Title
Adaptive Yielding Scheme for Link Scheduling in OFDM-Based Synchronous D2D Communication System
Abstract
As compared to asynchronous contention-based random access, synchronous & distributed link scheduling for OFDM system turns to be a viable solution to improve the system throughput for device-to-device (D2D) communication. In particular, a spatial spectral efficiency can be improved by scheduling the concurrent D2D links as many as the individual signal-to-interference ratio (SIR) requirement is satisfied. In this paper, we propose an adaptive yielding mechanism that can further improve the spatial spectral efficiency by allowing for more concurrent D2D links whenever more interference can be accepted, e.g., when the instantaneous bandwidth efficiency requirement is less than the current link capacity. Even if the system throughput varies with the link density, it has been shown that the average system throughput can be significantly improved by the proposed yielding mechanism.
