摘　　要：BBU集中化部署可有效缓解LTE建设中面临的站址获取难、建设运维成本高、能耗攀升等问题;通过进一步的BBU池组化技术还可有效提升网络性能。本文给出了BBU集中化部署的总体原则、应用场景,并针对BBU集中化部署实施中所面临的前传输纤芯资源受限、BBU机房空间受限、RRU供电、安全性、GPS天面空间受限等问题提出了包括RRU级联、大容量BBU在内的系列解决方案,可有效优化现网基站部署方案,推动移动网架构向BBU池组化方向演进。Centralized BBU deployment can effectively reduce site location requirement, lower down CAPEX/OPEX and energy consump-tion for LTE network;moreover, the multi-cellco-channel interference problem can be mitigated through further BBU pooling. It proposes the main principle, scenarios for centralized BBU deployment, and key solutions including RRU cascading and high capacity BBU in order to overcome the resource constraint problems, e.g., lack of fiber, site area, and rooftop for GPS antennas. It is envisioned that these solutions can effectively optimize today’s base station deployment strategy and propel the mobile network architecture evolving towards BBU pooling.
