Claim of US Patent No. 10,251,195

1. A method for performing an uplink transmission by a terminal in a mobile communication system, the method comprising:receiving, from a base station, first configuration information of a first logical channel and second configuration information of a second logical channel, the first configuration information of the first logical channel indicates whether data of the first logical channel is allowed to be transmitted on a contention based resource, and the second configuration information of the second logical channel indicates whether data of the second logical channel is allowed to be transmitted on the contention based resource;
receiving an uplink grant from the base station;
identifying that first data of the first logical channel is not allowed to be transmitted on the contention based resource based on the first configuration information, and second data of the second logical channel is allowed to be transmitted on the contention based resource based on the second configuration information;
determining whether the uplink grant is for a transmission on the contention based resource;
transmitting, to the base station, the first data of the first logical channel and the second data of the first logical channel using the uplink grant based on the determination that the uplink grant is not for the transmission on the contention based resource; and
transmitting, to the base station, the second data of the second logical channel using the uplink grant based on the determination that the uplink grant is for the transmission on the contention based resource.
