AI Technical Summary

Technical Problem

In fifth-generation mobile communication technology, when the user equipment is in the RRC Inactive state, the base station cannot update the beam direction and power configuration of the uplink SRS in a timely manner, resulting in poor reception or inability to receive uplink SRS.

Method used

When the terminal device detects that the signal power is lower than the preset value, it measures the candidate reference signal corresponding to the candidate configuration parameters, determines the candidate reference signal that meets the conditions, and sends its signal parameters to the serving base station to adjust the beam direction and/or power of the uplink SRS.

Benefits of technology

Without switching, it ensures accurate transmission of uplink SRS, improves the base station's reception of uplink SRS, and enables rapid transmission of positioning assistance information.

Abstract

A configuration parameter updating method and device, the method comprising: a terminal in an RRC Inactive state measuring a candidate reference signal corresponding to a candidate configuration parameter when detecting that a first signal power of a first reference signal is less than a preset power; determining a first candidate reference signal that satisfies a preset condition among the candidate reference signals, and sending a signal parameter of the first candidate reference signal to a first serving base station; and adjusting a beam direction and / or transmission power of an uplink SRS according to the first candidate reference signal. Through the method, a terminal in an RRC Inactive state can timely adjust the beam direction of the uplink SRS without switching states, and a base station participating in positioning can also timely adjust the uplink SRS receiving beam according to the signal parameter, thereby realizing positioning of the terminal in the RRC Inactive state.
