1. A method for reliability of a physical downlink control channel (PDCCH) in a communication network, the method comprising:
determining a duplication set comprising multiple PDCCH candidates;
receiving one or more PDCCH candidates associated with the duplication set;
decoding one or more duplicated downlink control information (DCI) from the one or more PDCCH candidates;
determining that there is a first user equipment (UE) action indicated by the DCI;
based on the determining that there is the first UE action indicated by the DCI, selecting one or more reference resources; and
performing the first UE action using the reference resource as a time reference for the first UE action.
