303] Accordingly, the first device receives the second information. The second information is used to request feedback of capability information of the first device. The capability information of the first device is used to indicate the capability of the first device to associate with the first perception signal. For example, the capability of the first device to associate with the first perception signal may include: one or more of: a capability to send the first perception signal, a capability to receive the first perception signal, a capability to measure the first perception signal, and a capability to send the measurement result of the first perception signal to the second device, etc., without limitation.

[0304] The second information can be carried in the system information, or the second information can be the system information. In this way, the capability request information can be broadcast to devices in different RRC states, enabling as many devices as possible that meet the constraint conditions to report their capabilities. These devices that report their capabilities then receive the capability reporting response information and perform perception measurement reporting based on the capability reporting response information.

[0305] In one possible implementation, the capability information of the first device includes at least one of the following:

[0306] Bandwidth capability, type of duplex capability, measurement methods, beam reciprocity capability, and maximum number of antenna ports.

[0307] The bandwidth capability may be used to indicate the bandwidth supported by the first device for sending and receiving the first perception signal.

[0308] In one possible implementation, the above-mentioned bandwidth capability can be indicated by configuring multiple values ​​or intervals, such as bandwidth capability less than B1, bandwidth capability greater than or equal to B1 and bandwidth capability less than or equal to B2, bandwidth capability greater than B2 and less than or equal to B3, and bandwidth capability greater than B3, for the first device to select feedback.

[0309] The first device can directly feedback the index value corresponding to the corresponding interval. For example, using 2 bits to represent, for example, bit 00 indicates that the bandwidth (or bandwidth capability) supported by the first device is less than B1, bit 01 indicates that the bandwidth (or bandwidth capability) supported by the first device is greater than or equal to B1 and the bandwidth capability is less than or equal to B2, bit 10 indicates that the bandwidth (or bandwidth capability) supported by the first device is greater than B2 and less than or equal to B3, and bit 11 indicates that the bandwidth (or bandwidth capability) supported by the first device is greater than B3. When considering using a payload to carry the capability information of the first device, the first device may also send the maximum bandwidth it can support separately or together.

[0310] In one possible implementation, the types of duplex capability include full-duplex capability and half-duplex capability. The type of duplex capability can reflect the ability of the first device to perform full-duplex perception or half-duplex perception, which can affect the distance range of the first device's perception. The first device can provide feedback on whether it supports full-duplex capability or half-duplex capability. By reporting the duplex capability of the first device, the second device can configure the perception receiving window time range of the first device in a targeted manner. At the same time, it helps the second device to determine the minimum perceptible measurement distance corresponding to different duplex modes of the first device.

[0311] For descriptions of measurement methods, please refer to the aforementioned descriptions of the first measurement method, the second measurement method, and the third measurement method, which will not be repeated here. By reporting the measurement methods supported by the first device, the second device can configure the perception measurement of the perception signal in combination with the perception requirements and the measurement methods supported by the first device. For example, if the first device supports an angle-based measurement method, which is insensitive to bandwidth, the second device can configure a relatively small perception signal bandwidth to the first device for angle measurement reporting to meet the perception requirements.

[0312] Beam reciprocity capability refers to the association between the transmit beam and the receive beam. For example, the receive beam can be determined by the transmit beam, or the transmit beam can be determined by the receive beam, etc. The first device can provide feedback on whether there is reciprocity between its transmit beam and receive beam. By reporting the beam reciprocity capability information of the first device, if the first device supports beam reciprocity, the second device can simultaneously complete the configuration of the receive beam or the transmit beam by only configuring the transmit beam or the receive beam of the first device, that is, configuring the transmit beam and receive beam pair of the first device at the same time, which helps to reduce signaling overhead. Then, the first device measures and reports the perception signal transmitted based on the transmit and receive beam pair.

[0313] The maximum number of antenna ports affects the network's allocation of resources for transmission by each antenna port. This maximum number of antenna ports may include one or more of: the number of code-division ports, the number of frequency-division ports, the number of time-division ports, the maximum number of antenna ports, and multi-port scanning to increase scanning speed. By reporting the maximum number of antenna ports supported by the first device, the second device can configure the corresponding time-frequency transmission resources for the perception signal to perform perception measurement reporting.

