摘要： A wireless apparatus includes a wireless transceiver, a WLAN controller and a second controller coupled to the wireless transceiver. The WLAN controller is configured to send/receive packets in accordance with a WLAN protocol, and the second controller is configured to send/receive packets in accordance with a second wireless protocol. The apparatus includes scheduling logic that determines whether a WLAN communication will complete before an end of a WLAN active time period. If the scheduling logic determines that the WLAN communication will not complete before the end of the WLAN active time period, the scheduling logic causes the WLAN controller to transmit a WLAN packet that encodes a NAV value that prevents an access point from using the wireless medium until an end of second time period. The second controller is configured to use the wireless medium during the second time period.

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 includes a peer-to-peer group owner processor that handles peer-to-peer transactions, a memory coupled to the peer-to-peer group owner processor, and a power state controller. The power state controller determines an access category of a communication received from a peer-to-peer client and determines a quality of service constraint for the access category. The power state controller also determines a power-save mechanism for the wireless device based on the quality of service constraint and implements the determined power-save mechanism.

摘要： Various techniques for connection setup for Bluetooth Low Energy (BLE) devices are disclosed. The various embodiments save power. In one example, an apparatus (such as a BLE slave) includes a controller configured to transmit advertising packets and, based on responses to the packets, and lack thereof, the controller estimates the length of the scan window and scan interval. In another embodiment, an apparatus such as a master device is configured to generate a scan update packet that specifies the scan window length, scan interval, and start and end times for that master. The controller is configured to transmit the packet to one or more slave devices.

摘要： A method for operating a wireless transmitter and a global navigation satellite (“GNSS”) receiver coexistent in a mobile wireless device. A mobile wireless device includes a GNSS receiver and a wireless networking system. The wireless networking system includes a wireless transmitter. The wireless transmitter provides a first interference level signal to the GNSS receiver. The first interference level signal indicates a level of interference that the GNSS receiver can expect due to operation of the transmitter. A priority signal is asserted if the processing of navigation signals in the GNSS receiver takes precedence over wireless transmitter transmissions.
