Multi-dimensional Resource Aggregation in 5G Optical Fronthaul Networks
draft-multi-dimensional-resource-aggregation-00
Abstract
We propose a resource assignment scheme based on multi-dimensional
resource aggregation in 5G optical fronthaul networks. This new
scheme can suit to the higher demand of flexible resource allocation
of the fronthaul in the new 5G scenario.

1. Introduction
With the development of computer technology, the application of 5G
technology has become more and more extensive. For its ultra-high
transmission rate and huge data capacity, 5G technology has made
great achievements in our daily life and work. The future 5G network
will integrate artificial intelligence, SDN, NFV, and cloud computing
technologies to adapt to more and more complex application scenarios.
The 5G network architecture is totally different from the 4G network.
The application of cloud technology has emerged in the 5G network
architecture. In the traditional C-RAN, all the base station
computing resources are aggregated into the BBU pool, and distributed
radio frequency signals are collected by RRH[1][2]. Parts of the 5G
network are centralized into several clouds according to their
separate functions which are controlled to form the "three clouds"
architecture of the 5G network. The access cloud supports multiple
wireless access modes, including converged centralized and
distributed. It??s able to be adaptable in various backhaul links
and increase flexibility in the whole network. The control cloud is
used to achieve local and global session control and realize the
mobility management and QOS. It also builds an open interface for
business-oriented network capabilities. The transmit cloud improves
the reliability and reduces the latency of the whole network. It
also achieves efficient transmission of massive traffic data flow
under the control of the control cloud [3]. Moreover, compared with
the 4G network architecture, the 5G architecture separates the base
station processing unit, and reconstructs the BBU unit according to
the real-time nature of the processing content into two functional
entities which are CU and DU. The CU is mainly responsible for the