[0314] It should be noted that the first information and the second information can be carried in the same information or message, such as system information (SI) (or perception system information, not limited to this), or can be carried in different information. When the first information and the second information are carried in different information, the first information and the second information can be sent simultaneously or at different times (for example, the first information is sent first or the first information is sent later), without limitation.

[0315] Optionally, S303: The first device sends capability information of the first device to the second device.

[0316] Correspondingly, the second device receives the capability information of the first device.

[0317] The first device determines whether to report the capability information of the first device to the second device based on whether the constraint condition is met. If the constraint condition is met, the capability information of the first device is sent to the second device; if the constraint condition is not met, the capability information of the first device is not sent to the second device.

[0318] The capability information of the first device can be used by the second device to configure corresponding first configuration information and second configuration information for the first device according to the capability of the first device, so that the first device can better complete the perception task within its capability.

[0319] In one possible implementation, the first device sends the capability information of the first device to the second device, including:

[0320] The first device sends the capability information of the first device to the second device via a preamble and a payload. For example, the first device randomly selects a preamble and its corresponding channel from a preamble resource pool configured by the second device to send the capability information of the first device to the second device. The channel carries a payload for carrying the capability information of the first device, and the preamble is used to distinguish different first devices; or

[0321] A first device transmits its capability information to a second device via a preamble. For example, when the capability information of the first device requires less information to indicate, the first device may select a preamble matching its capabilities from a preamble resource pool based on a predefined or preconfigured relationship between preambles and capabilities, and transmit the capability information to the second device. The number of preambles matching the capability information may be greater than one to reduce conflicts when different first devices select the same preamble.

[0322] If the first device is a non-connected device, the first device can send the capability information of the first device via a preamble and a payload, or the first device can send the capability information of the first device via a preamble, which can reduce latency and signaling interaction overhead.

[0323] If the first device is a connected device, it can also send its capabilities information to the second device via an uplink or sidelink. Using a preamble + payload or preamble to send the capabilities information can reduce latency and signaling overhead. In one possible implementation, after the first device reports its capabilities information to the second device, the second device can decide not to participate in the sensing measurement for one or more of the first devices.

[0324] In another possible implementation, after the first device reports the capability information to the second device, the first device may also choose not to participate in the perception measurement, which is not limited.

[0325] S304. The second device sends first configuration information and second configuration information to the first device.

[0326] Correspondingly, the first device receives the first configuration information and the second configuration information.

[0327] For the description of the first configuration information and the second configuration information, please refer to the description of S201 above and will not be repeated here.

[0328] After the first device sends the capability information of the first device to the second device, the second device sends capability reporting response information (such as sensing report response (SRR)) to the first device, which is used to respond to the capability information sent by the first device.

[0329] In one possible implementation, the first configuration information and / or the second configuration information may be carried in the capability reporting response information, or the first configuration information and / or the second configuration information may be capability reporting response information, without limitation. This allows the device that meets the constraint conditions for capability reporting to read the response information and perform further perception measurement reporting, rather than other devices.

[0330] In another possible implementation, the first configuration information and / or the second configuration information may be carried in system information. This allows devices in various RRC states to receive the information, and allows devices that meet the constraint conditions to report capabilities or perception measurements based on the indication information.

[0331] Among them, the above-mentioned capability reporting response information may include physical layer control signaling and media access control (MAC) layer control signaling, and the physical layer control signaling is used to indicate part or all of the transmission resource configuration of the physical layer downlink shared channel (PDSCH), the configuration of the first perception signal, and the transmission configuration of the measurement result of the first perception signal.

[0332] In some embodiments, the capability reporting response includes indicating through control information, such as carrying information indicating resource configuration of a data channel and sending and receiving of a first perception signal, as well as information of a perception measurement method through control information.

[0333] In some embodiments, downlink control information (DCI) in the physical layer control signaling carries information indicating PDSCH resource configuration and transmission and reception of the first perception signal, as well as a perception measurement method.

[0334] In some embodiments, the primary DCI in the physical layer control signaling indicates PDSCH resource configuration and the sending and receiving of the first perception signal; the secondary DCI indicates the perception measurement method.

