Abstract: Embodiments of the present disclosure relate to a method and device for interleaving data in a wireless communication system. For example, a method of interleaving data in a wireless communication system comprises: determining, based on the number of a plurality of bits to be interleaved, a size of an interleaving array for interleaving the plurality of bits, wherein the number of rows is H and the number of columns is 2H-1 in the interleaving array; dividing the plurality of bits into a plurality of subsets based on the size of the interleaving array, such that an i-th subset of the plurality of subsets at most comprises 2(H-1-i)+1 consecutive bits, wherein i is a nonnegative integer smaller than H; writing the plurality of subsets respectively into the interleaving array, comprising for the i-th subset: writing an initial bit in the i-th subset into a position y(i, H-1) in an i-th row and an (H-1)-th column of the interleaving array; and writing subsequent bits of the initial bit respectively into subsequent rows of the i-th row, wherein at least two positions for writing the subsequent bits in an r-th row comprise y(r, H-1−(r-i)) and y(r, H-1+(r-i)); and reading the written plurality of bits successively column by column from the interleaving array.

Abstract: A method for encoding a sequence of control information bits comprising: generating a sequence of error detection bits based on the sequence of control information bits; generating a sequence of error correction bits based on the sequence of control information bits; and distributing the sequence of error detection bits and the sequence of error correction bits between the sequence of control information bits to form a combined sequence of bits, such that the bit order of the combined sequence of bits following the distribution enables an error detection check to be performed before or after a first error correction check bit.

Abstract: Embodiments of the present disclosure relate to a method, device and computer readable medium for interleaving data in a wireless communication system. The method described herein comprises determining, based on a first number of bits in a bit sequence to be interleaved, a second number of rows in a triangular interleaver for interleaving the bits. The method also comprises dividing the bit subsequence into the second number of subsequences associated with the rows, a difference between numbers of bits in any two successive subsequences of the subsequences being a predetermined value. The method further comprises writing the second number of subsequences into the triangular interleaver in an order of the rows, the writing comprising, for a given row in the triangular interleaver, determining, based on an index of the given row, a writing order of bits having odd indexes and bits having even indexes in a subsequence associated with the given row.
