UPLINK IMPROVEMENT OF LONG TERM EVOLUTION ADVANCE: A SURVEY PAPER

The User Equipment's (UE) now days are able to provide different internet applications and services that raise the demand or requirement for high speed data transfer and Quality of Service (QoS). According to that, the next generation of mobile communication systems determined by these demands is expected to provide higher data rates and better link quality compared to the existing systems. In the last ten years, it has seen that significant advances of multiuser MIMO (MUMIMO) in wireless communication. MU-MIMO is now introduced in different standards or known to be as new generation wireless standards for example LTE-Advanced and 802.16m. The number of users is increasing day by day with a large number of applications and at the same time data rates with high transmission and reliability of communication are required. Additionally, growing concern is also there about the green communication which relates to the special effects of the radiation emitted from wireless devices on the human body. We introduce the basic concepts of LTE Advance uplink as well as MIMO communication and some of the literatures are introduced in this paper.
