Using Beamforming for Dense Frequency Reuse in 5G

Scalable D2D Communications for Frequency Reuse ≫ 1 in 5G

Proximity-based applications are becoming fast growing markets suggesting that device-to-device (D2D) communications is becoming an essential part of the future mobile data networks. We propose scalable admission and power control methods for D2D communications underlay cellular networks to increase the reuse of frequency resources and thus network capacity while maintaining QoS to all users. I...

Achieving Frequency Reuse 1 in WiMAX Networks with Beamforming

Performance Comparison Between Fractional Frequency Reuse Schemes Employing Beamforming

In this paper, the performances of using Fractional Frequency Reuse (FFR) schemes together with beamforming technique are presented. The key performances in terms of Signal-toInterference plus Noise Ratio (SINR) and channel capacity are compared. The beamforming antenna array have been both simulated and measured. The results show that the beamforming technique improves the channel capacity and...

Multilevel beamforming for high data rate communication in 5G networks

Large antenna arrays can be used to generate highly focused beams that support very high data rates and reduced energy consumption. However, optimal beam focusing requires large amount of feedback from the users in order to choose the best beam, especially in Frequency Division Duplex (FDD) mode. This paper develops a methodology for designing a multilevel codebook of beams in an environment wi...

Hybrid Beamforming for 5G Millimeter-Wave Multi-Cell Networks

Multi-cell wireless systems usually suffer both intracell and inter-cell interference, which can be mitigated via coordinated multipoint (CoMP) techniques. Previous works on multi-cell analysis for the microwave band generally consider fully digital beamforming that requires a complete radio-frequency chain behind each antenna, which is less practical for millimeterwave (mmWave) systems where l...
