Advanced Distributed Algorithms for COMP in LTE networks

目前，大多数4G无线网络需要更高的容量和峰值吞吐量。LTE(长期演进)是一种新兴的无线通信标准，其目标是提高带宽利用率，爱立信加拿大公司在这一技术方面处于世界领先地位。在LTE中，协调多点(CoMP)算法致力于提高总小区吞吐量、小区边缘用户吞吐量以及小区边缘的覆盖间隙。CoMP实现的处理和控制目前是集中地或通过使用分布式处理体系结构来协调的。对CoMP使用分布式处理具有降低延迟和降低复杂性的潜力，但可能会在性能上进行权衡。我们希望将分析应用于现有的同构宏蜂窝网络以及具有小蜂窝部署的异类网络。

At present, most 4G wireless networks need higher capacity and peak throughput. LTE (Long Term Evolution) is an emerging wireless communication standard, whose goal is to improve bandwidth utilization, and Ericsson Canada is a world leader in this technology. In LTE, the Coordinated Multi-Point (CoMP) algorithms are devoted to improving the aggregate cell throughput, the cell edge user throughput, as well as the coverage gaps at the cell edges. The processing and control for CoMP implementations are currently coordinated either centrally or through use of a distributed processing architecture. Using distributed processing for CoMP has the potential of lowering latency and reducing complexity, with a possible tradeoff in performance. We want to apply analysis to both existing homogeneous macro cell networks as well as heterogeneous networks with small cell deployments.
