Description

technical field

[0001] The present invention relates to the technical field of communication, in particular to a decoding method and device, a terminal, a chip and a storage medium. Background technique

[0002] In a new generation wireless communication system (New Radio, NR), a polarized coding method is generally used for channel coding. Through channel polarization, the communication channel can be polarized into a purenoisy bit-channel and a noiseless bit-channel. Noise bit channel for transmission, and then achieve the highest transmission rate of channel transmission.

[0003] In order to improve the performance of the Polar code, the base station side mainly adopts a coding method: firstly perform Cyclic Redundancy Check (CRC) coding on the information block, and then perform polar coding on the CRC coded information block. Correspondingly, when the terminal is decoding, it needs to perform a CRC check on the code block before further implementing polar decoding. ...
