Comparative Performanceof Subcarrier Schedulers in Uplink LTE-A under High Users' Mobility

Ali Othman, et. al.
2015 International Journal of Computing and Digital Systems  
This paper evaluates the effects of high mobility of Users Equipment (UEs) on the performances of different data rate services using four scheduling algorithms in the uplink of LTE system using the uplink Vienna simulator.The uplink reports Channel Quality Indicator (CQI), Precoding Matrix Indicator (PMI) and Rank Indicator (RI) to inform the evolved node base station (eNodeB or eNB) about the current channel state. We simulate 20 and 30 UEs switch at high mobility and different service
