摘要： Methods and systems are provided for overload control in a wireless communication system. An overload control mechanism identifies an instance of use to eliminate from among a plurality of instances of use in a wireless coverage area. In an overload situation, the overload control mechanism may, for each instance of use, determine a respective ratio of the value of instance of use to the quantity of resource consumed by the instance of use. The overload control mechanism may then sort the instances of use in order of determined ratios to produce a sorted order of the instances of use. The overload control mechanism may select as many instances of use as possible, such that the total amount of resources consumed by the selected instances of use is as high as possible without exceeding the threshold load, and then the overload control mechanism may eliminate the remaining instances of use.

摘要： Systems and methods for performing handover cancellation in a wireless communication system are provided. According to an aspect of the invention, a mobile station requests bandwidth from a serving base station for the mobile station to send a handover cancellation request message to the serving base station. The mobile station then receives an allocation of the requested bandwidth from the serving base station, and sends the handover cancellation request message to the serving base station via the allocated bandwidth. The mobile station requests the bandwidth after a disconnect time and before a resource retain time.

摘要： An apparatus and method of configuring a number of retransmissions for an automatic repeat request (ARQ) scheme (e.g., hybrid ARQ) includes configuring one or more first maximum retransmission numbers based on respective one or more first predetermined values and independent of a second maximum retransmission number. The first maximum retransmission numbers may indicate a maximum number of retransmissions related to respective service flows operational with the base station. The second maximum retransmission number may indicate a maximum number of retransmissions related to control messages transmitted in the wireless network, and may be configured based on a second predetermined value. The configuration of the first maximum retransmission numbers may include the maximum retransmissions numbers associated with a specific user in communication with the base station. Further, at least one of the first maximum retransmission numbers of a particular user may be reconfigured to a third predetermined value.

摘要： A system and method of increasing data throughput in a wireless communications network between a base station (BS) and one or more mobile stations (MS) includes establishing a service flow (SF) and initially enabling a hybrid automated repeat request (HARQ) protocol; determining, at a particular time, the measure of quality of the communications channel; comparing the determined measure of quality with a predetermined channel quality threshold; and selectively disabling the HARQ protocol based upon a first comparison result while continuing the SF between the BS and MS. In other aspects, after selectively disabling the HARQ protocol, the method further includes determining that the time-varying measure of quality of the communications channel has deteriorated below the predetermined channel quality threshold; and selectively re-enabling the HARQ protocol in the established SF.

摘要： Systems and methods for dual wireless communication technology communications are provided. A mobile station communicates with two transceivers of a base site, where each transceiver operates according to a different wireless communication technology. The mobile station can communicate uplink and downlink control information with a first transceiver of the base site while also communicating uplink and downlink data with a second transceiver. Alternatively, the mobile station may transmit uplink transmissions only to a first transceiver and only receive downlink transmissions from a second transceiver.

摘要： A method of operating a communication system comprises sending a frame by an access node to a wireless device where the frame comprises a packet. A counter is initialized and a timer for each frame is initiated. The method continues with the access node determining if a response associated with the packet is received before the expiration of the timer. If the response is received prior to the expiration of the timer, the counter and the timer are reset. If a response is not received prior to the expiration of the timer, the counter is incremented. Upon the counter meeting a criteria of a certain quantity of lost packets, the access node performs a synchronization process.
