[0155] The following are definitions of the technical terms used in this disclosure:

[0156] 1. TRP: Transmission and Receiving Point.

[0157] 2. RS: Reference Signal, sensing RS means sensing reference signal.

[0158] 3. Rx: Receiver.

[0159] 4. MAC CE: Media Access Control-Control Element.

[0160] 5. RRC: Radio Resource Control.

[0161] 6. TCI: Terminal Control Interface.

[0162] Sensing technologies encompass various types, such as lidar, millimeter-wave radar, and cameras. Camera technologies include any of the following: visual cameras, TOF cameras, sonar detection, infrared detection, and cellular network sensing [e.g., sensing technologies based on 4G (e.g., LTE), 5G (e.g., NR), or 6G cellular network technologies, or future communication technologies]. Cellular network sensing technologies include any of the following: communication base station sensing and communication terminal sensing. Depending on the type of sensing device, the information that can be obtained about the target object includes: coordinate information [e.g., coordinates relative to the wireless signal receiver (e.g., distance, horizontal angle, and vertical angle)]; speed information (e.g., moving speed and direction relative to the wireless signal receiver); signal strength; and behavioral pattern information [e.g., running, walking, approaching, falling, swinging, etc.; or weather information (e.g., rain, snow); or traffic information (e.g., congestion, accidents)].

[0163] Integrated sensing and communications (ISAC): A wireless signal transmitter emits radio waves, and a wireless signal receiver receives them. During the transmission of radio waves, they may be blocked by objects (hereinafter referred to as reflectors), resulting in wireless transmission effects such as reflection, diffraction, transmission, phase change, Doppler shift, and signal strength variation. The wireless signal receiver receives the radio waves and compares the transmitted and received signals, or records the historical changes in the received signal, thereby obtaining information about the reflectors (such as coordinates, velocity, signal strength, and behavioral patterns).

[0164] The "signal transmitter" can be a terminal or a base station, and the "signal receiver" can be a terminal or a base station. The wireless signal transmitter and the wireless signal receiver can originate from the same device or different devices. For example:

[0165] Mode 1: Base station A transmits, base station B receives.

[0166] Mode 2: Base station A transmits, base station A receives.

[0167] Mode 3: Terminal A sends, Terminal B receives.

[0168] Mode 4: Terminal A sends, Terminal A receives.

[0169] Mode 5: Base station A transmits, terminal A receives.

[0170] Mode 6: Terminal A transmits, base station A receives.

[0171] When the wireless signal transmitter and receiver are co-located, this sensing method can be called mono-static sensing. When the wireless signal transmitter and receiver are not co-located, this sensing method can be called bi-static sensing.

[0172] In ISAC technology, during object tracking or area detection, the awareness configuration may need to change dynamically when the object moves or the Rx UE moves. Switching between awareness configuration changes can cause latency, thus affecting service continuity.

[0173] Therefore, this disclosure proposes a communication method, communication device, communication system, storage medium, and program product that configures the sensing configuration information of network devices to reduce the latency caused by the switching when the sensing configuration of the terminal device changes during movement, thereby ensuring the continuity of services.

[0174] Figure 2A is an interactive schematic diagram of a communication method according to an embodiment of the present disclosure. As shown in Figure 2A, the embodiments of the present disclosure relate to a communication method, which includes:

[0175] In embodiments of this disclosure, the access network device includes a first access network device and at least one second access network device. The first access network device is used to determine the terminal device based on sensing configuration information and sensing requests. The at least one second access network device is used to receive initial sensing configuration information sent by the core network device and / or to determine preliminary sensing configuration information for the terminal device to switch sensing configurations.

[0176] Step S2101: The core network device obtains a sensing request.

[0177] In some embodiments, the core network device may obtain a sensing request from the AF (Application Function), the sensing request including at least one of a sensing area and a sensing target, for the core network device to make an initial selection among multiple access network devices.

[0178] In some embodiments, the sensing area is the sensing range, which can be the movement trajectory of the sensing object, and the sensing target can be the sensing object.

[0179] In some embodiments, the core network device may obtain a sensing request by other network nodes sending the sensing request to the core network device, which is not limited in this disclosure.

[0180] For example, AF sends a sensing request to SF, which includes information such as sensing range and sensing object.

[0181] In step S2102, the core network device determines at least one of the first access network device and at least one second access network device.

[0182] In some embodiments, the core network device determines a first access network device based on a sensing request. The first access network device is the access network device currently providing services to the terminal device.

[0183] For example, SF performs TRP selection based on AF's perception request, determining the initial / service TRP.

[0184] In some embodiments, the core network device determines at least one second access network device based on the sensing request. This can be done by selecting at least one second access network device from among multiple access network devices that meets the sensing range. The at least one second access network device is a network device that the core network device initially determines meets the sensing request. It is understood that due to the movement of the terminal device or changes in the environment, some of the at least one second access network device may no longer meet the current terminal device's sensing range, or other network devices may meet the current terminal device's sensing range.

[0185] For example, the SF selects the TRP based on the AF's perception request and determines the candidate TRP.

[0186] In some embodiments, the core network device determines at least one second access network device and a first access network device based on a sensing request.

[0187] For example, SF selects TRPs based on AF's perception request, including initial / service TRPs and preparation TRPs.

[0188] In step S2103, the core network device sends at least one of the following to the first access network device: the initial sensing configuration information of the first access network device, information of at least one second access network device, and a sensing request.

[0189] In some embodiments, the core network device sends initial awareness configuration information to the first access network device to provide awareness configuration to the first access network device.

[0190] In some embodiments, the core network device sends information about at least one second access network device to the first access network device so that the first access network device can determine the network device that the terminal device may switch to, i.e., the access network device to be switched to.

[0191] In some embodiments, the information of at least one second access network device may be the identifier of the second access network device, such as the TRP ID, but is not limited thereto, and may also include other TRP information.

[0192] In some embodiments, the core network device sends a sensing request to the first access network device so that the first access network device can determine the current sensing area and sensing target.

[0193] In some embodiments, the core network device sends the initial sensing configuration information of the first access network device, information of at least one second access network device, and a sensing request to the first access network device so that the first access network device can determine the current sensing area or sensing target range.

[0194] For example, the SF selects a TRP based on the AF perception request and provides perception configuration to the initially selected current TRP, informing it of information such as the ID of other TRPs in the current perception area or perception target range, and that the other TRPs are neighboring cells of the current TRP.

[0195] In some embodiments, the initial sensing configuration information includes at least one of the following: sensing method; sensing range; sensing object; time-frequency resources of the sensing reference signal; and measurement period.

[0196] In some embodiments, the initial sensing configuration information of the first access network device may be the resource range for the first access network device to perform a sensing task.

[0197] In some embodiments, the sensing method can be a single-station sensing method or a dual-station sensing method.

[0198] In some embodiments, the sensing range can be the area covered by the sensing coverage of the access network device.

[0199] In some embodiments, the sensing object can be an object that the access network device can sense or detect.

[0200] In some embodiments, the time-frequency resources of the sensing reference signal can be the resource locations in the time-frequency domain used by the access network device to transmit and receive the sensing reference signal.

[0201] In some embodiments, the measurement period may be the measurement time for measuring the sensing configuration of the access network device, and the measurement period may be different for each access network device.

[0202] In some embodiments, the names of information, etc., are not limited to the names described in the embodiments. Terms such as "information", "message", "signal", "signaling", "report", "configuration", "indication", "instruction", "command", "channel", "parameter", "domain", "field", "symbol", "symbol", "codebook", "codeword", "codepoint", "bit", "data", "program", and "chip" can be used interchangeably.

[0203] In some embodiments, "acquire," "get," "obtain," "receive," "transmit," "bidirectional transmission," and "send and / or receive" can be used interchangeably and can be interpreted as receiving from other entities, acquiring from protocols, acquiring from higher layers, obtaining through self-processing, or autonomous implementation. Protocols include, for example, at least one of the 3GPP protocol, Wi-Fi protocol, and audio and / or video protocols.

[0204] In some embodiments, terms such as “send,” “transmit,” “report,” “distribute,” “transfer,” “bidirectional transmission,” “send and / or receive” can be used interchangeably.

[0205] In some embodiments, terms such as "certain," "preset," "default," "set," "indicated," "a certain," "any," and "first" can be used interchangeably. "Certain A," "preset A," "default A," "set A," "indicated A," "a certain A," "any A," and "first A" can be interpreted as A pre-defined in a protocol or the like, or as A obtained through setting, configuration, or instruction, or as specific A, a certain A, any A, or first A, but are not limited thereto.

[0206] In step S2104, the first access network device determines the terminal device and the configuration information for the terminal device to perform sensing.

[0207] In some embodiments, the first access network device determines the terminal device and the terminal device's configuration information for performing sensing based on the initial sensing configuration information and the sensing request.

[0208] In some embodiments, the first access network device selects a terminal device for sensing based on the initial sensing configuration and sensing request, and configures the terminal device to perform sensing configuration information.

[0209] For example, the current TRP selects the UE for sensing based on the SF's sensing request and sensing configuration requirements, and configures the sensing parameters.

[0210] In some embodiments, the first access network device determines the terminal device based on the principle of satisfying the sensing area and being able to detect the sensing target in the sensing request, and determines the terminal device used for sensing based on the implementation. The determined terminal device is the device that satisfies the sensing target.

[0211] In some embodiments, the configuration information for the terminal device to perform sensing may be initial sensing configuration information, including sensing method, sensing range, sensing object, time-frequency resources of sensing reference signal, measurement period, and switching point for the terminal device to switch to the access network device.

[0212] In some embodiments, the configuration information for the terminal device to perform sensing can be determined by adjusting the initial sensing configuration information configured by the core network device based on the current time and frequency resources, including the scheduling of the terminal device.

[0213] Step S2105: The first access network device sends configuration information to the terminal device.

[0214] In some embodiments, the first access network device sends the terminal device the configuration information for performing sensing on the terminal device, so that the terminal device can adjust the sensing configuration.

[0215] For example, the current / initial / serving TRP sends configuration parameters to the UE, which are obtained by adjusting the range based on the SF configuration.

[0216] Step S2106: The first access network device sends terminal device information to at least one second access network device.

[0217] In some embodiments, the information of the terminal device includes at least one of the terminal device's identifier, the terminal device's location, and sensing parameters measured by the terminal device.

[0218] In some embodiments, the first access network device sends information about the terminal device to at least one second access network device so that the second access network device can determine the terminal device that may switch to its own cell.

[0219] In some embodiments, the information of the terminal device may be sent by the terminal device to a first access network device, and then sent by the first access network device to at least one second access network device.

[0220] In some embodiments, the information of the terminal device may be sent by the terminal device to the core network device, and then sent by the core network device to at least one second access network device.

[0221] In some embodiments, the sensing parameters measured by the terminal device include information such as the moving direction, moving speed, and position of the terminal device.

[0222] For example, the serving TRP will transmit the UE ID, UE location information, and UE perception parameters of the selected UE to the neighboring cell TRP through the inter-base station / inter-TRP interface.

[0223] Step S2107: The terminal device sends sensing parameters to the core network device.

[0224] In some embodiments, the sensing parameters include at least one of the following: the position of the terminal device; the moving speed of the terminal device; the moving direction of the terminal device; the position of the sensing target; the moving speed of the sensing target; and the moving direction of the sensing target.

[0225] In some embodiments, the terminal device sends its own sensing parameters to the core network device so that the core network device can obtain real-time terminal sensing parameters and other information.

[0226] In some embodiments, the terminal device can send the data directly to the core network device, or it can first send the data to the first access network device, which will then pass it through to the core network device.

[0227] For example, the UE reports sensing parameters and information to the SF, such as the direction of movement, speed of movement, and location information of the sensed object / sensor, and / or the UE's own location, speed, and direction of movement.

[0228] In step S2108, the core network device determines the initial sensing configuration information of at least one second access network device.

[0229] In some embodiments, the core network device determines the initial sensing configuration information of at least one second access network device based on sensing parameters.

[0230] In some embodiments, the core network device may determine at least one second access network device based on the sensing parameters, which may be the same as or different from the at least one second access network device determined in step S2102. In other words, the at least one second access network device initially determined in step S2102 will be further filtered in step S2108 based on the sensing parameters to determine at least one second access network device that meets the sensing parameters. The at least one second access network device further determined may include the second access network device determined in step S2102, and may also include other access network devices.

[0231] In some embodiments, the core network device may determine at least one second access network device based solely on the sensing parameters, and determine the initial sensing configuration information of the at least one second access network device. In other words, in step S2102, the core network device only determines the first access network device, and does not determine the second access network device. This is because after the terminal device sends the sensing parameters, the core network device directly determines at least one second access network device that currently meets the sensing parameters based on the sensing parameters.

