  • Publication number: 20190182685
    Abstract: Wireless directional communication is performed in the millimeter wave (mmW) band by nodes in a wireless mesh network. Beacon frames are configured to incorporate an activity indicator that signals active and inactive communication directions on the mmW, with a flag for each respective direction of communication (transmit or receive). The activity indicator is utilized to enhance route and beam selection so as to obtain connections subject to less interference, and/or that create less interference to other stations. The activity indicator is also, or alternately, utilized for improving selections of a connection to an access point (AP) or station (STA) or mesh station (MSTA), toward reducing interference, or selecting which beam from a given AP, STA, or MSTA is to be utilized. Distributed interference and resource coordination can be initiated, and/or rerouting determined, based on the activity indicator.

  • Publication number: 20190141645
    Abstract: Wireless communication is performed by stations (nodes) in a wireless mesh network by forming nodes into a mesh network without the need of network-wide synchronization and without needing to form active links between potential neighbors. Nodes obtain information on neighbors in the network by listening to transmitted beacons from these nearby nodes. Synchronization and active links are established when a data transmission session is triggered and initiated by the route setup process. The link formation process performed when establishing a new route performs both beamforming and synchronization. In situations in which a new route does not intersect other active routes then independent synchronization is performed; but when intersecting routes exist, the new route is synchronized with all intersecting routes where nodes are configured to serve both routes.

  • Publication number: 20190104483
    Abstract: There is provided a wireless communication apparatus and wireless communication method, which can perform information transfer, while suppressing interference to other terminal stations, and preventing a reduction of a transmission opportunity of other terminal stations. By causing the transmission power to be reduced, at the time when a traffic amount to be transmitted and received by itself increases, a terminal station which performs wireless access based on CSMA on a mesh network can suppress interference to other surrounding terminal stations, and can prevent a reduction of a transmission opportunity of other terminal stations. By measuring the number of and sizes of packets to be transmitted and received, it is possible for a terminal station to comprehend the traffic amount to be transmitted and received by itself, and perform a control of the transmission power by this.

  • Publication number: 20190104465
    Abstract: An apparatus and method for adaptive network discovery signaling. Information is collected in a database of events, such as the discovery of a new station. The event information (e.g., new station, antenna sectors, active links) is shared with a central coordinator, or other stations in the network. Based on events, at this or other stations, signal transmission forms are adapted, for example for transmitting the beacon signals and notification signals. Adaptations of signal transmission include changing how frequently signaling is performed, timing of signaling, adjusting beam width, and/or adjusting directionality.

  • Publication number: 20190097913
    Abstract: A method and apparatus for routing multiple data streams simultaneously through independent routes between multiple-input-multiple-output (MIMO) stations in a mesh network. The disclosed feature allows transmission of multiple data streams via multiple routes from a source station (STA) to a destination station (STA), which are both MIMO capable, even though the relay STAs in between can be a single-input-single-output (SISO) STA. An extended routing request (RREQ) and routing reply (RREP) frames are utilized which provide a primary and secondary flag indication, which is utilized in combination with advanced programming for setting path cost metrics to assure independence of primary and secondary routes.

  • Publication number: 20190082379
    Abstract: Multi-band signaling is described for reducing signaling overhead in an apparatus and method for communications within a mesh network. The communications involve using two different beacon signals on two different communication channels. Peer beacons are sent using directional millimeter-wave (mmW) communications to provide time synchronization and resource management information to maintain existing links among one or more neighboring peer stations. A separate network discovery beacon is sent over a sub-6 GHz communication channel, to provide mesh network profile information that identifies the mesh network to aid network discovery for wireless communication stations wanting to join the mesh network.
