Embodiment

[0051]CLAIMS 1. A method for controlling discontinuous reception (DRX) in a wireless transmit / receive unit (WTRU), the method comprising defining a plurality of DRX classes, wherein each DRX class includes a respective DRX cycle length.

[0052] 2. The method of embodiment 1, further comprising transitioning between DRX levels based on a set of criteria.

[0053] 3. The method of embodiment 2, wherein the set of criteria is predefined.

[0054] 4. The method of embodiment 2, wherein the set of criteria is based on events detected by the WTRU.

[0055] 5. The method of embodiment 2, wherein the set of criteria is based on an explicit signal received by the WTRU.

[0056] 6. The method of embodiment 2 or 3, wherein the set of criteria is defined dynamically.

[0057] 7. The method as in any one of embodiments 2 to 6, wherein switching between multiple DRX levels is based on learned traffic patterns.

[0058] 8. The method as in any one of embodiments 2 to 6, wherein switching...

Abstract

A method for controlling discontinuous reception in a wireless transmit / receive unit includes defining a plurality of DRX levels, wherein each DRX level includes a respective DRX cycle length and transitioning between DRX levels based on a set of criteria. The transitioning may be triggered by implicit rules.

Description

technical field [0001] The invention relates to the field of wireless communication. Background technique [0002] One goal of the 3rd Generation Partnership Project (3GPP) Long Term Evolution (LTE) project is to develop new technologies, new architectures, and new methods for the setup and deployment of wireless communication systems to improve spectral efficiency, reduce latency, and Make good use of radio resources to bring users faster user experience and richer applications and services at low cost. [0003] In a typical LTE network, a wireless transmit / receive unit (WTRU) may operate in multiple modes, while in LTE_ACTIVE mode, the WTRU may operate in discontinuous reception (DRX) mode. DRX mode allows the WTRU to operate in low power or sleep mode for a preset period of time, then switch to full power or awake mode and operate for another preset period of time to reduce battery consumption. Typically, the DRX cycle length is configured through the Enhanced Universal...
