Abstract

The invention provides a decoding method, device and equipment, and the method comprises the steps: obtaining L1 first decoding paths of an (i-1)-th group of to-be-decoded bits, wherein i is an integer, the received data is corresponding to P groups of to-be-decoded bits, P is an integer greater than 1, 1<i<=P, and L1 is a positive integer; respectively determining a second decoding path corresponding to each first decoding path, wherein the number of the second decoding paths corresponding to at least one first decoding path in the L1 first decoding paths is different from the number of the second decoding paths corresponding to the other first decoding paths, the number of the second decoding paths corresponding to each first decoding path is less than 2n, and n is the number of information bits included in the i-th group of to-be-decoded bits; and determining at least one reserved decoding path of the i-th group of to-be-decoded bits in the second decoding paths corresponding to theL1 first decoding paths, wherein the at least one reserved decoding path comprises a decoding result of the i-th group of to-be-decoded bits. According to the invention, the coding efficiency is improved.

Description

technical field [0001] The present application relates to the field of communication technologies, and in particular to a decoding method, device and equipment. Background technique [0002] In the field of communication technologies, communication devices (such as terminal devices, base stations, etc.) can perform channel coding and decoding by means of polar codes (Polar codes). [0003] In the prior art, when decoding by polar codes, the process of decoding by a parallel method using a Serial Cancellation List (SuccessiveCancellation List, SCL) algorithm is usually as follows: the bits to be decoded are divided into multiple groups of bits, And decode each group of bits in turn. Every time one group of bits is decoded, multiple decoding paths will be expanded, and a certain number of paths will be reserved from the multiple decoding paths for the next set of decoding, and finally multiple decoding result paths can be obtained, from which A decoding result on a decoding ...
