[0059] It should be understood that in the embodiments of the present application, a device having a communication function in a network / system may be referred to as a communication device. Taking the communication system shown in Figure 1 as an example, the communication device may include a network device and a terminal device having a communication function. The network device and the terminal device may be specific devices in the embodiments of the present application and will not be described in detail here. The communication device may also include other devices in the communication system, such as a network controller, a mobility management entity, and other network entities, which are not limited in the embodiments of the present application.
[0060] To facilitate understanding of the embodiments of the present application, the following briefly describes the basic processes and basic concepts involved in the embodiments of the present application. It should be understood that the basic processes and basic concepts introduced below do not limit the embodiments of the present application.
[0061] The 5G network system architecture is shown in Figure 2, which includes: NSSF (Network Slice Selection Function) is mainly used to manage network slice related information, such as selecting network slices for terminal devices; AUSF (Authentication Server Function) is used to complete the identity authentication function of user access; UDM (Unified Data Management) is used to manage and store contract data and authentication data; AMF (Access and Mobility Management Function) is used to complete mobility management, security anchor and security context management, etc. In addition to managing the mobility of UE, AMF is also responsible for forwarding session management related messages between UE and SMF; SMF (Session Management Function) is used to complete session management, UE IP address allocation and management, etc.; PCF (Policy Control Function) is responsible for formulating policies related to UE mobility management, session management, billing, etc.; AF (Application Function) is used for external application servers; UPF (User Plane Function) is used to manage and store user data and authentication data; Function) is used for complex user plane processing, such as forwarding traffic between the wireless access network and the Internet, reporting traffic usage, and implementing QoS (Quality of Service) policies. DN (Data Network) refers to the 5GC external data network (such as the Internet).
[0062] In addition, data is transmitted between various nodes in the 5G Core Network (5G Core Network), between user equipment (UE) and 5G Core Network nodes, between the UE and the Radio Access Network (RAN), and between the RAN and 5G Core Network nodes through corresponding interfaces. For example, as shown in Figure 2, data is transmitted between the AMF and the NSSF in the 5G Core Network (5G Core Network) via interface N22; data is transmitted between the AMF and the SMF via interface N11; data is transmitted between the AMF and the AUSF via interface N12; and data is transmitted between the AMF and the UDM via interface N8. Data is transmitted between the SMF and the UPF via interface N4. The UPF transmits data to the external data network via interface N6 and to the AN via interface N3. The UE connects to the AN via the Uu interface for access layer communication, exchanging access layer messages and wireless data transmission. The UE connects to the AMF via the N1 interface for non-access layer (NAS) communication, exchanging NAS messages. Data is transmitted between the RAN and the AMF via interface N2, and between the RAN and the UPF via interface N3. It should be understood that the above only describes the interfaces between some nodes, and other interfaces between other 5GC nodes in Figure 2 are not described one by one.
[0063] Cellular networks, including 5G networks, are used solely for communication. However, the radio electromagnetic wave signals used by cellular networks can be used not only for wireless data transmission and communication but also for environmental perception, such as user motion or gesture recognition, respiratory monitoring, terminal movement speed measurement, environmental imaging, and weather monitoring. Therefore, in the future, cellular networks may be considered not only for communication and data transmission, but also for acquiring sensory information. This potential scenario is referred to as synaesthesia integration or communication-perception integration.
[0064] The main wireless sensing scenarios for the aforementioned synaesthesia integration are as follows:
[0065] 1) Base station echo sensing link: The base station sends a sensing signal and receives an echo signal;
[0066] 2) Inter-base station sensing link: Base station B receives the sensing signal sent by base station A;
[0067] 3) Air interface uplink sensing link: The base station receives the sensing signal sent by the terminal;
[0068] 4) Air interface downlink sensing link: The terminal receives the sensing signal sent by the base station;
[0069] 5) Terminal echo sensing link: The terminal sends a sensing signal and receives an echo signal;
[0070] 6) Inter-terminal perception link: Terminal B receives the perception signal sent by terminal A.
[0071] In the early stages of B5G communication and perception integration, consideration should be given to reusing existing air interface signals to perform perception behaviors as much as possible without introducing excessive air interface enhancements.
[0072] Currently, there is a discussion on supporting sensing capabilities in B5G networks. This is done by adding sensing control network elements (Sensing Functions) and corresponding processes to support sensing functions in 3GPP networks. Figure 3 shows a possible flow chart for controlling access network devices or UEs to perform UE-level sensing operations, specifically including:
[0073] S301. AF sends a perception request to the perception control network element of the core network; for example, the application function (AF) sends a perception request for the target UE / object to the core network of the 3GPP network; wherein the perception request includes UE information and perception type.
[0074] S302. The perception control network element (or AMF) sends a perception instruction to the mobility management network element. The perception instruction includes UE information and perception type.
