“…Under the overlay cellular spectrum-sharing scheme, the D2D devices can only access the cellular simultaneously forward the cellular uesrs' data and convey its own data [24,25]. As we know, NOMA technology has not been considered in overlay D2D cooperation communications in [13,14,[19][20][21]. Considering the combination of NOMA technology and cooperative overlay D2D communication, the transmission power allocated by the DT for the cooperative communication and the D2D transmission may directly affect the transmission rate and the energy consumption of the D2D devices.…”

This paper proposes a reciprocal-selection-based ‘Win–Win’ overlay spectrum-sharing scheme for device-to-Device-enabled cellular networks to address the resource sharing between Device-to-Device devices and the cellular users by using an overlay approach. Based on the proposed scheme, the cell edge users intend to lease part of its spectrum resource to Device-to-Device transmission pairs. However, the Device-to-Device users have to provide the cooperative transmission assistance for the cell edge users in order to improve the Quality of Service of the uplink transmission from the cell edge users to the base station. Compared to the underlay spectrum-sharing scheme, overlay spectrum-sharing scheme may reduce spectrum efficiency. Hence, Non-Orthogonal Multiple Access technology is invoked at the Device-to-Device transmitter in order to improve the spectrum efficiency. The Stackelberg game is exploited to model the behaviours of the cell edge users and Device-to-Device devices. Moreover, based on matching theory, the cell edge users and Device-to-Device pairs form one-to-one matching and the stability of matching is analysed. The simulation results show that the proposed reciprocal-selection-based ‘Win–Win’ overlay spectrum-sharing scheme is capable of providing considerable rate improvements for both EUs and D2D pairs and reducing transmit power dissipated by the D2D transmitter to forward data for the EU compared with the existing methods.

“…Simulation results show that the proposed algorithm outperformed the single one-channel-based algorithm. In [15], the authors propose a mode selection algorithm which combines the advantages of both underlay mode and overlay mode. In the algorithm, some devices can switch to overlay mode to improve the spectrum utility.…”

Device-to-Device (D2D) communications can provide proximity based services in the future 5G cellular networks. It allows short range communication in a limited area with the advantages of power saving, high data rate and traffic offloading. However, D2D communications may reuse the licensed channels with cellular communications and potentially result in critical interferences to nearby devices. To control the interference and improve network throughput in overlaid D2D cellular networks, a novel channel assignment approach is proposed in this paper. First, we characterize the performance of devices by using Poisson point process model. Then, we convert the throughput maximization problem into an optimal spectrum allocation problem with signal to interference plus noise ratio constraints and solve it, i.e., assigning appropriate fractions of channels to cellular communications and D2D communications. In order to mitigate the interferences between D2D devices, a cluster-based multi-channel assignment algorithm is proposed. The algorithm first cluster D2D communications into clusters to reduce the problem scale. After that, a multi-channel assignment algorithm is proposed to mitigate critical interferences among nearby devices for each D2D cluster individually. The simulation analysis conforms that the proposed algorithm can greatly increase system throughput.

Full-duplex communications emerged as an alternative to improve throughput and spectrum usage on the forthcoming fifth-generation (5G) mobile networks. However, the existing medium access control schemes for full-duplex lack mechanisms designed to enhance spectrum usage. In this context, this work proposes FDDS-MAC, which is a full-duplex communication scheme tailored to improve spectrum usage. FDDS-MAC introduces a decision phase where the receiver with a higher probability of having data back to the sender is prioritized in the sender's packet queue. Thus, FDDS-MAC is able to perform packet rescheduling to boost throughput and spectrum usage. Numerical results show that FDDS-MAC has a positive impact over full-duplex communications, achieving throughput up to 40% higher than a state-of-art full-duplex scheme.
