COMMUNICATION BY RETURN PATHWAY FROM A TERMINAL TO A TRANSMITTER FOR REDUCING IN PARTICULAR INTERFERENCE BETWEEN BEAMS FROM THE TRANSMITTER
First Claim
1. A method of telecommunication in a system including at least one transmitter arranged in order to activate simultaneously a first number of beams, as resources for a plurality of user terminals, in which the user terminals receive telecommunications data via said beams,wherein at least one of the terminals transmits to the transmitter, by return pathway, an indication of at least one second preferred number of beams to be activated simultaneously by the transmitter.

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.

13. A signal transmitted by return pathway by at least one terminal to a transmitter in a telecommunications system, wherein the transmitter is arranged in order to activate simultaneously a first number of beams, as resources for a plurality of user terminals, the transmitter transmitting telecommunications data to the user terminals, by said beams, the signal comprising an indication of a second preferred number of beams to be activated simultaneously by the transmitter.
