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.

A deinterleaving method and a deinterleaving system performing the same are disclosed. According to an example embodiment, a data processing method includes dividing data into first data blocks of a first number of bits, performing deinterleaving on the first data blocks, and dividing deinterleaved data into second data blocks of a second number of bits and outputting the second data blocks, wherein the first number of bits is determined based on a minimum switching unit of a deinterleaving operation and the second number of bits.
