| description | With the overcrowded sub-6-GHz bands, millimeter wave (mmWave) bands offer a promising alternative for the next-generation wireless standard, i.e., 5-G. However, the susceptibility of mmWave signals to severe pathloss and shadowing requires the use of highly directional antennas to overcome such adverse characteristics. Building a network with directional beams changes the interference behavior, since, narrow beams are vulnerable to blockages. Such sensitivity to blockages causes uncertainty in the interfering node locations and not all of the potential interfering nodes actively contribute to the interference power level at a certain location of the network. Configuration uncertainty may also manifest in the spectral domain while applying dynamic channel and frequency assignment to support 5-G applications. In this paper, we first propose a blockage model considering mmWave specifications. Subsequently, using the proposed blockage model, we derive a spatial-spectral interference model for dense finite-area 5-G mmWave networks. The proposed interference model considers randomness of node configuration in both spatial and spectral domains. Finally, the error performance of the network from an arbitrarily located user perspective is calculated in terms of bit error rate and outage probability metrics. The analytical results are validated via Monte Carlo simulations. It is shown that considering mmWave specifications and also randomness in both spectral and spatial node configurations leads to a noticeably different interference profile. |
