Figure 1The vehicle equipment shown, such as the perception signaling between the vehicle equipment and the roadside unit, is transmitted through the vehicle network. Optionally, the terminal device may also integrate the perception management function. Optionally, the network device may be a node that is responsible for both communication and perception management, such as a dedicated node that integrates SEMF. SEMF is used to determine perception request information or configuration information based on perception demand information, and can also synthesize and calculate based on perception measurement results to obtain the results required by the perception target. Optionally, the perception measurement results include the geographic location, distance, speed, angle, map, posture, scale, imaging and material of the perception target. In other words, the device configured with SEMF has the ability to determine the required perception blocks, receive perception measurement results, and calculate the perception results based on the measurement results.

[0112] See also Figure 2 , Figure 2 It is a schematic diagram of another scenario of a perception network, which may include access network devices (such as network devices) and terminal devices, and the terminal devices may be unconnected terminal devices, connected terminal devices, passive terminal devices, idle terminal devices, inactive terminal devices or low-power terminal devices.

Figure 2 In the scenario of the perception network shown, perception signaling such as perception demand information, configuration request information, configuration information, etc. can occur between network devices and terminal devices such as through the Uu interface, or between terminal devices such as through the SL interface.

[0113] See also Figure 3 , Figure 31 is a schematic diagram of the structure of a sensing device provided in an embodiment of the present application. The sensing device can support a dedicated sensing node or a dedicated sensing mode, wherein in the dedicated sensing node or the dedicated sensing mode, the sensing device (such as a network device or a terminal device that performs a self-sensing operation) can interact with a device having a SEMF (such as a core network device, a network device or a terminal device) through a Uu interface, a SL interface, an F1 interface or a next generation (NG) interface, etc. for control and data. Optionally, the device with SEMF can be a core network device, a network device or a terminal device, and the perception device can be a network device or a terminal device. Therefore, the device with SEMF and the perception device can also interact through the interface between the network device and the terminal device, the interface between the terminal device and the terminal device, the interface between the core network device and the network device, the interface between the core network device and the terminal device, or the interface between the centralized unit and the distributed unit of the network device, such as the interaction of perception control (such as the configuration information described in this application) and data (such as the reporting of perception measurement results). The perception device receives the configuration information, which is used to configure the perception block. The perception device sends a perception signal on the first resource through the sending beam Tx according to the configuration information, and monitors the reflection signal of the perception signal on the second resource through the receiving beam Rx (optionally, the reflection signal can also be called a perception signal), and then reports the perception measurement result. The perception node receives the control information to complete the perception measurement and reporting. Optionally, the symbol of the sensing signal may be an orthogonal frequency division multiplexing (OFDM) symbol, a single carrier or a frequency modulated continuous wave (FMCW) symbol.

The perception device supports a communication perception fusion node or a communication perception fusion mode. In this mode, a device with SEMF and a perception device interact with each other for control and data through a Uu interface, an SL interface, an F1 interface or an NG interface. Optionally, a device with SEMF may be a core network device, a network device or a terminal device, and the perception device may be a network device or a terminal device. Therefore, the device with SEMF and the perception device may also interact with each other through an interface between a network device and a terminal device, an interface between a terminal device and a terminal device, an interface between a core network device and a network device, an interface between a core network device and a terminal device, an interface between a centralized unit and a distributed unit of a network device, such as interacting with each other for control and data. Figure 3The difference between the sensing devices shown is that the control interaction includes both the interaction of communication control information, such as the scheduling information of downlink data, and the interaction of perception control information, such as the configuration information described in the embodiment of the present application. Correspondingly, the data interaction between the device with SEMF and the sensing device also includes both communication data, such as the interaction through the physical downlink shared channel, and perception data, such as the reporting of perception measurement results. In other words, the perception device can communicate with other nodes and perform perception measurements.

In addition, in some embodiments, the control plane (control plan, CP) and user plane (user plan, UP) of the CU can also be separated and implemented by different entities, namely the control plane CU entity (CU-CP entity) and the user plane CU entity (CU-UP entity). In this network architecture, the signaling generated by the CU can be sent to the terminal device through the DU, or the signaling generated by the terminal device can be sent to the CU through the DU. The DU can directly encapsulate the signaling through the protocol layer and transparently transmit it to the terminal device or CU without parsing it. In this network architecture, the CU is divided into a network device on the radio access network (radio access network, RAN) side. In addition, the CU can also be divided as a network device on the core network (core network, CN) side, and the present application does not impose any restrictions on this.

[0122] To facilitate understanding of the embodiments of the present application, some concepts involved in the embodiments of the present application are explained.

[0123] 1. Self-sensing technology

[0124] Self-sensing technology refers to the sensing device sending a sensing signal and receiving the reflected signal of the sensing signal to complete the sensing task. It can be applied to sensing scenarios such as autonomous driving assistance and unmanned aerial vehicle (UAV) tracking. Figure 3 A sensing device supporting a dedicated sensing mode as shown, or Figure 4 The communication fusion perception device or communication device supporting the communication perception fusion mode is shown.

[0125] 2. Perceived Tasks or Perceived Needs

[0126] The perception task or perception requirement may be that the network device or terminal device perceives and identifies a specific area, specific object or event, such as environmental perception, target recognition, target positioning, target imaging, etc. For another example, for smart transportation and UAV, the network device or terminal device can use the wireless frequency band for perception and generate map information. For another example, during the driving process of a vehicle or a drone, for dangerous events such as the sudden appearance of a person or object, the network device or terminal device can use the wireless frequency band to perceive and identify dangerous events. For another example, in the automatic driving assistance of a vehicle or a drone, the network device or terminal device can use the wireless frequency band for perception to obtain a high-precision dynamic map to assist the vehicle or drone in automatic driving. For another example, for illegal driving behaviors, such as vehicles occupying emergency lanes and drones leaving the route, the network device or terminal device can use the wireless frequency band for perception, identify vehicle violations and perform real-time warnings / post-event penalties. For another example, for foreign objects (people, animals, falling rocks, etc.) invading highways and railway tracks, or drones invading no-fly zones (e.g., airports), the network device or terminal device can use the wireless frequency band for perception to identify foreign objects and perform real-time emergency processing. For another example, for home health monitoring scenarios, such as abnormal posture detection such as falling, network devices or terminal devices can use wireless frequency bands to sense, identify abnormal postures and issue alarms. For another example, for health detection such as human breathing / heartbeat, network devices or terminal devices can use wireless frequency bands to sense, identify abnormal indicators and issue alarms. For another example, for meteorological monitoring scenarios, network devices or terminal devices can use wireless frequency bands to sense, detect or predict changes in the environment, climate, and weather.

[0127] 3. Sensing block (SEB)

[0128] The perception block includes a first resource and a second resource. The first resource is a time domain resource for sending a perception signal, including one or more symbols, which can be called a symbol block. The second resource is a time domain resource for monitoring or receiving a reflection signal of the perception signal, which can also include one or more symbols or a predefined time or a configured time, which can also be called a receive window (Rx window). Figure 5 As shown, the first resource included in the perception block is a symbol block corresponding to transmission (Tx), and the second resource is a symbol block corresponding to reception (Rx).

[0129] The configuration information is used to configure the perception block, and the configuration information includes indication information of the first resource and indication information of the second resource. Optionally, the indication information of the first resource may include at least one of a symbol index or a time slot index of the perception signal, and the indication information of the second resource may include a size of a time receiving window for monitoring the reflected signal, and also includes at least one of a symbol index or a time slot index of the receiving time window.

