Delay and Peak-Age Violation Probability in Short-Packet Transmissions [PDF]
2018 IEEE International Symposium on Information Theory (ISIT), 2018 This paper investigates the distribution of delay and peak age of information in a communication system where packets, generated according to an independent and identically distributed Bernoulli process, are placed in a single-server queue with first-come first-served discipline and transmitted over an additive white Gaussian noise (AWGN) channel. When
