Abstract
Methods, systems, transmitters, receivers, network elements and software applications in a system for acknowledging the reception of sets of data objects, wherein one or more transmitters transmit one or more sets of data objects within respective point-to-multipoint transmission sessions to a plurality of receivers, and wherein repair requests and/or delivery verification reports are transmitted by at least one of said receivers to network elements within point-to-point transmission sessions. Different back-off times are assigned for delivery verification reports and repair requests, at least two delivery verification reports of one receiver are jointly transmitted within one point-to-point transmission session, and a delivery verification report is transmitted after a completed repair session within the same point-to-point transmission session used by the repair session. Furthermore, a minimum set of parameters to be sent in delivery verification reports is shown.
