[0035] It should be understood that all or part of the functions of the communication device in this application can also be implemented through software functions running on hardware, or through virtualization functions instantiated on a platform (such as a cloud platform).

[0036] Wireless Sensing

[0037] Current cellular networks (such as 4G networks and 5G networks) are mainly used for wireless data transmission and communication. However, the radio electromagnetic wave signals used by cellular networks can not only be used for wireless data transmission and communication, but also have environmental perception capabilities. For example, radio electromagnetic wave signals can be used for user action / gesture recognition, breathing monitoring, terminal device movement speed measurement, environmental imaging, weather monitoring, etc. Therefore, in future communication systems (such as B5G systems, 6G systems, etc.), in addition to being used for data transmission and communication, cellular networks can also be used to perform perception services (or wireless perception services), such as obtaining perception information. The goal of wireless perception is to obtain perception results of the perception target, for example, obtaining a series of perception results such as the speed, distance, movement direction, shape, etc. of the perception target.

[0038] In order to support perception capabilities in a communication system, as an implementation method, a perception control function (SF) network element and corresponding processes can be added to the communication system. In this way, when the application layer (or application) sends a perception request for a perception target (for example, a target UE, a target object, etc.) to the core network, the core network can select a suitable access network device or auxiliary UE through the perception control network element or the access and mobility management function (AMF), and trigger the access network device or auxiliary UE to perform perception-related wireless measurement capabilities, start measuring perception information, and obtain perception results.

[0039] In some embodiments, to avoid introducing excessive air interface enhancements, the communication system may consider reusing existing air interface signals as much as possible to perform sensing services. For example, in the early stages of B5G interaural integration, existing air interface signals may be reused as much as possible to perform sensing services.

[0040] Awareness services can be performed using wireless sensing technology. Wireless sensing technology analyzes changes in wireless signals during propagation to determine the spatial characteristics of signal propagation, enabling environmental or scene perception. Given the similarities between wireless communication and wireless sensing, wireless communication and sensing technologies can be combined to simultaneously achieve communication and perceive the surrounding environment. In some embodiments, this combination of wireless communication and sensing technologies can be understood as synaesthesia integration.

[0041] There are many wireless sensing scenarios for synaesthesia integration. The following is an illustrative introduction to the main wireless sensing scenarios for synaesthesia integration with reference to Figures 2A to 2F. It should be noted that the following scenarios are merely examples, and the technical solutions of this application can be applied to the following scenarios. However, the following scenarios are not intended to limit the technical solutions of this application, and this application is still applicable to other application scenarios.

[0042] See Figure 2A, which is a schematic diagram of an application scenario provided by an embodiment of the present application. Figure 2A is an example of a situation where a base station in a communication system serves as both a transmitter and a receiver of a perception signal. Therefore, the perception link corresponding to Figure 2A can also be referred to as a base station echo perception link. In Figure 2A, the base station can send a perception signal, which is reflected back to the base station by a perception target (for example, a car in the surrounding environment). In this way, the base station can perform perception measurements on the perception signal to obtain a perception result.

[0043] Refer to Figure 2B, which is a schematic diagram of another application scenario provided by an embodiment of the present application. Figure 2B is an example of a situation where two base stations serve as the transmitter and receiver of the perception signal, respectively. Therefore, the perception link corresponding to Figure 2B can also be called an inter-base station perception link. In Figure 2B, base station A can send a perception signal, and the perception signal is reflected by the perception target (for example, a car in the surrounding environment) to base station B. In this way, base station B can perform perception measurement on the perception signal and obtain a perception result.

[0044] Refer to Figures 2C and 2D, which are schematic diagrams of another application scenario provided by an embodiment of the present application. Figures 2C and 2D are examples of a situation where the base station and the UE serve as the transmitter and receiver of the perception signal, respectively. Therefore, the perception links corresponding to Figures 2C and 2D can also be referred to as air interface perception links. Figure 2C is an example of an air interface uplink perception link. In Figure 2C, the UE can send a perception signal, and the perception signal is reflected to the base station by a perception target (for example, a car in the surrounding environment). In this way, the base station can perform perception measurement on the perception signal and obtain a perception result. Figure 2D is an example of an air interface downlink perception link. In Figure 2D, the base station can send a perception signal, and the perception signal is reflected to the UE by a perception target (for example, a car in the surrounding environment). In this way, the UE can perform perception measurement on the perception signal and obtain a perception result.

[0045] See Figure 2E, which is a schematic diagram of another application scenario provided by an embodiment of the present application. Figure 2E is an example of a situation where a UE in a communication system serves as both a transmitter and a receiver of a perception signal. Therefore, the perception link corresponding to Figure 2E can also be referred to as a UE echo perception link. In Figure 2E, the UE can transmit a perception signal, which is reflected back to the UE by a perception target (e.g., a car in the surrounding environment). In this way, the UE can perform perception measurements on the perception signal to obtain a perception result.

