摘要
对U900部署的主要困难及缓冲区缩减意义进行分析,进而介绍可抑制上行干扰使U900缓冲区缩减的两种技术"窄带干扰抑制"和"底噪自动更新"的原理及应用。通过测试验证,可在案例中得到缓冲区缩减的情况下仍能保证GU目标区域覆盖效果。
This paper analyses major difficulties in the deployment of U900 and buffer reduction significance,then the two technologys “ narrow band interference suppression ” and “ background noise automatic updates” principles and applications are introduced,which can suppress uplink interference to reduce the U900 buffer. Through the test,the GU target area coverage effect can still be guaranteed in the case of the buffer reduction.
