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 by a terminal, the method comprising:
receiving measurement report configuration information including first information associated with a number of measurement results per beam from a base station;
measuring a plurality of beams transmitted from a base station based on the measurement report configuration information;
deriving a measurement result based on measurement values of the plurality of beams; and
transmitting the measurement result to the base station,
wherein a number of the measurement values is determined based on the first information, and
wherein the first information indicates a maximum number of measurement values to be averaged per beam.

2. The method of claim 1 ,
wherein the measurement result is derived by averaging the measured values of the plurality of beams above a threshold value indicated based on second information.

3. The method of claim 1 ,
wherein the number of the measurement values is equal to or less than the number of the measurement results per beam.

4. The method of claim 2 ,
wherein the second information is received from the base station, and
wherein a report of the measurement result is triggered based on a threshold value for a measure report.

5. A terminal comprising:
a transceiver; and
at least one processor configured to:
receive measurement report configuration information including first information associated with a number of measurement results per beam from a base station,
measure a plurality of beams transmitted from a base station based on the measurement report configuration information,
derive a measurement result based on measurement values of the plurality of beams, and
transmit the measurement result to the base station,

wherein a number of the measurement values is determined based on the first information, and
wherein the first information indicates a maximum number of measurement values to be averaged per beam.

6. The terminal of claim 5 ,
wherein the measurement result is derived by averaging the measured values of the plurality of beams above a threshold value indicated based on second information.

7. The terminal of claim 5 ,
wherein the number of the measurement values is equal to or less than the number of the measurement results per beam.

8. The terminal of claim 6 ,
wherein the second information is received from the base station, and
wherein a report of the measurement result is triggered based on a threshold value for a measure report.

9. A method by a base station, the method comprising:
transmitting measurement report configuration information including first information associated with a number of measurement results per beam to a terminal;
transmitting signals based on a plurality of beams to the terminal; and
receiving a measurement result from the terminal,
wherein the measurement result is derived based on measurement values of the plurality of beams,
wherein a number of the measurement values is determined based on the first information, and
wherein the first information indicates a maximum number of measurement values to be averaged per beam.

10. The method of claim 9 ,
wherein the measurement result is derived by averaging the measured values of the plurality of beams above a threshold value indicated based on second information.

11. The method of claim 9 ,
wherein the number of the measurement values is equal to or less than the number of the measurement results per beam.

12. The method of claim 10 ,
wherein the second information is received from the base station, and
wherein a report of the measurement result is triggered based on a threshold value for a measure report.

13. A base station comprising:
a transceiver; and
at least one processor configured to:
transmit measurement report configuration information including first information associated with a number of measurement results per beam to a terminal,
transmit signals based on a plurality of beams to the terminal, and
receive a measurement result from the terminal,

wherein the measurement result is derived based on measurement values of the plurality of beams,
wherein a number of the measurement values is determined based on the first information, and
wherein the first information indicates a maximum number of measurement values to be averaged per beam.

14. The base station of claim 13 ,
wherein the measurement result is derived by averaging the measured values of the plurality of beams above a threshold value indicated based on second information.

15. The base station of claim 13 ,
wherein the number of the measurement values is equal to or less than the number of the measurement results per beam.

16. The base station of claim 14 ,
wherein the second information is received from the base station, and
wherein a report of the measurement result is triggered based on a threshold value for a measure report.
