[0003] With the widespread adoption of wireless network devices, the demand for wireless communications is increasing. Future communication systems will not only possess enhanced communication capabilities but also perception capabilities, integrating communication and perception.

[0111] An embodiment of the present application provides a sensing configuration method. In this method, a first device determines configuration information, which is used to configure a sensing block. The sensing block includes a first resource and a second resource. The first resource is used to transmit a sensing signal, and the second resource is used to monitor the reflected signal of the sensing signal, which is received via a receive beam. The first device sends the configuration information to a second device. The second device receives the configuration information, transmits the sensing signal on the first resource via a transmit beam, and monitors the reflected signal on the second resource via a receive beam. This method can implement configuration for self-sensing scenarios.

[0112] The embodiments of the present application can be applied to communication systems of various radio access technologies (RAT), for example, narrowband Internet of Things (NB-IoT) systems, long term evolution (LTE) communication systems, 5G (or new radio (NR)) communication systems, and transition systems between LTE communication systems and 5G communication systems. The transition system can also be called a 4.5G communication system, and of course it can also be a future communication system, such as the sixth generation (6G) or even the seventh generation (7G) system. The embodiments of the present application can also be applied to non-terrestrial networks (NTN), vehicle to everything (V2X), long term evolution-vehicle (LTE-V), vehicle to vehicle (V2V), machine type communications (MTC), Internet of Things (IoT), long term evolution-machine to machine (LTE-machine to machine, LTE-M), machine to machine (M2M), or future mobile communication systems.

[0113] Please refer to Figure 1, which is a schematic diagram of a perception network scenario. The perception network may include core network equipment, access network equipment (such as the network equipment shown in Figure 1), and terminal equipment (such as vehicles and mobile phones shown in Figure 1). Perception signaling, such as perception demand information, configuration request information, and configuration information, can be transmitted between network equipment and terminal equipment via the Uu interface, between terminal equipment via the sidelink (SL) interface, between core network equipment (such as the sensing management function (SEMF) network element) and network equipment (such as the sensing management function network element and terminal equipment), and between vehicle equipment (such as the vehicle equipment and roadside unit) shown in Figure 1, through the Internet of Vehicles. Optionally, the terminal equipment may also integrate the perception management function. Optionally, the network equipment may be a node responsible for both communication and perception management, such as a dedicated node integrated with the SEMF. The 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 required perception target results. Optionally, the perception measurement results include the geographic location, distance, speed, angle, map, posture, scale, imaging, and material of the perceived target. In other words, the device configured with SEMF has the ability to determine the required perception block, receive the perception measurement results, and calculate the perception results based on the measurement results.

[0114] Please refer to Figure 2, which is a schematic diagram of another scenario of a perception network. The perception network may include access network equipment (such as network equipment) and terminal equipment. The terminal equipment may be a disconnected terminal equipment, a connected terminal equipment, a passive terminal equipment, an idle terminal equipment, an inactive terminal equipment or a low-power terminal equipment. The network equipment or the terminal equipment may be configured with SEMF, and has the ability to determine the required perception block, receive perception measurement results, and calculate the perception results based on the measurement results. In the scenario of the perception network shown in Figure 2, perception signaling such as perception demand information, configuration request information, configuration information, etc., may occur between the network equipment and the terminal equipment, such as through the Uu interface, or may occur between the terminal equipment, such as through the SL interface.

[0115] Please refer to Figure 3, which is a schematic diagram of the structure of a perception device provided in an embodiment of the present application. The perception device can support a dedicated perception node or a dedicated perception mode, wherein, in the dedicated perception node or dedicated perception mode, the perception device (such as a network device or terminal device that performs self-perception operations) can interact with a device having SEMF (such as a core network device, network device, or terminal device) through a Uu interface, SL interface, F1 interface, or 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 configuration information, which is used to configure the perception block. According to the configuration information, the perception device sends a perception signal on the first resource by sending a beam Tx, and listens to the reflected signal of the perception signal on the second resource by receiving a beam Rx (optionally, the reflected 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 perception signal can be an orthogonal frequency division multiplexing (OFDM) symbol, a single carrier or a frequency modulated continuous wave (FMCW) symbol.

[0116] Please refer to Figure 4, which is a schematic diagram of the structure of a perception device provided in an embodiment of the present application. The perception device supports a communication perception fusion node or a communication perception fusion mode. In this mode, a device with a SEMF and the perception device exchange control and data via a Uu interface, a SL interface, an F1 interface, or an NG interface. Optionally, the device with a 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 a SEMF and the perception device can also interact through interfaces between network devices and terminal devices, interfaces between terminal devices and terminal devices, interfaces between core network devices and network devices, interfaces between core network devices and terminal devices, and interfaces between centralized units and distributed units of network devices, such as for control and data exchange. The difference from the perception device shown in Figure 3 is that the control interaction includes both communication control information, such as downlink data scheduling information, and perception control information, such as the configuration information described in the embodiment of the present application. Correspondingly, the data interaction between the device with a SEMF and the perception device also includes both communication data, such as interaction via a physical downlink shared channel, and perception data, such as reporting of perception measurement results. That is, the sensing device can communicate with other nodes and perform sensing measurements. This communication and sensing fusion model of the sensing device shown in Figure 4 can maximize the sharing of communication and sensing hardware and software resources, as well as spectrum resources.