[0130] Optionally, the configuration information includes, in addition to the indication information of the first resource and the indication information of the second resource, the period of the perception block, the number of symbols contained in the perception block, the number of symbols of the perception signal contained in the perception block, the start time of the perception block, whether the perception block contains a synchronous broadcast block, whether the perception block contains a synchronization signal, the subcarrier spacing of the perception signal, the duration of the cyclic prefix (CP) of the symbol of the perception signal, the frequency domain starting position of the perception signal, the bandwidth of the perception signal, the frequency domain starting position of the perception block, the bandwidth of the perception block, a guard period (GP) for transceiver conversion, or at least one of the repetition times of the perception block. Among them, the period of the perception block means that the perception block is periodically configured. When the symbol of the perception signal is an OFDM symbol, the perception signal can be divided into a perception signal with or without CP. For example Figure 5 As shown, if the sensing mode is a half-duplex sensing mode, the sensing block also includes a GP for transceiver conversion. Optionally, the sensing block includes time domain and frequency domain resources of the control channel, such as Figure 5 As shown, control represents the resources occupied by the control channel, and some or all of the parameters in the configuration information can be sent to the sensing device or the receiving device through the control channel.

[0131] The sensing block is used to send and receive sensing signals in a certain direction and a certain distance, or the sensing block is used to send and receive sensing signals in a certain direction and a certain range, or the sensing block is used to send and receive sensing signals in a certain direction, a certain distance and a certain range. The configuration of the sensing block also needs to be combined with the sensing request information to request at least one of the angle range or distance range for sensing, or at least one of the angle range or distance range for sensing and the angle resolution.

[0132] The number of repetitions of the perception block can also be called the repetition factor. The perception device uses the perception block to send and receive perception signals multiple times according to the number of repetitions, which can improve the signal-to-noise ratio and thereby improve the estimation accuracy of the requested perception distance, angle or speed.

[0133] The sensing signal is sent through the Tx beam, and the reflected signal of the sensing signal is received through the Rx beam. Each sensing block corresponds to a Tx beam and an Rx beam, which can be called a beam pair, or the Tx beam and Rx beam of the sensing reference signal (SERS), that is, the Tx beam corresponds to the beam for sending the sensing signal, and the Rx beam corresponds to the beam for receiving the reflected signal of the sensing signal. For the sensing device with integrated transmission and reception, the Tx beam and the Rx beam overlap in time during full-duplex sensing, and the Tx beam and the Rx beam are in a time division multiplexing (TDM) relationship during half-duplex sensing. The Rx beam corresponds to the sensing signal that is monitored for reflection within the Rx time window.

[0134] Optionally, the Tx beams configured by different sensing blocks may be the same, or the Rx beams configured by different sensing blocks may be the same.

[0135] 4. Sensing block set (SEB set)

[0136] The configuration information is used to configure one or more perception block sets, each perception block set includes at least one perception block, and at least one of the following information possessed by the perception blocks in different perception block sets is different: indication information of the first resource, indication information of the second resource, period of the perception block, number of symbols contained in the perception block, number of symbols of the perception signal contained in the perception block, start time of the perception block, whether the perception block contains a synchronous broadcast block, whether the perception block contains a synchronization signal, subcarrier spacing of the perception signal, duration of the cyclic prefix of the symbol of the perception signal, frequency domain start position of the perception signal, bandwidth of the perception signal, frequency domain start position of the perception block, bandwidth of the perception block, protection interval for transceiver conversion or number of repetitions of the perception block. That is, the embodiment of the present application supports different perception block sets and can support different configuration information and transceiver beam pairs, and different perception block sets can determine the configuration information separately. Optionally, at least one perception block in the perception block set can be a perception block on the same frequency band, which can be used for self-perception, or collaborative perception. Figure 5 As shown, multiple perception blocks on the same frequency band constitute a perception block set. The configuration information of the perception blocks in different perception block sets is different, so they are represented by blocks of different formats.

[0137] Different perception block sets have at least one of the following information that is different: a period of the perception block set, a number of perception blocks included in the perception block set, a symbol configuration of each perception block in the perception block set, or an interval between perception blocks in the perception block set. The period of the perception block set means that the perception set including multiple perception blocks is periodically configured.

[0138] Optionally, different perception block sets correspond to different perception request information, and / or different perception blocks in the same perception block set correspond to different perception request information; the perception request information is used to request at least one of the perception angle range or distance range, or to request at least one of the perception angle range or distance range and the angle resolution. In other words, the perception block set can be used to complete one or more perception tasks within a period of time, such as environmental perception, target recognition, target positioning, target imaging, etc. Multiple perception blocks in a perception set within a perception cycle can cover the sending and receiving of perception signals in multiple directions and at different distances required by the perception task.

[0139] For reliability-sensitive perception tasks, the repetition factor of the perception block can be configured to meet the perception accuracy requirements within the perception block set, or the periodic transmission of the perception block or perception block set can be configured to accumulate the received energy to meet the perception accuracy requirements.

[0140] Optionally, the symbol resources and communication resources of each perception block in the perception block set configured by the network device are in a time-division multiplexing relationship, or the network device may configure dedicated resources for the terminal device as resources of the perception block set.

[0141] The transceiver beam pair configuration of each perception block in the perception block set supports fixed Tx beams and polls each Rx beam to obtain the Rx beam corresponding to the Tx beam; or supports fixed Rx beams and polls each Tx beam to obtain the Tx beam corresponding to the Rx beam. In addition, the transceiver beam pair of each perception block in the perception block set is configured for the perception device. The perception device can be a terminal device or a network device. If the perception device is a terminal device, then the transceiver beam pair of each perception block refers to the transceiver beam pair used by the terminal device to send and receive perception signals; if the perception device is a network device, then the transceiver beam pair of each perception block refers to the transceiver beam pair used by the network device to send and receive perception signals.

[0142] 5. Transmit beam and receive beam corresponding to the perception block

[0143] The transmit and receive beam pair of the perception block is determined by the perception device based on configuration information. The configuration information also includes indication information of the reference beam. The transmit beam and / or receive beam is determined based on the reference beam.

[0144] The following describes optional implementations including but not limited to determining a transmit beam and / or receive beam of a perception block based on a reference beam.

[0145] 5.1 The sensing device determines the transmit beam and receive beam of the sensing block according to the indication information of the reference beam.

[0146] In an optional implementation, the reference beam includes one or more first reference beams, the first reference beam is used as a transmit beam, and the receive beam is determined based on beam reciprocity and the corresponding transmit beam. The indication information indicates the one or more first reference beams.

[0147] Optionally, configuration information is sent to a terminal device for the terminal device to perform a self-sensing operation, that is, when the sensing device is a terminal device, the first reference beam may be a beam of an uplink reference signal such as a channel sounding reference signal, a beam of an uplink demodulation reference signal, or a beam of a preamble code. Configuration information is sent to a network device for the network device to perform a self-sensing operation, that is, when the sensing device is a network device, the first reference beam may be a beam of a downlink reference signal such as a synchronization signal or a synchronization broadcast block, a beam of a channel state information reference signal, a beam of a downlink demodulation reference signal, or a beam of a positioning reference signal.

[0148] For example, assuming that sensing block 1 and sensing block 2 are configured for a terminal device, and the reference beam is the beam of a channel sounding reference signal, and the indication information of the reference beam is the index of beam 1 and beam 2 of the channel sounding reference signal, then the transmitting beam of sensing block 1 is beam 1 of the channel sounding reference signal, the transmitting beam of sensing block 2 is beam 2 of the channel sounding reference signal, the receiving beam of sensing block 1 is determined using beam reciprocity and beam 1 of the channel sounding reference signal, and the receiving beam of sensing block 2 is determined using beam reciprocity and beam 2 of the channel sounding reference signal.

[0149] In another optional implementation, the reference beam includes one or more second reference beams, the second reference beam is used as a receiving beam, and the transmitting beam is determined based on beam reciprocity and the corresponding receiving beam. The indication information indicates the one or more second reference beams.

