Hybrid Automatic Repeat Request (HARQ) and retransmission procedures for multi-stream transmission are disclosed. An example method begins with the simultaneous sending (410) of first and second data packets, in respective first and second MIMO streams of a rank-2 transmission, and with the transmission (420) of corresponding control data for each of the first and second streams, using first and second associated control channels, respectively. The first and second associated control channels are distinguishable by their respective mappings to the transmitted signal. The method continues with the receiving (430) of HARQ data indicating that the first data packet was successfully decoded, while the second data packet was not. In response, the wireless transceiver retransmits (440) the second data packet in a single stream of a rank-1 MIMO transmission, and transmits (450) corresponding control data for the single stream using the second associated control channel. |