[0046] See Figure 2F, which is a schematic diagram of another application scenario provided by an embodiment of the present application. Figure 2F is an example of a situation where two UEs serve as the transmitter and receiver of a perception signal, respectively. Therefore, the perception link corresponding to Figure 2F can also be referred to as an inter-UE perception link. In Figure 2F, UE A can transmit a perception signal, which is reflected by a perception target (e.g., a car in the surrounding environment) to UE B. In this way, UE B can perform perception measurements on the perception signal and obtain a perception result.

[0047] Beamforming

[0048] Beamforming is a new technology introduced in 5G. After the introduction of beamforming, both base stations and terminal devices can use beams with concentrated energy in a specific spatial direction to send and receive communication signals.

[0049] Because beamforming narrows the coverage of a beam, the base station and terminal device need to determine a transmit / receive beam pair to successfully receive or transmit communication signals in a specific direction. To determine the "beam pair" of the transmitter's transmit beam and the receiver's receive beam, for example, the "beam pair" for the base station's downlink transmission and the UE's receive beam, the transmitter and receiver can each determine the "optimal transmit / receive beam pair" using beam scanning. As an implementation method, the transmitter and receiver can determine the "optimal transmit / receive beam pair" using the following implementation method.

[0050] In step 1, given the receiving end beam, the transmitting end beam is scanned, and the receiving end can determine the candidate transmitting beam based on the measured reference signal received power (RSRP) of multiple transmitting beams and report it to the transmitting end.

[0051] In step 2, given the transmitting end beam, the receiving end beam is scanned, and the receiving end can determine the candidate receiving beam based on the RSRP of the transmitting beam measured by multiple receiving beams and report it to the transmitting end.

[0052] In some embodiments, the base station may use a beam with a constant direction to send a communication signal (eg, a reference signal) to the UE multiple times. In some embodiments, the base station may use different beams to send a communication signal to the UE.

[0053] As an implementation method, the UE can determine whether the base station uses a beam with a constant direction or different beams to send communication signals based on the NZP-CSI-RS-ResourceSet information element (IE). For example, when the base station sets the repetition IE in the NZP-CSI-RS-ResourceSet to "off", the UE knows that the base station uses different beams when sending communication signals; conversely, when the base station sets the repetition IE to "on", the UE knows that the base station uses a beam with a constant direction when sending communication signals.

[0054] The NZP-CSI-RS-ResourceSet IE is a set of non-zero-power (NZP) channel state information reference signal (CSI-RS) resources (i.e., NZP CSI-RS IDs) and group-level parameters. For ease of understanding, an example of the NZP-CSI-RS-ResourceSet IE is provided below.

[0055] If the base station informs the UE in the reference signal configuration sent to the UE that the transmit beams of multiple NZP CSI-RS resources in a certain resource set are changing, then when the UE receives this information, the UE can start scanning the transmit beam (the receive beam does not change) to determine the optimal transmit beam. Subsequently, when the repetition IE in the NZP-CSI-RS-ResourceSet IE is set to "on", the UE can scan the receive beam to determine the optimal receive beam. Based on this, the best transmit and receive beam pair can be determined between the base station and the UE. In some embodiments, based on channel reciprocity, the beam with the best received signal quality can also be used as the beam for data transmission.

[0056] Beam pointing

[0057] If multiple transmit and receive antenna pairs are maintained between the UE and the base station, the base station can select which transmit antenna to use when transmitting the physical downlink shared channel (PDSCH) or physical downlink control channel (PDCCH). In this case, the base station can send this information to the UE so that the UE can switch to the receive antenna that matches the base station's selected transmit antenna. This mechanism is called beam indication. In other words, the base station can send beam indication information to the UE so that the UE can determine the appropriate receive beam.

[0058] In some embodiments, beam indication can be implemented using the transmission configuration indicator (TCI) state and quasi-co-location (QCL) concept. As an implementation, the base station can configure a set of TCI states for the UE via higher-layer signaling. The base station can then send TCI activation signaling to the UE, allowing the UE to determine the TCI state ID corresponding to the received PDCCH or PDSCH, and thus determine the beam information for the received PDCCH or PDSCH.

[0059] In some embodiments, each TCI state in a set of TCI states configured by the base station for the UE corresponds to a set of reference signals, such as CSI-RS or synchronization information block (synchronization signal / PBCH block, SSB) ID, to indicate that the characteristics of the spatial filtering (or beam) of the PDSCH and PDCCH transmissions match one of the above reference signals.

