[0119] New Radio (NR) can support higher data rates and lower latency. NR frequency bands include FR1 and FR2. In the prior art, for the FR2 downlink scenario, the Transmission Configuration Indicator (TCI) state is used to notify the terminal of the recommendation for the receiving beam. Each TCI state indicates a reference signal of the spatial receiving parameter QCL type D (QCL-D) with respect to the reference signal to be received. The terminal uses the receiving beam of the reference signal QCL original signal as the receiving beam recommended by the base station.

[0120] For the FR2 uplink scenario, spatial relation information (spatial relation info) is used to notify the terminal of the recommendation for the transmission beam. The reference signal (RS) in the spatial relation information may include a synchronization signal block (SSB) index (ssb-Index), a channel state information reference signal (CSI-RS) index (CSI-RS-Index), or a sounding reference signal (SRS). Among them, if the reference signal in the spatial relationship information includes 'ssb-Index', the terminal uses the same spatial domain used to receive SSB for uplink transmission, such as transmitting SRS and physical uplink control channel (PUCCH); if the reference signal in the spatial relationship information includes 'CSI-RS-Index', the terminal uses the target SRS resource in the same spatial domain used to receive periodic CSI-RS or semi-persistent CSI-RS for uplink transmission; if the reference signal in the spatial relationship information includes "SRS", the terminal should use the same spatial domain used to transmit periodic SRS or semi-persistent SRS for uplink transmission.

[0121] The collaborative sensing mode of integrated communication and perception refers to a working mode in which at least two nodes collaboratively sense the same target. The working modes of integrated communication and perception include independent sensing mode and collaborative sensing mode. Among them, in the collaborative sensing mode, a sensing node (sensing subject) is used to send a sensing signal (also called a sensing reference signal), and the sensing signal is transmitted to the collaborative sensing node (collaborative subject) after being reflected by the sensing target. The collaborative sensing node determines the position and / or speed of the sensing target and other information based on the sensing signal. Among them, the sensing subject and the collaborative subject can be a base station and a terminal respectively; the sensing signal carrying the information of the sensing target may be transmitted to the collaborative sensing node via the NLOS path.

[0122] In order for the cooperative sensing node to determine the location and / or speed of the sensing target based on the measurement results of the NLOS path of the sensing signal, the base station and the terminal need to have a consistent understanding of the following aspects:

[0123] 1. When the base station sends a perception signal and the terminal receives the perception signal transmitted via the NLOS path, before the base station sends the perception signal, the base station should inform the terminal of the spatial filtering characteristics between the perception signal and reference signals such as SSB / CSI-RS, so that the terminal knows which NLOS receiving beam corresponding to which SSB / CSI-RS is used to receive the perception signal;

[0124] 2. When the terminal sends a perception signal and the base station receives the perception signal transmitted via the NLOS path, before the terminal sends the perception signal, the base station should inform the terminal of the spatial filtering characteristics between the perception signal and reference signals such as SSB / CSI-RS / SRS, so that the terminal knows which SSB / CSI-RS corresponds to which NLOS receiving beam and which corresponding transmitting beam to use to send the perception signal.

[0125] However, in the related art, the base station will not inform the terminal of the spatial filtering characteristics between the perception signal and the NLOS and / or LOS path of the SSB / CSI-RS, resulting in the terminal being unable to use a suitable receiving beam to receive the perception signal sent by the base station, or the terminal being unable to use a suitable transmitting beam to transmit the perception signal, or the quality of the perception signal received by the terminal or the base station being poor, or the perception signal received by the terminal or the base station not containing the perception target information, resulting in low accuracy of the perception information of the perception target determined based on the received perception signal.

[0126] Based on this, in various embodiments of the present application, the network device sends the first information and / or the second information to the terminal; the terminal receives the first information and / or the second information sent by the network device; wherein the first information is at least used to indicate the spatial receiving parameter information of the NLOS path and / or the LOS path of the perception signal; the second information is at least used to indicate the spatial transmitting parameter information of the perception signal. In the above scheme, the network device sends the first information and / or the second information to the terminal, which enables the terminal to use a suitable receiving beam to receive the perception signal according to the first information to perform target perception, thereby improving the perception accuracy of the terminal; it also enables the terminal to use a suitable transmitting beam to send the perception signal according to the second information, so that the network side receives the perception signal accordingly to perform target perception, thereby improving the perception accuracy of the network device.

