Call Admission Control Optimization in 5G in Downlink Single-Cell MISO System

The main goal ofNew Radio 5G (NR) mobile technology is to support three generic service categories, each with very specific requirements. first category enhanced Mobile Broadband (eMBB), the second relates massive Machine-Type Communications (mMTC), and third ultra-Reliable Low Latency (URLLC). slicing of radio part network access has greatly contributed emergence these categories different qualities service. This division therefore enabled reserve necessary resources for services, orthogonally, according performance required. In this article, we have dealt problem Call Admission Control (CAC) in networks where considered case only two eMBB uRLLC, which their users are served by a single cell. We calculated maximum admitted into system guaranteed data rate, while allocating power, bandwidth, beamforming directions all uRLLC whose latency requirements reliability always guaranteed. downlink communication, used multiple-input single-output (MISO) system. CAC formulated as minimization l0 known NP-hard problem. chose use Sequential Convex Programming (SCP) find suboptimal solution
