A wireless terminal may receive downlink signaling over a downlink signaling channel from a base station, with the downlink signaling including a DTX indicator for a first downlink MIMO layer and a retransmission data indicator for a second downlink MIMO layer. Soft bits for the second MIMO layer may be generated for a TTI corresponding to the downlink signaling, and the soft bits may be decoded. After decoding the soft bits, an ACK message for the second MIMO layer may be transmitted responsive to success decoding the soft bits or a NACK message for the second MIMO layer may be transmitted responsive to failure decoding the soft bits, and a default response may be transmitted for the first MIMO layer for the TTI. |