[0060] As an implementation, the TCI state may include one or more of the following configurations: a TCI state identifier (ID); QCL information 1; and QCL information 2. The TCI state ID may be used to identify the TCI state. The QCL information (e.g., QCL information 1, QCL information 2, etc.) may include: a QCL type configuration and a QCL reference signal configuration.

[0061] In some embodiments, the QCL type configuration may be one of QCL type A, QCL type B, QCL type C, or QCL type D. However, the embodiments of the present application are not limited thereto, and when the QCL type includes other types, the QCL type configuration may also be other types.

[0062] In some embodiments, the QCL reference signal configuration may include one or more of the following information: a cell ID where the reference signal resides, a bandwidth part (BWP) ID, and a reference signal identifier. For example, if the reference signal is a CSI-RS or SSB, the reference signal identifier may be, for example, a CSI-RS resource identifier or an SSB number.

[0063] As an implementation method, the TCI-State IE can associate one or two downlink reference signals with the corresponding QCL type to utilize the TCI state for beam indication.

[0064] For ease of understanding, an example of TCI-State IE is given below.

[0065] Activate / deactivate TCI status

[0066] The network may activate and deactivate the TCI state configured for the PDSCH of a serving cell or a group of serving cells by sending a UE-specific TCI state activation / deactivation medium access control element (MAC CE) for PDSCH, where the TCI state is configured via the simultaneousTCI-UpdateList1 or simultaneousTCI-UpdateList2 field. The network may activate and deactivate the TCI state configured for the codepoint of the downlink control information (DCI) transmission configuration indication field indicated by the PDSCH of a serving cell by sending a UE-specific enhanced TCI state activation / deactivation MAC CE for PDSCH. The TCI state configured for PDSCH is deactivated after upper layer (re)configuration and synchronous reconfiguration.

[0067] During the activation / deactivation process of the TCI state, the MAC entity should perform the following steps.

[0068] 1> If the MAC entity receives a TCI state activation / deactivation MAC CE for UE-specific PDSCH in the serving cell:

[0069] 2> The MAC entity indicates to the lower layer information about the TCI state activation / deactivation MAC CE of the UE-specific PDSCH.

[0070] 1> If the MAC entity receives an enhanced TCI state activation / deactivation MAC CE for UE-specific PDSCH in the serving cell:

[0071] 2> The MAC entity indicates to the lower layer information about the enhanced TCI state activation / deactivation MAC CE of the UE-specific PDSCH.

[0072] As mentioned above, cellular networks can be used to perform perception services. In scenarios where cellular networks are used to perform perception services, the transmitter / receiver of the perception signal needs to send or receive the perception signal on a beam. Therefore, how the transmitter / receiver determines the beam for sending or receiving the perception signal is a problem that needs to be solved. Especially in mobile scenarios, the relative position between the transmitter / receiver of the perception signal and the perception target may change, and the beam used to send or receive the perception signal also needs to be adjusted accordingly. Therefore, how to determine the beam for sending or receiving the perception signal when the transmitter / receiver is in different positions remains an urgent problem that needs to be solved.

[0073] In response to the above problems, the embodiments of the present application provide a method and apparatus for wireless communication, so that the transmitter / receiver of the perception signal can determine the first beam for sending / receiving the perception signal based on the first information, which is conducive to ensuring that the determined first beam is more accurate, thereby providing the basic conditions for the first beam to better rush toward the perception target.

[0074] The method embodiment of the present application is described in detail below with reference to FIG3 to FIG6 .

[0075] Figure 3 is a flow chart of a wireless communication method provided by an embodiment of the present application. The method shown in Figure 3 is described from the perspective of the interaction between a first communication device and a second communication device. The first communication device and the second communication device are first introduced separately.

[0076] The first communication device refers to the transmitter or receiver of the perception signal. In other words, the first communication device can transmit or receive the perception signal. Furthermore, the first communication device can also be understood as the receiver of the first information mentioned below. The second communication device refers to the transmitter of the first information.

[0077] In some embodiments, if the first communication device is a transmitter of the perception signal, the second communication device may be a receiver of the perception signal, that is, the receiver of the perception signal may send the first information to the transmitter of the perception signal.

[0078] In some embodiments, if the first communication device is a receiving end of the perception signal, the second communication device may be a sending end of the perception signal, that is, the sending end of the perception signal may send the first information to the receiving end of the perception signal.

[0079] However, the embodiments of the present application are not limited thereto. The first information may also be sent to the first communication device by a communication device other than the sender / receiver of the perception signal. That is, the second communication device may also be a communication device other than the sender / receiver of the perception signal. For example, the second communication device may be a core network device, such as an AMF network element or a SF network element.

