wherein the first assistance data comprises information related to a change of a value of at least one of information element (IE) among IEs included in the second assistance data.
5. A user equipment (UE) configured to operate in a wireless communication system, the UE comprising:
a transceiver; and
at least one processor coupled with the transceiver,
wherein the at least one processor is configured to:
transmit a first message related to a random access procedure, wherein the first message comprises a physical random access channel (PRACH) preamble;
receive a second message related to the random access procedure in response to the first message, wherein the second message comprises first assistance data related to positioning;
receive a positioning reference signal (PRS) related to the first assistance data; and
transmit a third message related to the random access procedure,
wherein the third message comprises information related to at least one measurement based on the PRS,
wherein the third message is transmitted based on scheduling information for the third message, included in the second message,
wherein the apparatus is configured in a radio resource control (RRC) idle state or RRC inactive state,
wherein the information related to the at least one measurement based on the PRS is based on a reporting range defined by a predetermined first resolution for the RRC idle state or RRC inactive state within a predetermined range, and
wherein a value of the first resolution is larger than a value of a second resolution predetermined for an RRC connected state.
6. The UE according to claim 5 , wherein the PRACH preamble is included in a plurality of PRACH preambles,
wherein the plurality of PRACH preambles comprise (i) at least one first PRACH preamble configured for at least one of a contention-based random access procedure or a contention-free random access procedure, and (ii) at least one second PRACH preamble configured for the positioning, and
wherein the second message comprises the first assistance data based on the PRACH preamble being included in the at least one second PRACH preamble.
7. The UE according to claim 6 , wherein information related to a total number of PRACH preambles available for the contention-based random access procedure and the contention-free random access procedure is received in system information, and
wherein the at least one second PRACH preamble is:
at least a part of at least one PRACH preamble available for other purposes except for the total number of preambles, or
at least a part of PRACH preambles available for the contention-free random access procedure among the total number of PRACH preambles.
8. The UE according to claim 5 , wherein the at least one processor is further configured to receive, in system information, second assistance data for the positioning, and
wherein the first assistance data comprises information related to a change of a value of at least one information element (IE) among IEs included in the second assistance data.
9. The UE according to claim 5 , wherein the at least one processor is further configured to communicate at least one of a mobile terminal, a network, or an autonomous driving vehicle other than a vehicle comprising the UE.