[0075] S303: The mobility management network element determines a potential sensing access network device or a potential sensing target terminal.
[0076] If the mobility management network element determines a potential perception access network device, S304 and S305 are executed; if the mobility management network element determines a potential perception target terminal, S306 and S307 are executed.
[0077] S304-S305: The mobility management network element sends a perception instruction to the potential perception access network device, and the potential perception access network device performs relevant processing of communication perception.
[0078] S306-S307: The mobility management network element sends a sensing instruction to the potential sensing target terminal, which performs communication sensing-related processing. The sensing instruction is used to trigger the potential sensing target terminal or the potential sensing access network device to perform sensing-related wireless measurements, start measuring sensing information, and generate sensing results.
[0079] Principle of radar lock determination: Radar lock determination means that, for a period of time, the enemy radar's transmit beam can accurately determine the target's position, range, and speed, allowing it to track us. Generally speaking, active radars transmit distinct signals in search and lock modes, such as frequency (low-frequency signals have a wider coverage area and are used to expand the search range; high-frequency signals have a wider spectrum and provide higher detection accuracy). Alternatively, if the signal received from our RF link increases significantly in power, it can be determined that we have been locked onto the enemy radar.
[0080] RRC (Radio Resource Control)_Inactive or RRC_idle terminals: In these states, the network is unaware of the terminal's location. Therefore, while the network is providing communication awareness services to a particular terminal, other terminals traveling with it within a certain period of time may also be illuminated by the awareness beam (with received signal measurements exceeding a certain threshold). The network can then analyze the tracking reflection results to track the terminal. In this case, the terminal may believe its privacy has been violated.
[0081] It should be understood that the terms "system" and "network" are often used interchangeably herein. The term "and / or" is simply a description of an association between related objects, indicating that three possible relationships exist. For example, "A and / or B" can represent: A exists alone, A and B exist simultaneously, or B exists alone. Furthermore, the character " / " generally indicates that the related objects are in an "or" relationship.
[0082] It should be understood that the "indication" mentioned in the embodiments of this application can be a direct indication, an indirect indication, or an indication of an association. For example, "A indicates B" can mean that A directly indicates B, for example, B can be obtained through A; it can also mean that A indirectly indicates B, for example, A indicates C, and B can be obtained through C; it can also mean that there is an association between A and B.
[0083] In the description of the embodiments of the present application, the term "corresponding" may indicate a direct or indirect correspondence between the two, or an association relationship between the two, or a relationship between indication and being indicated, configuration and being configured, etc.
[0084] To facilitate understanding of the technical solutions of the embodiments of the present application, the relevant technologies of the embodiments of the present application are described below. The following relevant technologies can be arbitrarily combined with the technical solutions of the embodiments of the present application as optional solutions, and they all fall within the protection scope of the embodiments of the present application.
[0085] Figure 4 is a schematic flow chart of a communication method according to an embodiment of the present application. The method includes at least part of the following contents.
[0086] S410. The first device sends request information; the request information is used to request processing of a perception signal.
[0087] Here, the first device may be a terminal device.
[0088] In some possible implementations, the method may further include:
[0089] The first device sends the request information when the perception signal meets a preset condition;
[0090] The preset conditions include at least one of the following:
[0091] The measurement result of the sensing signal is greater than a first threshold;
[0092] The duration of the perception signal is greater than a second threshold.
[0093] Specifically, when the perception signal satisfies a preset condition, the first device sending the request information may include:
[0094] The first device determines whether a perception signal is detected; if the first device detects the perception signal, determines whether the perception signal meets the preset condition; if the perception signal meets the preset condition, sends the request information.
[0095] In some embodiments, the perception signal may be sent by a second device, which may be a terminal device or an access network device.
[0096] Optionally, the perception signal is transmitted on a first time-frequency resource; the first time-frequency resource is different from a second time-frequency resource, and the second time-frequency resource is used to transmit signals other than the perception signal. Accordingly, the manner in which the first device determines whether the perception signal is detected may include: determining that the perception signal is detected when the first device detects a wireless signal on the first time-frequency resource.
[0097] The aforementioned first time-frequency resource is different from the second time-frequency resource, which may mean that the frequency domain range and / or time domain range of the first time-frequency resource is different from that of the second time-frequency resource.
[0098] The signal other than the perception signal may refer to a signal used for wireless data communication other than the perception signal as specified in the relevant protocol. For example, when the second device is an access network device and the first device is a terminal device, the signal other than the perception signal may be a downlink signal used for wireless data communication other than the perception signal as specified in the relevant protocol. For example, when the second device is a terminal device and the first device is a terminal device, the signal other than the perception signal may be a sidelink signal used for wireless data communication other than the perception signal as specified in the relevant protocol.
[0099] Optionally, the perception signal carries first information, where the first information is used to determine that the signal type is a wireless signal for perception. Accordingly, the manner in which the first device determines whether the perception signal is detected may include: upon receiving a wireless signal that carries the first information, the first device determines that the perception signal is detected.
