“…The developed results are used to explore the impact of interference on the delay and Average Age of Information (AAoI) for various interference mitigation techniques. Some of the works which consider delay and stability region under finite block-length regime can be found in [29], [30]. The work in [29] explores the benefits of NOMA in reducing queuing delay.…”

“…It has been shown that SIC may not be an attractive choice for low latency communication in case of uplink communication under channel uncertainty. The work in [30] examines the stability condition of non-cooperative timedivision multiple access (TDMA) and multiple access relay channel with TDMA scheduling and bursty traffic under finiteblock length constraint. The stability region has been considered for the two-user interference channel in [7], but it does not consider size of the packet in determining the probability of successful decoding.…”

<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>

<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>

“…To address this issue, Polyanskiy, Poor, and Verdú (PPV) [15] derived an accurate approximation of the achievable coding rate for additive white Gaussian noise (AWGN) channels within the finite block-length regime. Existing literature has been expanded to investigate the coding rate in the finite block-length regime under various situations, such as over block-fading [16], MIMO [17], relaying [18] and multi-access communication [19].…”
