1. IL198293 - METHOD AND APPARATUS FOR ENHANCING DISCONTINUOUS RECEPTION IN WIRELESS SYSTEMS

Note: Texte fondé sur des processus automatiques de reconnaissance optique de caractères. Seule la version PDF a une valeur juridique

What is claimed is:

1. A method of discontinuous reception (DRX) in a wireless transmit receive unit (WTRU), the method comprising: - the WTRU receiving DRX Betting information over a radio resource control (RRC) signal; and

the WTRU receiving DRX activation information over medium access control (MAC), signal.

2. The . method as in claim 1 further comprising grouping DRX setting information into a DRX profile.

3. The method as in claim 2 further comprising determining a DRX profile index associated with the DRX profile.

4. The method as in claim 3 further comprising the WTRU receiving the DRX profile over RRC signaling.

5. A method of discontinuous reception (DRX). in a wireless communication system, the method comprising:

a wireless transmit receive unit (WTRU) in a DRX minimum active period receiving a data indication signal from an e Node-B (eNB); and

the WTRU remaining in an active period based on the data indication signal. .

6. The method as in claim 5 further comprising:

the WTRU discontinuing DRX operation based on the data indication signal; and

the WTRU resumin DRX operation based on a received signal from an eNB after data reception.

7. The method as in claim 5 further comprising the TRU transmitting a signal to the eNB, wherein the signal comprises a request to enter DRX mode.

8. The method as in claim 7 further comprising the WTRU transmitting the signal to the eNB based on a trigger.

9. The method as in claim 7 further comprising the eNB responding to the signal with a second signal, wherein the second signal comprises DRX settings information.

10. The method as in claim 5 wherein the data indication signal comprises a DRX start time.

11. The method as in claim 5 wherein the data indication signal comprises a DRX cycle time, a DRX minimum activation time, and a DRX start time.

12. The method as in claim 5 further comprising:

the WTRU discontinuing DRX operation based on the data indication signal; and

the WTRU resuming DRX operation at a start of a regular DRX cycle.

13. The method as in claim 5 wherein the data indication signal comprises a data transmission start time and an indication of a temporal length of the data transmission.

14. A method of discontinuous reception and discontinuous transmission, the method comprising:

coordinating the DRX cycle of a wireless transmit receive unit (WTRU) and a discontinuous transmission (DTX) cycle of an e-node B such that the DRX and DTX cycles coincide; and

setting a DRX measurement cycle of the WTRU dependent on a distance of the WTRU from a cell edge.

15. Cancelled.

16. The method as in claim 14 further comprising the WTRU discontinuing DRX mode based on a serving cell strength falling below a threshold.

17. The method as in claim 14 further comprising determining a separate DRX cycle for certain services, wherein the certain services comprise voice-over-D? (VOIP) and web browsing.

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

receive discontinuous reception (DRX) setting information in a radio resource control (RRC) signal; and

receive DRX activation information in a medium access control (MAC) signal.

19. The WTRU as in claim 18 wherein the WTRU is further configured to:

receive a data indication signal from an e Node-B (eNB) while the WTRU is in a DRX minimum active period; and

remain in an active period based on the data indication signal.

The WTRU as in claim 18 wherein the WTRU is further configured to: discontinue DRX operation based on the data indication signal; and

resume DRX operation based on a received signal from

after data reception.

21. The WTRU aa in claim 18 wherein the WTRU is further configured to transmit a signal to the eNB, wherein the signal comprises a request to enter DKX mode.

22. The WTRU as in claim 21 wherein the WTRU is further configured to transmit the signal to the eNB based on a trigger.

23. The WTRU as in claim 18 wherein the WTRU is further configured to:

discontinue DKX operation based on the data indication signal;' and

resume DRX operation at a start of a regular DRX cycle.

24. The WTRU as in claim 18 wherein the WTRU is further configured to:

measure an inactivity time following reception of data; and determine DRX operation start based on the inactivity time.

26. The WTRU as in claim 18 wherein the WTRU is further configured to:

remain in DRX operation for a minimum active period.
