Patent ID: 7783258

Claim:
A method of synchronizing transmission between two nodes in a wireless distribution network, at least a first node having a multiple beam antenna, said method comprising the steps of: dividing transmission bandwidth into transmission slots; obtaining a multi-dimensional interference table giving an expected individual interference profile for each respective node, said table showing particular time slots on particular frequencies that should not be used for transmission, and with respect to the at least first node showing particular time slots or particular frequencies that should not be used for transmission for at least two different beams of the multiple beam antenna of the at least first node; and agreeing to a synchronized transmission schedule between the nodes by an initiating node signaling to a proposed recipient a proposal of a slot for a scheduled transmission, where the expected interference profile of each node meets predetermined criteria and wherein both of the two nodes referring to their respective interference profiles participate in the selection of a suitable transmission slot for direct communication between said two nodes.
