Disclosed is an uplink power control method, which is used for realizing power control over uplink channels with different uplink transmission times so as to ensure that the total transmit power of terminal equipment in a sub-frame does not exceed maximum transmit power and that a system can work normally. The method comprises the following steps: the terminal equipment determines the target transmit power of each uplink channel/signal transmitted in a current uplink sub-frame; the terminal equipment divides the transmission time of the uplink channels/signals in the current uplink sub-frame into a plurality of transmission time buckets, wherein the uplink channels/signals at any moment in each transmission time bucket are the same, and the uplink channels/signals in each transmission time bucket are not exactly the same as those in the other transmission time buckets; and in each transmission time bucket, the terminal equipment performs the power control on the target transmit power of the uplink channels/signals transmitted in the transmission time bucket to ensure that the transmit power sum of the uplink channels/signals transmitted in the transmission time bucket does not exceed the preset maximum transmit power of the terminal equipment after the power control. Also disclosed a device for implementing the method. |
