Analysis of Discontinuous Reception Power Saving with Radio Resource Control States Transition in LTE Networks

چکیده
The 3GPP long term evolution(LTE) not only offer high bandwidth for data transfer but also exhaust the User Equipment(UE)’s battery life quickly. In order to save the UE’s battery Life, discontinuous reception(DRX) is specified to reduce the UE’s power consumption, DRX allow the UE to turn off RF module when there is no data need to transfer. This work focus on analysis DRX mechanism with different RRC states, we use a simple numerically analytical to model this. We divided the time period for power-saving operation into several independent parts to derive the power consumption and the transmission delay. To analysis the power advisably, we introduce the real power consumption through the power model. We evaluate the performance that the UE is more power effectively when enters RRC IDLE in lower arrival rate, and there is trade-off between the power and the transmission delay.

M2M communication is quickly gaining popularity because of its endless possibilities. In order to take advantage of this new technology we need to use more advance networks like the 3GPP LTE/LTE-A which deliver higher throughput and can handle more active devices. LTE networks were mainly designed for H2H communication meaning that we cannot just use M2M devices over it without any optimization...
