Abstract:
1. A method for transmitting control information using Physical Uplink Control Channel PUCCH) format 3 by a communication apparatus in a radio communication system, comprising: detecting a Physical Downlink Control Channel (PDCCH) signal; receiving a Physical Downlink Shared Channel (PDSCH) signal corresponding to the PDCCH signal on a secondary cell (SCell); and determining one or more PUCCH resources among a plurality of PUCCH resources configured by a higher layer for the PUCCH format 3, wherein the one or more PUCCH resources are indicated by a value of a transmit power control (TPC) field of the PDCCH signal, wherein, if a single antenna port transmission mode is configured, the value of the TPC field is mapped to a PUCCH resource n wherein, if a multi-antenna port transmission mode is configured, the value of the TPC field is mapped to the PUCCH resource n
