Abstract

The intensification of mobile broadband services and user experience is explicitly dependent on the increased battery life of user equipment (UE) and minimized delay in service. In 5G New Radio (NR), in addition to the Discontinuous Reception (DRX) scheme, Bandwidth Part (BWP) switching plays a significant role in reducing UE power consumption. The dynamic bandwidth operation in BWP switching is power efficient as UE can adapt its operating bandwidth based on the traffic arrival. In this work, BWP switching-based DRX mechanism is modeled as an $$M^X/G/1$$ M X / G / 1 queue to trade-off between quality of service and power saving in UE in 5G NR. Analytical and numerical results on the proposed model show it to be promising in minimising power consumption and reducing delay in the service of UE.