[0127] The present application is further described in detail below in conjunction with the accompanying drawings and embodiments.

[0128] The present application embodiment provides a parameter configuration method, which is applied to a network device, wherein the network device includes a base station. Figure 1 As shown, the method includes:

[0129] Step 101: Sending the first information and / or the second information to the terminal.

[0130] The first information is at least used to indicate the spatial reception parameter information of the NLOS path and / or LOS path of the perception signal; and the second information is at least used to indicate the spatial transmission parameter information of the perception signal.

[0131] Here, in a scenario where the network device and the terminal work in a collaborative perception mode and the network device sends a perception signal, the network device sends a first information to the terminal so that the terminal can receive the perception signal according to the first information to perform target perception according to the perception signal. Among them, the perception signal received by the terminal may be a perception signal after being reflected by the perception target, and the perception signal after being reflected by the perception target may also be called an echo signal. The network device may indicate the spatial reception parameter information of the NLOS path of the perception signal by indicating the NLOS path of the reference signal; and indicate the spatial reception parameter information of the LOS path of the perception signal by indicating the LOS path of the reference signal. For example, in the case where the first information indicates the NLOS path of the reference signal, the terminal uses the spatial reception parameter information of the NLOS path of the reference signal indicated by the first information, and receives the perception signal sent by the network device in the receiving direction of the NLOS path of the reference signal indicated by the first information. At this time, the received perception signal is generally transmitted via the NLOS path of the perception signal. For another example, when the first information indicates the LOS path of the reference signal, the terminal uses the spatial reception parameter information of the LOS path of the reference signal indicated by the first information, and receives the perception signal sent by the network device in the receiving direction of the LOS path of the reference signal indicated by the first information. At this time, the received perception signal is generally transmitted via the LOS path of the perception signal.

[0132] In a scenario where the network device and the terminal work in a cooperative sensing mode and the terminal sends a sensing signal, the network device sends second information to the terminal so that the terminal can send a sensing signal according to the second information, and the network device receives the sensing signal according to the second information to sense the target according to the sensing signal. The sensing signal received by the network device may be a sensing signal after being reflected by the sensing target. In the case where the second information indicates the NLOS path of the reference signal, the terminal uses the spatial transmission parameter information of the NLOS path of the reference signal indicated by the second information to transmit the sensing signal in the transmission direction of the NLOS path of the reference signal indicated by the second information, and the network device receives the sensing signal in the receiving direction of the NLOS path of the reference signal according to the second information. At this time, the received sensing signal is generally a sensing signal transmitted via the NLOS path of the sensing signal; in the case where the second information indicates the LOS path of the reference signal, the terminal uses the spatial transmission parameter information of the LOS path of the reference signal indicated by the second information to transmit the sensing signal in the transmission direction of the LOS path of the reference signal indicated by the second information, and the network device receives the sensing signal in the receiving direction of the LOS path of the reference signal according to the second information. At this time, the received sensing signal is generally a sensing signal transmitted via the LOS path of the sensing signal. The receiving direction and transmitting direction of the same NLOS path can be the same, and the receiving direction and transmitting direction of the same LOS path can be the same. The receiving direction of the NLOS path and the receiving direction of the LOS path are related to the receiving direction of the beam. The transmitting direction of the NLOS path and the transmitting direction of the LOS path are related to the transmitting direction of the beam.