[0080] In some embodiments, the first communication device may be a terminal device (e.g., the terminal device 120 shown in FIG1 ), and the second communication device may be one of the following: an access network device (e.g., the access network device 110 shown in FIG1 ), a core network device, or a terminal device. For example, where the sender and receiver of the perception signal are a terminal device and an access network device (e.g., the terminal device sends the perception signal to the access network device, or the access network device sends the perception signal to the terminal device), in some embodiments, the access network device may send first information to the terminal device so that the terminal device determines a beam for sending or receiving the perception signal (i.e., the first beam hereinafter); in some embodiments, the core network device may send the first information to the terminal device so that the terminal device determines a beam for sending or receiving the perception signal. For example, where both the sender and receiver of the perception signal are terminal devices, in some embodiments, the access network device or the core network device may send the first information to the terminal device; in some embodiments, the terminal device sending the perception signal may send the first information to the terminal device receiving the perception signal, or the terminal device receiving the perception signal may send the first information to the terminal device sending the perception signal.

[0081] In some embodiments, the first communication device may be an access network device (for example, the access network device 110 shown in FIG1 ), and the second communication device may be one of the following: an access network device, a core network device. Taking the example that the sending end and the receiving end of the perception signal are a terminal device and an access network device (for example, the terminal device sends a perception signal to the access network device, or the access network device sends a perception signal to the terminal device), in some embodiments, the core network device may send first information to the access network device so that the access network device determines the beam for sending or receiving the perception signal. Taking the example that both the sending end and the receiving end of the perception signal are access network devices, in some embodiments, the core network device may send the first information to the access network device; in some embodiments, the access network device that sends the perception signal may send the first information to the access network device that receives the perception signal, or the access network device that receives the perception signal may send the first information to the access network device that sends the perception signal.

[0082] The core network devices mentioned in the embodiments of this application may be of various types, and the embodiments of this application are not limited thereto. For example, in some embodiments, the core network device may be a SF network element. Alternatively, in some embodiments, the core network device may be an AMF network element, etc.

[0083] The method shown in FIG3 includes step S310 , which is described below.

[0084] In step S310, a first communication device receives first information, where the first information is used to determine a first beam.

[0085] The first beam can be used to send or receive a sensing signal, that is, the first beam is a beam used to send or receive a sensing signal. In other words, the first beam can be used to perform a sensing service.

[0086] In some embodiments, the beam (e.g., the first beam) mentioned in the embodiments of the present application may also be referred to as a spatial domain filter, a spatial domain parameter, or other names. For ease of understanding, the embodiments of the present application mainly use the beam as an example, and the beam, spatial domain filter, spatial domain parameter, etc. can be used interchangeably.

[0087] In some embodiments, the first beam may be different from a beam through which the first communication device transmits / receives communication signals.

[0088] In some embodiments, the first beam may be the same beam as the beam by which the first communication device transmits / receives communication signals.

[0089] In the embodiment of the present application, the first beam is determined using the first information. The first communication device determines the first beam based on the first information, which helps ensure that the determined first beam is more accurate, thereby providing a basic condition for the first beam to better strike the sensing target.

[0090] In some embodiments, the first information may be sent from the second communication device to the first communication device.

[0091] In some embodiments, the first information may be used to indicate the first beam. For example, the first information may include first beam indication information corresponding to the first beam. In this way, the first communications device may determine the first beam for transmitting or receiving the perception signal based on the first beam indication information.

[0092] In some embodiments, the first information may be used to indicate the location information of the sensing target. In some embodiments, the sensing target (e.g., sensing UE, sensing object, etc.) may also be referred to as a sensed target, a target to be sensed, or other names, which are not limited in the embodiments of the present application.

[0093] For ease of understanding, the following describes the first information in detail in combination with Example 1 and Example 2, taking the first information used to indicate the first beam and the first information used to indicate the position information of the perceived target as examples.

[0094] Example 1:

[0095] In the first embodiment, the first information may be used to indicate the first beam. As an implementation, the first information may use beam indication information to indicate the first beam. For example, the first information may include first beam indication information corresponding to the first beam, so that the first beam is indicated to the first communication device via the first beam indication information.

[0096] In some embodiments, the first information is different from the second beam indication information for sending or receiving communication signals by the first communication device. In other words, the first beam indication information is different from the second beam indication information for sending or receiving communication signals by the first communication device. In this way, the second communication device can configure the first communication device with beam indication information separately for sending or receiving perception signals through the first information, or configure the first communication device with (independent) beam indication information different from that used for sending or receiving communication signals through the first information, so as to avoid the problem of poor transmission performance caused by using the beam indication information for sending or receiving communication signals to send or receive perception signals. Taking the terminal device and the access network device performing perception services as an example, when the spatial relationship between the terminal device and the access network device is different from the spatial relationship between the perception target and the terminal device, the second communication device (for example, the access network device) can configure the first communication device (for example, the terminal device) with separate beam indication information for performing perception services to improve transmission performance.

