- Abstract
- The millimeter wave (mmWave) frequency band is being considered as a candidate for new radio bands that lead to capacity enhancement for emerging 5G mobile communication systems. But, in order to overcome propagation limitations of mmWave band, beamforming technology can be a solution and multi-beam based communication system using fixed beamforming is considered as a communication system structure for 5G mobile. In this paper, we propose inter-beam interference mitigation method for the multi-beam based 5G communication system using fixed beamforming. The proposed method mutes beams that have an effect on inter-beam interference based on proportional fair metric by beam, and improves signal to interference plus noise ratio (SINR) and system capacity.
