For convenience of description, the "cell information" or "the cell information" in the embodiments of the present invention refers to cell information of a serving cell and a neighboring cell.
The first measurement result is obtained by the terminal measuring the serving cell and the neighboring cell based on the cell information of the serving cell and the neighboring cell.
Specifically, the first measurement result may include a result obtained by the terminal performing measurement on the serving cell and the neighboring cell based on the spatial relationship signal in the cell information, or may include a result obtained by the terminal performing measurement on the serving cell and the neighboring cell based on the power configuration information in the cell information.
In the embodiment of the invention, the terminal is configured with the cell information of the serving cell and the adjacent cell, so that the terminal can set the SRS transmission parameters according to the cell information of the serving cell and the adjacent cell and/or the measurement results of the serving cell and the adjacent cell. The terminal comprehensively considers the cell information of the serving cell and the adjacent cell in the setting of the SRS transmission parameters, so that the directivity, the positioning property and the coverage property of SRS transmission are improved.
In this embodiment of the present invention, there are various ways for the network side device to configure the cell information for the terminal, that is, step 201 may include:
a serving cell configures cell information of a neighboring cell for the terminal through a Radio Resource Control (RRC) message; alternatively, the first and second liquid crystal display panels may be,
the server configures the cell information for the terminal through an LPP (LTE Positioning Protocol) signaling or an LPP evolution signaling or a data channel.
Therefore, in the embodiment of the present invention, the network side device configures the cell information for the terminal, which can be implemented by the serving cell or the server.
And the serving cell configures cell information of the adjacent cell for the terminal through RRC message.
It should be noted that before the serving cell configures the cell information of the neighboring cell for the terminal, the terminal may already acquire the cell information of the serving cell itself. Therefore, when the serving cell configures the cell information for the terminal, only the cell information of the neighboring cell may be configured. Of course, the serving cell may also configure cell information of the serving cell itself and cell information of neighboring cells for the terminal at the same time.
In the following, different cell information content allocation schemes will be described for embodiments in which the serving cell allocates the cell information of the neighboring cells to the terminal.

It should be noted that, the indication identifier of the non-serving cell and the spatial relationship configuration information of the non-serving cell are directly configured, and it can be understood that the original serving cell identifier and the spatial relationship configuration information of the original serving cell are reserved in the spatial relationship configuration information of the SRS, and the indication identifier of the non-serving cell and the spatial relationship configuration information of the non-serving cell are added.
In a certain aspect, the indication identifier of the non-serving cell and the spatial relationship configuration information of the non-serving cell are directly added to the spatial relationship configuration information of the SRS, and compared with the method for changing the original serving cell identifier, the method has the advantage of being easy to implement.
In this embodiment, DL-PRS information of the neighboring cell may also be configured in the spatial relationship configuration information of the SRS, and the DL-PRS information may include at least one of DL-PRS resource set ID and DL-PRS resource ID.
Optionally, the power configuration information of the neighboring cell includes a path loss reference signal configuration of the SRS; alternatively, the first and second electrodes may be,

The DL-PRS information may include at least one of a DL-PRS resource set ID and a DL-PRS resource ID.
In this embodiment, other neighboring cells may also be introduced in the CGs (i.e., the primary cell and the primary and secondary cell groups) of the measureObject to implement configuring the power configuration information of the neighboring cells for the terminal.
In this embodiment, reference signal information and transmission power information of the reference signal may also be introduced in the measureObject to implement configuring the power configuration information of the neighboring cell for the terminal. Wherein, the reference signal can include SSB and DL-PRS, the reference signal information can include cell ID to which the reference signal belongs and TRP ID of the reference signal, and the transmission power information of the reference signal can include at least one of transmission power of the serving cell SSB, offset of the transmission power of the neighbor cell SSB relative to the transmission power of the serving cell SSB, transmission power of the serving cell DL-PRS, and offset of the transmission power of the neighbor cell DL-PRS relative to the transmission power of the serving cell SSB.
Specifically, the DL-PRS transmission power of the serving cell and/or the offset configuration of the neighboring cells with respect to the serving cell SSB power and the signal configuration of the DL-PRS may be introduced in the measureObject. For example, a DL-PRS measurement configuration IE is added, including at least a DL-PRS set, a DL-PRS resource set, and corresponding DL-PRS signal configuration information and transmit power.

The first method is as follows: if the conflicting information is the information of the serving cell or the information of the primary and secondary cells, the terminal may perform the relevant setting of the SRS transmission parameters with the information configured by the serving cell as the high priority, or may select one of the configurations or select another configuration according to the measurement condition, and report the updated QCL indication information and the measurement result.
The second method comprises the following steps: if the conflicting information is spatial relationship information of the neighboring cell, the terminal may select one of the configurations according to the measurement condition or select another configuration according to the measurement condition, and report updated QCL indication information and measurement results, and if the conflicting information is power configuration information of the neighboring cell and configuration information of the specific signal, the terminal may perform related setting of SRS transmission parameters with high priority based on the configuration of the server.
The two modes provide a conflict solution for the terminal, so that the terminal can reasonably select the SRS transmission scheme under the conflict configuration.

Specifically, the serving cell acquires cell information of the neighboring cell from the location server through LPPA signaling, NRPPA signaling, or a data channel.
