摘要： A system and method for protecting a wireless device including co-located network transceivers from uplink starvation are disclosed herein. A wireless device includes a first wireless transceiver and a second wireless transceiver respectively configured for communication via a first wireless network and a second wireless network. The wireless device further includes logic that determines which of the first and second transceivers is enabled to transmit at a given time. The logic determines a duration of a pending transmission via the first transceiver, and determines a predicted start time of a predicted transmission via the second transceiver. Based on the duration and the predicted start time, the logic transmits a notification signal indicating that a receiving device should refrain from transmitting on the first network for a reserved time ending after the pending transmission starts. The pending transmission starts following completion of the predicted transmission.

摘要： Embodiments of the invention comprise a system and method for estimating a traffic load on a wireless network. An access point notifies a station that the access point will not receive transmissions during a first quiet period. After the first quiet period, the access point monitors the wireless network during a first monitoring period. If no transmissions are received during the first monitoring period, the access point notifies the station that it will not receive transmissions during a second quiet period. The second quiet period has an equal or longer duration than the first quiet period. The access point alternates between monitoring periods and quiet periods and progressively expands the duration of the quiet periods as long as no transmissions are received during the monitoring periods. If a station notifies the access point that packets are pending at the device, the monitoring period is extended to handle these packets immediately.
摘要翻译：本发明的实施例包括用于估计无线网络上的业务负载的系统和方法。接入点通知站点在第一安静期间接入点将不接收传输。在第一个安静时段之后，接入点在第一个监控期间监视无线网络。如果在第一监视期间没有接收到传输，则接入点通知站在第二安静期期间不接收传输。第二个安静的时期与第一个安静的时期相同或更长。接入点在监视周期和安静时段之间交替，并且只要在监视周期内没有接收到传输，则逐渐扩展安静时段的持续时间。如果站点通知接入点设备上的数据包处于待处理状态，则监视周期将被延长以立即处理这些数据包。

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.

摘要： A wireless device comprises a first wireless transceiver configured for communication via a first wireless network, a second wireless transceiver configured for communication via a second wireless network; and a scheduler that controls which of the first and second transceivers is granted access to a wireless medium at a given time. When the first wireless transceiver has been granted access to the wireless medium by the scheduler and the first wireless transceiver receives a packet via the first wireless network, the scheduler temporarily grants the second wireless transceiver access to the wireless medium based on the packet indicating that first wireless transceiver is not to use the wireless medium for a period of time.

摘要： A system and method for reducing power consumption of a wireless device operating as a soft access point. In one embodiment, a wireless device includes a soft access point controller that configures the wireless device to operate as a group owner in a peer-to-peer wireless local area network. The soft access point controller includes a beacon controller. The beacon controller is configured to transmit beacon frames at a first periodic interval. The beacon controller is also configured to extend a discovery interval of a wireless station by transmitting acknowledgement packets at a second periodic interval. The second periodic interval is shorter than the first periodic interval and shorter than a minimum discovery scan timeout of the wireless station.

摘要： Apparatus, systems, and methods disclosed herein operate to provide wireless communication between personal mobile communication (PMC) devices. An emulated wireless access point (AP) at a first PMC device (PMC1) establishes a first tunneled direct link setup (TDLS) session between a first station module (STA1) incorporated into the PMC1 and a second station module (STA2) incorporated into a second PMC device (PMC2). Following establishment of the TDLS session, the wireless AP is allowed to sleep; and most infrastructure management duties are handled by the STA1 during the session. PMC device battery charge may be conserved as a result. The emulated wireless AP may also establish a second TDLS link to a third station module (STA3) incorporated into a third PMC device (PMC3). The STA1 may then bridge data traffic flow between the STA2 and the STA3. Such bridging operation may enable communication between two PMC devices otherwise unable to decode data received from the other.

摘要： Embodiments of the invention provide a method to allow a software access point (SAP)-enabled device to go to sleep as much as possible without sacrificing throughput and latency across networks. The SAP-enabled device defers transmissions from client stations if maximum end-to-end throughput that can be supported by the networks is below the maximum throughput supported by a connection to the client station.
