A pre-coder selection based on resource block grouping

摘要

C:VR~fbtMWOCCLAS39t334Oj .DOC-IlMOM/I I The present invention provides a receiver. In one embodiment, the receiver includes a receive portion 5 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 10 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 15 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 20 frequency-domain resource blocks. 1 Of9 Iii 1 i I -I--J -- I W_ ID co 0 0' . ... ...... 0)