[0150] Optionally, configuration information is sent to a terminal device for the terminal device to perform a self-sensing operation, that is, when the sensing device is a terminal device, the second reference beam may be a beam of a downlink reference signal such as a synchronization signal or a synchronization broadcast block, a beam of a channel state information reference signal, a beam of a downlink demodulation reference signal, or a beam of a positioning reference signal; configuration information is sent to a network device for the network device to perform a self-sensing operation, that is, when the sensing device is a network device, the second reference beam may be a beam of an uplink reference signal such as a beam of a channel sounding reference signal, a beam of an uplink demodulation reference signal, or a beam of a preamble code.

[0151] For example, assuming that perception block 1 and perception block 2 are configured for the terminal device, and the reference beam is the beam of the synchronization signal or the synchronization broadcast block, and the indication information of the reference beam is the index of beam 1 and beam 2 of the synchronization signal or the synchronization broadcast block, then the receiving beam of perception block 1 is beam 1 of the synchronization signal or the synchronization broadcast block, the receiving beam of perception block 2 is beam 2 of the synchronization signal or the synchronization broadcast block, the transmitting beam of perception block 1 is determined using beam reciprocity and beam 1 of the synchronization signal or the synchronization broadcast block, and the transmitting beam of perception block 2 is determined using beam reciprocity and beam 2 of the synchronization signal or the synchronization broadcast block.

[0152] In another optional implementation, the reference beam includes one or more first reference beams and one or more second reference beams, the first reference beam serves as a transmitting beam, and the second reference beam serves as a receiving beam. Optionally, in the case where multiple first reference beams serve as transmitting beams and multiple second reference beams serve as receiving beams, when the sensing device determines the transmit-receive beam pair of the sensing block, it is necessary to scan and pair the Tx beam and the Rx beam according to certain rules for the transmit beam and the receive beam determined based on the reference beam configured by the configuration information. For example, the transmit-receive beam pair of each sensing block can be determined using the polling method described above, such as supporting a fixed Tx beam and polling each Rx beam to obtain an Rx beam corresponding to the Tx beam; or supporting a fixed Rx beam and polling each Tx beam to obtain a Tx beam corresponding to the Rx beam.

[0153] For example, assuming that the indication information indicates four first reference beams as transmitting beams, which are respectively recorded as Tx Beam 0 to Tx Beam 3, and the indication information indicates four second reference beams as receiving beams, which are respectively recorded as Rx Beam 0 to Rx Beam 3, then, the polling configuration can be performed in sequence according to the pairing order of the transmit and receive beam pairs shown in Table 1: Tx Beam 0, Rx Beam 0 of perception block 0; Tx Beam 0, Rx Beam 1 of perception block 1; Tx Beam 0, Rx Beam 2 of perception block 2; Tx Beam 0, Rx Beam 3 of perception block 3; ... until Tx Beam 3, Rx Beam 3 of perception block 15.

[0154] Table 1 Transmitting and receiving beam pair pairing order

[0155] Tx\Rx beam 0 1 2 3 0 0,0 0,1 0,2 0,3 1 1,0 1,1 1,2 1,3 2 2,0 2,1 2,2 2,3 3 3,0 3,1 3,2 3,3

[0156] Optionally, in order to obtain the perception detection results of the corresponding beam direction, the perception detection results of each perception block can be reported in sequence or the index of the perception detection results can be reported in sequence, which is conducive to reducing overhead and avoiding the overhead caused by beam-by-beam indication.

[0157] Optionally, in this implementation, for the non-reciprocal situation, the polling method described above may be used to configure corresponding Tx beams and Rx beams for each sensing block.

[0158] 5.2 The perception device determines the transmit beam of the perception block based on the indication information of the reference beam and other parameters, and then determines the receive beam based on the beam reciprocity and the corresponding transmit beam.

[0159] In an optional implementation, the reference beam includes a first reference beam, the transmit beam includes a first transmit beam, and the first transmit beam is determined based on the first reference beam and an offset of a transmit angle between the first transmit beam and the first reference beam.

[0160] For example, the indication information of the reference beam is the index of beam 1 of SRS, the configuration information also includes that the offset of the transmission angle between the first transmission beam and the first reference beam is 10 degrees, and the configuration information is used to configure a perception block. Then, the perception device can know that the transmission angle of the first reference beam is 30 degrees based on the index of beam 1 of SRS, and based on the offset of the transmission angle between the first transmission beam and the first reference beam is 10 degrees, it can be determined that the first transmission beam of the perception block is a beam with a transmission angle of 40 degrees, and based on beam reciprocity and the first transmission beam, it can be determined that the first receiving beam of the perception block is a beam with a receiving angle of 40 degrees.

[0161] In another optional implementation, the first reference beam is used as the first transmission beam, or the first transmission beam is determined based on the first reference beam and the offset of the transmission angle between the first transmission beam and the first reference beam; the second transmission beam is determined based on at least two of the angle range of the transmission beam, the number of transmission beams, and the interval between different transmission beams in the transmission beam, and the first transmission beam. The reference beam includes the first reference beam, and the transmission beam includes the first transmission beam and the second transmission beam.

[0162] That is to say, in one way, the configuration information includes the indication information of the first reference beam, and also includes at least two items of the angle range, number and interval of different transmission beams of the transmission beam. In addition, it is agreed that the starting transmission beam is the first reference beam. In another way, the configuration information includes the indication information of the first reference beam and the offset of the transmission angle between the starting transmission beam and the first reference beam, and also includes at least two items of the angle range, number and interval of different transmission beams of the transmission beam. In this way, the starting transmission beam is determined based on the first reference beam and the offset. Furthermore, in both ways, the sensing device can determine the remaining transmission beams based on at least two items of the angle range, number and interval of different transmission beams of the transmission beam in the configuration information, combined with the starting transmission beam, and then determine the corresponding receiving beam in combination with the beam reciprocity and the corresponding transmission beam, so as to obtain the transceiver beam pair of each sensing block. Among them, the number of transmission beams can be the number when the number of repetitions of the sensing block and the fixed scanning beam direction are not considered.

[0163] If the offset is equal to 0, the initial transmission beam is the first reference beam; if the offset is greater than 0, the initial transmission beam is the beam with the transmission angle obtained by adding the offset to the transmission angle of the first reference beam or subtracting the offset. For example, see Figure 6 , Figure 6 It is a schematic diagram of determining the starting transmission beam based on the reference beam, such as Figure 6 As shown, if the offset of the transmission angle between the starting transmission beam and the first reference beam in the configuration information is 0, then Figure 6 The first reference beam shown is the starting transmission beam. Based on the beam reciprocity and the starting transmission beam, it can be determined as follows: Figure 6 The starting receiving beam shown; if the offset of the transmission angle between the starting transmitting beam and the first reference beam in the configuration information is greater than 0, then Figure 6 The beam obtained by increasing the offset from the transmission angle of the first reference beam shown is the starting transmission beam. Based on the beam reciprocity and the starting transmission beam, it can be determined as follows: Figure 6 The starting receive beam is shown.

[0164] For example, the configuration information includes the indication information of the first reference beam, which is the index 1 of the beam of the uplink reference signal, and it is agreed that the starting transmission beam is the beam of the uplink reference signal. The configuration information also includes that the angle range of the transmission beam is 60 degrees and the number is 2. In this way, the sensing device can obtain the angle size of each transmission beam as 30 degrees based on the angle range of 60 degrees and the number of 2, and determine the first transmission beam as beam 1 based on the transmission angle of beam 1 of the uplink reference signal, and the second transmission beam as the beam with a 30-degree offset added to the transmission angle of beam 1; then determine each Rx beam based on beam reciprocity and the corresponding first and second transmission beams.

[0165] For another example, the configuration information includes the indication information of the first reference beam, which is the index 1 of the beam of the uplink reference signal, and the offset of the transmission angle between the starting transmission beam and the beam 1 is 30 degrees. The configuration information also includes that the angle range of the transmission beam is 60 degrees and the number is 2. In this way, the sensing device can obtain the angle size of each transmission beam as 30 degrees based on the angle range of 60 degrees and the number of 2, and determine the first transmission beam as the beam with the transmission angle of beam 1 of the uplink reference signal increased by 30 degrees, and the second transmission beam as the beam with the transmission angle of the first transmission beam increased by 30 degrees; and then determine each Rx beam based on beam reciprocity and the corresponding first and second transmission beams.

