Abstract

The present disclosure relates to a 5G generation or pre-5G communication system for supporting a higher data transmission rate than a 4G communication system such as LTE. A method of an electronic device according to various embodiments of the present disclosure includes: receiving a first signal transmitted from another electronic device in a first state through a first beam; in response to the electronic device entering a designated mode, activating a sensor for detecting a change in a state of the electronic device; in response to a detection that the state of the electronic device changes from the first state to a second state using the activated sensor, determining at least one value for indicating the second state; changing a beam for receiving a signal from the first beam to a second beam based on the determined at least one value; and receiving a second signal transmitted from the another electronic device through the second beam.

First claim

What is claimed is:

1 . A method for operating an electronic device in a wireless communication, the method comprising:
receiving, from another electronic device, a first signal in a first state through a first beam; detecting a change of a state from the first state to a second state of the electronic device in a designated mode by activating a sensor; determine at least one value for indicating the second state based on the change of the state; changing a beam for receiving a signal from the first beam to a second beam based on the at least one value; receiving, from the another electronic device, a second signal in the second state through the second beam.

2 . The method of claim 1 , wherein the designated mode comprises a mode for initiating decoding of control information received from the another electronic device in a discontinuous reception (DRX) cycle.

3 . The method of claim 2 , further comprising:
decoding the control information; and if the decoded control information does not comprise information on data, inactivating the activated sensor.

4 . The method of claim 1 , wherein the designated mode comprises includes a mode for initiating reception of a paging signal from the another electronic device.

5 . The method of claim 4 , further comprising:
if information for identifying the electronic device is not included in the paging signal, inactivating the activated sensor.

6 . The method of claim 1 , wherein the designated mode comprises a mode for initiating execution of an application that causes the state of the electronic device to be changed.

7 . The method of claim 6 , further comprising, in response to the application being terminated, inactivating the activated sensor.

8 . The method of claim 1 , wherein the sensor comprises a gyro sensor, and
wherein determining the at least one value comprises, in response to a detection that the state of the electronic device changes from the first state to the second state using the activated sensor, determining the at least one value indicating a rotation change of the electronic device between the first state and the second state.

9 . The method of claim 1 , wherein changing the beam for receiving the signal comprises:
determining a vector of a beam corresponding to the second state using the determined at least one value and a vector of the first beam; identifying an index of a beam corresponding to the determined vector of the beam from among a plurality of beam indexes by comparing the determined vector of the beam and the plurality of beam indexes; and changing the beam for receiving the signal from the first beam to the second beam corresponding to the identified index of the beam.

10 . The method of claim 1 , further comprising transmitting information on the at least one value to the another electronic device,
wherein the transmitted information on the at least one value is used to determine a beam of the another electronic device.

11 . An electronic device in a wireless communication, the electronic device comprising:
at least one transceiver; at least one sensor; at least one processor operatively coupled to the at least one transceiver and the at least one sensor, wherein the at least one processor is configured to: control to receive, from another electronic device, a first signal in a first state through a first beam; detect a change of a state from the first state to a second state of the electronic device in a designated mode by activating the at least one sensor; determine at least one value for indicating the second state based on the change of the state; change a beam for receiving a signal from the first beam to a second beam based on the at least one value; and control to receive, from the another electronic device, a second signal in the second state through the second beam.

12 . The electronic device of claim 11 , wherein the designated mode comprises a mode for initiating decoding of control information received from the another electronic device in a discontinuous reception (DRX) cycle.

13 . The electronic device of claim 12 , wherein the at least one processor is further configured to:
decode the control information; and if the decoded control information does not comprise information on data, inactivate the activated at least one sensor.

14 . The electronic device of claim 11 , wherein the designated mode comprises a mode for initiating reception of a paging signal from the another electronic device.

15 . The electronic device of claim 14 , wherein the at least one processor is further configured to:
if information for identifying the electronic device is not included in the paging signal, inactivate the activated at least one sensor.

16 . The electronic device of claim 11 , wherein the designated mode comprises a mode for initiating execution of an application that causes the state of the electronic device to be changed.

17 . The electronic device of claim 16 , wherein the at least one processor is further configured to, in response to the application being terminated, inactivate the activated at least one sensor.

18 . The electronic device of claim 11 , wherein the at least one sensor comprises a gyro sensor, and
wherein the at least one processor is configured to, in response to it being detected that the state of the electronic device changes from the first state to the second state using the activated at least one sensor, determine the at least one value indicating a rotation change of the electronic device between the first state and the second state.

19 . The electronic device of claim 11 , wherein the at least one processor is configured to:
determine a vector of a beam corresponding to the second state of the electronic device using the determined at least one value and a vector of the first beam; identify an index of a beam corresponding to the determined vector of the beam from among a plurality of beam indexes by comparing the determined vector of the beam and the plurality of beam indexes; and change the beam for receiving the signal from the first beam to the second beam corresponding to the identified index of the beam.
