Radio resource management

5G - CHALLENGES First, this vision points towards a significantly increased (in comparison to earlier generations) set of stakeholders that 5G needs to accommodate when providing communication solutions. Examples of stakeholders are:- • Individual and communities of people. • SMEs, corporations, not-for-profit and social organizations. • Digital asset owners, such as public transport and utilities authorities and organisations. • Vertical sectors like energy, health, manufacturing, robotics,

Abstract:- In the wireless communication, the radio spectrum is allocated to multiple users . But the spectrum occupied by the various wireless applications is not distributed in a uniform manner. Some part of spectrum is rarely used while other is used extensively leading to unbalanced usage of frequency spectrum. So the cognitive radio technology is used to make maximum utilization of available licensed bandwidth. It is the one of the solutions to solve the spectrum scarcity problem and supports

consumptions as in [5]. The D2D communications proposed for different time slot and same frequency used and carefully managed interference, reducing Base station traffic and minimizing transmission power. The different power saving mechanism in Radio Resource Management (RRM), power control is very important for cellular networks and beneficial to link in adaptation, interference reduction. Depending off on time of day or geographic location BS may be an idle but mobile terminal not negatively affected.

 Problem of Congestion in Cellular Network Shiva Nageswara Rao Bandereddy (sbandere@hawk.iit.edu) College of Science Department Illinois Institute of Technology, Chicago, USA. Abstract—In the next few years there will be an exponential grow in mobile data traffic due to the tremendous growth in mobile data like audio, video kind of different multimedia application. Cellular network operators invest huge amount to make their infrastructure better like installing new cell tower and offloading data

Cooperative communication is a new concept of research and it is a powerful technique to mitigate fading in wireless relaying layout. Concerning with the fading problem, this paper is focuses to give a better non-orthogonal space-time block code (STBC) scheme and assimilate it in the cooperative relaying nodes for upgrading performance of the system. Golden coded has also been incorporated in IEEE 802.16 (Wi-MAX) standard as a full rate full diversity space-time code and proven to present a ranking

cell-edge user throughput. The main purpose of this paper is to enhance the throughput of cell and , the cell-edge user’s, and the fairness among user equipment terminals (UEs) in LTE-Advanced (LTE-A) systems using CoMP In this paper we propose a resource allocation scheme for coordinated multipoint (CoMP). The transmit power is allocated to spatial layer. The transmit power is allocated to spatial layer under the total base station power constraint and the per base station power constraint Keywords

the 2.4GHz, the channel became very crowded between 2.4 to 2.485GHz, because too many electronic devices are working in this band (e.g. wireless keyboard, wireless mouse, Bluetooth and other). The crowded channel will make the equipment to seize resources. For example, we are all connected to same wireless router, everyone’s computers and routers must communicate, if only one computer, it is very simple, it can take ‘dialogue’ with router, because there

• Disadvantages: Despite the benefits that can be achieved by this technique, there are some challenges that need to be addressed, including management of the interfaces between heterogeneous environments and the dead zone problem. Towards this direction, 3GPP LTE standard has introduced Inter Cell Interference Coordination (ICIC) methods since Release 8 specifications. ICIC was developed to deal

Load Balancing in Cellular Network through Cell Breathing network structure being much dispersed, mobile AbstractIn cellular network, teletraffic continues to grow at a proliferating rate. Thus existing networks often encounter undesirable phenomenon like call drop due to overloading of cells. To overcome this problem, this thesis aims to perform load balancing using the technique of cell breathing in a novel way. Unlike previous works on cell breathing, where the radius of the overloaded cell was
