Abstract
A method in a transmitter comprises transmitting a first data block to a first user, using an index modulation scheme and using SSD for transmitting the first data block. In some embodiments, the index modulation scheme is index-modulated OFDM and the indices comprise subcarrier indices. The method further comprises determining that a retransmission of the first data block to the first user is needed, and rearranging a bit mapping of bits in the first data block to indices used in the index modulation scheme, compared to a bit mapping previously used for transmitting the first data block to the first user using the index modulation scheme. The method further comprises retransmitting the second data block to the first user, where this retransmitting comprises using the index modulation scheme with the rearranged bit mapping and using SSD.
