摘要： Methods and apparatuses for providing CQI feedback with common code rate to a transmitter station are described herein. In one implementation, the methods may include a receiver station that is communicatively linked to a transmitter station via k spatial channels transmitting a first CQI to the transmitter station that indicates a modulation level for use by the transmitter station to transmit (i.e., to configure for transmission) a first of k streams of signals to be transmitted to the receiver station. The first CQI may further include a common code rate to be used by the transmitter station for transmitting the first of the k streams of signals as well as for transmitting the rest of the k−1 additional streams of signals to the receiver station. The receiver station may further transmit to the transmitter station k−1 additional CQIs to indicate to the transmitter station the k−1 modulation levels to be used by the transmitter station for transmitting the k−1 additional streams of signals to the receiver station.

摘要： Dedicated pilot signals are transmitted from a transmitting device to a receiving device through a multicarrier MIMO channel in addition to data signals and common pilot signals. The dedicated pilot signals may be used by the receiving device to validate whether a predetermined beamforming matrix (i.e., a beamforming matrix identified by the receiving device) was used by the transmitting device to precode the transmitted data. If a different beamforming matrix was used for the preceding, the receiving device may use this matrix to demodulate the received data.
