1. A base station for supporting multicast services in a wireless network, comprising:
a processor configured with processor-executable instructions to perform operations comprising:
determining a multicast bandwidth part (BWP) within a carrier bandwidth;
sending an indication of the multicast BWP to one or more user equipments (UEs) in communication with the base station, wherein the multicast BWP is a common frequency bandwidth resource configured to be used by at least a portion of the one or more UEs in communication with the base station;
scheduling transmission of multicast data in the multicast BWP; and
for each of the one or more UEs:
determining whether the common frequency bandwidth resource BWP has a same subcarrier spacing (SCS) and cyclic prefix (CP) length as a UE-specific BWP and the common frequency bandwidth resource is fully contained within the UE-specific BWP; and
sending an indication of a search space set for multicast to the respective UE in response to determining that the common frequency bandwidth resource has a same SCS and CP length as the UE-specific BWP and the common frequency bandwidth resource is fully contained within the UE-specific BWP.
