MIMO Technologies in 3GPP LTE and LTE-Advanced

Multiple input multiple output (MIMO): 


Technologies introduced in LTE such as spatial multiplexing, transmit diversity, and beam forming are key components for providing higher peak rate at a better system efficiency, which are essential for supporting future broadband data service over wireless links. Further extension of LTE MIMO technologies is being studied under the 3GPP study item “LTE- Advanced” to meet the requirement of IMT-Advanced set by International Telecommunication Union Radio communication Sector (ITU-R).
