Published: — with international search report (Art. 21(3)) (54) Title: MAPPING OF CHANNEL ENCODED BITS TO SYMBOL FOR RETRANSMISSION (57) : Aspects of the present disclosure relate to retransmissions of data within wireless communication networks. For a retransmission, at least a portion of the encoded bits of an original transmission may be mapped to different bit locations in one or more modulated symbols based on a non-random mapping rule. In some examples, the encoded bits of a symbol may be reversed within the symbol for a retransmission. In other examples, the first and last encoded bits within a symbol may be switched for a retransmission. Other non-random mapping rules, such as a bit location offset, may also be used to map encoded bits to different bit locations in the modulated symbol within a retransmission. Transmit first code block to receiving device 906 908 H Generate second code block including second 910 encoded bits Map at least portion of corresponding encoded bits to different bit locations with in second 912 symbols than first symbols Transm second code block to it receiving H device 914 ) FIG. 9
