Abstract	Long Term Evolution-Advanced (LTE-Advanced) and other advanced technologies like IEEE802.16e and IEEE802.11g base their physical layer transmission on multiple input multiple output (MIMO). The concept of multiple antennas at both receiver and transmitter ends is attributed with advantages of spatial multiplexing and diversity, however, the Implementation on small size UEs has its own limitations. Hence a concept of virtual multiple input multiple output (VMIMO) has evolved to accommodate higher throughput for LTE-Advanced system. This paper formulates a scheme that provides maximum uplink throughput in LTE-ADVANCED environment keeping minimum level of fairness within grouped user equipment (UEs) in VMIMO. Groups/Pairs are formed from single antenna UEs to obtain multiplexing gain. Round Robin (RR), Proportional Fair (PF) and Random Pairing (RP) are Conventional pairing scheme. Fairness is prime consideration in RR and PF but RP ignores both fairness and throughput. In this paper, a Modified Random Pair (M-RP) has been introduced that maximizes throughput 2.10%, 2.07% & 2.02% in Lower group VMIMO and .96%, .96% & .95% Higher group VMIMO from RP, RR and PF respectively while keeping minimum level of fairness in the legal UEs within Femtocell scenario.
