1. A user equipment (UE) for wireless communication, comprising:
one or more memories; and
one or more processors, coupled to the one or more memories, configured to:
receive, from a base station, radio resource control (RRC) signaling indicating one or more parameters related to a bit size of multicast downlink control information (DCI);
receive, from the base station, a multicast DCI message that includes a set of fields to indicate a set of communication parameters; and
interpret the multicast DCI message that indicates the set of communication parameters based at least in part on a number of padding bits in the multicast DCI message, wherein the number of padding bits is based at least in part on the one or more parameters related to the bit size of the multicast DCI.
