摘要： A communications device receive data from a wireless communications network by detecting from one or more control channels of a wireless access interface one or more encoded data units of a plurality of encoded data units into which an error correction encoded control information has been divided in accordance with an incremental redundancy scheme. The communications device decodes the error correction encoded control information by combining the one or more detected encoded data units in accordance with an arrangement of encoded bits of the error correction encoded control information in each of the plurality of encoded data units. Each of the plurality of encoded data units comprises a different set of the encoded bits according to a different redundancy version number of the incremental redundancy scheme.