[0100] Specifically, the first information may be: specified content of a specified bit in the occupancy perception signal. The specified bit may be N pre-specified bits in the perception signal; for example, the first N bits, where N is an integer greater than or equal to 1. The specified content may be pre-configured based on actual circumstances. For example, if the specified bit is the first bit of the perception signal, the specified content refers to the value of the first bit being a first value (the first value may be 1 or 0).
[0101] Optionally, the perception signal carries the first information and is transmitted on the first time-frequency resource. Accordingly, the manner in which the first device determines whether the perception signal is detected may include: when the first device detects a wireless signal on the first time-frequency resource, determining whether the wireless signal detected on the first time-frequency resource carries the first information; and determining that the perception signal is detected if it is determined that the wireless signal carries the first information.
[0102] In some embodiments, when the first device detects the perception signal, determining whether the perception signal meets the preset condition may include: after the first device determines that the perception signal is detected, determining whether the measurement result of the perception signal is greater than the first threshold; when the measurement result of the perception signal is greater than the first threshold, determining that the perception signal meets the preset condition.
[0103] The first threshold is preset or configured by a network device. The aforementioned network device may refer to an access network device of a cell where the first device is located, that is, a serving base station of the cell where the first device is located.

[0107] The second threshold is preset or configured by a network device. The aforementioned network device may refer to an access network device of the cell where the first device is located, that is, a serving base station of the cell where the first device is located.
[0108] In which, when the second threshold is configured by the network device, the second threshold is carried by one of the following: a system broadcast message, a second RRC signaling, a second DCI, and a second MAC CE.
[0109] The second RRC signaling may be the same as or different from the first RRC signaling. The second MAC CE may be the same as or different from the first MAC CE. The second DCI may be the same as or different from the first DCI.
[0110] In some embodiments, when the first device detects the perception signal, determining whether the perception signal meets the preset condition may include: after the first device determines that the perception signal is detected, determining whether the duration of the perception signal is greater than the second threshold, and determining whether the measurement result of the perception signal remains greater than the first threshold during the duration; if it is determined that the duration of the perception signal exceeds the second threshold, and the measurement result within its duration remains greater than the first threshold, then determining that the perception signal meets the preset condition.
[0111] Optionally, the perception signal carries a related identifier of a second device; wherein the second device is a device that sends the perception signal. The related identifier of the second device can specifically be an ID (identity) of the second device. Exemplarily, the ID of the second device can be represented by any one of a temporary mobile subscriber identity (TMSI), an international mobile subscriber identity (IMSI), an I-RNTI (Inactive Radio Network Temporary Identifier), and the like.
[0112] In some possible implementations, the request information is used to request to stop sending the perception signal; or, the request information is used to request to reduce the beamwidth of the perception signal.
[0113] The request information may be carried or represented by one of the following: information 1 (msg1) in the 4-step random access process; information 3 (msg3) in the 4-step random access process; information A (msgA) in the 2-step random access process; the third MAC CE; or the third RRC signaling.
[0114] When the request information is represented by msg1 in the four-step random access process, the msg1 may occupy a third time-frequency resource; and / or the request information includes a designated sequence. The third time-frequency resource is configured by the network device; and the designated sequence is different from the preamble sequence.
[0115] Optionally, the third time-frequency resource refers to a time-frequency resource dedicated to transmitting msg1 representing the request information. The third time-frequency resource is different from the time-frequency resource used to transmit the preamble sequence specified in the relevant protocol.
[0116] The aforementioned network device may refer to an access network device of the cell where the first device is located, that is, a serving base station of the cell where the first device is located. Specifically, the configuration information of the third time-frequency resource may be carried by any one of the following: a system broadcast message, a fifth RRC signaling, a third DCI (Downlink Control Information), a fifth MAC CE, etc.
[0117] The fifth RRC signaling is the same as or different from the first RRC signaling, or the fifth RRC signaling is the same as or different from the second RRC signaling. The fifth MAC CE is the same as or different from the first MAC CE, or the fifth MAC CE is the same as or different from the second MAC CE. The third DCI is the same as or different from the first DCI, or the third DCI is the same as or different from the second DCI.
[0118] Optionally, when the request information is represented by the msg1, the request information includes a specified sequence, and the specified sequence is different from the preamble sequence.
[0119] Specifically, the designated sequence is different from any preamble sequence specified in the relevant protocol. The various preamble sequences specified in the relevant protocol are not described here. In this case, the time-frequency resources occupied by the msg1 are not limited.
[0120] Optionally, when the request information is represented by the msg1, the request information includes a specified sequence, and msg1 occupies the third time-frequency resource.

[0122] In the case where the request information is carried by msgA in the 2-step random access process, the request information includes a specified sequence, or the request information can be a specified cause value. The specified sequence and the specified cause value are the same as those described in the previous embodiment and are not repeated here.
