An embodiment of the present invention provides a UE positioning method, as shown in fig. 1, the method includes:
step 101, a base station receives a random access preamble message sent by a UE on PRACH resources.
Wherein, the PRACH resource corresponds to SSB of the cell to which the UE belongs.

It should be further noted that, since the PRACH resource corresponds to the SSB of the UE home cell, the base station receives the random access Preamble message sent by the UE on the PRACH resource, that is, the random access Preamble message is sent by the UE on the PRACH resource corresponding to the SSB of the home cell.
Optionally, before the base station receives the random access preamble message sent by the UE on the PRACH resource, the method further includes:
and the base station configures SSBs for all the cells in the virtual cell.

In one illustrative example, step 102 comprises:
and the base station acquires the SSB corresponding to the PRACH resource of the random access preamble message sent by the UE from the corresponding relation of the PRACH resource and the SSB.
And the base station acquires the cell corresponding to the obtained SSB in the corresponding relation between the SSB and the cell in the virtual cell as the home cell of the UE in the virtual cell.
In an exemplary embodiment, when the number of cells is greater than the configurable number of SSBs, the base station configures SSBs for all cells in the virtual cell, including:
and the base station configures SSBs for all the cells in the virtual cell in a mode of multiplexing the SSBs.
Specifically, when the interference isolation between two or more cells in the virtual cell satisfies a certain condition, the cells may be configured with the same SSB. The interference isolation degree meeting a certain condition may specifically mean that the distance is greater than a preset distance, and the preset distance may be a distance at which the signal interference caused by itself to the other party is less than a preset interference value.

The embodiment of the invention also provides a UE positioning method, which comprises the following steps:
step 1, configuring different SSBs for N transmission points belonging to a virtual cell, and configuring PRACH resources corresponding to each SSB, where in a 5G protocol, the number of configurable SSBs supported by different frequency bands is different, and it can be supported to configure 64 SSBs at maximum, where N is the number of transmission points included in a virtual cell, and if the value of N is greater than the number of configurable SSBs, SSBs can be multiplexed, and a specific multiplexing method may be: as long as the interference isolation between the sending points meets a certain condition, the two sending points may configure the same SSB, where the PRACH resource configuration requires that the time domain, the frequency domain, or the code domain corresponding to the PRACH resources corresponding to different SSBs are different.
And step 2, the UE detects the SSB and sends an access Preamble message on the PRACH resource corresponding to the detected SSB.
And step 3, the base station determines the SSB corresponding to the UE according to the Preamble resource sent by the UE, thereby determining a sending point corresponding to the SSB, wherein the sending point is the sending point to which the UE belongs.
