    • A mobile device estimates channel state information (CSI) comprising, for example, CQI and/or SNR, for a downlink channel. The estimated CSI is non-uniformly quantized and transmitted to the base station over a finite-rate feedback channel. Different portions of the estimated CSI are quantized using different quantization step sizes, which are determined according to a performance metric function such as a channel capacity function of the estimated CSI. A quantization step size for a portion of the estimated CSI is increased if a low distribution probability is indicated by the portion of the estimated CSI. A quantization step size for a portion of the estimated CSI is decreased if a high distribution probability is indicated. The mobile device quantizes the estimated CSI using the determined quantization step sizes to transmit to the base station over the finite-rate feedback channel. Downlink data transmission is received according to the transmitted CSI.

    • A mobile device comprises multiple receive antennas to receive spatially independent multipath signals from multiple transmit antennas located on a single base station. The mobile device concurrently generates a RAKE-based equivalent single path signal (RAKE ESPS) and an equalizer-based equivalent single path signal (equalizer ESPS) for the multipath signals received via each receive antenna. The generated RAKE ESPS or the generated equalizer ESPS is selected for channel decoding. Reference signal components are extracted from the multipath signals received to determine noise components, which is used to determine signal quality information of the generated RAKE ESPS and the generated equalizer ESPS. A final ESPS is selected from the generated RAKE ESPS and the generated equalizer ESPS based on the corresponding determined signal quality information. The selected final ESPS is diversity processed by combining signal components over the transmit/receive antennas. Transmission parameters are determined for channel decoding the combined signals.
