Abstract
Provided is a method and an apparatus for transmitting uplink control information by a terminal in wireless communication system. When a PUCCH resource used for transmitting only periodic CSI from a subframe, the resource is a first resource, and a resource indicated by ARI is a second resource, when a setting allows transmitting together ACK/NACK and the periodic CSI through a PUCCH from the same subframe, the first resource and the second resource are mutually exclusive, and the second resource that is used for transmitting together the ACK/NACK and the periodic CSI uses the resource indicated by the ARI from resources determined by an RRC.

A method for transmitting uplink control information (UCI) in a wireless communication system, the method performed by a user equipment (UE) and comprising:
- receiving at least one data unit;
- and
- transmitting acknowledgement/not-acknowledgement (ACK/NACK) information for the at least one data unit in an uplink subframe,
- wherein when the UE is configured to simultaneously transmit periodic channel state information (CSI) and the ACK/NACK information, and when one resource for a physical uplink control channel (PUCCH) is determined by a field in a downlink control information (DCI) among a plurality of resources pre-assigned by a higher layer signal, the periodic CSI and the ACK/NACK information are transmitted using the one resource for the PUCCH.
A user equipment (UE) for transmitting uplink control information (UCI), the UE comprising:
- a transceiver for transmitting or receiving a radio signal;
- and
- a processor operatively coupled to the transceiver,
- wherein the processor is configured to:
- receive at least one data unit, and transmit acknowledgement/not-acknowledgement (ACK/NACK) information for the at least one data unit in an uplink subframe,
- wherein when the UE is configured to simultaneously transmit periodic channel state information (CSI) and the ACK/NACK information, and when one resource for a physical uplink control channel (PUCCH) is determined by a field in a downlink control information (DCI) among a plurality of resources pre-assigned by a higher layer signal, the periodic CSI and the ACK/NACK information are transmitted using the one resource for the PUCCH.
