DRX and DTX Algorithms at BS and UE for Minimum Power Consumption in LTE Network

Vaibhav Gaikwad, Manish Sharma, Trupti Wagh

Abstract


Power in any cellular network is a key degree in management of connectivity, energy factors, speed etc. In LTE network the power consumption is dominated at evolve node. To compute this issue a mechanism has been proposed to reduce the power consumption at evolve node. This issue is tackled by discontinuous transmission (DTX) mechanism where the evolve node is switched off for specified amount of time when there is no occurrence of packet. Also as the resources of user equipment are limited, discontinuous reception can be used to have proper power consumption. These issues are simulated with busty traffic condition which is represented by Poisson’s traffic condition with exponential distribution for insensitive traffic. Thus power consumption is calibrated at evolve node as well as UE in LTE network.
