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.
