Method for transmitting and receiving signal in wireless communication system, and apparatus for supporting same
Various embodiments relate to a next generation wireless communication system for supporting a data transmission rate higher than that of a 4th generation (4G) wireless communication system, and the like. According to various embodiments, a method for transmitting and receiving a signal in a wireless communication system and an apparatus for supporting same can be provided. Various other embodiments can be provided.
1 . A method performed by a user equipment (UE), the method comprising:
receiving positioning reference signals (PRSs);
performing a measurement based on the PRSs; and
transmitting a report based on the measurement, wherein the report comprises: (i) reception beam indices and (ii) spatial filter indices used for the PRSs.
2 . The method of claim 1 , wherein receiving the PRSs comprises:
receiving a single positioning reference signal at t1 and at t2, respectively,
wherein t1 and t2 denote time points in a time domain, and
wherein the reception beam indices comprise a first reception beam index used at t1 and a second reception beam index used at t2.
3 . The method of claim 2 , wherein the report comprises information regarding whether a first spatial filter used at t1 is identical to a second spatial filter used at t2.
4 . The method of claim 3 , wherein the report comprises an azimuth angle difference between the first spatial filter and the second spatial filter, or an offset between the first spatial filter and the second spatial filter.
5 . The method of claim 1 , wherein the reception beam indices are associated with the spatial filter indices, respectively.
6 . The method of claim 1 , wherein the PRSs comprise a first PRS transmitted on a first transmission beam of a base station and a second PRS transmitted on a transmission beam adjacent to the first transmission beam of the base station,
wherein the first PRS is received on a first reception beam,
wherein the second PRS is received on a second reception beam, and
wherein the method further comprises determining whether an angle difference between the first reception beam and the second reception beam is greater than or equal to a predefined value.
7 . The method of claim 1 , wherein the reception beam indices are allocated based on absolute beam directions or physical beam directions.
8 . A user equipment (UE) comprising:
a transceiver; and
at least one processor connected to the transceiver,
wherein the at least one processor is configured to:
receive positioning reference signals (PRSs);
perform a measurement based on the PRSs; and
transmit a report based on the measurement, and wherein the report comprises: (i) reception beam indices and (ii) spatial filter indices used for the PRSs.
9 . The UE of claim 8 , wherein the processor is further configured to:
receive a single positioning reference signal at t1 and at t2, respectively,
wherein t1 and t2 denote time points in a time domain, and
wherein the reception beam indices comprise a first reception beam index used at t1 and a second reception beam index used at t2.
10 . The UE of claim 9 ,
wherein the report comprises information regarding whether a first spatial filter used at t1 is identical to the same with the a second spatial filter used at t2.
11 . The UE of claim 10 , wherein the report comprises, an azimuth angle difference between the first spatial filter and the second spatial filter, or an offset between the first spatial filter and the second spatial filter.
12 . A base station comprising:
a transceiver; and
at least one processor connected to the transceiver,
wherein the at least one processor is configured to:
transmit, to a user equipment (UE), positioning reference signals (PRSs); and
receive, from the UE, a measurement report for the PRSs,
wherein the measurement report comprises: (i) reception beam indices and (ii) spatial filter indices used at the UE for the PRSs.
