Abstract
Official abstract text for this publication.
Embodiments of the present disclosure provide a transmitter, a receiver and methods of operating a transmitter and a receiver. In one embodiment, the transmitter has at least three transmit antennas and includes a feedback decoding portion configured to recover at least one group-based channel quality indicator provided by a feedback signal from a receiver, wherein each group-based channel quality indicator corresponds to one of a set of transmission layer groupings. The transmitter also includes a modulator portion configured to generate at least one symbol stream and a mapping portion configured to multiplex each symbol stream to at least one transmission layer grouping. The transmitter further includes a pre-coder portion configured to couple the transmission layers to the transmit antennas for a transmission. The receiver includes a decoder portion which is configured to use decoded signals from at least one group to decode the other groups.
First claim
Opening claim text (preview).
What is claimed is: 1. A receiver, comprising: a receive portion employing a transmission from a transmitter having at least three transmit antennas and capable of a transmission layer mapping; a stream decoder portion configured to separate and demultiplex transmission layers corresponding to the transmission layer mapping; and a feedback generator portion configured to provide at least one group-based channel quality indicator that is fed back to the transmitter, wherein eac…
