Abstract
The present invention discloses a method and an apparatus for transmitting control signaling. The method includes: determining that a physical downlink shared channel PDSCH transmission scheme for a non-backward compatible component carrier is a user equipment-specific reference signal UE RS-based non-precoding matrix indicator Non-PMI feedback transmission scheme or a UE RS-based up to 8 layer transmission scheme; and sending downlink control information DCI to a UE, where the DCI is used to indicate the determined PDSCH transmission scheme. The apparatus includes a determining module and a first sending module. The method and apparatus in embodiments of the present invention can expand application scenarios of the non-backward compatible component carrier, increase spectrum utilization of the system, and avoid a system capacity decrease problem caused by limitations on the application scenarios of the non-backward compatible component carrier.
