[0156] The fourth type: Base station transmits to terminal receive (i.e., TRP-UE bistatic). The base station transmits a sensing signal, which is reflected by the object being measured, and the terminal receives and measures the reflected / scattered wave.

[0157] The fifth type: Terminal monostatic transmission and reception. The terminal sends a sensing signal, and after the sensing signal passes through the environment or objects in the environment, the terminal receives and measures the reflected / scattered waves.

[0158] The sixth type: Terminal A transmits and Terminal B receives (i.e., UE-UE bistatic). Terminal A transmits a sensing signal, and after the sensing signal passes through the environment or objects in the environment, Terminal B receives and measures the reflected / scattered waves.

[0159] In summary, the above six types can be categorized into two types. The first type is mono-static, where the same node transmits and receives the sensing RS. The second type is bi-static, where different nodes transmit and receive the sensing RS.

[0160] In some embodiments, the sensing target 103 is generally not a network device or terminal and does not have the function of receiving, processing, or transmitting signals. However, the sensing target 103 can reflect / scatter signals after they arrive. The sensing control device 102 needs to determine the position of the target by the signal reflected by the target, or by the changes made by the target in the sensing environment due to its entry into the wireless sensing network (e.g., blocking existing LOS paths between transceivers, blocking existing NLOS paths reflected from known environmental targets to the receiver).

[0161] In some embodiments, commonly used positioning algorithms in sensing systems include DL-TDOA (Down-Like Time Difference of Arrival), UL-TDOA (Up-Like Time Difference of Arrival), multi-RTT (Multi-station Round Trip Time), DL-AOD (Downlink Departure Angle), and UL AOA (Uplink Angle of Arrival). Of these five positioning methods, DL-TDOA requires the receiver to locate itself based on the time difference between the arrival of positioning reference signals transmitted by multiple transmitters, while UL-TDOA requires the transmitter to locate itself based on the time difference between the arrival of positioning reference signals transmitted by multiple receivers. DL-TDOA requires time synchronization among multiple transmitters, and UL-TDOA requires time synchronization among multiple receivers. Multi-RTT, DL-AOD, and UL AOA do not require synchronization between the transmitter and receiver.

[0165] Figure 2 is an interactive schematic diagram of a node information indication method according to an embodiment of the present disclosure. As shown in Figure 2, the embodiments of the present disclosure relate to a node information indication method, which includes:

[0166] Step S2101: The sensing and control device sends a request message to the sensing node.

[0167] In some embodiments, the sensing node receives request information sent by the sensing control device. It should be noted that this embodiment is illustrated by example of the sensing control device sending request information to the sensing node. In another embodiment, the sensing control device may also send request information via broadcast without specifying an object; all sensing nodes within the range of the sensing control device can receive the broadcast request information.

[0168] In some embodiments, the request information is used to request node information of the sensing node. Optionally, the name of the request information in this disclosure embodiment is not limited, and it may be, for example, node acquisition information, node request information, etc.

[0169] In some embodiments, the node information includes the sensing capabilities of the sensing node or auxiliary information of the sensing node. Optionally, the sensing capabilities of the sensing node are used to indicate the capabilities that the sensing node supports during sensing. Optionally, the sensing capabilities can be understood as capability information of the sensing node, or it can be understood as parameters supported by the sensing node during sensing, etc., and this disclosure does not limit this. Optionally, the auxiliary information of the sensing node refers to information of the sensing node affected by external factors, not information affected by factors of the sensing node itself.

[0170] In some embodiments, the sensing node is used to receive and / or transmit sensing signals. Optionally, if the sensing node is both a transmitting node and a receiving node, then the sensing node is used not only to transmit sensing signals but also to receive sensing signals. Optionally, if the sensing node is a transmitting node, then the sensing node is used to transmit sensing signals. Optionally, if the sensing node is a receiving node, then the sensing node is used to receive sensing signals.

[0171] In some embodiments, the sensing signal is used to sense a target. Optionally, the sensing signal is used to acquire the target's speed, shape, position, etc.

[0172] In some embodiments, node information is used by the sensing control device to select a sensing node to sense the target. Optionally, different sensing nodes may have different or the same capabilities and auxiliary information, and therefore, different sensing nodes may transmit or receive sensing signals differently. Thus, the sensing control device can select a sensing node based on the node information of different sensing nodes, so as to match the selected sensing node with the needs of sensing and improve the accuracy of sensing.