[0117] Optionally, the network device and terminal device in Figure 1 or Figure 2 can be perception devices supporting the communication perception fusion mode shown in Figure 4, and the terminal device in Figure 1 or Figure 2 can be perception devices supporting the dedicated perception mode shown in Figure 3.

[0118] A network device is an access network (AN) device, such as a base station, that allows a terminal to access a mobile communication system wirelessly.

Multiple DUs can be centrally controlled by one CU. CU and DU can be divided according to the protocol layer functions of the wireless network they possess, for example, the functions of the packet data convergence protocol (PDCP) layer and above protocol layers are set in the CU, and the functions of the protocol layers below the PDCP, such as the radio link control (RLC) layer and the medium access control (MAC) layer, are set in the DU. It should be noted that this division of the protocol layer is only an example, and it can also be divided at other protocol layers. The radio frequency device can be remote and not placed in the DU, or it can be integrated in the DU, or partly remote and partly integrated in the DU, and the embodiments of the present application do not impose any restrictions. In addition, in some embodiments, the control plane (CP) and user plane (UP) of the CU can also be separated and divided into different entities for implementation, 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 pass 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 (RAN) side. In addition, the CU can also be divided as a network device on the core network (CN) side, and this application does not impose any restrictions on this.

[0122] Optionally, a terminal, also known as a terminal device (terminal), user equipment (UE), mobile station (MS), mobile terminal (MT), etc., is a device with wireless transceiver functions that can send signals to network devices or receive signals from network devices. Terminal devices may include user equipment (UE), sometimes also called terminal, access station, UE station, remote station, wireless communication equipment, or user device, etc. The terminal device is used to connect people, objects, machines, etc., and can be widely used in various scenarios, such as but not limited to the following scenarios: cellular communication, D2D, V2X, M2M / MTC, IoT, virtual reality (VR), augmented reality (AR), industrial control, self driving, remote medical, smart grid, smart furniture, smart office, smart wear, smart transportation, smart city, drones, robots and other scenarios.

The network equipment and / or terminal equipment can be deployed on land, including indoors or outdoors, handheld or vehicle-mounted; or can be deployed on the water surface; or can be deployed on aircraft, balloons and artificial satellites in the air. This application does not limit the environment / scenario in which the network equipment and terminal equipment are located.

[0124] To facilitate understanding of the embodiments of the present application, some concepts involved in the embodiments of the present application are explained.

[0125] 1. Self-sensing technology

[0126] Self-perception technology refers to the process of a perception device sending a perception signal and receiving a reflection signal of the perception signal to complete a perception task. It can be applied to perception scenarios such as autonomous driving assistance and unmanned aerial vehicle (UAV) tracking. Optionally, in this application, the perception device can be a perception device supporting a dedicated perception mode as shown in FIG3 , or a communication fusion perception device supporting a communication perception fusion mode as shown in FIG4 , or a communication device, etc.

[0127] 2. Perceived Tasks or Perceived Needs

[0128] Perception tasks or requirements can involve network devices or terminal devices perceiving and identifying specific areas, objects, or events, such as environmental perception, target identification, target positioning, and target imaging. For example, for smart transportation and UAVs, network devices or terminal devices can use wireless bands for perception and generate map information. For another example, when a vehicle or drone is driving, network devices or terminal devices can use wireless bands to perceive and identify dangerous events such as the sudden appearance of a person or object. For another example, in autonomous driving assistance for vehicles or drones, network devices or terminal devices can use wireless bands for perception to obtain high-precision dynamic maps to assist in autonomous driving. For another example, for driving violations, such as vehicles occupying emergency lanes or drones leaving their routes, network devices or terminal devices can use wireless bands for perception, identify the violations, and issue real-time alerts or post-event penalties. For another example, for foreign objects (such as people, animals, and falling rocks) intruding on highways or railway tracks, or drones intruding into no-fly zones (such as airports), network devices or terminal devices can use wireless bands for perception to identify the foreign objects and implement real-time emergency response. For example, in home health monitoring scenarios, such as detecting abnormal postures like falls, network devices or terminal devices can use wireless bands to sense, identify abnormal postures, and issue alerts. For health monitoring such as breathing and heartbeat, network devices or terminal devices can use wireless bands to sense, identify abnormal indicators, and issue alerts. For weather monitoring, network devices or terminal devices can use wireless bands to sense, detect, or predict environmental, climate, and weather changes.

