II-New: TurboRAN: Testbed for Ultra-Dense- Multi-Band Control and Data Plane Split Radio Access Networks of the Future

新兴的下一代（5G）蜂窝网络的一个关键要求是它们必须快速适应广泛的用例。这个问题要求蜂窝无线电接入网络架构的设计和操作方式发生重大转变。一种前进的方式是探索新颖的无线电接入架构，诸如控制和数据平面分离架构（CDSA），并且为它们配备下一代主动自组织网络功能（P-SON）。在这种方法下，小型小区可以在毫米波段上操作，并且按需向用户提供高数据速率。 在低于6千兆赫（GHz）频带上操作的覆盖宏小区提供控制功能以支持这些用户，同时提供较低的数据速率。为了将这种方法转化为实用的架构和解决方案，需要专门构建的测试平台，因为大多数现有的测试平台不具有研究CDSA和P-SON的灵活性和端到端可编程性。该项目将开发TurboRAN：未来超密集多频带控制和数据平面分离无线电接入网络的测试平台，旨在满足这些需求。 TurboRAN的影响包括：1）实现对P-SON、CDSA及其变体的实验研究，以及5G无线系统及以后的各种其他系统级方面，并获得可再现的结果; 2）验证无线社区进行的基于理论和仿真的系统研究; 3）在多层蜂窝网络中提供对蜂窝系统控制和用户平面的开放访问; 5）测试新的方法和协议，以开发原型并缩短研究周期，实现快速商业化轨道; 6）制定学术界与产业界的联合计划，开展旨在快速生产和促进标准的研究，从而发挥创新门户的作用。该项目由俄克拉荷马州大学的团队领导，并与众多国内外学术界和行业合作伙伴共同致力于推动未来蜂窝系统的实验研究。TurboRAN将包括三层蜂窝，支持在6 GHz以下频段和毫米波频段运行，并采用传统的异构和C-RAN实现。它将支持MIMO、移动的接入点和用户设备的多样性。除了端到端的可编程性和灵活性，可以对各种未来异构蜂窝系统场景进行建模外，TurboRAN项目的另一个独特功能是集成的大数据处理能力，可以探索尚未开发的蜂窝控制和用户平面数据的潜力，以设计主动的下一代自组织网络。

A key requirement from emerging next-generation (5G) cellular networks is that they must be rapidly adaptable to a broad range of use cases. This problem calls for a big shift in the way cellular radio access network architectures are designed and operated. One way forward is to explore novel radio access architectures such as Control and Data Plane Split Architecture (CDSA), and equip them with next generation Pro-active Self-Organizing Network functions (P-SON). Under this approach, small cells may operate on millimeter wave bands and provide high data rates to users on demand. Overlaid macro-cells that operate on sub-6 Gigahertz (GHz) frequency bands provide control functions to support these users while providing lower data rates. To translate this approach into pragmatic architectures and solutions, there is a need for a purpose-built testbed, as most existing testbeds don't have the flexibility and end-to-end programmability to investigate CDSA and P-SON. This project will develop TurboRAN: Testbed for Ultra-Dense-Multi-Band Control and Data Plane Split Radio Access Networks of the Future that aims to meet these needs. Impacts of TurboRAN include: 1) Enabling experimental research on P-SON, CDSA, and its variants, among various other system-level aspects of 5G wireless systems and beyond, with reproducible results; 2) Validating theoretical- and simulation-based systems research conducted by the wireless community; 3) Providing open access to cellular system control and user planes in a multi-tier cellular network; 4) Training a generation of wireless engineers leveraging innovative and experimental teaching; 5) Testing novel approaches and protocols for developing prototypes and shortening the research cycle towards rapid commercialization trajectory; 6) Developing joint academic-industry programs for conducting research aimed at rapid production uptake and promoting standards and thus acting as an innovation gateway. The proposed project is led by the team at The University of Oklahoma in conjunction with a number of domestic and international academic and industry partners interested in facilitating experimental investigation on future cellular systems.TurboRAN will comprise three layers of cells, supporting operation in sub-6GHz bands as well as in millimeter wave bands, with conventional heterogeneous as well as C-RAN implementation. It will support MIMO, mobile access points and diversity of user devices. In addition to end-to-end programmability and flexibility for modelling a variety of futuristic heterogeneous cellular system scenarios, another unique feature of the TurboRAN project will be the integrated big data processing capability to explore the potential of untapped cellular control and user plane data for designing a proactive next-generation self-organizing network.
