1. A wireless transmit/receive unit (WTRU) comprising a processor configured to:
receive a radio resource control (RRC) message, wherein the RRC message comprises an indication of a discontinuous reception (DRX) minimum active period, wherein an active period of a DRX cycle is of variable length and the DRX minimum active period corresponds to a minimum length of the active period of the DRX cycle if no transmissions are sent to the WTRU during the DRX cycle;
monitor for a data indication signal during the DRX minimum active period of the DRX cycle;
remain awake beyond the minimum active period of the DRX cycle based on receiving the data indication signal during the DRX minimum active period of the DRX cycle, wherein the data indication signal comprises an indication of a time when a data transmission will start and when the data transmission will end; and
receive the data transmission in accordance with the data indication signal.
