|1. (WO2018137511) INFORMATION TRANSMISSION METHOD AND DEVICE|
|Applicants:||HUAWEI TECHNOLOGIES CO., LTD.
|Title:||INFORMATION TRANSMISSION METHOD AND DEVICE|
An information transmission method and device, the method, applied to a network device, comprising: determining cyclic redundancy check (CRC) of information bits to be transmitted; cascading the CRC and the information bits to be transmitted so as to obtain a first information sequence; interleaving the bits in the first information sequence according to an interleaving manner or scrambling the same according to a scrambling manner so as to obtain a second information sequence, the interleaving manner or the scrambling manner being used to ensure that the bits that are in CRC positions after cyclic shift cannot check the bits that are in the positions of the information bits to be transmitted after cyclic shift; cyclically shifting the second information sequence so as to obtain a third information sequence, the cyclically shifted bits being used for carrying information of part of bits of a system frame number; and sending the third information sequence. With the embodiments of the present invention, the time delay of acquiring information by a terminal may be reduced.
