SYSTEM ENHANCEMENTS FOR USING EXTENDED DRX

摘要

Methods and apparatus may be used for selecting power saving mechanisms in a wireless transmit/receive unit (WTRU). For example, a WTRU may support at least power saving mode (PSM) and/or extended discontinuous reception (eDRX) mode. The WTRU may send a request message including parameters associated with the supported power saving mechanisms, such as an active time for PSM and a preferred DRX value for eDRX mode. The WTRU may receive an accept message including at least one selected parameter indicating the power saving mechanism for the WTRU selected by the network (NW). The WTRU may activate the selected power saving mechanism, and may start a validity timer to define the duration of use of the selected power saving mechanism. In another example, a WTRU configured to use eDRX may receive paging signals for system information (SI) change over a prolonged Broadcast Control Channel (BCCH) modification period.

1. A wireless transmit/receive unit (WTRU) configured to select a power saving mechanism comprising:
a transmitter configured to send a request message, wherein the request message includes a plurality of parameters associated with plurality of power saving mechanisms supported by the WTRU; a receiver configured to receive, from a mobility management entity (MME), an accept message from a including at least one selected parameter associated with at least one selected power saving mechanism, wherein the at least one selected power saving mechanism is from the plurality of power saving mechanisms supported by the WTRU; and a processor configured to activate the at least one selected power saving mechanism.
