【Abstract】 Due to the randomness of device-to-device(D2 D) users’ mobility, D2 D links may suffer from connection loss or co-channel interference. To improve the stability of D2 D links, a link state prediction based resource allocation and mode selection algorithm is proposed, which adjusts users’ power level, transmission frequency and transmission mode according to the predicted link state. Simulation results show that the proposed algorithm can effectively reduce the chances of abnormal links and improve the link stability.更多还原
