Abstract
There is provided a method of operating at least one network unit in a wireless communication system, wherein the wireless communication system comprises a first network unit and a second network unit that are both connected to a third network unit using a first connection, between the first network unit and the third network unit, and using a second connection, between the second network unit and the third network unit, wherein packets comprising the same information are transmitted over both the first connection and the second connection. The method comprises the first network unit receiving information from the third network unit indicating packets received by the third network unit from the first network unit over the first connection, and transmitting an indication to the second network unit enabling removal of packets from one or more transmission buffers of the second network unit corresponding to the indicated packets received by the third network unit from the first network unit over the first connection.
