Method and device for priority-based control and data information transmission in wireless communication system

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

• receiving, from a terminal, cancellation priority information configuring that a cancellation of a physical uplink shared channel (PUSCH) transmission is applied to the PUSCH of a specific priority;
• transmitting, to the terminal, downlink control information (DCI) for the cancellation of the PUSCH transmission, wherein the DCI includes resource information indicating time and frequency resources for the cancellation;
• and
• identifying that a reception of the PUSCH is cancelled, in case that a resource of the PUSCH is overlapped with the time and frequency resources indicated by the resource information and a priority associated with the PUSCH corresponds to the specific priority.

A terminal of a communication system, the terminal comprising:

• a transceiver;
• and
• a controller coupled with the transceiver and configured to:
• receive, from a base station, cancellation priority information configuring that a cancellation of a physical uplink shared channel (PUSCH) transmission is applied to a PUSCH of a specific priority,
• receive, from the base station, downlink control information (DCI) for the cancellation of the PUSCH transmission, wherein the DCI includes resource information indicating time and frequency resources for the cancellation,
• identify whether the cancellation is applied to the PUSCH transmission or not based on a priority associated with a PUSCH, and
• perform the cancellation of the PUSCH transmission, in case that a resource of the PUSCH is overlapped with the time and frequency resources indicated by the resource information and the priority associated with the PUSCH corresponds to the specific priority.
