1. A method by a terminal, the method comprising:
transmitting, by the terminal to a base station, a UECapabilityInformation, the UECapabilityInformation includes one or more first capability information related to Sounding Reference Signal (SRS), at most one first capability information is included per feature set;
transmitting, by the terminal to a Location Management Function (LMF), a provideCapabilities, the provideCapabilities includes one or more second capability information related to support of Sounding Reference Signal (SRS) in RRC_INACTIVE, at most one second capability information is included per frequency band;
receiving, by the terminal from the base station, a RRCRelease, the RRCRelease includes a first information and a second information and optionally a third information, the first information includes configuration information of SRS in RRC_INACTIVE, the second information includes information for Bandwidth Part (BWP), the third information includes information on supplementary uplink;
transmitting, by the terminal in a first cell based on the first information and the second information and presence of the third information, positioning SRS in a specific uplink in RRC_INACTIVE; and
stopping, by the terminal, transmission of positioning SRS in RRC_INACTIVE if a specific message including a fourth information is received in the first cell,
wherein the fourth information is a one bit information indicating to stop SRS transmission, and
wherein the specific uplink is supplementary uplink if the third information is present in the RRCRelease and the specific uplink is a normal uplink if the third information is not present in the RRCRelease.