[0129] 3. Sensing block (SEB)

[0130] A perception block includes a first resource and a second resource. The first resource is the time domain resource for transmitting the perception signal, consisting of one or more symbols and referred to as a symbol block. The second resource is the time domain resource for monitoring or receiving the reflection of the perception signal, and may also include one or more symbols or a predefined or configured time period, also referred to as a receive window (Rx window). As shown in Figure 5, the first resource in the perception block is the symbol block corresponding to transmission (Tx), and the second resource is the symbol block corresponding to reception (Rx).

[0131] The configuration information is used to configure the perception block and 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 the size of a time receiving window for monitoring the reflected signal and at least one of a symbol index or a time slot index of the receiving time window.

[0132] 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, the guard period (GP) used 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 a CP. As shown in Figure 5, if the perception mode is a half-duplex perception mode, the perception block also includes a GP for transceiver conversion. Optionally, the perception block includes time domain and frequency domain resources of the control channel, as shown in FIG5 , where control represents the resources occupied by the control channel, and some or all parameters in the configuration information may be sent to the perception device or the receiving device via the control channel.

[0133] The sensing block is used to transmit and receive sensing signals in a certain direction and distance, or in a certain direction and range, or in a certain direction, distance, and range. The configuration of the sensing block must also be combined with the sensing request information requesting 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 angular resolution.

[0134] The number of repetitions of the perception block can also be called the repetition factor. The perception device uses the perception block multiple times to send and receive perception signals according to the number of repetitions, which can improve the signal-to-noise ratio and thus improve the estimation accuracy of the requested distance, angle or speed.

[0135] The sensing signal is transmitted via the Tx beam, and its reflected signal is received via the Rx beam. Each sensing block corresponds to a Tx beam and an Rx beam, which can be called a transceiver beam pair, or the Tx beam and Rx beam of the sensing reference signal (SERS). That is, the Tx beam corresponds to the beam used to transmit the sensing signal, and the Rx beam corresponds to the beam used to receive the reflected sensing signal. For sensing devices with integrated transceivers, the Tx beam and Rx beam overlap in time during full-duplex sensing. During half-duplex sensing, the Tx beam and Rx beam are time-division multiplexed (TDM). The Rx beam monitors the reflected sensing signal within the Rx time window.

[0136] 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.

[0137] 4. Sensing block set (SEB set)

[0138] The configuration information is used to configure one or more sensing block sets, each of which includes at least one sensing block. At least one of the following information is different for the sensing blocks in different sensing block sets: indication information of the first resource, indication information of the second resource, the period of the sensing block, the number of symbols contained in the sensing block, the number of symbols of the sensing signal contained in the sensing block, the start time of the sensing block, whether the sensing block includes a synchronized broadcast block, whether the sensing block includes a synchronization signal, the subcarrier spacing of the sensing signal, the duration of the cyclic prefix of the cyclic prefix of the sensing signal symbol, the frequency domain starting position of the sensing signal, the bandwidth of the sensing signal, the frequency domain starting position of the sensing block, the bandwidth of the sensing block, the guard interval used for transceiver switching, or the number of repetitions of the sensing block. That is, the embodiments of the present application support different sensing block sets with different configuration information and transmit / receive beam pairs, and different sensing block sets can determine the configuration information separately. Optionally, at least one sensing block in the sensing block set can be a sensing block on the same frequency band, which can be used for self-sensing or collaborative sensing. As shown in FIG5 , multiple sensing blocks on the same frequency band constitute a sensing block set. The configuration information of the sensing blocks in different sensing block sets is different, and therefore, they are represented by blocks in different formats.

[0139] Different perception block sets may have at least one of the following information that differs: a periodicity 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 periodicity of the perception block set refers to whether the perception block set, including the plurality of perception blocks, is periodically configured.

[0140] Optionally, different perception block sets correspond to different perception request information, and / or different perception blocks within 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 angular resolution. In other words, a perception block set can be used to complete one or more perception tasks within a period of time, such as environmental perception, target identification, target positioning, and target imaging. Multiple perception blocks within a perception set within a perception cycle can cover the transmission and reception of perception signals in multiple directions and at different distances required by the perception task.

[0141] 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.

[0142] 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.

[0143] The transceiver beam pair configuration of each perception block in the perception block set supports fixed Tx beams and polling each Rx beam to obtain the Rx beam corresponding to the Tx beam; or supports fixed Rx beams and polling 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.

[0144] 5. Transmit beam and receive beam corresponding to the perception block

[0145] The transmit and receive beam pair of the sensing block is determined by the sensing 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.

[0146] Optional implementations including but not limited to determining a transmit beam and / or receive beam of a perception block based on a reference beam are described below.

[0147] 5.1 The sensing device determines the transmit beam and receive beam of the sensing block based on the indication information of the reference beam.

[0148] In an optional embodiment, the reference beam includes one or more first reference beams, the first reference beams serving as transmit beams, and the receive beam is determined based on beam reciprocity and the corresponding transmit beam, wherein the indication information indicates the one or more first reference beams.

[0149] 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 an uplink reference signal beam, such as a channel sounding reference signal beam, an uplink demodulation reference signal beam, or a preamble beam. 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 downlink reference signal beam, such as a synchronization signal or synchronization broadcast block beam, a channel state information reference signal beam, a downlink demodulation reference signal beam, or a positioning reference signal beam.

[0150] 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.

[0151] In another optional embodiment, the reference beam includes one or more second reference beams, the second reference beams serving as receive beams, and the transmit beam is determined based on beam reciprocity and the corresponding receive beams, wherein the indication information indicates the one or more second reference beams.

[0152] Optionally, configuration information is sent to the 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 can 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 the 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 can 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.

[0153] 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.

[0154] In another optional embodiment, 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 and 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 receive beam determined based on the reference beam configured by the configuration information. For example, the transmit and 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 the Rx beam corresponding to the Tx beam; or supporting a fixed Rx beam and polling each Tx beam to obtain the Tx beam corresponding to the Rx beam.

[0155] 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.

[0156] Table 1 Transmitting and receiving beam pair pairing order

[0157] 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.

[0158] Optionally, in this implementation, for the non-reciprocal case, the polling method described above may be used to configure corresponding Tx beams and Rx beams for each sensing block.

[0159] 5.2 The sensing device determines the transmit beam of the sensing block based on the indication information of the reference beam and other parameters, and then determines the receive beam based on beam reciprocity and the corresponding transmit beam.

[0160] 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.

[0161] 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 fact that 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. Based on the 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.

[0162] In another optional embodiment, a first reference beam serves as the first transmit beam, or the first transmit beam is determined based on the first reference beam and the transmit angle offset between the first transmit beam and the first reference beam; and the second transmit beam is determined based on at least two of the transmit beam angle range, the number of transmit beams, and the interval between different transmit beams in the transmit beams, and the first transmit beam. The reference beam includes the first reference beam, and the transmit beam includes the first transmit beam and the second transmit beam.

[0163] That is, in one approach, the configuration information includes information indicating a first reference beam, as well as at least two of the angular range, number, and spacing between different transmit beams. Furthermore, the first reference beam is specified as the starting transmit beam. In another approach, the configuration information includes information indicating a first reference beam, as well as an offset between the transmit angle of the starting transmit beam and the first reference beam, and at least two of the angular range, number, and spacing between different transmit beams. In this approach, the starting transmit beam is determined based on the first reference beam and the offset. Furthermore, in both approaches, the sensing device can determine the remaining transmit beams based on at least two of the angular range, number, and spacing between different transmit beams in the configuration information, combined with the starting transmit beam, and then determine the corresponding receive beams based on beam reciprocity and the corresponding transmit beams, thereby obtaining transmit and receive beam pairs for each sensing block. The number of transmit beams can be the number that would be used without considering the number of repetitions of the sensing block or the fixed scanning beam direction.

[0164] Wherein, if the offset is equal to 0, the starting transmit beam is the first reference beam; if the offset is greater than 0, the starting transmit beam is the beam with the transmit angle obtained by adding the offset to or subtracting the offset from the transmit angle of the first reference beam. For example, please refer to Figure 6, which is a schematic diagram of determining the starting transmit beam based on the reference beam. As shown in Figure 6, if the offset of the transmit angle between the starting transmit beam and the first reference beam in the configuration information is offset = 0, then the first reference beam shown in Figure 6 is the starting transmit beam. Based on beam reciprocity and the starting transmit beam, the starting receive beam shown in Figure 6 can be determined; if the offset of the transmit angle between the starting transmit beam and the first reference beam in the configuration information is offset > 0, then the beam obtained by adding the offset to the transmit angle of the first reference beam shown in Figure 6 is the starting transmit beam. Based on beam reciprocity and the starting transmit beam, the starting receive beam shown in Figure 6 can be determined.

[0165] For example, the configuration information includes indication information for the first reference beam, which is index 1 of the uplink reference signal beam, and stipulates that the starting transmit beam is the uplink reference signal beam. The configuration information also includes that the angular range of the transmit beam is 60 degrees and the number is 2. In this way, the sensing device can obtain an angular size of 30 degrees for each transmit beam based on the angular range of 60 degrees and the number of 2. Based on the transmit angle of beam 1 of the uplink reference signal, the sensing device determines that the first transmit beam is beam 1 and the second transmit beam is a beam with an additional 30-degree offset from the transmit angle of beam 1. Furthermore, based on beam reciprocity and the corresponding first and second transmit beams, the respective Rx beams are determined.

