Radio Resource Management for Millimeter Wave & Massive MIMO

In this post we talk about current trends oinradio resource management for massive MIMO and mm waves on wireless systems. We present some of the current trends at different research topic in PHY layer and system level analysis.

We cover some aspects of the wireless channel for mmWave.
We talk about candidate bands with nice multi-path and non line-of-sight properties for cellular communications. We mention some critical radio resource management techniques and how they can be applied for mmWaves. We discuss that for cellular communications beamforming and scheduling depend on channel estimation, the geometry of the antenna array, the transceiver architecture, and the interference from adjacent cells.

We also describe some of the main issues due to mobility and mention how centralized management can be used to avoid waste of resources and group base stations for coordinated operation. Finally , e mention some of the most promising techniques to achieve load balance in heterogeneous networks.
