摘要： In at least some embodiments, a communication device includes a host processor and a plurality of co-existing wireless technology transceivers coupled to the host processor. The plurality of co-existing wireless technology transceivers share a communication medium using time-multiplexing. A throughput for data transmissions by the plurality of co-existing wireless technology transceivers is based on an algorithm that determines a grouping option for data packets to be transmitted by one of the co-existing wireless technology transceivers, the grouping option providing a highest throughput for a predetermined baseband PHY rate without exceeding a predetermined maximum grouping delay.

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 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.

摘要： A system and method for arbitrating channel access in a wireless device including co-located network transceivers are disclosed herein. A wireless device includes a first wireless transceiver and a second wireless transceiver. The first transceiver is configured for operation with a first wireless network. The second transceiver is configured for operation with a second wireless network. The wireless device further includes logic that determines which of the first and second transceivers is enabled to transmit at a given time. The logic causes the first transceiver to transmit a notification signal indicating a time period during which the second transceiver of the wireless device will perform a first wireless transaction, and during which, based on receiving the notification signal, a different wireless device performs a second wireless transaction via the second wireless network without transmitting a notification signal.

摘要： A system and method for using partially received packets in coexisting networks. In one embodiment, a wireless receiver includes an interference detector and a packet validator. The interference detector is configured to determine that time multiplexing of a coexisting wireless network interferes with reception of a packet by the wireless receiver. The packet validator is configured to identify a type of the packet and useable data values of the packet when a partial packet is received due to the time multiplexing. The packet validator is configured to identify the type and useable data values of the packet based on a packet signature stored in the wireless receiver.
