Method and apparatus for transmitting control signaling

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