[0335] For example, the first-level DCI can be carried by the physical downlink control channel (PDCCH), and the second-level DCI can be carried by the PDSCH. The MAC control element (CE) in the MAC layer control signaling can be used to indicate the transmission resource configuration of the measurement result of the first perception signal, which includes one or more of the time-frequency resource location of the PUSCH, the MCS configuration of the PUSCH, and the timing advance configuration. Among them, the MAC CE is carried by the PDSCH for transmission.

[0336] The second device obtains the capability information of the first device and can configure at least one of the first configuration information and the second configuration information that matches the capability of the first device for the first device according to the capability information of the first device.

[0337] Exemplarily, the first configuration information is associated with the capability of the first device, and / or the second configuration information is associated with the capability of the first device.

[0338] For example, the first configuration information is configured by the second device according to the capability of the first device, and / or the second configuration information is configured by the second device according to the capability of the first device.

[0339] For a description of the association relationship between the first configuration information and the capability of the first device, see Table 1. For a description of the association relationship between the second configuration information and the capability of the first device, see Table 2.

[0340] Table 1

[0341] Exemplarily, the first configuration information is used to configure parameter 1, parameter 2, and parameter 3, where parameter 1 is associated with bandwidth 1, parameter 2 is associated with bandwidth 2, and parameter 3 is associated with bandwidth 3. For example, bandwidth 1 may be 10M, bandwidth 2 may be 15M, and bandwidth 3 may be 20M.

[0342] In combination with Table 1, if the maximum bandwidth supported by the first device is 10M, the first device selects parameter 1 according to its own bandwidth capability; if the maximum bandwidth supported by the first device is 20M, the first device selects parameter 3 according to its own bandwidth capability or selects any one of parameters 1-parameter 3 according to predefined rules.

[0343] The second device can configure corresponding parameters for transmitting perception signals according to the bandwidth capabilities of different devices, and the first device can determine appropriate parameters for transmitting the first perception signal according to its own bandwidth capabilities, which can enable each device to better perform perception tasks within the bandwidth range.

[0344] The above-mentioned association between parameters and bandwidth is only an example, and it can also be associated with more capabilities (such as the type of duplex capability, beam reciprocity capability, and the maximum number of antenna ports, etc.). For ease of description, the embodiment of the present application takes the association between parameters configured by the first configuration information and bandwidth as an example, but is not limited to other scenarios.

[0345] In one possible implementation, the second device may configure multiple configuration information based on the capabilities of multiple first devices, or may configure one configuration information based on the capabilities of multiple first devices, where the one configuration information includes multiple parameters, and the multiple parameters are associated with the capabilities of multiple first devices.

[0346] For example, the above parameter 1 is associated with the bandwidth capability of device 1, parameter 2 is associated with the bandwidth capability of device 2, parameter 3 is associated with the bandwidth capability of device 3, and so on. In this way, the first device can determine the corresponding parameter based on its own bandwidth capability and transmit the perception signal based on the parameter.

[0347] Table 2

[0348] Exemplarily, the second configuration information is used to configure resource 1, resource 2, and resource 3. Resource 1 is associated with bandwidth 1, resource 2 is associated with bandwidth 2, and resource 3 is associated with bandwidth 3. For example, bandwidth 1 can be 10M, bandwidth 2 can be 15M, and bandwidth 3 can be 20M.

[0349] Combined with Table 2, if the maximum bandwidth supported by the first device is 10M, the first device selects resource 1 according to its own bandwidth capability; if the maximum bandwidth supported by the first device is 20M, the first device selects resource 3 according to its own bandwidth capability or selects any one of resources 1-resource 3 according to predefined rules.

[0350] The above resource-bandwidth association is merely an example. It can also be associated with more capabilities, such as the maximum number of antenna ports, beam reciprocity capability, and duplex capability type, without limitation. For ease of description, this embodiment of the application uses the resource-bandwidth capability association configured by the second configuration information as an example, but is not limited to other scenarios.

[0351] The second device can configure one or more resources for transmitting the measurement results of the perception signal according to different parameters for transmitting the perception signal, which can enable different devices to select different resources when performing resource selection, thereby avoiding resource conflicts.

[0352] In addition, since the first parameter is associated with the first resource, when the first device sends the measurement result of the first perception signal to the second device through the first resource, the second device can determine the first parameter selected by the first device based on the first resource. This can prevent the first device from reporting the parameters selected for transmitting the first perception signal to the second device, thereby reducing signaling interaction overhead.