[0166] Optionally, the configuration information may also include the transmission angle of the first reference beam in the global coordinate system and the coordinate conversion coefficient in the local coordinate system, so as to determine the Tx beam of each perception block by combining at least two of the angle range of the transmission beam, the number of transmission beams and the interval between different transmission beams in the transmission beam in the configuration information. For example, in the above example, the transmission angle of beam 1 of the uplink reference signal can be the transmission angle in the global coordinate system, and then the Tx beam of each transmission angle can be directly obtained based on the above at least two items of information. The transmission angle of beam 1 of the uplink reference signal in the global coordinate system can also be converted into the transmission angle in the local coordinate system in combination with the coordinate conversion coefficient of the local coordinate system in the configuration information, and then the Tx beam of each transmission angle can be obtained based on the above at least two items of information.

[0167] In another optional implementation, the first reference beam is used as the first transmission beam, or the first transmission beam is determined based on the first reference beam and the offset of the transmission angle between the first transmission beam and the first reference beam; the second transmission beam is determined based on the interval or offset of different transmission beams in the transmission beam and in combination with the first transmission beam. The reference beam includes the first reference beam, and the transmission beam includes the first transmission beam and the second transmission beam. The first transmission beam is the starting transmission beam, and the method for determining the starting transmission beam can refer to the relevant explanation in the above implementation, which will not be described in detail here. The difference between this implementation and the above implementation is that other transmission beams can be determined based on the starting transmission beam and the interval or offset of different transmission beams.

[0168] For example, the configuration information includes the indication information of the first reference beam, which is the index 1 of the beam of the uplink reference signal, and it is agreed that the starting transmit beam is the beam of the uplink reference signal. The configuration information also includes that the interval or offset of different transmit beams is 30 degrees, and based on the transmit angle of beam 1 of the uplink reference signal, the first transmit beam is determined to be beam 1, and the second transmit beam is the beam with an offset of 30 degrees added to the transmit angle of beam 1; and then, based on beam reciprocity and the corresponding first transmit beam and second transmit beam, each Rx beam is determined.

[0169] 5.3 The perception device determines the receiving beam of the perception block based on the indication information of the reference beam and other parameters, and then determines the transmitting beam based on the beam reciprocity and the corresponding receiving beam.

[0170] In an optional implementation, the reference beam includes a second reference beam, the receiving beam includes a first receiving beam, and the first receiving beam is determined based on the second reference beam and an offset of a receiving angle between the first receiving beam and the second reference beam.

[0171] For example, the indication information of the reference beam is the index of beam 1 of the SSB, the configuration information also includes that the offset of the receiving angle between the first receiving beam and the second reference beam is 10 degrees, and the configuration information is used to configure a perception block. Then, the perception device can know that the transmitting angle of the second reference beam is 30 degrees based on the index of beam 1 of the SSB, and based on the offset of the receiving angle between the first receiving beam and the second reference beam is 10 degrees, it can be determined that the first receiving beam of the perception block is a beam with a receiving angle of 40 degrees, and based on the beam reciprocity and the first receiving beam, it can be determined that the first transmitting beam of the perception block is a beam with a transmitting angle of 40 degrees.

[0172] In another optional implementation, the second reference beam is used as the first receiving beam, or the first receiving beam is determined based on the second reference beam and the offset of the receiving angle between the first receiving beam and the second reference beam; the second receiving beam is determined based on at least two of the angle range of the receiving beam, the number of receiving beams, and the interval between different receiving beams in the receiving beam, and the first receiving beam. The reference beam includes the second reference beam, and the receiving beam includes the first receiving beam and the second receiving beam.

[0173] That is to say, in one way, the configuration information includes the indication information of the second reference beam, and also includes at least two items of the angle range, number and interval of different receiving beams of the receiving beam. In addition, it is agreed that the starting receiving beam is the second reference beam. In another way, the configuration information includes the indication information of the second reference beam and the offset of the receiving angle between the starting receiving beam and the second reference beam, and also includes at least two items of the angle range, number and interval of different receiving beams of the receiving beam. In this way, the starting receiving beam is determined based on the second reference beam and the offset. Furthermore, in both ways, the sensing device can determine the remaining receiving beams based on at least two items of the angle range, number and interval of different receiving beams of the receiving beam in the configuration information, combined with the starting receiving beam, and then determine the corresponding transmitting beam in combination with the beam reciprocity and the corresponding receiving beam, so as to obtain the transmitting and receiving beam pairs of each sensing block. Among them, the number of receiving beams can be the number when the number of repetitions of the sensing block and the fixed scanning beam direction are not considered.

[0174] If the offset is equal to 0, the starting receiving beam is the first reference beam; if the offset is greater than 0, the starting receiving beam is the receiving angle of the second reference beam plus the offset or minus the offset. Figure 7 , Figure 7 is a schematic diagram of determining the starting receiving beam based on the reference beam, such as Figure 7 As shown, if the offset of the receiving angle between the starting receiving beam and the second reference beam in the configuration information is 0, then Figure 7The second reference beam shown is the starting receiving beam. Based on the beam reciprocity and the starting receiving beam, it can be determined as follows: Figure 7 The starting transmission beam shown; if the offset of the receiving angle between the starting receiving beam and the second reference beam in the configuration information is greater than 0, then Figure 7 The receiving angle of the second reference beam shown in FIG. 1 is increased by the offset to obtain a beam as the starting receiving beam. Based on the beam reciprocity and the starting receiving beam, it can be determined as follows: Figure 7 The starting transmit beam is shown.

[0175] For example, the configuration information includes the indication information of the second reference beam, which is the index 1 of the beam of the downlink reference signal, and stipulates that the starting receiving beam is the beam of the downlink reference signal. The configuration information also includes that the angle range of the receiving beam is 60 degrees and the number is 2. In this way, the sensing device can obtain the angle size of each receiving beam as 30 degrees based on the angle range of 60 degrees and the number of 2, and determine the first receiving beam as beam 1 based on the receiving angle of beam 1 of the downlink reference signal, and the second receiving beam as the beam with an increase of 30 degrees offset from the receiving angle of beam 1; then determine each Tx beam based on beam reciprocity and the corresponding first receiving beam and second receiving beam.

[0176] For another example, the configuration information includes the indication information of the second reference beam, which is the index 1 of the beam of the downlink reference signal, and the offset of the receiving angle between the starting receiving beam and the beam 1 is 30 degrees. The configuration information also includes that the angle range of the receiving beam is 60 degrees and the number is 2. In this way, the sensing device can obtain the angle size of each receiving beam as 30 degrees based on the angle range of 60 degrees and the number of 2, and determine the first receiving beam as the beam with the transmission angle of beam 1 of the downlink reference signal increased by 30 degrees, and the second receiving beam as the beam with the receiving angle of the first receiving beam increased by 30 degrees. The receiving beam is then determined based on beam reciprocity and the corresponding first receiving beam and second receiving beam.

[0177] Optionally, the configuration information may also include the receiving angle of the second reference beam in the global coordinate system and the coordinate conversion coefficient in the local coordinate system, so as to determine the Rx beam of each perception block by combining at least two of the angle range of the receiving beam, the number of receiving beams, and the interval between different receiving beams in the receiving beam in the configuration information. For example, in the above example, the receiving angle of beam 1 of the downlink reference signal can be the receiving angle in the global coordinate system, and then the Tx beam of each receiving angle can be directly obtained based on the above at least two items of information. The receiving angle of beam 1 of the uplink reference signal in the global coordinate system can also be converted into the receiving angle in the local coordinate system in combination with the coordinate conversion coefficient of the local coordinate system in the configuration information, and then the Rx beam of each receiving angle can be obtained based on the above at least two items of information.

