“…Ai et al [6] performed some measurements and simulations on indoor mmWave massive multiple-input multipleoutput (MIMO) channel at a band in 26 GHz. Shariat et al [28] presented some important findings in designing radio resource management (RRM) functionalities of mmWave in conjunction with heterogeneous network in both backhaul and access links. Rebato et al [29] proposed an effective novel hybrid spectrum access scheme consisted of the exclusive low frequency carrier and the pooled high frequency carrier for mmWave networks.…”

Heterogeneous cellular networks (HCNs) with millimeter wave (mmWave) communications included are emerging as a promising candidate for the fifth generation mobile network. With highly directional antenna arrays, mmWave links are able to provide several-Gbps transmission rate. However, mmWave links are easily blocked without line of sight. On the other hand, D2D communications have been proposed to support many content based applications, and need to share resources with users in HCNs to improve spectral reuse and enhance system capacity. Consequently, an efficient resource allocation scheme for D2D pairs among both mmWave and the cellular carrier band is needed. In this paper, we first formulate the problem of the resource allocation among mmWave and the cellular band for multiple D2D pairs from the view point of game theory. Then, with the characteristics of cellular and mmWave communications considered, we propose a coalition formation game to maximize the system sum rate in statistical average sense. We also theoretically prove that our proposed game converges to a Nash-stable equilibrium and further reaches the nearoptimal solution with fast convergence rate. Through extensive simulations under various system parameters, we demonstrate the superior performance of our scheme in terms of the system sum rate compared with several other practical schemes.

“…In [21], [22], authors propose an outage probability based on amplify-and-forward (AF) cooperative communication to address power allocation minimization problem and attain a closed-form outage probability expression. A distributed relay selection along with power allocation for an OFDMA mmWave network is studied in [9]. A relay selection for N number of non-Line-of-sight (NLOS) links is studied in [23] with an objective to maximize the total throughput of the NLOS links.…”

Joint Relay-Spectrum Selection in Hybrid Millimeter-Microwave Cooperative (HMMC) Network Using Fall-Back Approach

The microwave (µWave) spectrum or low-frequency spectrum has become overcrowded due to the ever-increasing demand in bandwidth-intensive applications, such as video streaming and gaming. Owing to the fact that the spectral efficiency of µWave links is approaching its fundamental limits, there is a growing consensus in both industry and academia that millimeter wave (mmWave) will play an important role in increasing data rate and scarcity of spectrum. To redress the predicament and to ensure adequate availability of bandwidth, increasing attentions have been paid to the use of mmWave spectrum for future broadband wireless networks. The mmWave spectrum offers wider bandwidth compared to the µWave spectrum and a promising solution to overcome the scarcity of spectrum while providing gigabits per second (Gb/s) of data rates. To fully exploit the high potential rates of mmWave in mobile networks, a number of technical problems must be addressed. The mmWave signal transmission suffers from the issues of blockage and deafness. The former challenge is characterized by the loss of Quality of Service (QoS) in non-line-of-sight (NLOS) conditions, while the latter is characterized by the misalignment between the main lobe of transmitter and the receiver beam. Two strategies can be adopted to deal with the issues:1) relaying, use of another path with the help of relay(s) providing line-of-sight (LOS) link(s) and b) fall back, in the case of service interruption, switch back to the µWave spectrum-based transmission switching between mmWave and µWave frequency bands can support higher rates and QoS requirements. However, a tradeoff exists in employing any of the aforementioned strategies. In this paper, we study the joint spectrum allocation and relay selection problem to maximize the weighted sum rate relay selection (using resource block and time slot) along with a fallback approach for spectrum allocation in an HMMC network. A fallback approach is introduced to enable the hybrid transmission of µWave and mmWave, and an iterative bipartite relay-spectrum selection algorithm is proposed to solve the problem. The performance evaluation results show that the proposed fallback approach outperforms the conventional µWave or mmWave transmission schemes in terms of data rate, transmit power, and the number of users.
