摘要
伴随着用户量的高增速,用户感知度对网络的覆盖、容量和质量提出了新的挑战。FDD-LTE网络作为中国联通4G主要承载网络,随着4G用户的不断增加,网络容量受到严重挑战,稀缺的FDD-LTE频率资源成为网络进一步扩容的瓶颈。FDD-LTE所需的成对频谱越来越难获得。在FDD网络受限的情况下合理利用TDD-LTE频率资源,解决热点区域扩容瓶颈,已成为最优解决方案。
With the rapid growth of user number,user perception proposes new challenges to network coverage,capacity and quality.FDD-LTE network is the main bearer network of China Unicom 4G,With the increasing number of 4G users,the network capacity has been severely challenged.The rare FDD-LTE frequency resources have become the bottleneck of further expansion of the network.The paired spectrum required by FDD-LTE is becoming more and more difficult to obtain.In the case of limited FDD network,it is the best solution to rationally utilize TDD-LTE frequency resources and solve the bottleneck of hot spot expansion.
