Multichannel allocation for full‐duplex underlay device‐to‐device communication

Abstract

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.

Outage probability minimization based power control and channel allocation in underlay D2D‐NOMA for IoT networks

“…Majority of the aforementioned works [7][8][9][10][11][12][13][14][15][16][17][18][19][20][21] study resource allocation problem by maximizing either sum-rate or signal-to-interference-plus-noise ratio (SINR), but do not consider optimization of system OP, which holds a significant importance, 22,23 especially in the context of power control problem in NOMA transmissions. OP is a very fundamental performance measure which is suitable for analyzing low mobility D2D communication with slowly varying fading channels where the instantaneous signal to noise ratio (SNR) is assumed to be constant for a large number of symbols.…”

“…Authors in Reference 7 considered channel allocation (CA) problem in an orthogonal multiple access (OMA)‐based D2D network. In Reference 8, a joint power allocation (PA) and uplink CA problem was investigated with maximization of the network rate while maintaining quality of service (QoS) for the CUs in the form of a guaranteed threshold rate. Authors in Reference 9 considered underlay D2D communication in mm‐Wave band and proposed a power control scheme to maximize the energy efficiency.…”

Interference‐aware feedback based iterative Hungarian approach to allocate multiple channels to multiple D2D pairs to maximize underlay D2D network capacity

“…Therefore, the multiple‐pair multiple‐channel (MPMC) scheme has recently started gaining attention 8 as it increases both connection‐density as well as the per‐pair data rate. Additionally, as a D2D pair utilizes more than one channel, the connection is more resilient.…”

Power control scheme for device‐to‐device communication using uplink channel in 5G mm‐Wave network

“…It efficiently optimizes the connectivity with lower end‐to‐end delay. The authors in Reference 26, proposes an optimized power allocation scheme to maximize the overall throughput of D2D users by using multiple‐pair‐multiple‐channel (MPMC) algorithm. However, there is a dearth of papers dealing with rigid pathloss model for implementation of D2D communication in mm‐Wave network.…”