[0123] The aforementioned third MAC CE may be an uplink MAC CE; the aforementioned third RRC signaling may be an uplink RRC signaling.
[0124] In some embodiments, the first device may send the request information via a sidelink. In this embodiment, the third MAC CE is a sidelink MAC CE; or the third RRC signaling is a sidelink RRC signaling.
[0125] In some embodiments, the request information may also carry a related identifier of the second device. The related identifier of the second device is the same as that in the above embodiment and will not be described repeatedly.
[0126] Specifically, if the aforementioned perception signal carries the relevant identifier of the second device, the request message may carry the relevant identifier of the second device. That is, when the first device detects the perception signal, it can parse the perception signal to obtain the relevant identifier of the second device. When the first device sends the request message, it adds the relevant identifier of the second device to the request message and sends it. By carrying the relevant identifier of the second device in the request message, the receiving device can determine to which device the instruction information for processing the perception signal should be sent.
[0127] In some possible implementations, the method further includes one of the following: the first device starts a timer when sending the request information; the first device starts a timer when the perception signal meets a preset condition.
[0128] That is, the first device may control the start of the timer at the moment of sending the request information after determining that it is in the sensing signal tracking state. Alternatively, the first device may control the start of the timer at the moment when the sensing signal meets the preset conditions, and simultaneously generate and send the aforementioned request information. Here, when the first device determines that the sensing signal meets the preset conditions, it may determine that it is being tracked by the sensing signal, and may further control the start of the timer and generate and send the aforementioned request information.
[0129] Correspondingly, the method also includes one of the following: the first device does not detect the perception signal when the timer has not reached the timing duration; the first device does not send new request information when the timer has not reached the timing duration.
[0130] The timing duration is preset or configured by a network device. The aforementioned network device may refer to an access network device of the cell where the first device is located, that is, a serving base station of the cell where the first device is located.
[0131] When the timing duration is configured by the network device, the timing duration is carried by one of the following: a system broadcast message, a fourth RRC signaling, a fourth DCI, or a fourth MAC CE. Here, the fourth RRC signaling may be the same as or different from the first RRC signaling or the second RRC signaling. The fourth MAC CE may be the same as or different from the first MAC CE or the second MAC CE. The fourth DCI may be the same as or different from the first DCI or the second DCI.
[0132] The length of the aforementioned timing duration can be configured according to actual conditions, for example, it can be 5 minutes, 10 minutes, or longer or shorter, and the examples are not exhaustive here.
[0133] In one case, the first device does not detect the perception signal when the timer does not reach the timing duration.
[0134] That is, from the time the first device starts the timer until the timer starts and the timer duration reaches the set duration, the first device will no longer detect the sensing signal; and because the first device no longer detects the sensing signal, the first device will no longer send new request information. This can prevent the first device from frequently detecting the sensing signal and frequently reporting request information, thereby reducing the occupation of processing resources and reducing the occupation of air interface resources.
[0135] In another case, the first device does not send new request information when the timer does not reach the timing duration.
[0136] That is, from the time the first device starts the timer until the timer starts and the timer reaches the set duration, the first device can continue to detect the perception signal, but will not send new request information. This can avoid the first device from frequently reporting request information, thereby reducing the occupation of air interface resources.
[0137] By adopting the above solution, the first device can send request information for requesting processing of the perception signal, so that the network side can perform corresponding processing on the perception signal, which can avoid the privacy leakage of the first device and ensure the information security of the first device.
[0138] Furthermore, when the first device detects a perception signal and determines that the perception signal meets a preset condition, it can request to process the perception signal. In this way, the first device can avoid being aware of relevant information through the perception signal, thereby avoiding privacy leakage of the first device and ensuring the information security of the first device.
[0139] Figure 5 is a schematic flow chart of a communication method according to an embodiment of the present application. The method includes at least part of the following contents.
[0140] S510: The second device processes the perception signal while sending the perception signal.
[0141] The processing of the perception signal may include one of the following: stopping sending the perception signal; continuing sending the perception signal; and adjusting the beam width of the perception signal. The adjusting the beam width of the perception signal may specifically include reducing the beam width of the perception signal.
[0142] In some possible implementations, the processing the perception signal includes:
[0143] The second device receives the request information, where the request information is used to request processing of the perception signal;
[0144] The second device processes the perception signal based on the request information.
[0145] The second device receiving the request information may include: the second device receiving the request information sent by the first device.
[0146] In this embodiment, the second device can directly communicate with the first device. The second device can be a terminal device or an access network device.
[0147] In the case where the second device is a terminal device, the second device and the aforementioned first device may be two terminals performing sidelink communication, and the second device also sends a perception signal to the first device at the same time.
[0148] In the case where the second device is an access network device, the access network device may be an access network device of a network where the first device is located. In one example, the second device not only sends the sensing signal but also serves as a serving base station for the first device.
