1. A wireless communication method, comprising:
receiving, by a terminal device, at least one physical downlink control channel (PDCCH) sent by the network device according to a plurality of transmit configuration instruction (TCI) states, wherein the at least one PDCCH is used to schedule a same first channel or a same first signal;
determining, by the terminal device, a TCI state of the first channel or the first signal according to information of first downlink control information (DCI) and at least one time interval,
wherein the first DCI is DCI carried on the at least one PDCCH; the at least one time interval is a time interval between the at least one PDCCH and the first channel or the at least one time interval is a time interval between the at least one PDCCH and the first signal;
wherein the at least one time interval is one time interval, the one time interval is a time interval between one PDCCH among the at least one PDCCH and the first channel or the first signal;
wherein determining, by the terminal device, the TCI state of the first channel or the first signal according to the information of the first DCI and the at least one time interval comprises:
if a format of the DCI is a second format, the DCI does not comprise the TCI state indication, and the one time interval is greater than or equal to a preset threshold, determining, by the terminal device, the TCI state of the first channel or the first signal according to a TCI state of a first CORESET in a first time unit;
wherein determining, by the terminal device, the TCI state of the first channel or the first signal according to the TCI state of the first CORESET in the first time unit comprises:
if there are two TCI states of the first CORESET, determining, by the terminal device, a second TCI state as the TCI state of the first channel or the first signal.
