Description

Technical Field

[0001] The embodiments of the present application relate to the field of communications, and in particular to a communication perception method and apparatus. Background Art

[0002] With the widespread adoption of internet applications and wireless network devices, the demand for wireless communications has further increased, and communication technology is constantly evolving. From 4th generation (4G) mobile communications to 5th generation (5G) mobile communications and then to the next generation (such as 6th generation (6G)), the communication spectrum has also evolved from low-frequency bands to high-frequency bands such as millimeter waves, terahertz, and optical communications.

[0003] Future communication systems (such as next-generation communication systems) may not only possess enhanced communication capabilities but also perception capabilities. Such communication systems can be called synaesthesia-integrated systems. Synaesthesia-integrated systems combine communication and perception, enabling the system to possess both communication and perception capabilities. For perception, the transmission, reflection, and scattering of radio waves can be used to perceive and characterize the environment, enabling high-precision positioning and tracking, gesture and activity recognition, simultaneous localization and mapping (SLAM), and human sensory enhancement.

[0004] However, the perception efficiency of the current synaesthesia system is low, so how to improve the perception efficiency is an urgent problem to be solved. Summary of the Invention

[0006] In a first aspect, a communication perception method is provided. The method can be performed by a first node, or by a component of the first node, such as a processor, circuit, chip, or chip system of the first node, or by a logic module or software capable of implementing all or part of the functions of the first node. The method includes: determining first configuration information of a first signal, the first signal being used for perception, the first configuration information indicating a signal type and / or a perception mode, wherein the signal type is a signal type of the first signal, the signal type including one or more of the following: a perception signal, a communication reference signal, or a communication channel, and the perception mode including a self-perception mode and / or a transmit-receive separation perception mode; and sending the first configuration information.

[0007] Based on this solution, the first node can configure the signal type and / or perception mode for perception, for example, configuring the signal type to be at least one of a perception signal, a communication reference signal, and a communication channel, and configuring the perception mode to be a self-perception mode and / or a transmit-receive separation perception mode. Since the configurable signal types include multiple signal types and there are multiple perception modes, the first node can flexibly configure the signal type and perception mode of the first signal. For example, different signal types of first signals and / or perception modes can be configured for perception in different perception scenarios, so that the first signal and the perception mode can be applicable to different perception scenarios, thereby improving perception efficiency.

[0096] In order to facilitate understanding of the technical solutions of the embodiments of the present application, a brief introduction to the relevant technologies of the present application is first given as follows.

[0097] 1. Angle of arrival (AOA) and angle of departure (AOD):

[0098] AOA refers to the angle between the incoming signal direction and the reference direction, while AOD refers to the angle between the transmitted signal direction and the reference direction.

[0099] For example, AOA / AOD can be implemented based on a local coordinate system (LCS) or a global coordinate system (GCS). LCS uses the device itself as the reference system, while GCS uses the Earth as the reference system. GCS is also called a geodetic coordinate system. The X, Y, and Z axes of LCS and GCS represent longitude, latitude, and elevation, respectively.

[0100] Specifically, in the global coordinate system, the azimuth of the signal's arrival angle / departure angle is the angle between the incoming wave direction and the signal's geographic north, and is positive in the counterclockwise direction; the vertical angle of the signal's arrival angle / departure angle is measured relative to the zenith and is positive in the horizontal direction. In the local coordinate system, the azimuth of the signal's arrival angle / departure angle is measured relative to the x-axis of the local coordinate system and is positive in the counterclockwise direction; the vertical angle of the signal's arrival angle / departure angle is measured relative to the z-axis of the local coordinate system and is positive in the XY plane. Taking LCS as an example, Figure 1 As shown, the azimuth and vertical angles of AOA / AOD correspond to and θ.

[0101] 2. Round trip time (RTT):

[0102] RTT refers to the time it takes for a signal to travel from the sender to the receiver and back to the sender. Alternatively, RTT can refer to the time it takes for a signal to travel from the sender to the receiver and back to the sender.

[0103] Exemplarily, the feedback signal may be an acknowledgment (ACK) signal / negative acknowledgment (NACK) signal indicating whether the signal is successfully sent; or, the feedback signal may also be a signal triggered based on the signal.

[0104] Specifically, such as Figure 2 As shown in the figure, the transmitter can send a signal to the receiver at time t1, and the receiver receives the signal from the transmitter at time t2. Based on the triggering of SRS, the receiver sends a feedback signal to the transmitter at time t3, and the transmitter receives the feedback from the receiver at time t4. At this time, RTT = (t4-t1)-(t3-t2).

[0105] 3. User equipment (UE) positioning:

[0106] For example, a UE may send a sounding reference signal (SRS) to multiple radio access network (RAN) nodes (e.g., a base station). After receiving the SRS from the UE, the multiple RAN nodes may respectively send a positioning reference signal (PRS) to the UE. Alternatively, the multiple RAN nodes may respectively send PRS to the UE. After receiving PRS from multiple RANs, the UE may respectively send SRS to the multiple RAN nodes. Thus, a location management function (LMF) deployed in the core network (CN) may determine the RTT corresponding to each of the multiple RAN nodes based on the SRS transmission and reception time and the PRS transmission and reception time. Furthermore, the UE's location may be determined based on the multiple RTTs.

[0107] The new radio positioning protocol (NRPPa) is defined between the LMF and the RAN node, and the long-term evolution (LTE) positioning protocol (LPP) is defined between the LMF and the UE. These protocols support positioning measurement configuration and reporting. In other words, the LMF can support the RAN node and UE in reporting the measured SRS and PRS transmission and reception times based on NRPPa and LPP.

[0108] Specifically, such as Figure 3As shown, the positioning process of the LMF may include: the LMF sends a positioning information request to the UE's serving RAN node, the positioning information request instructing the RAN node to configure SRS resource information for the UE; thus, after receiving the positioning information request, the RAN node determines and informs the UE of the SRS resource information configured for it; then the RAN node may send a positioning information response to the LMF (e.g., the positioning information response may indicate SRS resource information). Then the LMF sends a positioning activation request to the RAN node, the positioning activation request instructing the RAN node to inform the UE to activate SRS transmission; accordingly, after the RAN node informs the UE to activate SRS transmission, it may send a positioning activation response to the LMF. Then the LMF may send measurement requests to multiple RAN nodes respectively, and send auxiliary information and request location information to the UE; wherein the auxiliary information includes PRS resource information, the measurement request instructs multiple RAN nodes to measure SRS, and the request location information instructs the UE to measure PRS. The RAN node sends PRS to the UE. Therefore, after receiving the measurement request, multiple RAN nodes measure the SRS (such as measuring the reception time of the SRS) and report the measured SRS (i.e., sending a measurement response to the LMF); after receiving the requested location information, the UE measures the PRS (such as measuring the reception time of the PRS) and reports the measured PRS (i.e., providing location information to the LMF); the LMF obtains the reception time of the SRS and the reception time of the PRS, and can send a positioning deactivation indication to the RAN to stop positioning.

[0109] After obtaining the SRS reception time and the PRS reception time, the LMF can calculate the RTT corresponding to each RAN node based on the SRS transmission and reception time and the PRS transmission and reception time. Based on the RTT corresponding to each RAN node, the distance between the UE and each RAN node is determined. Then, a circle is drawn with the RAN node as the center and the distance between the UE and the RAN node as the radius to determine the circles corresponding to multiple RAN nodes. The UE is located in the intersection area of ​​the multiple circles.

[0110] 4. Synaesthesia Integration:

[0111] With the widespread adoption of internet applications and wireless network devices, demand for wireless communications has further increased, and communication technology is constantly evolving. From 4th generation (4G) mobile communications to 5th generation (5G) mobile communications and then to next-generation communications (such as 6G), the communication spectrum has also evolved from low-frequency bands to high-frequency bands, such as millimeter waves, terahertz, and optical communications.

[0112] Future communication systems (such as next-generation communication systems) will not only possess enhanced communication capabilities but also perception capabilities. Such communication systems can be called synaesthesia systems. Synaesthesia refers to the integration of communication and perception functions, enabling the communication system to possess both communication and perception capabilities. Specifically, with regard to perception, perception devices (i.e., devices with perception capabilities) can use the transmission, reflection, and scattering of wireless signals to perceive and characterize the environment, thereby performing high-precision positioning and motion path tracking, posture and activity recognition, simultaneous localization and mapping (SLAM), and human sensory enhancement.

[0113] In synaesthesia-integrated systems, default wireless signals are typically used for perception; therefore, the type of wireless signal is not discussed in this system. In other words, regardless of the perception scenario, the wireless signal is used for perception. However, the wireless signal may not be suitable for certain perception scenarios, resulting in reduced perception efficiency in those scenarios. Therefore, improving perception efficiency is an urgent issue to be addressed.

[0114] Since UE positioning can also be considered as achieving UE perception through communication functions, a readily conceivable solution is to directly apply the UE positioning method to the perception function. However, directly applying the above UE positioning to the perception function may have some problems:

[0115] (1) In the UE positioning method, two signals (i.e., SRS and PRS) are required to perceive the target object, which requires a large resource overhead and increases the complexity of the solution.

[0116] (2) In the UE positioning method, the target object needs to have communication capabilities, that is, the target device needs to send SRS and receive PRS; however, for a target object that does not have communication capabilities, it is impossible to perceive the target object, resulting in reduced perception efficiency.

[0117] In view of this, an embodiment of the present application proposes a communication perception method and device, in which the first node can configure the signal type and / or perception mode for perception, for example, configuring the signal type to be at least one of a perception signal, a communication reference signal, and a communication channel, and configuring the perception mode to be a self-perception mode and / or a transmit-receive separation perception mode. Since the configurable signal types include multiple signal types and there are multiple perception modes, the first node can flexibly configure the signal type and perception mode of the first signal, such as configuring first signals of different signal types and / or perception modes for perception in different perception scenarios, so that the first signal and the perception mode can be applicable to different perception scenarios, thereby improving perception efficiency.

[0118] The technical solution provided in this application can be used in various communication systems, which may be cellular systems related to the Third Generation Partnership Project (3GPP), such as fourth-generation (4G) LTE systems, evolved LTE systems (LTE-Advanced, LTE-A) systems, 5G new radio (NR) systems, vehicle-to-everything (V2X) systems, LTE and NR hybrid networking systems, or device-to-device (D2D) systems, machine-to-machine (M2M) communication systems, Internet of Things (IoT), and other next-generation communication systems, such as sixth-generation (6G) communication systems.

[0119] Alternatively, the communication system may also be a non-3GPP communication system, such as an open radio access network (O-RAN or ORAN), a cloud radio access network (CRAN), a wireless fidelity (WiFi) system, or a communication system that integrates multiple of the above communication systems, which is not limited in this application.

[0120] Among them, the above-mentioned communication system applicable to the present application is an example, and the communication system applicable to the present application is not limited to this. It is uniformly described here and will not be repeated below.

[0121] The present application provides an exemplary communication system. The communication system may include at least one first node and at least one second node. Exemplarily, the first node is configured to sense configuration, and the second node is configured to perform sensing.

[0122] Optionally, the first node may be a RAN node. Further, a sensing function (SEF) may be deployed in the RAN node. Alternatively, the first node may be a terminal device or a core network device deployed with the SEF.

[0123] The transmission of the signaling (i.e., the signaling carrying the first configuration information) may occur between multiple RAN nodes (e.g., Xn interface). The first node may be a RAN node and the second node may be another RAN node other than the first node. Specifically, Figure 4As shown, the first node may be a RAN#1 node, or the first node may be deployed on the RAN#1 node; the second node may be a RAN#2 node. Alternatively, the first node may be a RAN#2 node, or the first node may be deployed on the RAN#2 node; the second node may be a RAN#1 node.

[0124] Alternatively, the signaling transmission may occur between the RAN node and the terminal device (such as the Uu interface), specifically, Figure 4 As shown, the first node can be deployed on the terminal device, and the second node can be a RAN#1 or RAN#2 node; or, the first node can be a RAN#1 or RAN#2 node, or the first node can be deployed on a RAN#1 or RAN#2 node; the second node can be a terminal device.

[0125] Alternatively, the signaling transmission may occur between multiple terminal devices (such as measuring a sidelink (SL) interface). Specifically, the first node may be deployed on a terminal device (such as Figure 4 The second node may be a terminal device other than the first node.

[0126] Alternatively, the signaling transmission may occur between the CN and the RAN node. Specifically, the first node may be deployed in the CN, and the second node may be a RAN node. Figure 4 As shown, the first node may be a SEF node, and the second node may be a RAN#1 node or a RAN#2 node.

[0127] For example, when signaling transmission occurs between a CN and a RAN node, the first node may communicate directly with the second node; alternatively, the first node and the second node may communicate through an intermediate node (such as an access and mobility management function (AMF)). Signaling transmission is implemented between the second node and the AMF via the NG-L interface, and signaling transmission is implemented between the AMF and the RAN node (such as RAN node #1 and / or RAN node #2) via the NG-C interface.

[0128] See also Figure 5 , is a framework diagram of a communication system provided in an embodiment of the present application. Figure 5In the example, if the first node is RAN node #1 or the first node is deployed on RAN node #1, the second node may be in a terminal device (such as any one of terminal device #1, terminal device #2, terminal device #5, and terminal device #6). If the first node is deployed on the CN, the second node may be RAN node #1. If the first node is deployed on terminal device #2 or terminal device #5, the second node may be RAN node #1. If the first node is deployed on terminal device #6, the second node may be terminal device #7 or RAN node #1. If the first node is deployed on terminal device #1, the second node may be in any one of RAN node #1, terminal device #3, and terminal device #4.

[0129] Optionally, the communication system may further include a third node, the third node being configured to provide sensing requirements. Exemplarily, the third node may be any one of a terminal device, a RAN node, or a SEF node deployed in the CN.

[0130] Specifically, the sensing requirement may also be a measurement request and / or a configuration request. For example, the third node may be Figure 4 or Figure 5 Any one of the terminal device, RAN node, or SEF node deployed in CN.

[0131] Exemplarily, in the case where the third node is a SEF node deployed in the CN, the third node may be the first node, or the third node may be a node other than the first node.

[0132] When the third node is a terminal device, the third node may be the first node or the second node, or the third node may be a terminal device other than the first node or the second node. Similarly, when the third node is a RAN node, the third node may be the first node or the second node, or the third node may be a RAN node other than the first node or the second node.

[0133] For the convenience of description, the third node is taken as an example to be another device other than the first node and the second node. The third node is described uniformly here and will not be repeated.

[0134] Optionally, the RAN node in the embodiment of the present application is a node that connects a terminal device to a wireless network. The RAN node may be a node (or device) in a wireless access network, which may also be referred to as a base station, or may also be referred to as a RAN device. For example, the RAN node may include an evolved base station (NodeB or eNB or e-NodeB, evolutionary Node B) in an LTE system or an LTE-A system, such as a traditional macro base station eNB and a micro base station eNB in ​​a heterogeneous network scenario. Alternatively, it may include a next generation node B (gNB) of wideband code division multiple access (WCDMA). Alternatively, it may include a transmission reception point (TRP), a home base station (e.g., home evolved NodeB, or home Node B, HNB), a baseband unit (BBU), a baseband pool (BBU pool), a base transceiver station (BTS) in a global system for mobile communication (GSM) or code division multiple access (CDMA) network, or a WiFi access point (AP), etc. Alternatively, it may include a base station in a non-terrestrial network (NTN), that is, it may be deployed on a high-altitude platform or satellite. In the NTN, the RAN node may serve as a layer 1 (L1) relay, or as a base station, or as a distributed unit (DU), or as an integrated access and backhaul (IAB) node. Alternatively, the RAN node may be a device that implements base station functions in the IoT, such as a device that implements base station functions in V2X, D2D, or machine to machine (M2M), or it may include an in-vehicle device or a wearable device, or it may include an access network device in a 5G network or a public land mobile network (PLMN) that evolves after 5G, and the embodiments of the present application are not limited thereto.

[0135] In some possible scenarios, the RAN node in the embodiments of the present application may also be a module or unit that can implement some of the functions of the base station. For example, the access network equipment may be a centralized unit (CU), a distributed unit (DU), a CU-control plane (CP), a CU-user plane (UP), or a radio unit (RU). The CU and DU may be set separately or included in the same node, such as a baseband unit (BBU). The RU may be included in a radio frequency device or radio frequency unit, such as a remote radio unit (RRU), an active antenna unit (AAU), or a remote radio head (RRH).

