“…Figure shows the outage probability of the direct D2D communications and that for AF/DF relay‐aided scenarios (Equations and ) in different noise regimes. For low‐noise regime ( N 0 /2 = − 174 dBm/Hz), when the distance between TX/RX nodes of a D2D pair is less than 101 m, the direct mode has the lowest outage probability compared to relay‐aided strategies.…”

“…In this investigation, in addition to modeling the AF/DF relay‐aided scenarios similar to the direct D2D communications, we solve the nonanalytic integral by using Gauss‐Legendre‐based numerical method. It means that, unlike, there is no analytic or nonanalytic integral in the obtained expressions of this research work for the outage probability of relay‐aided scenarios. In order to have a fair comparison, we numerically analyze direct and relay‐aided scenarios in different SNR regimes.…”

“…In Reference , the coverage probability of both the CUs and the direct or relay‐assisted D2D users were analyzed. The exact formulas obtained in References , include some nonanalytic integrals which introduce high complexity for evaluating the outage probability of underlay relay‐aided D2D communications. In contrast, the obtained low‐complex closed‐form expressions are just valid for high‐enough SINRs.…”

Minimizing the outage probability and/or maximizing the throughput, optimally realize relay‐aided nonorthogonal in‐band (NO‐IB) device‐to‐device (D2D) communications. In this letter, we derive closed‐form expressions for the outage probability of NO‐IB amplify‐and‐forward (AF) and decode‐and‐forward (DF) relay‐aided D2D communications in Rayleigh fading channels. Numerical analyses show that the closed‐form formulas are in close agreement with the simulation results. Furthermore, we investigate the effect of signal‐to‐noise ratio and the distances between D2D pairs and relay nodes as well as cellular users. First results show that in the low‐noise regime, AF outperforms DF while they perform very close in the moderate noise level and DF outperforms AF in the high‐noise power. Second, we indicate that the relay‐aided AF/DF D2D communications is more reliable than the direct one when the TX/RX nodes of a D2D pair is distant approximately more than half of the cell radius.

In this paper, we investigate the strategy of transmission mode switching for device-to-device (D2D) communication in both single-cell scenario and multi-cell scenarios, which selects the transmission mode to guarantee the maximum ergodic achievable sum-rate among three transmission modes. We first introduce the basic operation principles of three communication transmission modes which are named as traditional cellular communication mode, direct D2D communication mode and two-way decode-and-forward (DF)-relayed D2D communication mode. Then we derive the corresponding expressions for the ergodic achievable sum-rates of each transmission mode, and get the crossing points of different transmission modes to attain maximum ergodic achievable sum-rate of the system. From the analytical results, we can see that the proper operating region of each transmission mode is related to different interference level and distance of the D2D users. Based on the analytical results, we obtain a reliable communication transmission mode switching strategy which guarantees the system to choose the mode with the maximum ergodic achievable sum-rate so as to improve the performance of D2D communication. Numerical results demonstrate that by applying mode switching, the ergodic achievable sum-rate of the system achieves a remarkable enhancement.