[0232] For example, there may be two schemes for the SF to determine the reserve TRP. Scheme 1: The SF initially determines at least one candidate TRP based on the perception request, and after the UE reports the perception parameters and other information, it dynamically determines at least one reserve TRP based on the perception parameters. The reserve TRP may be among the at least one candidate TRP or other TRPs. Scheme 2: The SF determines the serving TRP based on the perception request, but does not determine the reserve TRP. After the UE reports the perception parameters and other information, it dynamically determines at least one reserve TRP based on the perception parameters.

[0233] In some embodiments, the initial sensing configuration information of the second access network device includes at least one of the following: the coverage area of ​​the second access network device; the switching point for the terminal device to switch to the second access network device; the sensing method; the sensing range; the sensing object; the time-frequency resources of the sensing reference signal; and the measurement period.

[0234] In some embodiments, the coverage area of ​​the second access network device can be the area that the second access network device can perceive.

[0235] In some embodiments, the switching point for a terminal device to switch to a second access network device may include information such as the switching location and switching time. In other words, the switching point includes a time dimension and a spatial dimension. The spatial dimension may be the coverage area of ​​the two second access network devices; the time dimension may be the approximate time of arrival at the switching point determined based on the moving speed and direction of the terminal device.

[0236] In some embodiments, the sensing method can be a single-station sensing method or a dual-station sensing method.

[0237] In some embodiments, the sensing range may be the area covered by the sensing coverage of the second access network device.

[0238] In some embodiments, the sensing object may be an object that the second access network device can sense or detect.

[0239] In some embodiments, the time-frequency resources of the sensing reference signal can be the resource locations in the time-frequency domain used by the second access network device to transmit and receive the sensing reference signal.

[0240] In some embodiments, the measurement period may be the measurement time for measuring the sensing configuration of the second access network device, and the measurement period for each second access network device may be different.

[0241] For example, the SF calculates the coverage range, handover point, and initial perception parameters of different prepared TRPs based on the perception parameters and information reported by the UE. The SF can also pre-configure the coverage range of different prepared TRPs according to perception requirements, and configure the handover point and the initial perception parameters of different TRPs according to the UE / detected object perception information.

[0242] In step S2109, the core network device sends initial sensing configuration information to at least one second access network device.

[0243] In some embodiments, the core network device sends initial awareness configuration information to at least one second access network device for the second access network device to prepare for the terminal device to hand over to its local cell.

[0244] For example, SF configures initial sensing parameters to the prepared TRP.

[0245] In step S2110, the second access network device determines the pre-sensing configuration information.

[0246] In some embodiments, the second access network device determines preliminary sensing configuration information for the terminal device to adjust its sensing configuration based on the initial sensing configuration information.

[0247] In some embodiments, the pre-sensing configuration information includes at least one of the following: the coverage area of ​​the access network device; the beam angle range corresponding to the coverage area of ​​the access network device; the arrival angle of the signal sent by the access network device to the terminal device; the service time of the access network device; the handover point of the terminal device to the access network device; the sensing method; the sensing range; the sensing object; the time and frequency resources of the sensing reference signal; and the measurement period.

[0248] In some embodiments, the pre-sensing configuration information may be related information of the sensing configuration obtained by the second access network device after adaptive adjustment based on the initial sensing configuration information and the current environment, and may be used by the terminal device to switch to itself to perform sensing related configuration information.

[0249] In some embodiments, the pre-sensing configuration information determined by the second access network device includes at least one of the following: the coverage area of ​​the second network device; the beam angle range corresponding to the coverage area of ​​the second network device; the arrival angle of the signal sent by the second network device to the terminal device; the service time of the second network device; the switching point of the terminal device switching to the second network device; the sensing method; the sensing range; the sensing object; the time-frequency resources of the sensing reference signal; and the measurement period.

[0250] In some embodiments, the preliminary sensing configuration information is information related to the sensing configuration of the terminal device reaching the coverage area of ​​the second access network device, which is further determined by the second access network device based on the initial sensing configuration information.

[0251] For example, the pre-TRP further provides the UE's perception configuration for reaching the TRP's coverage area based on the SF configuration, including the pre-TRP's coverage area, the beam angle range corresponding to the coverage area, the arrival angle of the UE's received signal, service time, handover time, etc.

[0252] In some embodiments, the relevant parameters in the pre-sensing configuration information may be the same as or different from the object parameters in the initial sensing configuration information. The second access network device will dynamically adjust the initial sensing configuration information according to the sensing parameters of the terminal device so that the second access network device can meet the sensing requirements of the terminal device.

[0253] In some embodiments, the beam angle range corresponding to the coverage area of ​​the second access network device can be the angle between the area that the second access network device can sense and the location of the second access network device. In other words, the sensing area of ​​the second access network device is a fan-shaped area, and its fan angle is the beam angle range corresponding to the coverage area of ​​the second access network device.

[0254] Step S2111: The second access network device sends pre-sensing configuration information to the first access network device.

[0255] In some embodiments, the second access network device sends pre-sensing configuration information to the first access network device so that the terminal device can adjust its sensing configuration.

[0256] In some embodiments, the second access network device sends at least one pre-sense configuration information of the second access network device to the first access network device, so that the first access network device can obtain the relevant sense configuration of the access network device to be switched to that the terminal device may switch to.

[0257] In some embodiments, the second access network device can send pre-sense configuration information to the first access network device through the core network device, that is, the second access network device sends pre-sense configuration information to the core network device, and the core network device sends pre-sense configuration information to the first access network device.

[0258] In some embodiments, the second access network device may send pre-awareness configuration information to the first access network device through a network interface with the first access network device.

[0259] For example, the preparatory TRP further provides the UE with the perception configuration of arriving at the coverage area of ​​the TRP according to the SF configuration, and informs the current serving TRP about the coverage area of ​​the preparatory TRP, the beam angle range corresponding to the coverage area, the arrival angle of the UE's received signal, the service time, the handover time, etc. through the base station / TRP interface.

[0260] In step S2112, the first access network device sends pre-sensing configuration information to the terminal device.

[0261] In some embodiments, the first access network device sends pre-sense configuration information to the terminal device so that the terminal device can adjust the sense configuration based on the pre-sense configuration information to perform cell handover, thereby reducing the latency of sense configuration handover.

[0262] In some embodiments, the first access network device sends at least two sensing configuration information to the terminal device. The at least two sensing configuration information are at least two pre-sensing configuration information of the second access network device, and different pre-sensing configuration information correspond to different second access network devices.