[0136] In different systems, CU (or CU-CP and CU-UP), DU or RU may also have different names, but those skilled in the art can understand their meanings. For example, in the ORAN system, CU can also be called open (open, O)-CU, DU can also be called O-DU, CU-CP can also be called O-CU-CP, CU-UP can also be called O-CU-UP, and RU can also be called O-RU. For the convenience of description, this application uses CU, CU-CP, CU-UP, DU and RU as examples for description. Any unit of CU (or CU-CP, CU-UP), DU and RU in this application can be implemented by a software module, a hardware module, or a combination of a software module and a hardware module.

The terminal may be mobile or fixed.

[0139] Optionally, communication between RAN nodes and terminal devices, between RAN nodes, or between terminal devices can be carried out through licensed spectrum, or through unlicensed spectrum, or through both licensed spectrum and unlicensed spectrum.

[0140] Optionally, communication between RAN nodes and terminal devices, between RAN nodes, or between terminal devices may be performed using a spectrum below 6 gigahertz (GHz), or may be performed using a spectrum above 6 GHz, or may be performed using both a spectrum below 6 GHz and a spectrum above 6 GHz. The embodiments of the present application do not limit the spectrum resources used for wireless communication.

[0141] The communication perception method provided by the embodiment of the present application will be described below in conjunction with the accompanying drawings. It is understandable that in the embodiment of the present application, the first node or the second node can perform some or all of the steps in the embodiment of the present application, and these steps or operations are only examples. The embodiment of the present application can also perform other operations or variations of various operations. In addition, the various steps can be performed in different orders presented in the embodiment of the present application, and it is possible that not all operations in the embodiment of the present application need to be performed.

[0142] See also Figure 6 , is a flow chart of a communication perception method provided in an embodiment of the present application, the communication perception method may include the following steps S601 to S602:

[0143] S601. A first node determines first configuration information for a first signal. The first signal is used for sensing, and the first configuration information indicates a signal type and / or a sensing mode. The signal type is a signal type of the first signal, and the signal type includes one or more of the following: a sensing signal, a communication reference signal, and a communication channel. The sensing mode includes a self-sensing mode and / or a transmit-receive separated sensing mode.

[0144] Exemplarily, the perception signal is a signal dedicated to perception. Specifically, the perception signal may include a chirp signal.

[0145] Exemplarily, the communication reference signal includes but is not limited to one or more of the following: synchronization signal (SS), channel state information reference signal (CSI-RS), demodulation reference signal (DMRS), phase tracking reference signal (PTRS), sounding reference signal (SRS), preamble, and chirp-based reference signal.

[0146] Exemplarily, the communication channels include, but are not limited to, one or more of the following: physical downlink shared channel (PDSCH), physical downlink control channel (PDCCH), physical broadcast channel (PBCH), physical uplink shared channel (PUSCH), physical downlink control channel (PUCCH), physical random access channel (PRACH), sidelink data channel (SL data channel), sidelink control channel (SL control channel), sidelink broadcast channel (SL broadcast channel), sidelink feedback channel (SL feedback channel), and chirp-based channel.

[0147] It should be understood that the above examples exemplify possible implementations of perception signals, communication reference signals, and communication channels. Perception signals, communication reference signals, and communication channels may also have other possible implementations besides the above examples, and the embodiments of the present application are not limited thereto.

[0148] Optionally, the self-sensing mode means that the sender of the first signal and the receiver of the echo signal of the first signal are the same, for example, device A sends the first signal and receives the echo signal of the first signal; illustratively, the self-sensing mode can also be called a stand-alone platform mode.

[0149] Optionally, the transmit-receive separation sensing mode means that the sender and receiver of the first signal are different, for example, device A sends the first signal and another device B receives the first signal; illustratively, the transmit-receive separation mode can also be called a dual base station mode or a multi-base station mode.

[0150] Optionally, the waveform carrying the first signal includes one or more of the following: a frequency modulated continuous waveform (FMCW), a multi-carrier orthogonal frequency division multiplexing (OFDM) waveform, and a single carrier waveform.

[0151] Exemplary FMCW waveforms include, but are not limited to, sawtooth waves or triangle waves. When the first signal is carried on a multi-carrier OFDM waveform, the first signal may also be referred to as an OFDM signal; when the first signal is carried on a single-carrier waveform, the first signal may also be referred to as a single-carrier signal. For example, the first signal may be a discrete Fourier transform-spreading-OFDM (DFT-s-OFDM) signal.

[0152] S602: The first node sends first configuration information to one or more second nodes. Correspondingly, the one or more second nodes receive the first configuration information from the first node.

[0153] For example, for the convenience of description, a second node is used as an example for description below. The implementation of any second node among one or more second nodes is the same as the implementation of the second node described below. For details, please refer to the relevant description of the second node described below, which will not be repeated here.

[0154] Exemplarily, the second node may be a RAN node or a terminal device. Specifically, if the first node is a RAN node, or if the first node is an SEF node and the SEF node is deployed in the RAN or CN, the second node may be another RAN node or terminal device other than the first node. If the first node is an SEF node and the SEF node is deployed in a terminal device, the second node may be another terminal device other than the first node.

[0155] Optionally, the first configuration information can be carried in any one of downlink control information (DCI), media access control-control element (MAC-CE) signaling, radio resource control (RRC) signaling, SEF to base station signaling such as perception protocol signaling or NRPPa signaling, and SEF to UE signaling such as perception protocol signaling or LPP signaling.

[0156] Exemplarily, when the first node is a RAN node; or when the first node is a SEF node deployed in the RAN and the second node is a terminal device, the first configuration information may be carried in any one of DCI, MAC-CE signaling, and RRC signaling. When the first node is a SEF node deployed in the CN and the second node is a RAN node or a terminal device, the first configuration information may be carried in NRPPa signaling, LPP signaling, MAC-CE signaling, or RRC signaling.

[0157] In the communication perception method proposed in the embodiment of the present application, the first node can configure the signal type and perception mode for perception, for example, configuring the signal type to be at least one of a perception signal, a communication reference signal, and a communication channel, and configuring the perception mode to be a self-perception mode and / or a transmit-receive separation perception mode. Since the configurable signal types include multiple signal types and there are also multiple perception modes, the first node can flexibly configure the signal type and perception mode of the first signal. For example, different signal types of first signals and perception modes can be configured for perception in different perception scenarios, so that the first signal and perception mode can be applicable to different perception scenarios, thereby improving perception efficiency.

[0158] The above is an overall description of the communication perception method provided in the embodiment of the present application. The following is a detailed description of the "first configuration information" involved in the above embodiment.

[0159] Optionally, the first configuration information may include a signal type to directly indicate the signal type of the first signal. Alternatively, the first configuration information may indicate the resource of the first signal and / or a perception measurement report based on the first signal, thereby implicitly indicating the signal type of the first signal. Alternatively, the first configuration information may also indicate the signal type of the first signal in any other possible manner, which is not limited in the embodiments of the present application.

[0160] In a possible implementation, when the first configuration information indicates perception measurement reporting based on the first signal, the first configuration information may indicate one or more of perception measurement reporting based on the perception signal, perception measurement reporting based on the communication reference signal, and perception measurement reporting based on the communication channel.

[0161] Exemplarily, when the first configuration information indicates perception measurement reporting based on a perception signal, the signal type of the first signal includes the perception signal; when the first configuration information indicates perception measurement reporting based on a communication reference signal, the signal type of the first signal includes the communication reference signal; when the first configuration information indicates perception measurement reporting based on a communication channel, the signal type of the first signal includes the communication channel.

[0162] Optionally, the perception measurement reporting based on the first signal includes perception measurement reporting based on the first signal and / or perception measurement reporting of an echo signal of the first signal.

[0163] In another possible implementation, the first configuration information may indicate one or more resource sets used to carry the first signal. That is, the first configuration information may indicate one or more resource sets used to carry the first signal.

[0164] In one implementation, the resource set includes one or more of a resource set for perception signals, a resource set for communication reference signals, and a resource type for communication channels. Specifically, when the resource set includes a resource set for perception signals, the signal type of the first signal includes a perception signal; when the resource set includes a resource set for communication reference signals, the signal type of the first signal includes a communication reference signal; and when the resource set includes a resource set for communication channels, the signal type of the first signal includes a communication channel.

[0165] In another implementation, the first configuration information may further indicate one or more of perception measurement reporting based on a perception signal, perception measurement reporting based on a communication reference signal, and perception measurement reporting based on a communication channel. Wherein, when the first configuration information indicates perception measurement reporting based on a perception signal, the signal type of the first signal includes a perception signal, and accordingly, the resource set is used to carry the perception signal; when the first configuration information indicates perception measurement reporting based on a communication reference signal, the signal type of the first signal includes a communication reference signal, and accordingly, the resource set is used to carry the communication reference signal; when the first configuration information indicates perception measurement reporting based on a communication channel, the signal type of the first signal includes a communication channel, and accordingly, the resource set is used to carry the communication channel.

[0166] Optionally, the perception measurement reporting based on the first signal includes perception measurement reporting based on the first signal and / or perception measurement reporting of an echo signal of the first signal.

[0167] Optionally, the above embodiment is introduced by taking the indication of the perception measurement report based on the perception signal and the indication of one or more resource sets used to carry the first signal as an example. In fact, the indication of the perception measurement report based on the perception signal and the indication of one or more resource sets used to carry the first signal can be carried in different information, which is not limited by the embodiment of the present application.

[0168] In combination with the above two implementations, the resource set used to carry the first signal includes: resources used to carry the first signal and / or resources used to carry the echo signal of the first signal.

[0169] Optionally, different resource sets within one or more resource sets may correspond to different perception tasks. For example, the perception tasks may include gesture recognition, target object motion path tracking, traffic flow detection, intrusion detection, etc. Alternatively, the perception tasks may include other implementations, which are not limited by the embodiments of this application.

[0170] For example, different sensing tasks correspond to different sensing requirements, which may include one or more of the following: quality of service (QoS), sensing accuracy, resolution, geographical range, confidence, and refresh frequency of sensing measurement results.

[0171] Specifically, there may be a corresponding relationship between confidence and perception accuracy. Therefore, the confidence level may be used to indicate perception accuracy, or the perception accuracy may be used to indicate confidence. For example, when the confidence level is 95%, the corresponding perception accuracy may be 0.1 meters. Alternatively, there may be other corresponding relationships between perception accuracy and confidence, which are not limited in the embodiments of the present application.

[0172] For the convenience of description, a resource set, i.e., the resource set indicated by the first configuration information for carrying the first signal, is introduced below as an example. It is uniformly explained here that the implementation of other resource sets in one or more resource sets can refer to the relevant description of the following resource sets and will not be repeated.

[0173] Optionally, the resource set includes one or more resources, and the one or more resources are used to carry the first signal and / or the echo signal of the first signal in different spatial directions. Specifically, the spatial direction includes the beam direction; that is, the one or more resources are used to carry the first signal and / or the echo signal of the first signal in different beam directions.

[0174] Exemplarily, since in the self-sensing mode, the second node is used to send the first signal and receive the echo signal of the first signal, the resource set for the first signal needs to include resources that carry the first signal and resources that carry the echo signal of the first signal; thus, one or more resources are used to carry the first signal and / or the echo signal of the first signal in different spatial directions. In the transmit-receive separation sensing mode, the second node is used to send or receive the first signal. Therefore, the resource set for the first signal needs to include resources that carry the first signal; thus, one or more resources are used to carry the first signal in different spatial directions.

[0175] Exemplarily, one or more resources are used to carry the first signal and / or the echo signal of the first signal in different spatial directions, which can also be understood as: each of the one or more resources corresponds to different spatial direction information. Specifically, the spatial direction information corresponding to any one of the one or more resources includes a direction offset or an angle offset that is the same as a reference direction or relative to a reference direction.

[0176] For example, the reference direction may be predefined or configured; accordingly, the spatial direction information may include a direction offset or an angular offset. Alternatively, the reference direction and the direction offset may be determined based on a signal / channel transmitted prior to the first signal; for example, the reference direction may be the direction of a signal / channel transmitted prior to the first signal, and may additionally indicate a direction offset relative to the reference direction.

[0177] Exemplarily, the signal / channel transmitted before the first signal may include one or more of the following: a sensing reference signal (SERS), a non-zero power (NZP) CSI-RS, a synchronization signal broadcast channel block (SSB) (such as a physical cell identifier (PCI) of an SSB or an index of an SSB), SRS, PRS, PDSCH / PUSCH DMRS, and PDCCH / PUCCH DMRS.

[0178] Optionally, in the self-sensing mode, the resources carrying the first signal may also be referred to as transmit (Tx) resources; the resources carrying the echo signal of the first signal may also be referred to as receive (Rx) resources. Furthermore, Tx resources and Rx resources may overlap, such as in the full-duplex self-sensing mode.

[0179] Exemplarily, there is a corresponding relationship between Tx resources and Rx resources, therefore, Tx resources and Rx resources can be referred to as a resource pair; correspondingly, a resource set consisting of one or more resource pairs can also be referred to as a resource pair set.

[0180] For example, since both Tx resources and Rx resources are resources used for sensing, the resources composed of Tx resources and Rx resources can also be called sensing blocks (SEB), or the resources composed of Tx resources and Rx resources can also have other names, which is not limited in the embodiments of the present application.

[0181] Optionally, in half-duplex mode, a guard period (GP) exists between the Tx resource and the Rx resource. For example, the difference between the end time of the Tx resource and the start time of the Rx resource is greater than or equal to the GP.

[0182] Optionally, each of the one or more resources corresponds to one or more resource parameters.

[0183] As a first example, the first configuration information indicates a resource set, including: the first configuration information includes first dedicated resource parameters corresponding to one or more resources. In other words, the one or more resource parameters corresponding to each resource include the first dedicated parameter corresponding to the resource. Furthermore, the first configuration information may also include an index of the one or more resources. In this example, the one or more resource parameters corresponding to different resources are configured separately.

[0184] Among them, the first dedicated resource parameters include one or more of the following: spatial direction information, sub-carrier spacing (SCS) of the first signal, cyclic prefix (CP) corresponding to the SCS, symbol length of the first signal, sub-carrier bandwidth of the first signal, number of first signal resource blocks containing a predefined or configurable number of first signal sub-carriers, slope of the sub-carriers of the first signal, sending time of the first signal, receiving time of the first signal and / or the echo signal of the first signal, bandwidth of the first signal, frequency band of the first signal, sending power of the first signal, frequency starting point, frequency reference starting point, repetition factor, repetition interval, transmission period; among them, bandwidth, frequency band, frequency starting point, and frequency reference starting point are used to determine the frequency domain resources of the first signal; repetition factor indicates the number of repeated transmissions of the first signal; and repetition interval indicates the time interval between two adjacent repeated transmissions of the first signal.

[0185] Illustratively, the frequency reference starting point A is a common reference point for frequency, which is the center frequency of the first subcarrier 0 of the common resource block RB 0. Each resource using a specific subcarrier spacing starts at a frequency point that is offset relative to point A. Specifically, for the first signal, the frequency point that is offset relative to point A is the frequency starting point of the first signal.

[0186] For example, the repetition factor can affect the perception accuracy, reliability, perception distance, and Doppler resolution of the first signal. The repetition interval can also affect the maximum ambiguity distance, perception accuracy, combined signal-to-noise ratio (SNR) of the first signal, and Doppler resolution.

[0187] Optionally, the size of the SCS can reflect the minimum perception distance in half-duplex mode, and the SCS of the first signal can be the maximum SCS required during the perception process. Furthermore, the size of the SCS can also affect the maximum perception distance of a single symbol. For example, when the first node is not deployed in the CN, the first node can determine the SCS of the first signal based on the SCS value or SCS value range that meets the perception requirements indicated by a third node (such as an SEF node deployed in the CN).

[0188] Optionally, when the waveform carrying the first signal is continuous wave modulation or frequency hopping continuous wave modulation (FMCW), the first dedicated resource parameters may include one or more of the following: the subcarrier spacing of the first signal, the symbol length of the first signal, the subcarrier bandwidth of the first signal, the number of first signal resource blocks containing a predefined or configurable number of first signal subcarriers, the slope of the subcarriers of the first signal, the number of subcarriers of the first signal, the bandwidth of the first signal, and the starting frequency of the subcarrier or frequency resource of the first signal. The subcarrier spacing corresponds to the frequency spacing of different chirp signals, and the slope of the subcarriers of the first signal corresponds to the ratio of the subcarrier bandwidth of the first signal to its corresponding symbol length. FMCW can suppress self-interference during transmission and reception during self-sensing through frequency modulation, thereby reducing latency. The bandwidth of the first signal is positively correlated with the resolution of the perceived distance / duration; a larger bandwidth provides a higher corresponding resolution. Furthermore, configuring different resources with different bandwidths through dedicated resource parameters can support different distance resolutions for different resources or different beam directions. This can meet the requirements of practical systems, such as the different longitudinal and lateral positioning accuracy requirements for vehicle driving or autonomous driving.

