—We consider the problem of joint power control, signal-to-noise-and-interference-ratio (SINR) target setting, mode selection and resource allocation for cellular network assisted device-to-device (D2D) communications. This problem is important for fourth generation systems, such as the release under study of the Long Term Evolution Advanced (LTE-A) system(More)
Network-assisted device-to-device communication is a promising technology for improving the performance of proximity-based services. This paper demonstrates how the integration of device-to-device communications and dynamic time-division duplex can improve the energy efficiency of future cellular networks, leading to a greener system operation and a(More)
Device-to-device (D2D) communication integrated into cellular networks is a means to take advantage of the proximity of devices and allow for reusing cellular resources and thereby to increase the user bitrates and the system capacity. However, when D2D (in the 3 rd Generation Partnership Project also called Long Term Evolution (LTE) Direct) communication(More)
—Device-to-device (D2D) communications integrated into cellular networks is a means to take advantage of the proximity of devices and thereby to increase the user bitrates and system capacity. D2D communications has recently been proposed for the 3GPP Long Term Evolution (LTE) system as a method to increase the spectrum-and energy-efficiency. Such systems(More)
