Scl parallel decoding method and apparatus and device

Abstract

Example successive cancellation list (SCL) parallel decoding methods and apparatus are described. One example method includes obtaining L1 first decoding paths of an (i−1)th group of to-be-decoded bits after received data corresponds to P groups of to-be-decoded bits, where i is an integer, P is an integer greater than 1, 1<i≤P, and L1 is a positive integer. L3 third decoding paths is determined for each first decoding path, where a quantity of information bits in an ith group of to-be-decoded bits is n, n is a positive integer greater than or equal to 1, L3 is a positive integer, and L3<2n. At least one reserved decoding path of the ith group of to-be-decoded bits is determined from L1×L3 third decoding paths, where the at least one reserved decoding path includes a decoding result of the ith group of to-be-decoded bits.
