Method and apparatus for transmitting control information in a wireless communication

摘要

The present invention relates to a wireless communication system. More particularly, the present invention relates to a method for transmitting acknowledgement/negative ACK (ACK/NACK) in a wireless communication system which supports carrier aggregation, and to an apparatus for the method. A method in which a terminal transmits ACK/NACK in a wireless communication system that supports carrier aggregation comprises the following steps: receiving one or more physical downlink shared channels (PDSCHs); and transmitting ACK/NACK for said one or more PDSCHs via a physical uplink control channel (PUCCH). A PUCCH format for transmitting ACK/NACK is selected by taking the type of the carrier in which said one or more PDSCHs are received into account.

1. A method for transmitting uplink control information at a User Equipment (UE) configured with a plurality of Component Carriers (CCs) including a Primary CC (PCC) and a secondary CC (SCC) in a wireless communication system, the method comprising:
receiving one or more physical channel signals in a subframe, wherein each of the one or more physical channel signals requires Acknowledgement/Negative ACK (ACK/NACK) feedback, and the one or more physical channel signals include at least one of one or more Physical Downlink Shared Channel (PDSCH) signals and one or more Physical Downlink Control Channel (PDCCH) signals indicating Semi-Persistent Scheduling (SPS) release; and transmitting ACK/NACK information for the one or more physical channel signals via a Physical Uplink Control Channel (PUCCH), wherein when only a single physical channel signal is received on the PCC, the ACK/NACK information is transmitted using a first PUCCH format, and wherein when at least one physical channel signal is received on the SCC, the ACK/NACK information is transmitted using a second PUCCH format.
