Abstract
Device-to-device (D2D) communications can bring significant performance improvement by allowing direct communications between users. Most of previous work usually focuses on the optimization of throughput, energy efficiency, offloading and so on. However, the delay performance of D2D users is less considered. In this paper, we formulate a resource allocation problem to maximize the system throughput while guarantying the delay performance for each user. The resource allocation is dynamic due to the consideration of both channel state and the queue length information. The optimization problem is a mixed integer non-linear programming problem and the solution space is large. Then in order to solve the problem with low complexity, we introduce particle swarm optimization algorithm to the resource allocation scheme. Various simulation results show that the throughput of the scheme is close to the global optimum and the delay performance for each user is guaranteed.
