A wireless telecommunications system for stationary or semi-stationary equipment includes a main node and 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 transmits in at least one beam and receives in at least two beams, and the system indicates to the terminals that they may or may not transmit to the central node. Based upon certain criteria, two or more terminals located in different receive beams of the main node may be given permission to transmit to the central node simultaneously. Suitably, two or more terminals which are given permission to transmit simultaneously do so using the same frequency, or the same code, or the same time slot.
