9. A user equipment (UE) in a communication system, the UE comprising:
a transceiver; and
a processor coupled with the transceiver and configured to:
receive a radio resource control (RRC) release message including first configuration information on a sounding reference signal (SRS) for positioning in an RRC inactive state, wherein the first configuration information on the SRS for positioning in the RRC inactive state includes identities of cells where the first configuration information on the SRS for positioning in the RRC inactive state is valid,
identify that a camped cell is included in the cells where the first configuration information on the SRS for positioning in the RRC inactive state is valid, and
while in the RRC inactive state, transmit, on the camped cell, the SRS for positioning in the RRC inactive state, based on the first configuration information on the SRS for positioning in the RRC inactive state,
wherein the processor is further configured to:
receive second configuration information on a positioning reference signal (PRS), in an RRC connected state,
receive the PRS in an RRC idle state or the RRC inactive state, based on the second configuration information; and
transmit, to a base station, a result of a downlink positioning measurement measured based on the PRS,
wherein the result of the downlink positioning measurement is transmitted in at least one of a physical uplink shared channel (PUSCH) in a contention-based random access procedure, a PUSCH in a non-contention-based random access procedure, a preconfigured PUSCH, or a dynamically scheduled PUSCH.