[0133] It should be noted that the first information can be understood as TCI state information, or spatial reception parameter information. The first information may include relevant information of the reference signal, the spatial reception parameter of the NLOS path of the reference signal is the same as the spatial reception parameter of the NLOS path of the perception signal, and / or, the spatial reception parameter of the LOS path of the reference signal is the same as the spatial reception parameter of the LOS path of the perception signal; the spatial reception parameter may include at least one of the location information of the receiving beam, antenna port and time-frequency resources. The second information may be understood as spatial relationship information, such as SeRS-spatialrelationinfo, TCI uplink state (TCI-UL-State) information, TCI state information, or spatial transmission parameter information. The second information may include relevant information of the reference signal, the spatial transmission parameter of the NLOS path of the reference signal is the same as the spatial transmission parameter of the perception signal, and / or, the spatial transmission parameter of the LOS path of the reference signal is the same as the spatial transmission parameter of the perception signal; the spatial transmission parameter may include at least one of the location information of the transmitting beam, antenna port and time-frequency resources. Among them, a reference signal has at least one NLOS path, and a reference signal has only one LOS path. A sensing signal has at least one NLOS path, and a sensing signal has only one LOS path.

[0134] In order to facilitate the terminal to determine the spatial reception parameter information of the NLOS path and / or the LOS path of the perception signal, so that the terminal can accurately receive the perception signal to improve the perception accuracy of the terminal, in one embodiment, the first information includes at least one of the following:

[0143] When the network device is configured with a repeatedly transmitted perception signal, the first information also includes third information. The repeatedly transmitted perception signal can be understood as a periodic or semi-persistent perception signal, and the third information can be used to indicate spatial reception parameter information of the repeatedly transmitted perception signal.

[0144] In one embodiment, when the first information includes the first identifier and the first indication, the first QCL type is used to indicate that the NLOS path of the perception signal and the reference signal corresponding to the first identifier have the same spatial reception parameter; or

[0146] In the case where the first information includes a first identifier and a second indication, the first QCL type is used to indicate that the perception signal and the LOS path of the reference signal corresponding to the first identifier have the same spatial reception parameters.

[0148] In an embodiment of the present application, multiple parameters may be used to jointly indicate the spatial reception parameter information of the NLOS path and / or LOS path of the perception signal, so that the terminal can quickly and accurately determine the spatial reception parameter information of the NLOS path and / or LOS path of the perception signal.

[0203] Here, when the first information includes the first identifier, the first indication, and the first QCL type, the terminal may receive the perception signal using the spatial reception parameters of the NLOS path with the strongest signal quality of the reference signal corresponding to the first identifier. That is, the perception signal sent by the network device is transmitted to the terminal through the NLOS path with the strongest signal quality of the reference signal corresponding to the first identifier.

[0204] In the case where the first information includes the first identifier, the second identifier, and the first QCL type, the terminal uses the spatial reception parameter of the first NLOS path of the reference signal corresponding to the first identifier to receive the perception signal in the reception direction of the first NLOS path of the reference signal.

Among them, the spatial transmission parameter information of the NLOS path and / or the LOS path of the reference signal can be sent by the network device to the terminal, and can also be measured by the terminal and stored in the terminal.

[0228] In the case where the second information includes the seventh indication, if the first information includes the third identifier and the fourth identifier, the terminal can reuse the NLOS path corresponding to the fourth identifier of the reference signal corresponding to the third identifier to calculate the path loss, and use the path loss to determine the transmit power of the perception signal; if the first information includes the third identifier and the fifth indication, the terminal can reuse the NLOS path with the highest signal quality of the reference signal corresponding to the third identifier to calculate the path loss, and use the path loss to determine the transmit power of the perception signal; if the first information includes the third identifier and the sixth indication, the terminal reuses the LOS path of the reference signal corresponding to the third identifier to calculate the path loss, and uses the path loss to determine the transmit power of the perception signal.

[0253] Step 1: The network device sends the measurement configuration to the terminal.

[0254] The measurement configuration represents the measurement configuration of the NLOS path and / or the LOS path of the reference signal. The number of the terminals may be one or at least two.

The spatial reception parameter may include relevant information of the receiving beam and / or the time-frequency resources used to transmit the reference signal.

[0257] For example, in the case where the measurement configuration represents a measurement configuration of an NLOS path with respect to a reference signal, Figure 4 As shown, the terminal measures and obtains the spatial reception parameters corresponding to the NLOS1 path (NLOS ID = 1) of SSB2, the spatial reception parameters corresponding to the NLOS2 path (NLOS ID = 2) of SSB2, the measurement results of the NLOS1 path of SSB2, and the measurement results of the NLOS2 path of SSB2.

