Uplink power control method and communication apparatus

The invention relates to the field of radio communications, and specifically, to an uplink power control method and communication apparatus. The uplink power control method comprises: a terminal apparatus receives power control indication information transmitted by a network apparatus and indicative of a first power offset set, wherein the first power offset set is any one of two first power offset sets; the terminal apparatus receives a transmit power control command (TPC) transmitted by the network apparatus and indicative of a first offset in the first power offset set; and the terminal apparatus determines, according to the first offset, uplink transmission power. Since the impact of cross-interference is taken into consideration when determining uplink transmission power, the method can satisfy requirements of communication for future generations, enhancing system performance.
