摘      要：Device-to-Device(D2D)communication is viewed as an emerging technology in the fifth generation systems to fully explore the proximate gain residing in local communicating *** the interference imposed to the existing Cellular links(C-link)should be addressed in the optimization for underlaid D2D links(D-link).There is a performance tradeoff between Energy conservation(EC)and the number of links with satisfied Quality-of-service(Qo S)requirement or System capacity(SC).We aim to weight the above tradeoff for D-links by specifying it into optimizing EC on the condition that SC is maximized and Qo S requirements of C-links are fully guaranteed.A threestage joint power control and channel assignment mechanism is proposed including feasibility check,SC maximization and greedy optimization for *** to numerical results,we illustrate the necessity to conduct our performance tradeoff and observe the gain when multiple resource variables are in elaborate cooperation.
