Disclosed are a data sending method and apparatus in spectrum aggregation. When different types of cells are aggregated in downlink, the method comprises: centralizing and sending downlink hybrid automatic repeat quest (HARQ) information of the multiple cells on uplink subframes corresponding to a TDD cell among the multiple cells, the TTD cell being a primary cell, other cells being secondary cells, the uplink-downlink configuration of the main cell being X, X∈{0, 1, 2, 3, 4, 5, 6}; and configuring downlink subframes on each FDD cell for a UE, so that only on the configured downlink subframes can a physical downlink control channel (PDCCH)/a physical downlink sharing channel (PDSCH) for the UE be sent through a network, and the UE detects and receives the PDCCH/PDSCH on the configured downlink subframes. |
