Patent ID: 7110759

Claim:
A local radiocommunication system, comprising: at least one central controller; several bases connected to the controller and controlled by said controller; and several terminals, each communicating with at least one of the bases according to a master/slave process where each base plays a role of master and each terminal plays a role of slave at least after setting up a radio link between said base and said terminal, the base communicating with the terminals according to the same time division multiple access local radiocommunication protocol, said protocol providing, for each base, successive time slots during which either an uplink information packet sent by a terminal to said base or a downlink information packet sent by said base to said terminal are transmitted, and said base being adapted to determine in advance and impose planned transmissions between said base and said terminal, said planned transmissions comprising planned transmissions of downlink information and planned slots of uplink information, where the terminal is authorized to transmit an uplink information packet to the base, and at least some of said bases are susceptible to reciprocal interference, preventing the reception by one of said bases of an uplink information packet when another of said bases is transmitting a downlink information packet, the different bases being adapted to transmit to the controller, in real time, at least chronological information relating to transmissions planned by said bases, the controller being adapted to determine whether there is a risk of interferences occurring between said planned transmissions, and to impose on the base a chronology of said planned transmissions which enables at least some of said interferences to be avoided.
