1. A method of transmitting a physical uplink control channel (PUCCH) signal by a user equipment (UE) in a wireless communication system, the method comprising:receiving a plurality PUCCH resource configurations comprising (i) a number of symbols used for a corresponding PUCCH signal, and (ii) symbol index information related to the corresponding PUCCH signal, respectively, via a higher layer signaling;
receiving downlink control information (DCI) related to a certain PUCCH resource configuration among the plurality of PUCCH resource configurations; and
transmitting the PUCCH signal based on the certain PUCCH resource configuration determined based on a combination of (i) the higher layer signaling and (ii) the DCI,
wherein a slot index related to the PUCCH signal is determined based on the DCI.
