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： An integrated circuit includes logic configured to determine a communication schedule of a device configured to perform Wi-Fi communications in a first Basic Service Set (BSS) network and in a second BSS network. The logic determines the communication schedule based at least in part on a first BSS network communication load of the device and on a second BSS network communication load of the device. The communication schedule defines the service time allocation of the device in the first BSS network and the service time allocation of the device in the second BSS network. At least one of the first and the second BSS networks is supportive of a peer-to-peer connection.
