Beamforming method and electronic device therefor

1. An electronic device comprising:

a housing;

a first antenna array positioned on the housing and/or inside the housing;

a second antenna array spaced from the first antenna array and positioned on the housing and/or inside the housing; and

at least one communication processor electrically connected to the first antenna array and the second antenna array and configured to transmit and/or receive a signal using beamforming,

wherein the at least one communication processor is configured to:

perform first beam tracking on a first component carrier associated with a base station, using the first antenna array;

determine a first direction for beamforming for communication with the base station based at least partly on a result of the first beam tracking; and

perform second beam tracking on a second component carrier by partly using the first direction, using the second antenna array.

2. The electronic device of claim 1 , wherein the at least one communication processor is further configured to:

use the first direction for beamforming for communication with the base station with respect to the second component carrier, using the second antenna array.

3. The electronic device of claim 1 , wherein the at least one communication processor is configured to:

determine a second direction different from the first direction for communication with the base station, based at least partly on a result of the second beam tracking for beamforming.

4. The electronic device of claim 1 , wherein the at least one communication processor is configured to:

perform the first beam tracking during a first time interval; and

perform the second beam tracking during a second time interval shorter than the first time interval.

5. The electronic device of claim 1 , wherein the base station includes a transmission/reception point (TRP).

6. The electronic device of claim 1 , wherein the result of the first beam tracking includes a value associated with a phase.

7. The electronic device of claim 1 , wherein the first component carrier is a primary component carrier (PCC), and the second component carrier is a secondary component carrier (SCC).

8. The electronic device of claim 1 , wherein the first component carrier and the second component carrier are set in a band between 3 GHz and 100 GHz.

9. The electronic device of claim 3 , wherein the at least one communication processor is configured to:

transmit or receive a control signal or a data signal with the base station through the first component carrier, using the first direction; and

transmit or receive a control signal or a data signal with the base station through the second component carrier, using the second direction.

10. The electronic device of claim 1 , wherein the first component carrier is set in a licensed band, and the second component carrier is set in an unlicensed band.

11. A method comprising:

performing first beam tracking on a first component carrier associated with a base station, using a first antenna array;

determining a first direction for beamforming for communication with the base station based at least partly on a result of the first beam tracking; and

performing second beam tracking on a second component carrier based partly on the first direction, using the second antenna array.

12. The method of claim 11 , wherein the performing of the second beam tracking includes:

performing the second beam tracking, using the first direction.

13. The method of claim 11 , further comprising:

determining a second direction for beamforming for communication with the base station based at least partly on a result of the second beam tracking.

14. The method of claim 11 ,

wherein the first beam tracking is performed during a first time interval, and

wherein the second beam tracking is performed during a second time interval shorter than the first time interval.

15. The method of claim 11 , wherein the result of the first beam tracking includes a value associated with a phase.
