This application claims the priority of Chinese Patent Application No. 202010413028.3 filed in China on May 15, 2020, the entire content of which is incorporated herein by reference.

Technical field

The present disclosure relates to the field of communication technology, and in particular to a method, device and equipment for sending and receiving information.

Background technique

Among the positioning methods in related technologies, the Multi-RTT (Multiple-Round Trip Time) positioning method is an important positioning method, and the measurement used in the Multi-RTT positioning method is UE (User Equipment, The arrival time of DL-PRS (Downlink Positioning Reference Signal) measured by the user equipment or terminal) from each TRP (Transmit and Receive Point) and the SRS-Pos (Sounding Reference Signal) sent by the UE for Positionling, the time difference between the sounding reference signal used for positioning (called the UE receiving and sending time difference) and the time difference between the arrival time of the SRS-Pos measured by each TRP and the TRP sending DL-PRS (called the gNB receiving and sending Time difference).

The working principle of the Multi-RTT positioning method is: the UE reports the obtained UE receiving and sending time difference to the LMF (Location Management Function), and each TRP also provides the obtained gNB receiving and sending time difference to the LMF, and the LMF uses the UE receiving and sending time difference The difference between the sending and receiving time and the gNB is the distance between the UE and each TRP. Then add other known information (such as the geographic coordinates of the TRP) to calculate the location of the UE.

As mentioned above, for the Multi-RTT positioning method, in order to complete the measurement of the UE receiving and sending time difference or the gNB receiving and sending time difference, the TRP needs to send DL-PRS and the UE sends SRS-Pos, and then the UE or gNB can be based on DL-PRS and SRS-Pos. Complete the measurement of related measurement quantities.

In related protocols, a pair of DL-PRS and SRS-Pos used to calculate the measurement of the difference in the transmission and reception of the UE or the measurement of the difference in the transmission and reception of the gNB may be sent in different frequency bands.

Take the time difference between the sending and receiving of the UE as an example. If TRP sends DL-PRS in the first frequency band (band 1) and the UE sends SRS-Pos in the second frequency band (band 2), then the UE will transfer the DL-PRS in the first frequency band. It is paired with the SRS-Pos in the second frequency band to calculate the difference between the UE transmission and reception time. In this way, the first frequency band and the second frequency band belong to different timing advance groups (TAG), resulting in the DL-PRS on the first frequency band and the second frequency band. The SRS-Pos on the second frequency band adjusts the sending time based on different TAGs, and the final calculated UE receiving and sending time difference will be inaccurate, thereby affecting the final positioning accuracy.