[0173] It should be noted that step S2101 in this embodiment is an optional step, and step S2102 can be executed directly without executing step S2101.

[0174] In step S2102, the sensing node sends node information to the sensing control device.

[0175] In some embodiments, the sensing control device receives node information sent by the sensing node. It should be noted that in step S2102 of this embodiment, the sensing node can proactively send its own node information to the sensing control device, or it can feed back its own node information to the sensing control device based on the request information in step S2101. This embodiment does not limit this.

[0176] In some embodiments, the sensing capability of a sensing node or the auxiliary information of the sensing node includes at least one of the following: sensing mode information, self-interference removal capability, the positional accuracy of the sensing node, or the moving speed of the sensing node.

[0177] Optionally, the perception mode information is used to indicate the perception modes supported by the perception node. Optionally, the perception modes include at least one of the following:

[0178] (1) Transceiver mode: Transceiver mode is used to indicate that the sensing node acts as both a sensing signal sending node and a sensing signal receiving node.

[0179] Optionally, if a sensing node acts as both a sensing signal transmitter and receiver, it means that the sensing node transmits and receives sensing signals reflected from the sensing target itself. In this case, the sensing node needs to transmit and receive sensing signals at the same frequency. Optionally, "same frequency" refers to the same frequency.

[0180] It should be noted that if the sensing node supports transmit / receive mode, then the sensing node needs to have the ability to remove interference leakage interference from the same frequency transmission link and the ability to measure multipath signals.

[0181] (2) Transmission mode: The transmission mode is used to indicate that the sensing node is a sensing signal transmitting node.

[0182] (3) Receiving mode, the receiving mode is used to indicate that the sensing node is a sensing signal receiving node.

[0183] In some embodiments, the capabilities or auxiliary information that the sensing node needs to indicate in different sensing modes may differ, and the information carried by the sensing node in the node information it sends may also differ. The information included by the sensing node in the node information in different modes will be described below.

[0184] Optionally, the sensing node supports either a transmit or receive mode, and the node information also includes at least one type of information:

[0185] (1) Maximum transmission bandwidth.

[0186] Optionally, the maximum transmission bandwidth is used to indicate the maximum bandwidth that the sensing node can transmit sensing signals. Alternatively, it can be understood as the maximum bandwidth that the sensing node can use when transmitting sensing signals.

[0187] Optionally, a larger bandwidth for transmitting the sensing signal results in better sensing performance, but also places higher demands on the radio frequency (RF) devices of the sensing node. For example, the RF devices need to ensure phase consistency of the sensing signal within that bandwidth. Phase consistency means that even as the bandwidth of the signal increases, the phase of the signal remains the same at different frequency domain positions.

[0188] (2) First sensing signal waveform.

[0189] Optionally, the sensing signal waveform is used to indicate the signal waveform that the sensing node supports transmitting. For example, the signal waveform includes OFDM (Orthogonal Frequency Division Multiplexing) waveform, OTFS waveform, or pulse waveform, etc., and this disclosure does not limit this.

[0190] (3) First reuse method.

[0191] Optionally, the first multiplexing method is used to indicate the multiplexing method of the sensing signals and communication signals that the sensing node supports transmitting. For example, the multiplexing method includes TDM (Time Division Multiplexing), FDM (Frequency Division Multiplexing), or SDM (Space Division Multiplexing), etc., and this embodiment of the disclosure does not limit this.

[0192] (4) Minimum symbol duration.

[0193] Optionally, the minimum symbol duration is used to indicate the minimum symbol duration of the sensed signal supported by the sensed node. A shorter symbol duration results in better sensing performance, but also places higher demands on the hardware performance of the sensed node. For example, a higher signal processing speed is required to ensure the generated sensed signal reaches the specified symbol duration. Optionally, in the case of OFDM waveforms, there is a one-to-one correspondence between the minimum symbol duration of the sensed signal and the maximum SCS (Subcarrier Spacing) of the sensed signal. The larger the maximum SCS of the OFDM waveform supported by the sensed node, the smaller the minimum symbol duration of the supported sensed signal.

[0194] (5) First protection duration.

