US 9,432,977 B2 · Apparatus and method for transmitting uplink control information

Abstract

A wireless communication system is disclosed. A method and apparatus for allowing a user equipment (UE) to transmit uplink control information through a physical uplink shared channel (PUSCH) are disclosed. A method for allowing a UE to transmit uplink control information through a PUSCH in a wireless communication system includes receiving configuration information about a plurality of PUSCH feedback modes, identifying information indicating a specific PUSCH feedback mode for the PUSCH by using uplink allocation information for the PUSCH, and transmitting the uplink control information through the PUSCH in accordance with the specific PUSCH feedback mode.

A method of transmitting aperiodic channel status information (CSI) at a user equipment (UE) through a physical uplink shared channel (PUSCH) in a wireless communication system, the method comprising:

receiving radio resource control (RRC) configuration information about a plurality of component carrier sets for aperiodic CSI reporting,
wherein at least one of the plurality of the component carrier sets includes two or more component carriers;
receiving a physical downlink control channel (PDCCH) signal for scheduling the PUSCH,
wherein the PDCCH signal includes a 2-bit value indicator, and a value of the 2-bit value indicator indicates only one of the plurality of component carrier sets for which aperiodic CSI reporting is triggered only for CSI feedback through the PUSCH scheduled by the PDCCH signal;
and
transmitting aperiodic CSI for the indicated one of the plurality of component carrier sets only through the PUSCH scheduled by the PDCCH signal.
