    Abstract: A first group of bits (100, 102, 106), e.g., header symbols/bits, are interleaved to form a first group of interleaved bits. A second group of bits (104), e.g., data symbols/bits, are interleaved to form a second group of interleaved bits. The first and second groups of interleaved bits are mapped to an information burst (114). The first and second groups of interleaved bits may be mapped to the information burst relative to a group of known symbols (116) forming a training sequence. A disadvantaged bit location, i.e., a bit location within the mapping having a relative high probability of incurring a bit error, is identified and an advantaged bit location, i.e., a bit location within the mapping having a relatively low probability of incurring a bit error, is identified. A first group bit from the first group of interleaved bits mapped to the disadvantaged bit location is remapped to the advantaged bit location while a second group bit from the second group of interleaved bits mapped to the advantaged bit location is remapped to the disadvantaged bit location.

    Abstract translation: 第一比特组(100,102,106),例如头部符号/比特被交织以形成第一组交织比特。 第二组比特(104),例如数据符号/比特,被交织以形成第二组交织比特。 第一和第二组交织比特被映射到信息突发(114)。 第一和第二组交错比特可以相对于形成训练序列的一组已知符号(116)被映射到信息突发。 识别弱势比特位置,即具有相对较高的发生比特错误概率的映射内的比特位置,并且有利的比特位置,即映射内的比特位置具有相对较低的发生比特误差的概率 ,被识别。 映射到处于不利位置的位置的第一组交错比特的第一组比特重新映射到优势比特位置,而来自映射到优势比特位置的第二组交织比特的第二组比特重新映射到处于不利位的比特位置。

    Abstract: A method in a wireless communication device (103, 110) comprises attempting to decode combined control channel elements received at the wireless communication device, determining whether the attempted decoding of the combined control channel elements is successful, and attempting to decode a single control channel element if the attempt to decode the combined control channel elements is not successful
