This characteristic makes LDM a more spectral efficient system as it can use the available channel capacity for both layers with intelligent layer configuration. One such simple structure is used in the integration of LDM into advanced television systems committee (ATSC 3.0) PHY layer baseline technology [5]. In this case, a robust configuration is implemented in the upper (core) layer (UL), oriented to portable and mobile receivers. On the other hand, in the lower (enhance) layer (LL), a high-capacity configuration is chosen to deliver high data rate services, such as ultrahigh-definition television (UHDTV) or multiple high-definition television (HDTV) services, to fixed receivers. Motivated from the successful integration of LDM in ATSC 3.0, we have investigated the possibilities of convergence between the user and IoT devices based on their difference in required data rate and network condition. In our model, the UL is used to serve the IoT communications, while LL is used to serve the users (e.g., mobile handsets). As the model is developed for future wireless needs, it has to perform with user mobility. We have aimed to implement LDM UL and LL for the mobile user, which is a challenge as in ATSC 3.0, and static users are considered LL receivers. We have developed an OFDM physical layer framework to adopt LDM into our transmission model. In principle, heterogeneity for the 5G network is dictat
