Abstract:
Examples pertaining to additional bit freezing for polar coding are described. An apparatus performs polar coding to encode a plurality of input subblocks of information bits, frozen bits and optional cyclic redundancy check (CRC) bits to generate a plurality of subblocks of coded bits. The apparatus then transmits at least some of the subblocks of coded bits. In performing the polar coding, the apparatus additionally freezes one of the plurality of input subblocks corresponding to one of the interleaved plurality of subblocks of coded bits which decreases polarization gain due to puncturing.
