Disclosed in the embodiments of the present invention is a method for configuring a time-domain scheduling unit, the method comprising: a base station determining a time length of a time-domain scheduling unit, the time-domain scheduling unit comprising a downlink, a protection time slot and an uplink, the time length of the time-domain scheduling unit being 2n*5m milliseconds, and m and n being integers; configuring information transmitted by the time-domain scheduling unit according to service needs, the information transmitted by the time-domain scheduling unit comprising uplink information and/or downlink information; and setting the lengths of the downlink, the protection time slot and the uplink in the time-domain scheduling unit according to the information transmitted by the time-domain scheduling unit. Also disclosed in the embodiments of the present invention is a base station. Using the present invention may improve flexibility of time domain resource scheduling and reduce time delay of service processing.
