P.karthik, S. Priyanka, G. Loganathan . Optimal Resource Allocation for Device -to-Device Communication and Minimizing the base Station Transmission Power. International Journal of Computer Applications. 111, 11 ( February 2015), 1-4. DOI=10.5120/19579-1109
The Long term Evolution (LTE) and LTE – Advanced (LTE - A) are provides the new communications such has Device to Device Communications (D2D), cellular networks direct transmission between the two are more devices. In this paper, we consider a system for D2D communication in cellular networks and minimizing the transmission power in Base station (BS). The D2D systems followed spectrum sharing protocol and Multiuser MIMO-OFDMA transmission system base station follows three power saving mechanism: Power control, Discontinuous transmission and antenna adaptation. The power control using the algorithm is known about sleep mode duration and channel knowledge. A simulation result denotes the D2D transmission versus cellular transmission and improves the system performance by reusing the cellular resources.
