The proposed FOFDM-IDMA platform has two focal points: first, it enables the coexistence of various time-frequency granularities suitable to diverse service groups, and second, it supports massive connectivity with low latency to provide reliable communications. Thus, the proposed FOFDM-IDMA framework can simultaneously support the requirements of uRLLC (ultrareliable low-latency communications) and mMTC (massive machine-type communications) for the next-generation communication systems. However, the 5G new radio (NR) can solely support the requirements of uRLLC and mMTC independently. Simulation results show that the proposed FOFDM-IDMA platform performs remarkably well, compared to the conventional scheme in the IoT environment.
