N2 - In existing wireless communication systems such as cellular network, base station can become bottleneck since terminals have to exchange data traffic each other only through a base station. In order to solve this problem, device-to-device (D2D) communication has been considered. Recently, Qualcomm Inc. has introduced FlashLinQ (FLQ) for D2D communication, which has a radio frame based on orthogonal frequency division multiplex (OFDM). In FLQ, terminals distributively access to medium based on their D2D link qualities and interference from other terminals. However, terminal with low link quality can cause that other terminals excessively give up their medium access. In order to solve this problem, we propose a probabilistic medium access scheme for D2D terminals in FLQ. In the proposed scheme, terminal stochastically tries accessing to medium based on its link quality, and the excessive yieldings of other terminals are reduced. Through simulation, we evaluate performance of the proposed scheme by comparing that of FLQ. We show that the proposed scheme can improve performance of FLQ by simulation results.
