This letter proposes a new mode selection scheme to improve the overall packet rates for device-to-device (D2D) communications systems in the bursty traffic model. We consider three types of D2D modes, i.e., dedicated mode, cellular mode, and reuse mode. In the full-buffer traffic model, if all the uplink (UL) channels are occupied by cellular users, the dedicated and cellular modes are not available...
This paper proposes a rate allocation scheme for throughput maximization considering rate fairness in wireless relay systems. The throughput maximization problem is formulated to two link data rate balancing problems: global balancing and local balancing. And the rate fairness is converted to data rate balancing of each destinations. Based on this, we construct a feasible rate region (FRR) which is...
