A resource configuration method, applied to a two-level control channel structure that comprises a level-1 control channel and a level-2 control channel, wherein the method comprises: obtaining, by a base station, receive bandwidth of a terminal; generating, by the base station, first information based on the receive bandwidth, wherein the first information is used for determining a frequency domain resource range used by a downlink data channel; generating, by the base station, second information based on the first information, wherein the second information is used to indicate a location of the downlink data channel within the frequency domain resource range; sending, by the base station, the first information to the terminal through the level-1 control channel, and sending the second information to the terminal through the level-2 control channel, wherein the receive bandwidth comprises at least one first resource element; the method characterized in that the generating first information based on the receive bandwidth comprises: determining, by the base station, a size of the first resource element based on the receive bandwidth; determining, by the base station based on the size of the first resource element, a location of the first resource element occupied within the frequency domain resource range; and generating, by the base station, the first information based on the location of the first resource element and the size of the first resource element. obtaining, by a base station, receive bandwidth of a terminal; generating, by the base station, first information based on the receive bandwidth, wherein the first information is used for determining a frequency domain resource range used by a downlink data channel; generating, by the base station, second information based on the first information, wherein the second information is used to indicate a location of the downlink data channel within the frequency domain resource range; sending, by the base station, the first information to the terminal through the level-1 control channel, and sending the second information to the terminal through the level-2 control channel, wherein the receive bandwidth comprises at least one first resource element; the method characterized in that the generating first information based on the receive bandwidth comprises: determining, by the base station, a size of the first resource element based on the receive bandwidth; determining, by the base station based on the size of the first resource element, a location of the first resource element occupied within the frequency domain resource range; and generating, by the base station, the first information based on the location of the first resource element and the size of the first resource element. determining, by the base station, a size of the first resource element based on the receive bandwidth; determining, by the base station based on the size of the first resource element, a location of the first resource element occupied within the frequency domain resource range; and generating, by the base station, the first information based on the location of the first resource element and the size of the first resource element.