[0149] Optionally, the request information is used to request to stop sending the perception signal. The second device processes the perception signal based on the request information, including: the second device stops sending the perception signal based on the request information. The stopping sending the perception signal refers to stopping sending the perception signal to the first device.
[0150] Optionally, the request information is used to request reducing the beamwidth of the perception signal. The second device processes the perception signal based on the request information, including: the second device reduces the beamwidth of the perception signal based on the request information, and sends the perception signal with the reduced beamwidth.
[0151] Specifically, the sending of the perception signal may include: the second device sending the perception signal to the first device with an initial beam width.
[0152] The second device reducing the beamwidth of the perception signal based on the request information and sending the perception signal with the reduced beamwidth may include: the second device reducing the beamwidth of the perception signal from the initial beamwidth to a target beamwidth based on the request information, and sending the perception signal with the reduced beamwidth to the first device; wherein the target beamwidth is smaller than the initial beamwidth. The target beamwidth may be determined by the second device itself, for example, half or one-third of the initial beamwidth, etc., without exhaustive enumeration. As long as the target beamwidth is smaller than the initial beamwidth, it is within the scope of protection of this embodiment.
[0153] Alternatively, the request information may include a target beam width; the target beam width is smaller than the initial beam width. Accordingly, the second device reducing the beam width of the perception signal based on the request information and sending the perception signal with the reduced beam width may include: the second device parsing the request information to obtain the target beam width; the second device reducing the beam width of the perception signal from the initial beam width to the target beam width, and sending the perception signal with the reduced beam width to the first device.
[0154] In some possible implementations, the processing the perception signal includes:
[0155] The second device receives indication information; wherein the indication information is used to indicate processing of the perception signal;
[0156] The second device processes the perception signal based on the indication information.
[0157] In this embodiment, the second device does not communicate directly with the first device. The second device may be a terminal device or an access network device. If the second device is an access network device, it is not an access network device of the network where the first device resides, that is, it is not a serving base station for the first device. If the second device is a terminal device, it does not perform sidelink communication with the first device.
[0158] More specifically, sending the perception signal may include: the second device sending the perception signal to the first device with an initial beam width. The second device receiving the indication information may include: the second device receiving the indication information sent by the core network device.
[0159] The core network device may be a perception control network element in the core network. It should be understood that this is merely an exemplary description, and the core network device may also be other network elements in the core network, which are not exhaustive here.
[0160] The indication information may include one of the following: information for indicating to stop the perception service; information for indicating to continue the perception service; and information for indicating to reduce the beam width of the perception signal.
[0161] In the case of different indication information, the second device performs different operations on the sensing signal, which are described below respectively:
[0162] In one scenario, the indication information includes information for instructing to stop the perception service. The second device processes the perception signal based on the indication information, including: the second device stops sending the perception signal based on the information for instructing to stop the perception service. The stopping of sending the perception signal may include stopping sending the perception signal to the first device.
[0163] In another embodiment, the indication information includes information for indicating that the service should continue to be perceived. The second device processes the perception signal based on the indication information, including one of the following:
[0164] The second device continues to send the perception signal based on the information for instructing to continue the perception service;
[0165] The second device reduces the beamwidth of the perception signal based on the information for instructing to continue the perception service, and sends the perception signal with the reduced beamwidth.
[0166] The aforementioned continuing to send the perception signal may refer to: the second device continuing to send the perception signal to the first device with the initial beam width.
[0167] Reducing the beamwidth of the perception signal and transmitting the perception signal with the reduced beamwidth may include: reducing the beamwidth of the perception signal from an initial beamwidth to a target beamwidth; and transmitting the perception signal to the first device with the target beamwidth. The target beamwidth is smaller than the initial beamwidth.
[0168] Here, the second device may determine which of the above-mentioned processes to perform based on a preset processing strategy. The preset processing strategy may be configured according to actual conditions, for example, the preset processing strategy may be: if information indicating that the service is to be continued is received, then the sensing signal is continued to be sent; or if information indicating that the service is to be continued is received, then the beamwidth of the sensing signal is reduced.
[0169] In yet another embodiment, the indication information includes information for indicating reduction of a beamwidth of the perception signal. The second device processing the perception signal based on the indication information includes: the second device reducing the beamwidth of the perception signal based on the information for indicating reduction of the beamwidth of the perception signal, and transmitting the perception signal with the reduced beamwidth.
[0170] The second device reducing the beamwidth of the perception signal based on the information indicating the reduction of the beamwidth of the perception signal and transmitting the perception signal with the reduced beamwidth may include: the second device reducing the beamwidth of the perception signal from the initial beamwidth to a target beamwidth based on the information indicating the reduction of the beamwidth of the perception signal, and transmitting the perception signal with the reduced beamwidth to the first device. The perception signal with the reduced beamwidth is a perception signal with a target beamwidth. The target beamwidth is smaller than the initial beamwidth.