[0178] In another optional embodiment, the second reference beam is used as the first receiving beam, or the first receiving beam is determined based on the second reference beam and the offset of the transmission angle between the first receiving beam and the second reference beam; the second receiving beam is determined based on the interval or offset of different receiving beams in the receiving beam, in combination with the first receiving beam. The reference beam includes the second reference beam, and the receiving beam includes the first receiving beam and the second receiving beam. The first receiving beam is the starting receiving beam, and the method for determining the starting receiving beam can refer to the relevant description in the above embodiment, which will not be described in detail here. The difference between this embodiment and the above embodiment is that other receiving beams can be determined based on the starting receiving beam and the interval or offset of different receiving beams.

[0179] For example, the configuration information includes the indication information of the second reference beam, which is the index 1 of the beam of the downlink reference signal, and it is agreed that the starting receiving beam is the beam of the downlink reference signal. The configuration information also includes that the interval or offset of different receiving beams is 30 degrees, and based on the receiving angle of beam 1 of the downlink reference signal, the first receiving beam is determined to be beam 1, and the second receiving beam is the beam with an offset of 30 degrees added to the receiving angle of beam 1; and then based on the beam reciprocity and the corresponding first receiving beam and second receiving beam, each Tx beam is determined.

[0180] 5.4 The sensing device determines the receiving beam and transmitting beam of the sensing block according to the indication information of the reference beam and other parameters.

[0181] The implementation method of this part is different from the above implementation method in that, in the implementation method of this part, the transmit and receive beam pairs are not determined by beam reciprocity. In the case of non-reciprocity, for the determined receive beam and transmit beam, beam scanning pairing is required. For example, according to the indication information of the reference beam and other parameters, m transmit beams and n receive beams are determined, and based on the predefined beam scanning rules, the configuration method described in Table 1 above is used to perform beam polling configuration for each perception block. In which, m and n are both integers greater than or equal to 1, m represents the number of transmit beams (Tx beams), and n represents the number of receive beams (Rx beams).

[0182] The following describes the optional implementation methods of determining the receiving beam and transmitting beam of the perception block based on the indication information of the reference beam and other parameters.

[0183] In an optional implementation, the first transmit beam is determined based on the first reference beam and the offset of the receiving angle between the first transmit beam and the first reference beam, and the first receive beam is determined based on the second reference beam and the offset of the receiving angle between the first receive beam and the second reference beam. The reference beam includes the first reference beam and the second reference beam, the transmit beam includes the first transmit beam, and the receive beam includes the first receive beam.

[0184] In another optional implementation, the first reference beam serves as the first transmit beam, or the first transmit beam is determined based on the first reference beam and the offset of the transmit angle between the first transmit beam and the first reference beam; the second transmit beam is determined based on the interval or offset of different transmit beams in the transmit beam, combined with the first transmit beam. The second reference beam serves as the first receive beam, or the first receive beam is determined based on the second reference beam and the offset of the receive angle between the first receive beam and the second reference beam; the second receive beam is determined based on the interval or offset of different receive beams in the receive beam, combined with the first receive beam. Wherein, the reference beam includes the first reference beam and the second reference beam, the transmit beam includes the first transmit beam and the second transmit beam, and the receive beam includes the first receive beam and the second beam.

[0185] That is, in this implementation, the configuration information includes not only the indication information of the reference beam, but also the intervals or offsets of different transmit beams, and the intervals or offsets of different receive beams. The starting transmit beam and the starting receive beam are determined based on the reference beam, and other transmit beams and other receive beams are determined based on the starting transmit beam and the starting receive beam, respectively, in combination with the intervals or offsets of different transmit beams, and the intervals or offsets of different receive beams.

[0186] For example, in the configuration information, the indication information of the first reference beam is the index 1-1 of the beam of the uplink reference signal, and the indication information of the second reference beam is the index 2-1 of the beam of the downlink reference signal, and it is agreed that the starting transmitting beam is beam 1-1 of the uplink reference signal, and the starting receiving beam is beam 2-1 of the downlink reference signal. The configuration information also includes that the angle range of the transmitting beam is 60 degrees and the number is 2, and the angle range of the receiving beam is 60 degrees and the number is 2. In this way, the perception device can obtain the angular size of each transmitting beam as 30 degrees based on the angle range of 60 degrees and the number of 2, and use the transmission angle of beam 1-1 of the uplink reference signal as a reference to determine that the first transmitting beam is beam 1-1, and the second transmitting beam is a beam with a 30-degree offset increase from the transmission angle of beam 1-1; the perception device can obtain the angular size of each receiving beam as 30 degrees based on the angle range of 60 degrees and the number of 2, and use the receiving angle of beam 2-1 of the downlink reference signal as a reference to determine that the first receiving beam is beam 2-1, and the second receiving beam is a beam with a 30-degree offset increase from the receiving angle of beam 2-1.

[0187] In another optional embodiment, the first reference beam is used as the first transmission beam, or the first transmission beam is determined based on the first reference beam and the offset of the transmission angle between the first transmission beam and the first reference beam; the second transmission beam is determined based on at least two of the angle range of the transmission beam, the number of transmission beams, and the interval between different transmission beams in the transmission beam, and the first transmission beam. The second reference beam is used as the first receiving beam, or the first receiving beam is determined based on the second reference beam and the offset of the reception angle between the first receiving beam and the second reference beam; the second receiving beam is determined based on at least two of the angle range of the receiving beam, the number of receiving beams, and the interval between different receiving beams in the receiving beam, and the first receiving beam. Wherein, the reference beam includes the first reference beam and the second reference beam, the transmission beam includes the first transmission beam and the second transmission beam, and the receiving beam includes the first receiving beam and the second receiving beam.

[0188] That is, in this embodiment, in addition to the indication information of the beam of the uplink reference signal and the indication information of the beam of the downlink reference signal, the configuration information also includes at least two of the angle range of the transmission beam, the number of transmission beams, and the interval between different transmission beams in the transmission beam, and at least two of the angle range of the reception beam, the number of reception beams, and the interval between different reception beams in the reception beam. The starting transmission beam and the starting reception beam are determined based on the reference beam, and other transmission beams and other reception beams are determined based on the starting transmission beam and the starting reception beam, respectively, in combination with other parameters.

[0189] Optionally, the indication information of the reference beam in the configuration information is a downlink reference signal, such as SSB, CSIRS or downlink DMRS, etc. The second device can determine the spatial relationship or beam of the receiving beam of the perception signal based on the reference signal, and then determine the spatial relationship or the transmitting beam of the transmitting beam based on the spatial relationship of the receiving beam or the receiving beam. Optionally, the indication information of the reference beam in the configuration information is an uplink reference signal, such as SRS or uplink DMRS or preamble, etc. The second device can determine the spatial relationship or the transmitting beam of the transmitting beam of the perception signal based on the reference signal, and then determine the spatial relationship or the receiving beam of the receiving beam based on the spatial relationship of the transmitting beam or the transmitting beam.

[0190] Optionally, in an embodiment of the present application, the second device determines a receiving beam and / or a transmitting beam based on a reference beam, or may use the reference beam as a receiving beam and / or a transmitting beam as described in an embodiment of the present application, or, in addition to determining the transmitting beam and / or the receiving beam based on the transmitting angle and / or receiving angle of the reference beam combined with an offset, may also determine the transmitting beam and / or the receiving beam based on the spatial relationship of the reference beam, or determine the spatial relationship of the transmitting beam and / or the receiving beam based on the spatial relationship of the reference beam, or determine the spatial relationship of the transmitting beam and / or the receiving beam using the reference beam.

[0191] Optionally, the case where the transmit beam is determined based on beam reciprocity and the corresponding receive beam can be replaced by: the transmit beam is determined based on the spatial relationship of the corresponding receive beam, or the spatial relationship of the transmit beam is determined based on the spatial relationship of the corresponding receive beam, or the spatial relationship of the transmit beam is determined based on the corresponding receive beam. Optionally, the case where the receive beam is determined based on beam reciprocity and the corresponding transmit beam can be replaced by: the receive beam is determined based on the spatial relationship of the corresponding transmit beam, or the spatial relationship of the receive beam is determined based on the spatial relationship of the corresponding transmit beam, or the spatial relationship of the receive beam is determined based on the corresponding transmit beam.

