FDD Missive MIMO物理层设计方案及实现
|
摘要
随着第四代(4G)移动通信系统的持续发展,4G用户的逐渐增加和上网模式的变化,使得现网网络负荷越来越重,各种不限量套餐也给网络容量和用户感知带来了新挑战。FDD Massive MIMO将5G的技术提前应用到4G,通过大规模天线阵列和波束赋形,可以使不同用户共享相同的频谱资源,大大提升了频谱效率,释放了用户的移动数据需求。通过多个外场商用局的验证,频谱效率可以给现网带来70%～80%的增益。
With the continuous development of the fourth-generation(4G) mobile communication system, the gradual increase of 4G users and the change of the Internet access mode make the load of the existing network more and more heavy, and various unlimited packages also present new challenges for network capacity and user perception. FDD Massive MIMO applies 5G technology to 4G in advance. Through large-scale antenna array and beam-forming, different users can share the same spectrum resources, greatly improving spectrum efficiency and releasing users' mobile data requirements. Through the verification of multiple field commercial bureaus, the spectrum efficiency can bring 70% to 80% gain to the existing network.
