Abstract
Embodiments provide a polar code encoding and decoding method in a communications system. Under the method, a basic quantized sequence can be obtained. The basic quantized sequence includes a quantized value used to represent reliability corresponding to a polarized subchannel. A target quantized sequence based on the basic quantized sequence can also be obtained. A relative magnitude relationship between elements in the target quantized sequence is nested with a relative magnitude relationship between elements in the basic quantized sequence. K largest quantized values in the target quantized sequence can be determined based on a non-fixed bit length K and polarized subchannels corresponding to the K largest quantized values can be used as a non-fixed bit position set. Polar code encoding or decoding can be performed based on the non-fixed bit position set.
