Resource monitoring method, terminal, and base station

A terminal, comprising:

• a storage, a processor, and a computer program stored on the storage and executable by the processor, wherein when the computer program is executed by the processor, the processor implements a resource monitoring method, the resource monitoring method comprises:
• receiving Control Resource Set (CORESET) configuration information sent by a base station, wherein the CORESET configuration information indicates a CORESET;
• determining, according to a predefined Transmission Configuration Indication (TCI) state or a first downlink Media Access Control Control Element (MAC CE) sent by the base station, a target TCI state used for monitoring the CORESET;
• monitoring the CORESET according to the target TCI state;
• wherein the first downlink MAC CE is a downlink MAC CE comprising an activated TCI state.
