Abstract

A method and an electronic device are provided for controlling power of the electronic device. Uplink resource information allocated to the electronic device from a base station is received via a first wireless communication circuit configured to transmit and/or receive a first signal of 6 GHz or less. A power modulator of the electronic device controls a power of at least one wireless communication circuit, from among the first wireless communication circuit and a second wireless communication circuit configured to transmit and/or receive a second signal of 6 GHz or less, with APT based on at least the number of uplink resource blocks indicated by the uplink resource information.

First claim

What is claimed is:

1. An electronic device comprising:
a housing;
a first antenna;
a second antenna;
a first wireless communication circuit electrically connected to the first antenna and configured to transmit and/or receive a first signal having a first frequency between 500 MHz and 6 GHz;
a first power modulator included in the first wireless communication circuit or connected to the first wireless communication circuit, and configured to provide the first wireless communication circuit with a first voltage based on envelope tracking (ET) or average power tracking (APT);
a second wireless communication circuit electrically connected to the second antenna and configured to transmit and/or receive a second signal having a second frequency between 500 MHz and 6 GHz;
a second power modulator included in the second wireless communication circuit or connected to the second wireless communication circuit and configured to provide the second wireless communication circuit with a second voltage based on the ET or the APT;
at least one processor operatively connected to the first wireless communication circuit and the second wireless communication circuit; and
a memory operatively connected to the at least one processor or coupled with the at least one processor,
wherein the memory stores one or more instructions that, when executed, cause the at least one processor to:
receive uplink resource information allocated to the electronic device from a base station, via the first wireless communication circuit;
cause at least one power modulator, from among the first power modulator and the second power modulator, to provide a voltage based on the APT, based on a number of uplink resource blocks indicated by the uplink resource information;

obtain information about a first frequency band associated with the first wireless communication circuit and information about a second frequency band associated with the second wireless communication circuit;
when a multiple of the first frequency band overlaps with at least part of the second frequency band, determine whether a multiple of a first channel associated with the first wireless communication circuit in the first frequency band at least partially overlaps with a band of a second channel associated with the second wireless communication circuit in the second frequency band; and
when the multiple of the first channel at least partly overlaps with the band of the second channel, control the at least one power modulator to provide the power based on the APT.

2. The electronic device of claim 1 , wherein the one or more instructions, when executed, further cause the at least one processor to:
obtain first frequency band information of the first channel and second frequency band information of the second channel, using first channel information of a first network provider associated with the first frequency band and second channel information of a second network provider associated with the second frequency band.

3. The electronic device of claim 1 ,

when a number of uplink resource blocks is less than a threshold value and the multiple of the first channel at least partially overlaps with the band of the second channel, changing the power providing method of the power modulator of the at least one wireless communication circuit into the APT.

4. The electronic device of claim 1 , wherein the one ore more instructions, when executed, cause the at least one processor to:

5. The electronic device of claim 1 , wherein the one or more instructions, when executed, cause the at least one processor to:
when the identified electric field is greater than or equal to a threshold value, control a power providing method of the second power modulator included in the second wireless communication circuit with an ET and reduce a maximum transmission power of the first wireless communication circuit.

6. The electronic device of claim 5 , wherein:
when the identified electric field is less than the threshold value, the one or more instructions, when executed, cause the at least one processor to control the power based on the APT.

7. The electronic device of claim 6 , wherein:
when the identified electric field is less than the threshold value, the one or more instructions, when executed, cause the at least one processor to add an offset voltage to an output voltage of the second power modulator.

8. An electronic device comprising:
a housing;
a first antenna;
a second antenna;
a first wireless communication circuit electrically connected to the first antenna and configured to transmit and/or receive a first signal having a first frequency between 500 MHz and 6 GHz;
a first power modulator included in the first wireless communication circuit or connected to the first wireless communication circuit, and configured to provide the first wireless communication circuit with a first voltage based on envelope tracking (ET) or average power tracking (APT);
a second wireless communication circuit electrically connected to the second antenna and configured to transmit and/or receive a second signal having a second frequency between 500 MHz and 6 GHz;
a second power modulator included in the second wireless communication circuit or connected to the second wireless communication circuit and configured to provide the second wireless communication circuit with a second voltage based on the ET or the APT;
at least one processor operatively connected to the first wireless communication circuit and the second wireless communication circuit; and
a memory operatively connected to the at least one processor or coupled with the at least one processor,
wherein the memory stores one or more instructions that, when executed, cause the at least one processor to:
receive uplink resource information allocated to the electronic device from a base station, via the first wireless communication circuit;

when the number of uplink resource blocks is greater than or equal to a defined number, identify an electric field associated with the first wireless communication circuit; and
when the identified electric field is greater than or equal to a threshold value, cause the second power modulator to provide a voltage based on the ET and to reduce a maximum transmission power of the first wireless communication circuit.

9. The electronic device of claim 8 , wherein the one or more instructions, when executed, further cause the at least one processor to:
