Abstract This paper studies the interference graph construction problem for device-to-device (D2D) communications underlaying cellular networks. Firstly, an improved interference graph construction method compared to the previous work in Zhang et al. (IEEE Trans Vehicular Technol 66(4):3293–3305, 2017) is proposed. The difference is mainly that, in this work the BS allocates resources for transmitting probe packets for links in a centralized manner; while in the previous work the links select resources for transmitting probe packets in a random and autonomous manner. With this “BS-allocation” method, the BS can obtain more useful information about the interference graph than the previous “random allocating” method. Secondly, this work proposes a new theoretical analysis metric, i.e., the missing rate; while previous work analyzed the traditional convergence time. This difference is caused by that this work considers the dynamic scenario in which cellular and D2D links arrive to and leave the cell dynamically, while the previous work considered the static scenario. When considering dynamic scenario, it is possible that the interference graph has changed before the BS completes the graph construction. Hence, we must evaluate the accuracy of the constructed interference graph, i.e., the missing rate, for dynamic scenario. Simulation results validate the theoretical analysis and show that the proposed method outperforms existing methods. The impact of parameters on the missing rate is also investigated.

1 Introduction Cellular device-to-device (D2D) communications refers to the technology which enables a pair of user equipment (UEs) in cellular networks to communicate directly without going through the base station (BS) [1,2]. A major concern with D2D data transmission is the interference caused by D2D links. Assume D2D transmission uses the uplink spectrum. There are three types of interferences: interference between D2D transmission and cellular reception, interference between cellular transmission and D2D reception, and interference between D2D transmission and D2D reception. To mitigate these interferences, various techniques can be employed [3]. The first idea appeared in the literature was to control interference through power management, i.e., to set the transmit power of D2D links appropriately so that the

interferences are controlled under tolerable level. For example, in [4], a power control and resource allocation scheme was proposed for maximizing sum rate subject to spectral efficiency restrictions. In [5], an interference limited area control scheme was proposed to manage interference from cellul
