POLAR CODE TRANSMISSION METHOD AND APPARATUS

WIPO Patent Application WO/2018/149332

A1

Disclosed are a transmission method and a transmission apparatus, and a communication device. The transmission method comprises: performing polar encoding on a bit sequence to obtain an encoded sequence, wherein the bit sequence comprises control information and a cyclic redundancy check (CRC) sequence; slicing the encoded sequence to obtain n encoded sub-sequences, wherein n is an integer and n > 0; and respectively scrambling the n encoded sub-sequences and n scrambling sequences to obtain n scrambled sequences. By means of the transmission method, n scrambling sequences are redefined by using encoding and decoding features of a polar code, and log2n bits of information are additionally carried by means of the n scrambling sequences. By means of the encoding method, the signalling overhead is saved on.
