description: The emergence of delay-constrained applications imposes stringent latency and reliability requirements in 5G and beyond 5G networks, necessitating a shift in the performance analysis of networks from the infinite blocklength assumption to finite blocklength. Since the blocklength in the finite blocklength regime (FBR) imposes a trade-off between delay, reliability, and information coding rate, the performance analysis under infinitely long codes would be less applicable in practical scenarios. This dissertation presents a novel mathematical framework to characterize the performance of large-scale networks employing short codewords providing tractable expressions, conducts comparisons with the performance in the infinite blocklength regime characterizing the gap between the two regimes which motivates the importance of the proposed work, and investigates the effect of network and transmission parameters (e.g. base-station density, power allocation, power control parameters) on the performance. In the analysis, we consider orthogonal multiple access (OMA) and non-orthogonal multiple access (NOMA) networks. For the large-scale OMA uplink and downlink (DL) networks, theoretical achievable rates, outage probability, reliability, and the coding rate meta distribution are derived using finite blocklength coding theory and stochastic geometry. Moreover, achievable rates under practical modulation schemes and multilevel polar coded modulation (MLPCM) are investigated. Numerical results provide theoretical performance benchmarks and highlight the potential of MLPCM in achieving close to optimal FBR performance. For large-scale DL NOMA networks with a two-user cluster, the work proposes inner and outer bounds on the achievable rate region in the FBR, characterizes the min-max rate, and investigates the impact of parameters such as code-length and network density on their performance. The MLPCM is also investigated and the results validated its compliance for future technologie…
