Abstract: Embodiments of the application provide a method for transmitting data in a wireless communication network. A device of the network receives a bit sequence of K information bits. The device polar codes the bit sequence to obtain a first encoded sequence, wherein a length of the first encoded sequence is N, and N is greater than or equal to K. The device block interleaves the first encoded sequence to obtain an interleaved bit sequence. The device determines a transmission code rate R. When the transmission code rate R is less than the code rate threshold, the device outputs a second bit sequence. The length of the second bit sequence is M, M is smaller than N. The second bit sequence is punctured from the interleaved bit sequence by removing (N−M) bits from beginning of the interleaved bit sequence.

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.