[0263] For example, the current serving TRP sends the pre-aware configuration of the current-aware UE to the UE corresponding to all pre-aware TRPs.

[0264] In step S2113, the core network equipment determines the access network equipment to be switched.

[0265] In some embodiments, the core network device determines the access network device to be switched from at least one second access network device based on sensing parameters.

[0266] In some embodiments, the core network device can determine, from at least one second access network device, an access network device that meets the terminal device's sensing parameters based on the sensing parameters sent by the terminal device, so that the terminal device can adjust its sensing configuration. In other words, adjusting the sensing configuration is equivalent to switching the sensing configuration, and the switching of the sensing configuration is determined by the core network device, that is, the core network device notifies the terminal device of the switching target for the sensing configuration.

[0267] For example, the SF / network decides to switch TRPs based on the perception information reported by the UE.

[0268] In step S2114, the core network device sends information about the access network device to be switched to at least one of the terminal device and the first access network device.

[0269] In some embodiments, the core network device sends first information to at least one of the terminal device and the first access network device, the first information including information about the access network device to be switched.

[0270] In some embodiments, the core network device sends information related to the handover target of the handover awareness configuration to at least one of the terminal device and the first access network device for use in the handover awareness configuration of the terminal device.

[0271] In some embodiments, the information of the access network device to be switched includes the identification information of the access network device to be switched, the pre-sense configuration information of the access network device to be switched, and other information.

[0272] In some embodiments, the information of the access network device to be switched may include the identification information of the terminal device. In other words, when there are multiple terminal devices, the core network device needs to send the information of the access network device to be switched to multiple terminal devices.

[0273] In some embodiments, the preliminary sensing configuration information of the access network device to be switched includes at least one of the following: the coverage area of ​​the access network device; the beam angle range corresponding to the coverage area of ​​the access network device; the arrival angle of the signal sent by the access network device to the terminal device; the service time of the access network device; the switching point of the terminal device switching to the access network device; the sensing method; the sensing range; the sensing object; the time and frequency resources of the sensing reference signal; and the measurement period.

[0274] For example, the SF / network decides to switch TRPs based on the perception information reported by the UE and informs the UE to switch perception configurations. The notification may include the TRPID to be switched. The SF also informs the current TRP of the perception configuration switch for the current perception UE.

[0275] In some embodiments, the core network device may send information about the access network device to be switched to the terminal device through the following signaling: physical layer indication, MAC CE, RRC, direct link between UE and awareness control node, and user plane.

[0276] In the above embodiments, the core network device can determine a first access network device based on a sensing request, and determine at least one second access network device based on sensing parameters sent by the terminal device, configure sensing configuration information for at least one second access network device, and determine the access network device to be switched; or the core network device can determine a first access network device and at least one second access network device based on a sensing request, and further filter at least one second access network device based on sensing parameters sent by the terminal device, configure sensing configuration information for at least one second access network device, and determine the access network device to be switched, so that the terminal device can switch the sensing configuration between the access network device to be switched and the first access network device based on the instructions of the core network device.

[0277] The communication method involved in the embodiments of this disclosure may include at least one of steps S2101 to S2104. For example, step S2101 can be implemented as a standalone embodiment, step S2102 can be implemented as a standalone embodiment, steps S2101+S2102, S2101+S2102+S2103 can be implemented as standalone embodiments, steps S2101+S2102+S2103+S2104, steps S2101+S2102+S2103+S2104+S2105, steps S2101+S2102+S2103+S2104+S2105+S2107, and steps S2101+S2102+S2103+S2104+S2105+S2107+S2108+S2109+S ... 2108, Step S2101+S2102+S2103+S2104+S2105+S2107+S2108+S2109, Step S2101+S2102+S2103+S2104+S2105+S2107+S2108+S2109+S2110, Step S2101+S2102+S2103+S2104+S2105+S2107+S2108+S2109+S2110+S2111, Step S2101+S2102+S2103+S2104+S2105+S2107+S2108+S2109+S2 110+S2111+S2112, step S2101+S2102+S2103+S2104+S2105+S2107+S2108+S2109+S2110+S2111+S2112+S2113, step S2101+S2102+S2103+S2104+S2105+S2107+S2108+S2109+S2110+S2111+S2112+S2113+S2114, step S2101+S2102+S2103+S2104+S2106+S2105+S2107, step S2101+S21 02+S2103+S2104+S2105+S2106+S2107+S2108, step S2101+S2102+S2103+S2104+S2105+S2106+S2107+S2108+S2109, step S2101+S2102+S2103+S2104+S2105+S2106+S2107+S2108+S2109+S2110, step S2101+S2102+S2103+S2104+S2105+S2106+S2107+S2108+S2109+S2110+S2111,Steps S2101+S2102+S2103+S2104+S2105+S2106+S2107+S2108+S2109+S2110+S2111+S2112, Steps S2101+S2102+S2103+S2104+S2105+S2106+S2107+S2108+S2109 Steps S2110, S2111, S2112, S2113, S2101, S2102, S2103, S2104, S2105, S2106, S2107, S2108, S2109, S2110, S2111, S2112, S2113, and S2114 can be implemented as independent embodiments, but are not limited thereto.

[0279] Figure 2B is an interactive schematic diagram of a communication method according to an embodiment of the present disclosure. As shown in Figure 2B, the embodiments of the present disclosure relate to a communication method, which includes:

[0280] In embodiments of this disclosure, the access network device includes a first access network device and at least one second access network device. The first access network device is used to determine a terminal device based on sensing configuration information and a sensing request. The at least one second access network device is used to receive initial sensing configuration information sent by the first access network device and determine preliminary sensing configuration information for the terminal device to switch sensing configurations.

[0281] Step S2201: The core network device obtains a sensing request.

[0282] In some embodiments, a sensing request includes at least one of a sensing area and a sensing target.

[0283] In some embodiments, the specific implementation of the core network device obtaining the perception request can be found in the optional implementation of step S2101 in Figure 2A, and will not be repeated here.

[0284] In step S2202, the core network device determines at least one of the first access network device and at least one second access network device.

[0285] In some embodiments, the specific implementation of step S2202 can be found in the optional implementation of step S2102 in FIG2A, and will not be repeated here.

[0286] In step S2203, the core network device sends at least one of the following to the first access network device: the initial sensing configuration information of the first access network device, information of at least one second access network device, and a sensing request.

[0287] In some embodiments, the specific implementation of step S2203 can be found in the optional implementation of step S2103 in FIG2A, and will not be repeated here.

[0288] In step S2204, the first access network device determines the terminal device and the configuration information for the terminal device to perform sensing.

[0289] In some embodiments, the specific implementation of step S2204 can be found in the optional implementation of step S2104 in FIG2A, which will not be repeated here.

[0290] Step S2205: The first access network device sends configuration information to the terminal device.

[0291] In some embodiments, the specific implementation of step S2205 can be found in the optional implementation of step S2105 in FIG2A, and will not be repeated here.

[0292] Step S2206: The first access network device sends terminal device information to at least one second access network device.

[0293] In some embodiments, the specific implementation of step S2206 can be found in the optional implementation of step S2106 in FIG2A, and will not be repeated here.

[0294] Step S2207: The terminal device sends sensing parameters to the core network device.

[0295] In some embodiments, the specific implementation of step S2207 can be found in the optional implementation of step S2107 in FIG2A, and will not be repeated here.

[0296] In step S2208, the core network device determines the initial sensing configuration information of at least one second access network device.

[0297] In some embodiments, the specific implementation of step S2208 can be found in the optional implementation of step S2108 in FIG2A, and will not be repeated here.

[0298] In step S2209, the core network device sends initial sensing configuration information to at least one second access network device.

[0299] In some embodiments, the specific implementation of step S2209 can be found in the optional implementation of step S2109 in FIG2A, and will not be repeated here.

[0300] Step S2210: The second access network device determines the pre-sensing configuration information.

[0301] In some embodiments, the specific implementation of step S2210 can be found in the optional implementation of step S2110 in FIG2A, and will not be repeated here.

[0302] Step S2111: The second access network device sends pre-sensing configuration information to the first access network device.

[0303] In some embodiments, the specific implementation of step S2211 can be found in the optional implementation of step S2111 in FIG2A, and will not be repeated here.

[0304] Step S2212: The first access network device determines the first condition.

[0305] In some embodiments, the first access network device determines a first condition for the terminal device to adjust its sensing configuration based on the pre-sensing configuration information.

[0306] In some embodiments, the first condition includes at least one of the following: exceeding the coverage range or coverage angle of the currently connected access network device; the angle of arrival of the received signal exceeding a threshold; the handover time; or reaching the coverage range of an adjacent access network device.

[0307] In step S2213, the first access network device sends pre-sensing configuration information and the first condition to the terminal device.

[0308] In some embodiments, the first access network device sends at least two sensing configuration information pieces and a first condition to the terminal device, with different sensing configuration information pieces corresponding to different access network devices. In other words, the at least two sensing configuration information pieces are at least two preliminary sensing configuration information pieces, with different preliminary sensing configuration information pieces corresponding to different second access network devices.

[0309] In some embodiments, the first condition is used by the terminal device to switch the sensing configuration based on the received first condition.

[0310] In some embodiments, the terminal device receives a first condition sent by the first access network device to enable the terminal device to adjust the sensing configuration when the first condition is met, wherein the first condition is a pre-configuration condition for adjusting the sensing configuration.

[0311] For example, the current serving TRP sends the pre-aware configuration of the current aware UE to all pre-aware TRPs and provides handover conditions for each pre-aware configuration. The handover conditions may include: exceeding the coverage range or coverage angle of the current connected TRP; the angle of arrival of the received signal exceeding a certain threshold; the handover time is reached; or the coverage range of an adjacent TRP is reached.

[0312] Step S2214: The terminal device determines the access network device to be switched.

[0313] In some embodiments, the terminal device switches the sensing configuration according to a first condition, which may be to determine the access network device to be switched from at least one second access network device.

[0314] In some embodiments, determining the access network device to be switched may involve determining the identification information of the access network device that is sense-paired with the terminal device and / or the sense-pairing information of the terminal device, wherein the sense-pairing information includes the identification information of the terminal device and the identification information of the access network device that is paired with it.

[0315] For example, the UE determines the TRP paired with the UE based on the handover conditions. That is, when the UE switches the awareness configuration, it needs to determine the current UE's switching configuration / TRP ID / TCI / awareness pair, where the awareness pair is the relationship between the UE ID and the TRP ID.

[0316] In step S2215, the terminal device sends handover information to the first access network device.

[0317] In some embodiments, the handover information includes information about the access network device to be handed over, which the terminal device determines from at least one second access network device, so that the terminal device can hand over from the first access network device to the access network device to be handed over.

[0318] In some embodiments, the terminal device sending handover information to the first access network device includes sending the identification information of the access network device to be handed over and / or the sensing pairing information between the terminal device and the access network device to be handed over, wherein the sensing pairing information includes the identification information of the terminal device and the identification information of the access network device to which it is sensingly paired.

[0319] For example, the UE sends the current UE's configuration / TRP ID / TCI / perceptual peer information to the serving TRP.

[0320] In some embodiments, the terminal device handover awareness configuration may be a handover from a first access network device to an access network device to be handed over.

[0321] In the above embodiments, based on at least two pre-sensing configuration information and a first condition, the terminal device can further determine the access network device to be switched to in the switching sensing configuration, so as to realize the switch from the first access network device to the access network device to be switched, and avoid the switching delay caused by the movement of the terminal device.

[0322] The communication method involved in the embodiments of this disclosure may include at least one of steps S2201 to S2205. For example, step S2201 can be implemented as a standalone embodiment, step S2202 can be implemented as a standalone embodiment, steps S2201+S2202, steps S2201+S2202+S2203 can be implemented as standalone embodiments, steps S2201+S2202+S2203+S2204, steps S2201+S2202+S2203+S2204+S2205, steps S2201+S2202+S2203+S2204+S2205+S2206, steps S2201+S2202+S2203+S2204+S2205+S2207, and steps S2201+S2202+S2203+S2204+S2205+S2207. 2202+S2203+S2204+S2205+S2206+S2207, step S2201+S2202+S2203+S2204+S2205+S2207+S2208, step S2201+S2202+S2203+S2204+S2205+S2206+S2207+S2208, step S2201+S2202+S2203+S2204+S2205+S2207+S2208+S2209, step S2201+S2202+S2203+S2204+S2205+S2206+S2207+S2208+S220 9.

[0323] In some embodiments, the steps and their optional implementations in other embodiments described before or after this embodiment, as well as other related parts in the specification, can be referred to, and will not be repeated here.

