Patent attributes
A user equipment receives a first uplink grant and a second uplink grant from a base station. The first uplink grant assigns first uplink resources, and the second uplink grant assigns second uplink resources. The first uplink resources and the second uplink resources overlap within a time interval. The user equipment determines whether the transmission of second data has priority over that of first data. When determining that the transmission of the second data has priority over that of the first data, the user equipment determines one of the first uplink resources and the second uplink resources as the designated resources of the second data, and transmits the second data to the base station according to the designated resources within the time interval.
