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 combination device includes a first wireless transceiver configured for communication via a first wireless network over a first band, and a second wireless transceiver configured for communication via a second wireless network over a second band that overlaps the second band. The combination device includes a medium allocation scheduler coupled to the first wireless transceiver and second wireless transceiver for implementing spaced-mode operation that intentionally inserts idle gaps in transmissions via the second wireless network when triggered by the presence of at least one spaced-mode triggering condition. The idle gaps allow wireless transmissions via the first wireless network to be received by the combination device with higher probability, and without the need for clear to send (C2S) protection.

摘要： A method of communications for a coexisting wireless network including a wireless combination (combo) device communicating via a first wireless network and second wireless network, and a first wireless device on the first network. During an activity interval for the second network (i) a transmit (Tx) time interval is longer in duration than a Tx packet duration and/or (ii) a receive (Rx) time interval is longer in duration than a Rx packet duration to provide remaining time. A frame aggregated packet is used on the first network that includes a plurality of data packets and a dummy packet or spoofing so that the frame aggregated packet is extended in time or indicates an extension sufficient to overlap the Tx time interval or Rx time interval. The combo device transmits or receives an acknowledgement (ACK) on the first network during the activity interval for the second wireless network.

摘要： A network includes an access point using a first protocol and a station using both the first protocol and a second protocol. The station uses the first protocol before a first threshold and a second protocol after the first threshold. A first duration between the second threshold and the first threshold is at least of sufficient length for the station to receive one data packet from the access point and send an acknowledgment. The station transmits to the access point a current clear-to-send packet at a current time during a current exchange based on success or failure of a previous exchange during which a previous clear-to-send packet was transmitted to the access point at a previous time.
