  Abstract

In this paper, we develop an algorithm to manage interference in mmWave-based small cell networks. Initially, we propose a novel network architecture allowing reasonable feedback exchange and spatio-temporal power sharing. On the top of proposed architecture, we formulate a problem to maximize the utility of time-averaged user data rate by optimizing beam pattern, user scheduling, and power allocation. The problem is transformed by leveraging beam pattern selection probabilities and Lyapunov optimization, and to efficiently solve transformed problem with low complexity, we propose the IAM algorithm with sequential problem solving and critical user concept. Finally, with network topology deployed in Seoul, we show a 47.4% performance improvement over existing methods.
