“…In the overlay mode, CUEs and DUEs operate at two different frequency sub-bands. While the overlay technique works best in reducing interference, it results in the underutilization of the frequency resource [3,10]. Almost all previous works on D2D communications prioritize the underlay technique because it can accommodate more UEs on a given frequency band.…”

Device-to-device (D2D) communication-enabled cellular networks allow cellular devices to directly communicate with each other without any evolved NodeB (eNB). D2D communication aims to improve the spectral efficiency and increases the overall system capacity. For future mobile networks, intelligent radio resource allocation and power control schemes are required to accommodate the increasing number of cellular devices and their growing demand of data traffic. In this paper, a combined resource allocation and power control scheme for D2D communication is proposed. In the proposed scheme, D2D communication reuses the uplink (UL) resources of conventional cellular user equipments (CUEs); therefore, we have adopted single-carrier frequency division multiple access (SC-FDMA) as UL transmission scheme. The proposed scheme uses fractional frequency reuse (FFR)-based architecture to efficiently allocate the resources and mitigate the interference between CUEs and D2D user equipments (DUEs). In order to guarantee the user fairness, the proposed scheme uses the well-known proportional fair (PF) scheduling algorithm for resource allocation. We have also proposed an intelligent power control scheme which provides equal opportunity to both CUEs and DUEs to achieve a certain minimum signal-to-interference and noise ratio (SINR) value. The performance evaluation results show that the proposed scheme significantly improves the overall cell capacity and achieves low peak-to-average power ratio (PAPR).

In this paper, we study D2D (Device-to-Device) communication underlying LTE-Advanced uplink system. Since D2D communication reuses uplink resources with cellular communication in this scenario, it's hard for D2D users to avoid the interference from cellular users while cellular users are communication with eNB (evolved Node B). HARQ (Hybrid Automatic Repeat reQuest) is widely used in LTE-Advanced system in order to improve the accurate rate of cellular communication. Hence, we consider studying the integration of D2D with HARQ, so as to achieve the purpose of improving the throughput of D2D communication and the performance of overall system. Synchronous HARQ is considered to introduce into D2D communication procedures. What's more, this idea will be taken into system-level simulation. From the simulation results, we can see that the throughput of D2D communication gets a lot of gain and the performance of overall system is improved as well. In addition, Synchronous HARQ technique can significantly decrease the BLER (Block Error Rate) of D2D communication, especially for which in a bad channel condition.

Abstract-This paper studies possibility of using full-duplex (FD) radios in underlay device-to-device communication (D2D) in cellular networks. We consider a cellular system with one D2D pair and one cellular user. Cellular user is sharing the radio resources with D2D link which is equipped with full-duplex radios. The problem of sum-power minimization of cellular system and D2D link both in uplink and downlink period is considered. Considering the interference caused because of exploiting the same radio resources, for uplink period, we use fixed point iterations to solve the optimization problem to calculate transmit powers of users. To design the optimal receiver in the base station, linear minimum mean squared error method is used. In the downlink, to calculate optimal transmit precoder at base station and optimal D2D transmit powers, the optimization problem is formulated as a second order cone problem (SOCP) and solved using CVX in Matlab. Since the available full-duplex radios are not able to cancel the self-interference completely, residual of self-interference is considered in D2D receivers. Performance of the full-duplex D2D with different amounts of self-interference cancelation is compared to that of half-duplex D2D. Results show that full-duplex radios with 110 dB self-interferece cancelation can provide double the throughput for D2D compared to halfduplex radios.
