Method and apparatus for handling collisions in next generation communication system

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

• transmitting, to a terminal, a radio resource control (RRC) message including information on a pre-emption related radio network temporary identifier (RNTI) dedicated for monitoring a group common downlink control information (DCI) for a pre-emption indication, information on a control resource set (CORESET) for monitoring the group common DCI for the pre-emption indication, and an offset value related to the pre-emptive indication;
• transmitting, to the terminal, the pre-emption indication by using the group common DCI in the CORESET based on the pre-emption related RNTI, wherein the pre-emption indication indicates an orthogonal frequency division multiplexing (OFDM) symbol and a physical resource block (PRB) of a resource to be used for an ultra-reliable and low latency communication (URLLC) transmission to another terminal, and the pre-emption indication transmitted in a first slot is applied to a second slot which is previous from the first slot by the offset value;
• and
• transmitting, to the other terminal, the URLLC transmission, by identifying that no downlink transmission is intended for the terminal in the resource indicated by the pre-emption indication.

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

• a transceiver;
• and
• at least one processor configured to:
• receive, from a base station via the transceiver, a radio resource control (RRC) message including information on a pre-emption related radio network temporary identifier (RNTI) dedicated for monitoring a group common downlink control information (DCI) for a pre-emption indication, information on a control resource set (CORESET) for monitoring the group common DCI for the pre-emption indication, and an offset value related to the pre-emptive indication,
• receive, from the base station via the transceiver, the pre-emption indication by monitoring the group common DCI in the CORESET based on the pre-emption related RNTI, wherein the pre-emption indication indicates an orthogonal frequency division multiplexing (OFDM) symbol and a physical resource block (PRB) of a resource to be used for an ultra-reliable and low latency communication (URLLC) transmission to another terminal, and the pre-emption indication received in a first slot is applied to a second slot which is previous from the first slot by the offset value, and
