Abstract
Official abstract text for this publication.
The present invention provides a receiver. In one embodiment, the receiver includes a receive portion employing transmission signals from a transmitter having multiple antennas and capable of providing channel estimates. The receiver also includes a feedback generator portion configured to provide to the transmitter a pre-coder selection for data transmission that is based on the channel estimates, wherein the pre-coder selection corresponds to a grouping of frequency-domain resource blocks. The present invention also provides a transmitter having multiple antennas. In one embodiment, the transmitter includes a transmit portion coupled to the multiple antennas and capable of applying pre-coding to a data transmission for a receiver. The transmitter also includes a feedback decoding portion configured to decode a pre-coder selection for the data transmission that is fed back from the receiver, wherein the pre-coder selection corresponds to a grouping of frequency-domain resource blocks.
First claim
Opening claim text (preview).
What is claimed is: 1. A transmitter having a plurality of antennas, comprising: a feedback decoding portion configured to extract a pre-coder selection of N pre-coders provided by a feedback signal from a receiver in which the pre-coder selection provides a single pre-coder for a group of contiguous resource blocks, wherein the N pre-coders correspond to N groups of resource blocks, N being an integer number of at least 1; and a transmit portion coupled to the plurality of ante…
