Abstract
In order to further improve the system performance under device-to-device(D2D) communication, considering the reuse of D2D mode is a very promising way. However, involving the reuse mode will make the design of scheduling scheme at the base station (BS) side even more challenging. This work focuses on the design of a scheduling scheme involving multiplexing relay D2D mode for the base station which jointly considers the user's requirements of service quality and delay comprehensively, and proposes a cross-layer joint scheduling algorithm aiming at maximizing the transmission rate of the whole system. We formulate such a scheduling issue into a mathematical optimization problem, and then we decompose the problem into three sub-problems according to power allocation, channel allocation and mode selection, and solve them respectively. The simulation results verify the importance of considering the multiplexing relay D2D mode and the influence of some main parameter Settings on the delay and transmission rate of the system, which provides a reference value for improving the transmission rate of the system by changing the parameter of the system.
