Peak-Age Violation Guarantees for the Transmission of Short Packets over Fading Channels
Paper i proceeding, 2019

We investigate the probability that the peak age of information in a point-to-point communication system operating over a multiantenna wireless fading channel exceeds a predeter- mined value. The packets are scheduled according to a last-come first-serve policy with preemption in service, and are transmit- ted over the channel using a simple automatic repetition request protocol. We consider quadrature phase shift keying modulation, pilot-assisted transmission, maximum-likelihood channel estima- tion, and mismatched scaled nearest-neighbor decoding. Our anal- ysis, which exploits nonasymptotic tools in information theory, al- lows one to determine, for a given information packet size, the physical layer parameters such as the SNR, the number of trans- mit and receive antennas, the amount of frequency diversity to exploit, and the number of pilot symbols, to ensure that the system operates below a target peak-age violation probability.
