1. A method implemented by a wireless transmit receive unit (WTRU), the method comprising:
- the WTRU receiving a radio resource control (RRC) message, the RRC message comprising a discontinuous reception (DRX) configuration, the DRX configuration comprising an indication of a DRX cycle periodicity and an indication of a length of a DRX minimum active period;
the WTRU receiving a data indication signal during the DRX minimum active period of a DRX cycle, the data indication signal indicating that downlink data is to be sent to the WTRU;
the WTRU receiving the downlink data;
the WTRU receiving a medium access control (MAC) message comprising a DRX activation message; and
the WTRU resuming DRX operation based on receiving the MAC message comprising the DRX activation message.

20. A device comprising a processor and memory, the device configured to:
-
send a radio resource control (RRC) message to a wireless transmit receive unit (WTRU), the RRC message comprising a discontinuous reception (DRX) configuration, the DRX configuration comprising an indication of a DRX cycle periodicity and an indication of a length of a DRX minimum active period; send a data indication signal, the data indication signal indicating that downlink data is to be sent to the WTRU; send the downlink data; and send a medium access control (MAC) message comprising a DRX activation message, the MAC message comprising the DRX activation message indicating indication that the WTRU can resume DRX operation.