[0166] For another example, the configuration information includes indication information for the first reference beam, which is index 1 of the uplink reference signal beam, and that the transmit angle offset between the starting transmit beam and beam 1 is 30 degrees. The configuration information also includes that the transmit beam angle range is 60 degrees and the number is 2. In this way, the sensing device can determine that the angle size of each transmit beam is 30 degrees based on the 60-degree angle range and the 2-number of transmit beams. Based on the transmit angle of beam 1 of the uplink reference signal, the sensing device can determine that the first transmit beam is a beam with an additional 30-degree offset from the transmit angle of beam 1, and the second transmit beam is a beam with an additional 30-degree offset from the transmit angle of the first transmit beam. Furthermore, based on beam reciprocity and the corresponding first and second transmit beams, the respective Rx beams are determined.

[0167] 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.

[0168] In another optional embodiment, the first reference beam serves 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, 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 be referred to the relevant explanation in the above embodiment, which will not be described in detail here. The difference between this embodiment and the above embodiment is that other transmission beams can be determined based on the starting transmission beam and the interval or offset of different transmission beams.

[0169] 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 interval or offset of different transmission beams is 30 degrees, and based on the transmission angle of beam 1 of the uplink reference signal, the first transmission beam is determined to be beam 1, and the second transmission beam is determined to be the beam with a transmission angle of beam 1 increased by 30 degrees. Then, based on the beam reciprocity and the corresponding first transmission beam and second transmission beam, each Rx beam is determined.

[0170] 5.3 The sensing device determines the receiving beam of the sensing 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.

[0171] 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.

[0172] 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 transmission 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. 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.

[0173] In another optional embodiment, 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 receive angle offset between the first and second reference beams; the second receive beam is determined based on the first receive beam, at least two of the receive beam angle range, the number of receive beams, and the interval between different receive beams in the receive beam. The reference beam includes the second reference beam, and the receive beam includes the first and second receive beams.

[0174] That is, in one approach, the configuration information includes information indicating a second reference beam, as well as at least two of the angular range, number, and spacing between different receive beams. Furthermore, the second reference beam is specified as the starting receive beam. In another approach, the configuration information includes information indicating a second reference beam, as well as an offset between the starting receive beam and the second reference beam, and at least two of the angular range, number, and spacing between different receive beams. In this approach, the starting receive beam is determined based on the second reference beam and the offset. Furthermore, in both approaches, the sensing device can determine the remaining receive beams based on at least two of the angular range, number, and spacing between different receive beams in the configuration information, combined with the starting receive beam. The sensing device then determines the corresponding transmit beam based on beam reciprocity and the corresponding receive beam, thereby obtaining the transmit / receive beam pairs for each sensing block. The number of receive beams can be the number that would be used without considering the number of repetitions of the sensing block or the fixed scanning beam direction.

[0175] Wherein, if the offset is equal to 0, the starting receive beam is the first reference beam; if the offset is greater than 0, the starting receive beam is the beam with the receive angle obtained by adding the offset to or subtracting the offset from the receive angle of the second reference beam. For example, please refer to Figure 7, which is a schematic diagram of determining the starting receive beam based on the reference beam. As shown in Figure 7, if the offset of the receive angle between the starting receive beam and the second reference beam in the configuration information is offset = 0, then the second reference beam shown in Figure 7 is the starting receive beam. Based on beam reciprocity and the starting receive beam, the starting transmit beam shown in Figure 7 can be determined; if the offset of the receive angle between the starting receive beam and the second reference beam in the configuration information is offset > 0, then the beam obtained by adding the offset to the receive angle of the second reference beam shown in Figure 7 is the starting receive beam. Based on beam reciprocity and the starting receive beam, the starting transmit beam shown in Figure 7 can be determined.

[0176] For example, the configuration information includes indication information for the second reference beam, which is index 1 of the downlink reference signal beam, and stipulates that the starting receive beam is the downlink reference signal beam. The configuration information also includes an angular range of 60 degrees and a number of 2 receive beams. In this way, the sensing device can obtain an angular size of 30 degrees for each receive beam based on the angular range of 60 degrees and the number of 2. Based on the receive angle of beam 1 of the downlink reference signal, the sensing device determines that the first receive beam is beam 1 and the second receive beam is a beam with an additional 30-degree offset from the receive angle of beam 1. Furthermore, based on beam reciprocity and the corresponding first and second receive beams, each Tx beam is determined.

[0177] For another example, the configuration information includes indication information for the second reference beam, which is index 1 of the downlink reference signal beam, and that the receiving angle offset between the starting receive beam and beam 1 is 30 degrees. The configuration information also includes that the angle range of the receive beams is 60 degrees and the number of receive beams is 2. In this way, the sensing device can obtain an angular size of 30 degrees for each receive beam based on the angular range of 60 degrees and the number of 2. Based on the receiving angle of beam 1 of the downlink reference signal, the sensing device can determine that the angular size of each receive beam is 30 degrees. Furthermore, based on the receiving angle of beam 1 of the downlink reference signal, the sensing device can determine that the first receive beam is a beam with a 30-degree offset added to the transmit angle of beam 1, and the second receive beam is a beam with a 30-degree offset added to the receive angle of the first receive beam. Furthermore, based on beam reciprocity and the corresponding first and second receive beams, the sensing device can determine each Tx beam.

