Abstract

A polar code decoding method and device, wherein the method includes: determining the value of the sequence parameter of the polar code, the sequence parameter of the polar code includes the length of the encoded input bit sequence and the length of the rate matching output sequence; based on pre-stored The data structure of the polar code determines the position of the information bit of the polar code corresponding to the value of the sequence parameter of the polar code; and performs polar code decoding according to the position of the information bit of the polar code. In the embodiment of the present application, the pre-stored data structure can be used to represent the position of the K information bits of the polar code corresponding to each of the various values ​​of the sequence parameters of the polar code. Therefore, based on the pre- The stored structure can directly determine the position of the information bit of the polar code corresponding to the value of the sequence parameter of the polar code, and then there is no need to re-adjust the operation during the decoding process, which can effectively simplify the decoding process. And improve the decoding efficiency.

Description

technical field [0001] The present application relates to the field of communication technologies, and in particular to a polar code decoding method and device. Background technique [0002] The rapid evolution of wireless communication indicates that the fifth generation (5G) communication system will present some new features in the future. The three most typical communication scenarios include enhanced mobile Internet (enhance mobilebroadband, eMBB), mass machine connection communication (massive machine type communication, mMTC) and ultra reliable low latency communication (ultra reliable low latency communication, URLLC), the requirements of these communication scenarios will pose new challenges to the existing long term evolution (LTE) technology. As the most basic wireless access technology, channel coding is one of the important research objects to meet the needs of 5G communication. [0003] Polar codes are selected as the control channel coding method in the 5G st...
