Abstract

The invention provides a decoding method and a related device, and the method comprises the steps: determining N estimated frequency offset values, N being a positive integer greater than 1; then, performing first decoding processing on at least one part of frozen bits of a physical broadcast channel by using the N estimated frequency offset values to obtain N intermediate decoding results of the at least one part of frozen bits; then, M candidate frequency offset values are screened out from the N estimated frequency offset values according to the N intermediate decoding results, and M is a positive integer; and finally, performing second decoding processing on the physical broadcast channel by using the M candidate frequency offset values to obtain M target decoding results. The number of assumed frequency offset values needing to be tried in frequency offset estimation can be reduced, the delay and operand are reduced, and the frequency domain synchronization efficiency is greatly improved.

Description

technical field [0001] The present application relates to the technical field, in particular to a decoding method and related devices. Background technique [0002] With the development of communication technology, the fifth generation mobile communication technology (5th Generation Mobile Communication Technology, 5G) has become more and more popular, and the user equipment (User Equipment, UE) communicates with the base station to access the 5G new air interface (New Radio, NR) network. When the UE initially accesses the NR network, the UE needs to complete time synchronization and frequency synchronization with the base station. [0003] Frequency synchronization generally adopts the method of frequency offset estimation. Usually, different UEs have different crystal oscillator schemes, and factors such as temperature drift and device aging may cause a large frequency offset with the base station. The UE crystal oscillator deviation range can reach 20ppm, for example, f...
