US Patent 11171741 Polar code transmission method and apparatus

Example polar code-based transmission methods and apparatus are provided, to apply polar encoding to a physical broadcast channel (PBCH). One example method includes performing polar encoding on a to-be-encoded first bit sequence by a transmit end to generate an encoded sequence. The transmit end performs a transformation operation on the encoded sequence to obtain a second bit sequence, where the transformation operation includes at least one of scrambling, interleaving, or reordering. The transmit end sends the second bit sequence in M inconsecutive time units, where at least two time intervals between the time units in the M inconsecutive time units are unequal.
