<p>A network node (120) initiates a multicast transmission of a data item via a cellular network to a plurality of devices (10). Associated with the multicast transmission, the network node (120) provides a request that at least a subgroup of the devices (10) each send a report indicating whether an action on the basis of the data item received by the device (10) was successfully completed by the device (10). Depending on the reports, the network node (120) adjusts the repeated multicast transmission of the data item.</p> |
