Terminal, base station and method performed by the same in wireless communication system

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

• transmitting, to a terminal, a plurality of physical downlink control channels (PDCCHs), each PDCCH including downlink control information (DCI) that schedules a physical downlink shared channel (PDSCH);
• and
• transmitting, to the terminal, the PDSCH,
• wherein a starting symbol allocated for the PDSCH is identified based on a reference point associated with the starting symbol allocated for the PDSCH,
• wherein the starting symbol allocated for the PDSCH is relative to the reference point, and
• wherein in case that information associated with the reference point is configured, the reference point is a starting symbol of a PDCCH monitoring occasion where a latest transmitted PDCCH among the plurality of PDCCHs is located.

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

• a transceiver;
• and
• a controller coupled with the transceiver and configured to:
• receive, from a base station, a plurality of physical downlink control channels (PDCCHs), each PDCCH including downlink control information (DCI) that schedules a physical downlink shared channel (PDSCH),
• identify a reference point associated with a starting symbol allocated for the PDSCH,
• identify the starting symbol allocated for the PDSCH, that is relative to the reference point,
• receiving, from the base station, the PDSCH based on the starting symbol allocated for the PDSCH,
• wherein in case that information associated with the reference point is configured, the reference point is a starting symbol of a PDCCH monitoring occasion where a latest received PDCCH among the plurality of PDCCHs is located.

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

• a transceiver;
• and
• a controller coupled with the transceiver and configured to:
• transmit, to a terminal, a plurality of physical downlink control channels (PDCCHs), each PDCCH including downlink control information (DCI) that schedules a physical downlink shared channel (PDSCH), and
• transmit, to the terminal, the PDSCH,
• wherein a starting symbol allocated for the PDSCH is identified based on a reference point associated with the starting symbol allocated for the PDSCH,
• wherein the starting symbol allocated for the PDSCH is relative to the reference point, and
• wherein in case that information associated with the reference point is configured, the reference point is a starting symbol of a PDCCH monitoring occasion where a latest transmitted PDCCH among the plurality of PDCCHs is located.
