Beam-Aware Cross-Layer DRX Design for 5G Millimeter Wave Communication System

Beam-Aware Cross-Layer DRX Design for 5G Millimeter Wave Communication System

In the fifth-generation (5G) wireless communication system, the Discontinuous Reception (DRX) is indispensable to user equipment (UE) to support evolved technologies. However, the directionality of wireless links, especially in millimeter wave bands, leads the existing DRX mechanism to unnecessary p...
