An embodiment of the invention provides an information transmission method and device, and an information receiving method and device. The sending method comprises the following steps: first according to the length of the message, to determine the cyclic redundancy check CRC code length, wherein the first information for the control of information, if the first information length is less than or equal to the first threshold value to determine the length of the CRC code for the first length, or, if the first information the length is less than or equal to the first threshold value and the threshold value is greater than second, it is determined that the length of the CRC code for the first generation of polynomial length; according to the length of the CRC code and corresponding to the first information, CRC code generation; second generation information; sending the information second. The invention improves the reliability of information transmission.
