Claim:
1. A wireless communication method, comprising: receiving a first TPC-radio network temporary identifier (TPC-RNTI), a second TPC-RNTI, and first indication information that are sent by the base station, wherein the first indication information is used to indicate that: a first PDCCH that is scrambled by the first TPC-RNTI and whose format is the DCI format 3/3A is used to carry a first TPC command; and a second PDCCH that is scrambled by the second TPC-RNTI and whose format is the DCI format 3/3A is used to carry a second TPC command; receiving, in the fixed downlink subframe whose subframe number is i−K i−K wherein the at least one TPC command is carried on a physical downlink control channel (PDCCH) in a downlink control information format (DCI format) 3/3A, and the at least one TPC command comprises a TPC command from an uplink signal that is sent in an uplink subframe whose subframe number is i; determining, according to the TPC command of the uplink signal that is sent in the uplink subframe whose subframe number is i, the transmit power of the uplink signal that is sent in the uplink subframe whose subframe number is i, wherein the uplink subframe whose subframe number is i is the (K sending, according to the transmit power, the uplink signal in the subframe whose subframe number is i, wherein different TPC commands are used to indicate transmit power of uplink signals that are sent in different uplink subframes, and the uplink signal is a physical uplink shared channel (PUSCH) or a sounding reference signal (SRS).
