Abstract: Methods and apparatuses enable providing a dynamic, adaptive discontinuous reception (DRX) period based on available battery power of a mobile device. A mobile device can be assigned a DRX period based on a battery power level of the mobile device, and the assigned DRX period can be dynamically changed to reflect changes to the battery power level. In one embodiment, the mobile device initiates changes to the DRX period.

Abstract: An embodiment of the present invention provides a method, comprising, enhancing persistent scheduling with efficient link adaptation capability by grouping Voice over internet Protocol (VoIP) users and using an intelligent bitmap mechanism to compactly represent persistent allocations for the users within the group.

Abstract: Briefly, in accordance with one or more embodiments, a MAP may be used by a base station to allocate network users for one or more users in a wireless network using persistent scheduling. In the event one or more of the users does not successfully receive a MAP transmitted by the base station, the user may stop transmitting and/or receiving in order to minimize and/or avoid collision with transmissions from other users. The affected user may transmit an indication of the error in receiving the MAP to the base station, wherein the base station may retransmit the previously transmitted MAP to the affected user that did not successfully receive the MAP from the origination transmission.

In the event one or more of the users does not successfully receive a MAP transmitted by the base station, the user may stop transmitting and/or receiving in order to minimize and/or avoid collision with transmissions from other users. The affected user may transmit an indication of the error in receiving the MAP to the base station, wherein the base station may retransmit the previously transmitted MAP to the affected user that did not successfully receive the MAP from the origination transmission. One or more users may utilize a shared NAK channel to indicate to the base station an indication of the error in receive the MAP.

Abstract: Briefly, in accordance with one or more embodiments, HARQ retransmissions may be persistently scheduled so as to efficiently allocate network without requiring the HARQ retransmissions to be scheduled for every frame or nearly every frame. Furthermore, grouping of users may occur using a bitmap for the HARQ retransmissions using the same bitmap as used for scheduling of the original packet transmission or using a separate bitmap for the HARQ retransmissions. In the event one or more scheduled HARQ retransmissions are not needed, the base station is capable of reallocating the previously scheduled resources.

Abstract: Various embodiments of the invention may take advantage of persistent scheduling in a wireless network to achieve efficiencies of operation. One embodiment dynamically adjusts the duration of persistent scheduling based on changing channel conditions. When mobile stations are grouped together for persistent scheduling, another embodiment uses a bitmap to indicate which mobile stations in the group have data in the current frame. Still another embodiment eliminates the Connection Identifier from a packet header when bitmaps are being used.

Abstract: Methods and apparatuses enable sending a fast access request in a preamble of a random access request. The fast access request provides for an uplink assignment having bandwidth sufficient to allow the transmission of data with a scheduling request. The fast access request can indicate, for example, a traffic class of a message to be sent. Based on traffic class information, up to a certain additional amount of bandwidth can be allocated for a scheduling procedure for the requesting user device.
