US 11,147,022 B2 · Transmit power control method and apparatus, device, and storage medium

Abstract

When a transmission overlap between uplink carriers of at least two PUCCH groups exists in time domain, obtaining, by the terminal device, minimum reserved power of each PUCCH group based on transmission duration and/or transmission content; during transmission of uplink information, transmitting the uplink information after reducing power of an uplink carrier of each PUCCH group based on maximum transmit power and minimum reserved power of the uplink carrier of each PUCCH group, where transmit power of the uplink carrier after power reduction cannot be lower than the minimum reserved power; and if power on an overlapping part of an uplink carrier of a first PUCCH group is lower than minimum reserved power of the first PUCCH group, discarding information on the overlapping part of the uplink carrier of the first PUCCH group.

Dependent claims

A method, comprising:

when an overlap between at least two channels exists in a time domain, performing power control on the at least two channels based on whether respective transmission contents of channels of the at least two channels comprise uplink control information (UCI);
and
transmitting uplink information on the at least two channels according to the performed power control;
and
wherein the at least two channels comprise a first channel and a second channel, and performing the power control comprises:
when the first channel comprises UCI and the second channel does not comprises UCI, adjusting transmit power of the first channel and transmit power of the second channel based on a maximum transmit power, a first proportion, and a second proportion, the first proportion smaller than the second proportion.

3 more elements

An apparatus, comprising:

a non-transitory storage medium including executable instructions;
and
a processor;
and
wherein the executable instructions, when executed by the processor, cause the apparatus to:
when an overlap between at least two channels exists in a time domain, perform power control on the at least two channels based on whether respective transmission contents of channels of the at least two channels comprise uplink control information (UCI), and transmit uplink information on the at least two channels according to the performed power control;
and
wherein the at least two channels comprise a first channel and a second channel, and performing the power control comprises:
when the first channel comprises UCI and the second channel does not comprises UCI, adjusting transmit power of the first channel and transmit power of the second channel based on a maximum transmit power, a first proportion, and a second proportion, the first proportion smaller than the second proportion.

6 more elements

A non-transitory computer-readable storage medium, comprising executable instructions, wherein the executable instructions, when executed by a computer, cause the computer to:

when an overlap between at least two channels exists in a time domain, perform power control on the at least two channels based on whether respective transmission contents of channels of the at least two channels comprise uplink control information (UCI), and transmit uplink information on the at least two channels according to the performed power control;
and
wherein the at least two channels comprise a first channel and a second channel, and performing the power control comprises:
when the first channel comprises UCI and the second channel does not comprises UCI, adjusting transmit power of the first channel and transmit power of the second channel based on a maximum transmit power, a first proportion, and a second proportion, the first proportion smaller than the second proportion.