[0195] Optionally, the protection duration is used to indicate the duration during which the sensing node switches from transmitting sensing signals to transmitting or receiving communication signals when it is a terminal. For example, if the transmission bandwidth of the sensing signal exceeds the uplink activation bandwidth of the terminal, then when the sensing signal and the communication signal are transmitted in a time-division manner, the terminal needs to adjust the hardware frequency domain parameters for a certain duration (that is, the terminal cannot transmit / receive signals during this first protection duration).

[0196] (6) Antenna aperture.

[0197] Optionally, the antenna aperture includes the elevation antenna aperture and the azimuth antenna aperture. Alternatively, the elevation antenna aperture in this embodiment can be understood as the accuracy of the signal transmission angle at the elevation angle. The azimuth antenna aperture in this embodiment can be understood as the accuracy of the signal transmission angle at the azimuth angle. In some embodiments, the larger the elevation antenna aperture and the azimuth antenna aperture, the higher the signal transmission angle accuracy at the elevation and azimuth angles. Optionally, the antenna aperture in this embodiment can also be a virtual aperture after applying multi-antenna technology to the sensing node.

[0198] (7) Power control capability.

[0199] Optionally, the power control capability is used to indicate whether open-loop power control or closed-loop power control is supported. Optionally, open-loop power control refers to the transmitter determining the transmission power based on empirical values ​​and known environmental information. Optionally, closed-loop power control refers to determining whether to increase or decrease the transmission power, or even change the transmission beam direction, based on the received power measured by the receiver for each path.

[0200] (8) Maximum resources for sending sensing signals.

[0201] Optionally, the maximum resource can be understood as the maximum number of sensing signals to be sent. In this embodiment of the disclosure, limiting the number of sensing signals sent can limit the time-domain resources occupied by the sensing signals. For example, to control the overhead of sensing signals, the resources supported by the reporting node and allocated to sensing services can also be equivalently defined, including the proportion of resources allocated to sensing services and the time periods during which sensing services cannot be allocated.

[0202] In some embodiments, the sensing node supports a receive mode or a transmit / receive mode, and the node information further includes at least one of the following:

[0203] (1) Maximum receiving bandwidth.

[0204] Optionally, the maximum receiving bandwidth is used to indicate the maximum bandwidth of the sensing signal that the sensing node can receive. Optionally, the larger the receiving bandwidth of the sensing signal that the sensing node can support, the better the sensing performance that the node can support, but at the same time, the higher the requirements for the node's radio frequency devices. For example, requiring the sensing node to process the sensing signal within this bandwidth in parallel also generates greater power consumption.

[0205] (2) Waveform of the second sensing signal.

[0206] Optionally, the sensing signal waveform is used to indicate the signal waveform that the sensing node supports receiving. For example, the signal waveform includes OFDM waveform, OTFS (Orthogonal Time Frequency Space) waveform, or pulse waveform, etc., and this disclosure does not limit the specific waveform.

[0207] (3) Second reuse method.

[0208] Optionally, the second multiplexing method is used to indicate the multiplexing method of the sensing signals and communication signals supported by the sensing node. For example, the multiplexing method includes TDM (Time Division Multiplexing), FDM (Frequency Division Multiplexing), or SDM (Space Division Multiplexing), etc., and this embodiment of the disclosure does not limit this.

[0209] (4) Minimum symbol duration,

[0210] Optionally, the minimum symbol duration is used to indicate the minimum symbol duration of the sensing signal supported by the sensing node.

[0211] The shorter the symbol duration of the sensed signal, the better the sensing performance, but the higher the hardware performance requirements of the sensing node. For example, a higher signal processing speed is required to ensure that the generated sensed signal reaches the required symbol duration. Optionally, in the case of OFDM waveforms, there is a one-to-one correspondence between the minimum symbol duration of the sensed signal and the maximum SCS of the sensed signal. The larger the maximum SCS of the OFDM waveform supported by the sensing node, the smaller the minimum symbol duration of the supported sensed signal.

[0212] (5) Second protection duration: The protection duration is used to indicate the duration during which the sensing node switches from receiving sensing signals to transmitting or receiving communication signals when it is a terminal. For example, if the receiving bandwidth of the sensing signal exceeds the uplink activation bandwidth of the terminal, then when the sensing signal and the communication signal are transmitted in a time-division manner, the terminal needs to adjust the hardware frequency domain parameters for a certain duration (that is, the terminal cannot transmit / receive signals during the first protection duration).

