Proximity user detection based resource allocation scheme for device-to-device communication

Abstract

In this paper, we propose a resource allocation schemes, called proximity user detection-based resource allocation (PUDRA), or advanced proximity user detection-based resource allocation (APUDRA) in an LTE-Advanced device-to-device (D2D) network. In the proposed schemes, in order to reduce the interference between macro user equipment (mUEs) and D2D links or between D2D links, D2D link shall use a frequency bandwidth that the neighboring mUEs or D2D links do not use. We analyzed and compared the two schemes and the random resource allocation scheme in terms of the system throughput for downlink and outage probability according to the number of D2D receivers (D2DRs). Simulation results show that the APUDRA scheme has better performance than the PUDRA and random resource allocation scheme performance in terms of the system throughput and outage probability for mUEs and D2DRs. , where he is an associate professor.
