A plurality of angle values associated with the one or more spatial or space-time streams and the one or more OFDM tones of the plurality of OFDM tones are determined. For each of the one or more spatial or space time streams, a per-tone signal to noise ratio (PT-SNR) associated with one or more OFDM tone of the plurality of OFDM tones is determined, and an average signal to noise ratio (avg-SNR) is determined by averaging signal to noise ratio (SNR) values corresponding to one or more OFDM tones of the plurality of OFDM tones. A feedback report is generated to include at least i) the plurality of angle values, ii) the PT-SNRs, and iii) the avg-SNR.

Abstract: A transmitter-side estimation of the complex channel influence between function variable value transmitters and function receivers is limited to the estimation of the magnitude of the channel influence, so that a pre-distortion of the symbols of the symbol sequences depends on an inverse of the magnitude of the channel influence, but is independent of a phase of the channel influence. Easing the channel estimation does not change the central tendency of the calculated function results transmitted over the multiple channel. Alternatively, on the side of the function receiver, a statistical quantity describing the multiple-access channel is determined. For this purpose, it is sufficient when the function variable value transmitters transmit constant power signals over the multiple-access channel in a channel estimation phase. Thus, the channel estimation effort is transferred to the function receiver and hence occurs less frequently, which again reduces the overall energy expenditure.

In each RF transmit chain of a MIMO system that utilizes polar modulation, aspects of the invention may enable generating a signal representative of an amplitude of a pair of phase-quadrature baseband signals; and controlling a voltage and/or current regulator utilizing said generated signal. In this regard, a voltage and/or current supplied to a power amplifier and/or mixer of one or more of the transmit chains may be controlled based on the generated signal. Additionally, a gain of a power amplifier for each RF transmit chain may be controlled utilizing said signal representative of an amplitude.
