读懂C-RAN一C-RAN是什么?C-RAN是根据现网条件和技术进步的趋势,提出的新型无线接入网构架。
C-RAN是基于集中化处理(Centralized Processing),协作式无线电(Collaborative Radio)和实时云计算构架(Real-time Cloud Infrastructure)的绿色无线接入网构架(Clean system)。
其本质是通过实现减少基站机房数量,减少能耗,采用协作化、虚拟化技术,实现资源共享和动态调度,提高频谱效率,以达到低成本,高带宽和灵活度的运营。
C-RAN的总目标是为解决移动互联网快速发展给运营商所带来的多方面挑战(能耗,建设和运维成本,频谱资源),追求未来可持续的业务和利润增长。

RRU :远端机即射频拉远单元。
D-RoF:数字光载无线通信,利用光纤/CPRI/OBSAI传输无线信号。
CPRI(Common Public Radio Interface):通用公共无线电接口。
无线基站内部无线设备控制中心(简称REC)及无线设备(简称RE)之间主要接口规范。
第二步BBU集中化前传(FrontHaul),主要是从天线的BBU(Building Base band Unit:基带处理单元)到基站控制器RRH(Radio Remote Unit:射频拉远单元)或RRH(Remote Radio Head:射频拉远头)之间的连接。
下一代的BBU产品将支持多站点且具备专用接口以支持CoMP。
多点协作传输(CoMP:Coordinated Multiple Points Transmission/Reception)是指地理位置上分离的多个传输点,协同参与为一个终端的数据(PDSCH)传输或者联合接收一个终端发送的数据(PUSCH)。

LTESmallCell应用和部署解决方案探讨
LTE Small Cell 应用和部署解决方案探讨申建华,王擎(中兴通讯有限公司,西安710114)Small Cell 是一种低发射功率,小范围覆盖的基站设备。
Small Cell 作为3/4G 宏蜂窝的补充,能够使运营商以更低的代价为用户提供更好的无线宽带语音及数据业务。
随着LTE 网络容量的不断提升,移动运营商正在为增长的数据流量发愁,Small Cell 在这方面正扮演着越来越重要的角色,更多的Small Cell 用来覆盖盲区以及分担流量压力。
Small Cell 具有灵活、快速部署的优点,可以有效的解决热点吸收、盲点、弱覆盖场景的网络覆盖问题,实现网络无处不在。
1Small Cell 基本概念Small Cell 是低功率的无线接入节点,工作在授权的频谱,覆盖10~200m 的范围,相比之下,宏蜂窝的覆盖范围可以达到数公里。
Small Cell 的产品形态比较灵活,可分为家用Femtocell (如2×50mw )、室外Picocell (如2×1w ,室外补盲或吸热),室内Picocell (如2×125mw ,企业级室内覆盖),Microcell (如2×5w ,室外补盲或吸热)都图1宏微HetNet 组网示意图由运营商来管理。
Small Cell 可以用于室内和室外,进行覆盖补盲、热点业务吸收、提升网络容量。
Small Cell 和宏蜂窝的多个层面组成了HetNet 异构网络,通过宏微协同技术以及抗干扰技术的联合使用,网络容量可以实现数倍甚至更高幅度提升,缓解无线网络的容量压力。
宏微HetNet 组网如图1所示。
2LTE 时期Small Cell 的应用LTE 具有大带宽、高速率、低时延的特点,在LTE 网络中引入SmallCell 可以大大提升网络容量,优化网络覆盖,为用户提供更好的使用体验。
Small Cell 为LTE 带来的改变将在多方面进行应用。

Cloud RAN or Small Cells?Joe Madden, Mobile ExpertsApril 2013It’s funny to watch the industry hype machine at work. Every new idea that comes along is promoted as the “next big thing”. In the case of Cloud RAN, we have seen several vendors promoting their trials and initial deployments, and we have all heard about the savings available in baseband pooling. Cloud RAN will make dense urban networks possible, and putting the baseband processing together will make LTE-Advanced features possible.At the same time, small cells have also been advertised as the solution to the same high-density traffic problem. Instead of pooling baseband resources, small cells distribute the baseband processing. So which is it? Are we going to bring the baseband processing together, or spread it out?Both technologies are promoted as a way to save cost. The Cloud RAN architecture is intended to save operational cost, by locating everything together and allowing a technician to work more efficiently in maintaining baseband resources. Cloud RAN also enables LTE-Advanced features which improve capacity.It’s true that Cloud RAN makes LTE-Advanced easier to implement. Coordinated Multi-Point (CoMP) requires very low latency (less than 1-2 microseconds) to provide a big boost in capacity. Enhanced Inter-Cell Interference Coordination (eICIC) coordinates blank and almost-blank subframes on a real-time basis, so locating the baseband processing in one place greatly reduces the complexity of coordinating changes on the fly. The Serdes interface to a Remote Radio Head is the lowest-latency connection possible, with most of the delay coming from physical propagation instead of IPSec and processing time. As a result, multiple RRH units on a single baseband node offers the highest performance boost from CoMP..The financial benefit of CoMP comes from the added capacity and higher throughput available at the cell edges. CoMP can improve throughput by as much as 80% at the cell edge, for both uplink and downlink. Using a traditional macro network as a baseline, the overall savings can be very significant in dollar value because fewer macro eNodeBs are required. Additional savings come from the centralized location of the baseband processing, making maintenance simpler and more efficient.The Small Cell architecture is also intended to reduce cost per bit, by reducing the overall cost of baseband processing and radio hardware, as well as increasing spectral efficiency and overall throughput. Small Cells can drop the cost per bit by a factor of 4, compared to a macro LTE network. Even with high-cost backhaul such as millimeter-wave links, the cost per bit can drop in half.So which architecture gives a bigger impact to the guys in Accounting? It looks like the answer to that question is “it depends”. The Cloud RAN architecture is favored by operators with access to cheap fiber (China Mobile, NTT DoCoMo, SKT, KT), and in other cases only for stadium situations or other localized problems. The Small Cell architecture seems to be popular with most mobile operator CFOs, because the transport cost for RRH fiber outweighs the operational savings of co-locating the baseband processors. As examples, China Mobile and NTT DoCoMo like C-RAN because they own the fiber in their countries. Competitors such as China Unicom and Softbank like small cells because they pay much higher cost for fiber bandwidth.Will mobile operators discover more value in Cloud RAN when CoMP and eICIC are widely adopted? Maybe. But the Cloud RAN promoted so far doesn’t change the economics of a macro network by a factor of 4. For wider adoption, Cloud RAN must achieve some significant savings to overcome the penalty of high transport cost. At the same time, CoMP and eICIC will be implemented with small cells, and while the benefit may be smaller, we can expect significant benefits from these features in a HetNet configuration.In the end, most operators will be pushing ahead with the Small Cell architecture, and may consider Cloud RAN for special situations such as a stadium with very high density. If fiber bandwidth is free, then the cost of transport is no big deal, and Cloud RAN is attractive. For most operators around the world, fiber cost is a significant chunk of their operating budget, so we expect most of the market to move toward Small Cells.。