[0097] In some embodiments, the first information is the same as the second beam indication information for the first communication device to send or receive communication signals. In other words, the first beam indication information is the same as the second beam indication information for the first communication device to send or receive communication signals. In this way, the first communication device can reuse the beam used to send or receive communication signals to send or receive perception signals. Taking the terminal device and the access network device performing a perception service as an example, when the spatial relationship between the terminal device and the access network device is the same as the spatial relationship between the perception target and the terminal device, the terminal device can reuse the second beam indication information indicated by the access network device to save signaling overhead.

[0098] In some embodiments, the first beam indication information may be indicated using a TCI state. For example, the first beam indication information may include one or more of the following configurations: a TCI state ID, an identifier of a QCL reference signal, and a QCL type.

[0099] In some embodiments, the QCL reference signal may be identified by using an SSB number. In some embodiments, the QCL reference signal may be identified by using a CSI-RS identifier, which is not limited in this embodiment of the present application.

[0100] The embodiment of the present application does not limit the manner in which the first information is carried. For example, the first information may be carried in one or more of the following: non-access stratum (NAS) signaling, radio resource control (RRC) signaling, MAC CE signaling, and an interface between access network devices.

[0101] The embodiment of the present application does not limit the specific type of NAS signaling. For example, the NAS signaling can be a signal awareness assistance message. That is, the second communication device can send the first information to the first communication device via the signal awareness assistance message.

[0102] The embodiment of the present application does not specifically limit the interface between access network devices. For example, the interface between access network devices may be, for example, an Xn interface or an NG interface.

[0103] As an example, the first communication device is a terminal device and the second communication device is an access network device, then the first information can be carried in RRC signaling or MAC CE signaling.

[0104] As another example, the first communication device is a terminal device and the second communication device is a core network device, then the first information can be carried in NAS signaling.

[0105] As another example, the first communication device and the second communication device are both access network devices, and the first information can be transmitted through an interface between the access network devices.

[0106] In some embodiments, the first information may be preconfigured. For example, the first information may be preconfigured by the second communication device.

[0107] In some embodiments, the first information may include beam indication information, which is referred to as first beam indication information. In this case, after receiving the first information, the first communications device may determine the first beam based on the first beam indication information, or may send or receive the perception signal based on the first beam corresponding to the first beam indication information.

[0108] In some embodiments, the first information may include multiple candidate beam indication information, or in other words, the first information may include a candidate beam set or a candidate beam list. The multiple candidate beam indication information includes first beam indication information corresponding to the first beam, that is, the first beam indication information belongs to the multiple candidate beam indication information.

[0109] In some embodiments, when the first information includes multiple candidate beam indication information, the first communication device may further determine the first beam indication information corresponding to the first beam based on the second information. This will be described below with reference to FIG4 .

[0110] FIG4 is a flow chart of a wireless communication method according to another embodiment of the present application. As shown in FIG4 , the method may include step S410 and step S420.

[0111] In step S410, a first communication device receives first information, which is used to determine a first beam.

[0112] The first information includes multiple candidate beam indication information. In other words, the first information can be used to indicate or configure multiple candidate beam indication information.

[0113] For other descriptions of the first information and the first beam in step S410, please refer to the above introduction to step S310, which will not be repeated here for the sake of brevity.

[0114] In step S420, the first communication device receives second information, where the second information is used to indicate the first beam indication information.

[0115] That is, when the first information indicates multiple candidate beam indication information, the second information can be used to activate one or more of the multiple candidate beam indication information as the first beam indication information corresponding to the first beam.

[0116] The embodiment of the present application does not limit the carrying method of the second information. For example, the second information can be carried in the first signaling, and the first signaling can include one or more of the following: MAC CE signaling, RRC signaling, sidelink control information (SCI), and an interface between access network devices.

[0117] As an example, if the first communication device is a terminal device and the second communication device is an access network device, the second information may be carried in MAC CE signaling or RRC signaling. However, the embodiment of the present application is not limited thereto, for example, the second information may also be carried in DCI.

[0118] As another example, the first communication device and the second communication device are both terminal devices, and the second information can be carried in the SCI.

[0119] As another example, the first communication device and the second communication device are both access network devices, and the second information can be transmitted through an interface between the access network devices.

[0120] In some embodiments, the second information may be sent from the second communication device to the first communication device. That is, in some embodiments, the first information and the second information may be sent from the same communication device to the first communication device.

[0121] In some embodiments, the second information may use a TCI state ID to indicate the first beam indication information.

[0122] In some embodiments, the signaling carrying the second information may be configured separately. Taking the signaling carrying the second information as MAC CE signaling as an example, the second communication device may configure a separate MAC CE signaling to indicate the first beam indication information.