[0189] Optionally, the reception time of the first signal and / or the echo signal of the first signal may include a reception time window. The length of time between the start time and the end time of the reception time window is related to the perceived target distance. For example, the target distance is positively correlated with the time length.

[0190] For example, the start and end times of the receive time window are different in different duplex modes. Duplex modes include half-duplex mode and full-duplex mode. For example, in the self-sensing mode, if the duplex mode is half-duplex mode, Tx resources and Rx resources do not overlap; if the duplex mode is full-duplex mode, Tx resources and Rx resources may overlap.

[0191] Optionally, the transmit power of the first signal may be determined based on reference path loss information, that is, the first dedicated parameter includes reference path loss information, wherein the reference path loss information is used to determine the transmit power of the first signal.

[0192] Exemplarily, the reference path loss information includes the expected received power P target , reference path loss PL reference , and the correlation factor alpha of the reference path loss. Among them, PL reference is the path loss of the reference path loss signal transmitted between the first node and the second node.

[0193] Specifically, P target PL reference The following relationship (1) can be satisfied between , alpha, and the transmission power of the first signal:

[0194] Transmission power of the first signal = P target +PL reference *alpha relationship (1)

[0195] Exemplarily, the reference path loss signal may include one or more of the following: SERS, SSB, SRS, PDSCH / PUSCH DMRS, PDCCH / PUCCH DMRS, CSI-RS, preamble, wake-up signal (WUS), and chirp.

[0196] Optionally, the sender and receiver of the first signal may be located in the same serving cell or different serving cells.

[0197] Optionally, the frequency band in which the first signal is located includes frequency range 1 (FR1) and / or frequency range 2 (FR2).

[0198] For example, different frequency bands correspond to different single carrier bandwidths and aggregate bandwidths. For example, for FR1, the single carrier bandwidth may include, but is not limited to, one or more of the following: 5 MHz, 10 MHz, 20 MHz, 40 MHz, 50 MHz, 80 MHz, and 100 MHz. For FR2, the single carrier bandwidth may include, but is not limited to, one or more of the following: 50 MHz, 100 MHz, 200 MHz, and 400 MHz.

[0199] Based on this example, one or more resource parameters corresponding to different resources are configured separately. Therefore, the first node can configure different resource parameter values ​​for each resource, thereby improving the flexibility of the resources. For example, the first node can configure the resource parameter values ​​corresponding to each resource based on the perception requirements; so that the resources can be suitable for different perception requirements.

[0200] As a second example, the first configuration information indicates a resource set, including: the first configuration information includes a first common resource parameter and second dedicated resource parameters corresponding to one or more resources; further, the first configuration information may also include indexes of the one or more resources. In this example, some resource parameters (i.e., the first common resource parameters) of the one or more resource parameters are shared configurations.

[0201] The first public resource parameter includes the frequency reference starting point and / or the transmission period of the first signal resource; the second dedicated resource parameter includes one or more of the following: the SCS of the first signal, the CP corresponding to the SCS, the transmission time of the first signal, the reception time of the first signal and / or the echo signal of the first signal, the bandwidth of the first signal, the frequency band of the first signal, the transmission power of the first signal, the repetition factor, and the repetition interval. The reception time of the first signal and / or the echo signal of the first signal may be a reception time range.

[0202] Exemplarily, shared configuration means that some resource parameters among one or more resource parameters are configured uniformly, so that the values ​​of the parameters corresponding to each resource are the same, that is, each resource can share the uniformly configured parameters.

[0203] Exemplarily, in this example, the resource parameters of each resource in one or more resources are configured based on two levels. For example, the first node can configure the value of the first common resource parameter at the resource set level so that the value of the first common resource parameter corresponding to each resource in the resource set is the same; or the first node can configure the first common resource parameter at the frequency layer level so that the common resource parameters corresponding to resources in the same frequency layer are the same.

[0204] As a third example, the first configuration information indicates a resource set, including: the first configuration information includes second common resource parameters corresponding to one or more resources; further, the first configuration information further indicates indexes of the one or more resources. In this example, all resource parameters (i.e., the second common resource parameters) in the one or more resource parameters are shared configurations.

[0205] Among them, the second public resource parameters include one or more of the following: frequency reference starting point, symbol length of the first signal, subcarrier spacing of the first signal, subcarrier bandwidth of the first signal, slope of the first signal, bandwidth starting frequency of the first signal, and transmission bandwidth of the first signal.

[0206] Exemplarily, in this example, the first node can configure the second common resource parameters at the frequency layer level so that the common resource parameters corresponding to the resources of the same frequency layer are the same. For example, when the first signal is a chirp signal, the second common resource parameters correspond to the common resource parameters of the frequency layer, including the frequency reference starting point, the first signal symbol length, the subcarrier spacing of the first signal, the subcarrier bandwidth of the first signal, the number of resource blocks of the first signal including a predefined or configurable number of subcarriers of the first signal, the slope of the first signal (such as the chirp rate), the bandwidth starting frequency of the first signal, and one or more of the transmission bandwidth of the first signal.

[0207] As a fourth example, the first configuration information indicates a resource set, including: the first configuration information includes third common resource parameters corresponding to one or more resources; further, the first configuration information further indicates indexes of the one or more resources. In this example, all resource parameters (i.e., the third common resource parameters) in the one or more resource parameters are shared configurations.

[0208] Among them, the third common resource parameter includes one or more of the following: the identifier (ID) of the resource set of the first signal, the transmission period of the first signal resource, the reception time or reception time range of the first signal and / or the echo signal of the first signal, the repetition factor of the first signal resource, the repetition interval of the first signal resource, and the number of symbols of the first signal resource.

[0209] Exemplarily, in this example, the first node may configure the third common resource parameter at the resource set level so that the common resource parameters (ie, the third common resource parameters) corresponding to the resources in the same resource set are all the same.

[0210] Exemplarily, the first signal includes but is not limited to a chirp signal.

[0211] In combination with the second to fourth examples above, part or all of the one or more resource parameters corresponding to different resources are shared configurations.

[0212] Exemplarily, in the second to fourth examples above, the first node can configure the values ​​of one or more resource parameters (such as the first common resource parameter or the third common resource parameter) at the resource set level, so that the values ​​of the one or more resource parameters corresponding to each resource in the resource set are the same. Alternatively, the first node can configure the values ​​of one or more resource parameters (such as the first common resource parameter or the second common resource parameter) at the frequency layer level, so that the values ​​of the one or more resource parameters corresponding to the resources of the same frequency layer are the same. That is to say, for one or more resources, the one or more resource parameters are all public resource parameters. This configuration is suitable for the configuration when the perception scenarios facing each resource are the same or the initial configuration or there is no prior information, such as each resource corresponding to a different beam direction, as the acquisition of the initial environmental perception quantity, the advantage is that it is simple to implement and has low signaling overhead.

[0213] As a fifth example, the first configuration information indicates a resource set, including: the first configuration information includes third dedicated resource parameters corresponding to one or more resources; further, the first configuration information further indicates an index of the one or more resources. In this example, all resource parameters (i.e., the third dedicated resource parameters) in the one or more resource parameters are configured separately.

[0214] The third dedicated resource parameter includes one or more of the following: resource ID of the first signal, sending time of the first signal, sending power of the first signal, sending angle of the first signal, and receiving angle of the first signal.

[0215] Exemplarily, in this example, the first node can configure the third dedicated resource parameter at the resource level, that is, each resource can be configured with the value of the third dedicated resource parameter respectively.

[0216] Exemplarily, the first signal includes but is not limited to a chirp signal.

[0217] The above five examples respectively introduce how the first node configures resource parameters for one or more resources. In fact, any two or three of the third to fifth examples can also be used in combination. Among them, when any two of the third to fifth examples are used in combination, it can be considered that the resource parameters in one or more resources are configured based on two levels. When the third to fifth examples are used in combination, it can be considered that the resource parameters in one or more resources are configured based on three levels.

[0218] Exemplarily, when the third example is used in combination with the fifth example, the resource parameters in one or more resources are configured based on the frequency layer level and the resource level; that is, the first node can configure the second common resource parameters at the frequency layer level, so that the values ​​of the second common resource parameters corresponding to the resources of the same frequency layer are the same, and the third dedicated resources corresponding to each resource are configured separately at the resource level.

[0219] When the third example is used in conjunction with the fourth example, resource parameters in one or more resources are configured based on the frequency layer level and the resource set level. That is, the first node can configure the second common resource parameter at the frequency layer level so that the values ​​of the second common resource parameter corresponding to resources in the same frequency layer are all the same; and configure the third common resource parameter at the resource set level so that the values ​​of the third common resource parameter corresponding to resources in the same resource set are all the same.

[0220] When the fourth example is used in combination with the fifth example, the resource parameters in one or more resources are configured based on the resource collection level and the resource level; that is, the first node can configure the third common resource parameter at the resource collection level, so that the values ​​of the third common resource parameters corresponding to the resources in the same resource collection are the same, and the third dedicated resources corresponding to each resource are configured separately at the resource level.

[0221] When the third, fourth, and fifth examples are used in combination, resource parameters in one or more resources are configured based on the frequency layer level, the resource set level, and the resource level. That is, the first node can configure the second common resource parameter at the frequency layer level so that the values ​​of the second common resource parameter corresponding to resources in the same frequency layer are all the same; configure the third common resource parameter at the resource set level so that the values ​​of the third common resource parameter corresponding to resources in the same resource set are all the same; and configure the third dedicated resource corresponding to each resource at the resource level.

[0222] Exemplarily, the second common resource parameter is a basic parameter with low variation or difference requirements in various resources and / or resource sets. Using it as a common parameter can reduce overhead; the third common parameter is considered to be a common parameter configuration within a resource set. Typically, it is aimed at a certain perception task, and each resource in the resource set is aimed at meeting the same requirement. Therefore, setting it as a common parameter can reduce overhead and have a certain degree of flexibility; and the third dedicated resource parameter provides maximum configuration flexibility based on demand, such as each resource targeting a different transmission beam angle and / or receiving angle, thereby supporting beam scanning perception detection in a certain area.

[0223] In one possible implementation, the first configuration information may indicate the perception mode in the following manner: the first configuration information may include the perception mode to directly indicate the perception mode of the first signal. Alternatively, the first configuration information may indicate the resource of the first signal and / or the perception measurement report based on the first signal, thereby implicitly referring to the perception mode corresponding to the parameter. Alternatively, the first configuration information may also indicate the perception mode of the first signal in any other possible manner, which is not limited in the embodiments of the present application.

[0224] In one implementation, when the first configuration information indicates perception measurement reporting based on the first signal, the first configuration information may indicate one or more of perception measurement reporting based on the first signal and / or perception measurement reporting of an echo signal of the first signal.

[0225] Exemplarily, when the first configuration information indicates perception measurement reporting based on the first signal, or when the first configuration information indicates perception measurement reporting of the echo signal of the first signal, the sensing mode includes a self-sensing mode; when the first configuration information indicates perception measurement reporting based on the first signal, the sensing mode includes a transmit-receive separation sensing mode. When the first configuration information indicates perception measurement reporting of the first signal and the echo signal of the first signal, the sensing mode includes a hybrid mode of the transmit-receive separation sensing mode and the self-sensing mode.

[0226] Exemplarily, the implementation of the perception measurement reporting based on the first signal may refer to the relevant description in the above embodiment, which will not be repeated here.

[0227] In another implementation, the first configuration information may indicate a resource set used to carry the first signal.

[0228] In one example, the resource set used to carry the first signal includes resources used to carry the first signal and / or resources used to carry the echo signal of the first signal.

[0229] Exemplarily, the resource set for carrying the first signal includes resources for carrying the first signal, that is, when the resources in the resource set are used to carry the first signal, the perception mode includes a transmit-receive separation perception mode; the resource set for carrying the first signal includes resources for carrying the echo signal of the first signal, that is, when the resources in the resource set are used to carry the echo signal of the first signal, the perception mode includes a self-perception mode; or, the resource set for carrying the first signal includes resources for carrying the first signal and resources for carrying the echo signal of the first signal, that is, when the resources in the resource set are used to carry the first signal and the first signal, the perception mode includes a self-perception mode.

[0230] For example, in the self-sensing mode, the second node is used to send the first signal and receive the echo signal of the first signal. Therefore, the resource set for the first signal includes resources that carry the first signal and resources that carry the echo signal of the first signal. In the transmit-receive separation sensing mode, the second node is used to send or receive the first signal. Therefore, the resource set for the first signal includes resources that carry the first signal. Therefore, the second node can learn about the sensing mode through the function of the resource set.

[0231] For example, the implementation of resource collection can refer to the relevant description of resource collection in the above embodiment, which will not be repeated here.

[0232] In another example, the first configuration information may further indicate a perception measurement report based on the first signal and / or a perception measurement report of an echo signal of the first signal. Wherein, when the first configuration information indicates a perception measurement report based on the first signal, the resources in the resource set are used to carry the first signal, and accordingly, the perception mode includes a self-perception mode or a transmit-receive separation perception mode; or when the first configuration information indicates a perception measurement report based on the first signal and the echo signal of the first signal, the resources in the resource set are used to carry the first signal and the echo signal of the first signal, and accordingly, the perception mode includes a self-perception mode.

[0233] Exemplarily, the implementation of the perception measurement reporting based on the first signal may refer to the relevant description in the above embodiment, which will not be repeated here.

[0234] In a possible implementation, in addition to the signal type, perception mode, and resource set, the first configuration information may also indicate other information, for example, it may indicate one or more of the scheduling type of the resource set, one or more second nodes, and the reporting time threshold of the perception measurement results.

[0235] Optionally, when the first configuration information further indicates a scheduling type of the resource set, the scheduling type is any one of periodic scheduling, semi-permanent scheduling, and non-periodic scheduling.

[0236] Exemplarily, when the scheduling type is periodic scheduling, one or more resource parameters corresponding to each resource may also include a transmission period and / or a relative reference time (such as the time offset of the first time slot of the initial frame) to determine the transmission opportunity; the transmission period is the transmission period described in the above two examples.

[0237] Optionally, when the first configuration information further indicates one or more second nodes, the second nodes can perceive according to the first signal.

[0238] Exemplarily, when the perception mode includes a self-perception mode, the first configuration information also instructs the second node to adopt the self-perception mode for perception; when the perception mode includes a transmit-receive separation perception mode, the first configuration information also instructs the second node to adopt a transmit-receive separation perception mode for perception.

[0239] Exemplarily, the first configuration information may include one or more identifiers of the second node. For example, when the second node is a RAN node, the identifier of the second node may include one or more of the ID of the RAN node, the PCI of the RAN node, the cell global identifier (CGI) of the RAN node, the absolute radio frequency channel number (ARFCN) of the RAN node, and the transmission reception point identifier (TRP ID) of the RAN node.

[0240] In a possible implementation, in step S601, the first node may determine the first configuration information based on the first request information, wherein the first request information is used to request the first configuration information.

[0241] Exemplarily, the first request information may be called a configuration request, or the first request information may also have other names, which are not limited in the embodiments of the present application.

[0242] Optionally, when the first configuration information also indicates a reporting time threshold for the perception measurement result, and when the first time difference is less than or equal to the reporting time threshold, the perception measurement result includes the perception measurement result corresponding to the perception signal and / or the communication reference signal, and the first time difference is the difference between the reception time of the first signal and the reporting time of the perception measurement result; when the first time difference is greater than the reporting time threshold, the perception measurement result includes the perception measurement result corresponding to the communication channel.

[0243] Exemplarily, when the perception mode is the self-perception mode, the reception time of the first signal can be replaced by: the reception time of the echo signal of the first signal; that is, the first time difference is the difference between the reception time of the echo signal of the first signal and the reporting time of the perception measurement result.

[0244] Specifically, under the same bandwidth, the first time differences corresponding to first signals of different signal types are different; that is, the time required from the perception measurement of the first signal (such as the reception time of detecting the first signal (or the echo signal of the first signal)) to reporting the perception measurement result (i.e., the first time difference) is different. Among them, the time required for the signal (such as the perception signal and / or the communication reference signal) is less than the time required for the channel (i.e., the communication channel); further, the time required for the signal is less than or equal to the time required for the control channel in the communication channel, and the time required for the control channel is less than or equal to the time required for the data channel in the communication channel. Therefore, the signal type of the first signal can be distinguished by the size relationship between the reporting time threshold and the first time difference.

