Device-to-device (D2D) communication is a promising future wireless network technology that establishes a direct link between the devices in close vicinity. Along with the improved end-to-end latency and network rate, it also enhances the spectral and power efficiency. Most of the previous works on interference management and resource allocation have considered half-duplex (HD) D2D systems and have assumed that D2D pairs cannot access more than a single channel at a time and a cellular channel is assigned to at most one D2D pair. In this article, we investigate multiple-pair-multiple-channel (MPMC) allocation scenario over multiple-input-multiple-output-based full-duplex D2D networks.The idea is to maximize the aggregate sum data rate of the D2D network by optimal allocation of the resources and maintaining a desired threshold rate for the cellular users. The cross-tier interferences are intelligently handled by appropriate channel allocation and the co-tier interferences by proper power allocation.The efficacy of the proposed MPMC algorithm has been evaluated through rigorous simulations, and an appreciably better network rate has been found as compared with the single-pair-single-channel-based allocation. Moreover, by allowing more users to communicate in tandem, with enhanced average rate, the results also ensure a better opportunity of higher utilization of the scarce licensed cellular spectrum. The presented algorithm has also been compared with random and uniform based allocations and further analyzed in HD-MPMC communications.

“…Majority of the work related to resource allocation for D2D is dedicated to the centralized approaches in the literature . Overall sum rate of D2D and CU is maximized by proposing a greedy channel assignment for downlink and uplink D2D in Zulhasnine et al while considering the quality of service (QoS) of each user.…”

“…Apart from these, multiple channels are assigned to D2D pair in previous studies but a channel is not reused among multiple D2D pairs. An optimal joint channel and power optimization for downlink D2D is proposed in previous studies to maximize D2D sum rate while preserving the performance of CU.…”

“…An optimal joint channel and power optimization for downlink D2D is proposed in previous studies to maximize D2D sum rate while preserving the performance of CU. A QoS aware resource allocation is done in Gour and Tyagi where a D2D is assigned multiple CU's channel; however, the maximum number of channel to each D2D is constrained. The authors in a previous work do not optimize the CU power as equal power is assumed for each CU.…”

Power allocation, mode, and channel selection for relay based D2D is studied in Hoang et al to maximize system rate satisfying minimum rate requirement of D2D and CU links.The authors of another study demonstrated the admission control, power, and channel allocation to maximize D2D throughput in uplink as well as downlink phase.…”

Device-to-device (D2D) communication is a viable solution proposed by the Third Generation Partnership Project (3GPP) to handle the enormous number of devices and expected data explosion in 5G. It is competent in enhancing the system performances such as increased data rate, reduced delay, and less power consumption while maintaining a low load on the base station (BS). In this paper, channel assignment and power control scheme is proposed for underlay D2D system where one cellular channel is allowed to be shared among multiple D2D pairs. This will lead to enhanced spectral efficiency on the cost of additional interferences introduced among the D2D and cellular users (CUs). Our aim is to maximize the D2D throughput without degrading the performance of existing CU that is sharing the channel with D2D. This is achieved by maintaining a threshold signal-to-interference-plus-noise ratio (SINR) for each CU. A centralized channel assignment algorithm based on the well-known two-sided preference Gale-Shapley algorithm is proposed, named as RAbaGS-HR. Further, suboptimal distributed power control (DPC) algorithms are proposed for both uplink and downlink D2D. The novelty of the work lies in the facts that a channel is shared among multiple D2D users and the optimal power is calculated for all the users sharing the same channel under the full consideration of all kinds of interferences unlike most of the existing work that either assumed the fixed CU power or ignored the interferences among the D2D users. Numerical results show the efficacy of the proposed algorithms in terms of significant gain in throughput with a very low computational cost. In addition to this, the energy efficiency (EE) is also analyzed for different D2D user density, with respect to average circuit power consumption and D2D maximum transmit power.
