摘要：

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 power consumption. In this paper, we first identify the problems of beam pattern mismatching. Then, we proposed a dynamic beam-aware DRX mechanism, which could be applied along with dynamic mmWave beam configuration. The proposed framework jointly optimizes beam-aware DRX operation and dynamic mmWave beam configuration for better energy efficiency. A semi-Markov model is proposed to evaluate a UE sleeping ratio and packet delay. The simulation validates the proposed model. Compared to the baseline 5G NR DRX operation, the proposed scheme achieves 41.6% improvement in the sleep ratio without sacrificing the packet delivery latency performance.