[0280] Step 5: The terminal receives the perception signal sent by the network device according to the first information.

[0281] Here, the network device uses the spatial transmission parameters of the reference signal to send the perception signal; the terminal receives the perception signal according to the first information.

The network device can determine the correspondence between the perception target and the NLOS path of the reference signal based on the measurement results of the NLOS path of the reference signal reported by the terminal within a period of time, for example, there is a correspondence between the perception target and the NLOS2 path of SSB2; according to the correspondence between the perception target and the NLOS path of the reference signal, send the first information to the terminal, and use the spatial transmission parameters of the reference signal to send the perception signal, the first information is used to indicate the spatial reception parameter information of the NLOS path of the perception signal. The terminal receives the perception signal according to the first information, and perceives according to the received perception signal. When the network device receives the measurement result of the NLOS1 path of SSB2 and the measurement result of the NLOS2 path of SSB2, since the perception target has a corresponding relationship with the NLOS2 path of SSB2, the network device configures the NLOS2 of SSB2 as the reference NLOS path of the reference signal in the first information, and uses the spatial transmission parameters of SSB2 to send the perception signal, and the terminal receives the perception signal in the receiving direction of the NLOS2 path of SSB2; the first information may include a first identifier (SSB2), a second identifier (NLOS2) and a first QCL type, and the first QCL type may be QCL-E.

[0302] In one embodiment, the fourth information further includes at least one of the following:

[0304] An index or an identifier or an index list or an identifier list of a reference signal corresponding to the repeatedly transmitted perception signal;

[0307] A NLOS path list or a LOS path list of reference signals corresponding to the repeatedly transmitted sensing signals;

[0308] The index or identifier or index list or identifier list of the NLOS path of the reference signal corresponding to the repeatedly transmitted perception signal.

[0309] Step 5: The terminal sends a perception signal according to the second information.

[0310] Here, for the implementation process of the terminal sending the perception signal according to the second information, please refer to the relevant description above and will not be repeated here.

[0311] It should be noted that, in actual application, the measurement configuration sent by the network device represents the measurement configuration of the NLOS path of the reference signal; the terminal determines the spatial reception parameters of the NLOS path of the reference signal according to the measurement configuration, and then obtains the spatial transmission parameters of the NLOS path of the reference signal, and measures the measurement results of the NLOS path of the reference signal, and reports the measurement results of the NLOS path of the reference signal that meet the reporting conditions to the network device, for example, the terminal reports the measurement results of the NLOS1 path of SSB2 and the measurement results of the NLOS2 path of SSB2 to the network device. The network device can determine the correspondence between the perception target and the NLOS path of the reference signal according to the measurement results of the NLOS path of the reference signal reported by the terminal within a period of time; according to the correspondence between the perception target and the NLOS path of the reference signal, send the second information to the terminal, and the second information is used to indicate the spatial transmission parameter information of the perception signal. The terminal sends a perception signal according to the second information, and the network device uses the spatial reception information of the NLOS path of the reference signal to receive the perception signal and perceive according to the perception signal. Among them, when the network device receives the measurement result of the NLOS1 path of SSB2 and the measurement result of the NLOS2 path of SSB2, since the perception target has a corresponding relationship with the NLOS2 path of SSB2, the network device determines the second information according to the spatial transmission parameters of the NLOS2 path of SSB2, and uses the spatial reception information of the NLOS2 path of SSB2 to receive the perception signal; the second information may include a third identifier (SSB2), a fourth identifier (NLOS2) and a second QCL type, and the second QCL type may be QCL-E. The terminal may use the spatial transmission parameters of the NLOS2 path of SSB2 to send the perception signal, and the network device uses the spatial reception parameters of the NLOS2 path of SSB2 to receive the perception signal.

[0312] It should be noted that in a scenario where there are multiple perception targets, the network device can, based on the correspondence between the perception target and the NLOS path / LOS path of the reference signal, send down different spatial reception parameters and spatial transmission parameters of the NLOS path / LOS path of the reference signal for different perception targets, so as to improve the perception accuracy for different perception targets.
