<p>With the advancements in finite block-length information theory, short packet communication has received significant attention in the recent years. When devices are constrained to use short packets for communication in interference limited scenarios, it is important to explore the impact of interference on the performance of the system. In this work, we consider a two-user Rayleigh fading Z-interference channel (Z-IC), where one of the users causes interference. The work obtains closed form expression for the average error and throughput for prominent interference mitigation schemes such as successive interference cancellation and joint decoding using the framework of finite block-length information theory. The developed results take into account the packet length, rate and underlying channel model. However, the average throughput generally does not take random arrival of data at the users into account. To capture this, the stability region is characterized for the considered system model which requires the determination of probability of successful decoding at the receiver. The work also explores the impact of interference on average delay and average age of information (AAoI) for various interference mitigation techniques. The developed results help to explore the interplay between packet length, average delay and AAoI for the considered system model. </p>

<p>One of the fundamental challenges in 5G and beyond technologies is to support short packet transmissions while ensuring ultra-reliable and low latency communication. Due to the distributed nature of the network, interference is almost unavoidable in most of the emerging communication scenarios. In addition to this, data arrival at the users is bursty in nature. The performance of various interference mitigation techniques for short packet communication under bursty traffic is not well understood from the existing literature. To address these issues this work considers the problem of short packet communication over two-user Rayleigh fading Z-interference channel (Z-IC) under random arrival of data at the users. The work characterizes the stability region of the 2-user Z-IC which takes account of random arrival of data at the users. The evaluation of the stability region involves determination of probability of successful decoding for the various interference mitigation techniques such as joint decoding and successive interference cancellation. The probabilities of successful decoding are characterized for various interference mitigation techniques using the framework of finite block-length information theory. The developed results take into account the packet length, rate, underlying channel model and random arrival of data at the users. The developed results also help to explore the impact of interference on average delay and average age of information for various interference mitigation techniques. </p>

One of the fundamental challenges in 5G and beyond technologies is to support short packet transmissions while ensuring ultra-reliable communication. Due to the distributed nature of the networks, such as machine-to-machine (M2M) communications, interference is unavoidable. The impact of interference on the system's performance must be better understood when users are constrained to transmit short packets. In addition, users' traffic is bursty. Thus, they may not always have data to send. This work considers a two-user Z-interference channel (Z-IC) under Rayleigh fading. The work characterizes the stability region corresponding to prominent interference mitigation schemes such as treating interference as noise, successive interference cancellation, and joint decoding schemes using the finite block-length information theory framework. The developed results consider the packet length, rate, and underlying channel model. Evaluating stability region involves determining the probability of successful decoding for the various interference mitigation techniques. The different probabilities of successful decoding are characterized for various interference mitigation techniques. These results are not explored in the existing literature in the context of Z-IC. The developed results also help to explore the impact of interference on average delay and the average age of information for various interference mitigation techniques.
