Abstract: A method and system to improve the link budget of a wireless system using fast Hybrid Automatic Repeat Request (HARQ) protocol. In one embodiment of the invention, the Medium Access Control (MAC) logic in a base station determines whether the quality of the communication link with a mobile station is bad. When the MAC logic in the base station determines that the quality is bad, the base station uses a fast Hybrid Automatic Repeat Request (HARQ) protocol to indicate to the mobile station to send identical information to the base station in each of a plurality of successive or consecutive communication intervals before processing any received identical information from the mobile station. The fast HARQ protocol reduces the latency of receiving the identical information correctly, as compared with the current HARQ protocol.

Abstract: Embodiments of a system and method for wireless communication are provided. In certain embodiments, a base station provides a first zone using a first version of the communication standard and a second zone using a second version of the communication standard. In certain embodiments, the base station determines whether a mobile station communicating with the base station in the first zone can support the second version of the communication standard used in the second zone. When the mobile station can support the second version of the communication standard, the base station can send a command to switch the mobile station to the second zone.

Abstract: Embodiments of methods for optimizing power savings in a wireless device by maintaining sleep in sub-frames of an extended Listen Window, in an I.E.E.E. 802.16m communication system. In one embodiment, the Listen Window is extended into the Sleep Window, wherein at least one sub-frame remains designated for sleep. The power savings may be used when HARQ retransmissions are scheduled or for VoIP transmissions and so forth.

Abstract: A preemption system enables successful transmission of multiple service data units (SDUs) across a wireless interface. The preemption system addresses out-of-order transmissions of fragments of SDUs, such that the receiver is able to process each successfully. The preemption system enables a higher-priority SDU to simultaneously be transmitted with a lower-priority SDU, so that delays in processing the lower-priority SDU does not negatively affect processing of the higher-priority SDU. The preemption system also addresses non-automatic repeat request medium access controller (non-ARQ MAC) connections that only use hybrid automatic repeat request (HARQ), in which the HARQ transmission may cause out-of-order delivery of SDU fragments.

Abstract: A single format of MAC control message may be used for the addition, deletion, or rearrangement of users in a group within a wireless network. In some cases, a change in the nature of the group may be implemented immediately upon receipt of a positive acknowledgement. A mobile station may determine its ACID without maintaining information about the previous ACID or startup frame.
