“…Moreover, the outage probability expressions for CU-BS and D2D pairs are also derived. The scheme proposed in [18] is shown to outperform the conventional C-D2D system in terms of outage probability. However, the analysis is limited to HD transmission mode (TM) only, and the performance comparison with FD TM is not investigated.…”

“…Performance analysis of C-D2D communications system with HD relay has been widely studied in the literature [15]- [17]. For instance, an orthogonal frequency division multiple access (OFDMA) based HD C-D2D system with best relay selection is proposed in [18], wherein out of M available D2D transmitters, only the best in-coverage user equipment (UE) is selected as a relay, which transmits the data from the source node to the destination node. Moreover, the outage probability expressions for CU-BS and D2D pairs are also derived.…”

“…The remaining L − Z subcarriers can be shared among M DTs for D2D communications. For fair subcarriers allocation among M D2D users, a "Round-robin process with priority cube for subcarriers sharing between DTs" algorithm is used as defined in [18]. The algorithm facilitates simultaneous transmission opportunities to M D2D users while satisfying the cellular outage probability constraint.…”

Full-duplex (FD) transmissions have emerged as a spectrally efficient technology with the evolution of enhanced self-interference (SI) suppression techniques. However, the FD transmission mode (TM) may not consistently outperform the half-duplex (HD) TM due to the residual SI. In contrast, an adaptive FD/HD transmission scheme utilizes the advantages of both FD and HD TM. This paper proposes an adaptive FD/HD transmission scheme for a cooperative device-to-device (C-D2D) communications system wherein cellular uplink data is relayed through a D2D transmitter (DT). Additionally, a joint DT and TM selection algorithm is introduced to identify the best relay and favorable TM for the multiuser C-D2D system. Further, a probabilistic mathematical framework is developed to evaluate the proposed adaptive FD/HD transmission scheme. The analytical expressions of D2D and cellular outage probability for each TM (FD/HD) have been derived. Results show that FD TM performs better than HD TM when a maximum of two D2D users mapped to a cellular user. However, a trade-off between FD and HD TM is observed for a large number of D2D users. Specifically, when the cellular outage constraint is low, HD TM performs better than FD TM, whereas FD TM outperforms HD TM for high cellular outage constraint.

“…The critical observation from (28) and (29) is that the upper bound and the lower bound of the price do not depend on any values v mn of DP n and only depends on the final matching and the value vectors of other D2D pairs. This fact implies the robustness of the DMA, which is stated in Theorem 4.…”

We consider a cooperative device-to-device (D2D) communication system, where the D2D transmitters (DTs) act as relays to assist cellular users (CUs) in exchange for the opportunities to use the licensed spectrum. To reduce the overhead, we propose a novel two-timescale resource allocation scheme, in which the pairing between CUs and D2D pairs is decided at a long timescale and time allocation factor for CU and D2D pair is determined at a short timescale. Specifically, to characterize the long-term payoff of each potential CU-D2D pair, we investigate the optimal cooperation policy to decide the time allocation factor based on the instantaneous channel state information (CSI). We prove that the optimal policy is a threshold policy. Since CUs and D2D pairs are self-interested, they are paired only when they agree to cooperate mutually. Therefore, to study the behaviors of CUs and D2D pairs, we formulate the pairing problem as a matching game, based on the long-term payoff of each possible pairing. Furthermore, unlike most previous matching model in D2D networks, we allow transfer between CUs and D2D pairs to improve the performance. Besides, we propose an algorithm, which converges to an ǫ-stable matching.

“…However, communication distance limits the application scope of D2D communication. Adding relay nodes in D2D communication can expand its application scope and improve the success rate of connection establishment [2][3][4]. Due to the introduction of relay nodes, D2D communication changes from one-hop communication to multi-hop communication, but the reliability of the relay node directly affects the success rate of communication connection, in order to enhance the communication security and ensure that the communication process can be established normally, some researchers quantify social relationship between people to find a relay node which has a stronger willingness to participate in D2D relay communication.…”

The emergence of 5G has promoted the rapid development of the Internet of Things(IOT), the dramatic increasing of mobile equipment has led to the increasing shortage of spectrum resources, D2D(Device-to-Device) communication technology is widely concerned for its ability to improve the utilization of spectrum resources. In order to expand the communication scope, relay nodes are introduced into D2D communications, as the third party of D2D relay communication, the quality of relay nodes directly affects the quality of communication process. In order to make more users willing to participate in relay communication, social relationship is introduced into D2D relay communication, However, as an explicit relationship between people, the function of social relationship in D2D communication is limited by the mobility of users and the variability of communication scenarios. In order to find a more reliable relay node and upgrade the connection success rate of D2D relay communication, implicit social relationship between the users need to be mined. Aiming at that, user trust degree (UTD) is established in this paper. By combining the explicit relationship which is called the social connectivity degree with the implicit social relationship called the interest similarity degree, and considering the user’s movement, a relay selection algorithm is presented to help sender find a relay node with a deeper user trust, which can increase the user’s willingness to participate in D2D relay communication and upgrade the success rate of communication connection, so this algorithm can ensure the security of the relay node and can improve the throughput performance. Simulation results show that this algorithm can increase the success rate of connection, improve the overall throughput of the system and improve the user's communication experience.