[0123] In some embodiments, the signaling used to configure the first beam indication information is different from the signaling used to configure the second beam indication information (the second beam indication information is used to indicate the beam for the first communications device to transmit or receive communications signals). For example, the signaling used to configure the first beam indication information may be MAC CE signaling, and the signaling used to configure the second beam indication information may be RRC signaling. Alternatively, the signaling used to configure the first beam indication information and the signaling used to configure the second beam indication information may both be MAC CE signaling, but the two are different MAC CE signaling.

[0124] In some embodiments, the signaling used to configure the first beam indication information and the signaling used to configure the second beam indication information are different, which can be understood as the signaling used to configure the first beam indication information and the signaling used to configure the second beam indication information corresponding to different logical channel numbers. For example, if the signaling used to configure the first beam indication information and the signaling used to configure the second beam indication information are both MAC CE signaling, the two may have different logical channel numbers.

[0125] In some embodiments, the acquisition or update of the first information may be performed based on a request from the first communication device. FIG5 is a flowchart of a wireless communication method provided by another embodiment of the present application. Referring to FIG5 , the method of FIG5 may include steps S510 and S520.

[0126] In step S510, a first communication device sends a first request for acquiring or updating first information.

[0127] In some embodiments, the first request may be sent by the first communication device to the second communication device.

[0128] In some embodiments, the first request may be carried in one or more of the following signaling: MAC CE signaling, NAS signaling, RRC signaling, SCI, and an interface between access network devices. Taking the first communication device as a terminal device and the second communication device as an access network device as an example, the first request may be carried in uplink MAC CE signaling or uplink RRC signaling. Of course, in some embodiments, the first request may also be carried in uplink control information (UCI). Taking the first communication device as a terminal device and the second communication device as a core network device as an example, the first request may be carried in uplink NAS signaling.

[0129] In some embodiments, the first request for obtaining or updating the first information may refer to the first request for obtaining or updating a plurality of candidate beam indication information. In some embodiments, the first request for obtaining or updating the first information may refer to the first request for obtaining or updating the beam indication information currently applied by the first communication device (i.e., the first beam indication information).

[0130] In some embodiments, after receiving the first request sent by the first communication device, the second communication device can send or update first information for the first communication device, such as updating multiple candidate beam indication information, or updating the beam indication information currently applied by the first communication device.

[0131] In various situations, the first communication device may send a first request to obtain or update the first information. The embodiments of the present application do not specifically limit the situation in which the first communication device sends the first request. For example, the first communication device may send the first request when the channel state changes or the state of the first communication device changes.

[0132] As an example, when the channel state changes or the change is greater than a certain threshold, the first communication device may send a first request. The embodiment of the present application does not limit the type of change in the channel state. For example, when the line of sight (LOS) of the perception signal received through a certain channel deteriorates (for example, the LOS value indicates a decrease), the first communication device may send a first request.

[0133] As another example, when the state of the first communication device changes or changes by more than a certain threshold, the first communication device may send a first request. The embodiment of the present application does not limit the type of state change of the first communication device. For example, when the position of the first communication device changes or changes by more than a certain threshold, the first communication device may send a first request; or when the reference signal receiving power (RSRP) of the serving cell of the first communication device changes or changes by more than a certain threshold, the first communication device may send a first request, etc.

[0134] In step S520, the first communication device receives first information.

[0135] For a detailed description of step S520, please refer to the above description of step S310 or step S410, which will not be repeated here for the sake of brevity.

[0136] In some embodiments, when the first information includes multiple candidate beam indication information, the first communications device may further receive second information indicating the first beam indication information. Alternatively, the second information may indicate activation of the first beam indication information or activation of the beam corresponding to the first beam indication information (the first beam).

[0137] In some embodiments, the second communication device may update the first information, for example, proactively updating the first information. As an implementation, the second communication device may update the first information (for example, updating the multiple candidate beam indication information of the first communication device, or updating the beam indication information currently used by the first communication device) through immediate RRC signaling or MAC CE signaling.

[0138] In some embodiments, the change or update of the first beam (or, the change or update of the first information) occurs when the relative position between the first communication device and the sensing target changes. For example, the change or update of the first beam occurs when the position of the first communication device changes. For another example, the change or update of the first beam occurs when the position of the sensing target changes. For another example, the change or update of the first beam occurs when the positions of both the first communication device and the sensing target change.

[0139] In some embodiments, the beam indication information used to send or receive the perception signal may be associated with multiple types of information. For example, the beam indication information used to send or receive the perception signal may be associated with (correspond to) one or more of the following: geographic location information, and time domain resource information.

[0140] In some embodiments, it can also be understood that the first information can be associated with multiple types of information, for example, can be associated with one or more of the following: a first geographical location, and a first time domain resource.