[0178] 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.

[0179] In another optional embodiment, the second reference beam serves 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 be referred to the relevant explanation 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.

[0180] 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.

[0181] 5.4 The sensing device determines the receiving beam and transmitting beam of the sensing block based on the indication information of the reference beam and other parameters.

[0182] The difference between the implementation of this part and the above implementation is that, in the implementation of this part, the transmit and receive beam pairs are not determined by beam reciprocity. In the case of non-reciprocity, beam scanning pairing is required for the determined receive beam and transmit beam. For example, based on 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).

[0183] The following describes optional implementations of determining the receiving beam and transmitting beam of a perception block based on the indication information of the reference beam and other parameters.

[0184] In an optional embodiment, the first transmit beam is determined based on a first reference beam and an offset of receive angles between the first transmit beam and the first reference beam, and the first receive beam is determined based on a second reference beam and an offset of receive angles between the first receive beam and the second reference beam. The reference beams include the first reference beam and the second reference beam, the transmit beams include the first transmit beam, and the receive beams include the first receive beam.

[0185] In another optional embodiment, 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 between 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 between 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.

[0186] That is, in this embodiment, the configuration information includes not only the reference beam indication but also the spacing or offsets between different transmit beams and the spacing or offsets between different receive beams. The starting transmit beam and the starting receive beam are determined based on the reference beam. 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 spacing or offsets between different transmit beams and the spacing or offsets between different receive beams.

[0187] 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 the beam 1-1 of the uplink reference signal, and the starting receiving beam is the 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.

[0188] In another optional embodiment, 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 at least two of the transmit beam's angular range, the number of transmit beams, and the interval between different transmit beams in the transmit beam, and 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 at least two of the receive beam's angular range, the number of receive beams, and the interval between different receive beams in the receive beam, and the first receive beam. The reference beams include the first reference beam and the second reference beam, the transmit beams include the first transmit beam and the second transmit beam, and the receive beams include the first receive beam and the second receive beam.

[0189] That is, in this embodiment, the configuration information includes, in addition to information indicating the uplink reference signal beam and the downlink reference signal beam, at least two of the transmit beam's angular range, the number of transmit beams, and the spacing between different transmit beams within the transmit beam, as well as at least two of the receive beam's angular range, the number of receive beams, and the spacing between different receive beams within the receive beam. The initial transmit beam and the initial receive beam are determined based on the reference beam, while other transmit beams and other receive beams are determined based on the initial transmit beam and the initial receive beam, respectively, in combination with other parameters.

[0190] 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 may 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 transmit 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 may determine the spatial relationship or transmit beam of the transmitting beam of the perception signal based on the reference signal, and then determine the spatial relationship or receive beam of the receiving beam based on the spatial relationship of the transmitting beam or the transmitting beam.

[0191] Optionally, in an embodiment of the present application, the second device determines the receiving beam and / or transmitting beam based on the reference beam, or uses the reference beam as the receiving beam and / or transmitting beam as described in the embodiment of the present application, or determines the transmitting beam and / or receiving beam based on the transmitting angle and / or receiving angle of the reference beam combined with the offset, or determines the transmitting beam and / or receiving beam based on the spatial relationship of the reference beam, or determines the spatial relationship of the transmitting beam and / or receiving beam based on the spatial relationship of the reference beam, or determines the spatial relationship of the transmitting beam and / or receiving beam based on the spatial relationship of the reference beam, or determines the spatial relationship of the transmitting beam and / or receiving beam using the reference beam.

[0192] 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.

[0193] In this 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 characteristics of one signal by another signal, or the spatial filter of one signal by another signal, may refer to: the spatial relationship (or spatial characteristics or spatial filter) of the transmitting signals is determined according to the receiving signals, or the spatial relationship (or spatial characteristics or spatial filter) of the receiving signals is determined according to the transmitting signals, or the spatial relationship (or spatial characteristics or spatial filter) of the transmitting signals is determined according to the spatial relationship (or spatial characteristics or spatial filter) of the receiving signals, or the spatial relationship (or spatial characteristics or spatial filter) of the receiving signals is determined according to the spatial relationship (or spatial characteristics 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.

[0194] Combined with the above description, the relevant process of the perception configuration method is explained.

