As a key enabling technology for next generation wireless connectivity, light fidelity (LiFi) is envisioned to support seamless multi-user access. In this paper, we propose a novel time-domain based multiple access scheme referred to as index time division multiple access (I-TDMA). Our results indicate that I-TDMA provides significant spectral efficiency enhancement compared to ordinary TDMA in a two-users scenario, with minimal added hardware and computational complexity.