[0192] In the present application, the reciprocity between the transmitting beam and the receiving beam, or the determination of one beam by another beam, or the spatial relationship of one signal by another signal, or the spatial relationship of one signal by another signal, or the spatial relationship of one signal by another signal, or the spatial characteristic of one signal by another signal, or the spatial filter of one signal by another signal, may refer to: the spatial relationship (or spatial characteristic or spatial filter) of the transmitting signals is determined according to the receiving signals, or the spatial relationship (or spatial characteristic or spatial filter) of the receiving signals is determined according to the transmitting signals, or the spatial relationship (or spatial characteristic or spatial filter) of the transmitting signals is determined according to the spatial relationship (or spatial characteristic or spatial filter) of the receiving signals, or the spatial relationship (or spatial characteristic or spatial filter) of the receiving signals is determined according to the spatial relationship (or spatial characteristic or spatial filter) of the transmitting signals, or the transmitting beam is determined according to the receiving beam, or the receiving beam is determined according to the transmitting beam.

[0193] Combined with the above description, the relevant process of the perception configuration method is explained.

[0194] See also Figure 8 , Figure 8 : is a flow chart of a perception configuration method provided in an embodiment of the present application. Figure 8 The sensing configuration method shown is described by taking the first device having a SEMF and the second device as a sensing device as an example. Figure 8 As shown, the perception configuration method includes but is not limited to the following steps:

[0195] S101. The first device determines configuration information;

[0196] As described above, the configuration information is used to configure the perception block, the perception block includes a first resource and a second resource, the first resource is used to transmit a perception signal, the perception signal is sent through a transmitting beam, and the second resource is used to monitor a reflected signal of the perception signal, and the reflected signal is received through a receiving beam.

[0197] In addition, the configuration information needs to include indication information of the reference beam, or needs to include indication information of the reference beam and other parameters. Other parameters may include at least two of the starting transmit beam or the offset of the transmit angle between the starting transmit beam and the reference beam, the angular range of the transmit beam, the number of transmit beams, and the interval between different transmit beams in the transmit beam, or include the interval or offset of different transmit beams. Alternatively, other parameters may include at least two of the starting receive beam or the offset of the receive angle between the starting receive beam and the reference beam, the angular range of the receive beam, the number of receive beams, and the interval between different receive beams in the receive beam, or include the interval or offset of different receive beams. Alternatively, other parameters may include at least two of the starting transmit beam or the offset of the transmit angle between the starting transmit beam and the reference beam, the angular range of the transmit beam, the number of transmit beams, and the interval between different transmit beams in the transmit beam, or include the interval or offset of different transmit beams; and at least two of the starting receive beam or the offset of the receive angle between the starting receive beam and the reference beam, the angular range of the receive beam, the number of receive beams, and the interval between different receive beams in the receive beam, or include the interval or offset of different receive beams.

[0198] Optionally, the relevant contents of the configuration information can be found in the above-mentioned perception block, perception block set, and the transmit beam and receive beam parts of the perception block, which will not be described in detail here.

[0199] In an optional implementation manner, before the first device determines the configuration information, Figure 8 As shown, it may also include: the first device receives second perception request information from the third device, or the second perception request information triggered by the first device. The second perception request information is used to request at least one of the angle range or distance range of perception, or to request at least one of the angle range or distance range of perception and the angle resolution. Optionally, the second perception request information is also called perception requirement information, and the third device may determine at least one of the angle range or distance range to be requested for perception, or to request at least one of the angle range or distance range and the angle resolution based on the perception task or perception requirement from the application function network element.

[0200] Optionally, the second perception request information may come from a core network device, an access network device or a terminal device. In this embodiment, the first device may determine the configuration information based on the second perception request information. For example, the first device determines the reference beam for the self-perception requirement of a certain target direction. Optionally, the first device may also determine other information in the configuration information. For example, the first device determines at least two of the angle range of the transmitted beam, the number of transmitted beams, and the intervals between different transmitted beams based on at least one of the angle range or distance range for requesting perception, or at least one of the angle range or distance range for requesting perception and the angle resolution, using the second perception request information. For another example, the first device determines at least two of the angle range of the received beam, the number of received beams, and the intervals between different received beams based on at least one of the angle range or distance range for requesting perception, or at least one of the angle range or distance range for requesting perception and the angle resolution, using the second perception request information. For another example, the first device determines at least two of the angular range of the transmitting beam, the number of transmitting beams, and the intervals between different transmitting beams, and determines at least two of the angular range of the receiving beam, the number of receiving beams, and the intervals between different receiving beams based on at least one of the angular range or distance range for requesting perception, or at least one of the angular range or distance range for requesting perception and the angular resolution.

[0201] In another optional implementation, if Figure 8As shown, the first device may also send a sensing capability request message to the second device, and the sensing capability request message is used to request the sensing capability of the second device. Accordingly, the second device receives the sensing capability request message, and the second device sends the sensing capability information of the second device to the first device. Then, the first device determines the configuration information according to the sensing capability information of the second device. Optionally, the sensing capability request message may include a request for whether the second device has duplex capability or half-duplex capability, and accordingly, the sensing capability information may include information for indicating that the second device has duplex capability or half-duplex capability. Among them, whether the second device has duplex capability or half-duplex capability affects the configuration of the second resource in the configuration information. Optionally, the duplex capability is called full-duplex sensing capability, and the half-duplex capability is called half-duplex sensing capability. Among them, when the second device has full-duplex perception capability, the Tx beam and the Rx beam overlap in time, and when the second device has half-duplex perception capability, the Tx beam and the Rx beam are in a time division multiplexing relationship, and the perception block has a time interval for transceiver conversion, and the Rx beam corresponds to the second resource (i.e., within the receiving time window) to monitor the reflected perception signal (i.e., the reflected signal of the transmitted perception signal). Therefore, the half-duplex perception capability and the full-duplex perception capability of the second device affect the start time of the second resource in the configuration information. Optionally, the second device has full-duplex perception capability, and the start time of the first resource in the configuration information is the same as the start time of the second resource; the second device has half-duplex perception capability, and the start time of the second resource in the configuration information is after the time interval for transceiver conversion. Optionally, the length of the time domain resource of the second resource depends on the distance range requested for perception by the perception request information.

[0202] Optionally, the first device may obtain the beam of the channel sounding reference signal transmitted by the second device under line-of-sight transmission based on previous downlink or uplink communication, and then determine the reference beam. If the first device does not obtain the beam of the channel sounding reference signal transmitted by the second device under line-of-sight transmission, it is also necessary to carry indication information in the perception capability request information to trigger the second device to send the channel sounding reference signal and provide feedback on the sending angle of the channel sounding reference signal. Among them, the second device may carry the sending angle of the channel sounding reference signal in the perception capability information. Optionally, as described above, the sending angle can be converted into a sending angle in a global coordinate system.

[0203] In another optional implementation, the first device needs to determine the configuration information based on the perception capability information of the second device and the second perception request information from the third device. For example, the first device determines the perception block configured by the configuration information, as well as the indication information of the reference signal for determining the transmit beam and / or receive beam of the perception block or the indication information of the reference signal for determining the transmit beam and / or receive beam of the perception block and the other parameters described above (not described in detail here) based on whether the second device has duplex capability or half-duplex capability, at least one of the angle range or distance range for requesting perception in the second perception request information, or at least one of the angle range or distance range for requesting perception and the angle resolution.

