Abstract

The invention provides a decoding method, device and equipment and a storage medium. The method comprises the following steps: demodulating a received current synchronization signal block to obtain current soft bit information corresponding to the current synchronization signal block; sorting the N prediction scrambling codes corresponding to the N prediction bit values based on the current soft bit information to obtain N sorted prediction scrambling codes; wherein N is the second power of 2; obtaining ith descrambling information based on the ith prediction scrambling code in the sorted N prediction scrambling codes; wherein i is a positive integer greater than or equal to 1 and less than or equal to N; and decoding the ith descrambling information to obtain an ith decoding result, and when the ith decoding result passes the verification, taking the ith decoding result as the decoding result of the current synchronization signal block, and ending the decoding of the current synchronization signal block. According to the invention, the decoding power consumption can be saved, and the decoding efficiency can be improved.

Description

technical field [0001] The present application relates to mobile communication technology, and in particular to a decoding method, device, equipment and storage medium. Background technique [0002] At present, when the terminal obtains the system information of the cell on the broadcast channel of the 5G NR (5th-Generation New Radio) cell, it needs to receive the PBCH packet on the physical broadcast channel (PBCH, Physical Broadcast Channel). Since the scrambling code used by the sending end in the PBCH packet is unknown to the terminal, when the channel condition is not good, the terminal usually needs to blindly descramble the PBCH packet one by one according to all the possibilities of the scrambling code, and then according to the blind descrambling The descrambling result is decoded in the next step, and finally it is verified whether the decoding result is normal. Therefore, the terminal usually needs to go through multiple descrambling and decoding to finally obtai...
