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