An example method may include decoding, at a UE, a downlink data transmission and determining, over each of multiple streams including a single stream and two dual streams, whether to transmit an acknowledge (ACK) or a negative acknowledge (NACK) message to a base station based on a result of the decoding. Further, the example method may include calculating a signal noise ratio (SNR) value for adjusting each of the multiple streams based on the determining. Further still, the example method may include mapping the calculated SNR value of the single stream to a first channel quality indicator (CQI) value. Moreover, the example method may include mapping the calculated SNR value of the two dual streams to a second CQI value. In addition, the example method may include transmitting the first CQI value and the second CQI value to the base station. |
