1. A method performed by a wireless device, the method comprising:
transmitting, by the wireless device to a base station, a UECapabilityInformation, wherein the UECapabilityInformation comprises a first capability information related to Sounding Reference Signal (SRS) and a second capability information related to SRS;
receiving, by the wireless device in a first cell from the base station, a RRCRelease, wherein the RRCRelease comprises a first information and a second information and a third information, and wherein:
the first information is related to a configuration of SRS in RRC_INACTIVE,
the second information is related to a time point of stopping SRS transmission, and
the third information is related to a BandWidth Part (BWP);
transmitting, by the wireless device in the first cell to the base station, based on the first information and the third information a positioning SRS in RRC_INACTIVE state; and
stopping, by the wireless device in the first cell, transmission of the positioning SRS in RRC_INACTIVE state at a first time point,
wherein the first time point is determined based on the second information,
wherein the first information comprises parameters relating to periodicity and starting slot of the positioning SRS.
