Abstract
A relevant solution for the high demand for new multimedia applications and services is millimeter wave (mmWave) frequency band in 5G. However, in order to face the technological challenges of the present and those that will appear in the short-term future, it is necessary to improve the spectral efficiency of 5G systems. In particular, the Radio Resource Management (RRM) module is considered an essential component. Nevertheless, resource allocation techniques that combine orthogonal multiplexing (OMA) schemes, such as Time Division Multiple Access (TDMA), with Non-Orthogonal Multiple Access (NOMA) techniques have not been studied in-depth. Therefore, this article designs and evaluates different RRM models that combine TDMA with NOMA for innovative applications in the 5G mmWave frequency bands. To this end, the advantages and challenges associated with mmWave frequency bands and potential future applications are introduced. An innovative use case has been designed to test the RRM models. The use case is based on the on-demand distribution of multimedia content in high-density environments, such as museum halls. The on-demand content aims at offering Augmented Reality (AR) services to unicast users in order to provide personalized services. The models have been evaluated in terms of throughput, capacity, and availability. According to the results, the combined RRM techniques offer up to 50% more capacity than the single multiplexing technology models and can provide video-on-demand service to practically the entire cell.
