摘要:
Methods and apparatus for waking a mobile station (MS) from a power saving mode to receive a media access control (MAC) management message (e.g., DCD/UCD, MOB_NBR-ADV, and SII-ADV) the MS has not yet received. The MS may wake from the power saving mode after detecting a mismatch between a set of media access control (MAC) management message parameters last received by the MS and the information found in an enhanced broadcast control pointer information element (BCP-IE) transmitted in a downlink map (DL-MAP). In this manner, the MS may be prevented from waking up unnecessarily, thereby providing high power efficiency.