[0141] Taking the example that the first information includes multiple candidate beam indication information, the multiple candidate beam indication information can be associated with different geographical locations and / or different time domain resources.

[0142] That is to say, the beam indication information used to send or receive perception signals can be bound to different geographical locations or different time domain resources, that is, different geographical locations are bound to different beams for sending or receiving perception signals, or different time domain resources are bound to different beams for sending or receiving perception signals.

[0143] In a scenario where the first communication device moves, the first communication device may move between different geographical locations (multiple geographical locations), wherein the different geographical locations include a first geographical location, wherein the first geographical location corresponds to a first beam (or first beam indication information).

[0144] In some embodiments, there is an association or correspondence between one of the different geographical locations and the beam (or beam indication information) used to send or receive the perception signal. Thus, when the first communication device moves to a different geographical location, the beam corresponding to the geographical location to which it moves can be used to send or receive the perception signal. In other words, when the first communication device moves to a different geographical location, different beams can be used to send or receive the perception signal. Figure 6 shows an example of using different beams to send or receive the perception signal during movement of the first communication device.

[0145] In some embodiments, each of the different geographical locations corresponds to a beam used to transmit or receive the perception signal. That is, there is a one-to-one correspondence between the geographical location and the beam used to transmit or receive the perception signal. Thus, when the first communication device moves to a different geographical location, it can directly use the unique beam corresponding to the geographical location to transmit or receive the perception signal.

[0146] In some embodiments, one of the different geographical locations corresponds to multiple beams used to send or receive sensing signals. In other words, there is a one-to-many correspondence between geographical locations and beams used to send or receive sensing signals.

[0147] In some embodiments, when a geographical location corresponds to multiple beams for sending or receiving perception signals, the first communication device may also receive activation information, which is used to indicate one of the multiple beams for sending or receiving perception signals corresponding to the geographical location, so that the first communication device sends or receives the perception signal based on the beam corresponding to the activation information.

[0148] In some embodiments, the first communication device may determine a beam for sending or receiving the sensing signal based on the geographical location range it is currently residing in. For example, the first communication device may determine the first beam indication information based on the geographical location range it is currently residing in.

[0149] In some embodiments, the association or correspondence between the geographical location and the beam used to send or receive the sensing signal may be preconfigured, for example, by the network, or by the second communication device, etc.

[0150] The embodiments of the present application do not limit the granularity of dividing the scopes of different geographical locations (or, first geographical locations). Exemplarily, the scopes of different geographical locations can be determined based on one or more of the following granularities: cell, SSB, RAN-based notification area (RNA), tracking area (TA), and tracking area list (TA list). That is to say, the scopes of different geographical locations can be distinguished according to different cells, or can be distinguished according to different SSBs, or can be distinguished according to different RNAs, or can be distinguished according to different TAs or TA lists. Of course, the embodiments of the present application are not limited to this. In some embodiments, the scopes of different geographical locations can also be determined according to a mixture of different regional units. For example, the scopes of different geographical locations can be distinguished according to a mixture of cells and SSBs, or the scopes of different geographical locations can be distinguished according to a mixture of cells, RNAs, and TAs, and so on.

[0151] In some embodiments, the first communications device may determine the beam used to send or receive the perception signal based on one or more of the following: the ID of the cell currently residing or accessed, the RNA ID, the TA ID, the SSB with the highest current wireless signal measurement result, or the SSB selected by the first communications device. For example, the first communications device may determine the beam used to send or receive the perception signal based on the ID of the cell currently residing or accessed. Alternatively, the first communications device may determine the beam used to send or receive the perception signal based on the RNA ID of the cell currently residing or accessed. Alternatively, the first communications device may determine the beam used to send or receive the perception signal based on the ID of the cell currently residing or accessed and the TA ID, and so on.

[0152] In some embodiments, different geographical locations may correspond to different beams for sending or receiving perception signals, which may mean that the TCI states corresponding to different geographical locations are different, for example, the reference signals (such as the identifiers of the reference signals) contained in the TCI states are different.

[0153] In some embodiments, the reference signal included in the TCI state may be sent by a serving cell of the first communications device. In some embodiments, the reference signal included in the TCI state may be sent by another serving cell.

[0154] Example 2:

[0155] In the second embodiment, the first information can be used to indicate the location information of the perception target. There are many ways to implement the first information to indicate the location information of the perception target, and the embodiments of the present application are not limited to this. In some embodiments, the first information can be used to directly indicate the location information of the perception target. For example, the first information may include the location information of the perception target. In some embodiments, the first information can be used to indirectly indicate the location information of the perception target. For example, the first information can use the location information of a communication device near the perception target or the location information of a communication device carried by the perception target to indirectly indicate the location information of the perception target.

[0156] For ease of understanding, two specific implementations of the first information being used to indicate the location information of the perception target are given below.

