Wireless connectivity is currently considered a de-facto capability, enabling people and machines to communicate. Range of applications supported by such Radio Access Networks (RAN) ranges from voice and video calling, content streaming services, banking, cloud data storage, navigation and many more. The volume of data carried by cellular networks delivering the connectivity for such applications grows approximately by 40% every year, which means the data traffic approximately doubles every two years, according to Ofcom. Research and development effort within industry and academia has been focussed on technologies capable of meeting this growing demand for capacity, delivering innovations in digital signal processing, computer science, optical transmission, circuitry, and antenna technology. Spectral efficiency, which is the amount of information that can be carried in a radio channel, has been the key focus for such inter-disciplinary effort since radio spectrum is a scarce resource and has to be used efficiently. Active Antenna Systems (AAS, also referred to as Massive MIMO) is the latest generation of base station technology for mobile networks delivering increased spectral efficiency by combining innovations and experience from multiple disciplines. AAS are already being rolled out as part of 5G network deployments globally and will continue to play a key role in future generations of mobile networks. However, in order for investment in mobile networks to be viable, more services need to be able to use mobile network efficiently, calling for support for multiple services to be concurrently delivered over the same cellular infrastructure. Practical potential of AAS to concurrently deliver multiple services is the focus of the original FLF.Sustainability has emerged as a key theme in recent years with a view to reduce carbon emissions by a substantial amount to help reverse the negative impact of industrialisation on the climate. In mobile networks this has resulted in energy efficiency (EE) becoming a key design objective. With 0.8% of the overall UK energy consumption falling on BT network alone, finding both short and long-term solutions to this challenge is of critical importance. The specific challenge for RAN is to minimise the consumption of electrical power while also meeting increasing demand for diverse connectivity services.This project will focus on ambitious enhancements to practical mobile network. The aim of the renewed fellowship is to increase the practical EE of diverse connectivity services provided by mobile networks - from traditional delivery of bits over the wireless interface, to provision of non-data bearing services such as positioning. To achieve this goal, the project will establish practical EE benchmarks for data and service provision in current mobile networks, and then assess and develop approaches to improve the EE, both in short and long term. Specifically, technologies such as muting of transmitters, sending base stations to varying states of sleep will be considered as reference capabilities available in short term, while the use of AI to tailor transmission technology and the use of energy-efficient waveforms with be considered as longer-term research objective aiming the development of 6G air interface.Applications and benefits from this project will include benchmarks for EE gains from key technology choices under practical operating conditions and constraints. This will enable a realistic assessment of potential contribution to sustainable RAN, and also help design EE-native communication and network deployment strategies for 5G and 6G RAN.

目前，无线连接被认为是事实上的功能，使人和机器能够进行交流。此类无线电访问网络（RAN）支持的应用程序范围从语音和视频通话，内容流服务，银行，云数据存储，导航等等。根据Ofcom的数据，蜂窝网络携带的数据量每年可增长约40％，这意味着数据流量每两年大约翻了一番。行业和学术界内部的研发工作一直集中在能够满足能力需求不断增长的技术上，为数字信号处理，计算机科学，光学传输，电路和天线技术提供创新。光谱效率是可以在无线电通道中携带的信息的数量，它一直是这种跨学科工作的重点，因为无线电频谱是一种稀缺的资源，必须有效地使用。主动天线系统（AAS，也称为大型MIMO）是最新一代的基站技术，用于通过结合多个学科的创新和经验来提高光谱效率的移动网络技术。 AAS已被全球5G网络部署的一部分推出，并将继续在子孙后代的移动网络中发挥关键作用。但是，为了使移动网络的投资可行，更多的服务需要能够有效地使用移动网络，呼吁支持多种服务以及在相同的蜂窝基础架构上同时提供。 AAS同时提供多种服务的实际潜力是原始FLF的重点。近年来，人们已经成为一个关键主题，目的是将碳排放量减少大量，以有助于扭转工业化对气候的负面影响。在移动网络中，这导致能源效率（EE）成为关键设计目标。仅在BT网络上，英国整体能源消耗的0.8％仅在BT网络上就下降了，因此为这一挑战提供了短期和长期解决方案至关重要。 RAN的具体挑战是最大程度地减少电力消耗，同时还满足对各种连通性服务的不断增长的需求。该项目将重点放在实用移动网络的雄心勃勃的增强上。重新奖学金的目的是增加移动网络提供的各种连接服务的实际EE（从传统的无线界面上的位传递到提供非DATA轴承服务（例如定位）。为了实现这一目标，该项目将在当前的移动网络中为数据和服务提供建立实用的EE基准，然后评估和开发改善EE的方法，无论是在短期还是长期的。具体而言，诸如发射机突变，向不同睡眠状态发送基站的技术将被视为短期内可用的参考功能，而使用AI来量身定制传输技术以及使用能节能的波形使用具有长期研究目标的使用为6G空气界面的开发。从该项目中效益。将在此项目中效益。这将使对可持续发展的潜在贡献进行现实评估，并帮助设计EE本地的沟通和网络部署策略5G和6G运行。
