I. Introduction
Driven by industry digitization, the fifth generation (5G) technology has emerged as a powerful platform to provide services categorized in massive Machine Type Communications (mMTC), enhanced Mobile Broad Band (eMBB) and Ultra Reliable Low Latency Communications (URLLC) [1]. Among the many possible scenarios, broadcast wireless network constitute a common network scenario in the aforementioned 5G services, where a single Access Point (AP) with limited resources (such as power, spectrum etc.) serves multiple User Equipment (UE)s which may be operating with different Quality of Service (QoS) requirements. Characterizing such a network using the concept of Age of Information (AoI) alongside traditional performance metrics such as throughput and packet delay has seen growing interest in the recent times [2]. AoI is a receiver centric measure which is defined as the time elapsed since the generation of the packet that was last received at the destination [3]. This is in contrast to latency, which captures the delay experienced by a packet from entering a given protocol layer at the transmitter to exiting the same layer at the receiver. Thus, a lower arrival rate always leads to a lower latency, but the AoI may increase when the updates become too infrequent.
