Introduction
- The increased rate demand in the upcoming 5G wireless systems and the fact that the spectral efficiency of microwave links is approaching its fundamental limits have motivated consideration of higher frequency bands that offer abundance of communication bandwidth.
- Different solutions. Cloud computing, Femtocell, Millimeter wave, etc.
- There is a growing consensus in both industry and academia that millimeter wave (mmWave) will play an important role in 5G wireless systems in providing very high data rates
- Resource Allocation and Interference Management: The directional pencil- beam operation provides many options to form different cells and allocate resources, while significantly simplifying interference management. We identify new trade-offs among throughput enhancement, fair scheduling, and formulate a suitable optimization problem based on long-term resource allocation. Finally, we use directional beams at the BSs and/or the UEs.
