Mobile communication networks have evolved over past decade from systems providing voice and basic messaging service to an integral part of society, enabling a rich set of services from voice and video communications, internet access, banking, logistics, navigation and emergency services. A growing customer base with highly capable data centric devices has fuelled a demand for capacity in radio access networks (RAN). To meet this demand, research and development has delivered generations of radio access technologies, rolled out globally, with 4G enabling true mobile broadband experience in the UK from October 2012. The latest manifestation, 5G, being deployed globally following the completion of standardisation in 2018-2019. One of the key technological differences in 5G RAN compared to 4G RAN is native use of active antenna systems to deliver an unprecedented step change in the efficiency of use by base stations of limited spectrum resources. Active antenna systems (AAS, also known as Massive MIMO) benefit from progress in circuit and electronics technology and low cost computing power in baseband processors to provide independent control over the multiple antenna elements comprising a cellular antenna. Such finer level of control enables basestations to fine-tune transmissions to individual user conditions and to enhance the reception of transmissions by users. The net effect on user experience can be described as a perception of infinite capacity, with a user receiving the resources that their service requires and consequent enhanced responsiveness of services and applications.The challenge beyond the impressive first steps in AAS research and implementation is to be able to address emerging applications and services carrying different connectivity requirements in terms of latency, reliability, coverage and speed. Many of such new use cases including various machine-to-network communications, industrial automation and transportation, emergency and critical services will have to be provided using the same network infrastructure, including the base stations and antenna systems. No technology exploiting capabilities of AAS for such multi-service use cases exists to date since the primary driver in research and academia has been capacity and energy efficiency. A concept of 'network slicing' does not address this research challenge either since it does not consider digital signal processing and architectures of AAS.This research programme will explore and deliver a multi-service processing capability in AAS, capable of balancing reliability, coverage and overall network capacity. Specifically, we will investigate the feasibility and performance bounds of such multiservice RAN in delivering mixed types of services sustainably through a single physical infrastructure. We will identify fundamental trade-off factors between reliability and capacity achievable on physical layer of RAN with AAS, and design processing methods to effectively support user differentiation while maintaining network capacity. We will work with industry and academic stakeholders within standardisation bodies and industry to drive the identified solutions to practical realisation and shape further evolution of technology.

移动通信网络在过去十年中已经从提供语音和基本消息服务的系统发展成为社会不可或缺的一部分，支持语音和视频通信、互联网接入、银行、物流、导航和紧急服务等丰富的服务。拥有高性能数据中心设备的客户群不断增长，推动了对无线接入网络 (RAN) 容量的需求。为了满足这一需求，研发人员已经推出了几代无线接入技术，并在全球范围内推广，其中 4G 从 2012 年 10 月起在英国实现了真正的移动宽带体验。最新的表现形式是 5G，继 2018 年标准化完成后正在全球部署-2019年。与 4G RAN 相比，5G RAN 的关键技术差异之一是有源天线系统的本机使用，可在有限频谱资源的基站使用效率方面带来前所未有的阶跃变化。有源天线系统（AAS，也称为大规模 MIMO）受益于电路和电子技术的进步以及基带处理器的低成本计算能力，以提供对构成蜂窝天线的多个天线元件的独立控制。这种更精细的控制水平使基站能够根据各个用户的条件微调传输并增强用户对传输的接收。对用户体验的净影响可以描述为无限容量的感知，用户接收其服务所需的资源，从而增强服务和应用程序的响应能力。除了 AAS 研究和实施中令人印象深刻的第一步之外，挑战还在于：能够满足在延迟、可靠性、覆盖范围和速度方面承载不同连接要求的新兴应用和服务。许多此类新用例，包括各种机器到网络通信、工业自动化和运输、紧急和关键服务，都必须使用相同的网络基础设施（包括基站和天线系统）提供。由于研究和学术界的主要驱动力是容量和能源效率，因此迄今为止还没有针对此类多服务用例利用 AAS 功能的技术。 “网络切片”的概念也没有解决这一研究挑战，因为它没有考虑 AAS 的数字信号处理和架构。该研究计划将探索并提供 AAS 中的多服务处理能力，能够平衡可靠性、覆盖范围和网络整体容量。具体来说，我们将研究这种多服务 RAN 通过单一物理基础设施可持续提供混合类型服务的可行性和性能限制。我们将确定采用 AAS 的 RAN 物理层可实现的可靠性和容量之间的基本权衡因素，并设计处理方法以有效支持用户差异化，同时保持网络容量。我们将与标准化机构和行业内的行业和学术利益相关者合作，推动已确定的解决方案的实际实现，并塑造技术的进一步发展。
