    MA-OFDM a New Multiple Access Technique for 3GPP-Defined Redcap IoT Devices
    (Konya Teknik Univ, 2025) Gültekin, Seyfettin Sinan; Hamamreh, Jehad M.; Güleç, Ülkü
    RedCap devices face challenges related to efficient multiple access techniques that can fully leverage their potential while adhering to their constraints. There are many multiple access techniques proposed in the literature recently, but none of them is deemed a good fit for the multi-facet requirements of RedCap devices. Motivated by that, this paper introduces a new multiple-access technique designed to address these challenges, aiming to optimize the performance and efficiency of RedCap devices in various application scenarios. The proposed technique seeks to enhance data rates, reduce latency, and extend battery life while maintaining the cost-effectiveness and simplicity essential for RedCap devices. Consequently, the proposed design effectively overcomes prior challenges and boosts system throughput by leveraging the power domain to transmit supplementary data bits, all while preserving a streamlined and uncomplicated transceiver design. In summary, with the same time, frequency, space, and power resources, it can be served an additional user with a stream of data bits equal to that of the main user, thus resulting in doubling the system’s spectral efficiency.
