Abstract: A method for polar encoding includes: receiving a message including information bits; encoding the message using a first polar code to obtain a first codeword; and encoding the message using a second polar code to obtain a second codeword. The second codeword includes two parts, and the first part of the second codeword is same as the first codeword. The method for polar encoding also includes transmitting the first codeword to a receiver in a first transmission; and transmitting the second part of the second codeword in a second transmission without transmitting the first part of the second codeword when the receiver is unable to decode the message based on the first codeword.

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: Embodiment techniques map parity bits to sub-channels based on their row weights. In one example, an embodiment technique includes allocating, from a set of sub-channels, one or more sub-channels for one or more parity bits based on row weights for sub-channels in a subset of sub-channels within the set of sub-channels, mapping information bits to remaining sub-channels in the set of sub-channels based on a reliability of the remaining sub-channels without mapping any of the information bits to the one or more sub-channels allocated for the one or more parity bits, polar encoding the information bits and the one or more parity bits based on at least the mapping of the information bits to the remaining sub-channels to obtain encoded bits, and transmitting the encoded bits to another device.
