Abstract

An example electronic device may include multiple antennas and at least one processor, wherein the at least one processor is configured to: identify a sounding reference signal (SRS) configuration received from a network; identify a physical downlink shared channel (PDSCH) scheduling rate corresponding to the electronic device; transmit, based on the PDSCH scheduling rate not being included in a first range, at least one SRS at the magnitude of first transmission power, in each of one or more resource for SRS signal transmission identified on the basis of the SRS configuration; and refrain from transmitting the at least one SRS in the one or more resources based on the PDSCH scheduling rate being included in the first range, or transmit the at least one SRS at the magnitude of second transmission power, in the each of the one or more resources.

First claim

What is claimed is:

1 . An electronic device comprising:
a plurality of antennas; memory, including one or more storage media, storing instructions; at least one processor including processing circuitry, wherein the instructions, when executed by at least one processor individually or collectively, cause the electronic device to:
identify a sounding reference signal (SRS) configuration received from a network, wherein the SRS configuration is configured by the network corresponding to the plurality of antennas;
identify a physical downlink shared channel (PDSCH) scheduling rate corresponding to the electronic device, wherein the PDSCH scheduling rate is a ratio of scheduled slots among total slots of the PDSCH corresponding to the electronic device for a specified period;
based on the PDSCH scheduling rate not being included in a first range:
transmit at least one SRS at a magnitude of first transmission power through each of at least one of the plurality of antennas, in each of at least one resource for SRS signal transmission identified based on the SRS configuration; and

based on the PDSCH scheduling rate being included in the first range:
refrain from transmitting the at least one SRS in the at least one resource, or
transmit the at least one SRS at a magnitude of second transmission power, through at least one of the plurality of antennas, in the at least one resource, respectively, wherein the magnitude of the second transmission power is different from the magnitude of the first transmission power.

2 . The electronic device of claim 1 , wherein, as at least a part of the transmitting the at least one SRS at the magnitude of the second transmission power based on the PDSCH scheduling rate being included in the first range, instructions, when executed by at least one processor, comprising processing circuitry, individually or collectively cause the electronic device to:
determine, as the magnitude of the second transmission power, a magnitude of pre-specified transmission power; determine, as the magnitude of the second transmission power, a magnitude of transmission power, obtained by backing off a first value from the magnitude of the first transmission power; or determine, as the magnitude of the second transmission power, a magnitude of transmission power, obtained by multiplying the magnitude of the first transmission power by a second value.

3 . The electronic device of claim 2 , wherein, as at least a part of the determining the magnitude of the second transmission power, obtained by backing off a first value from the magnitude of the first transmission power, instructions, when executed by at least one processor, comprising processing circuitry, individually or collectively cause the electronic device to:
determine the magnitude of the second transmission power by subtracting the first value, which is a specified back-off value, from the magnitude of the first transmission power, or determine the magnitude of the second transmission power by subtracting the first value, which is identified based on the magnitude of the first transmission power, from the magnitude of the first transmission power.

4 . The electronic device of claim 1 , wherein, as at least a part of the refraining from transmitting the at least one SRS in the at least one resource, or the transmitting the at least one SRS at the magnitude of the second transmission power, based on the PDSCH scheduling rate being included in the first range, instructions, when executed by at least one processor, comprising processing circuitry, individually or collectively cause the electronic device to:
refrain from transmitting the at least one SRS, based on identifying that a difference between an SRS target power for transmitting the at least one SRS by the electronic device and a maximum power supported by the electronic device is included in a second range; or transmit the at least one SRS at the magnitude of the second transmission power.

5 . The electronic device of claim 4 , wherein, as at least part of the refraining from transmitting the at least one SRS in the at least one resource, or transmitting the at least one SRS with the magnitude of the second transmission power, based on the PDSCH scheduling rate being included in the first range, instructions, when executed by at least one processor, comprising processing circuitry, individually or collectively cause the electronic device to:
refrain from transmitting the at least one SRS, based on identifying that the SRS target power for transmitting the at least one SRS by the electronic device is included in a third range; or transmit the at least one SRS at the magnitude of the second transmission power.

6 . The electronic device of claim 1 , wherein instructions, when executed by at least one processor, comprising processing circuitry, individually or collectively cause the electronic device to:
identify at least one first parameter related to reception strength, while refraining from transmitting the at least one SRS or while transmitting the at least one SRS at the magnitude of the second transmission power; and transmit the at least one SRS transmission at the magnitude of the first transmission power, based on the at least one first parameter satisfying a specified condition.

7 . The electronic device of claim 6 , wherein, as at least a part of the transmitting the at least one SRS transmission at the magnitude of the first transmission power, based on the at least one first parameter satisfying a specified condition, instructions, when executed by at least one processor, comprising processing circuitry, individually or collectively cause the electronic device to:
transmit the at least one SRS transmission at the magnitude of the first transmission power, based on a comparison result between at least one second parameter and the at least one first parameter satisfying a first specified condition, wherein the at least one second parameter is identified while the at least one SRS is transmitted; or transmit the at least one SRS transmission at the magnitude of the first transmission power, based on the at least one first parameter satisfying a second specified condition.