[0245] Optionally, the first request information comes from a third node, and the third node is used to provide sensing requirements. Specifically, before step S601, if Figure 7 As shown in (a), the communication perception method may further include step S600A:

[0246] S600A: The third node sends a first request message to the first node. Correspondingly, the first node receives the first request message from the third node.

[0247] Optionally, the first request information is used to request one or more of the following: the signal type of the first signal, the perception mode, the resource set carrying the first signal, the scheduling type of the resource set, and the target perception node (i.e., one or more second nodes).

[0248] For example, the signal type of the first signal, the perception mode, the resource set carrying the first signal, the scheduling type of the resource set, and the implementation of one or more second nodes can refer to the relevant description in the above-mentioned first configuration information and will not be repeated here.

[0249] Optionally, when the first node determines the first configuration information based on the first request information, after step S601, the first node may also respond to the first request information. Figure 7 As shown in (a), after step S601, the communication perception method may further include step S603:

[0250] S603: The first node sends response information to the third node in response to the first request information, and the third node receives the response information from the first node, wherein the response information indicates the first configuration information.

[0251] Exemplarily, step S602 may be performed after step S603, or step S602 may be performed simultaneously with step S603, which is not limited in the embodiment of the present application.

[0252] Optionally, after the second node receives the first configuration information, it may determine the perception measurement result based on the first configuration information. Figure 7 As shown in (b), after step S602, the communication perception method may further include the following step S604:

[0253] S604: The second node determines a perception measurement result, where the perception measurement result is a value corresponding to the perception measurement quantity.

[0254] Specifically, the second node may determine the perception measurement result based on the first configuration information. The detailed implementation of step S604 will be described in subsequent embodiments and will not be repeated here.

[0255] Optionally, the perception measurement amount includes a perception measurement reporting amount. Exemplarily, the perception measurement reporting amount may include some or all parameters of the perception measurement amount (i.e., the perception measurement reporting amount includes one or more parameters in the perception measurement amount). In the case where the perception measurement reporting amount includes all parameters of the perception measurement amount, the perception measurement amount may also be referred to as the perception measurement reporting amount.

[0256] Exemplarily, the perception measurement amount may also be a measurement amount corresponding to a certain perception method; therefore, the perception measurement amount included in the perception reporting amount is the measurement amount corresponding to the perception method.

[0257] Optionally, the measurement results reported by the nodes participating in the perception include some or all parameters in the perception measurement results (that is, the measurement results reported by the nodes participating in the perception include one or more parameters in the perception measurement results). In the case where the measurement results reported by the nodes participating in the perception include all parameters in the perception measurement results, the measurement results reported by the nodes participating in the perception may also be referred to as perception measurement results.

[0258] Exemplarily, the perception measurement quantity may also be a measurement quantity corresponding to a certain perception method; accordingly, the perception measurement result is the value of the measurement quantity corresponding to the perception method; thus, the measurement result reported by the node participating in the perception may include the value of the measurement quantity corresponding to the perception method.

[0259] For ease of description, the following takes the case where the perception measurement reporting amount includes all parameters of the perception measurement amount, and accordingly, the measurement result reported by the node participating in the perception includes all parameters in the perception measurement result as an example; that is, the perception measurement reporting amount is the perception measurement amount, and the measurement result reported by the node participating in the perception is the perception measurement result as an example for description. For the case where the perception measurement reporting amount includes some parameters of the perception measurement amount, and / or the measurement result reported by the node participating in the perception includes some parameters in the perception measurement result (such as the case where the perception reporting amount includes the measurement amount of a certain perception method, and / or the measurement result reported by the node participating in the perception includes the value of the measurement amount corresponding to a certain perception method), the implementation is similar to the implementation of the perception measurement amount and the perception measurement result reported by the node participating in the perception described in the following embodiments. For details, reference can be made to the relevant description of the perception measurement amount and the perception measurement result in the following embodiments, and no further details are given.

[0260] Optionally, the perception measurement quantity may be predefined by a protocol, or pre-agreed upon by nodes participating in perception (such as the first node, the second node, the third node, etc.); or indicated by the first node or the third node.

[0261] In a first possible implementation, when the protocol predefines or the nodes participating in the perception pre-agree on the perception measurement quantity, the protocol may also predefine or the nodes participating in the perception may also pre-agree on one or more of the following perception configuration parameters for perception measurement and reporting: perception method, perception measurement time, expected value or measurement value range of the perception measurement quantity, maximum number of transmission paths, number of reports of the perception measurement result, reporting interval of the perception measurement result, number of measurements of the perception measurement result, measurement accuracy of the perception measurement result, and number of samples of the perception measurement result.

[0262] The sensing method includes one or more of the following: RTT sensing, round trip angle (RTA) sensing, and round trip frequency shift (RTF) sensing.

[0263] Exemplarily, RTA sensing refers to sensing the round-trip angle of a measurement signal (e.g., a first signal); alternatively, it may refer to sensing the transmit / receive angle of the measurement signal. Specifically, the round-trip angle (or transmit / receive angle) of the signal may include one or more of the signal's transmit angle, the signal's receive angle, and the difference between the transmit / receive angles. In self-sensing mode, the signal's receive angle may also be replaced by the signal's echo signal's receive angle.

[0264] Similarly, RTF sensing refers to sensing the round-trip frequency of a measurement signal (e.g., the first signal); alternatively, it may refer to sensing the transmit / receive frequency of the measurement signal. Specifically, the round-trip frequency (or transmit / receive frequency) of a signal may include one or more of the signal's transmit frequency, the signal's receive frequency, and the difference between the transmit / receive frequency and the signal's receive frequency. In self-sensing mode, the signal's receive frequency may also be replaced by the signal's echo signal's receive frequency.

[0265] The following is an introduction to each of the above parameters.

[0266] Optionally, different perception methods correspond to different perception measurement quantities. When the perception method includes RTT perception, the perception measurement quantity includes one or more of the following: the sending time of the first signal, the receiving time of the first signal, the receiving time of the echo signal of the first signal, and the sending and receiving time difference of the first signal; when the perception method includes RTA perception, the perception measurement quantity includes one or more of the following: the sending angle of the first signal, the receiving angle of the first signal, the receiving angle of the echo signal of the first signal, and the sending and receiving angle difference of the first signal; when the perception method includes RTF perception, the perception measurement quantity includes one or more of the following: the sending frequency of the first signal, the receiving frequency of the first signal, the receiving frequency of the echo signal of the first signal, and the sending and receiving frequency difference of the first signal.

[0267] For example, based on different sensing modes, the sensing measurement amount can be implemented based on the following two situations:

[0268] Case 1: The perception mode includes the self-perception mode.

[0269] Optionally, in the following case, if the perception method includes RTT perception, the perception measurement quantity includes one or more of the following: the sending time of the first signal, the receiving time of the echo signal of the first signal, and the sending and receiving time difference of the first signal; if the perception method includes RTA perception, the perception measurement quantity includes one or more of the following: the sending angle of the first signal, the receiving angle of the echo signal of the first signal, and the sending and receiving angle difference of the first signal; if the perception method includes RTF perception, the perception measurement quantity includes one or more of the following: the sending frequency of the first signal, the receiving frequency of the echo signal of the first signal, and the sending and receiving frequency difference of the first signal.

[0270] Exemplarily, when the sensing method includes RTT sensing, the time difference between sending and receiving the first signal is the time difference between the sending time of the first signal and the receiving time of the echo signal of the first signal. In this case, the time difference between sending and receiving the first signal can also be called RTT. Specifically, Figure 8 As shown, taking the sending time of the first signal as t1 and the receiving time of the echo signal of the first signal as t2 as an example, the RTT is the difference t2-t1 between t2 and t1.

[0271] Similarly, when the sensing method includes RTA sensing, the transmit / receive angle difference of the first signal is the angle difference between the transmit angle of the first signal and the receive angle of the echo signal of the first signal. When the sensing method includes RTF sensing, the transmit / receive frequency difference of the first signal is the frequency difference between the transmit frequency of the first signal and the receive frequency of the echo signal of the first signal.

[0272] In one implementation, the reception time of the echo signal of the first signal includes the reception time of the first transmission path of the detected echo signal of the first signal.

[0273] Optionally, the time difference between sending and receiving the first signal is the time difference between the first time unit and the second time unit; wherein, the first time unit is the time unit of the first transmission path of the echo signal corresponding to the detected first signal; the second time unit is the time unit with the shortest time between the sending time unit carrying the first signal and the first time unit, and the second time unit is located before the first time unit.

[0274] For example, when there are multiple time units carrying the first signal and multiple time units carrying the echo signal of the first signal, the first time unit carries the first path (i.e., the first transmission path) of the echo signal of the first signal; the second time unit carrying the first signal is the time unit closest to the first time unit among the sending time units carrying the first signal that are located before the first time unit.

[0275] Similarly, the receiving angle of the echo signal of the first signal includes the receiving angle of the first transmission path of the detected echo signal of the first signal, and the receiving and transmitting angle difference of the first signal is the angle difference between the sending angle of the first signal and the receiving angle of the first transmission path (i.e., the first transmission path of the echo signal of the first signal).

[0276] The receiving frequency of the echo signal of the first signal includes the receiving frequency of the first transmission path of the detected echo signal of the first signal, and the receiving and transmitting frequency difference of the first signal is the frequency shift between the sending frequency of the first signal and the receiving frequency of the first transmission path (i.e., the first transmission path of the echo signal of the first signal).

[0277] Illustratively, the time unit may be a minislot, a time slot, a subframe, a symbol, a transmission time interval (TTI), etc.

[0278] In another implementation, the reception time of the echo signal of the first signal includes the reception time of multiple transmission paths of the detected echo signal of the first signal.

[0279] Optionally, the time difference between sending and receiving the first signal includes the time difference between the sending time of the first signal and the receiving time of the echo signal of the first signal on multiple transmission paths.

[0280] Exemplarily, each time the second node sends the first signal, it can correspondingly receive the echo signals of the first signal on multiple transmission paths; thus, the time difference between sending and receiving the first signal may include: the time difference between the sending time unit carrying the first signal and the time unit carrying the echo signal of the first signal on each transmission path.

[0281] Similarly, when the receiving angle of the echo signal of the first signal includes the receiving angles of multiple transmission paths of the detected echo signal of the first signal, the receiving and transmitting angle difference of the first signal includes the angle difference between the sending angle of the first signal and the receiving angles of multiple transmission paths (i.e., multiple transmission paths of the echo signal of the first signal).

[0282] In the case where the receiving frequency of the echo signal of the first signal includes the receiving frequencies of multiple transmission paths of the detected echo signal of the first signal, the receiving and transmitting frequency difference of the first signal includes the frequency shifts between the sending frequency of the first signal and the receiving frequencies of multiple transmission paths (i.e., multiple transmission paths of the echo signal of the first signal).

[0283] Optionally, the time difference between the transmission time of the first signal and the reception time of the echo signal of the first signal on multiple transmission paths can be determined based on the time difference between the reception time of other transmission paths other than the first transmission path among the multiple transmission paths and the reception time of the first transmission path, and / or the time difference between the transmission time of the first signal and the reception time of the first transmission path. Therefore, the perception measurement quantity may also include: the time difference between the reception time of other transmission paths other than the first transmission path among the multiple transmission paths and the reception time of the first transmission path, and / or the time difference between the transmission time of the first signal and the reception time of the first transmission path.

[0284] Similarly, when the reception angle of the echo signal of the first signal includes reception angles of multiple transmission paths of the detected echo signal of the first signal, the perception measurement quantity may further include: angle differences between the reception angles of the other transmission paths and the reception angle of the first transmission path, and / or angle differences between the transmission angle of the first signal and the reception angle of the first transmission path;

[0285] In the case where the receiving frequency of the echo signal of the first signal includes the receiving frequencies of multiple transmission paths of the detected echo signal of the first signal, the perception measurement quantity may also include: the frequency differences between the receiving frequencies of other transmission paths and the receiving frequency of the first transmission path, and / or the frequency difference between the sending frequency of the first signal and the receiving frequency of the first transmission path.

[0286] Case 2: The sensing mode includes a transmitting and receiving separated sensing mode.

[0287] Optionally, in case 2, if the perception method includes RTT perception, the perception measurement quantity includes one or more of the following: the sending time of the second signal, the receiving time of the first signal, the first transmission and reception time difference between the first signal and the second signal (i.e., the time difference between the reception time of the first signal and the sending time of the second signal); if the perception method includes RTA perception, the perception measurement quantity includes one or more of the following: the sending angle of the second signal, the receiving angle of the first signal, the first transmission and reception angle difference between the first signal and the second signal (i.e., the angle difference between the receiving angle of the first signal and the sending angle of the second signal); if the perception method includes RTF perception, the perception measurement quantity includes one or more of the following: the sending frequency of the second signal, the receiving frequency of the first signal, the first transmission and reception frequency difference between the first signal and the second signal (i.e., the frequency difference between the receiving frequency of the first signal and the transmitting frequency of the second signal).

[0288] In one implementation, the reception time of the first signal includes the reception time of the first transmission path of the detected first signal.

[0289] Optionally, the first sending and receiving time difference is a time difference between a sending time of the second signal and a receiving time of the first transmission path of the first signal.

[0290] Similarly, the receiving angle of the first signal includes the receiving angle of the first transmission path of the detected first signal, and the first receiving and transmitting angle difference is the angle difference between the sending angle of the second signal and the receiving angle of the first transmission path (i.e., the first transmission path of the first signal).

[0291] The receiving frequency of the first signal includes the receiving frequency of the first transmission path of the detected first signal, and the first signal receiving and transmitting frequency difference is the frequency shift between the sending frequency of the second signal and the receiving frequency of the first transmission path (i.e., the first transmission path of the first signal).

[0292] In another implementation, the reception time of the first signal includes reception times of multiple detected transmission paths of the first signal.

[0293] Optionally, the first signal receiving and sending time difference includes the time difference between the sending time of the second signal and the receiving time of the first signal on multiple transmission paths.

[0294] Similarly, when the receiving angle of the first signal includes the receiving angles of multiple transmission paths of the detected first signal, the receiving and transmitting angle difference of the first signal includes the angle difference between the sending angle of the first signal and the receiving angles of multiple transmission paths (i.e., multiple transmission paths of the first signal).

[0295] When the receiving frequency of the first signal includes the receiving frequencies of multiple transmission paths of the detected first signal, the first signal receiving and transmitting frequency difference includes the frequency shifts between the sending frequency of the second signal and the receiving frequencies of multiple transmission paths (i.e., multiple transmission paths of the first signal).

[0296] Optionally, the time difference between the transmission time of the second signal and the reception time of the first signal on multiple transmission paths can be determined based on the time difference between the reception time of other transmission paths other than the first transmission path among the multiple transmission paths and the reception time of the first transmission path, and / or the time difference between the transmission time of the second signal and the reception time of the first transmission path. Therefore, the perception measurement quantity may also include: the time difference between the reception time of other transmission paths other than the first transmission path among the multiple transmission paths and the reception time of the first transmission path, and / or the time difference between the transmission time of the second signal and the reception time of the first transmission path.

[0297] Similarly, when the reception angle of the first signal includes the reception angles of multiple detected transmission paths of the first signal, the perception measurement quantity may further include: angle differences between the reception angles of the other transmission paths and the reception angle of the first transmission path, and / or angle differences between the transmission angle of the second signal and the reception angle of the first transmission path;

[0298] In the case where the receiving frequency of the first signal includes the receiving frequencies of multiple detected transmission paths of the first signal, the perception measurement amount may also include: the frequency differences between the receiving frequencies of other transmission paths and the receiving frequency of the first transmission path, and / or the frequency difference between the sending frequency of the second signal and the receiving frequency of the first transmission path.

[0299] Optionally, in case 2, when the sensing method includes RTT sensing, the sensing measurement quantity may further include one or more of the following: the transmission time of the first signal, the reception time of the second signal, and the second transmission / reception time difference between the first signal and the second signal (i.e., the time difference between the reception time of the second signal and the transmission time of the first signal) of another node performing the sensing measurement other than the first node (for convenience of description, this node is referred to as the other node below). Exemplarily, the sum of the first transmission / reception time difference and the second transmission / reception time difference is referred to as the RTT.

