Claim 0:
1. A method performed by a terminal, the method comprising:
transmitting, by the terminal to a base station, a UECapabilityInformation, the UECapabilityInformation including a first capability information related to Sounding Reference Signal (SRS) and a second capability information related to SRS;
transmitting, by the terminal to a Location Management Function (LMF), a provideCapabilities, the provideCapabilities including a capability information related to SRS support in RRC_INACTIVE;
receiving, by the terminal from the base station, a RRCRelease, the RRCRelease including a first information and a second information, wherein the first information is related to a configuration of SRS in RRC_INACTIVE and the second information includes information related to a Bandwidth Part (BWP) and information indicating a supplementary uplink; and
transmitting, by the terminal, based at least in part on the first information and the second information, a positioning SRS in RRC_INACTIVE state in a first BWP in a first cell,
wherein the first cell is a cell where the configuration of SRS in RRC_INACTIVE is received,
wherein the first BWP is determined based on the second information,
wherein the transmitting the positioning SRS in RRC_INACTIVE state comprises:
determining a frequency resource of the positioning SRS based on the first information;
determining a frequency domain based on the second information;
determining transmission power of the positioning SRS based on the first information; and
transmitting the positioning SRS in the frequency resource in the frequency domain,

wherein the positioning SRS is transmitted within the frequency domain.
