“…Although DBA offers the advantage of high bandwidth utilization, it requires transmission request information such as report [4] for the mobile upstream data arriving at each optical network unit (ONU) every DBA cycle, and this takes much more time than the latency requirement imposed on the MFH [5].…”

To achieve cost-effective mobile fronthaul (MFH) with a timedivision-multiplexing passive optical network (TDM-PON), we present a prototype optical-mobile cooperation interface, which converts mobile upstream scheduling information to transmission request information for the mobile upstream data that will arrive at each optical network unit (ONU). By basing bandwidth allocation on the request information converted by the interface, low-latency upstream transmission can be achieved on the MFH with the TDM-PON. We demonstrate the time spent for the conversion process in the prototype interface under various and practical conditions for the first time.

“…To reduce the latency, the mobile-scheduling-information-based DBA (mobile-DBA) can be considered [5,6]. It allocates upstream bandwidth to each ONU by using mobile upstream scheduling information (mobile-info) received from a BBU in advance instead of gathering the request information from ONUs.…”

“…In recent years, there has been a plan to densely deploy RRHs to cover a lot of user equipment (UE) with a large capacity transmission. MFH must therefore be cost-effective and the application of a time division multiplexing-passive optical network (TDM-PON) has attracted attention [3,4].…”

We propose a bandwidth allocation technique for accommodating a time division duplex mobile base station (TDD-BS) and a secondary system in a TDM-PON. Operating availability is confirmed with essential three types of TDD configuration taken from the seven types described by the Third Generation Partnership Project (3GPP) standardization group. We evaluate the latency of the TDD-BS and the throughput of the secondary system. We report that the TDD-BS signal is forwarded in less than about 50 µs and is unaffected by the secondary system. The throughput of the secondary system is improved compared with that of the conventional technique.

“…Reducing the GPT is important for reducing the DBA cycle value and latency. The latency due to DBA for FTTH services, now on the order of milliseconds [5] because of its advanced software processing to achieve strict fairness, is much larger than that required for MFH [6] and campus-LANs. Moreover, in campus-LANs, the layertwo switch has to support priority control among its ports.…”

“…To overcome these issues, previous method for 5G MFH [6] can meet the latency demand because its non-status reporting (NSR) method, which cuts of the REPORTs transmission process. However, the efficiency of bandwidth utilization with the NSR method is lower than with the SR method [7].…”

This paper proposes a new dynamic bandwidth allocation (DBA) method with low latency for campus area networks (Campus-LANs) and mobile fronthaul (MFH) based on time division multiplexing passive optical network (TDM-PON). These network systems require low latency of under 100 µs and priority control. The proposed method involves only two steps for allocation. The DBA cycle value, which is proportional to the latency, can be minimized because this method is very simple and appropriate for hardware (H/W) implementation. We implemented the proposed DBA on 10G-EPON MAC SoC and evaluated the allocation results and the latency on the 10G-EPON system. Our DBA offers ultra-low latency of 60 µs with priority control.
