1. A method implemented by a wireless transmit/receive unit (WTRU), the method comprising:
receiving discontinuous reception (DRX) configuration information in a radio resource control (RRC) message, the DRX configuration information comprising an indication of a first DRX cycle periodicity and an indication of a second DRX cycle periodicity;
receiving a first medium access control (MAC) message during a first DRX active period, the first MAC message indicating that the WTRU is to resume DRX using the first DRX cycle periodicity;
performing DRX in accordance with the first DRX cycle periodicity based on receiving the first MAC message;
receiving a second MAC message during a second DRX active period, the second MAC message indicating that the WTRU is to resume DRX using the second DRX cycle periodicity; and
performing DRX in accordance with the second DRX cycle periodicity based on receiving the second MAC message.
