SYSTEM ENHANCEMENTS FOR USING EXTENDED DRX

Abstract

method and apparatus may be used in a wireless transmit/receive unit (WTRU) selects power save mechanism. For example the WTRU may at least supports the power saving mode (PSM) and/or discontinuous reception extension (eDRX) mode. request message (the preferred DRX value of parameters such as activation time of PSM and eDRX mode) the WTRU may send comprises the supporting power save mechanism is associated. WTRU can receive comprises an indication for WTRU power selected by the network (NW) of the saving mechanism of the at least one selected parameter of the received message. The WTRU may activate the selected power save mechanism and can start validity timer to limit use of the selected power saving duration of the mechanism. In another example the WTRU can be configured to use eDRX on the extension of the broadcast control channel (BCCH) modification period to receive system information (SI) change of the paging signal.

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.