[0353] It should be noted that multiple resources, such as orthogonal time domain resources, frequency domain resources, code domain resources (or sequences), or quasi-orthogonal code domain resources (or sequences), can be configured for the same bandwidth sensing signal. After the first device selects the bandwidth, it can randomly select a sensing signal sequence from the resource pool corresponding to the bandwidth for transmission, thereby reducing the collision probability during sensing signal transmission. For example, multiple sequences of the same length in the sensing signal resource pool correspond to the same bandwidth and are configured on the same time-frequency resources. These sequences of the same length can be orthogonal sequences, such as those with the same ZC sequence root but different cyclic shifts, or ZC sequences of the same length but different roots, i.e., quasi-orthogonal sequences. Using orthogonal time-frequency resources or orthogonal sequences can provide better performance by avoiding mutual interference between sequences. Quasi-orthogonal sequences have slightly inferior performance due to slight interference between sequences. By configuring multiple sequences with different time-frequency resources, or orthogonal sequence resources, or multiple quasi-orthogonal sequences, multiple devices can be supported to perform random sequence selection, reducing the collision probability and improving detection performance.

[0354] In one possible implementation, the second device may configure multiple configuration information based on the capabilities of multiple first devices, or configure one configuration information based on the capabilities of multiple first devices, where the configuration information includes multiple resources, and the multiple resources are associated with the capabilities of multiple first devices.

[0355] For example, resource 1 is associated with the bandwidth capability of device 1, resource 2 is associated with the bandwidth capability of device 2, resource 3 is associated with the bandwidth capability of device 3, and so on. In this way, the first device can determine the corresponding resource based on its own bandwidth capability and transmit the measurement result of the perception signal based on the resource.

[0356] In one possible implementation, the first device may determine the second resource based on the bandwidth capability of the first device, and the second configuration information is used to configure at least one resource, where the at least one resource includes the second resource; the first device sends the measurement result of the first perception signal through the second resource.

[0357] The first device sends the measurement result of the first perception signal by using the second resource corresponding to the bandwidth capability, which helps the second device obtain the bandwidth corresponding to the measurement result of the first perception signal through the second resource, without the first device carrying the bandwidth in the measurement result of the first perception signal, thereby reducing the signaling indication overhead.

[0358] In an embodiment of the present application, the second device can configure a resource pool for each or multiple parameters, and each resource in the resource pool can be used to transmit the measurement results of the perception signal. For example, the second device configures a resource pool for parameter 1. After determining parameter 1, the first device can randomly select resources in the resource pool associated with parameter 1, and transmit the measurement results of the first perception signal based on the selected resources; or, the second device can configure a resource pool, and the resources in the resource pool can be used by multiple first devices to transmit the measurement results of the perception signal. Each first device can select a resource from the resource pool to transmit the measurement results of the perception signal; or, the second device can configure a resource pool for each bandwidth. Different first devices can select a suitable resource pool according to their own bandwidth capabilities, and randomly select resources from the resource pool to transmit the measurement results of the perception signal. This can reduce the conflict of feedback resources caused by different first devices selecting the same feedback resources when reporting the perception measurement results. In addition, the resource pool includes multiple orthogonal or pseudo-orthogonal sequences, and the sequences of different sensing signals have the same length or correspond to the same bandwidth. They can be Zadoff-Chu (ZC) sequences, m-sequences, or frequency modulated continuous wave (FMCW) waveforms.

[0359] In addition, each parameter or sequence of the resource pool may correspond to a channel, which is used to carry the load of the measurement result feedback, and the sequence is used to distinguish the measurement result reports of different first devices. Optionally, multiple parameters may correspond to one channel.

[0360] In one possible implementation, the second device can determine the first parameter (for example, the aforementioned parameter 1) based on the available carrier frequency, perception requirements, and capabilities of the first device, and configure it to the first device. The first device can transmit a first perception signal based on the first parameter; or, the first device can determine the first parameter based on the bandwidth capability of the first device, and transmit the first perception signal based on the first parameter.

[0361] For example, the first configuration information may configure at least one parameter, each parameter being used for transmission of a perception signal, the at least one parameter including a first parameter (such as parameter 1 described above), and the first device transmitting the first perception signal based on the first parameter. For a description of how the first device determines the first parameter based on the bandwidth capability of the first device, please refer to the description in Table 1 and will not be repeated here.