[0204] Optionally, assuming that the number of Tx beams corresponding to the perception signal is m, and the number of Rx beams is n, for the case of using beam reciprocity to determine the Tx beam or Rx beam, m=n, and the configuration information needs to configure m perception blocks; for the case of using non-beam reciprocity to determine the Tx beam and Rx beam, the configuration information needs to include the configuration of m*n perception blocks, and use the above-mentioned beam polling rule to determine the Tx beam and Rx beam corresponding to each perception block.

[0205] S102. The first device sends configuration information to the second device, and correspondingly, the second device receives the configuration information.

[0206] Optionally, the time domain resources, frequency domain resources and beam resources of the sensing block can be configured by radio resource control (RRC) signaling, media access channel control element (MAC CE) signaling, downlink control information (DCI) or sidelink control information (SCI) signaling. These signalings can be cell-level signaling, group-level signaling or specific terminal-level signaling.

[0207] Optionally, the time domain resources, frequency domain resources and beam resources of the perception blocks included in the perception block set may also be configured by RRC signaling, MAC CE signaling, DCI or SCI signaling. These signaling may be cell-level signaling, group-level signaling or specific terminal-level signaling.

[0208] For example, for a periodic perception block set configuration, the first device may use RRC signaling, such as using a bitmap corresponding to 40 bits to indicate 40 perception blocks or symbol blocks, wherein the number of symbol blocks or perception blocks that the bitmap can indicate may correspond to the maximum number of perception blocks contained in the perception block set. Each bit in the bitmap corresponds to a symbol block, and 40 bits may be used to selectively activate certain symbol blocks among the 40 symbol blocks of the perception block set as activated perception blocks. Optionally, the symbol blocks or perception blocks activated in the perception block set may also be activated through MAC CE activation or DCI or SCI. For a non-periodic perception block set configuration, the first device may indicate the perception blocks or symbol blocks of the perception block set that are finally activated or to be used through DCI or SCI.

[0209] For periodic perception block set configuration, the first device may also configure the start symbol and period of the perception block set. The period may be 5ms, 10ms, 20ms, 40ms, etc.

[0210] Optionally, the number of symbols contained in each symbol block or perception block is configurable or predefined. Optionally, the number of perception blocks contained in the perception block set can be predefined, such as associated with the carrier frequency, and different carrier frequencies correspond to different maximum number of perception blocks and perception block positions of the perception block set.

[0211] S103. The second device sends a perception signal on the first resource by sending a beam, and monitors a reflected signal on the second resource by receiving a beam.

[0212] Optionally, the second device determines the first resource used by the Tx beam of each perception block and the second resource used by the Rx beam according to the configuration information. The method for determining the Tx beam and Rx beam of each perception block can be found in the optional implementation methods described in sections 5.1 to 5.3 of the concept description, which will not be described in detail here. Optionally, for the case where the configuration information is used to configure multiple perception blocks and the transmit and receive beam pairs corresponding to each perception block, in step S103, the second device can use each perception block to scan the Tx beam and the Rx beam.

[0213] Optionally, after step S103, the second device may send the perception measurement result to the first device, and the first device determines the perception response information corresponding to the second perception request information according to the perception measurement result, and then sends the perception response information to the third device. Optionally, the second device may agree with the first device to report the perception measurement results in sequence according to the index of the received beam to avoid the overhead caused by indicating the beam index when reporting the perception measurement result.

[0214] In an optional implementation, Figure 8In the perception configuration method shown, the first device is a network device, the second device is a terminal device, and the third device is a core network device. The network device has a perception management function and sends configuration information to the terminal device, and the terminal device performs related self-perception operations based on the configuration information.

[0215] In another optional embodiment, Figure 8 In the perception configuration method shown, the first device is a core network device, the second device is a network device, and the third device is an application function network element. The core network device has a perception management function and sends configuration information to the network device, and the network device performs self-perception related operations based on the configuration information. The core network device sends configuration information to the network device, which can be sent through the NRPPa interface.

[0216] In another optional embodiment, Figure 8 In the perception configuration method shown, the first device is a core network device, the second device is a terminal device, and the third device is an application function network element. The core network device has a perception management function and sends configuration information to the terminal device, and the terminal device performs self-perception related operations based on the configuration information. The configuration information sent by the core network device to the terminal device can be sent via LPP.

[0217] In the above two implementations, the core network device has a perception management function, and the perception block used for self-perception by the network device or the terminal device can be configured by the core network device. Since the core network device can know the antenna direction of the network device, compared with configuring the transmit beam and / or receive beam of the perception block for the terminal device, the transmit beam and / or receive beam of the perception block configured by the core network device for the network device can be indicated with a finer granularity, such as the horizontal direction angle or the vertical direction angle can be configured with a granularity of 1 degree or 0.1 degree.

[0218] visible, Figure 8 In the perception configuration method shown, the first device can configure a perception block for the second device, so that the second device can use the perception block to perform self-perception related operations.

[0219] See also Fig. 9 , Fig. 9 It is a flow chart of another perception configuration method provided in an embodiment of the present application. Fig. 9 The perception configuration method shown is similar to Figure 8 The difference of the perception configuration method shown is that the second device has a SEMF, and the second device can send a configuration request message to the first device, and the configuration request message is used to request the configuration of the perception block. Fig. 9 As shown, the perception configuration method may include:

[0220] S201. The second device sends configuration request information to the first device. Correspondingly, the first device receives the configuration request information, where the configuration request information is used to request configuration of the perception block.

[0221] Optionally, the configuration request information may include relevant information of the perception block requested for configuration, such as the first resource and the second resource mentioned above, or may also include at least one of the following information: the period of the perception block, the subcarrier spacing of the perception signal, the duration of the cyclic prefix (CP) of the symbol of the perception signal, the guard period (GP) used for transmit-receive conversion, or the number of repetitions of the perception block.

[0222] The configuration request information also includes a reference beam of the starting transmit beam requested to be configured or an offset of the transmit angle between the starting transmit beam and the reference beam, at least two of the angular range of the transmit beam requested to be configured, the number of transmit beams, and the interval between different transmit beams in the transmit beam, or includes the interval or offset of different transmit beams; or also includes a reference beam of the starting receive beam requested to be configured or an offset of the receive angle between the starting receive beam and the reference beam, at least two of the angular range of the receive beam requested to be configured, the number of receive beams, and the interval between different receive beams in the receive beam, or includes the interval of different receive beams. Or offset; or also includes a reference beam of the starting transmitting beam requested to be configured or an offset of the transmitting angle between the starting transmitting beam and the reference beam, at least two of the angular range of the transmitting beam requested to be configured, the number of transmitting beams, and the interval between different transmitting beams in the transmitting beam, or includes the interval or offset of different transmitting beams, and a reference beam of the starting receiving beam requested to be configured or an offset of the receiving angle between the starting receiving beam and the reference beam, at least two of the angular range of the receiving beam requested to be configured, the number of receiving beams, and the interval between different receiving beams in the receiving beam, or includes the interval or offset of different receiving beams.

[0223] In an optional implementation, before step S201, the second device may also receive first perception request information from the first device, and the first perception request information is used to request at least one of the angle range or distance range of perception, or to request at least one of the angle range or distance range of perception and the angle resolution; accordingly, the second device receives the first perception request information, and then determines the configuration request information based on the first perception request information. It can be seen that the second device can receive the perception request information from the first device, and the second device determines the required amount of transceiver beam resources, such as determining the resource requirements of the transmitting beam and the receiving beam for self-perception measurement based on the angle range requested for perception by the perception request information (such as the beams are uniformly distributed within the angle range), and then sending the configuration request information to the first device to request the configuration of the perception block or each perception block in the perception block set.