[0213] (6) Antenna aperture.

[0214] Optionally, the antenna aperture includes the elevation antenna aperture and the azimuth antenna aperture. Alternatively, the elevation antenna aperture in this embodiment can be understood as the accuracy of the signal transmission angle at the elevation angle. The azimuth antenna aperture in this embodiment can be understood as the accuracy of the signal transmission angle at the azimuth angle. In some embodiments, the larger the elevation antenna aperture and the azimuth antenna aperture, the higher the signal transmission angle accuracy at the elevation and azimuth angles. Optionally, the antenna aperture in this embodiment can also be a virtual aperture after applying multi-antenna technology to the sensing node.

[0215] (7) Power control capability.

[0216] Optionally, the power control capability is used to indicate whether multipath-based closed-loop power control is supported or not. Optionally, the power control capability also includes not supporting power control. Wherein, not supporting power control means that the receiver does not feed back information specifically for instructing the transmitter on power control. Optionally, supporting multipath-based closed-loop power control means that the receiver can measure the received power of each path and send the multipath-related power control information to the network to instruct the sensing signal transmitter to perform multipath-based power control.

[0217] (8) Distinguish the time granularity of multiple paths.

[0218] Optionally, the finer the temporal granularity of multipath discrimination at the receiver, the more multipaths it can distinguish, and thus the more refined the sensing results.

[0219] (9) The maximum number of sensing signals received.

[0220] Optionally, the maximum number includes at least one of the following: the maximum number of sensing signals received from a single transmitting node, the maximum number of multiple sensing signals transmitted from multiple nodes, and the maximum number of nodes from which multiple transmitting nodes receive sensing signals.

[0221] (10) Support resources allocated to receive sensing signals.

[0222] Optionally, the resources that can be allocated to the receiving sensing signal include the proportion of resources allocated to the sensing signal and the time period during which the sensing signal cannot be allocated.

[0223] (11) Supported measurements.

[0224] Optionally, the measured quantities include multipath arrival time, time difference of arrival, angle information, Doppler frequency shift information, etc.

[0225] (12) Supported reporting methods.

[0226] Optionally, the reporting method may include reporting the original channel information, or reporting the calculated time delay, Doppler frequency shift, and angle measurement results for each path.

[0227] In some embodiments, the self-interference cancellation capability includes the interference cancellation capability for leakage interference from co-frequency transmission links and / or the interference cancellation capability for leakage interference from inter-frequency transmission links.

[0228] Optionally, interference cancellation capability for leakage interference from the same-frequency transmission link is required. In transmit / receive mode, the sensing signal transmitted and received by the sensing node are on the same frequency. When the sensing node transmits the sensing signal, leakage interference from the transmission link can interfere with the reception of the sensing signal. The stronger the sensing node's ability to cancel interference from the same-frequency transmission link, the better the sensing node's reception of reflected signals from the target / environment. In some cases, the interference cancellation capability for leakage interference from the same-frequency transmission link can also replace the aforementioned capability of "whether transmit / receive mode is supported": if the sensing node needs transmit / receive mode, it needs to transmit and receive sensing signals on the same frequency. Optionally, a basic requirement for this type of sensing node is that it must have a certain degree of interference cancellation capability for leakage interference from the same-frequency transmission link. When the sensing node's interference cancellation capability for leakage interference from the same-frequency transmission link exceeds a certain threshold, it can be considered that the sensing node has transmit / receive capability.

[0229] Optionally, interference cancellation capability for inter-frequency transmission link leakage: Sensing nodes may need to simultaneously transmit communication signals and receive sensing signals, which reside on different frequency domain resources. When a sensing node transmits communication signals, interference leaked from the transmission link can interfere with the receiving link's reception of sensing signals. The stronger the sensing node's ability to cancel inter-frequency transmission link interference, the smaller the isolation bandwidth required between communication and sensing resources when the sensing node reuses communication and sensing resources.

[0230] In some embodiments, if the sensing node is an access network device, the access network device generally has accurate positioning, such as GPS or BeiDou positioning. If the sensing node is a terminal, the positioning accuracy of the terminal varies when different positioning algorithms are used. Optionally, the terminal or the network device that positions the terminal can send the terminal's positioning accuracy to the sensing control device to help the sensing control device determine and select a suitable terminal as the sensing node.

[0231] In some embodiments, if a single sensing node is used to sense the relative position / velocity information of a target with respect to that single sensing node, it is not necessary for the sensing node to be stationary. For example, a moving vehicle can sense its surroundings using a transmit / receive mode. In some embodiments, if multiple sensing nodes are used for collaborative sensing, the multiple sensing nodes need to be stationary or relatively stationary. For transmit or receive modes, stationary or relatively stationary transmit and receive nodes are more conducive to accurate target sensing due to the involvement of both transmitting and receiving nodes.

[0232] Step S2103: The sensing and control device selects a sensing node based on the node information.

[0233] In this embodiment of the disclosure, the sensing control device selects a suitable node based on the node information and the required QoS requirements of the sensing service, the location and speed of the target being measured, and other factors.

[0234] Optionally, if the sensing service requires high positioning accuracy, the sensing control equipment can select an access network device that supports sending / receiving sensing signals with a large bandwidth and has GPS positioning as the sensing node.

[0235] Alternatively, if the applied sensing algorithm requires measuring angle information, the sensing control device should select a node with the largest possible antenna aperture to accurately measure the angle information.

[0236] Optionally, if the sensing and control device selects a certain node as the sensing node in the transmit / receive mode, it needs to select a node with the capability to remove leakage interference from the same frequency transmission link, and the capability to remove leakage interference from the same frequency transmission link should be as high as possible.

[0237] It should be noted that the above embodiments are examples illustrating how the sensing and control device selects sensing nodes, and the embodiments disclosed herein do not limit the selection method of the sensing and control device.

[0238] Step S2104: The sensing and control device sends configuration information to the sensing node.

[0239] In some embodiments, configuration information is used to configure sensing nodes and / or sensing signals. Optionally, the sensing control device configures the sensing mode of the sensing node using the configuration information. For example, the sensing mode of the sensing node is configured as a transmit / receive mode. Or the sensing mode of the sensing node is configured as a transmit mode. Or the sensing mode of the sensing node is configured as a receive mode.

[0240] The node information indication method involved in the embodiments of this disclosure may include at least one of steps S2101 to S2104. For example, at least one of steps S2101 to S2104 may be implemented as an independent embodiment, but is not limited thereto.

[0241] In some embodiments, at least one of steps S2101-S2104 is optional, and one or more of these steps may be omitted or substituted in different embodiments.

[0242] In some embodiments, other optional implementations described before or after the specification corresponding to FIG2 may be referred to.

[0243] 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.

[0246] 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.

[0247] 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.

[0342] In step S6101, the node reports its relevant information to the network and to the SF so that the SF can select a suitable node as the sensing sending node and sensing receiving node.

[0343] 1. In some embodiments, the node supports the following sensing mode capabilities:

[0344] a) Does it support mono-static sensing mode? If the node needs to support self-transmitting and self-receiving sensing mode, it needs to transmit and receive sensing signals on the same frequency. A basic requirement for this type of node is that it must have a certain degree of interference cancellation capability against leakage interference from the same-frequency transmission link, and the ability to measure multipath signals.

[0345] b) Whether it supports acting as a sender node in bi-static awareness mode or as a transceiver node in mono-static awareness mode. Related to this:

[0346] i. Maximum transmission bandwidth of the sensing signal. Generally, the larger the transmission bandwidth of the sensing signal, the better the sensing performance. However, this also places higher demands on the radio frequency (RF) devices of the node. For example, the RF devices need to ensure the phase consistency of the sensing signal within this bandwidth, which also results in greater power consumption.

[0347] ii. Supported sensing signal waveforms. For example, OFDM waveforms, OTFS waveforms, or pulse waveforms are supported.

[0348] iii. Supported multiplexing methods for sensing and communication signals. For example, supporting resource multiplexing of sensing and communication signals using TDM (Time Division Multiplexing), FDM (Frequency Division Multiplexing), or SDM (Space Division Multiplexing).

