Abstract:
A procedure to establish a link in a directional wireless system where two nodes cannot listen to each other unless optimized beamforming pair is used and timing and framing synchronization is acquired. The procedure determines a set of beamforming pairs that the nodes can use for communication in addition to acquiring the framing and timing synchronization. Training packets are periodically transmitted by a transmitter while a receiver listens in each of a number of receive directions. Training packets are sent N times in N directions while a receiver listens in each of M receive directions until all N×M possible transmit and receive direction pair possibilities are tried. The receiver informs the transmitter which transmit and receive direction pairs were successful in creating communication links between the nodes.

Claim (Index 1):
A method of identifying one or more transmit and receive beamforming direction pairs between an initiator node and a responder node in a wireless communication network, comprising:\n transmitting training packets from the initiator node for a number of times in a number of beamforming directions; at the responder node, trying to asynchronously detect a training packet in a number of receive directions; detecting a training packet at the responder node and using synchronization information in the detected training packet to synchronize the responder node to the initiator node; and once the responder node and the initiator node are synchronized,\n transmitting training packets from the initiator node in each of a number of possible transmit beamforming directions; \n attempting to detect a training packet at the responder node in each of a number of possible receive beamforming directions; and \n providing feedback to the initiator node that indicates one or more transmit and receive beamforming direction pairs with which the responder node can detect a training packet.
