摘要： 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.

摘要： A multiple-input multiple-output (MIMO) wireless communication system. A transmitter that includes a plurality of transmit antennas selects one of a spatial multiplexing scheme and a spatial diversity scheme, processes a signal in the selected transmission scheme, and transmits the signal through the plurality of transmit antennas. A receiver that includes a plurality of receive antennas processes a signal in a reception scheme mapped to a transmission scheme of the transmitter. The transmission schemes include a transmission scheme for maximizing diversity gain and a transmission scheme for maximizing spectral efficiency. The MIMO communication system using an adaptive transmission mode switching technique performs switching between MIMO transmission modes using spatial selectivity of a channel, thereby obtaining maximum gain in a signal to noise ratio (SNR) and spectral efficiency according to channel state.

摘要： The invention relates to an information encoding method for the backward channel of a base station (BS) of a mobile radio system. The base station (BS) comprises M resources and periodically emits (t), toward user terminals (UT), pilot signals enabling, via the latter, the measurement of quality of transmission of resources values (I). The storage (A) of at least one quality of reception of resources value ensues and the transformation (B) of each quality of reception of resources value (II) ensues by quantization into a quantized index value representative of the quality of reception value and constitutive of a metrix relative to each resource. The invention is for use in SDMA and/or OFDMA.