[0195] Please refer to Figure 8, which is a flowchart of a perception configuration method provided by an embodiment of the present application. The perception configuration method shown in Figure 8 is described using the example of a first device having a SEMF and a second device serving as a perception device. As shown in Figure 8, the perception configuration method includes but is not limited to the following steps:

[0196] S101. The first device determines configuration information;

[0197] As described above, the configuration information is used to configure the perception block, which includes a first resource and a second resource. The first resource is used to transmit a perception signal, which is sent through a transmit beam, and the second resource is used to monitor a reflected signal of the perception signal, which is received through a receive beam.

[0198] In addition, the configuration information must also include indication information of the reference beam, or must also include indication information of the reference beam and other parameters. Other parameters may include at least two of the aforementioned 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 aforementioned 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.

[0199] Optionally, the relevant content 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.

[0200] In an optional implementation, before the first device determines the configuration information, as shown in Figure 8, it may also include: the first device receives second perception request information from the third device, or 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 for perception, or to request at least one of the angle range or distance range for 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 at least one of the angle range or distance range for requesting perception and the angle resolution based on the perception task or perception requirement from the application function network element.

[0201] 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 angular resolution, according to 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 angular resolution, according to 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.

[0202] In another optional implementation, as shown in FIG8 , the first device may also send a sensing capability request message to the second device, where 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 based on 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. Accordingly, the sensing capability information may include information indicating that the second device has duplex capability or half-duplex capability. 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 referred to as full-duplex sensing capability, and the half-duplex capability is referred to as 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. When the second device has half-duplex perception capability, the Tx beam and the Rx beam are in a time division multiplexing relationship. 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) monitoring the reflected perception signal (i.e., the reflected signal of the transmitted perception signal). Therefore, the half-duplex perception capability and 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.

[0203] 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 the 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 mentioned above, the sending angle can be converted into a sending angle in the global coordinate system.

[0204] 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 mentioned 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.

[0205] 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 where beam reciprocity is used to determine the Tx beam or Rx beam, m=n, and the configuration information needs to configure m perception blocks; for the case where non-beam reciprocity is used to determine the Tx beam and Rx beam, the configuration information needs to include the configuration of m*n perception blocks, and the above-mentioned beam polling rule is used to determine the Tx beam and Rx beam corresponding to each perception block.

[0206] S102. The first device sends configuration information to the second device, and correspondingly, the second device receives the configuration information.

[0207] 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.

[0208] Optionally, the time domain resources, frequency domain resources, and beam resources of the sensing blocks included in the sensing block set may also be configured by RRC signaling, MAC CE signaling, DCI, or SCI signaling, which may be cell-level signaling, group-level signaling, or specific terminal-level signaling.

[0209] 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 can be used to selectively activate certain symbol blocks among the 40 symbol blocks of the perception block set as activated perception blocks. Optionally, the activated symbol blocks or perception blocks 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.

[0210] For periodic perception block set configuration, the first device may further configure a start symbol and a period of the perception block set. The period may be 5ms, 10ms, 20ms, 40ms, and the like.

[0211] 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 being associated with the carrier frequency, with different carrier frequencies corresponding to different maximum number of perception blocks and perception block positions in the perception block set.

[0212] S103. The second device sends a perception signal on the first resource by using a transmitting beam, and monitors a reflected signal on the second resource by using a receiving beam.

[0213] Optionally, the second device determines, based on the configuration information, the first resource used by the Tx beam and the second resource used by the Rx beam of each sensing block. The method for determining the Tx beam and Rx beam of each sensing block can be found in the optional implementations described in Sections 5.1 to 5.3 of the Conceptual Explanation and will not be described in detail here. Optionally, in the case where the configuration information is used to configure multiple sensing blocks and the transmit / receive beam pair corresponding to each sensing block, in step S103, the second device may use each sensing block to scan the Tx beam and Rx beam.

[0214] Optionally, after step S103, the second device may send the perception measurement result to the first device. The first device may determine, based on the perception measurement result, perception response information corresponding to the second perception request information, and may then send 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 order based on the index of the received beam, thereby avoiding the overhead of indicating the beam index when reporting the perception measurement result.

[0215] In an optional implementation, in the perception configuration method shown in Figure 8, 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.

[0216] In another optional embodiment, in the perception configuration method shown in FIG8 , 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, which then performs self-perception-related operations based on the configuration information. The core network device may send configuration information to the network device via the NRPPa interface.

[0217] In another optional embodiment, in the perception configuration method shown in Figure 8, 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.

[0218] In the two aforementioned implementations, the core network device has a perception management function, and the perception blocks used by network devices or terminal devices for self-perception can be configured by the core network device. Because the core network device can know the antenna direction of the network device, the core network device can use a finer granularity to indicate the transmit beam and / or receive beam of the perception block configured for the network device, compared to configuring the transmit beam and / or receive beam of the perception block for the terminal device. For example, the horizontal direction angle or vertical direction angle can be configured at a granularity of 1 degree or 0.1 degree.

[0219] It can be seen that in the perception configuration method shown in FIG8 , the first device can configure a perception block for the second device, so that the second device can use the perception block to perform related operations of self-perception.

