1. A method of transmitting and receiving a signal by a communication device in a wireless communication system, the method including:
configuring an interlace including M resource blocks (RBs) and N symbols for transmission of a physical uplink control channel (PUCCH); and
based on that an actual uplink control information (UCI) payload size required for the PUCCH transmission is smaller than a maximum UCI payload size capable of being transmitted on a PUCCH resource, transmitting the PUCCH by selecting a minimum number (Nmin) of symbols required for the PUCCH transmission among the N symbols,
wherein the minimum number of symbols are selected to be adjacent to a location of demodulation reference signal (DMRS) symbols, and
wherein transmission of DMRS symbols not located first in a time domain among the DMRS symbols adjacent to the minimum number of symbols is dropped.
