Non-orthogonal multiple access (NOMA) is a promising radio access technique for the next generation (5G) cellular communication. The optimal power control, user scheduling, and resource allocation scheme to maximize the overall network throughput of downlink NOMA systems is investigated in this paper. A practical imperfect channel state information (CSI) model is adopted in our investigation where...
In this paper, an inter-cell interference coordination (ICIC) scheme for small cell networks with full-duplex (FD) base stations is proposed to maximize the overall system throughput. To be compatible with existing enhanced ICIC (eICIC) and further enhanced ICIC (FeICIC) techniques, the proposed ICIC scheme adopts cell range expansion and almost blank subframe to coordinate various kinds of interference...
In this paper, a novel technology, namely, device-to-device communications in the unlicensed spectrum (D2D-U) is proposed, which can allow D2D users to transmit on the unlicensed spectrum and coexist with the incumbent Wi-Fi networks. In D2D-U networks, D2D users can share the licensed spectrum with the existing cellular users or share the unlicensed spectrum with legacy Wi-Fi networks. Therefore,...
