Abstract
The invention relates to the field of communications and provides a method of and apparatus for transmitting downlink control information, and the method includes: for transmission of DCI over any carrier, determining DAI information fields in uplink scheduling DCI and downlink scheduling DCI to be carried over the carrier and an HARQ process number information field in the downlink scheduling DCI dependent upon PDSCH HARQ feedback scheme currently in use; and determining a UL index information field in the uplink scheduling DCI to be carried over the carrier dependent upon a PUSCH scheduling scheme currently in use, so that an appropriate DCI design scheme is provided for an application scenario of across-system carrier aggregation to thereby satisfy a demand for the use of an evolved process in an LTE system and improve effectively the performance of the system.