[0300] Similarly, when the sensing method includes RTA sensing, the sensing measurement quantity may also include one or more of the following: the transmission angle of the first signal of the other node, the reception angle of the second signal, and the second transmission / reception angle difference between the first signal and the second signal (i.e., the angular difference between the reception angle of the second signal and the transmission angle of the first signal). Exemplarily, RTA may include the difference between the transmission angle of the first signal and the reception angle of the first signal; and / or the difference between the transmission angle of the second signal and the reception angle of the second signal.

[0301] Similarly, when the sensing method includes RTF sensing, the sensing measurement quantity may also include one or more of the following: the transmission frequency of the first signal of the other node, the reception frequency of the second signal, and the second transmission and reception frequency difference between the first signal and the second signal (i.e., the frequency difference between the reception frequency of the second signal and the transmission frequency of the first signal). Exemplarily, the RTF may include the difference between the transmission frequency of the first signal and the reception frequency of the first signal; and / or the difference between the transmission frequency of the second signal and the reception frequency of the second signal.

[0302] For example, the implementation of the receiving time of the second signal, the receiving angle of the second signal, the receiving frequency of the second signal, the second transmit-receive time difference, the second transmit-receive angle difference, and the second transmit-receive frequency difference can refer to the relevant descriptions of the receiving time of the first signal, the receiving angle of the first signal, the receiving frequency of the first signal, the first transmit-receive time difference, the first transmit-receive angle difference, and the first transmit-receive frequency difference in the above embodiments, and will not be repeated here.

[0303] Optionally, in case 2, before step S604, the first node may also determine configuration information of the second signal and send the configuration information of the second signal to the second node. Correspondingly, the second node receives the configuration information of the second signal from the first node.

[0304] Exemplarily, the step of the first node determining the configuration information of the second signal may be performed before step S601, or may be performed after step S601, or may be performed simultaneously with step S601. Correspondingly, the step of the first node sending the configuration information of the second signal to the second node may be performed before step S602, or may be performed after step S602, or may be performed simultaneously with step S602, and this embodiment of the application is not limited thereto.

[0305] Exemplarily, the configuration information of the second signal includes a resource set for carrying the second signal. Specifically, the implementation of the resource set for carrying the second signal is similar to the implementation of the resource set in the above embodiment. For details, please refer to the relevant description of the above resource set, which will not be repeated here.

[0306] Optionally, the perception measurement time includes a reception time of the first signal / an echo signal of the first signal.

[0307] Optionally, the expected value may include one or more numerical values, or the expected value includes a range of values. For example, when the perception method includes RTT perception, the expected value may include one or more of the expected value of the transmit and receive time difference, the expected value of the transmit time, and the expected value of the receive time. When the perception method includes RTA perception, the expected value may include one or more of the expected value of the transmit and receive angle difference, the expected value of the transmit angle, and the expected value of the receive angle; when the perception method includes RTF perception, the expected value may include one or more of the expected value of the transmit and receive frequency difference, the expected value of the transmit frequency, and the expected value of the receive frequency.

[0308] For example, when the transmit and receive beams are reciprocal, the expected values ​​of the transmit angle and the receive angle are the same. In this case, the expected value of the transmit angle or receive angle includes, but is not limited to, one or more of the following: the expected value of the horizontal angle, the uncertainty range of the horizontal angle, the expected value of the vertical angle, and the uncertainty range of the vertical angle. When the transmit and receive beams are not reciprocal, the expected values ​​of the transmit angle and the receive angle differ; therefore, the expected values ​​of the transmit angle and the receive angle can be configured separately. For example, the expected value of the transmit angle includes, but is not limited to, one or more of the following: the expected value of the horizontal transmit angle, the uncertainty range of the horizontal transmit angle, the expected value of the vertical transmit angle, and the uncertainty range of the vertical transmit angle; the expected value of the receive angle includes, but is not limited to, one or more of the following: the expected value of the horizontal receive angle, the uncertainty range of the horizontal receive angle, the expected value of the vertical receive angle, and the uncertainty range of the vertical receive angle.

[0309] Optionally, the second node may determine the perception measurement result based on the maximum number of transmission paths.

[0310] Exemplarily, taking the maximum number as X, where X is a positive integer; the X transmission paths may be the first X transmission paths among the multiple transmission paths corresponding to the detected first signal / the echo signal of the first signal, that is, the first X transmission paths closest to the transmission time of the first signal. Alternatively, the X transmission paths may be the X transmission paths with the strongest signal quality among the multiple transmission paths corresponding to the detected first signal / the echo signal of the first signal. The signal quality can be measured by reference signal received power (RSRP). Taking the self-sensing mode as an example, the transmission and reception time difference of the first signal may include the time difference between the transmission time unit of the first signal and the time unit of the corresponding detected echo signal of the first signal on the X transmission paths; similarly, the transmission and reception angle difference of the first signal may include the angular difference between the transmission angle of the first signal and the reception angle of the corresponding detected echo signal of the first signal on the X transmission paths; and the transmission and reception frequency difference of the first signal may include the frequency difference between the transmission frequency of the first signal and the reception frequency of the corresponding detected echo signal of the first signal on the X transmission paths.

[0311] For example, the value of the number of times the perception measurement result is reported includes but is not limited to any one of 0, 1, 2, 4, 8, 16, 32, and 64; the value of the reporting interval of the perception measurement result includes but is not limited to any one of 1 second, 2 seconds, 4 seconds, 8 seconds, and 16 seconds.

[0312] Optionally, the number of measurements of the perception measurement result is the number of measurements of the same perception measurement quantity, for example, the number of measurements of the transmit / receive time difference, the number of measurements of the transmit / receive angle difference, or the number of measurements of the transmit / receive frequency difference.

[0313] For example, the measurement accuracy of the perception measurement result corresponding to RTT perception may be time accuracy, for example, the time accuracy may be time units. The measurement accuracy of the perception measurement result corresponding to RTA perception may be angle accuracy, for example, the angle accuracy may be degrees. The measurement accuracy of the perception measurement result corresponding to RTF perception may be frequency accuracy, for example, the frequency accuracy may be Hz.

[0314] Exemplarily, the number of samples of the perception measurement result refers to the number of resources where the first signal or the echo signal of the first signal required to be measured to determine the value of a single parameter in the perception measurement result is located.

[0315] Based on this possible implementation, parameters or reports related to perception measurement, such as perception measurement quantities, can be predefined (such as protocol predefined or pre-agreed between nodes), so that the second node can directly perform perception measurement based on these parameters, saving the signaling overhead of indicating these parameters through signaling, while improving perception performance.

[0316] In a second possible implementation manner, when the perception measurement amount is indicated by the first node to the second node, the second node may indicate the perception measurement amount through the second configuration information of the first signal, that is, the second configuration information indicates the perception measurement amount.

[0317] Optionally, the second node determines the perception measurement result based on the first configuration information, including: the second node determines the perception measurement result based on the first configuration information and the second configuration information.

[0318] Optionally, the second configuration information may also indicate one or more of the following: perception method, perception measurement time, expected value or measurement value range of perception measurement quantity, maximum number of transmission paths, number of reports of perception measurement results, reporting interval of perception measurement results, number of measurements of perception measurement results, measurement accuracy of perception measurement results, and number of samples of perception measurement results.

[0319] For example, the implementation of the above parameters can refer to the relevant description of the parameters in the above example, which will not be repeated here.

[0320] In a possible implementation, the second node autonomously determines the second configuration information. In this scenario, illustratively, before step S604, Figure 7 As shown in (b), the first node may further perform the following steps S605 to S606:

[0321] S605: The first node determines second configuration information of the first signal, wherein the second configuration information indicates a perception measurement value.

[0322] Exemplarily, step S605 may be performed before step S601, or step S605 may be performed after step S601, or step S605 may be performed simultaneously with step S601, which is not limited in the embodiment of the present application.

[0323] S606: The first node sends second configuration information to the second node; correspondingly, the second node receives the second configuration information from the first node.

[0324] Exemplarily, step S606 may be performed before step S602, or step S606 may be performed after step S602, or step S606 may be performed simultaneously with step S602, which is not limited in the embodiment of the present application.

[0325] Exemplarily, step S606 may be performed simultaneously with step S602, including: the first configuration information and the second configuration information are carried in the same signaling.

[0326] Optionally, after receiving the second configuration information, the second node may measure the perception measurement amount and obtain a perception measurement result; that is, the perception measurement result is a value corresponding to the perception measurement amount.

[0327] In another possible implementation, the second node determines the second configuration information based on second request information from the third node, wherein the second request information is used to request the perception measurement result.

[0328] Illustratively, the second request information may be called a measurement request, or the second request information may also have other names, which are not limited in the embodiments of the present application.

[0329] For example, Figure 9 As shown, before step S605, the communication perception method further includes step S600B:

[0330] S600B: The third node sends a second request message to the first node; correspondingly, the first node receives the second request message from the third node.

[0331] Exemplarily, step S600B may be performed before step S600A, or after step S600A, or concurrently with step S600A, which is not limited in this embodiment of the present application. It is sufficient to ensure that steps S600B and S605-S606 are performed before step S604. Exemplarily, when step S600B is performed concurrently with step S600A, the first request information and the second request information may be carried in the same signaling.

[0332] Optionally, the first node determines the second configuration information of the first signal, including: the first node determines the second configuration information based on the second request information.

[0333] Optionally, because different second nodes may have different hardware configurations, resulting in different delays in sending and receiving the first signal, different second nodes may have different perceived delays. Therefore, the second request information may also request the timing error of the second node. This allows the third node to obtain the second node's delay, further improving perception accuracy.

[0334] Exemplarily, the implementation of the timing error of the second node can refer to the following related descriptions, which will not be repeated here.

[0335] Optional, such as Figure 9 As shown, before step 604, the communication perception method further includes the following step S607. Correspondingly, after step 604, the communication perception method further includes the following step S608 or steps S608 to S609:

[0336] S607: The first node sends second request information to the second node. Correspondingly, the second node receives the second request information from the first node.

[0337] Exemplarily, step S607 may be performed before step S606, or step S607 may be performed after step S606, or step S607 may be performed simultaneously with step S606, which is not limited in the embodiment of the present application.

[0338] Exemplarily, step S607 may be performed simultaneously with step S606, including: the second configuration information and the second request information are carried in the same signaling.

[0339] S608: The second node sends the perception measurement result to the third node; correspondingly, the third node receives the perception measurement result from the second node.

[0340] S609: The second node sends the perception measurement result to the first node; correspondingly, the first node receives the perception measurement result from the second node.

[0341] Optionally, in a case where the second request information further requests the timing error of the second node, in step S608 and step S609, the second node may further send the timing error of the second node.

[0342] Optionally, the timing error of the second node may include the value of the receiving or sending error. Specifically, the receiving or sending error refers to the error value or error range measured by the second node based on the reference value and the receiving measurement value or the sending measurement value, and the second node may report the error value or error range. The reference value may be a value configured or predefined by the first node or the second node. Further error value accuracy, such as microsecond or nanosecond values, may be configured or predefined by the first node or the second node. Optionally, one or more error values ​​or error ranges may be configured or predefined by the first node or the second node, and the second node may report an error index value or an error range index value.

[0343] The error corresponding to the timing measurement of the signals carried by a group of Tx beams and Rx beams can also be called a timing error group (TEG). The signals carried by the Tx beams and Rx beams applicable to the same timing error group can use the same hardware such as antennas and radio frequency units, and thus have the same combined timing error of transmission and reception. Exemplarily, when multiple transmission and reception time difference measurements of self-sensing signals are performed, the multiple measurements have the same timing error group. Further, the second node can report the error group value or error range. The reference value can be a value configured or predefined by the first node or the second node. Further, the accuracy of the error group value, such as a value at the microsecond or nanosecond level, can be configured or predefined by the first node or the second node. Optional one or more error group values ​​or error group ranges can be configured or predefined by the first node or the second node, and the second node can report the error group index value or the error group range index value.

[0344] Exemplarily, the timing error of the second node may include a maximum number of transceiver error groups TEG.

[0345] For example, the maximum number of TEGs is related to the number of TEGs supported by the second node; for example, the number of TEGs supported by the second node includes the maximum number of TEGs. The larger the maximum number of TEGs, the greater the signaling overhead of carrying the timing error.

[0346] Optionally, the timing error of the second node may include the number of different TEGs corresponding to the first signal. The number of different TEGs corresponding to the first signal refers to: the same Tx beam signal corresponds to multiple Rx beam signals. In this case, the different TEGs corresponding to the first signal perception measurement are the errors of the Tx beam corresponding to the multiple Rx beams. Specifically, the index ranges of the TEGs corresponding to the Tx and multiple Rx beams include but are not limited to: 0, 2, 3, 4, 6, and 8.

[0347] Optionally, the second request information may further indicate a timing error request mode, where the timing error request mode includes any one of an on-demand request, a periodic request, and a stop request. Furthermore, when the timing error request mode is a periodic request, the second request information may further indicate a timing error reporting period.

[0348] Exemplarily, the value of the reporting period of the timing error includes but is not limited to: 150 milliseconds, 320 milliseconds, 1280 milliseconds, 2560 milliseconds, and 737280 milliseconds.

[0349] Based on this example, parameters related to perception measurement, such as the perception measurement amount, may be indicated by the first node to the second node, so that the second node can implement perception measurement based on these parameters.

[0350] In a third possible implementation, when the perception measurement amount is indicated by the third node to the second node, the third node may indicate the perception measurement amount through third request information. The third request information is used to request a perception measurement result, and / or the third request information is used to indicate the perception measurement amount.

[0351] Optionally, the third request information may indicate one or more of the following: perception method, perception measurement time, expected value or measurement value range of perception measurement quantity, maximum number of transmission paths, number of reports of perception measurement results, reporting interval of perception measurement results, number of measurements of perception measurement results, measurement accuracy of perception measurement results, and number of samples of perception measurement results.

[0352] Exemplarily, the third request information may reflect the transmission characteristic requirements of transmit-receive separation perception or self-perception. For example, the third request information may implicitly indicate the transmission characteristic requirements of transmit-receive separation perception or self-perception through parameters such as the perception method, the perception measurement amount, the expected value of the perception measurement amount, or the measurement value range. Specifically, when the third request information passes through the perception method, the third request information may indicate the perception mode adopted by the perception method, thereby reflecting the transmission characteristic requirements of transmit-receive separation perception or self-perception. When the third request information passes through the perception measurement amount, and / or, the expected value or measurement value range of the perception measurement amount, the implementation of the perception mode indicated by the perception measurement amount can refer to the relevant description in the above embodiments and will not be repeated here.

[0353] The implementation of the above parameters can refer to the relevant description of the parameters in the above example, which will not be repeated here.

[0354] Optionally, because different second nodes may have different hardware configurations, resulting in different delays in sending and receiving the first signal, different second nodes may have different perceived delays. Therefore, the third request information may also request the timing error of the second node. This allows the third node to obtain the second node's delay, further improving perception accuracy.

[0355] Exemplarily, the implementation of the timing error of the second node can refer to the following related descriptions, which will not be repeated here.

[0356] In one implementation, the third request information from the third node may be forwarded to the second node through the first node.

[0357] For example, Figure 11 As shown in (a), before step S604, the communication perception method may further include the following steps S610 to S611:

[0358] S610: The third node sends third request information to the first node; correspondingly, the first node receives the third request information from the third node.

[0359] Exemplarily, step S610 may be performed before step S601, or after step S601, for example, after step S603. Alternatively, step S610 may be performed simultaneously with step S601, which is not limited in the present embodiment.

[0360] Exemplarily, the implementation of the third request information is similar to the implementation of the second request information. For details, please refer to the relevant description of the second request information above, which will not be repeated here.

[0361] S611: The first node sends third request information to the second node. Correspondingly, the second node receives the third request information from the first node.

[0362] Exemplarily, the implementation of step S611 is the same as the implementation of the above step S607. For details, please refer to the relevant description of the above step S607, which will not be repeated here.

[0363] In another implementation, the third request information from the third node may be directly sent to the second node.

[0364] For example, Figure 11 As shown in (b), before step S604, the communication perception method may further include the following step S612:

[0365] S612: The third node sends third request information to the second node; correspondingly, the second node receives the third request information from the third node.

[0366] Exemplarily, since the third node can learn about the second node after step S603 , step S612 can be performed after step S603 .

[0367] In combination with the above two implementation methods, optionally, after step S604, the communication perception method further includes step S608 or steps S608 to S609.

[0368] For example, the description of steps S608 to S609 may refer to the description of steps S608 to S609 above, which will not be repeated here.

