Management of Uplink Bitrates

One or more network nodes of a wireless communication system configured to manage bitrates for dedicated radio bearers (DRBs) for a user equipment (UE) served by two or more distributed transmission units, the DRBs including at least one DRB terminating at a first control unit and at least one DRB terminating at a second control unit, the one or more network nodes comprising:

• communication circuitry;
• and
• processing circuitry operatively associated with the communication circuitry and configured to:
• determine at least a first uplink aggregated maximum bit rate (UL AMBR) value for the UE for the first control unit and at least a second UL AMBR value for the UE for the second control unit;
• and
• signal the first UL AMBR to the first control unit and signal the second UL AMBR to the second control unit, for enforcement by the first and second control units.

One or more network nodes of a wireless communication system configured to manage bitrates for dedicated radio bearers (DRBs) for a user equipment (UE) served by two or more distributed transmission units, the DRB s including at least one DRB terminating at a first control unit and at least one DRB terminating at a second control unit, the one or more network nodes configured to act as a first control unit and comprising:

• communication circuitry;
• and
• processing circuitry operatively associated with the communication circuitry and configured to:
• receive signaling indicating at least a first uplink aggregated maximum bit rate (UL AMBR) value for the UE;
• and
• enforce the first UL AMBR value for the UE.
