Abstract

One disclosure of the present specification provides a method by which a communication device, which performs a measurement through multiple antenna panels, reports the measurement. The method may include the steps of: transmitting capability information to a base station; receiving measurement setting information from the base station; powering on a powered-off antenna panel among the multiple antennal panels in order to perform a measurement; performing the measurement through the multiple antenna panels; and transmitting a measurement report message including information indicating whether the corresponding antenna panel was in a powered-on state or a powered-off state prior to the measurement, and information on the measurement result.

First claim

1 . A method of a communication device for performing measurements through a plurality of antenna panels, comprising:
transmitting capability information to a base station; receiving measurement configuration information from the base station; performing power-on an antenna panel in power-off state among the plurality of antenna panels for measurement; performing measurement through the plurality of antenna panels; and transmitting a measurement report message including information indicating whether the corresponding antenna panel was in power-on state or power-off state before the performing measurement, and information on a result of the measurement.

2 . The method of claim 1 , further comprising:
performing power-on all of the plurality of antenna panels, based on moving speed of the communication device being greater than or equal to the threshold speed; performing power-off some antenna panels, based on moving speed of the communication device being greater than or equal to a threshold speed.

3 . The method of claim 1 , further comprising:
performing power-off the antenna panel, which was in power off state before the performing measurement, after the performing measurement.

4 . The method of claim 1 , further comprising:
based on a result value of the measurement through antenna panel, which was in power-off state before the performing measurement, being smaller than a threshold value, performing power-off the antenna panel, which was in a power off state before the performing measurement.

5 . The method of claim 1 , further comprising:
based on a result value of the measurement through antenna panel, which was in power-off state before the performing measurement, being greater than a threshold value, maintaining power-on state of the antenna panel, which was in a power off state before the performing measurement.

6 . The method of claim 1 , further comprising: further comprising:
based on a result value of the measurement through a first antenna panel, which was in power-on state before the performing measurement, being smaller than a result value of the measurement through a second antenna panel, which was in power-off state before the performing measurement, maintaining power-on state of the second antenna panel.

7 . The method of claim 1 , further comprising:
comparing a result value of the measurement through a first antenna panel, which was in power-on state before the performing measurement, with a first threshold value; comparing a result value of the measurement through a second antenna panel, which was in power-off state before the performing measurement, with a second threshold value.

8 . The method of claim 7 ,
wherein the first threshold value and the second threshold value are included in the measurement configuration information.

9 . The method of claim 1 ,
wherein the capability information includes information indicating whether the plurality of antenna panels can be individually powered on or off.

10 . The method of claim 1 ,
wherein the communication device is a V2X (vehicle-to-everything) device, a robot, or a smartphone equipped in a vehicle.

11 . A communication device for performing measurements through a plurality of antenna panels comprising:
at least one processor; and at least one memory for storing instructions and operably electrically connectable with the at least one processor, based on the instructions being operated by the at least one processor, performed operation comprising: transmitting capability information to a base station; receiving measurement configuration information from the base station; performing power-on an antenna panel in power-off state among the plurality of antenna panels for measurement; performing measurement through the plurality of antenna panels; and transmitting a measurement report message including information indicating whether the corresponding antenna panel was in power-on state or power-off state before the performing measurement, and information on a result of the measurement.

12 . The device of claim 11 , the performed operation further comprising:
performing power-off the antenna panel, which was in power off state before the performing measurement, after the performing measurement.

13 . The device of claim 11 , the performed operation further comprising:
based on a result value of the measurement through antenna panel, which was in power-off state before the performing measurement, being smaller than a threshold value, performing power-off the antenna panel, which was in a power off state before the performing measurement.

14 . The device of claim 11 , the performed operation further comprising:
based on a result value of the measurement through antenna panel, which was in power-off state before the performing measurement, being greater than a threshold value, maintaining power-on state of the antenna panel, which was in a power off state before the performing measurement.

15 . The device of claim 11 ,
wherein the capability information includes information indicating whether the plurality of antenna panels can be individually powered on or off.

16 . A non-volatile computer readable storage medium having recorded instructions,
wherein the instructions, based on being executed by one or more processors, cause the one or more processors to: transmit capability information to a base station; receive measurement configuration information from the base station; perform power-on an antenna panel in power-off state among the plurality of antenna panels for measurement; perform measurement through the plurality of antenna panels; and transmit a measurement report message including information indicating whether the corresponding antenna panel was in power-on state or power-off state before the performing measurement, and information on a result of the measurement.
