Problems solved by technology

[0008] Analyzing the above three methods, although they all improve the processing speed of solution rate matching to varying degrees and reduce the delay of the system, but because they all process data serially according to encoding blocks, in the case of multiple encoding blocks, the solution rate The improvement in matching processing speed is relatively limited

Abstract

The invention discloses a parallel solution rate matching generation method and a device thereof. The method comprises the following steps of: calculating the quantity of code blocks formed after code block segmentation according to the size of a transmission block, the size of a largest code block and the quantity of check bits, and determining a specific way of code block segmentation and the length Kr of each segment; determining the length Er of a rate matching output sequence of each code block according to the quantity of available bits of the transmission block; integrating a plurality of code block data of the same Kr and Er into one datum for performing solution rate matching operation; judging to perform solution repeated operation or solution punching operation according to the Kr and Er; and determining a sub-block matrix which corresponds to an initial bit and a column sequence according to the quantity of transmitted redundancy versions, orderly inputting input data into a system bit matrix and a check bit matrix, and performing sub-block de-interleaving operation. Due to the adoption of the method and the device, the processing speed of solution rate matching can be increased, and the processing time delay is reduced.

Description

technical field [0001] The present invention and the technical field of communication, in particular, relate to a method and device for parallel solution rate matching. Background technique [0002] In the communication protocol, there are detailed technical solutions for the baseband processing at the sending end, such as the realization of Turbo coding and the realization of rate matching at the sending end. At the receiving end, the agreement does not have a clear technical solution for baseband processing. For the baseband processing at the receiving end, one of the key points of implementation is to speed up the baseband processing at the receiving end, reduce the system delay, and reduce the complexity of the system. The processing speed of the solution rate matching is to achieve simple and fast processing at the receiving end a key to [0003] The function of rate matching is to adjust the code rate output by the channel encoder, so that the number of bits output b...
