Robustness of Location Based D2D Resource Allocation against Positioning Errors

Device-to-Device (D2D) communications underlaying cellular network exploits physical proximity of the devices and aims at enhancing resource utilization, coverage, data rates and Quality of Service (QOS). Further, it enables the network operators to offload conventional network routed traffic to direct peer- to-peer links and could also support new application fields, such as Machine-to-Machine (M2M) and Vehicle-to-Vehicle (V2V), communication. In order to enable D2D communication, allocating resources (Physical resource blocks: PRBs) to D2D links by reusing cellular resources is a vital procedure. There are several resource allocation (RA) schemes that facilitate resource reuse of cellular PRBs for D2D communication. In most of these schemes, the crucial information for deciding upon PRB reuse is positions of D2D pairs and cellular users, so that mutual interference can be reduced. Further, there are certain schemes that rely on angular information of users to carry out resource allocation for D2D users. Thus, accuracy of position information plays an important role for employing these RA schemes in real world. This paper discusses RA schemes that are based on position/angular information and evaluates the robustness of location based RA schemes against positioning errors in real world deployment.
