| Abstract(in English) | Mobile data traffic has increased rapidly, so many small cells will be densely overlaid on a macro cell in the 5G mobile system. For a small cell, two kinds of equipment, a centralized unit (CU) and a distributed unit (DU), are used as base stations and these are connected via optical fibers. This optical link is called as a mobile fronthaul (MFH). We have proposed a low-latency TDM-PON using a cooperative dynamic bandwidth allocation (DBA) that takes advantage of mobile scheduling information for the uplink bandwidth allocation. In this paper, we propose a solution for technical issues on the implementation of the cooperative DBA and describe latency evaluation results by the computer simulation. |
