AI Technical Summary
In the high-speed rail scenario, two sets of tracking reference signals (TRS) are configured on the same pole, resulting in different locations of TRS time-frequency resources in the same direction, causing mutual interference and reducing demodulation performance. After the TRS resource changes, the base station needs to notify the terminal through RRC or MAC to increase signaling overhead.
By sending the first information including the configuration of the TRS resource, the terminal measures and configures the TRS by itself based on the received information and the maximum number of supported TRS measurements to avoid signaling overhead.
Reduces signaling and resource overhead, improves TRS demodulation performance, and reduces the terminal's dependence on TRS resource configuration.

[0067] In an embodiment of the present application, when the terminal accesses a cell, the network side can send the resource configuration of each TRS of the cell to the terminal. The terminal only needs to measure and track the reference signal according to the received TRS resource configuration and the maximum number of TRSs that the terminal supports to be measured simultaneously. In this way, even when the TRS measurement range changes, the network side does not need to notify the terminal, thereby reducing signaling and resource overhead.

The terminal only needs to measure the tracking reference signal according to the received resource configuration of the TRS and the maximum number of TRSs that the terminal supports to measure simultaneously. In this way, even when the TRS measurement range changes, the network side does not need to notify the terminal, reducing signaling and resource overhead.

[0080] The terminal starts measuring from TRS1 to TRS M If the terminal measures that the signal strength of TRS1 is lower than the threshold TRS , then no longer measure TRS1, start measuring from TRS2 to TRS M+1 , and measure backwards in sequence.
[0081] If the terminal measures TRS as TRS N-M+1 To TRS N , it means that the last M TRSs of this cell have been measured and the measured M TRSs will remain unchanged until switching to a new cell.
