3. 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,
wherein the target information consists of only one high-order bit of the time index information of the SS block,
wherein the parity information is information acquired through encoding first concatenate information; the first concatenate information is information acquired through concatenating combination information and first parity information corresponding to the combination information; and the combination information is information acquired through combining partial minimum system information of the NR system and the target information, the first parity information comprises CRC information, parity check information, or Hamming code check information; or
the parity information is information acquired through encoding second concatenate information; the second concatenate information is information acquired through concatenating partial minimum system information of the NR system and first parity information corresponding to combination information; and the combination information is information acquired through combining the partial minimum system information of the NR system and the target information, and the first parity information comprises CRC information, parity check information, or Hamming code check information; or
the parity information is information acquired through encoding third concatenate information; the third concatenate information is information acquired through concatenating partial minimum system information of the NR system and second parity information corresponding to the partial minimum system information of the NR system; and the second parity information is information acquired through scrambling third parity information corresponding to the partial minimum system information of the NR system by using a scrambling sequence corresponding to the target information, and the third parity information comprises CRC information, parity check information, or Hamming code check information.
