Abstract: 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.

Abstract: A system comprises radio circuitry, an access point (AP) feature, and a station (STA) feature. The AP feature causes the radio circuitry to transmit data to a hardware device during a beacon interval. The AP feature is not used to receive data from the hardware device during the beacon interval except to receive data request signals. The STA feature causes the radio circuitry to receive data from the hardware device during the beacon interval. The STA feature is not used to transmit data to the hardware device during the beacon interval except to transmit data request signals. The radio circuitry is in a de-powered state during the beacon interval when the radio circuitry does not transmit or receive data or data request signals.

Abstract: Disclosed implementations address the coexistence problem of wireless local area network (WLAN) and Bluetooth Low Energy (BLE) technologies on the same device. For example, an apparatus includes a WLAN controller configured to cause a wireless transceiver module to send and receive packets over a wireless medium. A second controller is coupled to the WLAN controller and also configured to cause the wireless transceiver module to send and receive packet. The second controller informs the WLAN controller that the second controller is going to cause an advertising packet to be transmitted by the wireless transceiver module. The WLAN controller responds by causing a first protection packet to be transmitted by the wireless transceiver module, said first protection packet causes all wireless devices receiving the protection packet to inhibit use of the wireless medium during a timer period which includes the advertising packet. Other embodiments are disclosed as well.

Abstract: 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.
