摘要
Disclosed is a method for realizing downlink control information for optimizing an uplink HARQ, comprising the following steps: setting at least two independent cells in downlink control information, the data type of each cell being a bitmap, wherein the number of bits in a first cell is the number of uplink component carriers scheduled for user equipment, and the sequence of the bits indicates the index of the component carriers; the number of bits in a second cell is the number of transmission blocks transmitted over all the uplink component carriers scheduled for the user equipment; each component carrier corresponds to at least one and at most two transmission blocks, and the sequence of the bits indicates the index of the transmission blocks. Compared with the prior art, the present invention can effectively solve PHICH collision, and improve the feedback efficiency of UL HARQ ACK/NACK and the blind detection efficiency of downlink control information.
