In this paper, we develop a scheduling algorithm for device-to-device (D2D) cellular networks with deadline constraints via the convex delay cost approach. At the beginning of each time slot, the algorithm allocates all available channels to the users, and each user can choose to transmit in different modes. After characterizing the transmission rates and defining the utility for each possible scheduling decision, we propose power optimization algorithms to maximize the utility for each type of decision. Our scheduling algorithm allocates each channel according to the decision that provides the maximum utility value, and it manages mode selection, channel allocation and power optimization. Via simulation results, we discuss the parameter selection for our algorithm and verify the performance improvements by allowing D2D users to share channels with other users.
