TL;DR: It is shown that the proposed N OMA in CDRT provides remarkable performance gain compared with NOMA in non-coordinated direct and relay transmission (nCDRT); the sum capacity scaling of the proposed scheme is log ρb as signal-to-noise-ratio (SNR) ρB increases, but 1/2log ρ b for NOMa in nCDRt.

TL;DR: The achievable average rate of the proposed cooperative relaying system using non-orthogonal multiple access (NOMA) to improve the spectral efficiency is analyzed for independent Rayleigh fading channels, and its asymptotic expression is provided.

TL;DR: In this article, a method for processing a Channel State Information Reference Signal (CSI-RS) in a wireless communication system based on a multiple access scheme is provided. But, the CSI-RS transmission method defines a plurality of CSI-RSA patterns, assigns the CSI RSA patterns to individual cells, uses the CSI RSs alternately per Physical Resource Block (PRB) so as to utilize the transmission powers of all antenna ports for transmitting CSI-Rss, transmits Coordinated Multi Point (CoMP) CSI-SRSs and non-CoMP CSI-

TL;DR: In this paper, a control information transmission and reception method based on a spatial-multiplexing gain was proposed, where the common control information used for decoding the E-PDCCH was transmitted via a PDCCH, and thus, a base station supporting both a general terminal and an enhanced terminal may effectively transmit the control information.

TL;DR: The proposed D2D aided CRS using non-orthogonal multiple access (NOMA) with the power allocation is shown to improve the achievable rate greatly compared to conventional CRSs with and without NOMA, and it is proved that the sum-capacity scaling is log SNR for the proposed one, whereas (2/3) log SNr for the conventional ones.