[0171] Alternatively, the information for indicating the reduction of the beamwidth of the perception signal may include a target beamwidth; the target beamwidth is smaller than the initial beamwidth. Accordingly, the second device reducing the beamwidth of the perception signal based on the information for indicating the reduction of the beamwidth of the perception signal and sending the perception signal with the reduced beamwidth may include: the second device parsing the information for indicating the reduction of the beamwidth of the perception signal to obtain the target beamwidth; the second device reducing the beamwidth of the perception signal from the initial beamwidth to the target beamwidth, and sending the perception signal with the reduced beamwidth to the first device.
[0172] In some possible implementations, the processing the perception signal includes:
[0173] The second device receives the request information, where the request information is used to request processing of the perception signal;
[0174] The second device sends the request information;
[0175] The second device receives indication information; wherein the indication information is used to indicate processing of the perception signal;
[0176] The second device processes the perception signal based on the indication information.
[0177] In this embodiment, the second device can communicate directly with the first device. The second device can be a terminal device or an access network device. If the second device is an access network device, it can be an access network device of the network where the first device is located. If the second device is a terminal device, the second device and the first device can be two terminals performing sidelink communication, and the second device can also send a perception signal to the first device.
[0178] The difference from the above embodiment is that, in this embodiment, although the second device can communicate with the first device, the second device does not make a decision, but instead sends a request message and then processes the perception signal based on the received indication information.
[0179] Specifically, sending the perception signal may include: the second device sending the perception signal to the first device.
[0180] The second device sending the request information may include: the second device sending the request information to the core network device.
[0181] The second device receiving the indication information may include: the second device receiving the indication information sent by the core network device.
[0182] The content that the indication information may include is the same as that in the above embodiment and will not be described in detail. The second device processes the perception signal based on the indication information in the same way as in the above embodiment and will not be described in detail here.
[0183] In one embodiment, the perception signal is transmitted on a first time-frequency resource; the first time-frequency resource is different from a second time-frequency resource, and the second time-frequency resource is used to transmit signals other than the perception signal. The description of the first time-frequency resource and the second time-frequency resource is the same as that in the aforementioned embodiment of the communication method for the first device and is not repeated here.
[0184] In one embodiment, the sensing signal carries first information, wherein the first information is used to determine that the signal type is a wireless signal for sensing. The description of the first information is the same as the relevant description in the aforementioned embodiment of the communication method of the first device, and is not repeated here.
[0185] In one embodiment, the sensing signal also carries a related identifier of the second device. The description of the related identifier of the second device is the same as that in the aforementioned embodiment of the communication method for the first device, and is not repeated here.
[0186] In some possible implementations, the request information may be carried or represented by one of the following: information 1 (msg1) in the 4-step random access process; information 3 (msg3) in the 4-step random access process; information A (msgA) in the 2-step random access process.
[0187] When the request information is represented by the msg1, the msg1 occupies a third time-frequency resource, and / or the request information includes a specified sequence; wherein the third time-frequency resource is configured by the network device; the specified sequence is different from the preamble sequence.
[0188] Here, the network device may refer to an access network device of the network where the first device is located.
[0189] In one example, the second device may be an access network device of the network where the first device is located. In this scenario, the network device and the second device are the same device. In another example, the second device may be a terminal device. In this case, the second device may be a receiving network device (i.e., an access network device of the network where the first device is located) that sends the configuration information of the third time-frequency resource. For example, if the second device is not within the coverage of the aforementioned network device (i.e., the access network device of the network where the first device is located), the second device may be the access network device of its own network that forwards the configuration information of the third time-frequency resource of the network device. If the second device is within the coverage of the aforementioned network device, the second device may directly receive the configuration information of the third time-frequency resource sent by the network device. The method for sending the configuration information of the third time-frequency resource has been described in the aforementioned embodiment of the communication method for the first device and will not be repeated here.
[0190] The description of the third time-frequency resource and the designated sequence is the same as the related description in the aforementioned communication method embodiment of the first device and is not repeated here.
[0191] When the request information is carried by msg3 in the 4-step random access process, the request information may be a specified cause value; the specified cause value may be used to indicate a request to process the perception signal. The specified cause value is different from the cause value specified in the relevant protocol.
[0192] When the request information is carried by msgA in the two-step random access process, the request information includes a specified sequence, or the request information can be a specified cause value. The specified sequence and the specified cause value are the same as those described in the aforementioned embodiment of the communication method for the first device, and are not repeated here.
[0193] In some possible implementations, the request information may be carried by one of the following: a third MAC CE, a third RRC signaling.
[0194] In some embodiments, the second device is a terminal device, and the second device and the first device are two terminals performing sidelink communication. In this case, the third MAC CE is a sidelink MAC CE; or the third RRC signaling is a sidelink RRC signaling.
