    • Embodiments of a feedback generator (106) and decoder and methods of operating the feedback generator and decoder are presented. In one embodiment, the feedback generator includes a CQI compression module (107) configured to provide a compressed CQI for the user equipment corresponding to at least one sub-band, where a sub-band is composed of at least one resource block. The feedback generator also includes a transmit module (108) coupled to the CQI compression module and configured to transmit the compressed CQI to a serving base station (115). In one embodiment, the feedback decoder (120) includes a receive module (121) configured to receive a compressed CQI in the base station from user equipment corresponding to at least one sub-band. The feedback decoder also includes a CQI restoration module (122) coupled to the receive module and configured to provide a restored CQI from the compressed CQI for the at least one sub-band.

    • Embodiments of the present disclosure provide a transmitter (100), a receiver and methods of operating a transmitter and a receiver. In one embodiment, the transmitter is for use with multiple transmit antennas and includes an encoding unit (105) configured to segment input bits into one or more code blocks. The transmitter also includes a rate matching unit (120) configured to generate a stream of transmit bits from the one or more code blocks, wherein a group of transmit bits allocated to one resource element originates from only one of the one or more code blocks. The transmitter further includes a mapping unit (125) configured to provide modulated symbols from the stream of transmit bits on a number of spatial transmission layers for one or more resource elements. The transmitter still further includes a transmit unit (140) configured to transmit the modulated symbols employing the multiple transmit antennas.
