transmitting the message,
wherein the PRACH preamble is included in a plurality of PRACH preambles configured for positioning,
wherein the plurality of PRACH preambles are distributed into a plurality of groups, and
wherein the plurality of groups are respectively related to different information elements (IEs) for a long-term evolution positioning protocol (LPP) message for the positioning.
2. The method of claim 1 , wherein the different IEs comprise:
(i) a first IE related to an LPP capability of the apparatus;
(ii) a second IE related to requesting assistance data for the positioning; and
(iii) a third IE related to providing one or more measurements for the positioning.
3. The method of claim 2 , wherein the apparatus is in a radio resource control (RRC) idle or RRC inactive state,
wherein based on the PRACH preamble being included in a group related to the third IE among the plurality of groups, the PUSCH includes information related to the one or more measurements,
wherein the information related to the one or more measurements includes information based on a reporting range defined by a first resolution preconfigured for the RRC idle or RRC inactive state within a predetermined range, and
wherein the first resolution is greater than a second resolution preconfigured for an RRC connected state.
4. The method of claim 1 , wherein information related to a number of total PRACH preambles available for a contention-based random access procedure and a contention-free random access procedure is received, and
wherein at least one of the following is satisfied:
based on reception of information related to a number of one or more PRACH preambles configured for the positioning among the total PRACH preambles, obtaining as many PRACH preambles as the number of the one or more PRACH preambles configured for the positioning among the total PRACH preambles as the one or more PRACH preambles; or
based on reception of information related to a number of one or more PRACH preambles configured for the positioning among PRACH preambles available for other purposes except for the total PRACH preambles, obtaining as many PRACH preambles as the number of the one or more PRACH preambles configured for the positioning among the PRACH preambles available for the other purposes as the one or more PRACH preambles.
5. The method of claim 1 , further comprising monitoring a positioning reference signal (PRS) related to the positioning within a time duration configured based on system information,
wherein based on failure in monitoring the PRS within the time duration, the PRACH preamble is retransmitted.
6. The method of claim 5 , wherein the PRACH preamble is transmitted on one or more PRACH occasions among a plurality of PRACH occasions,
wherein the PUSCH is transmitted on one or more PUSCH occasions among a plurality of PUSCH occasions,
wherein the one or more PUSCH occasions are located after the one or more PRACH occasions in a time domain, and
wherein based on the PRS being monitored between the one or more PRACH occasions and the one or more PUSCH occasions in the time domain, the PUSCH includes information related to one or more measurements for the positioning based on the PRS.
7. A user equipment (UE) configured to operate in a wireless communication system, the UE comprising:
a transceiver; and
one or more processors connected to the transceiver,
wherein the one or more processors are configured to:
obtain a message including a physical random access channel (PRACH) preamble and a physical uplink shared channel (PUSCH); and
transmit the message, and
wherein the PRACH preamble is included in a plurality of PRACH preambles configured for positioning,
wherein the plurality of PRACH preambles are distributed into a plurality of groups, and
wherein the plurality of groups are respectively related to different information elements (IEs) for a long-term evolution positioning protocol (LPP) message for the positioning.
8. The UE of claim 7 , wherein the different IEs comprise:
(i) a first IE related to an LPP capability of the UE;
(ii) a second IE related to requesting assistance data for the positioning; and
(iii) a third IE related to providing one or more measurements for the positioning.
9. The UE of claim 7 , wherein the one or more processors are configured to communicate with at least one of a mobile terminal, a network, or an autonomous driving vehicle other than a vehicle including the UE.
10. A method performed by an apparatus in a wireless communication system, the method comprising:
receiving a message including a physical random access channel (PRACH) preamble and a physical uplink shared channel (PUSCH); and
obtaining the PRACH preamble and the PUSCH based on the message,
wherein the PRACH preamble is included in a plurality of PRACH preambles configured for positioning,
wherein the plurality of PRACH preambles are distributed into a plurality of groups, and
wherein the plurality of groups are respectively related to different information elements (IEs) for a long-term evolution positioning protocol (LPP) message for the positioning.
11. A base station configured to operate in a wireless communication system, the base station comprising:
a transceiver; and
one or more processors connected to the transceiver,
wherein the one or more processors are configured to:
receive a message including a physical random access channel (PRACH) preamble and a physical uplink shared channel (PUSCH); and
obtain the PRACH preamble and the PUSCH based on the message,
wherein the PRACH preamble is included in a plurality of PRACH preambles configured for positioning,
wherein the plurality of PRACH preambles are distributed into a plurality of groups, and
wherein the plurality of groups are respectively related to different information elements (IEs) for a long-term evolution positioning protocol (LPP) message for the positioning.
