Abstract

A multi-tiered CSI vector quantizer (VQ) is provided for time-correlated channels. The VQ operates by quantizing channel state information by reference to both the current channel state information and a prior channel state quantization. A system is also provided that uses multi-tiered CSI quantizers. Enhanced signaling between the transmitter and receivers is provided in order to facilitate the use of multi-tiered CSI quantizers.
