摘要： Systems and methods for reduction of handover latencies in wireless communication systems are described herein. Some illustrative embodiments include a wireless mobile communication device that includes a wireless transceiver including a transmitter configured to transmit a first signal synchronized for reception by a first cellular node, and processing logic that couples to the wireless transceiver. Before the wireless transceiver receives a handover command the processing logic causes the transmitter to transmit a second signal for reception by a second cellular node to request allocation of an upload resource for communication with the second cellular node as part of an impending handover.

摘要： Methods and apparatus to provide fairness for wireless local area networks that use extended physical layer (a.k.a. PHY) protection mechanisms are disclosed. A disclosed example method comprises choosing a length field value for a frame header such that, when a transmit operation is ended, a legacy wireless station and a non-legacy wireless station of a wireless local area network are able to start contending for a wireless medium at substantially a same instant, and sending a frame across the wireless medium that includes the frame header.

摘要： In accordance with at least some embodiments, a system comprises an access point and a station in communication with the access point. The station has at least two network technology subsystems subject to coexistence interference. The station selectively implements bounded Power Save (PS)-Polling (BPS) logic to handle communications between the station and the access point. The BPS logic operates to confine PS-Poll transmissions starts to one of two separate windows during a medium grant duration of the station.