[0324] Figure 2C is an interactive schematic diagram of a communication method according to an embodiment of the present disclosure. As shown in Figure 2C, the embodiments of the present disclosure relate to a communication method, which includes:

[0325] In embodiments of this disclosure, there are at least two access network devices, which are used to receive information from the terminal device and pre-sensing configuration information.

[0326] Step S2301: The core network device obtains a sensing request.

[0327] In some embodiments, a sensing request includes at least one of a sensing area and a sensing target.

[0328] In some embodiments, the specific implementation of the core network device obtaining the perception request can be found in the optional implementation of step S2101 in Figure 2A or step S2201 in Figure 2B, and will not be repeated here.

[0329] In step S2302, the core network equipment identifies at least two access network devices.

[0330] In some embodiments, the core network device determines at least two access network devices based on a sensing request.

[0331] In some embodiments, the core network device may determine at least two access network devices by selecting at least two access network devices that meet the sensing range from among a plurality of network devices. The at least two access network devices are the network devices that the core network device initially determines meet the sensing request.

[0332] For example, SF selects multiple alternative TRPs based on sensing requirements (sensing range, sensing object movement trajectory).

[0333] In step S2303, the core network device sends a sensing request to at least two access network devices.

[0334] In some embodiments, the core network device sends a sensing request to at least two access network devices to inform them that sensing configuration is required.

[0335] For example, SF sends sensing requirements to multiple alternative TRPs.

[0336] Step S2304: The access network device sends initial perception configuration information to the core network device.

[0337] In some embodiments, at least two access network devices send initial sensing configuration information to the core network device in response to a sensing request.

[0338] In some embodiments, the initial sensing configuration information includes at least one of the following: a list of candidate terminal devices corresponding to the access network device; the coverage area of ​​the access network device; the switching point for switching from the terminal device to the access network device; the sensing method; the sensing range; the sensing object; the time-frequency resources of the sensing reference signal; and the measurement period.

[0339] For example, multiple alternative TRPs report a list of alternative target UEs and configurable perception parameters based on SF perception requirements.

[0340] Step S2305: The core network equipment determines the terminal equipment, the pre-sensing configuration information, and the first information.

[0341] In some embodiments, the core network device determines a terminal device shared by at least two access network devices, pre-sensing configuration information of at least two access network devices, and first information.

[0342] In some embodiments, the core network device may determine the terminal device by identifying a common terminal device based on a list of candidate terminal devices corresponding to at least two access network devices.

[0343] For example, SF selects a common UE as the perception Rx based on the list of candidate target UEs reported by multiple alternative TRPs.

[0344] In some embodiments, the core network device determining the pre-awareness configuration information of at least two access network devices may involve determining the pre-awareness configuration information of each access network device.

[0345] In some embodiments, the pre-sense configuration information may be related information of the sense configuration obtained by the core network device after adjusting the initial sense configuration information based on the initial sense configuration information and the relevant information of the current environment and the terminal device. It can be used by the terminal device to switch to different access network devices to execute the relevant configuration information of sense.

[0346] In some embodiments, the pre-sensing configuration information includes at least one of the following: the coverage area of ​​the access network device; the beam angle range corresponding to the coverage area of ​​the access network device; the arrival angle of the signal received by the terminal device; the service time of the access network device; the handover point of the terminal device to the access network device; the sensing method; the sensing range; the sensing object; the time and frequency resources of the sensing reference signal; and the measurement period.

[0347] In some embodiments, the measurement period is the time period for sensing and measuring access network devices, and the measurement period for each access network device may be different.

[0348] In some embodiments, the core network device determines first information based on at least two preliminary sensing configuration information. The first information includes a sensing range. It is understood that the sensing range in the first information is different from the sensing range in the initial sensing configuration information or the preliminary sensing configuration information. The sensing range in the first information may refer to the joint sensing range corresponding to at least two access network devices. The sensing range in the sensing configuration refers to the range to be sensed corresponding to the sensing request, or the sensing range corresponding to the access network device, or the sensing range corresponding to the terminal device, or the sensing range where the sensing object is located, etc.

[0349] In some embodiments, the first information determined by the core network device may include a joint sensing range, which is used by the terminal device to perform sensing measurements or collaborative sensing within the joint sensing range.

[0350] In step S2306, the core network device sends terminal device information and pre-sensing configuration information to at least two access network devices.

[0351] In some embodiments, the relevant information of the terminal device includes the terminal device's identification information, etc.

[0352] In some embodiments, the pre-sensing configuration information may be the pre-sensing configuration information of at least two access network devices.

[0353] For example, SF sends relevant information about the sensed Rx, such as the sensed Rx ID, to multiple alternative TRPs.

[0354] In step S2307, the core network equipment sends pre-sensing configuration information and first information to the terminal equipment.

[0355] In some embodiments, the core network device sending at least two sensing configuration information to the terminal device may be sending at least two access network device pre-sensing configuration information to the terminal device, so that the terminal device can adjust the sensing configuration among at least two access network devices.

[0356] In some embodiments, the core network device sending first information to the terminal device may be sending a sensing range or a joint sensing range to the terminal device. The joint sensing range is used by the terminal device to perform sensing measurements within the joint sensing range.

[0357] In some embodiments, the joint sensing range can be the intersection of the sensing ranges of at least two access network devices, that is, the terminal device can transmit and receive sensing signals with at least two access network devices within this range.

[0358] For example, the SF sends the perception configuration information of multiple alternative TRPs and the joint perception range of the multiple perception configurations to the UE.

[0359] In some embodiments, the core network device sends first information and pre-awareness configuration information to the terminal device through at least one of the following: physical layer indication, MAC CE, RRC, direct link between UE and awareness control node, and working plane.

[0360] Step S2308: The terminal device performs sensing measurements.

[0361] In some embodiments, the terminal device performs sensing measurements on the device under test in at least two access network devices based on the measurement period in the sensing configuration information, and determines the sensing measurement results.

[0362] In some embodiments, any one of the at least two access network devices is the device to be measured.

[0363] In some embodiments, the terminal device performs sensing measurements according to the measurement cycle corresponding to each access network device, that is, according to the measurement cycle of each device to be measured.

[0364] For example, the UE periodically switches between multiple alternative TRPs. For instance, it can be cyclical, with period 1 measuring the perception configuration of TRP1 and period 2 measuring the perception configuration of TRP2; or it can be periodic, for example, measuring TRP1 every first interval and TRP2 every second interval, with no overlap between them.

