2、up to 2.45 Mbps on the forward link up to 153.6 kbps on the reverse link 100% IP network Can be overlaid over an existing 1X network on a separate 1.25 MHz radio carrier Overlay over 1X allows the re-use of: 1X Metro Cell BTS (including GPS receiver, MFRM, radio antenna and duplexers) PDSN AAA serve
3、r at the PDSN2. What is 1xEV-DO Rev A? 1x = 1.25MHz, EV = Evolution, DO = Data Optimized Next evolution of 1xEV-DO Rev 0 as defined IS 856 A Supports high-speed data: up to 3.1 Mbps on the forward link up to 1.8 Mbps on the reverse link Lowers the packet data latency. Together with higher throughput
4、, it enables several commercially grade real time delay sensitive applications, e.g. VoIP, PoC. Introduces the Quality of Service (QoS) Both inter-user and intra-user QoS 100% IP network and “Always On” access Fully backward compatible with 1xEV-DO Rev 0 and CDMA 1xRTT3. What makes 1xEV-DO High Spee
5、d 前向信道全功率发射，时分复用，结合高速的信道评估和码速控制 (1xRTT) 平均的功率利用率为 50% - 60% 手机通过测量导频信号的C/I来评估前向信道，每秒钟可以报告600次最高可用数据速率（DRC）。 自适应调制方式 无线环境差，使用QPSK，无线环境优异，采用8PSK或16QAM 混合型自动重发请求Hybrid-ARQ 如果数据包在少于规定的重发次数内就成功解调，后续重发可以提前中止。 成比例公平的调度程序（ Proportional Fairness (PF) Scheduler ） PF 调度程序根据DRC/T数值进行用户调度，用户的DRC/T值越高，被分配时隙的优先级越高
6、。 4.What makes 1xEV-DO RevA more Powerful 反向信道采用自适应高阶调制，H-ARQ机制（针对Rev0上行速率没有改善的不足） 在反向引入QPSK 和8PSK调制 反向最高速率从153.6Kbps提高到1.8Mbps 通过多维调度算法，空中接口的多RLP机制， RNC和PDSN之间的多A10流，来支持端到端的QoS（针对Rev0没有QoS的不足） 根据业务类型定义不同QoS级别的IP流，映射到相应的RLP流和A10流中 时延敏感类、速率敏感类、时延不敏感类业务 建立多种机制来保证实现低时延（针对Rev0不支持实时业务的不足） 前向信道：短数据包，多用户包，
7、允许RLP不发送ACK/NACK，快速扇区切换等。 反向信道：短子帧，高速接入，快速的传输开始，功率推进传输，允许RLP不发送ACK/NACK等。 例如通过这些低时延优化，将PTT业务的建立时间从3958ms减少到827ms 二1xRTT upgrade to 1xEV-DO 1.北电现网1x网络升级至1xEV-DO演进方案2.DOM介绍 DOM-A Up to 6 DOM-As per Metrocell and cBTS 192 Channel Elements Rev-A 120 Chennel Elements Rev-0 114 links per sector Backhaul:
