Abstract
A method of discontinuous reception (DRX) in a wireless transmit receive unit (WTRU) includes the WTRU receiving DRX setting information over a radio resource control (RRC) signal, and the WTRU receiving DRX activation information over medium access control (MAC) signal.
Claims20
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.

A wireless transmit/receive unit (WTRU) comprising a processor and memory, the processor and memory configured to:
- receive 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 indication of a second DRX cycle periodicity;
- receive 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 first DRX cycle periodicity;
- perform DRX in accordance with the first DRX cycle periodicity based on receiving the first MAC message;
- receive 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
- perform DRX in accordance with the second DRX cycle periodicity based on receiving the second MAC message.

A base station comprising a processor and memory, the processor and memory configured to:
- send a radio resource control (RRC) message to a wireless transmit/receive unit (WTRU), the RRC message comprising discontinuous reception (DRX) configuration information, the DRX configuration information comprising an indication of a first DRX cycle periodicity and indication of a second DRX cycle periodicity;
- send a first medium access control (MAC) message to the WTRU when the WTRU is in a first DRX active period, the first MAC message indicating that the WTRU is to resume DRX using the first DRX cycle periodicity;
- and
- send a second MAC message to the WTRU when the WTRU is in a second DRX active period, the second MAC message indicating that the WTRU is to resume DRX using the second DRX cycle periodicity.