[0195] In some embodiments, the request information may also carry the relevant identifier of the second device. Specifically, if the sensing signal carries the relevant identifier of the second device, the request information may carry the relevant identifier of the second device.
[0196] By adopting the above solution, the second device can process the perception signal while sending the perception signal, thereby avoiding privacy leakage of the first device and ensuring the information security of the first device.
[0197] Figure 6 is a schematic flow chart of a communication method according to an embodiment of the present application. The method includes at least part of the following contents.
[0198] S610. The core network device receives request information, where the request information is used to request processing of the perception signal.
[0199] S620. The core network device sends indication information; the indication information is used to indicate processing of the perception signal.
[0200] Here, the core network device may be any network element of the core network. In a preferred example, the core network device may specifically be: a perception control network element in the core network.
[0201] In some implementations, the core network device receiving the request information may include: the core network device receiving the request information sent by the network device. The core network device sending the indication information may include: the core network sending the indication information to the second device.
[0202] The network device is an access network device of the network where the first device in the aforementioned embodiment is located. Accordingly, the core network device receives the request information sent by the network device, specifically: the core network device receives the request information sent by the first device through the network device.
[0203] In one example, the core network device may be a perception control network element, which may receive the request information sent by the first device from the network device via a mobility management network element. The mobility management network element may be an AMF in the core network, or other network elements in the core network, which are not exhaustive.
[0204] The second device is a device that sends a perception signal. The second device is different from the access network device of the network where the first device is located; the second device can be a terminal device, or can be an access network device other than the access network device of the network where the first device is located.
[0205] In some implementations, the core network device receiving the request information may include: the core network receiving the request information sent by a second device, wherein the second device is a device that sends a perception signal. The core network device sending the indication information may include: the core network sending the indication information to the second device.
[0206] The second device is an access network device of the network where the first device is located, and sends a perception signal to the first device.
[0207] In some implementations, the request information is used to request to stop sending the perception signal; or, the request information is used to request to reduce the beamwidth of the perception signal.
[0208] The request message also carries a related identifier of a second device; the second device is the device that sends the perception signal. The core network device can determine the second device to be controlled or instructed to process the perception signal based on the related identifier of the second device carried in the request message.
[0209] The instruction information includes one of the following:
[0210] Information for instructing to stop the perception service, where the information for instructing to stop the perception service is used to determine to stop sending the perception signal;
[0211] Information for instructing to continue the sensing service, where the information for instructing to continue the sensing service is used to determine to continue sending the sensing signal, or to determine to reduce the beamwidth of the sensing signal;
[0212] The information for instructing to reduce the beamwidth of the perception signal, and the information for instructing to continue the perception service is used to determine to reduce the beamwidth of the perception signal.
[0213] After the core network device receives the request information and before sending the instruction information, the process may further include: the core network device makes a decision based on the request information and generates the aforementioned instruction information. Specific descriptions are as follows:
[0214] In one example, the request information is used to request to stop sending the perception signal. Accordingly, the core network device makes a decision based on the request information and generates the aforementioned indication information, which may include: the core network device directly generates information for indicating to stop the perception service based on the request information.
[0215] In another example, the request information is used to request that the second device stop sending the perception signal. Accordingly, the core network device makes a decision based on the request information to generate the aforementioned indication information, which may include: if the core network device determines, based on the request information, that the second device cannot stop sending the perception signal, then generating information indicating that the perception service should continue.
[0216] In this example, the core network device can determine whether the second device can stop the perception service based on the relevant information of the second device. For example, if the second device's perception service level is high or the perception service is an emergency service, the core network device can determine that the second device cannot stop the perception service. It should be understood that this is merely an example. In actual processing, the core network device can determine whether the second device can stop the perception service based on other relevant information of the second device and / or other information such as the current network status, but this is not an exhaustive list.
[0217] In another example, the request information is used to request to stop sending the perception signal. Accordingly, the core network device makes a decision based on the request information to generate the aforementioned indication information, which may include: if the core network device determines, based on the request information, that the second device does not need to stop sending the perception signal but can reduce the beamwidth of the perception signal, then information for instructing to reduce the beamwidth of the perception signal may be generated.
[0218] In this example, the core network device can determine whether the second device can stop the sensing service or whether the beamwidth of the sensing signal can be reduced based on the relevant information of the second device. For example, if the level of the sensing service of the second device is high but not the highest, the core network device can determine that the second device cannot stop the sensing service, but can reduce the beamwidth of the sensing signal. It should be understood that this is merely an example. In actual processing, the core network device can make a decision based on other relevant information of the second device and / or other information such as the current network status, but this is not an exhaustive list.
