Abstract:
The invention relates to a communication by return pathway from a terminal to a transmitter for reducing in particular interference between beams from the transmitter. A telecommunication system comprises a transmitter designed to render simultaneously active a first number of beams, as resources for a plurality of user terminals. Within the sense of the invention, each terminal calculates, while taking account of interference noise, at least one second preferred number of beams to be rendered simultaneously active by the transmitter, and sends to the transmitter, through the return pathway, an indication of this second preferred number, among information about the quality of reception. The transmitter can then adjust the first number of beams to be rendered active, as a function of the returns from the terminals, for a next burst.
