Method and apparatus for controlling uplink control information in wireless communication system
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.
1. A method for transmitting uplink control information (UCI) in a wireless communication system, the method performed by a user equipment (UE) and comprising:
receiving data; and
transmitting acknowledgement/negative-acknowledgement (ACK/NACK) information for the data 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 a physical uplink control channel (PUCCH) resource is determined by a field in a downlink control information (DCI) from a PUCCH resource set pre-assigned by a higher layer signal, the periodic CSI and the ACK/NACK information are transmitted using the PUCCH resource.
2. The method of claim 1 , wherein uplink subframes in which the periodic CSI can be transmitted are predetermined by a higher layer signal.
3. The method of claim 1 , wherein the data is received through a physical downlink shared channel (PDSCH).
4. The method of claim 1 , wherein the PUCCH resource set comprises a plurality of PUCCH resources.
5. 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 receives data and transmits acknowledgement/negative-acknowledgement (ACK/NACK) information for the data 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 a physical uplink control channel (PUCCH) resource is determined by a field in a downlink control information (DCI) from a PUCCH resource set pre-assigned by a higher layer signal, the periodic CSI and the ACK/NACK information are transmitted using the PUCCH resource.
6. The UE of claim 5 , wherein uplink subframes in which the periodic CSI can be transmitted are predetermined by a higher layer signal.
7. The UE of claim 5 , wherein the data is received through a physical downlink shared channel (PDSCH).
8. The UE of claim 5 , wherein the PUCCH resource set comprises a plurality of PUCCH resources.