[0349] iv. Minimum symbol duration of the sensed signal. Generally, the shorter the symbol duration of the sensed signal, the better the sensing performance, but the higher the hardware performance requirements of the node, such as requiring a higher signal processing speed to ensure that the generated sensed signal reaches the required symbol duration. In the case of OFDM waveforms, there is a one-to-one correspondence between the minimum symbol duration of the sensed signal and the maximum SCS of the sensed signal. The larger the maximum SCS of the OFDM waveform supported by the node, the smaller the minimum symbol duration of the supported sensed signal.

[0350] v. If the node is a UE: If the sensing signal transmission bandwidth exceeds the UE's uplink activation bandwidth, then when the sensing signal is transmitted and the communication signal is transmitted in a time-division manner, the UE needs to adjust the hardware frequency domain parameters for the guard period (i.e., the UE cannot transmit / receive signals during this period).

[0351] vi. Antenna aperture at elevation and azimuth angles, or equivalently, signal transmission angle accuracy at elevation and azimuth angles. Generally, the larger the virtual antenna aperture at elevation and azimuth angles, the higher the signal transmission angle accuracy at elevation and azimuth angles. The antenna aperture can also be a virtual aperture obtained by applying multi-antenna technology to the node.

[0352] vii. Power control support capability. This includes support for open-loop power control, which refers to the transmitting end determining the transmission power based on empirical values ​​and known environmental information; and support for multipath-based closed-loop power control, which refers to determining whether to increase or decrease the transmission power, or even change the transmission beam direction, based on the received power measured at each path by the receiving end.

[0353] viii. Maximum resources for sending sensing signals. For example, the maximum number of sensing signals that can be sent. Limiting the number of sensing signals sent can limit the time-domain resources occupied by the sensing signals. To control the overhead of sensing signals, the resources allocated to sensing services supported by the reporting node can also be equivalently reported, including the proportion of resources allocated to sensing services and the time periods during which sensing services cannot be allocated.

[0354] c) Whether it supports acting as a receiver node in bi-static sensing mode or as a transceiver node in mono-static sensing mode. Related to this:

[0355] i. Maximum receiving bandwidth of the sensed signal. Generally, the larger the receiving bandwidth of the sensed signal that the node can support, the better the sensing performance that the node can support. However, at the same time, the requirements for the node's radio frequency devices are higher. For example, the node is required to process the signals within this bandwidth in parallel, which also generates greater power consumption.

[0356] ii. Supports received sensing signal waveforms. For example, it supports OFDM waveforms, OTFS waveforms, or pulse waveforms.

[0357] iii. Supports multiplexing methods for received sensing signals and communication signals. For example, it supports resource multiplexing of sensing signals and communication signals using TDM (Time Division Multiplexing), FDM (Frequency Division Multiplexing), or SDM (Space Division Multiplexing).

[0358] iv. Minimum symbol duration supported for processing sensed signals. Generally, the shorter the symbol duration of the sensed signals that a node can support, the better the sensing performance of the node, but the higher the hardware performance requirements of the node, such as requiring a higher signal processing speed to accurately process the received sensed signals. In the case of OFDM waveforms, there is a one-to-one correspondence between the minimum symbol duration of the sensed signal and the maximum SCS of the sensed signal. The larger the maximum SCS of the OFDM waveform supported by the node, the smaller the minimum symbol duration of the sensed signal it supports.

[0359] v. If the node is a UE: If the sensing signal receiving bandwidth exceeds the UE's uplink activation bandwidth, then when receiving sensing signals and transmitting and receiving communication signals are time-division multiplexed, the UE will adjust the guard period required to adjust the hardware frequency domain parameters. That is, the UE cannot transmit / receive signals during this period.

[0360] vi. Elevation and azimuth virtual antenna apertures, or equivalently, the accuracy of signal reception at the elevation angle and the accuracy of signal reception at the azimuth angle. Generally, the larger the elevation and azimuth virtual antenna apertures, the higher the accuracy of the receiver in determining the elevation and azimuth angles of the received signal.

[0361] vii. Power control support capability. This includes: no power control support (meaning the receiver does not provide feedback information specifically for instructing the transmitter on power control); and support for multipath-based closed-loop power control (meaning the receiver can measure the received power of each path and send the corresponding power control information to the network, instructing the sensing signal transmitter to perform power control based on the multipath).

