1. A beam indication method, comprising:
receiving Transmission Configuration Indication (TCI) indication of a target control resource set issued by a base station; and
updating beam information of a target Physical Downlink Shared Channel (PDSCH) and a target Physical Uplink Control Channel (PUCCH) scheduled by the target control resource set, wherein a Quasi Co-Located (QCL)-type D Reference Signal (RS) in the TCI indication of the target control resource set serves as a spatial domain filter RS corresponding to the target PDSCH and the target PUCCH;
wherein prior to updating the beam information of the target PDSCH and the target PUCCH scheduled by the target control resource set, the method further comprises: determining that a target high-layer signaling is received from the base station;
wherein the target high-layer signaling is an enableuniversalbeam signaling, the beam information of the uplink channel and the beam information of the downlink channel are updated in linkage in response to the enableuniversalbeam signaling being set to be true, or the beam information of the uplink channel and the beam information of the downlink channel are not updated in linkage simultaneously in response to the enableuniversalbeam signaling being set to be false.
