Abstract: Embodiments provide a Polar code transmission method and apparatus. A bit sequence is encoded into a code sequence using Polar code by a network device. The bit sequence contains a control signaling and a Cyclic Redundancy Code (CRC) sequence. The code sequence is transformed into M copies such that an ith information copy of the M copies multiples by a first matrix of the power of (i−1). M is an integer and M>0. M copies of codeword 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.

Abstract: A method to explicitly indicate the version information while still supporting soft combining is disclosed. A polar code encoder maps q bits to q positions of q sub-channels, q is a positive integer; wherein the q bits are used to indicate a version of encoded codeword; map 1 to a special frozen bit corresponding to the q bits; map K−q information bits to K−q positions for the K−q information bits, K is an integer, K>q; and perform polar encoding over an input vector u0N−1, comprising the q bits, the special frozen bit and the K−q information bits, with the length of N, N is an integer, N>=K. With this method, there is no need to make blind detection to achieve the version information of transmitted payload, which reduces power consumption for a receiver.

Abstract: A communication method includes determining a reserved carrier in a bandwidth part (BWP) based on a tone reservation (TR) pattern and a first correspondence. The TR pattern includes a set of subcarriers used as reserved carriers. The first correspondence is a correspondence between an index that is of a subcarrier in the TR pattern and that is in the TR pattern and an index that is of the subcarrier in the TR pattern and that is based on a first common resource block (CRB). The communication method further includes outputting a time domain signal based on the reserved carrier in the BWP.
