1. A method, comprising:
at a user equipment (UE):
receiving a radio network temporary identifier (RNTI) associated with a group of UEs, the group of UEs including the UE;
processing a signal from one of a cell on which the UE is currently camped or a cell to which the UE is currently connected, wherein the signal is scrambled by the RNTI and includes control information;
processing a radio resource control (RRC) signal from the currently camped or currently connected cell, wherein the RRC signal comprises an indication of at least one of the group of UEs configured to transmit a hybrid automatic repeat request (HARQ) feedback for group-based scheduling;
transmitting HARQ feedback to the one of the currently camped cell or currently connected cell, the HARQ feedback associated with the signal; and
performing an operation in response to the control information included in the signal after being descrambled by the RNTI.
