Device-to-Device Communications in Unlicensed Spectrum: Mode Selection and Resource Allocation
IEEE Access, 2016 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.

Journal of Computer Networks and Communications, Volume 2026, Issue 1, 2026.With the large‐scale popularity of wireless terminals, user equipment (UE) puts forward higher requirements for wireless network service quality. By using device‐to‐device (D2D) communication technology for cooperative relay transmission, any UE can be used as a potential relay UE (RUE).

Performance Enhancement of Cell Edge Users in NOMA Based Systems Using Fractional Frequency Reuse
Journal of Sensors, Volume 2026, Issue 1, 2026.Nonorthogonal multiple access (NOMA) causes significant performance loss for cell‐edge users due to strong intercell interference and fairness constraints under dense deployments. Although fractional frequency reuse (FFR) to improve dependability, especially for cell‐edge users, is widely researched, joint optimization with SINR‐based zoning and NOMA ...

Journal of Economic Surveys, Volume 39, Issue 5, Page 1971-1998, December 2025.ABSTRACT This study reports the results of a systematic literature review on auctions mechanism. Auctions are a very popular practice employed in many fields but does not exist a research that investigates the use of auctions under a cross‐disciplinary approach. This work is focused on analyzing which are the areas where auctions are mostly adopted and
