Optionally, in performing the second power control operation, the at least one second identification is at least one identification corresponding to uplink signal transmissions at a same transmit occasion, and a sum of preset transmit powers corresponding to the at least one second identification is greater than or equal to a maximum transmit power allowed by the terminal.
Optionally, when the second power control operation includes selecting at least one first target identification from at least one second identification for uplink signal transmission based on power priorities of uplink transmissions, no uplink signal transmission is performed for a third target identification at the transmit occasion, where the third target identification is an identification other than the at least one first target identification in the at least one second identification.
Optionally, the at least one first target identification are the first n identifications of the at least one second identification that are arranged according to a rule for prioritizing uplink signal transmissions, and n is a positive integer.
Optionally, the rule for prioritizing uplink signal transmissions includes at least one of the following:
