Patent ID: 8320357

Claim:
A wireless telecommunications system for stationary or semi-stationary equipment having a main node operable with a first plurality of terminals belonging to the same access subset and arranged to receive from and transmit to the main node, the main node adapted to transmit in at least one transmit beam and receive in at least two receive beams, the system comprising: a transmitter in the main node that transmits indications to first and second terminals indicating whether each terminal may or may not transmit to the main node; wherein when a first terminal located at a first azimuth angle in a first receive beam is transmitting, the main node is adapted to determine whether a second terminal located at a second azimuth angle in a second receive beam is permitted to transmit simultaneously with the first terminal, wherein the main node permits the second terminal to transmit simultaneously when the difference between the gain of the second beam at the second azimuth angle and the gain of the second beam at the first azimuth angle is greater than a threshold level; and wherein upon determining that the second terminal can be permitted to transmit to the main node simultaneously with the first terminal, the transmitter in the main node transmits an indication to the second terminal granting permission for the second terminal to transmit simultaneously with the first terminal.
