    摘要: The present invention discloses a method and device for transmitting downlink information in a multi-carrier aggregation system. The Method includes: a base station side sends a downlink subframe to a terminal side, wherein, the physical downlink control channel (PDCCH) in the downlink subframe is used for bearing more than one piece of downlink control indicating information and the carrier scheduling indicating information corresponding to each downlink control indicating information. It solves the problem in the prior art of indefinite identification at the terminal side because the length of DCI may be same due to the difference of the bandwidths of carriers in the carrier aggregation system.

    摘要: A method and a device for transmitting downlink information in a multi-carrier aggregation system are provided. The Method includes: a base station side sends a downlink subframe to a terminal side, wherein, the physical downlink control channel (PDCCH) in the downlink subframe is used for bearing the downlink control indicating information and the carrier scheduling indicating information corresponding to each downlink control indicating information. It solves the problem that the terminal side can not clearly identify the downlink control information (DCI) of different carriers, which is caused by that the length of DCI may be same due to the difference of the bandwidths of carriers in the carrier aggregation system.
