Cell Partitioning Antenna System Performance in Multi-User Scenarios for mmWave Communications

Fixed-beam, high-gain antenna systems can be used for a finer partitioning of the currently cell-sectoring. This has benefit reducing number users seen per beam, which reduces interference. Furthermore, high gain allows effective isotropic radiated power while keeping transmit low. In this paper, we study performance such fixed-beam, system design millimeter-wave mobile communications. The is designed to keep inter-sector interference in multi-site scenario analyzed single- and multi-user environments. single-input single-output mode, 50th percentile signal-to-interference-plus-noise ratio lies between 12.5 dB 39.7 if 3 0 interferers are present, respectively. For multiple-input multiple-output transmission using zero-forcing, increases ranges from 36.1 43.3 interferes By maximum transmission, best achieved with no plunge observed interferers. revealed that narrow beam also provide clear signal separation small spatial separations. given example, larger than 32.1 11 active elements, where 2.8 meters separate users. Hence, paper shows cell-partitioning coverage desired area low, considered techniques situation optimized communication links.
