Abstract
Example information transmission methods and devices are disclosed. One example method is applied to a network device and includes determining CRC bits of to-be-sent information bits, concatenating the CRC bits and the to-be-sent information bits to obtain a first information sequence, and interleaving bits in the first information sequence in an interleaving manner or scrambling the bits in the first information sequence in a scrambling manner, to obtain a second information sequence, to ensure that bits at locations of the CRC bits after a cyclic shift cannot check bits at locations of the to-be-sent information bits after the cyclic shift. A cyclic shift is performed on the second information sequence to obtain a third information sequence, where a quantity of cyclically shifted bits is used to carry information about some bits of a system frame number, and the third information sequence is sent.