[0369] Optionally, in a case where the third request information further requests the timing error of the second node, in step S608 and step S609, the second node may further send the timing error of the second node.

[0370] Optionally, the third request information may further indicate a timing error request mode, where the timing error request mode includes any one of an on-demand request, a periodic request, and a stop request. Furthermore, when the timing error request mode is a periodic request, the second request information may further indicate a timing error reporting period.

[0371] Exemplarily, the request mode of the timing error is stop, which means: stop requesting the timing error; exemplary, when the third request information indicates to stop requesting the timing error, the second node does not need to report the timing error when reporting.

[0372] For example, the implementation of the timing error related parameters (such as the timing error request method, the timing error reporting period, etc.) can refer to the related description in the above another example, which will not be repeated here.

[0373] Based on this possible implementation, the third node can directly indicate the perception measurement metric to the second node, allowing the second node to perform perception measurements based on the perception measurement metric. Furthermore, the third node can directly indicate the perception measurement metric to the second node without going through other nodes, thereby reducing signaling transmission latency and improving perception efficiency.

[0374] The above is an explanation of the parameters related to the perception measurement. The following is a detailed introduction to "the second node determines the perception measurement result based on the first configuration information" in the above step S604.

[0375] Exemplarily, based on different perception methods and different perception modes, step S604 can be implemented based on the following three situations:

[0376] Case 1: The perception mode is the self-perception mode.

[0377] For example, Figure 10 As shown, the communication perception method may further include the following steps S604A to S604C, that is, step S604 may be replaced by steps S604A to S604C:

[0378] S604A: The second node sends a first signal based on the first configuration information.

[0379] Optionally, the second node may send the first signal on the resource carrying the first signal (or the sending resource in the resource pair) indicated by the first configuration information.

[0380] S604B: The second node receives an echo signal of the first signal based on the first configuration information.

[0381] Optionally, the second node may receive the echo signal of the first signal on the resource (or the receiving resource in the resource pair) carrying the echo signal of the first signal indicated by the first configuration information.

[0382] S604C: The second node determines the perception measurement result.

[0383] Optionally, when the sensing method includes RTA sensing, the second node may further measure the reception time of the echo signal of the first signal. In this case, the sensing measurement result may include one or more of the transmission time of the first signal, the reception time of the echo signal of the first signal, and the transmission and reception time difference of the first signal.

[0384] Optionally, when the sensing method includes RTA sensing, the second node may further measure a reception angle of an echo signal of the first signal. In this case, the sensing measurement result includes one or more of the transmission angle of the first signal, the reception angle of the echo signal of the first signal, and a transmission / reception angle difference of the first signal.

[0385] Optionally, when the sensing method includes RTF sensing, the second node may further measure a reception frequency of an echo signal of the first signal. In this case, the sensing measurement result includes one or more of the transmission frequency of the first signal, the reception frequency of the echo signal of the first signal, and a difference between the transmission and reception frequencies of the first signal.

[0386] Exemplarily, the implementation of each parameter included in the perception measurement result may refer to the relevant description of the above embodiment, which will not be repeated here.

[0387] Optionally, after step S604C, the communication perception method further includes step S608 or steps S608 to S609.

[0388] For example, the description of steps S608 to S609 may refer to the description of steps S608 to S609 above, which will not be repeated here.

[0389] Case 2: The perception mode is a transmit-receive separation perception mode, and the perception method includes any one of RTA perception and RTF perception.

[0390] Optionally, in case 2, the first configuration information indicates at least two second nodes. For the convenience of description, two second nodes (ie, second node #1 and second node #2) are taken as an example for introduction below.

[0391] Optionally, in case 2, in step S602, the first node sends first configuration information to the second node #1 and the second node #2 respectively.

[0392] For example, Figure 12 As shown, the communication perception method may further include the following steps S604D to S604E, that is, step S604 may be replaced by steps S604D to S604E:

[0393] S604D: The second node #1 sends a first signal to the second node #2 based on the first configuration information; correspondingly, the second node #2 receives the first signal from the second node #1.

[0394] Optionally, the second node may send the first signal on the resource carrying the first signal indicated by the first configuration information. The second node #2 may receive the first signal from the second node #1 on the resource carrying the first signal indicated by the first configuration information.

[0395] S604E: The second node #2 determines the perception measurement result.

[0396] Optionally, when the sensing method includes RTA sensing, the second node #2 may measure the reception angle of the first signal. When the sensing method includes RTF sensing, the second node #2 may measure the reception frequency of the first signal.

[0397] In one implementation, when the sensing method includes RTA sensing, the sensing measurement result includes: a receiving angle of the first signal. When the sensing method includes RTF sensing, the sensing measurement result includes a receiving frequency of the first signal.

[0398] In another implementation, when the sensing method includes RTA sensing, second node #1 may inform second node #2 of the transmission angle of the first signal; thus, the sensing measurement result includes one or more of the transmission angle of the first signal, the reception angle of the first signal, and the difference between the transmission and reception angles of the first signal. When the sensing method includes RTF sensing, second node #1 may inform second node #2 of the transmission frequency of the first signal; thus, the sensing measurement result includes one or more of the transmission frequency of the first signal, the reception frequency of the first signal, and the difference between the transmission and reception frequencies of the first signal.

[0399] Exemplarily, the implementation of each parameter included in the perception measurement result may refer to the relevant description of the above embodiment, which will not be repeated here.

[0400] Optionally, after step S604E, the communication perception method further includes step S608 or steps S608 to S609, wherein step S608 may be replaced by the second node #2 sending the perception measurement result to the first node; and step S609 may be replaced by the second node #2 sending the perception measurement result to the third node.

[0401] For example, the description of steps S608 to S609 may refer to the description of steps S608 to S609 above, which will not be repeated here.

[0402] In addition, when the perception measurement result includes the reception angle of the first signal and / or the reception frequency of the first signal, after step S604E, the second node #2 may further send the perception measurement result to the second node #1, so that the second node #1 can update the perception measurement result and obtain an updated perception measurement result. Further, the second node #1 may send the updated perception measurement result to the first node and / or the third node. Exemplarily, when the perception method includes RTA perception, the updated perception measurement result includes: one or more of the transmission angle of the first signal, the reception angle of the first signal, and the transmission and reception angle difference of the first signal. When the perception method includes RTF perception, the updated perception measurement result includes one or more of the transmission frequency of the first signal, the reception frequency of the first signal, and the transmission and reception frequency difference of the first signal. Optionally, in case 1 and / or case 2, the perception measurement result is the perception measurement result corresponding to the first signal. Therefore, in case 1 and / or case 2, the perception measurement result in the above embodiment can be replaced with the perception measurement result corresponding to the first signal.

[0403] Case 3: The perception mode is a transmit-receive separation perception mode, and the perception method includes any one of RTT perception, RTA perception, and RTF perception.

[0404] Optionally, in case three, the first configuration information indicates at least two second nodes. For the convenience of description, two second nodes (ie, second node #1 and second node #2) are taken as an example for introduction below.

[0405] Optionally, in case three, in step S602, the first node sends first configuration information to the second node #1 and the second node #2 respectively.

[0406] Optionally, in case three, in addition to transmitting and receiving the first signal, the second node #1 and the second node #2 also need to transmit and receive the second signal. Therefore, before step S604, the second node #1 and the second node #2 also need to receive configuration information of the second signal.

[0407] Exemplarily, the implementation of the configuration information of the second signal is similar to the implementation of the first configuration information. For details, please refer to the relevant description of the first configuration information, which will not be repeated here.

[0408] Optionally, in case three, the second request information / the third request information may also be used to request perception measurement result #1 and / or perception measurement result #2.

[0409] For example, Figure 13 As shown, the communication perception method may further include the following steps S604F to S604I, that is, step S604 may be replaced by steps S604F to S604I:

[0410] S604F: The second node #1 sends the first signal to the second node #2 based on the first configuration information; correspondingly, the second node #2 receives the first signal from the second node #1.

[0411] Optionally, the second node #1 may send the first signal on the resource carrying the first signal indicated by the first configuration information.The second node #2 may receive the first signal from the second node #1 on the resource carrying the first signal indicated by the first configuration information.

[0412] S604G: The second node #2 determines the perception measurement result #1.

[0413] S604H: The second node #2 sends the second signal to the second node #1 based on the configuration information of the second signal; accordingly, the second node #1 receives the second signal from the second node #2.

[0414] Optionally, the second node #2 may send the second signal on the resource carrying the second signal indicated by the configuration information of the second signal.The second node #1 may receive the second signal from the second node #2 on the resource carrying the second signal indicated by the configuration information of the second signal.

[0415] S604I. The second node #1 determines the perception measurement result #2.

[0416] Exemplarily, steps S604F to S604G may be performed before steps S604H to S604I, or steps S604F to S604G may be performed after steps S604H to S604I, which is not limited in the embodiment of the present application.

[0417] In steps S604G and S604I above, optionally, if the sensing method includes RTT sensing, the second node #2 may measure the reception time of the first signal; and the second node #1 may measure the reception time of the second signal. If the sensing method includes RTA sensing, the second node #2 may measure the reception angle of the first signal; and the second node #1 may measure the reception angle of the second signal. If the sensing method includes RTF sensing, the second node #2 may measure the reception frequency of the first signal; and the second node #1 may measure the reception frequency of the second signal.

[0418] In one implementation, when the sensing method includes RTT sensing, sensing measurement result #1 includes: the reception time of the first signal and / or the transmission time of the second signal. Sensing measurement result #2 includes: the transmission time of the first signal and / or the reception time of the second signal.

[0419] When the sensing method includes RTA sensing, sensing measurement result #1 includes: a receiving angle of the first signal and / or a transmitting angle of the second signal. Sensing measurement result #2 includes: a transmitting angle of the first signal and / or a receiving angle of the second signal.

[0420] When the sensing method includes RTF sensing, sensing measurement result #1 includes the reception frequency of the first signal and / or the transmission frequency of the second signal. Sensing measurement result #2 includes: the transmission frequency of the first signal and / or the reception frequency of the second signal.

[0421] In one example, after step S604G and / or S604I, the second node #2 may report the perception measurement result #1 to the first node and / or the third node, and the second node #1 may report the perception measurement result #2 to the first node and / or the third node.

[0422] Specifically, the second node #2 reporting the perception measurement result #1 to the first node can be implemented based on step S608, that is, step S608 can be replaced by the second node #2 sending the perception measurement result #1 to the first node; the second node #2 reporting the perception measurement result #1 to the third node can be implemented based on step S609, that is, step S609 can be replaced by the second node #2 sending the perception measurement result #1 to the third node.

[0423] Similarly, the second node #1 reporting the perception measurement result #2 to the first node can be implemented based on step S613; the second node #1 reporting the perception measurement result #2 to the third node can be implemented based on step S614. Figure 13 As shown, after step S604I, the communication perception method further includes step S613 or steps S613-S614:

[0424] S613: The second node #1 sends the perception measurement result #2 to the first node; correspondingly, the first node receives the perception measurement result #2 from the second node #1.

[0425] S614. The second node #1 sends the perception measurement result #2 to the third node. Correspondingly, the third node receives the perception measurement result #2 from the second node #1.

[0426] Optionally, in this example, when the second node #2 reports the perception measurement result #1 to the first node, and the second node #1 reports the perception measurement result #2 to the first node, the first node may integrate the perception measurement result #1 and the perception measurement result #2 to obtain an integrated perception measurement result, and report the integrated perception measurement result to the third node. In other words, this step may replace steps S609 and S614.

[0427] Specifically, when the perception method includes RTT perception, the integrated perception measurement results may include: one or more of: the sending time of the first signal, the receiving time of the first signal, the first transceiver time, the sending time of the second signal, the receiving time of the second signal, the second transceiver time difference, and RTT (i.e., the time difference between the first transceiver time difference and the second transceiver time difference).

[0428] When the perception method includes RTA perception, the integrated perception measurement results may include: one or more of: the transmitting angle of the first signal, the receiving angle of the first signal, the first transceiver angle, the transmitting angle of the second signal, the receiving angle of the second signal, the second transceiver angle difference, and RTA (i.e., the angle difference between the first transceiver angle difference and the second transceiver angle difference).

[0429] When the perception method includes RTF perception, the integrated perception measurement results may include: one or more of: the sending frequency of the first signal, the receiving frequency of the first signal, the first transceiver frequency, the sending frequency of the second signal, the receiving frequency of the second signal, the second transceiver frequency difference, and RTF (i.e., the frequency difference between the first transceiver frequency difference and the second transceiver frequency difference).

[0430] In another example, after steps S604G and / or S604I, the second node #2 may send the perception measurement result #1 to the second node #1; thereby, the second node #1 may integrate the perception measurement result #1 with the perception measurement result #2 to obtain an integrated perception measurement result. Furthermore, the second node #1 may send the integrated perception measurement result to the first node and / or the third node. In this case, step S613 may be replaced with: the second node #1 sends the integrated perception measurement result to the first node; accordingly, the first node receives the integrated perception measurement result from the second node #1. Similarly, step S614 may be replaced with: the second node #1 sends the integrated perception measurement result to the third node; accordingly, the third node receives the integrated perception measurement result from the second node #1.

[0431] For example, the implementation of the integrated perception measurement results can be found in the relevant description in the above example, which will not be repeated here.

[0432] In another implementation, when the sensing method includes RTT sensing, second node #1 may inform second node #2 of the transmission time of the first signal, so that sensing measurement result #1 includes one or more of the transmission time of the first signal, the reception time of the first signal, the first transceiver time, and the transmission time of the second signal. Similarly, second node #2 may inform second node #1 of the transmission time of the second signal, so that sensing measurement result #2 includes one or more of the transmission time of the second signal, the reception time of the second signal, the second transceiver time, and the transmission time of the first signal.

[0433] When the sensing method includes RTA sensing, second node #1 may inform second node #2 of the transmission angle of the first signal; thus, sensing measurement result #1 includes one or more of the following: the transmission angle of the first signal, the reception angle of the first signal, the first transmission / reception angle difference, and the transmission angle of the second signal. Similarly, second node #2 may inform second node #1 of the transmission angle of the second signal; thus, sensing measurement result #2 includes one or more of the following: the transmission angle of the second signal, the reception angle of the second signal, the second transmission / reception angle difference, and the transmission angle of the first signal.

[0434] When the sensing method includes RTF sensing, second node #1 may inform second node #2 of the transmission frequency of the first signal; thus, sensing measurement result #2 includes one or more of the following: the transmission frequency of the first signal, the reception frequency of the first signal, the difference between the transmission and reception frequencies of the first signal, and the transmission frequency of the second signal. Similarly, second node #2 may inform second node #1 of the transmission frequency of the second signal; thus, sensing measurement result #2 includes one or more of the following: the transmission frequency of the second signal, the reception frequency of the second signal, the difference between the transmission and reception frequencies of the second signal, and the transmission frequency of the first signal.

[0435] Optionally, after step S604G and / or S604I, the second node #2 may send perception measurement result #1 to one or more of the second node #1, the first node, and the third node; similarly, the second node #1 may send perception measurement result #2 to one or more of the first node and the third node.

[0436] Optionally, when second node #2 sends perception measurement result #1 to second node #1, second node #1 may integrate perception measurement result #1 and perception measurement result #2 to obtain an integrated perception measurement result. Furthermore, the integrated perception measurement result may be reported to the first node and / or the third node. When second node #2 sends perception measurement result #1 to the first node, and second node #1 sends perception measurement result #2 to the first node, the first node may integrate perception measurement result #1 and perception measurement result #2 to obtain an integrated perception measurement result. Furthermore, the integrated perception measurement result may be reported to the third node.

[0437] Exemplarily, the implementation of each parameter included in the perception measurement result may refer to the relevant description of the above embodiment, which will not be repeated here.

[0438] Optionally, in case three, the perception measurement result may include the perception measurement result corresponding to the first signal and / or the perception measurement result corresponding to the first signal.

[0439] In one possible implementation, when the sensing mode is the transmit-receive separation sensing mode, in addition to the second node #1 and the second node #2 participating in the sensing in the above-mentioned scenario 2 and / or scenario 3, the first node and the second node may also participate in the sensing. In other words, the above-mentioned first node and the second node may replace the second node #1 and the second node #2, respectively.

[0440] For example, in scenario 2, the first node replaces the second node #1, and the second node replaces the second node #2. That is, the first node can send a first signal to the second node, and the second node receives the first signal to determine a perception measurement result. Furthermore, the perception measurement result can be sent to the first node or the third node. When the second node sends the perception measurement result to the first node, the first node can update the perception measurement result to obtain an updated perception measurement result. Furthermore, the first node can send the updated perception measurement result to the third node.

