Abstract:
1. A method for transmitting data from a transmitter unit in a multiple-input multiple-output (MIMO) communication system, comprising: receiving channel state information (CSI) from a receiver unit; processing data for transmission to the receiver unit based on the received CSI, wherein the received CSI comprises signal-to-noise-plus-interference (SNR) estimates for each of a plurality of transmission channels, the processing at the transmitter unit including coding data for each transmission channel based on the SNR estimate for the transmission channel, and the data for each transmission channel is independently coded based on the SNR estimate for the transmission channel where the coding includes coding the data for the transmission channel with a fixed base code; and adjusting puncturing of coded bits based on the SNR estimate for the transmission channel.
