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

我们的目标是为新兴的路带无线服务提供无线接入的问题与统一的无线空中接口技术。期望利用与基于高级LTE的演进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技术的混合的优点是终端设计和网络操作的简单性和一致性。 另一个主要优点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网络所能实现的效率高得多。这种对无线系统的未来演进的方法认识到，在工程设计方面，诸如LTE的无线技术相对于诸如WiFi的技术具有很强的优势，因为它们被设计用于访问固定基础设施，而WiFi网络主要被设计用于ad-hoc操作，其中所有设备都是移动的终端。然而，所部署的WiFi网络具有非常强的优势，例如接入点的成本损失和客户的自组织部署。该项目的目的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。自治基础设施 技术愿景包括当前的毫微微小区概念，但是在它将常规蜂窝系统和小小区视为单个统一系统的意义上更一般，而大多数当前毫微微小区解决方案基于网络设计的异构方法。 所提出的解决方案将对蜂窝系统的演进产生巨大影响，因为更大的容量将可用于新服务。大多数蜂窝网络的分析通常假设一个有点规则的蜂窝网格和类似的细胞大小的系统。我们需要设计方法来管理这些随机部署的网络的RF载波、天线波束模式、功率电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 infrastructure technology 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.
