For achieving high bandwidth, fast, and robust communication in 5G, multiple technologies are needed to work under heterogeneous networks. Visible light communication, due to its high bandwidth, low latency, and small interference area, will be a significant part of 5G along with mmwave. In this paper, a new frame structure has been proposed that implements reserve before transmit scheme. In this scheme, the active portion of the frame starts with contention access‐based reservation period (RP) followed by access point response (RES Reply) and TDMA‐based guaranteed time slots for successful nodes. In contrast to fixed slot assignment in TDMA, contention‐based reservation avoids idle slot wastage due to fixed allotment. Moreover, small reserve packets keep medium busy for a short time, the benefit of which is a lower probability of failed channel access. The proposed scheme has been compared with …
