Virtual Beamforming and User Scheduling for Sub-Array Architecture in mmWave Networks.

In this letter, we propose a virtual beamforming and user scheduling technique, namely VirtualBus that attains higher beamforming gain by generating narrower beams in a sub-array mmWave network architecture. The proposed VirtualBus is beneficial as well in a sense that it does not increase the hardware complexity of the sub-array architecture. Through simulations on the practical scenario, we veri...
