Abstract

An electronic device is provided. The electronic device includes an antenna module, a memory, and a processor controlling to identify a first beam set among a plurality of beam sets stored in the memory, perform beamforming based on the identified first beam set through the antenna module, determine whether a beam pattern is changed, based on, at least, a prediction value of a reception signal strength set corresponding to the first beam set and a measurement value of a signal received through the antenna module, and change a setting related to a reception beam if the beam pattern is determined to be changed.

First claim

The invention claimed is:

1. An electronic device, comprising:
an antenna module;
a memory configured to store:
a first setting value corresponding to beamforming in a first state related to the electronic device,
a second setting value corresponding to beamforming in a second state related to the electronic device,
first beam set information corresponding to the first state, and
second beam set information corresponding to the second state; and

a processor configured to:
perform first beamforming based on the first beam set information, through the antenna module, in the first state,
identify a change from the first state to the second state, based on a measurement value measured by the performed first beamforming and the second setting value, and
perform second beamforming based on the second beam set information,

wherein the first setting value is a value set based on a measurement value measured from a signal received when beamforming is performed based on the first beam set information.

2. The electronic device of claim 1 , wherein the first setting value is a value set corresponding to a state in which the electronic device is not placed in a case.

3. The electronic device of claim 1 , wherein the second setting value is one of a value set corresponding to at least one of a state in which the electronic device is placed in a case, a state in which the electronic device is gripped in a user's hand, or a state in which an abnormality occurs in an antenna included in the electronic device.

4. The electronic device of claim 1 , wherein the second beam set information includes information in which at least part of information for at least one reception beam included in the first beam set information has been changed.

5. The electronic device of claim 1 , wherein the processor is further configured to control to change a hierarchical structure between a plurality of reception beams included in the first beam set information.

6. The electronic device of claim 5 , wherein the hierarchical structure includes a hierarchical structure between a plurality of wide beams and a plurality of narrow beams.

7. The electronic device of claim 6 , wherein the processor is further configured to control to exclude, from the hierarchical structure, a wide beam including a reception beam, which is selected as an optimal reception beam in a ratio less than a set value, among the plurality of wide beams.

8. The electronic device of claim 6 , wherein the processor is further configured to control to reduce a frequency of reception signal strength measurement to search for an optimal reception beam for a wide beam including a reception beam, which is selected as the optimal reception beam in a ratio less than a set value, among the plurality of wide beams.

9. The electronic device of claim 1 , wherein the processor is further configured to adjust a beam change threshold or a beam change count so that a probability of a change in reception beam becomes a set value or less.

10. A method for setting a reception beam by an electronic device, the method comprising:
identifying first beam set information corresponding to a first state related to the electronic device among a plurality of beam set information stored in a memory;
performing first beamforming based on the identified first beam set information, through an antenna module, in the first state;
identifying a change from the first state to a second state, based on a measurement value measured by the performed first beamforming and a setting value set for second beam set information corresponding to the second state related to the electronic device among the plurality of beam set information stored in the memory;
performing second beamforming based on the second beam set information;
in response to a change in a beam pattern, identifying whether an update condition of a setting related to the reception beam is met; and
in response to the update condition being met, changing the setting related to the reception beam.

11. The method of claim 10 , wherein whether the update condition is met is determined based on a distribution of a reception signal strength corresponding to each of a plurality of beam sets.

12. The method of claim 10 , wherein the change of the setting related to the reception beam includes a change from a first beam set to a second beam set.

13. The method of claim 10 , wherein the changing of the setting related to the reception beam includes adjusting a setting related to changing a reception beam.

14. The method of claim 13 , wherein the setting related to changing the reception beam includes at least one of the number of beams used, the number of antenna modules, a hierarchical structure of a beam, a beam change threshold, a beam change count, a monitoring threshold of the antenna module, a change threshold of the antenna module, a change count of the antenna module, or a context change threshold.

15. The method of claim 10 , wherein the setting related to changing the reception beam includes a setting to reduce a frequency of reception signal strength measurement to search for an optimal reception beam for a reception beam, which is selected as the optimal reception beam in a ratio less than a set value.

16. The method of claim 10 , wherein the setting related to changing the reception beam may include a setting to exclude, from beams to be used, a reception beam, which is selected as an optimal reception beam in a ratio less than a set value.
