1. A method of a User Equipment (UE), comprising:
being configured with a Group Configured Scheduling RNTI (G-CS-RNTI) by a base station, wherein the G-CS-RNTI is used for Semi-Persistent Scheduling (SPS) activation associated with a multicast configured downlink resource;
at least one of receiving or detecting a multicast transmission of downlink data on the multicast configured downlink resource after SPS activation, wherein the multicast transmission is associated with a Hybrid Automatic Repeat Request (HARQ) process;
