Abstract
Two algorithms for different functional-split network models are provided, which are the CU-based (central unit based) beam allocation and admission control algorithm (CU-BAACA) and the DU-based (distributed unit based) beam allocation and admission control algorithm (DU-BAACA). Difference between the CU-BAACA and DU-BAACA includes whether the algorithm is implemented at the CU site or at the DU site. Proposed algorithms aim to optimize DUs' quality of experience (QoE) by admission control to determine the amount of data from application layer entering into traffic queue and allocating beam in physical layer at the fronthaul network between CU and DUs. On the other hand, queueing delay and queue stability are taken into consideration to maintain the system steadiness. Simulation results compare performance of two functional split models to find the appropriate scenario for each function split option, which provide technical requirement and applicability of the proposed algorithms for practical system.
