Truncated Channel Inversion Power Control for the Uplink of mmWave Cellular Networks

摘要

In this paper, using the stochastic geometry, we develop a tractable uplink modeling paradigm for the outage probability of millimeter wave (mmWave) cellular networks. Our model takes account of the maximum power limitation and the per-user equipment (UE) power control as well as the effect of blockages. More specifically, each UE, which could be in line-of-sight (LOS) or non-LOS to its serving base station (BS), controls its transmit power such that the received signal power at its serving BS is equal to a predefined threshold. Hence, a truncated channel inversion power control is implemented for the uplink of the mmWave cellular network. We derive expressions for the truncated outage probability and the signal-to-interference-and-noise-ratio (SINR) outage probability for the uplink of mmWave cellular networks. Our results show that contrary to the conventional ultra-high-frequency (UHF) networks there exists a slow growth region for the truncated outage probability.
