Claim 0:
1. A method performed by a terminal in a wireless communication system, the method comprising:
receiving, from a base station, configuration information including first information on a first transmission interval of a first signal scheduled for a first cell, and second information on a second transmission interval of a second signal scheduled for a second cell, wherein the first signal is associated with a first physical uplink control channel (PUCCH) and the second signal is associated with a second PUCCH;
identifying whether the first transmission interval overlaps with at least a portion of the second transmission interval in a time domain;
in case that the first transmission interval overlaps with the at least the portion of the second transmission interval in the time domain, identifying a priority between the first signal and the second signal, wherein the priority is determined based on information included in the first PUCCH and the second PUCCH;
in case that the first signal is associated with the first PUCCH including hybrid automatic repeat request (HARQ) acknowledgement/negative acknowledgement (ACK/NACK) information and the second signal is associated with the second PUCCH including channel information, determining that the second signal has a lower priority than the first signal;
identifying an uplink transmission waveform of the second signal having the lower priority than the first signal;
in case that the uplink transmission waveform of the second signal corresponds to discrete Fourier transform-spread-orthogonal frequency division multiplexing (DFT-S-OFDM), transmitting, to the base station, a non-overlapped portion of the second signal; and
in case that the uplink transmission waveform of the second signal corresponds to cyclic prefix-OFDM (CP-OFDM), the second signal is dropped.
