Transmitting device and method performed therein for handling communication

Abstract:

Embodiments herein relate to a method performed by a transmitting device (120) for handling communication in a wireless communications network, wherein the transmitting device (120) comprises at least two radio link control, RLC, entities and is configured with a split bearer to a receiving device (100). The transmitting device (120) identifies that a last transmitted protocol data unit, PDU, of one of the at least two RLC entities, is lacking a poll indicator requesting a status of one or more transmitted PDUs. When identifying that the last transmitted PDU lacks the poll indicator, the transmitting device transmits to the receiving device (100), a PDU comprising a poll indicator.