[0441] Specifically, the implementation of the perception measurement results and the updated perception measurement results may refer to the relevant description in the above situation 2, which will not be repeated here.

[0442] Alternatively, in case 2, the first node replaces the second node #2, and the second node replaces the second node #1; that is, the second node can send a first signal to the first node, and the first node receives the first signal, thereby determining the perception measurement result; further, the perception measurement result can be sent to the third node.

[0443] Specifically, the implementation of the perception measurement result is similar to the implementation of the updated perception measurement result in case 2. For details, please refer to the relevant description of the updated perception measurement result in case 2 above, which will not be repeated here.

[0444] For another example, in case three, the first node replaces the second node #1, and the second node replaces the second node #2; that is, the first node can send a first signal to the second node, and the second node receives the first signal, thereby determining the perception measurement result #1; further, the perception measurement result #1 can be sent to the first node or the third node. In addition, the second node also sends a second signal to the first node, and the first node receives the second signal, thereby determining the perception measurement result #2; further, the perception measurement result #2 can be sent to the third node. Among them, when the second node sends the perception measurement result #1 to the first node, the first node can integrate the perception measurement result #1 and the perception measurement result #2 to obtain an integrated perception measurement result, and further, the first node can send the integrated perception measurement result to the third node.

[0445] Alternatively, the first node replaces the second node #2, and the second node replaces the second node #1; that is, the second node can send a first signal to the first node, and the first node receives the first signal, thereby determining perception measurement result #1; further, perception measurement result #1 can be sent to a third node. Furthermore, the first node also sends a second signal to the second node, and the second node receives the second signal, thereby determining perception measurement result #2; further, perception measurement result #2 can be sent to the first node or the third node. When the second node sends perception measurement result #2 to the first node, the first node can integrate perception measurement result #1 and perception measurement result #2 to obtain an integrated perception measurement result, and further, the first node can send the integrated perception measurement result to the third node.

[0446] Specifically, the implementation of the perception measurement result #1, the perception measurement result #2, and the integrated perception measurement result may refer to the relevant description in the above situation three, which will not be repeated here.

[0447] For example, in this possible implementation, the second node may be a terminal device, and the first node may be a serving RAN node for the terminal device. Furthermore, when the first node transmits the first signal to the second node, the second node may also receive the first signal from another RAN node in addition to the first node. In this case, the perception measurement result #1 may also include the reception time of the first signal from the other RAN node, and / or the time difference between the reception time of the first signal from the first node and the reception time of the first signal from the other RAN node.

[0448] Similarly, when the first node sends the second signal to the second node, the second node may also receive the second signal from other RAN nodes other than the first node; in this case, the perception measurement result #2 may also include the reception time of the second signal from the other RAN node, and / or the time difference between the reception time of the second signal from the first node and the reception time of the second signal from the other RAN node.

[0449] The above embodiment can be applied to scenarios where the scheduling type is periodic scheduling. When the scheduling type is aperiodic scheduling or semi-persistent scheduling, the method is similar to the above, except that: before step S604, the third node may also send first indication information to the second node. The first indication information is used to activate the transmission of the first signal; and the first indication information is used to request perception of the measurement result (or request the second node to perform perception).

[0450] In one implementation, the first indication information from the third node may be forwarded to the second node through the first node.

[0451] For example, Figure 14 As shown in (a), before step S604, the communication perception method may further include the following steps S615 to S616:

[0452] S615. The third node sends first indication information to the first node; correspondingly, the first node receives the first indication information from the third node.

[0453] Exemplarily, since after step S603, the third node can obtain the first signal for sensing and the second node, step S615 can be performed after step S603, so that the third node can determine the first indication information.

[0454] S616: The first node sends first indication information to the second node. Correspondingly, the second node receives the first indication information from the first node.

[0455] Optionally, after step S616, the communication perception method may further include step S617: the first node sends response information to the third node for the first indication information, and accordingly, the third node receives the response information to the first indication information from the first node, wherein the response information to the first indication information indicates that transmission of the first signal has been activated.

[0456] Optionally, after step S609, the communication sensing method further includes the following steps S618 to S619:

[0457] S618: The third node sends second indication information to the first node; correspondingly, the first node receives the second indication information from the third node, wherein the second indication information indicates to deactivate transmission of the first signal.

[0458] S619: The first node sends second indication information to the second node. Correspondingly, the second node receives the second indication information from the first node.

[0459] In another implementation manner, the first indication information from the third node may be directly sent to the second node.

[0460] For example, Figure 14 As shown in (b), before step S604, the communication perception method may further include the following step S620:

[0461] S620: The third node sends first indication information to the second node; correspondingly, the second node receives the first indication information from the third node.

[0462] Exemplarily, since after step S603 , the third node can obtain the first signal for sensing and the second node; therefore, step S620 can be performed after step S603 .

[0463] Optionally, after step S609, the communication sensing method further includes step S621: the third node sends second indication information to the second node; accordingly, the second node receives the second indication information from the third node, wherein the second indication information indicates deactivation of transmission of the first signal.

[0464] In combination with the above two implementations, optionally, the first indication information may also be considered as an activation request for the first signal, and the activation request carries the above second request information / third request information.

[0465] Optionally, when the perception mode is a transmit-receive separation perception mode and the perception method includes RTT perception, the first indication information can also be used to activate the transmission of the second signal; correspondingly, the second indication information is also used to deactivate the transmission of the second signal.

[0466] Optionally, when the scheduling type is non-periodic scheduling, the first indication information can be carried in DCI; when the scheduling type is semi-persistent scheduling, the first indication information can be carried in MAC-CE.

[0467] Based on the above two implementation methods, since the first indication information is used to activate the transmission of the first signal; and the first indication information is used to request perception of the measurement result (or request the second node to perform perception), that is, the third node indicates two functions in the same signaling (that is, activating the transmission of the first signal and requesting perception of the measurement result), thereby reducing the signaling overhead.

[0468] In combination with the above embodiment, optionally, considering the problem of co-channel interference, the third node may avoid co-channel interference during the sensing communication process based on the following two scenarios:

[0469] Scenario 1: Considering the co-frequency interference of the first signal on one or more neighboring cells of the cell to which the first node belongs during the perception communication process.

[0470] Optionally, after receiving the response information of the first request information, the third node may send first configuration information to one or more neighboring RAN nodes before the second node sends the first signal or receives the first signal / the echo signal of the first signal; so that when the neighboring RAN nodes configure resources, they can avoid configuring resources that interfere with the resources indicated by the first configuration information, thereby improving perception efficiency.

[0471] Exemplarily, since the third node receives the response information of the first request information in step S603, and the second node sends the first signal or receives the first signal / an echo signal of the first signal in step S604, it can be considered that the step of the third node sending the first configuration information to one or more neighboring RAN nodes or terminal devices within the coverage of one or more neighboring RAN nodes can be performed after step S603 and before step S604.

[0472] For example, Figure 15 or Figure 16 As shown, after step S603 and before step S604, the communication perception method may further include the following step S622:

[0473] S622: The third node sends first configuration information to one or more RAN nodes in neighboring cells in a third time unit, and correspondingly, the one or more RAN nodes in the neighboring cells receive the first configuration information in the third time unit, where the third time unit is within the first time period.

[0474] Exemplarily, the first period may include the time between step S603 and step S604. Specifically, the start time of the first period is the time when the response information is sent; the end time of the first period is the time when the first signal is sent, or the end time of the first period is the time when the first signal or the echo signal of the first signal is received, or the end time of the first period is before the time when the first signal is sent.

[0475] Optionally, the first time period may be predetermined by the third node and notified to the second node. Figure 16 As shown, before step S601, the communication perception method may further include step S600C:

[0476] S600C: The third node sends third indication information to the first node; accordingly, the first node receives the third indication information from the third node, wherein the third indication information indicates the first time period.

[0477] Exemplarily, step S600C may be performed before step S600A, or step S600C may be performed after step S600A, or step S600C may be performed simultaneously with step S600A, which is not limited in the embodiment of the present application.

[0478] Exemplarily, when step S600C and step S600A are performed simultaneously, the first request information and the third indication information may be carried in the same signaling.

[0479] Optionally, the first node determines the first configuration information of the first signal, including: the first node determines the first configuration information based on a first time period.

[0480] Exemplarily, the first node may determine the resources carrying the first signal (or the sending resources in the resource pair) based on the first time period.

[0481] Scenario 2: Considering the co-channel interference from one or more neighboring cells of the cell to which the first node belongs during the perception communication process.

[0482] Optionally, the third node may send configuration information of a third signal of one or more neighboring cells that interferes with the first signal to the first node, so that the first node can configure and avoid the first configuration information that interferes with the first signal, thereby improving perception efficiency.

[0483] For example, Figure 17 As shown, before step S601, the communication perception method may further include the following step S600D:

[0484] S600D: The third node sends fourth indication information to the first node; correspondingly, the first node receives the fourth indication information from the third node, wherein the fourth indication information indicates configuration information of the third signal.

[0485] Exemplarily, step S600D may be performed before step S600A, or step S600D may be performed after step S600A, or step S600D may be performed simultaneously with step S600A, which is not limited in the embodiment of the present application.

[0486] Exemplarily, when step S600D and step S600A are performed simultaneously, the first request information and the fourth indication information may be carried in the same signaling.

[0487] Optionally, the first node determines the first configuration information of the first signal, including: the first node determines the first configuration information based on the configuration information of the third signal.

[0488] Exemplarily, the first node may determine the resources carrying the first signal and / or the echo signal of the first signal based on the resources in the configuration information of the third signal. For example, the resources carrying the first signal and / or the echo signal of the first signal do not include the resources in the configuration information of the third signal.

[0489] Optionally, the first node may further determine the first configuration information based on fifth request information, wherein the fifth request information is a perception request.

[0490] Specifically, such as Figure 18 As shown, before step S601, the communication perception method may include the following step S600E:

[0491] S600E: The first node obtains fifth request information.

[0492] Exemplarily, the fifth request information may come from a node with perception capability (such as the second node); or, the fifth request information may come from a third node; or, the fifth request information may come from the first node itself.

[0493] For example, the fifth request information can replace the above Figure 7 (a)~ Figure 17 Accordingly, the first node may respond to the fifth request information after step S604.

[0494] Optionally, the first node determines the first configuration information, including: the first node determines the first configuration information based on fifth request information.

[0495] In combination with the above embodiment, optionally, the first node determines the first configuration information, including: the first node determines the first configuration information based on perception capability information of one or more nodes with perception capability.

[0496] Optionally, the one or more nodes with perception capabilities include one or more second nodes.

[0497] Exemplarily, before step S601, the communication perception method may include the following step S600F:

[0498] S600F: One or more nodes with perception capabilities respectively send perception capability information to the first node. Correspondingly, the first node receives the perception capability information from the one or more nodes with perception capabilities.

[0499] Optionally, the perception capability information includes one or more of the following: signal type, duplex mode, perception measurement time, waveform carrying the first signal, maximum resource carrying the first signal, and perception method; wherein, the signal type includes one or more of perception signal, communication reference signal, and communication channel; the duplex mode includes half-duplex and / or full-duplex; the waveform includes one or more of single-carrier waveform, multi-carrier OFDM waveform, and FWCM; the perception mode includes one or more of self-perception mode and / or transmit-receive separation perception mode.

[0500] Exemplarily, the implementation of the signal type and the waveform carrying the first signal can refer to the relevant description of the above step S601, which will not be repeated here.

[0501] Optionally, the maximum resource carrying the first signal may include one or more resource sets capable of carrying the first signal, wherein the resource set includes one or more resources.

[0502] Optionally, when the perception mode includes the self-perception mode, the resources include sending resources and receiving resources; the capability information also indicates the duplex mode, and the duplex mode includes the full-duplex mode and / or the half-duplex mode; wherein, when the duplex mode includes the full-duplex mode, the sending resources and the receiving resources overlap; when the duplex mode includes the half-duplex mode, the time domain position of the receiving resources is located after the time domain position of the sending resources.

[0503] For example, taking the time domain position of the transmit resource as time unit #1 to time unit #2, in full-duplex mode, the time domain position of the receive resource may also be time unit #1 to time unit #2; or, the time domain position of the receive resource may be time unit #2 to time unit #3. In half-duplex mode, the time domain position of the receive resource may also be time unit #3 to time unit #4.

[0504] Exemplarily, resources including sending resources and receiving resources may also be referred to as resource pairs, that is, one or more resources are one or more resource pairs, or in other words, one or more resources include one or more resource pairs.

[0505] Optionally, the first node may indicate one or more resource sets capable of carrying the first signal based on the following two methods.

[0506] As an example, the sensing capability information indicates a maximum number of resource pairs within a frequency domain unit, wherein the one or more resources include one or more resource pairs, the resource pairs include a transmit resource and a receive resource corresponding to the transmit resource, and the frequency domain unit includes any one or more of the following: a frequency band, a carrier, or a bandwidth part (BWP).

[0507] Exemplarily, the frequency domain unit may be predefined by a protocol, or may be agreed upon in advance between the first node and the second node. Specifically, a frequency band may include one or more carriers, and a carrier may include one or more BWPs.

[0508] Exemplarily, the maximum number of resource pairs within a frequency domain unit may include, but is not limited to, any one of 1, 2, 4, 8, 12, and 16.

[0509] Optionally, the maximum number of resource pairs within the frequency domain unit includes: the maximum number of resource pairs of one or more carriers within the frequency band, and / or the maximum number of resource pairs of one or more BWPs within the carrier.

[0510] For example, taking the maximum number of resource pairs of one or more carriers within a frequency band as an example, when the frequency band is FR1, the value of the maximum number of resource pairs of one or more carriers within the frequency band includes but is not limited to any one of 6, 24, 64, 128, ..., 2048; when the frequency band is FR2, the value of the maximum number of resource pairs of one or more carriers within the frequency band includes but is not limited to any one of 24, 64, 96, 128, ..., 2048.

[0511] Optionally, the sensing capability information may further indicate a maximum number of first signals transmitted by each frequency domain unit.

[0512] Illustratively, the maximum number of first signals transmitted by each frequency domain unit may include, but is not limited to, any one of 1, 2, 4, 8, 12, 16, 32, and 64.

[0513] Optionally, one or more resource pairs may be combined into a resource pair set. In this case, the one or more resource sets may include one or more resource pair sets. The sensing capability information may indicate the maximum number of resource pairs in each resource pair set within the one or more resource pair sets. In other words, the sensing capability information indicates the maximum number of resource pairs required to form a resource pair set.

[0514] Illustratively, the maximum number of resource pairs in each resource pair set may include, but is not limited to, any one of 1, 2, 4, 8, 12, 16, 32, and 64.

[0515] As another example, the sensing capability information indicates the maximum number of resource pair sets in the same frequency layer and / or the maximum number of resource pairs in each resource pair set in the same frequency layer, wherein a resource pair includes a transmitting resource and a receiving resource corresponding to the transmitting resource.

[0516] For example, taking the maximum number of resource pairs in each resource pair set of the same frequency layer as an example, the value of the maximum number of resource pairs in each resource pair set of the same frequency layer may include but is not limited to any one of 6, 24, 32, 64, 96, 128, 256, 512, and 1024.

[0517] Exemplarily, the same frequency layer may include the frequency layer where nodes with sensing capabilities are located. Alternatively, the same frequency layer may include frequency layers with the same frequency value among multiple frequency layers; in this case, the sensing capability information may indicate the maximum number of resource pair sets in each frequency layer and / or the maximum number of resource pairs in each resource pair set in each frequency layer.

[0518] Optionally, a frequency layer is composed of one or more resource pair sets. Resource pairs (or resources) and / or resource pair sets (or resource sets) with the same frequency layer have the same point A.

[0519] Optionally, when the first signal is a chirp signal, the resource pairs (or resources) and / or resource pair sets (or resource sets) with the same frequency layer may also have one or more of the same chirp carrier, chirp subcarrier spacing (CCS), and chirp slope (chirp rate).

[0520] Exemplarily, the chirp slope refers to the ratio of the chirp bandwidth (or chirp carrier bandwidth or chirp subcarrier bandwidth) to the time corresponding to the chirp.

[0521] Optionally, when the first signal is an OFDM signal, resource pairs (or resources) and / or resource pair sets (or resource sets) with the same frequency layer may also have the same SCS and / or CP corresponding to the SCS.

