Claim Text:
1. A method of operating a terminal in a radio access network: receiving a transmission of first and second data blocks over respective first and second multiple-input-multiple-output, MIMO, layers during a first transmission time interval, TTI; generating respective first and second demodulated codewords corresponding to the transmission of the first and second data blocks; decoding the first and second demodulated codewords; responsive to failure decoding the first demodulated codeword and success decoding the second demodulated codeword, transmitting a negative acknowledgement indicating failure receiving the first and second data blocks; after transmitting the negative acknowledgment, receiving a retransmission of the first and second data blocks over the respective first and second MIMO layers during a second transmission time interval; reducing interference of the retransmission responsive to the second demodulated codeword; responsive to reducing the interference of the retransmission, generating a third demodulated codeword corresponding to the retransmission of the first data block; and decoding the third demodulated codeword.
