In this work, we combine the two notions of timely delivery of information inorder to study their interplay; namely, deadline-constrained packet deliverydue to latency constraints and freshness of information at the destination.More specifically, we consider a two-user multiple access setup with randomaccess, in which user 1 is a wireless device with a queue and has externalbursty traffic which is deadline-constrained, while user 2 monitors a sensorand transmits status updates to the destination. For this simple, yetmeaningful setup, we provide analytical expressions for the throughput and dropprobability of user 1, and an analytical expression for the average Age ofInformation (AoI) of user 2 monitoring the sensor. The relations reveal thatthere is a trade-off between the average AoI of user 2 and the drop rate ofuser 1: the lower the average AoI, the higher the drop rate, and vice versa.Simulations corroborate the validity of our theoretical results.
