Apparatus and method for determining timing relationship in wireless communication system

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

• a transceiver;
• and
• at least one processor coupled to the transceiver, wherein the at least one processor is configured to:
• receive, from a base station, first configuration information including a plurality of first values associated with a first slot offset between physical downlink control channel (PDCCH) and physical downlink shared channel (PDSCH) and second configuration information including a plurality of second values associated with a second slot offset between PDCCH and physical uplink shared channel (PUSCH),
• receive, from the base station, first control information including information for identifying a first minimum value among the plurality of first values and a second minimum value among the plurality of second values,
• receive, from the base station, second control information including information associated with the second slot offset, and
• transmit a PUSCH to the base station based on the second control information.

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

• transmitting, to a terminal, first configuration information including a plurality of first values associated with a first slot offset between physical downlink control channel (PDCCH) and physical downlink shared channel (PDSCH) and second configuration information including a plurality of second values associated with a second slot offset between PDCCH and physical uplink shared channel (PUSCH);
• transmitting, to the terminal, first control information including information for identifying a first minimum value among the plurality of first values and a second minimum value among the plurality of second values;
• transmitting, to the terminal, second control information including information associated with the second slot offset;
• and
• receiving a PUSCH from the terminal based on the second control information.

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

• a transceiver;
• and
• at least one processor coupled to the transceiver, and configured to:
• transmit, to a terminal, first configuration information including a plurality of first values associated with a first slot offset between physical downlink control channel (PDCCH) and physical downlink shared channel (PDSCH) and second configuration information including a plurality of second values associated with a second slot offset between the PDCCH and physical uplink shared channel (PUSCH);
• transmit, to the terminal, first control information including information for identifying a first minimum value among the plurality of first values and a second minimum value among the plurality of second values;
• transmit, to the terminal, second control information including information associated with the second slot offset;
• and
• receive a PUSCH from the terminal based on the second control information.
