Multi-cell interference coordinated scheduling in mmWave 5G cellular systems

Abstract

The traffic demand is increasing drastically, and millimeter wave (mmWave) bands have the potential to offer much higher throughput due to broad spectrum. We have two main contribution under urban NLOS mmWave cellular system. First, an orthogonality concept is used in spatial-time domain resource allocation to perform the scheduling, which gives consideration to throughput and fairness. Second, we focus on the mac layer design that can deal with the inter-cell interference at the same time. We proposed a mechanism that can allow some cooperation between adjacent cells. In this way, we are able to eliminate interference and preserve the high spatial reuse feature of mmWave signal.
