1. A method for wireless communications, comprising:
receiving first indication information on a first component carrier (CC), wherein the first indication information indicates a bandwidth part (BWP) for transmitting a downlink signal and a second CC to which the BWP belongs;
determining a first mapping relationship based on the second CC and the BWP, wherein the first mapping relationship indicates a one-to-one correspondence between at least one transmission configuration indicator (TCI) state and at least one TCI value;
determining a TCI state based on the first mapping relationship and a received TCI value;
determining, based on the TCI state, a receive beam for receiving the downlink signal; and
receiving the downlink signal in the BWP on the second CC by using the receive beam.
