Abstract: A method of transmitting a wireless signal (FIGS. 3A-3C) is disclosed. A data stream is divided (306) into a first data stream and a second data stream. The first data stream is encoded (300) at a first data rate. The second data stream is encoded (320) at a second data rate different from the first data rate. A first part of the encoded first data stream is transmitted from a first transmit antenna (308). A second part of the encoded first data stream is transmitted from a second transmit antenna (312).

Abstract: 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.
