Abstract

A transmitter for transmitting data to a receiver of a wireless communication network, the transmitter includes at least one antenna, a codebook, an encoder, and a transceiver coupled to the encoder and to the at least one antenna. The codebook includes a plurality of codewords, each codeword being a vector including a plurality of symbols, each symbol to be transmitted over resources of the wireless communication network. The encoder is configured to receive an information message to be transmitted to a receiver of the wireless communication network, to select from the codebook the codeword associated with the received information message, and to divide the selected codeword into a plurality of sub-codewords. The transceiver is configured to transmit via the at least one antenna a first sub-codeword, and to transmit via the at least one antenna a second sub-codeword responsive to an indication that the encoded information message was not successfully decoded at the receiver on the basis of the received first sub-codeword.