[0365] In some embodiments, the terminal device performs sensing measurements on at least two access network devices, and the sensing measurement result is considered a failure when the terminal device moves beyond the joint sensing range.

[0366] In some embodiments, the terminal device performs sensing measurements on at least two access network devices. When the terminal device moves into the sensing range of the access network device to be switched, and the sensing measurement result is successful, the terminal device can switch the sensing configuration between the currently connected access network device and the access network device to be switched. Step S2309: The terminal device sends the sensing measurement result to the access network device.

[0367] In some embodiments, the terminal device sends the sensing measurement results to at least one of the current service device and the device to be measured in at least two access network devices.

[0368] In some embodiments, adjusting the sensing configuration based on first information and a first condition includes: reconfiguring the sensing configuration when the sensing range is exceeded. The first condition is exceeding the sensing range, and the first condition is a pre-configuration condition used to adjust the sensing configuration.

[0369] In some embodiments, reconfiguring the sensing system when the sensing range is exceeded can be achieved by the core network device reconfiguring the sensing system for the terminal device when the terminal device fails to perform sensing measurements.

[0370] In some embodiments, the terminal device may send sensing measurement results to the device under test, which is the access network device currently performing sensing measurement on the terminal device.

[0371] For example, when a UE moves beyond the joint sensing range of multiple sensing configurations, the UE reports a sensing link failure to the TRP currently performing the sensing measurement, or the network reconfigures based on the measurement results. In some embodiments, if the sensing measurement fails, the terminal device may send the sensing measurement results to a first access network device, which is the current serving device currently providing services to the terminal device.

[0372] For example, if a UE moves beyond the joint sensing range of multiple sensing configurations, the UE reports a sensing link failure to the current serving TRP.

[0373] In the above embodiments, the core network device provides the terminal device with at least two sensing configuration information and sensing range. The terminal device can perform sensing measurements on at least two access network devices corresponding to the at least two sensing configuration information to reduce the handover latency that may be caused by switching sensing configurations.

For example, step S2301 may be implemented as a standalone embodiment, step S2302 may be implemented as a standalone embodiment, and steps S2301+S2302, S2301+S2302+S2303, S2301+S2302+S2303+S2304, S2301+S2302+S2303+S2304+S2305, and S2301+S2302+S2303+S2304+S2305+S2309 may be implemented as a standalone embodiment.

[0400] The following are specific solutions proposed in the embodiments of this disclosure:

[0401] 1. The network configures multiple sensing configurations for the sensing UE, and the UE switches between multiple sensing configurations.

[0402] 1. The network dynamically informs the UE to switch between multiple configurations based on the UE's perception measurement information, location information, and mobility information.

[0403] Figure 4A shows an interaction diagram of Example 1. The network pre-configures multiple sensing configurations to the UE, and the steps are as follows:

[0404] Step 1: SF obtains a perception request (carrying information such as perception range and perception object).

[0405] Step 1a: SF selects TRP based on AF perception request.

[0406] Step 1b: Provide sensing configuration to the initially selected TRP. Simultaneously, the SF informs the TRP of other TRP information (such as ID) corresponding to the current sensing area or sensing target range. Other TRPs can be neighboring cells of the current TRP.

[0407] Step 2: TRP selects the UE for sensing based on SF's request and configuration requirements.

[0408] Step 2a: Configure the sensing parameters for the UE.

[0409] Step 3: The TRP will select the UE ID, UE location information, and UE perception parameters and pass them to the neighboring cell TRP through the inter-base station / inter-TRP interface.

[0410] Step 4: The UE reports the sensing parameters and information to the SF.

[0411] Step 4a: The SF calculates the coverage area, handover point, and initial perception parameters of different pre-reserved TRPs based on the perception parameters and information reported by the UE (such as object movement direction, speed, and location information) and / or the UE's own location, speed, and movement direction. The SF can also pre-configure the coverage area of ​​different pre-reserved TRPs according to perception requirements, and configure the handover point and initial perception parameters of different TRPs according to the UE / detected object perception information.

[0412] Step 4b: SF configures initial sensing parameters to the preparatory TRP.

[0413] Step 5: Prepare the TRP to further provide the UE with the awareness configuration for reaching the coverage area of ​​the TRP based on the SF configuration.

[0414] Step 5a: The preparatory TRP informs the current serving TRP about the coverage area of ​​the preparatory TRP, the beam angle range corresponding to the coverage area, the arrival angle of the UE's received signal, the service time, and the handover time through the inter-base station / inter-TRP interface.

[0415] Step 6: The current service TRP sends the pre-aware configuration of the current awareness UE to the UE corresponding to all pre-aware TRPs.

[0416] Step 7: The SF / network decides to switch TRPs based on the perception information reported by the UE.

[0417] Step 7a: The SF informs the UE to switch the perception configuration. The notification content can include the perception configuration ID, TRPID, etc.

[0418] Step 7b: SF simultaneously informs the current TRP of the perception configuration switch for the current perception UE.

[0419] The network can inform the terminal via the following signaling: physical layer indication; MAC CE; RRC; direct link between the UE and the sensing control node; through the user plane.

[0420] The optional implementation of Embodiment 1 can be found in the optional implementations of steps S2101-S2114 in Figure 2A.

[0421] 2. The UE can switch autonomously between multi-sensory configurations based on the network pre-configuration conditions.

[0422] Figure 4B is an interactive schematic diagram of Example 2. The network pre-configures multiple sensing configurations to the UE, and the steps are as follows:

[0423] Step 1: SF obtains a perception request (carrying information such as perception range and perception object).

[0424] Step 1a: SF selects TRP based on AF perception request and provides perception configuration for the initially selected TRP.

[0425] Step 1b: The SF informs the TRP of other TRP information (such as ID) corresponding to the current sensing area or sensing target range. Other TRPs can be neighboring cells of the current TRP.

[0426] Step 2: TRP selects the UE for sensing based on SF's request and configuration requirements.

[0427] Step 2a: TRP configures awareness parameters for UE.

[0428] Step 3: The TRP will select the UE ID, UE location information, and UE perception parameters and pass them to the neighboring cell TRP through the inter-base station / inter-TRP interface.

[0429] Step 4: The UE sends sensing parameters and information to the SF.

[0430] Step 4a: The SF calculates the coverage area of ​​different preliminary TRPs, handover points, and initial sensing parameters based on the sensing parameters and information reported by the UE (such as the object's movement direction, speed, and location information) and / or the UE's own location, speed, and movement direction.

[0431] Step 4b: SF can also pre-configure the coverage range of different pre-reserved TRPs according to the perception requirements, and configure the handover point and the initial perception parameters of different TRPs according to the UE / detected object perception information.

[0432] Step 5: Prepare the TRP to further provide the UE with the awareness configuration for reaching the coverage area of ​​the TRP based on the SF configuration.

[0433] Step 5a: The preparatory TRP informs the current serving TRP about the coverage area of ​​the preparatory TRP, the beam angle range corresponding to the coverage area, the arrival angle of the UE's received signal, the service time, and the handover time through the inter-base station / inter-TRP interface.

[0434] Step 6: The current serving TRP sends the pre-aware configurations of all pre-aware TRPs corresponding to the currently aware UE to the UE, and provides handover conditions for each pre-aware configuration. The handover conditions may include: exceeding the coverage range or coverage angle of the currently connected TRP; the angle of arrival of the received signal exceeding a certain threshold; reaching the handover time; reaching the coverage range of an adjacent TRP.

[0435] Step 6a: The UE determines the target TRP based on the handover conditions.

[0436] Step 7: When the UE switches the perception configuration, inform the network of the current UE's switching configuration / TRPID / TCI / perception peer information.

[0437] The optional implementation of Embodiment 2 can be found in the optional implementations of steps S2201-S2215 in Figure 2B.

[0438] Second, the SF provides the UE with multiple sensing configurations and the combined sensing range of these configurations. The UE performs collaborative sensing based on multiple sensing configurations. If the sensing range exceeds the combined range of multiple configurations, the UE reports a sensing link failure, or the network reconfigures the settings based on the measurement results.

[0439] Figure 4C is an interactive schematic diagram of Example 3:

[0440] Step 1: SF acquires perception requirements (perception range, perceived object movement trajectory).

[0441] Step 1a: SF selects multiple TRPs based on perception requirements.

[0442] Step 1b: SF sends sensing requests to multiple TRPs.

[0443] Step 2: Multiple alternative TRPs report a list of alternative target UEs and configurable perception parameters based on the perception requirements sent by the SF.

[0444] Step 3: SF selects the common UE as the perception Rx based on the list of candidate target UEs reported by multiple candidate TRPs.

[0445] Step 3a: SF informs all corresponding TRPs of the perception RX.

[0446] Step 4: SF sends multiple TRP perception configuration information and the joint perception range of multiple perception configurations to UE.

[0447] Step 5: The UE can periodically scan and measure multiple sensing configurations and perform collaborative sensing.

[0448] Step 6: When the UE moves beyond the joint sensing range of multiple sensing configurations, the UE reports a sensing link failure, or the network reconfigures the UE.

[0449] The network can inform the terminal via the following signaling: physical layer indication; MAC CE; RRC; direct link between the UE and the sensing control node; through the user plane.

[0450] For an optional implementation of Example 3, please refer to the optional implementation of steps S2301-S2308 in Figure 2C.

[0451] In summary, the above-mentioned scheme proposed in this disclosure allows the network to pre-configure multiple sensing configurations for the UE. The UE switches between sensing configurations according to the configuration conditions or network instructions. The UE can also activate multiple sensing configurations simultaneously to perceive the entire area, reducing the latency caused by terminal mobility when switching sensing configurations.

[0452] In the above embodiments, each step in Figures 2A, 2B, 2C, 3A, and 3B, as well as the different methods in Embodiments 1, 2, and 3, can be executed individually or in combination. For example, step S2111 in Figure 2A and step S2212 in Figure 2B can be executed in combination; step S2201 in Figure 2B and step S2302 in Figure 2C can be executed in combination; step S2111 in Figure 2A and step S3101 in Figure 3A can be executed in combination.

[0453] This disclosure also proposes an apparatus (also referred to as a communication device, etc.) for implementing any of the above methods. For example, an apparatus is proposed that includes units or modules for implementing the steps performed by the terminal in any of the above methods. Furthermore, another apparatus is proposed that includes units or modules for implementing the steps performed by a network device (e.g., an access network device, a core network functional node, a core network device, etc.) in any of the above methods.

[0454] It should be understood that the division of units or modules in the above device is only a logical functional division. In actual implementation, they can be fully or partially integrated into a single physical entity, or they can be physically separated. Furthermore, the units or modules in the device can be implemented by a processor calling software: for example, the device includes a processor connected to a memory containing instructions. The processor calls the instructions stored in the memory to implement any of the above methods or to implement the functions of the units or modules in the above device. The processor can be, for example, a general-purpose processor, such as a Central Processing Unit (CPU) or a microprocessor, and the memory can be internal or external to the device. Alternatively, the units or modules in the device can be implemented in the form of hardware circuits. The functionality of some or all of the units or modules can be achieved through the design of these hardware circuits, which can be understood as one or more processors. For example, in one implementation, the hardware circuit is an application-specific integrated circuit (ASIC). The functionality of some or all of the units or modules is achieved through the design of the logical relationships between the components within the circuit. In another implementation, the hardware circuit can be implemented using a programmable logic device (PLD). Taking a field-programmable gate array (FPGA) as an example, it can include a large number of logic gates. The connection relationships between the logic gates are configured through configuration files, thereby achieving the functionality of some or all of the units or modules. All units or modules of the above device can be implemented entirely through processor-called software, entirely through hardware circuits, or partially through processor-called software with the remaining parts implemented through hardware circuits.

[0455] In this embodiment, the processor is a circuit with signal processing capabilities. In one implementation, the processor can be a circuit with instruction read and execute capabilities, such as a Central Processing Unit (CPU), a microprocessor, a graphics processing unit (GPU) (which can be understood as a microprocessor), or a digital signal processor (DSP). In another implementation, the processor can implement certain functions through the logical relationships of hardware circuits. The logical relationships of the aforementioned hardware circuits are fixed or reconfigurable. For example, the processor is a hardware circuit implemented using an application-specific integrated circuit (ASIC) or a programmable logic device (PLD), such as an FPGA. In a reconfigurable hardware circuit, the process of the processor loading a configuration document and configuring the hardware circuit can be understood as the process of the processor loading instructions to implement the functions of some or all of the above units or modules. Furthermore, it can also be a hardware circuit designed for artificial intelligence, which can be understood as an ASIC, such as a Neural Network Processing Unit (NPU), a Tensor Processing Unit (TPU), or a Deep Learning Processing Unit (DPU).