[0362] For another example, the second device may provide at least one parameter (or a parameter set) for each bandwidth (carried in a configuration message), and each parameter may be used to transmit the perception signal. The first device may determine an appropriate bandwidth based on its own bandwidth capabilities, and then select a parameter from at least one parameter corresponding to the bandwidth to transmit the first perception signal.

[0363] In one possible implementation, the first device may further send the bandwidth of the first perception signal measured by the first device to the second device. Correspondingly, the second device receives the bandwidth of the first perception signal measured by the first device.

[0364] For example, the first device may further report to the second device the bandwidth when the first device measures the first perception signal.

[0365] The bandwidth used to measure the first perception signal may be a bandwidth index value. By reporting the bandwidth of the first perception signal measured by the first device (which may be carried simultaneously), the second device can obtain the bandwidth value corresponding to the measurement result of the first perception signal, which helps the second device perform further processing based on multiple measurement results from the same bandwidth, thereby improving the accuracy of the measurement result.

[0366] In one possible implementation, the bandwidth for measuring the first perception signal corresponds to the measurement result of the first perception signal. In this way, the second device can determine the bandwidth at which the measurement result of the first perception signal was obtained based on the bandwidth at which the first device measured the first perception signal. This allows the second device to further process multiple measurement results corresponding to the same bandwidth, thereby improving perception performance and the quality of the perception results.

[0367] In one possible implementation, the first device may further send a preamble code used by the first device to report the capability information to the second device.

[0368] The preamble code is the preamble code used by the first device when reporting the capabilities of the first device. The second device will configure the perception signal bandwidth according to the bandwidth capability reported by the first device, and at the same time establish a correspondence between the bandwidth capability and the preamble code of the device with the capability. By reporting the preamble code used by the first device to report capability information, the second device can determine the bandwidth used by the first device based on the correlation between the preamble code and the bandwidth and the preamble code, and then determine the bandwidth value corresponding to the measurement result of the first perception signal, which helps the second device to perform further processing based on multiple measurement results from the same bandwidth, thereby improving the accuracy of the measurement results.

[0369] In one possible implementation, the preamble code used by the first device to report the capability information corresponds to the measurement result of the first perception signal.

[0370] In this way, the second device can determine the bandwidth when the first device measures the first perception signal based on the preamble code, and then determine the bandwidth corresponding to the measurement result of the first perception signal. This is conducive to the second device to further process multiple measurement results from the same bandwidth, thereby improving the accuracy of the measurement results.

[0371] In one possible implementation, the first parameter includes at least one of the following:

[0372] Subcarrier spacing, cyclic prefix length, transmission time, receiving window time, bandwidth, frequency starting position, sequence (which corresponds to the perception signal sequence, such as reused reference signal sequence or the perception signal is also used as a reference signal), transmission beam and reception beam.

[0373] By configuring the bandwidth in each parameter, the first device can select appropriate parameters to transmit the first perception signal according to its own bandwidth capability.

[0374] In one possible implementation, the first parameter includes at least one of the following:

[0375] Subcarrier spacing, cyclic prefix length, transmit time, receive window time, frequency start position, sequence, transmit beam, and receive beam.

[0376] The transmit / receive beam may be a beam that is reciprocal or quasi-co-located (QCL) with a synchronization signal block (synchronization signal and physical broadcast channel block, SSB).

[0377] Specifically, the first parameter does not include bandwidth, and an association relationship between the first parameter and bandwidth can be set. In this way, the first device can determine appropriate parameters for transmitting the first perception signal based on the association relationship between bandwidth and parameters and its own bandwidth capability.

[0378] In addition, the second configuration information may also be used to configure at least one resource, and a resource in the at least one resource may be associated with a parameter configured by the first configuration information, for example, parameter 1 is associated with resource 1, parameter 2 is associated with resource 2, and so on. After the first device determines appropriate parameters based on the first configuration information, it may determine appropriate resources based on the parameters and the second configuration information, thereby completing the transmission of the measurement result of the first perception signal.