[0157] Implementation method 1: Directly indicate the location information of the perceived target

[0158] As an implementation manner, the first information may include location information of the perception target, so that the first communication device determines a beam for sending or receiving the perception signal according to the location information of the perception target.

[0159] In some embodiments, the first information including the location information of the perception target may mean that the first information may include the physical location information of the perception target.

[0160] The embodiments of the present application do not limit the method for representing the physical location information of the sensing target. In some embodiments, the physical location information of the sensing target can be represented using absolute coordinates or relative coordinates. In some embodiments, the physical location information of the sensing target can be represented using the latitude and longitude coordinates of the sensing target. In some embodiments, the physical location information of the sensing target can be represented using polar coordinates, etc.

[0161] In some embodiments, the first information including the location information of the sensing target may mean that the first information may include information of the location zone where the sensing target is located. For example, the first information may include the ID (zone ID) of the location zone where the sensing target is located.

[0162] In some embodiments, the location area where the sensing target is located may be predefined, for example, predefined by a protocol.

[0163] The embodiment of the present application does not specifically limit the division method of the location area where the target is located. For example, the location area where the target is located can be divided according to cells. Alternatively, the location area where the target is located can be divided according to tracking areas (TAs). Alternatively, the location area where the target is located can be divided according to SSBs, etc.

[0164] In this way, the first communication device can determine an appropriate beam for sending or receiving the perception signal according to its own position information and the position information of the perception target.

[0165] The embodiment of the present application does not specifically limit the manner in which the first communication device obtains its own location information. For example, the first communication device may obtain its own location information through a global navigation satellite system (GNSS). Alternatively, the first communication device may obtain its own location information based on certain positioning methods, such as a positioning method based on a radio access technology (RAT). The embodiment of the present application does not limit the positioning method based on RAT, and may include, for example, a positioning method based on a downlink arrival time difference, a positioning method based on an uplink arrival time difference, a positioning method based on a multi-cell round trip time (RTT), and the like.

[0166] Implementation method 2: Indirect indication of the location information of the perceived target

[0167] As an implementation, the first information may include relevant information of a third communication device, and the relevant information of the third communication device is used by the first communication device to determine the location information of the perception target. In other words, the relevant information of the third communication device can be used by the first communication device to determine the beam used to send or receive the perception signal. In some embodiments, the third communication device may also be referred to as a third-party device, a label device, etc. For example, the third communication device may be a third-party UE, a label UE, etc.

[0168] It should be noted that the third communication device is not the transmitter or receiver of the perception signal. The third communication device is similar to a label in the perception process, which can simplify certain processes.

[0169] In some embodiments, the third communication device may be a communication device near the sensing target. For example, the third communication device may be a communication device whose distance from the sensing target is less than a certain threshold, such as less than 500 meters, less than 300 meters, etc.

[0170] In some embodiments, the third communication device may be a communication device carried by the sensing target. For example, when the sensing target is a car, the third communication device may be an onboard terminal in the car.

[0171] The embodiments of the present application do not limit the specific content of the relevant information of the third communication device, as long as it can be used by the first communication device to determine the location information of the perceived target. For example, the relevant information of the third communication device may include one or more of the following: beam indication information corresponding to the communication link between the third communication device and the first communication device, and identification information of the third communication device.

[0172] As an example, the relevant information of the third communication device may include beam indication information corresponding to the communication link between the third communication device and the first communication device. Taking the example that the third communication device and the first communication device are both terminal devices, the relevant information of the third communication device may include, for example, beam indication information (such as TCI status information) on the sidelink between the two terminal devices. In this way, the first communication device can use the beam corresponding to the beam indication information of the communication link between the third communication device and the first communication device to send or receive a perception signal, so as to align with the perception target.

[0173] As another example, the relevant information of the third communication device may include ID information of the third communication device. The first communication device may discover the third communication device or establish a communication link with the third communication device based on the ID information of the third communication device, and then independently estimate the beam used for sending or receiving the perception signal based on the measurement. Taking the example where both the third communication device and the first communication device are terminal devices, the first communication device may, based on the ID information of the third communication device, perform sidelink discovery or establish a sidelink (e.g., a unicast sidelink) with the third communication device, and then independently estimate the beam used for sending or receiving the perception signal based on the measurement.

[0174] As another example, the relevant information of the third communication device may include beam indication information corresponding to the communication link between the third communication device and the first communication device, and ID information of the third communication device.

[0175] In some embodiments, the relevant information of the third communication device may be configured by the network side to the first communication device.

[0176] In some embodiments, the relevant information of the third communication device may be configured by the second communication device to the first communication device.

[0177] The first communication device uses the relevant information of the third communication device to determine the location information of the perception target, which helps the first communication device to better align with the perception target so that the perception signal can better rush towards the perception target.
