Disclosed are an information transmission method, a base station, a user equipment and a communication system. The transmission method comprises: determining a time window for enhanced transmission of first information, wherein content of the first information transmitted in the time window does not change and the first information is any one among MIB, SIB1, SIB2, first control information for scheduling the SIB1 and second control information for scheduling the SIB2; and sending the first information in the time window and repeatedly sending the first information in the time window for multiple times, wherein when the first information is the MIB, the number of times for repeatedly sending the MIB in the time window is greater than 4; when the first information is the SIB1, the number of times for repeatedly sending the SIB1 in the time window is greater than 4; when the first information is the SIB2, the number of times for repeatedly sending the SIB2 in the time window is K and the K is a fixed integer that is greater than 1; or when the first information is the first control information or the second control information, the number of times for repeatedly sending the first control information or the second control information in the time window is greater than 1. Implementing the present application can perform enhanced transmission of the MIB, the SIB1, the SIB2, the control information for scheduling the SIB1 or the control information for scheduling the SIB2, improving reliability in transmitting system information and control information. |
