UL MIMO is not much useful, because UL data will be maximum signaling, but still they allowed to use 4 * 4 MIMO. If you increase MIMO then UE capability has to be increased, you cannot have more antenna at UE side because it leads some other problems like radiations , limitation of UE capability etc.
