1. A data decoding method, performed by a receiver in a wireless communication system, comprising:
receiving a signal containing Polar code data to be decoded which is transmitted via the wireless communication system;
acquiring a Polar code tree corresponding to the Polar code data to be decoded;
splitting the Polar code tree into s independent decoding sub-trees, s being an integer greater than or equal to 2;
transmitting the s independent decoding sub-trees to s pre-configured independent U value calculation modules respectively, the U value calculation modules being configured to calculate a U value required at a next iteration of a G node;
controlling each of the s independent U value calculation modules to process a respective one of the s independent decoding sub-trees to obtain s sets of new decode data; and
executing an operation reverse to splitting pre-acquired decode data into s sets of decode data, to restore the s sets of new decode data to obtain new Polar code data to be decoded.
