The present invention provides a method and an apparatus for sending uplink/downlink scheduling information, and a method and an apparatus for receiving uplink/downlink scheduling information. The method for sending downlink scheduling information includes: determining, in downlink subframes on a second carrier, a first downlink subframe, in which at time corresponding to the first downlink subframe, a subframe on a first carrier is an uplink subframe; and sending, on a fifth downlink subframe on the first carrier, downlink scheduling information corresponding to the first downlink subframe on the second carrier to a terminal, in which time corresponding to the fifth downlink subframe is before the time corresponding to the first downlink subframe. The method for sending uplink scheduling information includes: determining, in uplink subframes on a second carrier, a first uplink subframe; and sending, on a sixth downlink subframe on the first carrier, uplink scheduling information corresponding to the first uplink subframe on the second carrier to a terminal, in which time corresponding to the sixth downlink subframe is before that corresponding to the first uplink subframe. The present invention achieves the purpose of performing uplink and downlink scheduling on a second carrier through a first carrier bearing a PDCCH. |
