摘要：

Apart from providing high system capacity it is essential for mobile communications systems as UNITS to operate with low electromagnetic emission. Smart antennas are one promising technology to establish exposure reduction while upholding system capacity requirements. In this context, the main objective of this paper is to assess the performance improvements of practically applicable beamforming concepts for UNITS networks. The concepts illuminated are fixed as we as adaptive beamforming. To obtain suitable assessments we especially attend three essential aspects. First, proper SINR modelling is considered including spatially formed inter- / intra-cell interference as well as pilot pollution prevailing UNITS networks. Special interest is secondly given on the interaction between UMTS specific radio-resource management algorithms as power- / load control and the smart antenna concepts considered. Finally, we investigate mixed data rate traffic which is expected for UNITS. The simulations are carried out utilizing a combination of UNITS physical and dynamic system level simulators.
