    摘要: A method and an apparatus for performing hybrid automatic repeat request (HARQ) using constellation rearrangement and a circular buffer in a wireless communication system is provided. An encoded information bit is stored into a circular buffer. A transport block in selected from the circular buffer. A bit set comprising n bits of the transport block is mapped to a data symbol on a constellation for 2n-QAM modulation according to a first mapping order. The bit set is mapped according to a second mapping order when the bits of the transport block are subject to wrap-around at the end of the circular buffer.

    摘要: A method and apparatus of transmitting control information in a wireless communication system is provided. A sequence corresponding to control information from a sequence set is determined. A reference modulation symbol set corresponding to a mini unit by modulating the sequence is generated. At least one reordered modulation symbol set is generated by reordering and repeating the reference modulation symbol set. The at least one reordered modulation symbol set is reordered in a unit of a subgroup. The reference modulation symbol set and the at least one reordered modulation symbol set are mapped to the plurality of mini units in the resource unit respectively.
