摘要： Embodiments provide systems and methods to optimize the time when to transmit a silencing frame, and hence, improve the overall network throughput and avoid access point transmission rate fall-back mechanism having an avalanche effect during coexistence of dissimilar wireless network technologies. A receiver comprises at least two dissimilar network technology subsystems, at least one subsystem of which is higher priority than at least another of the dissimilar subsystems. In some embodiments, a receiver is able to transmit a silencing frame during a predetermined transmission window within a lower priority technology network interval. In other embodiments, a receiver calculates a predetermined transmission window, the predetermined transmission window to occur within a lower priority technology network interval, and transmits a silencing frame during the predetermined transmission window. In further embodiments, a receiver is able to calculate a transmission window to occur during a lower priority technology network interval, and transmit a silencing frame during the calculated transmission window.

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 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.

摘要： A device comprising transceiver logic and control logic coupled to the transceiver logic. The control logic is adapted to use the transceiver logic to broadcast a signal comprising either a Request-to-Send (RTS) signal or a Clear-to-Send-to-Self (CTS2S) signal to a plurality of other devices. The signal is adapted to cause the plurality of other devices to refrain from transmitting data. After at least some of the plurality of other devices have received the signal, the transceiver logic transmits at least part of another signal using beamforming techniques.

摘要： Embodiments of the invention provide a dynamic priority adjustment algorithm for PS-Poll packets in WLAN and dynamic CW (contention window) management algorithm for PS-Poll packets in WLAN. These improve the performance of traffic flows associated with STAs in power save mode. Maintain the QoS requirements of the traffic flows. When PS-Poll packets are not able to be sent, the QoS STA will experience a long delay of the downlink data, even if the downlink data has been assigned a higher AC. The delay may potentially violate the QoS bound required by the data flow. Using the embodiments can significantly decrease the probability of this event.

摘要： An expanded sequence number is added to PDUs in a Bluetooth® low energy system. The expanded sequence number provides more accurate identification of the PDUs and allows the system to avoid delaying transmission of PDUs while retransmitting other PDUs. A PDU security sequence number may also be added to the PDUs. The security sequence number is used to create a unique nonce for use in encrypting or decrypting and authenticating the PDU. Using the security sequence number, a failed connection can be reestablished between two devices without the need of generating an encryption key. The security sequence number allows the devices to perform encryption or decryption and authentication using an existing key and a nonce generated from the security sequence number.
