Location-based Resource Allocation for mobile D2D communications in multicell deployments

Cooperative intelligent traffic systems (C-ITS) will help improve the safety and efficiency of ground transportation by enabling the cooperation between traffic participants. Applications based on the C-ITS paradigm rely on vehicle-to-vehicle, vehicle-to-infrastructure, and vehicle-to-device (collectively, V2X) communication for the exchange of critical information and have very stringent Quality of Service (QoS) requirements on the reliability and availability of the communication links. In order to enable V2X communication using the envisioned device-to-device underlay of future 5G cellular networks, we have introduced a Location Dependent Resource Allocation Scheme (LDRAS) in [1]. In this paper, we enhance and extend LDRAS to multicell deployments, and quantify its performance based on extensive system level simulations. The results show that LDRAS significantly improves the QoS for future C-ITS applications, from radio resource management point of view. However, satisfying the requirements of such services necessitates further improvements of 5G networks over current 4G deployments.
