An information reception method for a User Equipment (UE) in a NR system, comprising:

• performing reception detection on an SS block, to acquire a first transmission signal mapped to a first Orthogonal Frequency Division Multiplexing (OFDM) symbol, a second transmission signal mapped to a second OFDM symbol, and parity information carried by a PBCH;
• performing channel estimation on the first transmission signal and the second transmission signal, to acquire a phase difference between the first transmission signal and the second transmission signal;
• acquiring to-be-checked target information in accordance with the phase difference;
• and
• checking the to-be-checked target information in accordance with the parity information,
