Title:
METHOD AND DEVICE FOR STARTING AND STOPPING TRANSMISSION OF INACTIVE SOUNDING REFERENCE SIGNAL IN WIRELESS MOBILE COMMUNICATION SYSTEM
Document Type and Number:
WIPO Patent Application WO/2023/058952
Kind Code:
A1
Abstract:
A terminal method according to one embodiment of the present disclosure may comprise the steps of: transmitting, to a base station, terminal performance information including first information for displaying the supporting of a sounding reference signal transmission for positioning in an inactive state, and second information for displaying the supporting of the sounding reference signal transmission for positioning in a connection state; receiving, from the base station, a wireless resource control reconfiguration including a first sounding reference signal configuration of a first bandwidth part of a first cell; receiving, from the base station, a positioning sounding reference signal MAC control element, which activates the first sounding reference signal configuration of the first bandwidth part of the first cell; performing positioning sounding reference signal transmission in the first bandwidth part of the first cell according to the first sounding reference signal configuration; receiving a wireless resource control cancellation including third information for the sounding reference signal transmission during the inactive state and a configuration for the inactive state; entering the inactive state; performing cell selection; performing the sounding reference signal transmission in the inactive state if a selected cell is a second cell; and stopping the sounding reference signal transmission of the inactive state if a new cell is re-selected.
