Abstract:
1. A method of wireless telecommunication wherein an access point transmits a signal to at least one terminal via a transmission channel; the telecommunications method being used in a system comprising at least: first and second access points; first and second terminals that may be serviced by said first and second access points; and the first terminal being adapted to estimate first transmission channels between said first terminal and said first and second access points and the second terminal being adapted to estimate second transmission channels between said second terminal and said first and second access points; and wherein: the first and second access points schedule the servicing of the terminals according to a predetermined criterion common to the first and second access points; a cooperation cluster comprising at least said access points jointly servicing said terminals is defined; said system further comprises one or more access points not belonging to said cooperation cluster; the method comprising: a. estimating, by the first terminal, said first transmission channels, and, by the second terminal, said second transmission channels; b. communicating to the first and second access points a first indication concerning said first transmission channels by said first terminal and a second indication concerning said second transmission channels by said second terminal; c. independently scheduling said servicing of the terminals by the first and second access points using transmission parameters based on said first and second indications; and d. jointly servicing said terminals by the first and second access points; wherein: the first indication and the second indication respectively comprise information relating to a signal-to-interference plus noise ratio associated with the first and second terminals; and the power of the signal in a signal-to-interference plus noise ratio associated with the terminal is defined as a sum of powers received by said terminal from the access points belonging to the cooperation cluster and power of interference in a signal-to-interference plus noise ratio associated with a terminal is defined as a sum of the powers received by said terminal from the access points not belonging to said cooperation cluster.
