摘要： 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.

摘要： Embodiments of this application provide a method for processing information bits in a wireless communication network. A device obtains a Polar encoded bit sequence, then divide the Polar encoded bit sequence into g groups that are of equal length N/g, wherein g is 32. The device block interleaves the g groups to obtain an interleaved bit sequence according to a sequence S, wherein the sequence S comprises: group numbers of the g groups, wherein a group whose number is 0 is the first element in the sequence S, wherein a group whose number is 12 is the 17th element in the sequence S, wherein a group whose number is 31 is the 32nd element in the sequence S, wherein the S is an integer and output the interleaved bit sequence.
