本文介绍了在德国德累斯顿的蜂窝测试床的长期演进-高级概念的协调多点下行链路传输的测量结果。首先，描述了实时原型系统及其信号处理，介绍了对现有3GPP-LTE标准的主要修改。然后，测试床的蜂窝传播和测量环境的特点。结合合作和非合作基站以及小区中心和小区边缘场景，比较了各种空间设置。最后，有关几何因子，到达时间差和频谱效率的结果完成了现场试验。
This paper presents measurement results for coordinated multi-point downlink transmissions as Long Term Evolution - Advanced concept from a cellular test bed in Dresden, Germany. At first, a description of the real-time prototyping system and its signal processing introduces the major modifications from the existing 3GPP-LTE standard. Then, the cellular propagation and measurement environment of the test bed is characterized. Various spatial setups are compared in conjunction with cooperative and non-cooperative base stations as well as cell-center and cell-edge scenarios. Finally, results concerning the geometry factor, time difference of arrivals and spectral efficiencies complete this field trial.
