Methods, Data Split Unit and Data Collector Unit for Controlling Data Transmission Over Two Connections

A method for controlling data transmission over two connections used for communication of data from a data split unit to a data collection unit operating in a dual connection mode, the method comprising:

• obtaining a receive split ratio between the two connections as perceived at the data collection unit during the data communication,
• adapting a transmit split ratio for distributing data transmission over the two connections based on the obtained receive split ratio, and
• distributing transmission of data to the data collection unit over the two connections according to the adapted transmit split ratio.

A data split apparatus arranged to control data transmission over two connections used for communication of data from the data split apparatus to a data collection unit operating in a dual connection mode, wherein the data split apparatus is configured to:

• obtain a receive split ratio R-Rx between the two connections as perceived at the data collection unit during the data communication,
• adapt a transmit split ratio R-Tx for distributing data transmission over the two connections based on the obtained receive split ratio, and
• distribute transmission of data to the data collection unit over the two connections according to the adapted transmit split ratio R-Tx.

A method performed by a data collection unit for assisting control of data transmission of data from a data split unit over two connections to the data collection unit operating in a dual connection mode, the method comprising:

• receiving a transmit split ratio currently used for distributing data transmission over the two connections,
• measuring a receive split ratio between the two connections as perceived at the data collection unit during the data communication, and
• reporting the receive split ratio to the data split unit, depending on the received transmit split ratio, as a basis for adapting said transmit split ratio.
