Abstract
A wireless communication apparatus, system or method utilizing directional data transmission over a communication (e.g., mmW) band, and broadcasting time and directional allocations in each direction. Stations transmit beacons containing time, directional allocations and unallocated slots in their direction of transmission. Stations comparing beam identifications with received allocation to determine if the allocation is in the direction of reception. Stations performing receiver beamforming with a station from which a beacon was received in order to determine if the station can access the direction (channel) in its intended direction.