[0379] In one possible implementation, the second configuration information may also be used to configure at least one resource, and each resource may be associated with a bandwidth capability of the device, for example, resource 1 is associated with bandwidth 1, resource 2 is associated with bandwidth 2, and so on. Therefore, the first device may determine a suitable resource based on its own bandwidth capability, and may then complete the transmission of the measurement result of the first perception signal based on the resource.

[0380] In summary, embodiments of the present application support configuring a resource pool for each bandwidth. The resources in the resource pool are used to transmit the measurement results of the perception signal. The first device can select a resource in the resource pool to transmit the measurement results of the first perception signal. Specifically, the first device can select a resource in the resource pool based on the sequence of the first perception signal (such as a ZC sequence, an M sequence, and an FMCW waveform). This can effectively reduce the probability of resource collision when transmitting the measurement results of the first perception signal.

[0381] In summary, embodiments of the present application support configuring a resource for each bandwidth and preamble selected by the first device. This resource is used to transmit the measurement results of the perception signal, and the first device can transmit the measurement results of the first perception signal using this resource. Allocation of feedback resources to the first device using the preamble effectively reduces the probability of resource collisions when transmitting the measurement results of the first perception signal.

[0382] In another possible implementation, parameter 1 can be associated with parameter 4 (e.g., the second parameter). Parameter 4 can be used to transmit a third perception signal, which is a perception signal sent by the first device to the second device. The contents of parameter 4 are described in the aforementioned description of the first parameter and are not further elaborated here.

[0383] In one possible implementation, the above-mentioned parameter 4 may be configured by fourth configuration information. The fourth configuration information and the first configuration information may be carried in the same information or in different information respectively, which is not limited.

[0384] It should be noted that parameter 1 and parameter 4 are associated. The first device can determine parameter 1 based on parameter 4 and the association between parameter 4 and parameter 1. For example, the subcarrier spacing in parameter 1 can be determined based on the subcarrier spacing in parameter 4. Exemplarily, the second device indicates the subcarrier spacing in parameter 1 to the first device based on the multiple or factor relationship between the subcarrier spacing in parameter 1 and the subcarrier spacing in parameter 4. The first device can determine the subcarrier spacing in parameter 1 based on the subcarrier spacing in parameter 4 and the multiple or factor relationship. In this way, the signaling overhead for indicating parameter 1 can be reduced.

[0385] In one possible implementation, the association between parameter 1 and parameter 4 can be as follows: some parameters in parameter 1 can be determined by parameter 4. For ease of description, the following example uses the case where the bandwidth in parameter 1 is determined based on the bandwidth in parameter 4. See Tables 3 to 5 for details.

[0386] Table 3

[0387] As shown in Table 3, differential indication is performed in an increasing direction with the reference bandwidth as the starting point. The first device receives a 4-bit reference bandwidth configuration indication (such as the fourth configuration information), which is 48 resource blocks (RBs) as shown in Table 1. Taking the indicated bandwidth value as the reference value, the first device also receives an additional 2-bit differential indication (such as the first configuration information), which indicates the offset value of the bandwidth of the first perception signal relative to the reference bandwidth, indicating the offset values ​​of 0, 16, 32, and 48 respectively, that is, the bandwidth of the corresponding first perception signal is 48, 64, 80, and 96.

[0388] Table 4

[0389] As shown in Table 4, starting from the reference bandwidth, differential indication is performed in a decreasing direction. The first device receives a 4-bit reference bandwidth configuration indication (such as the fourth configuration information), which is 144 RBs as shown in Table 4. Taking the indicated bandwidth value as the reference value, the first device also receives an additional 2-bit differential indication (such as the first configuration information), which indicates the offset value of the bandwidth of the first perception signal relative to the reference bandwidth, indicating the offset values ​​of 0, -16, -32, and -48, respectively, that is, the bandwidths corresponding to the first perception signal are 144, 128, 112, and 96.

[0390] Table 5

[0391] As shown in Table 5, starting from the reference bandwidth, differential indications are performed in the decreasing and increasing directions, respectively. The first device receives a 4-bit reference bandwidth configuration indication (such as the fourth configuration information), which is 64 RBs, as shown in Table 5. With this indicated bandwidth value as a reference value, the first device also receives an additional 2-bit differential indication (such as the first configuration information), which indicates the offset value of the bandwidth of the first perception signal relative to the reference bandwidth, indicating the offset values ​​of 0, -16, -32, 16, and 32, respectively, that is, the bandwidths corresponding to the first perception signal are 64, 48, 32, 80, and 96.

