Title: POLAR CODE TRANSMISSION METHOD AND APPARATUS
Abstract:
Embodiments of the application provide a Polar code transmission method, the method comprising: encoding, by a network device, a bit sequence into a code sequence using Polar code, wherein the bit sequence contains a control signaling and a Cyclic Redundancy Code (CRC) sequence; and transforming, by the network device, the code sequence into M copies, wherein an ist information copy of the M copies multiples by a first matrix of the power of (i-1), M is an integer and M>0, 1≤i≤M. A Polar code transmission apparatus is also provided. By using the above method and apparatus, M copies of codeword x was encoded by Polar code, the M copies implicitly conveys different time stamp information, which is suitable for the transmission of PBCH in 5G communication system, signaling overhead is also reduced.
