Abstract
Although heterogeneous cloud radio access networks (H-CRAN) have emerged for efficient network management, resource management, and throughput enhancement, new technical challenges remain to support the urgent need to achieve full automation for ultra-low-latency connections. To simultaneously accommodate such diverse technical requirements in the HCRAN, in this article, a new paradigm of HCRAN design to significantly reduce latency is presented. From the refined radio access in the air interface, new methodology of radio resource optimization in the system architecture, and intelligent routing/paging in the backhaul, the provided foundation suggests open-loop communications and other new directions to facilitate state-of-the-art practices of the H-CRAN.
