A communication method and a base station are provided, the method includes: determining, by a base station, a time length of a time domain scheduling unit, a downlink, a guard period and symbols occupied by an uplink, included in the time domain scheduling unit; generating length configuration information of the time domain scheduling unit according to the time length, the downlink, the guard period and the symbols occupied by the uplink; sending the length configuration information to a terminal through radio resource control signaling and/or downlink control information signaling, and informing the terminal of a length configuration of the time domain scheduling unit; implementing, by the base station, a communication with the terminal based on the length configuration. By utilizing the method, it is beneficial for the terminal to acquire time information of time domain resource scheduling, and utilization efficiency of time domain resources is improved.
