Abstract

The present disclosure relates to a pre-5th-Generation (5G) or 5G communication system to be provided for supporting higher data rates Beyond 4th-Generation (4G) communication system such as Long Term Evolution (LTE). Disclosed is a method of reporting beam measurement state information by a User Equipment (UE). The method may include: measuring beam state information by using a first reception chain and a second reception chain; controlling beam state information on the first reception chain to correspond to beam state information on the second reception chain; calculating state information on each beam based on the controlled beam state information on the first reception chain and beam state information on the second reception chain; and reporting state information on one or more beams.

First claim

The invention claimed is:

1. A method performed by a terminal in a wireless communication system, the method comprising:
receiving, from a base station, first information associated with a number of measurement samples to be averaged;
obtaining measurement samples by measuring signals of a plurality of beams;
deriving a measurement result based on the measurement samples and the number of measurement samples to be averaged; and
transmitting, to the base station, the measurement result to the base station.

2. The method of claim 1 ,
wherein the number of the measurement samples is determined based on the first information configured by a unicast signaling.

3. The method of claim 1 ,
wherein a total number of the measurement samples used for the measurement result is equal to or less than the number of the measurement samples.

4. The method of claim 1 ,
wherein measurement samples which are larger than or equal to a threshold are used to calculate an average for the measurement result.

5. The method of claim 1 ,
wherein a report of the measurement result is triggered based on a threshold value for a measurement report.

6. A terminal in a wireless communication system, the terminal comprising:
a transceiver; and
a controller configured to:
receive, from a base station via the transceiver, first information associated with a number of measurement samples to be averaged,
obtain measurement samples by measuring signals of a plurality of beams,
derive a measurement result based on the measurement samples and the number of measurement samples to be averaged, and
transmit, to the base station via the transceiver, the measurement result to the base station.

7. The terminal of claim 6 ,
wherein the number of the measurement samples is determined based on the first information configured by a unicast signaling.

8. The terminal of claim 6 ,
wherein a total number of the measurement samples used for the measurement result is equal to or less than the number of the measurement samples.

9. The terminal of claim 6 ,
wherein measurement samples which are larger than or equal to a threshold are used to calculate an average for the measurement result.

10. The terminal of claim 6 ,
wherein a report of the measurement result is triggered based on a threshold value for a measurement report.

11. A method performed by a base station in a wireless communication system, the method comprising:
transmitting, to a terminal, first information associated with a number of measurement samples to be averaged; and
receiving, from the terminal, a measurement result which is derived based on a plurality of measurement samples and the number of measurement samples to be averaged.

12. The method of claim 11 , wherein the number of the measurement samples is determined based on the first information configured by a unicast signaling.

13. The method of claim 11 ,
wherein a total number of the plurality of measurement samples used for the measurement result is equal to or less than the number of the measurement samples.

14. The method of claim 11 ,
wherein measurement samples which are larger than or equal to a threshold are used to calculate an average for the measurement result.

15. The method of claim 11 ,
wherein a report of the measurement result is triggered based on a threshold value for a measurement report.

16. A base station in a wireless communication system, the base station comprising:
a transceiver; and
a controller configured to:
transmit, to a terminal via the transceiver, first information associated with a number of measurement samples to be averaged, and
receive, from the terminal via the transceiver, a measurement result which is derived based on a plurality of measurement samples and the number of measurement samples to be averaged.

17. The base station of claim 16 , wherein the number of the measurement samples is determined based on the first information configured by a unicast signaling.

18. The base station of claim 16 ,
wherein a total number of the plurality of measurement samples used for the measurement result is equal to or less than the number of the measurement samples.

19. The base station of claim 16 ,
wherein measurement samples which are larger than or equal to a threshold are used to calculate an average for the measurement result.

20. The base station of claim 16 ,
wherein a report of the measurement result is triggered based on a threshold value for a measurement report.