[0522] Optionally, resource pairs (or resources) and / or resource pair sets (or resource sets) of different frequency layers may be located on the same carrier / BWP; or, resource pairs (or resources) and / or resource pair sets (or resource sets) of different frequency layers may be located on different carriers / BWPs.

[0523] Optionally, each resource pair or the SEB carrying the resource pair corresponds to a pair of transceiver beam pairs; wherein the transmitting resource in the resource pair corresponds to the Tx beam in the transceiver beam pair, and the receiving resource in the resource pair corresponds to the Rx beam in the transceiver beam pair.

[0524] For example, when the sensing mode includes the self-sensing mode, the polling pairing of the transceiver beams can be performed so that each resource pair or the SEB carrying the resource pair can correspond to the optimal transceiver beam pair, thereby improving the received signal strength.

[0525] Optionally, in order to enable the first node to determine the maximum amount of resources within a preset time period, the perception capability information may also indicate the maximum number of transmit and receive beam pairs / the maximum number of resource pairs (or SEBs carrying the resource pairs) within the preset time period.

[0526] Based on the above two examples, one or more nodes with perception capabilities can respectively indicate to the first node one or more resource sets supported by them for perception, so that the first node can configure a suitable resource set for perception, thereby improving perception efficiency.

[0527] Optionally, the sensing capability information may also indicate a maximum number of reference path loss signals. Further, the sensing capability information may include a parameter path loss signal. The reference path loss signal is used to determine the transmit power of the first signal.

[0528] Exemplarily, the relationship between the reference path loss information of the reference path loss signal and the transmission power of the first signal satisfies the above relationship (1). target PL reference , and PL reference The correlation factor alpha.

[0529] For example, P target The alpha can be indicated by the third node, or can be configured by the first node. reference is the path loss of the reference path loss signal.

[0530] Optionally, the maximum number of reference path loss signals refers to the maximum number of reference path loss signals simultaneously maintained by the serving cell and its neighboring cells to which the node with perception capability belongs.

[0531] Exemplarily, the maximum number of reference path loss signals includes, but is not limited to, 1, 4, 8, 16, and 32.

[0532] Specifically, the reference path loss signal and the first signal are in the same frequency band. The sensing capability information may further indicate whether open-loop power control of the reference path loss signal in the same frequency band as the first signal is supported. If the sensing capability information supports open-loop power control of the reference path loss signal in the same frequency band as the first signal, the first node may determine the transmit power of the first signal based on the reference path loss signal.

[0533] Exemplarily, the implementation of determining the transmit power of the first signal based on the reference path loss signal may refer to the above-mentioned description of the implementation of the transmit power of the first signal, which is not repeated here.

[0534] Exemplarily, the open-loop power control may be used in one or more of a connected state, a non-connected state (such as an inactive state or an idle state), and a low-power state.

[0535] Based on this optional solution, one or more sensing-capable nodes can indicate the maximum number of reference path loss signals used to determine the transmit power of the first signal. Furthermore, the reference path loss signals can be indicated. This enables the first node to determine the transmit power of the first signal based on the reference path loss signals, thereby enabling sensing measurements of the first signal. Furthermore, the maximum number of reference path loss signals is positively correlated with sensing performance; it is also positively correlated with storage capacity, detection capability, and power consumption capability.

[0536] Optionally, when the sensing mode includes the self-sensing mode, the sensing capability information may further indicate a maximum number of measurements of the sensing measurement quantity.

[0537] Exemplarily, when the perception method includes RTT perception, the maximum number of measurements of the perception measurement amount includes the maximum number of measurements of the parameters used to determine the RTT. Specifically, the different channel estimation capabilities of different signal types result in differences in signal processing time for different channel types. As a result, at the same time, the processing time of the signal is different from the processing time of the channel. For example, a signal (such as a perception signal or a communication reference signal) occupies 1 symbol, and a channel (such as a communication channel) occupies 1 slot. Therefore, under the same bandwidth and time constraints, the transmission time occupied by the channel transmission is usually greater than the transmission time occupied by the signal. As a result, the estimation performance of the perception measurement of the channel is better, and therefore, the value of the maximum number of measurements corresponding to the channel can be smaller than the value of the maximum number of measurements corresponding to the signal.

[0538] Similarly, when the perception method includes RTA perception, the maximum number of measurements of the perception measurement amount includes the maximum number of measurements of the parameters used to determine RTA. Specifically, the parameters for determining RTA may include the transmission angle (i.e., AOD) and / or the receiving angle (i.e., AOA) of the first signal. When the perception method includes RTF perception, the maximum number of measurements of the perception measurement amount includes the maximum number of measurements of the parameters used to determine RTF. Furthermore, the perception capability information may also indicate the frequency band range (such as FR1 or FR2 or FR3), the supported multipath capability (for example, the multipath capability supported within the device receiving time window), the maximum number of supported paths, and whether inactive state measurements are supported.

[0539] Optionally, when the perception mode includes a self-perception mode, the perception capability information may also indicate the maximum number of reference signals. Furthermore, the perception capability information may also indicate a reference signal. The spatial relationship and / or quasi-colocation (QCL) relationship corresponding to the reference signal is used to determine the correspondence between the transmit beam and the receive beam, the transmit beam is used to send the first signal, and the receive beam is used to receive the first signal or the echo signal of the first signal. That is to say, based on the spatial relationship and / or QCL relationship of the reference signal, the transceiver beam (or transceiver beam pair) corresponding to the resource pair (or resource) carrying the first signal can be determined.

[0540] Exemplarily, the transceiver beam (or transceiver beam pair) corresponding to the spatial relationship and / or QCL relationship of the reference signal can be used as the transceiver beam (or transceiver beam pair) corresponding to the resource pair (or resource) carrying the first signal.

[0541] Optionally, the maximum number of reference signals refers to the maximum number of reference signals simultaneously maintained by the serving cell to which the node with perception capability belongs and its neighboring cells.

[0542] Exemplarily, the reference signal may include one or more of the following: SERS, SSB, SRS, PRS, CSI-RS, WUS, and chirp.

[0543] Exemplarily, using QCL or spatial relationships can help reduce the reception detection complexity of the sensing node and help reduce the determination of transceiver beams. For example, the sensing node determines the transceiver beam of the first signal based on the beam of the received reference signal, simplifying the process of determining the transceiver beam. In the self-sensing mode, the received QCL parameters (i.e., the transmit QCL parameters and the receive QCL parameters) can be determined based on the spatial relationship. Furthermore, the transceiver spatial relationship (i.e., the transmit spatial relationship and the receive spatial relationship) or the transceiver beam can also be determined.

[0544] Optionally, the sensing capability information may also indicate the reciprocity capability of the Tx beam and the Rx beam. For example, the sensing capability information may indicate whether reciprocity of the Tx beam and the Rx beam is supported. Furthermore, the sensing capability information may also indicate reciprocity within the FR1 spectrum range (e.g., 410 MHz to 7125 MHz), reciprocity within the FR2 spectrum range (e.g., 24250 MHz to 52600 MHz), or beam reciprocity within a specific frequency band.

[0545] For example, the beam reciprocity capability can reduce the number of reference beams configured for the transmit and receive beams (the reference beam never determines the beam direction), thereby reducing signaling overhead.

[0546] Optionally, the sensing capability information may also indicate frequency band-based spatial filtering or spatial relationship processing capabilities. For example, the sensing capability information may indicate whether the reference signal maintained by the neighboring cell is supported as a QCL or Rx spatial association relationship; whether the reference signal maintained by the serving cell or the neighboring cell is supported as a Tx spatial filter association relationship; and whether the spatial association relationship configuration of the Tx beam or Rx beam is determined based on the angle offset configuration of the reference signal.

[0547] Exemplarily, the reference signals maintained by neighboring cells include, but are not limited to, one or more of SSB, SERS, PRS, CSI-RS, WUS, and chirp signals. The reference signals maintained by the serving cell or neighboring cells include, but are not limited to, one or more of SERS, PRS, SRS, preamble, and chirp signals.

[0548] Optionally, the perception capability information indicates the maximum processing time of the first signal; wherein the maximum processing time is greater than or equal to the maximum value of the maximum processing time of the perception signal, the maximum processing time of the communication reference signal, and the maximum processing time of the communication channel; or, the maximum processing time includes one or more of the following: the maximum processing time of the perception signal, the maximum processing time of the communication reference signal, and the maximum processing time of the communication channel.

[0549] Exemplarily, the maximum processing time may be understood as the ability of the node to process the first signal within a predetermined time.

[0550] Exemplarily, the maximum processing duration of a signal (such as a perception signal or a communication reference signal) is greater than or equal to the maximum of the maximum processing durations of different types of signals; or, the maximum processing duration of a signal includes the maximum processing durations of different types of signals. Similarly, the maximum processing duration of a channel (such as a communication channel) is greater than or equal to the maximum of the maximum processing durations of different types of channels; or, the maximum processing duration of a channel includes the maximum processing durations of different types of channels.

[0551] Optionally, the sensing capability information may also indicate the node's capability of measuring the first signal based on a specific number of measurements (such as 1 or 2 times) and / or the priority of the first signal.

[0552] Optionally, the sensing capability information may further indicate an offset value of a reception time window of the first signal. In this case, the reception time window of the first signal may include processing times of multiple transmission paths of echo signals of the first signal.

[0553] Optionally, the sensing capability information may further indicate the maximum number of resources (or resource pairs or beam pairs) processed per time slot (or per symbol block per SCS, or per subframe per SCS) under different SCSs. Exemplary values ​​for the maximum number of resources (or resource pairs or beam pairs) include, but are not limited to, 1, 2, 4, 48, and 64.

[0554] Optionally, the sensing capability information may further indicate a Tx beam (or Rx beam or transceiver beam pair) scanning factor. Exemplarily, the scanning factor may be any one of 1, 2, 4, and 6.

[0555] Optionally, the sensing capability information may further indicate one or more of a maximum bandwidth of the first signal, a buffering capability, and a reception time of the first signal. Exemplarily, the buffering capability may refer to buffering at a symbol level or a time slot level.

[0556] Specifically, the length of the reception time window required by a sensing-capable node varies depending on the sensing mode. Specifically, in the separate-transmitter-receiver sensing mode, the first signal is transmitted in a one-way manner. In the self-sensing mode, the first signal is transmitted to the target and then reflected back from the target, making the first signal transmission a round-trip process. Therefore, the transmission time of the first signal in the self-sensing mode is nearly twice that of the separate-transmitter-receiver sensing mode. Consequently, the length of the reception time window for the first signal varies depending on the sensing mode.

[0557] Optionally, the sensing capability information may further indicate the first signal cross-carrier processing capability. Exemplarily, the first signal cross-carrier processing capability includes one or more of the following: carrier configuration of aggregated bandwidth, maximum number of aggregated bandwidth carriers, and maximum aggregated bandwidth value.

[0558] Optionally, when the first signal is a chirp signal, the perception capability information also indicates one or more of the following: the maximum number of subcarriers of the chirp signal, the value range of the chirp signal slope (chirp rate), the number of chirp signal slopes, the maximum number of subcarriers of the chirp signal corresponding to the same chirp signal slope, and the maximum number of subcarriers of the chirp signal corresponding to different chirp signal slopes.

[0559] Exemplarily, the node's feedback on the number of subcarriers of the chirp signal and the chirp signal slope (chirp rate) enables the first node to configure different chirp subcarriers within the maximum chirp parameter range of the node, thereby performing low-power communication transmission or perception measurement feedback.

[0560] Optionally, the sensing capability information may further indicate a maximum chirp rate and / or a minimum chirp rate supported by the node.

[0561] Optionally, the perception capability information may further indicate a method for generating the first signal; wherein the generation method includes generating the first signal in a baseband unit; and / or generating the first signal in a baseband unit and a radio frequency unit.

[0562] Exemplarily, taking the first signal as a chirp signal as an example, a chirp analog signal can be generated in the radio frequency unit. Optionally, a modulation symbol such as a quadrature amplitude modulation (QAM) symbol or a phase modulation symbol can be superimposed (in product form) on the chirp analog signal to further improve transmission efficiency. By generating a chirp signal or an FMCW signal or a linear frequency modulation signal in the radio frequency unit, it is beneficial to reduce power consumption, that is, the node can transmit and receive signals with lower power consumption.

[0563] Optionally, the perception capability information may also indicate whether the node supports periodic reporting, whether it supports auxiliary information configuration, and the expected value or measurement value range of the perception measurement quantity. Specifically, when the perception method includes RTT perception, the measurement value range includes the reception time range of the first signal or the echo signal of the first signal; when the perception method includes RTA perception, the measurement value range includes the reception angle range of the first signal or the echo signal of the first signal; when the perception method includes RTF perception, the measurement value range includes the frequency offset range of the first signal or the echo signal of the first signal.

[0564] Exemplarily, the receiving time range includes a receiving time window or an uncertain time range. The receiving angle range includes any one of an uncertain beam range and an angle search window. The frequency offset range includes any one of an uncertain frequency offset range and a frequency offset search window. This can reduce detection complexity.

[0565] Optionally, the perception capability information may also indicate one or more of the expected value of the signal quality of the first signal, whether on-demand request for the first signal is supported, whether line of sight (LOS) / non-line of sight (NLOS) indication is supported, whether scheduling time-based perception request is supported, whether the valid area of ​​auxiliary data is supported, whether multiple measurement results are supported to be reported together, whether measurement gap activation request is supported, and the waveform of the first signal.

[0566] Exemplarily, the expected value of the signal quality of the first signal may be a minimum expected value, that is, the signal quality of the first signal is greater than or equal to the minimum expected value, so that the receiving capability of the node is improved.

[0567] The above embodiments are described using a terminal device / RAN node as the second node as an example. The second node may also be a sensor device. The following describes in detail the implementation of the communication perception process when the second node is a sensor device.

[0568] Optionally, the first node does not need to determine the first configuration message (further, does not need to determine the second configuration information). After receiving the fifth request information, it can directly send the fifth request information to one or more second nodes and receive response information to the fifth request information.

[0569] For the convenience of description, a second node is used as an example for introduction below. The implementation of multiple second nodes participating in perception is similar to the implementation of one second node described below. For details, please refer to the relevant description of the following embodiment, which will not be repeated here.

[0570] For example, Figure 19 As shown, the communication perception method may include the following steps S1901 to S1905:

[0571] S1901, wherein the implementation of step S1901 is the same as the implementation of the above-mentioned step S600E. For details, please refer to the relevant description of the above-mentioned step S600E, which will not be repeated here.

[0572] S1902: The first node sends fifth request information to the second node. Correspondingly, the second node receives the fifth request information from the first node.

[0573] Optionally, the first node may determine, based on the fifth request information, a second node that meets the perception requirements of the fifth request information; and then may send the fifth request information to the second node.

[0574] Optionally, the first node may determine the second node based on the sensing capability information of one or more sensing-capable nodes. That is, before step S1902, the first node may receive sensing capability information from one or more sensing-capable nodes, where the one or more sensing-capable nodes include the second node.

[0575] Exemplarily, the sensing capability information includes one or more of the following: the self-sensing capability of the sensor, the sensor type, and sensing requirement information.

[0576] Among them, sensor types include but are not limited to: one or more of: cameras, lidars, millimeter-wave radars, head-mounted displays, image sensors, video sensors, inertial sensors, and pressure sensors.

[0577] Perception requirement information includes but is not limited to: environmental detection capability, obstacle recognition capability, whether objects in a specific direction can be recognized, the type of objects, the size of objects, the distance of objects, etc.; one or more of the capabilities of direction / angle / distance / speed.

[0578] For example, the direction / angle / distance / speed capabilities may include one or more of: an angle range, a distance range, a speed range, accuracy, and a resolution of a specific direction.

[0579] S1903: The second node determines a perception measurement result.

[0580] Exemplary, the realization of the perception measurement results is similar to the above Figures 9 to 18 The realization of the perception measurement results in one or more of the embodiments described in Figures 9 to 18 The relevant description will not be repeated here.

[0581] S1904: The second node sends a perception measurement result to the first node; correspondingly, the first node receives the perception measurement result from the second node.

[0582] S1905. The first node responds to the fifth request information.

[0583] The above embodiment is an illustration of the node performing perception measurement (or a node with perception capability) as the second node. In fact, the node performing perception measurement may also include the first node; that is, the first node both determines the first configuration information and participates in the perception measurement.

[0584] Exemplarily, based on different sensing modes, the first node may perform sensing communication based on the following two situations:

[0585] Case 1: the perception mode is the self-perception mode.
