A data packet for delivery to a user equipment can be inspected. Based on the inspecting, whether to use a robust downlink delivery can be determined. Based on the determining, a robust modulation coding scheme (MCS) for the data packet can be selected. The data packet can be transmitted utilizing the selected robust MCS. At least one of the inspecting, the determining, the selecting, and the transmitting is performed using at least one processor of at least one computing system. Related apparatus, systems, techniques, and articles are also described.
