Abstract (en)

[origin: WO2009083680A1] 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 (Fl, F2, F3), in the guise of the 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. On its side, the transmitter (BS) 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.
