Method and apparatus for performing uplink channel transmission in wireless cellular communication system

A terminal in a wireless communication system, the terminal comprising:

• a transceiver;
• and
• at least one processor configured to:
• receive, 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,
• identify 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, identify 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, determine that the second signal has a lower priority than the first signal,
• identify 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), transmit, 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.

A method performed by a base station in a wireless communication system, the method comprising:

• transmitting, to a terminal, 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) including hybrid automatic repeat request (HARQ) acknowledgement/negative acknowledgement (ACK/NACK) information and the second signal is associated with a second PUCCH including channel information;
• in case that an uplink transmission waveform of the second signal having a lower priority than the first signal corresponds to discrete Fourier transform-spread-orthogonal frequency division multiplexing (DFT-S-OFDM), receiving from the terminal, a non-overlapped portion of the second signal;
• and
• in case that the uplink transmission waveform of the second signal having the lower priority than the first signal corresponds to cyclic prefix-OFDM (CP-OFDM), the second signal is dropped,
• wherein the terminal is configured with the first cell and the second cell,
• wherein the first transmission interval overlaps with at least portion of the second transmission interval,
• wherein a priority between the first signal and the second signal is based on information included in the first PUCCH and the second PUCCH, and
• wherein the second signal associated with the second PUCCH including channel information is determined to have the lower priority than the first signal associated with the first PUCCH including the HARQ ACK/NACK information.
