为了进一步探索云蜂窝网络的协调增益，提出了部署180度扇形天线的协调半定向分布式天线系统（CS-DAS）。基于CS-DAS，建立了协同蜂窝部署结构，并设计了相应的通信流程。CS-DAS的切换过程设计具有较低的切换速率和信令开销。推导了遍历容量和能量效率的系统性能，重点分析了下行链路性能，并与当前蜂窝结构进行了比较分析。通过改进协调增益，得到了遍历容量的数值表达式。并对不同传动方式下的能效进行了研究。仿真结果验证了性能的改进。
In order to further explore the coordination gain from the cloud cellular network, the Coordinated Semidirectional Distributed Antenna System (CS-DAS) is proposed with deploying 180-degree sector antennas. Based on the CS-DAS, the coordinated cellular deployment structure is established with corresponding communication procedure designs. The handover process for CS-DAS is designed with less handover rate and signaling overheads. The system performances of ergodic capacity and Energy Efficiency are derived, with a strong focus on the downlink performances, and analyzed with comparisons of current cellular structure. The numerical expressions of ergodic capacity are obtained with improvements of coordinated gain. The Energy Efficiency with different transmission modes is also investigated. The simulation results verify the performance improvements.
