摘要： A system and method for reducing power consumption of a wireless device operating as a soft access point. In one embodiment, a wireless device includes a soft access point controller that configures the wireless device to operate as a group owner in a peer-to-peer wireless local area network. The soft access point controller includes a beacon controller. The beacon controller is configured to transmit beacon frames at a first periodic interval. The beacon controller is also configured to extend a discovery interval of a wireless station by transmitting acknowledgement packets at a second periodic interval. The second periodic interval is shorter than the first periodic interval and shorter than a minimum discovery scan timeout of the wireless station.

摘要： A system and method for using reserved resources in coexisting wireless networks. In one embodiment, a wireless apparatus includes a receiver, a network activity monitor, and a network access scheduler. The receiver is configured to identify a received network reservation message that inhibits access to a first wireless network for an interval defined in the reservation message. The network activity monitor is configured to monitor wireless activity on the first wireless network during the interval. The network access scheduler is configured to determine whether the reservation message prevents conflict of the first wireless network with a coexisting wireless network during the interval, and to schedule, based on a determination that the reservation message prevents conflict with the coexisting wireless network, the wireless apparatus to transmit on the first wireless network during the interval to a wireless device other than a wireless device identified in the reservation message.

摘要： A wireless device comprises a first wireless transceiver configured for communication via a first wireless network, a second wireless transceiver configured for communication via a second wireless network; and a scheduler that controls which of the first and second transceivers is granted access to a wireless medium at a given time. When the first wireless transceiver has been granted access to the wireless medium by the scheduler and the first wireless transceiver receives a packet via the first wireless network, the scheduler temporarily grants the second wireless transceiver access to the wireless medium based on the packet indicating that first wireless transceiver is not to use the wireless medium for a period of time.
