In this paper, a quality of experience (QoE)- oriented beam management and admission control (AC) problem is investigated with consideration of time-varying channels and delay requirement for different functional split (FS) millimeter (mm)-wave fronthaul networks. The original problem aims to maximize time-averaged QoE of distributed units (DUs) with co-existence of short-term and long-term constraints, which makes the considered problem intractable. By leveraging Lyapunov optimization technique, the formulated problem is converted into a series of AC and beam allocation (BA) problems. Two AC and BA (ACBA) algorithms are proposed to solve the converted problem based on whether it is implemented at central unit (CU-ACBA) or DU (DU-ACBA). Simulation results demonstrate technical insights and applicability of the proposed algorithms by indicating the appropriate scenario for each FS option (FSO).
