Title: METHOD, DEVICE, AND EQUIPMENT FOR USE IN DETERMINING CODING AND DECODING OF POLAR CODE
Abstract:
Disclosed is a method for coding and decoding a polar code in a communication system. A basic quantitative sequence is acquired, the basic quantitative sequence comprising: a quantitative value used for expressing the reliability corresponding to a polar subchannel; a target quantitative sequence is acquired on the basis of the basic quantitative sequence, where relative magnitude relations among elements in the target quantitative sequence have nestedness with relative magnitude relations among elements of the basic quantitative sequence; the largest K quantitative values in the target quantitative sequence are determined on the basis of a non-fixed bit length K; polar subchannels corresponding to the largest K quantitative values are made as a non-fixed bit position set; and a polar code is coded or decoded on the basis of the non-fixed bit position set.
