  • Patent number: 10412654
    Abstract: The proposed layer solution defines two or more layers of relay nodes to convey traffic data from a source node to a destination node. All of the nodes in a given layer were selected for that layer because they each satisfied a signal quality requirement specified for that layer, where all relay nodes defined in one layer simultaneously start transmitting in response to a received transmission. Due to the layered approach, the destination node may be configured to decode only the traffic data relayed by the relay nodes in the immediately preceding (final) layer while treating any remaining received signals as noise. As a result, only those access nodes most likely to significantly contribute to and improve the signal quality of traffic data received at the destination node are selected as relay nodes for a particular source-destination node pair.

  • Patent number: 10368285
    Abstract: Embodiments of a station (STA), access point (AP) and method for communication in the presence of spatial reuse (SR) transmissions are generally described herein. An STA may determine a received signal strength indicator (RSSI) based on one or more inbound physical layer convergence procedure (PLCP) protocol data units (PPDUs) received from a destination STA. The STA may determine, based at least partly on a comparison between the RSSI and a predetermined threshold, whether SR transmissions by other STAs in the channel are permissible. The SR transmissions may be concurrent to transmissions by the STA within the TXOP in the channel. The STA may transmit a PPDU to the destination STA that includes an SR indicator that indicates whether the SR transmissions are permissible.

  • Patent number: 10326703
    Abstract: Some embodiments increase throughput across a connection between a host and a client by initializing the congestion window for that connection dynamically using a previously settled value from a prior instance of the connection established between the same or similar endpoints. An initialization agent tracks congestion window values for previously established connections between a host and various clients. For the tracked congestion window values of each monitored connection, the initialization agent stores an address identifying the client endpoint. When establishing a new connection, the initialization agent determines if the new connection is a recurring connection. A new connection is recurring when the new connection client address is similar or related to an address identified for a previous monitored connection.
