Method and apparatus for transmission and reception using configured grant in wireless communication system

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

• determining a downlink resource from among a set of a plurality of downlink resources, based on a packet arrival, the remaining one or more downlink resources of the set not being configured for transmitting downlink data;
• transmitting, to a terminal, configuration information associated with the set of the plurality of downlink resources, the set being configured to occur periodically;
• and
• transmitting, to the terminal, the downlink data in the determined downlink resource.

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

• a transceiver;
• and
• at least one processor coupled with the transceiver,
• wherein the at least one processor is configured to:
• receive, from a base station via the transceiver, configuration information associated with a set of a plurality of downlink resources, the set being configured to occur periodically,
• monitor the plurality of downlink resources of the set in a period for receiving downlink data, wherein the plurality of downlink resources are monitored sequentially, and
• in case that the downlink data is received in a downlink resource of the set in the period, skip monitoring of the remaining one or more downlink resources of the set in the period.
