wherein the obtaining of the measurement value comprises:
acquiring a plurality of samples based on at least one RS among the plurality of RSs; and
obtaining the measurement value based on a filter that applies a plurality of weight factors to the plurality of samples, respectively, wherein the plurality of weight factors are configured through network signaling.
2. The method of claim 1 , wherein:
(i) based on information related to a time window for the positioning being obtained, the at least one RS are included in the time window; or
(ii) based on information related to the number of measurement samples being obtained, the number of the plurality of samples is less than or equal to the number of the measurement samples.
3. The method of claim 2 , wherein, based on the information related to the time window being obtained, RSs other than the at least one RS among the plurality of RSs are not included in the time window.
4. The method of claim 2 , further comprising:
based on the information related to the time window being autonomously obtained by the apparatus, transmitting the information related to the time window.
5. The method of claim 2 , wherein each of the plurality of RSs is received based on a periodically configured positioning reference signal (PRS),
wherein a size of a period of the periodically configured PRS is less than or equal to a size of the time window.
6. The method of claim 1 , wherein the filter is related to
Σ n=1 L R n a n ,
wherein L is the number of the plurality of samples, R n is an n-th sample among the plurality of samples, and a n is a weight factor used for the n-th sample.
7. The method of claim 6 , further comprising:
receiving information related to the plurality of weight factor.
8. The method of claim 1 , further comprising at least one of:
transmitting information related to the plurality of samples; or
transmitting information related to the filter.
9. A user equipment (UE) comprising:
a transceiver; and
at least one processor coupled with the transceiver;
wherein the at least one processor is configured to:
receive a plurality of reference signals (RSs) related to positioning;
obtain a measurement value related to the positioning; and
report information regarding the measurement value,
wherein, in obtaining the measurement value, the at least one processor is configured to:
acquire a plurality of samples based on at least one RS among the plurality of RSs; and
obtain the measurement value based on a filter that applies a plurality of weight factors to the plurality of samples, respectively, wherein the plurality of weight factors are configured through network signaling.
10. The UE of claim 9 , wherein the filter is related to
Σ n=1 L R n a n ,
wherein L is the number of the plurality of samples, R n is an n-th sample among the plurality of samples, and a n is a weight factor used for the n-th sample.
11. The UE of claim 9 , wherein the at least one processor is configured to:
communicate with one or more of a mobile terminal, a network, and an autonomous vehicle other than a vehicle containing the terminal.
12. A method performed by an apparatus, the method comprising:
transmitting, to another apparatus, information regarding a plurality of weight factors of a filter;
transmitting, to the another apparatus, a reference signal (RS) related to positioning; and
receiving, from the another apparatus, information regarding a measurement value for a plurality of samples of the RS related to the positioning,
wherein the plurality of weight factors of the filter are applied to the plurality of samples.
13. A base station comprising:
a transceiver; and
at least one processor coupled with the transceiver,
wherein the at least one processor is configured to:
transmit, to another apparatus, information regarding a plurality of weight factors of a filter;
transmit, to the another apparatus, a reference signal (RS) related to positioning; and
receive, from the another apparatus, information regarding a measurement value for a plurality of samples of the RS related to the positioning,
wherein the plurality of weight factors of the filter are applied to the plurality of samples.
