1. A signal receiving method, comprising:
receiving downlink control information (DCI) on a first component carrier (CC), wherein the DCI indicates a second CC and a second bandwidth part (BWP) for receving a physical downlink shared channel (PDSCH), the DCI comprises a transmission configuration indication (TCI) field, and the second CC is different from the first CC; and
receiving the PDSCH based on a first transmission configuration indicator (TCI) state configured for the second CC and the second BWP, wherein:
the first TCI state is determined based on a first mapping relationship and a value of the TCI field;
the first mapping relationship is a correspondence between at least one TCI state and at least one TCI field value and is determined based on the second CC and the second BWP.
