Uplink control information transmitting method and apparatus

An uplink control information (UCI) transmission controlling method, comprising:

• performing, by a base station, secondary cell index (SCellIndex ) configuration for a secondary carrier, wherein when the base station configures multiple carriers for a UE, the base station configures that a SCellIndex of a carrier in a licensed spectrum is smaller than a SCellIndex of any carrier in an unlicensed spectrum, or performs scheduling configuration for the UE, wherein the scheduling configuration includes preferably scheduling transmission on a carrier in a licensed spectrum in an uplink subframe where the UE has a possibility to transmit UCI, or preferably scheduling transmission on a licensed carrier for triggered aperiodic Channel State Information (CSI) when the base station triggers the UE to transmit the aperiodic CSI;
• transmitting, by the base station, a SCellIndex configuration signalling according to the configuration, or transmitting an uplink (UL) grant according to the configuration.

An uplink control information (UCI) transmission controlling base station, comprising:
