Method and device for performing uplink status report for low latency in next-generation mobile communication system

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

• transmitting, to a terminal, logical channel configuration information including first information on an allowed configured grant for each of at least one logical channel;
• and
• receiving, from the terminal, a first configured grant,
• wherein the first configured grant is allowed to a first logical channel and a second configured grant is allowed to a second logical channel based on the first information, and
• wherein the first configured grant is transmitted based on the first configured grant being considered a prioritized configured grant, in case that an uplink grant for the first configured grant and an uplink grant for the second configured grant are overlapped.

A terminal in a wireless communication system, comprising:

• a transceiver;
• and
• a processor configured to:
• receive, via the transceiver from a base station, logical channel configuration information including first information on an allowed configured grant for each of at least one logical channel,
• identify a first configured grant allowed to a first logical channel and a second configured grant allowed to a second logical channel, based on the first information,
• identify that an uplink grant for the first configured grant and an uplink grant for the second configured grant are overlapped, and
• transmit, via the transceiver to the base station, the first configured grant having a priority that is higher than a priority of the second configured grant.
