Device-to-Device Communications in Cellular NetworksIntroduction

Device-to-Device Communications in Cellular Networks: Introduction [The proliferation of smart phones in the past decade has contributed to the improvement of productivity and lifestyle quality. Modern-day life now depends heavily on ubiquitous wireless access world with high speed and high quality data transmission.

To confront these and related challenges, the third generation partnership project (3GPP) long-term evolution (LTE) continues to standardize technologies with higher data rates, lower latency, and lower power consumption. Presently, LTE-Advanced (LTE-A) supports new technology components for LTE to meet wider range of communication service requirements [1, 2].

Abstract

[The proliferation of smart phones in the past decade has contributed to the improvement of productivity and lifestyle quality. Modern-day life now depends heavily on ubiquitous wireless access world with high speed and high quality data transmission. On the other hand, such widely spread use of cellular devices leads to an explosive growth of wireless traffic volume, severely straining the limited cellular bandwidth and capacity. To confront these and related challenges, the third generation partnership project (3GPP) long-term evolution (LTE) continues to standardize technologies with higher data rates, lower latency, and lower power consumption. Presently, LTE-Advanced (LTE-A) supports new technology components for LTE to meet wider range of communication service requirements [1, 2]. Device-to-Device (D2D) communication, as a technology component for LTE-A, allows direct wireless links between mobile users without routing data through a base station (BS) or the core network. Given the rapid growth of data traffic, the shortage of radio spectrum, and the pressing need for battery energy consumption, D2D communications can bring some benefits compared to the conventional infrastructure-based communication. The direct benefits include improved system throughput, increased spectrum efficiency and energy efficiency, and reduced transmission delay, etc.]
