Abstract

Embodiments of this application provide an uplink transmission method and apparatus, a computer-readable storage medium, a computer program product, and the like, to implement intra-frequency uplink transmission by a terminal device. The method includes: determining a plurality of serving cells, where the plurality of serving cells have at least one of the following association relationships: operating frequency bands are completely the same, or the operating frequency bands are partially the same; and sending uplink signals to the plurality of serving cells, where the sending of the uplink signal meets a preset condition.

Claims18

Dependent claims

An uplink transmission method comprising:

determining a plurality of serving cells, wherein operating frequency bands of the plurality of serving cells are partially the same;
sending uplink signals to the plurality of serving cells when the sending of the uplink signals meets a preset condition;
and
when the sending of the uplink signals does not meet the preset condition, performing power back-off on a power of at least one of the uplink signals of at least one of the plurality of serving cells by multiplying a transmit power of each of the uplink signals having a same priority by a uniform scale factor, the performing the power back-off further comprising:
performing the power back-off on the power of at least one but not all of the uplink signals on a given carrier of the at least one of the plurality of serving cells;
and
performing power back-off of a first amplitude on a serving cell whose priority is less than a priority threshold, and performing power back-off of a second amplitude on a serving cell whose priority is greater than or equal to the priority threshold, wherein the first amplitude is greater than the second amplitude.

4 more elements
