摘要
A method of transmitting uplink (UL) control information for a user equipment (UE) for supporting a plurality of TTI lengths, a plurality of subcarrier spacing, or a plurality of processing times in a wireless communication system is performed by the UE and includes mapping the UL control information to a radio resource in a TTI including two or three symbols, the UL control information including HARQ-ACK, a rank indicator (RI), a channel quality indicator (CQI), or a precoding matrix indicator (PMI), and transmitting the UL control information to a base station, wherein, when there is no symbol to which a DMRS is mapped in the TTI, HARQ-ACK is mapped to a first symbol in the TTI in descending order from a highest frequency index resource element (RE) and the RI is mapped to the other symbol in the TTI in descending order from a highest frequency index RE.
