wherein the reference configured by the second configuration information has a highest priority for measurement,
wherein each of the at least one PRS resource is allocated with each of at least one PRS resource identifier (ID), respectively, and
wherein the at least one PRS resource is sorted in decreasing order of the priority for measurement.
2. The method of claim 1 ,
wherein at least one PRS resource set ID is respectively assigned to the at least one PRS resource set, and
wherein the at least one PRS resource set is sorted according to the priority.
3. The method of claim 1 , wherein, based on the second configuration at least comprising information related to at least one reference PRS resource set:
(i) the at least one reference PRS resource set is included in the at least one PRS resource set; and
(ii) the at least one reference PRS resource is included in the at least one PRS resource.
4. The method of claim 1 , wherein based on (i) a number of the at least one PRS resource set, or (ii) a number of the at least one PRS resource, exceeding a PRS processing capability of the UE, the measurement is performed based on the priority.
5. The method of claim 1 ,
wherein a plurality of PRSs are received based on the first configuration information, and
wherein an object for the measurement is determined from among the plurality of PRSs based on the priority.
6. The method of claim 1 wherein at least one of: (i) the at least one reference PRS resource set, and (ii) the at least one reference PRS resource, has the highest priority for measurement.
7. A user equipment (UE) operating 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:
receive first configuration information related to a positioning reference signal (PRS) and second configuration information regarding a reference;
and
perform a measurement based on the first configuration information and a priority for the measurement,
wherein the first configuration information comprises information related to at least one PRS resource set, and information related to at least one PRS resource,
wherein the second configuration information comprises at least one of: (i) information related to at least one reference PRS resource set, and (ii) information related to at least one reference PRS resource,
wherein the reference configured by the second configuration information has a highest priority for measurement,
wherein each of the at least one PRS resource is allocated with each of at least one PRS resource identifier (ID), respectively, and
wherein the at least one PRS resource is sorted in decreasing order of the priority for measurement.
8. The UE of claim 7 , wherein the at least one processor is further configured to communicate with at least one of: a mobile terminal, a network, or an autonomous driving vehicle other than a vehicle comprising the UE.
9. A method performed by a base station (BS) in a wireless communication system, the method comprising:
transmitting first configuration information related to a positioning reference signal (PRS) and second configuration information regarding a reference;
and
receiving information regarding a measurement related to positioning,
wherein the measurement is based on a priority for the measurement,
wherein the first configuration information comprises information related to at least one PRS resource set, and information related to at least one PRS resource,
wherein the second configuration information comprises at least one of: (i) information related to at least one reference PRS resource set, and (ii) information related to at least one reference PRS resource,
wherein the reference configured by the second configuration information has a highest priority for measurement,
wherein each of the at least one PRS resource is allocated with each of at least one PRS resource identifier (ID), respectively, and
wherein the at least one PRS resource is sorted in decreasing order of the priority for measurement.
10. A base station (BS) operating in a wireless communication system, the BS comprising:
a transceiver; and
at least one processor coupled with the transceiver,
wherein the at least one processor is configured to:
transmit first configuration information related to a positioning reference signal (PRS) and second configuration information regarding a reference;
receive information regarding a measurement related to positioning,
wherein the measurement is based on a priority for the measurement,
wherein the first configuration information comprises information related to at least one PRS resource set, and information related to at least one PRS resource,
wherein the second configuration information comprises at least one of: (i) information related to at least one reference PRS resource set, and (ii) information related to at least one reference PRS resource,
wherein the reference configured by the second configuration information has a highest priority for measurement,
wherein each of the at least one PRS resource is allocated with each of at least one PRS resource identifier (ID), respectively, and
wherein the at least one PRS resource is sorted in decreasing order of the priority for measurement.
