| Popis: | In this paper, we consider an OFDM(A) based millimeter wave (mmWave) system that is derived from a 5x scaling of the LTE numerology and incorporates analog beamforming-based antenna systems at both the access point (eNB) and user equipment (UE). We characterize the performance of such a system via a single- and multi-user link budget analysis as well as detailed system simulations. The sensitivity of performance to inter-site distance (ISD) and indoor vs. outdoor UEs is evaluated. A key observation is that while mmWave systems can achieve high throughputs, especially for dense deployments, outage is a concern for indoor UEs and non-line-of-sight (NLoS) channels. This motivates the need to build in robustness in mmWave access systems design. An analysis of the throughput impact of in-band backhaul for delivering efficient end-to-end service in ultra-dense mmWave networks is shown. Optimal resource partitioning approaches are derived that yield design guidelines for dense network deployments with in-band backhaul. |
