Abstract

For joint MIMO-OFDMA link adaptation and scheduling, channel quality feedback needs to be quantized, sparse and irregular. For flexible scheduling, prediction of the quantized channel at the base-station is needed. We propose measurement of 3D channel correlation parameters by the terminals and signalling back to the base station, which enables prediction of the quantized channel by multi-dimensional Wiener filtering. The scheme is shown to improve adaptive choice of transmission parameters and to avoid mis-adaptation due to control lag. Different schemes of correlation feedback signalling are discussed in terms of (time-variant) expected throughput.
