1. A method for conserving power of a wireless transmit/receive unit (WTRU), the method comprising:
- receiving a queue identifying packets that are intended for the WTRU;
wherein the queue includes information regarding a location of packets in the queue waiting for transmission to the WTRU in a scheduled transmission;
entering into an OFF mode when the information included in the queue indicates a delay time above a predetermined threshold, wherein the delay time is based on the location of packets in the queue waiting for transmission;
entering an AWAKE mode upon expiration of the delay time; and
receiving the packets at the WTRU.

Abstract
Method and system for reducing battery consumption during an active session wherein an access point (AP) transmits a wireless transmit/receive unit (WTRU) a packet information regarding packets in a queue waiting for transmission to the WTRU and when the packets are to be decoded, whereby enabling the WTRU to enter or remain in an OFF mode in accordance with the packet information. The AP does not send the packets to the WTRU until the AP informs the WTRU about the packet.

15. A power efficient wireless transmit/receive unit (WTRU) comprising:
-
a receiver configured to receive a queue identifying packets that are intended for the WTRU;
wherein the queue includes information regarding a location of packets in the queue waiting for transmission to the WTRU in a scheduled transmission; anda processor configured to place a component of the WTRU into an OFF mode when the information included in the queue indicates a delay time above a predetermined threshold, wherein the delay time is based on the location of packets in the queue waiting for transmission, and to place a component of the WTRU in an AWAKE mode upon expiration of the delay time; wherein the receiver is further configured to receive the packets when in an AWAKE mode. - View Dependent Claims (16, 17, 18, 19, 20, 21, 22, 23, 24, 25, 26)
