Autonomous deployment, optimization, and self-healing in beyond 4G wireless networks

我们的目标是通过统一的无线空中接口技术为新兴的路带无线服务提供无线接入。期望利用与基于LTE-Advanced的不断发展的蜂窝技术兼容的单一无线技术。在同一终端中使用单一技术而不是蜂窝和WiFi技术的混合的优势在于终端设计和网络运营的简单性和统一性。另一个主要优势是干扰管理和网络容量。从早期的蜂窝系统开始，蜂窝技术就被设计成具有固有的功率控制和干扰管理机制，这些机制比WiFi网络的效率要高得多。这种无线系统未来发展的方法认识到，在工程设计方面，LTE等无线技术相对于WiFi等技术具有强大的优势，因为它们是为访问固定基础设施而设计的，而WiFi网络主要是为ad-hoc操作而设计的，其中所有设备都是移动终端。然而，部署的WiFi网络具有非常强大的优势，例如成本较低的接入点和客户的临时部署。该项目的目标是采用蜂窝技术并增强空中接口，使其能够由用户大量部署，并由系统自主配置。自主基础设施技术愿景包含了当前的毫微微蜂窝概念，但在将常规蜂窝系统和小型蜂窝系统视为单个统一系统的意义上要笼统得多，而目前的大多数毫微微蜂窝解决方案都基于不同的网络设计方法。拟议的解决方案将对蜂窝系统的发展产生巨大影响，因为新服务将有更大的容量可用。大多数对蜂窝网络的分析通常假定系统具有某种规则的蜂窝网格和相似的小区大小。我们需要设计方法来管理这些随机部署的网络的射频载波、天线波束方向图、功率水平或小区大小以及流量调度。

We are targeting the problem of providing wireless access for emerging roadband wireless services with a unified wireless air interface technology. It is desirable to utilize a single wireless technology which is compatible with evolving cellular technologies based on LTE-Advanced. The advantage of using a single technology rather than a hybrid of cellular and WiFi technologies in the same terminal, is simplicity and uniformity in terminal design and network operation. Another major advantage is that of interference management and network capacity. Cellular technologies have been designed from the early cellular systems to have inherent power control and interference management mechanisms that are far more efficient than what can be done with WiFi networks. This approach to the future evolution of wireless systems recognizes that in terms of engineering design wireless technologies such as LTE have strong advantages over technologies such as WiFi in the sense that they were designed for access to a fixed infrastructure versus WiFi networks that were designed mostly for ad-hoc operation where all devices are mobile terminals. However WiFi networks as deployed had very strong advantages such as lost cost access points and ad-hoc deployment by customers. The aim of the project is to take cellular technologies and enhance the air interfaces to allow them to be deployed in great numbers by users and configured autonomously by the system. The autonomous infrastructuretechnology vision encompasses the current femtocells concept but is much more general in the sense that it treats the regular cellular system and the small-cells as a single unified system, whereas most of the current femtocell solutions are based on a heterogeneous approach to network design. The proposed solution will have a drastic impact on the evolution of cellular systems in the sense that much greater capacities will be available for new services. Most of the analysis for cellular networks usually assume a system of somewhat regular cellular grid and similar cell size. We need to devise approaches to manage RF carriers, antennas beam patterns, powers levels or cell size, and traffic scheduling for these randomly deployed networks.