[0219] In another example, the request information is used to request reduction of the beamwidth of the perception signal. Accordingly, the core network device makes a decision based on the request information and generates the aforementioned indication information, which may include: if the core network device determines, based on the request information, that the second device does not need to reduce the beamwidth of the perception signal, then generating information for instructing to continue the perception service; or if the core network device determines, based on the request information, that the second device can reduce the beamwidth of the perception signal, then generating information for instructing to reduce the beamwidth of the perception signal.
[0220] In this example, the core network device can determine whether the second device needs to reduce the beamwidth of the perception signal based on the relevant information of the second device. For example, if the second device's perception service level is high or the perception service is an emergency service, the core network device can determine that the second device does not need to reduce the beamwidth of the perception signal; otherwise, the core network device determines that the second device can reduce the beamwidth of the perception signal. It should be understood that this is merely an example. In actual processing, the core network device can make a decision based on other relevant information of the second device and / or other information such as the current network status, but this is not an exhaustive list.
[0221] By adopting the above solution, after receiving the request information, the core network device sends an instruction information, which controls the operation of the sensing signal. In this way, the sensing signal can be processed according to the request, thereby preventing the privacy of the sensing device from being leaked and ensuring the information security of the sensing device.
[0222] The communication method performed by the aforementioned first device and the second device is exemplified. Taking the first device as a UE, the second device as a base station, and the second device as a serving base station of the first device as an example, the description is made in conjunction with FIG7 , which may specifically include:
[0223] S710. The base station sends a perception signal to the UE.
[0224] It should be noted that before executing S710, the base station may also receive a sensing instruction, which may include UE information and sensing type, etc. The sensing instruction may be sent by a core network device, for example, see the detailed description of S301 to S305 above, which will not be repeated here.
[0225] S720. The UE sends a request message to the base station; the request message is used to request processing of the perception signal.
[0226] The determination method for the UE to send the request information and the specific description of the request information are the same as the relevant description of any one of the communication methods of the first device and the second device mentioned above, and will not be repeated here for the sake of brevity.
[0227] S730. The base station receives the request information sent by the UE, and processes the perception signal based on the request information.
[0228] Here, the description of the possible contents of the request information and the processing of the perception signal based on the contents of the request information is the same as that in the above embodiment, and thus will not be repeated.
[0229] The communication method performed by the aforementioned first device, second device, and core network device is exemplified. Taking the first device as a UE, the serving base station of the first device as base station A, the second device as base station B, and the core network device as a perception control network element as an example, the description is given in conjunction with Figure 8, which may specifically include:
[0230] S810. Base station B sends a perception signal to UE.
[0231] S820. The UE sends a request message to base station A; the request message is used to request processing of the perception signal.
[0232] The request information is used to request to stop sending the perception signal; or, the request information is used to request to reduce the beamwidth of the perception signal.
[0233] The determination method for the UE to send the request information and the specific description of the request information are the same as the relevant description of any one of the aforementioned communication method of the first device, the communication method of the second device, and the communication method of the core network device. For the sake of brevity, they are not repeated here.
[0234] S830. Base station A forwards the request information to the perception control network element.
[0235] Specifically, the base station A may forward the request information to the perception control network element via a mobility management network element. In FIG8 , the mobility management network element is not shown for simplicity.
[0236] S840. The perception control network element makes a decision based on the request information and generates indication information.
[0237] The specific description of how the perception control network element makes decisions based on the request information is the same as the relevant description in the communication method of the aforementioned core network device, and will not be repeated here for the sake of brevity.
[0238] S850. The perception control network element sends instruction information to base station B.
[0239] The indication information includes one of the following: information for indicating the stopping of the perception service, and the information for indicating the stopping of the perception service is used to determine the stopping of sending the perception signal; information for indicating the continuing of the perception service, and the information for indicating the continuing of the perception service is used to determine the continuing sending of the perception signal, or used to determine the reduction of the beam width of the perception signal; information for indicating the reduction of the beam width of the perception signal, and the information for indicating the continuing of the perception service is used to determine the reduction of the beam width of the perception signal.
[0240] After base station B receives the indication information, it can process the perception signal based on the indication information. The specific processing method is the same as the relevant description in the communication method embodiment of the second device mentioned above, and will not be repeated here for the sake of brevity.
[0241] It should also be understood that the serving base station of the aforementioned first device (i.e., base station A in FIG8 ) and the second device (i.e., base station B in FIG8 ) may be the same base station. The description of the second device being the serving base station of the first device has been described in detail in the aforementioned communication method for the second device and will not be repeated here for the sake of brevity.
[0242] Alternatively, the second device (i.e., base station B in Figure 8) can also be replaced by a terminal device (a terminal device different from the first device). The relevant description of the second device being a terminal device has been described in detail in the aforementioned communication method of the second device, and will not be repeated here for the sake of brevity.
[0243] FIG9 is a schematic diagram of the composition structure of a first device according to an embodiment of the present application, including:
[0244] The first communication unit 901 is configured to send request information; the request information is used to request processing of the perception signal.