[0392] It should be noted that parameters 1 and 4 may include common parameters, such as transmission time domain resources, frequency domain resources (such as frequency starting position, bandwidth), transmission beam / angle, and transmission power. Among them, all or part of the parameters of parameter 4 can be used as a reference for parameter 1, including configuring the bandwidth of the first perception signal based on the differential bandwidth of the reference bandwidth, configuring the transmission beam of the first perception signal with the transmission beam of the third perception signal or its adjacent beam, configuring the identification of the transmission resources of each beam, and using the offset value of the transmission power of the third perception signal as the transmission power of the first perception signal.

[0393] Parameter 1 may include some unique parameters, such as the receiving beam or angle of the first perception signal (parameter 4 may not be configured), considering at least supporting the reciprocity between the transmitting beam and the receiving beam (the capability of the first device can be reported by the first device to the second device), and indicating the receiving beam through the transmitting beam; the receiving window start time and window length configuration for half-duplex / full-duplex, corresponding to the half-duplex receiving window start time being after the receiving perception symbol time, and the full-duplex receiving window start time overlapping with the transmitting perception symbol time.

[0394] In one possible implementation, the first device may send a third perception signal to the second device according to parameter 4. Correspondingly, the second device receives the third perception signal. In this way, the perception task of separate transmission and reception can be completed.

[0395] S305. The first device sends a measurement result of the first perception signal to the second device.

[0396] Accordingly, the second device receives the measurement result of the first sensing signal.

[0397] For example, for each transmission parameter of the perception signal (such as parameter 1, etc.), the embodiment of the present application can configure the resources used to report the measurement results of the perception signal or the preamble code (preamble) + data channel (data channel) configuration used.

[0398] The first device may transmit a measurement result of the first perception signal via a preamble and a data channel. Each perception signal transmission configuration may correspond to at least one preamble + data channel configuration. Each preamble + data channel configuration includes a preamble time-frequency resource, a preamble sequence, a data channel time-frequency resource, and a data channel demodulation reference signal (DMRS) configuration.

[0399] By associating multiple feedback resources with the transmission configuration of each perception signal, it is possible to reduce the conflict of feedback resources when perception measurement reporting caused by different first devices selecting the same feedback resource.

[0400] For example, the first device sending the measurement result of the first perception signal to the second device may include:

[0401] The first device determines resource 1 according to parameter 1, or the first device determines resource 1 according to the bandwidth capability of the first device, and sends the measurement result of the first perception signal to the second device through resource 1.

[0402] For the description of the first device determining resource 1 based on parameter 1 or bandwidth capability, please refer to the above description of Table 1 and Table 2, which will not be repeated here.

[0403] In one possible implementation, the first device sending the measurement result of the first perception signal to the second device may include:

[0404] The first device sends the measurement result of the first sensing signal to the second device in the form of a preamble and a payload; or,

[0405] The first device sends a measurement result of the first perception signal to the second device by means of a preamble code.

[0406] For the description of this, please refer to the above description of the first device sending the capability information of the first device to the second device, which will not be repeated here.

[0407] Optionally, S306: the second device sends feedback information to the first device.

[0408] Correspondingly, the first device receives the feedback information, which is used to indicate that the second device has received the measurement result of the first perception signal.

[0409] In summary, through the above technical solutions, the embodiments of the present application can support the first device to complete the perception task with lower signaling overhead.

[0410] In the above solution, the second device may further send system information (such as SIB1) to the first device for indicating reception of the first configuration information and the second configuration information. For example, the second device sends system information to the first device, where the system information includes a beam index for indicating reception of the first configuration information and the second configuration information, and the beam associated with the beam index is the beam for transmitting the first configuration information and the second configuration information. Specifically, the system information may indicate that a specific beam is used for transmitting the first configuration information and the second configuration information. The specific beam may be one beam or multiple beams.

[0411] The system information can be used to schedule the first configuration information and the second configuration information. For example, the system information includes: the reception window length of the first configuration information and the second configuration information (i.e., the time range in which the first information may be transmitted), broadcast or on-demand transmission, area range configuration (such as a specific beam configuration, a cell configuration, or a group of cell configuration), and period or duration information.

