1. A user equipment (UE) in a communication system, the UE comprising:
a processor; and
a transceiver operably coupled to the processor, the transceiver configured to
receive group indexes for search space set groups including a first search space set group and a second search space set group, and
receive downlink control information (DCI) including a field of 2 bits,
wherein in case that the field is a first value or a second value, the field indicates a search space set group among the search space set groups for physical downlink control channel (PDCCH) monitoring,
wherein in case that the field is a third value, the field indicates skipping the PDCCH monitoring for a first configured time duration,
wherein in case that the field is a fourth value, the field indicates skipping the PDCCH monitoring for a second configured time duration,
wherein in case that the field is the first value, the field indicates performing the PDCCH monitoring according to the first search space set group,
wherein in case that the field is the second value, the field indicates performing the PDCCH monitoring according to the second search space set group,
wherein the transceiver is further configured to receive a third configuration of a timer associated with the search space set groups, and
wherein the processor is further configured to:
decrement the timer by one after each slot, and
perform the PDCCH monitoring according to the first search space set group after the timer is expired.
