1. An apparatus for wireless communication at a user equipment (UE), comprising:
at least one processor; and
at least one memory coupled with the at least one processor, with instructions stored in the at least one memory, the instructions being executable by the at least one processor, individually or in any combination, to cause the apparatus to:
receive, from a base station and at the UE of a group of UEs, control signaling indicating a link between a first search space set and a second search space set used for a multicast broadcast service, wherein a first downlink control channel for the group of UEs is transmitted in the first search space set and a second downlink control channel is transmitted in the second search space set, and wherein the link indicates that at least one parameter associated with the second search space set is the same as at least one parameter associated with the first search space set;
monitor the first search space set for a first instance of control information in the first downlink control channel and the second search space set for a second instance of the control information in the second downlink control channel; and
decode the first instance or the second instance of the control information, or both, based at least in part on the monitoring.
