Long Term Evolution Advanced (LTE-Advanced) is the next step in LTE evolution and allows operators to improve network performance and service capabilities through smooth deployment of new techniques and technologies. LTE-Advanced uses some new features on top of the existing LTE standards to provide better user experience and higher throughputs. Some of the most significant features introduced in LTE-Advanced are carrier aggregation, enhancements in heterogeneous networks, coordinated multipoint transmission and reception, enhanced Multiple Input Multiple Output (MIMO) usage and deployment of relay nodes in the radio network. Mentioned features are mainly aimed to enhance the radio access part of the cellular networks. This survey article presents an overview of the key radio access features and functionalities of the LTE-Advanced radio access network, supported by the simulation results. We also provide a detailed review of the literature together with a very rich list of the references for each of the features. An LTE-Advanced roadmap and the latest updates and trends in LTE markets are also presented.

“…As a result, the channel gains can be assumed to be perfectly known by the receivers [18][19][20][21][22][23][24][25][26][27][28][29][30][36][37][38][39][40][41]. On the other hand, there is no CSI available at the BSs (CSIT), except the HARQ feedback bits.…”

This paper investigates the performance of coordinated multi-point (CoMP) networks in the presence of hybrid automatic repeat request (HARQ) feedback. With an information theoretic point of view, the throughput and the outage probability of different HARQ protocols are studied for slow-fading channels. The results are compared with the ones obtained in the presence of repetition codes and basic HARQ, or when there is no channel state information available at the base stations. The analytical and numerical results demonstrate the efficiency of the CoMP-HARQ techniques in different conditions.

“…It is also called as Evolved-Universal Mobile Telecommunication System Terrestrial Radio Access (E-UTRA) and known as 4th Generation (4G) of mobile radio technologies which is increasing the spectral efficiency, peak data rate, higher throughput. The Coordinated multi-Point transmission system is an essential technology for 4th generation (4G) cellular system [2] and [3]. This technique can interrupt the intra-cell, the inter-cell inference and improve the cell edge throughput [4].…”

Lately, interference cancellation is a hard challenge in a cellular communication system. In this paper, we consider the interference cancellation using logic OR gate from the multiple input multiple output (MIMO) interference channel where each transmitter and receiver equipped with single or multiple antennas. In our system, we have used a threshold logic unit which is operated by logic OR with NOT operation in the MIMO receiver for interference cancellation. The threshold unit has two logic threshold signals which are separated by two vectors. These two logic thresholds are denoted by High and Low signal in the threshold unit. The High and Low signals are represented by the desired and interference signal, respectively. Our approach is to practically achieve interference alignment and absolutely cancel to the interference from the received signal by using logic OR operation in the MIMO receiver. General TermsInterference, MIMO transmitter and receiver, logic OR and NOT operation, threshold unit. KeywordsSystem model; interference alignment; interference cancellation using logic OR gate operation.
