Dual connectivity uplink data handling

An apparatus for wireless communication at a network node, comprising:

• one or more memories;
• and
• one or more processors, coupled to the one or more memories, configured to cause the network node to:
• transmit, to a user equipment (UE), configuration information that indicates to use data splitting or data switching for transmitting data using at least one of a first uplink connection between the UE and the network node or a second uplink connection between the UE and another network node;
• transmit, to the UE, a maximum data volume parameter that indicates a maximum data volume for the first uplink connection;
• and
• receive, from the UE, at least a portion of the data using the first uplink connection based at least in part on the configuration information and based at least in part on whether a volume of the data is greater than the maximum data volume.

A method of wireless communication performed by a user equipment (UE), comprising:

• obtaining configuration information that indicates to use data splitting or data switching for transmitting data using at least one of a first uplink connection between the UE and a network node or a second uplink connection between the UE and another network node;
• receiving, from the network node, a maximum data volume parameter that indicates a maximum data volume for the first uplink connection;
• and
• transmitting the data using at least one of the first uplink connection or the second uplink connection based at least in part on the configuration information and based at least in part on whether a volume of the data is greater than the maximum data volume.
