Abstract

According to an aspect, a UE in an uplink split-bearer configuration is configured to transmit PDUs by a first RLC entity via a first uplink transmission path and/or by a second RLC entity via a second uplink transmission path. The UE determines a total amount of data volume from PDCP data volume and RLC data volume pending for initial transmission in the two RLC entities. The UE decides whether submission of PDCP data volume is allowed to either of the two RLC entities or to only the first RLC entity, based on whether the total amount of data volume meets or exceeds a first threshold. The UE also reports the PDCP data volume to both the first and second uplink transmission paths or only the first uplink transmission path, based on whether the total amount of data volume meets or exceeds a first threshold.
