Wireless communication

1. 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.

2. A method of synchronizing transmission as claimed in claim 1 , wherein the expected interference profile is obtained by detecting interference received at each node.

3. A method of synchronizing transmission as claimed in claim 1 , where the interference profile is characterized according to further transmission parameters.

4. A method of synchronizing transmission as claimed in claim 3 , wherein the transmission parameters include time and/or frequency and/or polarisation.

5. A method of synchronizing transmission as claimed in claim 4 , wherein each node comprises a multiple beam antenna.

6. A node in a wireless distribution network comprising:

a multiple beam antenna;

a memory for storing a multi-dimensional interference table giving an expected individual interference profile of the node, said table showing particular time slots on particular frequencies of at least two different beams of a multiple beam antenna of the node that should not be used for transmission;

a processor for determining where the expected interference profile of the node meets predetermined criteria; and

a transceiver for communicating directly with a second node by use of transmission slots to agree to a synchronized transmission schedule between said two nodes according to the determination of the processor and in case of the node initiating a communication, the node being arranged for signaling to a proposed recipient a proposal of a slot for a scheduled transmission, and wherein the determination comprises the selection of a suitable transmission slot based on the respective interference profiles of both nodes.

7. A wireless network comprising a plurality of nodes as claimed in claim 6 .

8. A method of communication 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;

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; and

effecting communication in accordance with the synchronized transmission schedule.
