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.

Claims (29)

1 . A method implemented by a wireless transmit/receive unit (WTRU), the method comprising:

receiving a radio resource control (RRC) message, the RRC message comprising an indication of a discontinuous reception (DRX) minimum active period; and

receiving a medium access control (MAC) message during a DRX active period, the MAC message indicating that the WTRU is allowed to enter a sleep period until the DRX minimum active period of a subsequent DRX cycle.

2 . The method of claim 1 , wherein the RRC message comprises an indication of a DRX cycle periodicity.

3 . The method of claim 1 , wherein the MAC message corresponds to a DRX activation message.

4 . The method of claim 1 , wherein the MAC message indicates that the WTRU can resume DRX.

5 . The method of claim 1 , further comprising:

receiving a data indication signal during the DRX active period.

6 . The method of claim 5 , wherein the data indication signal indicates a start and length of a data transmission.

7 . The method of claim 5 , wherein the MAC message is received after the data indication signal.

8 . A wireless transmit/receive unit (WTRU) configured to:

receive a radio resource control (RRC) message, the RRC message comprising an indication of a discontinuous reception (DRX) minimum active period; and

receive a medium access control (MAC) message during a DRX active period, the MAC message indicating that the WTRU is allowed to enter a sleep period until the DRX minimum active period of a subsequent DRX cycle.

9 . The WTRU of claim 8 , wherein the RRC message comprises an indication of a DRX cycle periodicity.

10 . The WTRU of claim 8 , wherein the MAC message corresponds to a DRX activation message.

11 . The WTRU of claim 8 , wherein the MAC message indicates that the WTRU can resume DRX.

12 . The WTRU of claim 8 , wherein the WTRU is configured to:

receive a data indication signal during the DRX active period.

13 . The WTRU of claim 12 , wherein the data indication signal indicates a start and length of a data transmission.

14 . The WTRU of claim 8 , wherein the MAC message is received after the data indication signal.

15 . A wireless transmit/receive unit (WTRU) configured to:

receive a radio resource control (RRC) message, the RRC message comprising an indication of a discontinuous reception (DRX) minimum active period; and

receive a medium access control (MAC) message during a DRX active period, the MAC message indicating an end of the DRX active period.

16 . The WTRU of claim 15 , wherein the RRC message comprises an indication of a DRX cycle periodicity.

17 . The WTRU of claim 15 , wherein the MAC message corresponds to a DRX activation message.

18 . The WTRU of claim 8 , wherein the WTRU is configured to:

receive a data indication signal during the DRX active period.

19 . The WTRU of claim 18 , wherein the data indication signal indicates a start and length of a data transmission.

20 . The WTRU of claim 18 , wherein the MAC message is received after the data indication signal.
