Method and device for determining transmission time in wireless communication system

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

• a transceiver;
• and
• a processor configured to control the transceiver to:
• identify a first physical downlink control channel (PDCCH) that schedules a first physical downlink shared channel (PDSCH),
• identify a second PDCCH that schedules a second PDSCH, and
• receive the first PDSCH and the second PDSCH that are at least partially overlapped at least in time, in case that the first PDCCH scheduling the first PDSCH and the second PDCCH scheduling the second PDSCH are associated with different control resource sets (CORESETs).

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

• transmitting, to a terminal, a first physical downlink control channel (PDCCH) that schedules a first physical downlink shared channel (PDSCH);
• transmitting, to the terminal, a second PDCCH that schedules a second PDSCH;
• and
• transmitting, to the terminal, the first PDSCH and the second PDSCH that are at least partially overlapped at least in time, in case that the first PDCCH scheduling the first PDSCH and the second PDCCH scheduling the second PDSCH are associated with different control resource sets (CORESETs).
