Abstract: A solution for reliable communication in an apparatus of a communication system is provided. The solution comprises receiving (302) from a network element data packets to be transmitted to a user terminal; maintaining (304) one or more transmit buffers for transmitting data packets to the user terminal; transmitting (306) data packets to a user terminal; receiving (308) information from the user terminal regarding whether one or more data packets are successfully or not successfully received; transmitting (310) on the basis of received information acknowledgement information to another network element of the communication system; receiving (312) a notification that one or more packets have been successfully transmitted to the user terminal from a second corresponding apparatus; and, if the one or more transmit buffers comprise the successfully transmitted packets, removing (314) the packets from the buffers.