[0224] For example, the second device determines at least two of the angle range of the transmission beam requested by the configuration request information, the number of transmission beams, or the interval between different transmission beams based on at least one of the angle range or distance range for requesting perception, or at least one of the angle range or distance range for requesting perception and the angle resolution of the first perception request information. For another example, the second device determines at least two of the angle range of the reception beam requested by the configuration request information, the number of reception beams, or the interval between different reception beams based on at least one of the angle range or distance range for requesting perception, or at least one of the angle range or distance range for requesting perception and the angle resolution of the first perception request information. For another example, the second device determines at least two of the angle range of the transmission beam requested by the configuration request information, the number of transmission beams, or the interval between different transmission beams, and at least two of the angle range of the reception beam requested, the number of reception beams, or the interval between different reception beams, based on at least one of the angle range or distance range for requesting perception, or at least one of the angle range or distance range for requesting perception and the angle resolution of the first perception request information.

[0225] Optional, such as Fig. 9 As shown, the first device may receive the second perception request information from the third device, and then send the first perception request information to the second device based on the second perception request information. The first perception request information may be the same as or different from the second perception request information.

[0226] In an optional implementation, the second device calculates at least two of the number, angle range or interval of the required Tx and Rx beams based on the first perception request information of the first device and the perception capability information of the second device, such as antenna configuration and supported angle resolution. Then, the second device sends these configuration request information to the first device.

[0227] In another optional implementation, before step S201, the first device sends a sensing capability request message to the second device, the sensing capability request message is used to request the sensing capability of the second device, and accordingly, the second device receives the sensing capability request message, and the second device sends the sensing capability information of the second device to the first device, and then, the first device sends the first sensing request information to the second device according to the sensing capability information of the second device. In this way, the second device performs the above-mentioned operation of determining the configuration request information according to the first sensing request information.

[0228] S202. The first device determines configuration information according to the configuration request information, where the configuration information is used to configure the perception block.

[0229] In an optional implementation, the first device requests relevant information of the perception block to be configured according to the configuration request information, such as the first resource and the second resource described above, or further requests to configure at least one of the following information: the period of the perception block, the subcarrier spacing of the perception signal, the number of symbols contained in the perception block, the start time of the perception block, whether the perception block contains a synchronous broadcast block, whether the perception block contains a synchronization signal, the duration of the cyclic prefix (CP) of the symbol of the perception signal, the frequency domain starting position of the perception signal, the bandwidth of the perception signal, the frequency domain starting position of the perception block, the bandwidth of the perception block, the guard period (GP) used for transmit-receive conversion, or the number of repetitions of the perception block, to determine the parameters of the perception block in the configuration information.And, the first device determines the relevant parameters of the transmit-receive beam pair in the configuration information according to the reference beam of the starting transmit beam configured by the configuration request information or the offset of the transmit angle between the starting transmit beam and the reference beam; or, the first device determines the relevant parameters of the transmit-receive beam pair in the configuration information according to the reference beam of the starting transmit beam configured by the configuration request information or the offset of the transmit angle between the starting transmit beam and the reference beam, and at least two of the angle range of the transmit beam requested to be configured, the number of transmit beams, and the interval between different transmit beams in the transmit beam; or, the first device determines the relevant parameters of the transmit-receive beam pair in the configuration information according to the reference beam of the starting transmit beam configured by the configuration request information or the offset of the transmit angle between the starting transmit beam and the reference beam. The first device determines the relevant parameters of the transmit-receive beam pair in the configuration information based on the reference beam of the starting transmit beam requested to be configured or the offset of the transmit angle between the starting transmit beam and the reference beam, as well as the interval or offset of different transmit beams requested to be configured; or, the first device determines the relevant parameters of the transmit-receive beam pair in the configuration information based on the reference beam of the starting receive beam requested to be configured or the offset of the receive angle between the starting receive beam and the reference beam, as well as the interval or offset of different transmit beams requested to be configured; or, the first device determines the relevant parameters of the transmit-receive beam pair in the configuration information based on the reference beam of the starting receive beam requested to be configured or the offset of the receive angle between the starting receive beam and the reference beam, as well as the interval or offset of different transmit beams requested to be configured The first device determines the relevant parameters of the transmit-receive beam pair in the configuration information based on at least two of the configured angular range of the receive beam, the number of receive beams, or the interval between different receive beams in the receive beam; or, the first device determines the relevant parameters of the transmit-receive beam pair in the configuration information based on a reference beam of the starting receive beam configured according to the configuration request information or the offset of the receiving angle between the starting receive beam and the reference beam, and the interval or offset of different receive beams requested to be configured; or, the first device determines the relevant parameters of the transmit-receive beam pair in the configuration information based on the relevant parameters of the above-mentioned transmit beam configured according to the configuration request information, such as the reference beam of the starting transmit beam or the offset of the receiving angle between the starting transmit beam and the reference beam. Determine the relevant parameters of the transmit and receive beam pairs in the configuration information by considering the offset of the transmit angles between the transmit beams, such as at least two of the angle range of the transmit beams requested to be configured, the number of transmit beams, or the interval between different transmit beams in the transmit beams, and the interval or offset between different transmit beams, as well as the relevant parameters of the above-mentioned receive beams requested to be configured, such as the reference beam of the starting receive beam or the offset of the receive angle between the starting receive beam and the reference beam, such as at least two of the angle range of the receive beams requested to be configured, the number of receive beams, or the interval between different receive beams in the receive beams, and the interval or offset between different receive beams.

[0230] In another optional implementation, the first device determines configuration information according to the configuration request information, including: the first device determines configuration information of m*n sensing blocks for beam scanning pairing according to the m Tx beams and n Rx beams requested to be configured by the second device in the configuration request information. Optionally, the first device may coordinate potential interference resources and the beam configuration expected to be used by the second device according to the available resources of the system, and perform resource configuration of the Tx and Rx beam pairs for the second device.

[0231] Optionally, the first device determines configuration information according to the configuration request information, including: the first device determines configuration information of m sensing blocks for beam scanning pairing according to the m Tx beams and beam reciprocity beams requested to be configured by the second device in the configuration request information as Rx beams. Optionally, the first device may coordinate potential interference resources and the beam configuration expected to be used by the second device according to the available resources of the system, and perform resource configuration of the Tx and Rx beam pairs for the second device.

[0232] For example, in one possible implementation, the second device determines that the Rx beam of the reflected signal of the perception signal is SSB beam 1 to SSB beam 3, takes its reciprocal beam as the Tx beam of the perception signal, and uses these Tx beams and Rx beams as candidate beams for beam scanning and pairing. The second device then requests the required Tx beam and Rx beam pair resources from the first device, that is, there are 3 perception blocks.

[0233] It can be seen that in this implementation, the second device determines the resource requirements, such as the transmit and receive beam pairs that meet the perception requirements, and sends configuration request information to the first device. The first device configures the relevant information of the perception block, which can avoid the overhead required for the beam indication in the configuration information.

[0234] S203. The first device sends configuration information to the second device, and correspondingly, the second device receives the configuration information.

[0235] S204. The second device sends a perception signal on the first resource by using a sending beam, and monitors a reflected signal on the second resource by using a receiving beam.

[0236] Optionally, the second device performs perception measurement according to the m*n perception blocks configured for beam scanning pairing according to the configuration information, and feeds back the perception measurement results according to the requirement configuration of the first device, or performs perception calculation based on the measurement results and sends the perception measurement results to the first device.

[0237] It can be seen that in this method, the first device can be configured with a perception block, which enables the second device to perform self-perception operations using the perception block.

[0238] In another embodiment, the first device may be a network device, and the network device determines configuration information and sends the configuration information to the bottom layer, and configures a perception block for itself, so as to facilitate the network device to use the perception block to perform self-perception operations. Optionally, when the network device configures a perception block for itself to perform self-perception operations, the interference effect of adjacent network devices may also be considered. For example, the transmit beam configured by the network device may interfere with the receive beam of an adjacent network device, and the transmit beam of an adjacent network device may interfere with the receive beam of the network device. Therefore, the exchange of configuration information between network devices can be used for interference coordination between adjacent network devices. In addition, the transmit beam configured by the network device can perform receive-and-send separated receive-perception measurements with the adjacent network device. Therefore, the exchange of configuration information between network devices can be used for the perception measurement reception of adjacent network devices.
