This application discloses a resource configuration method and an apparatus, applied to a two-level control channel structure that includes a level-1 control channel and a level-2 control channel. The method includes: obtaining, by a base station, receive bandwidth of a terminal; generating first information based on the receive bandwidth, where the first information is used for determining a frequency domain resource range used by a downlink data channel; generating second information based on the first information, where the second information is used to indicate a location of the downlink data channel within the frequency domain resource range; and sending, by the base station, the first information and the second information to the terminal.
