1. A power control method, comprising:
determining an effective transmit power control (TPC) command window according to a preset physical downlink control channel (PDCCH) in a plurality of repeatedly transmitted PDCCHs, wherein the preset PDCCH comprises a last PDCCH in the plurality of PDCCHs;
determining a closed-loop power adjustment state according to a TPC command in the effective TPC command window; and
determining a transmit power of an uplink signal of a terminal device according to the closed-loop power adjustment state,
wherein the plurality of repeatedly transmitted PDCCHs comprises:
a first PDCCH used for scheduling the uplink signal, and
a repeatedly transmitted second PDCCH used for scheduling a same type of uplink signal most recently before the first PDCCH used for scheduling the uplink signal, wherein a last PDCCH in the repeatedly transmitted second PDCCH is transmitted before the first PDCCH, and
wherein determining the effective TPC command window according to the preset PDCCH in the plurality of repeatedly transmitted PDCCHs comprises:
determining a window between a first OFDM symbol after the last PDCCH in the repeatedly transmitted second PDCCH and a last OFDM symbol of the first PDCCH as the effective TPC command window.
