Abstract

The future wireless network aims to accommodate new forms of services arising from the large-scale inclusion of the internet of things (IoT). This inclusion of IoT and ever-increasing users will require the future network to possess higher system capacity and manage heterogeneity in the service requirement. Layer division multiplexing (LDM) is a potential technology that can enhance network capacity by taking advantage of this inherent heterogeneity of future wireless networks. This chapter presents a transmission framework where the LDM layer serves IoT-user pairs. The IoT devices are served using an LDM upper layer (UL), and the users are served using a lower layer (LL). We have developed a physical layer model incorporating LDM and tested its performance for the intended usages scenario. Both UL and LL performance show the capability to serve IoT devices and users to justify our proposed transmission scenario. Mobility management for LDM LL is a crucial challenge as it was initially developed for static receivers. Moreover, the mobility of both IoT devices and the user impacts the LDM pair sustainability. To test our system’s robustness against receiver mobility, we have developed an analytical model to test the link sustainability for LDM pairs when both receivers have different levels of mobility. We have also included massive multiple-input multiple-output transmission and beamforming in the system model, focusing on the future wireless network. For simulation, we have considered three different mobility models for both types of receivers, and link sustainability for LDM pairs belonging to different mobility groups is compared to determine the more suitable LDM pair from receiver mobility. The achieved results show that LDM can enhance the system capacity in future wireless networks.
