1. A method for performing search space set switching, the method comprising:
by a wireless communication apparatus:
monitoring a first search space set group for physical downlink control channel (PDCCH) transmissions, wherein the first search space set group includes at least a first search space with a first monitoring configuration;
receiving a downlink control indicator (DCI) Format 2_0 message, wherein the DCI Format 2_0 message includes an indication for the wireless communication apparatus to switch to monitoring a second search space set group, wherein monitoring the second search space set group comprises monitoring a second search space with a second monitoring configuration including monitoring the second search space in a set of Y slots of each group of a series of multi-slot groups of either X=4 or X=8 slots;
in response to the indication, switching to start monitoring the second search space set group and stop monitoring the first search space set group at a start of a next full multi-slot group of X slots for the second search space that is at least P symbols from a last symbol of a PDCCH transmission corresponding to the DCI Format 2_0 message, wherein the P symbols is a predetermined time.
