Abstract

Improving uplink behavior for a user equipment (UE) having a radio capable of communicating using at least a first radio access technology (RAT) and a second RAT. The UE may be configured to use the radio for both the first RAT and the second RAT. The UE may receive a first uplink grant corresponding to the first RAT. Prior to completing a process corresponding to the first uplink grant for the first RAT, the UE may communicate using the second RAT. After communicating using the second RAT, the UE may transmit an uplink request for the first RAT instead of completing the process corresponding to the first uplink grant.