[0220] Please refer to Figure 9, which is a flowchart of another perception configuration method provided by an embodiment of the present application. The perception configuration method shown in Figure 9 differs from the perception configuration method shown in Figure 8 in that the second device has a SEMF, and the second device can send a configuration request message to the first device, where the configuration request message is used to request the configuration of the perception block. As shown in Figure 9, the perception configuration method may include:

[0221] 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.

[0222] 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.

[0223] The configuration request information also includes 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, 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 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, 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 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, and 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 or offset of different receive beams.

[0224] In an optional embodiment, before step S201, the second device may also receive first perception request information from the first device, where 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 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 sends a configuration request information to the first device to request the configuration of the perception block or each perception block in the perception block set.

[0225] For example, the second device determines at least two of the angular range of the transmit beam, the number of transmit beams, or the interval between different transmit beams requested by the configuration request information 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 used in the first perception request information. For another example, the second device determines at least two of the angular range of the receive beam, the number of receive beams, or the interval between different receive beams requested by the configuration request information 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 used in the first perception request information. For another example, the second device determines at least two of the angular range of the transmit beam, the number of transmit beams, or the interval between different transmit beams requested by the configuration request information, and at least two of the angular range of the receive beam, the number of receive beams, or the interval between different receive beams requested by the configuration request information, 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 used in the first perception request information.

[0226] Optionally, as shown in Figure 9, the first device may receive second perception request information from the third device, and then send 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.

[0227] In one optional embodiment, the second device calculates at least two of the required number, angular range, or spacing of Tx and Rx beams based on the first sensing request information from the first device and its own sensing capability information, such as antenna configuration and supported angular resolution. The second device then sends this configuration request information to the first device.

[0228] In another optional embodiment, 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. In response, the second device receives the sensing capability request message and sends the sensing capability information of the second device to the first device. Then, the first device sends the first sensing request information to the second device based on 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 based on the first sensing request information.

[0229] S202. The first device determines configuration information according to the configuration request information, where the configuration information is used to configure the perception block.

[0230] 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 mentioned above, or further requests configuration of 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 perception signal symbol, 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 and 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 and 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 and receive beam pair in the configuration information according to the configuration request information 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, and the interval or offset of the 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, and the interval or offset of the 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, and the interval or offset of the 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 the reference beam of the starting receive beam requested to be 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 requested to be configured according to the configuration request information, such as the offset of the receiving angle between the starting transmit beam or the starting transmit beam and the reference beam. Consider the offset of the transmitting angles between the beams, such as at least two of the angle range of the transmitting beam requested to be configured, the number of transmitting beams, or the interval between different transmitting beams in the transmitting beam, and the interval or offset between different transmitting beams, as well as the relevant parameters of the above-mentioned receiving beam requested to be configured, such as the reference beam of the starting receiving beam or the offset of the receiving angle between the starting receiving beam and the reference beam, such as at least two of the angle range of the receiving beam requested to be configured, the number of receiving beams, or the interval between different receiving beams in the receiving beam, and the interval or offset between different receiving beams, to determine the relevant parameters of the transmitting and receiving beam pairs in the configuration information.

[0231] In another optional implementation, the first device determines configuration information based on the configuration request information, including: determining configuration information for m*n sensing blocks for beam scanning pairing based on the m Tx beams and n Rx beams requested by the second device in the configuration request information. Optionally, the first device may coordinate potential interfering resources with the beam configuration expected to be used by the second device based on available system resources, and configure Tx and Rx beam pair resources for the second device.

[0232] Optionally, the first device determines configuration information based on the configuration request information, including: determining, by the first device, configuration information for m sensing blocks for beam scanning pairing based on the m Tx beams and beam reciprocity beams requested by the second device in the configuration request information as Rx beams. Optionally, the first device may coordinate potential interference resources with the beam configuration expected to be used by the second device based on available system resources, and perform resource configuration for the Tx and Rx beam pairs on the second device.

[0233] 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.

[0234] It can be seen that in this embodiment, the second device determines the resource requirements, such as the transmit and receive beam pair that meets 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.

[0235] S203. The first device sends configuration information to the second device, and correspondingly, the second device receives the configuration information.

[0236] S204. The second device sends a perception signal on the first resource by using a transmitting beam, and monitors a reflected signal on the second resource by using a receiving beam.

[0237] 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.

[0238] 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.

[0239] In another embodiment, the first device may be a network device. The network device determines configuration information and sends the configuration information to the underlying layer, configuring a perception block for itself, thereby facilitating 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 effects 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 allows adjacent network devices to perform interference coordination. In addition, the transmit beam configured by the network device can perform receive-and-transmit separated reception perception measurements with adjacent network devices. Therefore, the exchange of configuration information between network devices allows the perception measurement reception of adjacent network devices.
