An Age of Information Characterization of SPS
Maria Bezmenov, Matthias Frey, Zoran Utkovski +1
We derive a closed-form approximation of the stationary distribution of the Age of Information (AoI) of the semi-persistent scheduling (SPS) protocol which is a core part of NR-V2X…

Semantic Security with Infinite Dimensional Quantum Eavesdropping Channel
Matthias Frey, Igor BjelakoviÄ, Janis Nötzel +1
We propose a new proof method for direct coding theorems for wiretap channels where the eavesdropper has access to a quantum version of the transmitted signal on an infinite-dimens…

Simultaneous Computation and Communication over MAC
Matthias Frey, Igor BjelakoviÄ, Michael C. Gastpar +1
We study communication over a Gaussian multiple-access channel (MAC) with two types of transmitters: Digital transmitters hold a message from a discrete set that needs to be commun…