[0412] Since the system message is sent in multiple different beams corresponding to the SSB beam, the specific implementation method of indicating the beam index for receiving the first configuration information and the second configuration information in the system information can be that the system information sent in different beams all indicates the same beam index. In addition, the transmission beams of the first configuration information and the second configuration information can be specific. For example, the beam in the specific direction can be determined based on a sensing demand request (which can come from the CN or a network device). Carrying the same beam index in the system information sent through different beams is conducive to merging the receiving beams corresponding to adjacent system information.

[0413] FIG4 is a schematic diagram of an interaction process of another perception method according to an embodiment of the present application. As shown in FIG4 , the method includes:

[0414] Optionally, S401: The second device sends first information to the first device.

[0415] Accordingly, the first device receives the first information.

[0416] For the description of the first information, please refer to the description of the first information in FIG3 , which will not be repeated here.

[0417] The first information may be used to indicate that a device that meets the constraint condition may perform perception measurement and does not need to report capability information.

[0418] S402: The second device sends first configuration information and second configuration information to the first device.

[0419] Accordingly, the first device receives the first configuration information and the second configuration information.

[0420] In one possible implementation, the first information, the first configuration information, and the second configuration information may be carried in one message, or the first information, the first configuration information, and the second configuration information may be carried in different messages, respectively, which is not limited.

[0421] It should be noted that, when the first information, the first configuration information, and the second configuration information are respectively carried in different information, the first information, the first configuration information, and the second configuration information may be sent simultaneously or at different times.

[0422] In another possible implementation, the first configuration information is associated with the capability of the first device, or the second configuration information is associated with the capability of the first device.

[0423] For example, the capability pre-associated with the first configuration information is the capability of the first device, and / or the capability pre-associated with the second configuration information is the capability of the first device.

[0424] The second device can be pre-configured with multiple configuration information, each of which can be pre-associated with the capabilities of a device. When the second device sends multiple configuration information to multiple first devices, each first device can determine the corresponding configuration information based on its own capabilities. This eliminates the need for the first and second devices to exchange capability information, effectively reducing the signaling overhead associated with this exchange.

[0425] For the first configuration information and the second configuration information, please refer to the description of the first configuration information and the second configuration information in FIG3 , which will not be repeated here.

[0426] After receiving the first configuration information, the second configuration information, and the first information, the first device determines whether to perform the perception measurement based on whether the constraint conditions are met. The first device autonomously selects the transmission configuration of the first perception signal corresponding to its capabilities to send and receive the first perception signal and perform the perception measurement. Exemplarily, the first device selects the maximum bandwidth it can support based on its own capabilities (such as bandwidth capabilities) to transmit the first perception signal. At the same time, the first device can measure the received first perception signal based on its own duplex capability combined with the receiving resource configuration.

[0427] S403. The first device sends a measurement result of the first perception signal to the second device.

[0428] Accordingly, the second device receives the measurement result of the first sensing signal.

[0429] Specifically, the first device can transmit the first perception signal and the measurement result of the first perception signal according to the parameters for transmitting the first perception signal in the first configuration information that match the capabilities of the first device and the parameters for transmitting the measurement result of the first perception signal in the second configuration information that match the capabilities of the first device.

[0430] For the description of S403, please refer to the description of S305, which will not be repeated here.

[0431] Optionally, S404: the second device sends feedback information to the first device.

[0432] Correspondingly, the first device receives the feedback information, which is used to indicate that the second device has received the measurement result of the first perception signal.

[0433] In summary, through the above technical solutions, the embodiments of the present application can support the first device to complete the perception task.

[0434] In the above solution, in one possible implementation, the second device may send system information to the first device for instructing reception of the first configuration information and the second configuration information. For example, the second device sends system information to the first device, where the system information includes information indicating a beam index for receiving the first configuration information and the second configuration information, where the beam associated with the beam index is the beam for transmitting the first configuration information and the second configuration information. Alternatively, the system information may include information indicating a specific beam for transmitting the first configuration information and the second configuration information. The specific beam may be one beam or multiple beams.

[0435] Because system messages are sent in multiple different beams corresponding to SSB beams, a specific implementation method for indicating the beam index used for receiving the first configuration information and the second configuration information in the system information can be to indicate the same beam index in system information sent in different beams.