[0362] viii. Temporal granularity for multipath discrimination. The finer the temporal granularity for multipath discrimination at the receiver, the more multipath paths it can distinguish, and thus the more refined the sensing results.

[0363] ix. Maximum number of received sensing signals. This includes the maximum number of sensing signals received from a single transmitting node, the maximum number of multiple sensing signals transmitted from multiple nodes, and the maximum number of nodes from which multiple transmitting nodes can receive sensing signals.

[0364] x. The resources that the node supports for allocating to receiving sensing services, including the proportion of resources allocated to sensing services and the time periods during which sensing services cannot be allocated.

[0365] xi. The measurements supported by the receiving node include multipath arrival time, time difference of arrival, angle information, Doppler frequency shift information, etc. If SF wants to use a specific sensing and positioning method, the receiving node needs to have the ability to support the measurements required by that sensing and positioning method. For example, if the positioning method that SF wants to use requires sensing the angle information of the target's related paths, then the receiving node needs to have the ability to measure the angle information in the multipath.

[0366] xii. The information reporting methods supported by the node. For example, whether to report the raw channel information, or to report the calculated delay, Doppler shift, and angle measurement results for each path.

[0367] 2. Self-interference deletion capability. This can include two capabilities:

[0368] a) Interference removal capability against co-frequency transmission link leakage interference. In mono-static mode, the sensing signals transmitted and received by a node are on the same frequency. Interference leaked from the transmission link during signal transmission can interfere with the received sensing signals. The stronger the node's ability to remove co-frequency transmission link interference, the better the node's reception of reflected signals from target / environment reflections. In some cases, this capability can also replace the aforementioned capability of "whether it supports self-transmitting and self-receiving sensing mode": if a node needs to support self-transmitting and self-receiving sensing mode, it needs to transmit and receive sensing signals on the same frequency again. A basic requirement for this type of node is that it must have a certain degree of interference removal capability against co-frequency transmission link leakage interference. When a node's interference removal capability against co-frequency transmission link leakage interference exceeds a certain threshold, it can be considered that the node has the capability to support self-transmitting and self-receiving sensing mode.

[0369] b) Interference removal capability against inter-frequency transmission link leakage. Nodes may need to simultaneously transmit communication signals and receive sensing signals, which reside on different frequency domain resources. Interference leaked from the transmission link when a node transmits signals can interfere with the reception of sensing signals. The stronger a node's ability to remove inter-frequency transmission link interference, the smaller the isolation bandwidth required between communication and sensing resources when the sensing node reuses communication and sensing resources.

[0370] 3. Node Location Information Accuracy. Since many sensing and positioning methods rely on the location information of the sending and receiving nodes to determine the target's location, the accuracy of these nodes' locations is a crucial factor affecting sensing performance. If the node is a base station, it typically possesses precise positioning capabilities, such as GPS or BeiDou. If the node is a UE (User Equipment), the positioning accuracy can vary depending on the positioning algorithm used. The UE or the network locating it can report the UE's positioning accuracy to the SF (Sensing Controller) to help the SF select a suitable UE as a sensing node.

[0371] 4. Node movement speed, or whether the node is stationary. In mono-static mode, if a single station is used to sense the relative position / velocity of a target with respect to that single station, the node does not need to be stationary. For example, a moving vehicle can sense its surroundings using mono-static sensing mode. If multiple stations are used for collaborative sensing, then all stations need to be stationary or relatively stationary. In bi-static mode, because it involves transmitting and receiving node pairs, stationary or relatively stationary node pairs are more conducive to accurate target sensing.

[0372] For example, after receiving the capabilities / information of a node, the SF can select a suitable node based on that capability / information, the required QoS requirements of the sensing service, the location and speed of the target being measured, and other factors. For instance, if the sensing service requires high positioning accuracy, the SF can select a base station that supports transmitting / receiving a large bandwidth Sensing RS and has GPS positioning as the sensing node. If the applied sensing algorithm requires measuring angle information, the SF should select a sensing node with the largest possible antenna aperture to accurately measure the angle information. If the SF selects a node as a monostatic sensing node, it needs to select a node with the highest possible level of co-frequency transmission link leakage interference cancellation capability.

[0373] 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.
