摘　　要：随着2G退网,将有15 MHz无线频率资源可用于FDD900部署。为充分发挥900 MHz频段优势,最大程度激发无线资源效益,夯实4G打底网容量基础,满足用户使用需求,本文提出了FDD900 15 MHz单载波组网、10 MHz+5 MHz双载波组网和10 MHz+5 MHz载波聚合3种资源分配方案,重点从体验速率、终端支持和资源投入3个方面探讨了FDD900 15 MHz单载波组网、10 MHz+5 MHz载波聚合组网的可行性,并针对不同场景,给出了相应的组网建议。With 2G withdrawal of service,there will be 15 MHz frequency resources available for 4G FDD900.In order to fully utilize the advantages of the 900 MHz frequency band,maximize the benefits of wireless resources,consolidate the capacity foundation of the 4G base network,and meet user needs,this paper proposes FDD900 15 MHz single carrier networking,10 MHz+5 MHz dual carrier networking,and 10MHz+5MHz carrier aggregation three resources allocation schemes.The feasibility of FDD900 15 MHz single carrier networking,and 10 MHz+5 MHz carrier aggregation are discussed from Internet speed,mobile terminal support and resources investment.And corresponding networking suggestions are given for diff erent scenarios,to provide network optimization solutions for practical work.
