Method and apparatus for interleaving data in a wireless communication system

Abstract

Embodiments of the present disclosure relate to methods and devices for interleaving data in a wireless communication system. For example, a method for interleaving data in a wireless communication system includes: determining the size of an interleaving array for interleaving a plurality of bits based on the number of bits to be interleaved, wherein the number of rows of the interleaving array is H and The number of columns is 2H-1; based on the size of the interleaving array, multiple bits are divided into multiple subsets; the multiple subsets are respectively written into the interleaving array, wherein the first bit in the i-th subset is written to the i-th subset Write in the position y(i, H-1) of the i-th row and the H-1 column in the interleaved array and write the subsequent bits of the first bit into the subsequent rows of the i-th row in turn, wherein at the r-th row At least two positions for writing subsequent bits include y(r, H-1-(r-i)) and y(r, H-1+(r-i)); and sequentially by columns from the interleaved array Read multiple bits written.

Description

technical field [0001] Embodiments of the present disclosure generally relate to wireless communication technologies, and more particularly, to a method, device, and computer-readable storage medium for interleaving data in a wireless communication system. Background technique [0002] On wireless communication channels, bit errors often occur in clusters, and the existing error correction technology can only detect and correct short error clusters. In order to solve the problem of bursting bit errors, interleaving techniques are usually used. Interleaving technology can rearrange the encoded bits before transmission, so that consecutive bits in the data are transmitted in a non-sequential manner. In this way, a longer error string can be redistributed into multiple shorter error strings by de-interleaving operations at the receiving device, enabling error correction techniques to correct them individually. [0003] In the latest 5G communication standard, it is proposed t...

Therefore, a triangular interleaver with a constant minimum propagation distance may not disperse erroneous bits evenly over the symbol period, resulting in degraded decoding performance
