This application discloses a resource determining method, a base station, and a user equipment. The method includes: determining a first narrowband resource available to an MTC terminal according to UE information in a random access process and/or common information of a cell; and transmitting control information and/or data on the first narrowband resource. According to the solutions of this application, in a case where the MTC terminal cannot receive RRC signaling, the narrowband resource available to the MTC terminal can still be determined beforehand, and communication between the MTC terminal and a network-side device is implemented by using the narrowband resource.
