“…In [26], the authors have proposed novel closed-form expressions for outage probability under both overlay mode and underlay mode, where the Nakagami-m fading channel is considered. Furthermore, the system sum-rate maximization problems have been extensively considered in [27]- [31]. The RIS-aided scenario with one uplink cellular link and multiple D2D links has been utilized to jointly optimize the transmission power of all links as well as the discrete phase shifts of the surface [27], while [28] has considered multiple cellular users and added the resource reuse indicators for optimization.…”

The cellular network coexisting with device-to-device (D2D) communications has been studied extensively. Reconfigurable intelligent surface (RIS) and non-orthogonal multiple access (NOMA) are promising technologies for the evolution of 5G, 6G and beyond. Besides, sparse code multiple access (SCMA) is considered suitable for next-generation wireless network in code-domain NOMA. In this paper, we consider the RIS-aided uplink SCMA cellular network simultaneously with D2D users. We formulate the optimization problem which aims to maximize the cellular sum-rate by jointly designing D2D users' resource block (RB) association, the transmitted power for both cellular users and D2D users, and the phase shifts at the RIS. The power limitation and users' communication requirements are considered. The problem is non-convex, and it is challenging to solve it directly. To handle this optimization problem, we propose an efficient iterative algorithm based on block coordinate descent (BCD) method. The original problem is decoupled into three subproblems to solve separately. Simulation results demonstrate that the proposed scheme can significantly improve the sum-rate performance over various schemes.INDEX TERMS Reconfigurable intelligent surface (RIS), non-orthogonal multiple access (NOMA), resource allocation, device-to-device (D2D), sparse code multiple access (SCMA)

“…Besides, the authors in [30] have presented a D2D-underlaid cellular system, where the multiple RISs are deployed at the cell boundary to improve propagation. RIS has also been introduced to joint processing coordinated multipoint (JP-CoMP) cellular networks with underlaying D2D communications to mitigate the interference [31].…”

“…IRS-aided D2D communication: IRS is expected to assist D2D communication by improving the communication links between devices by providing a robust virtual link in case of blockage. However, when offloading using D2D devices latency [ 112 , 113 ], sum-rate maximization [ 114 ] and secrecy-rate maximization [ 115 ] will be key issues. Developing and designing D2D algorithms to solve these abovementioned issues will be an important area of research.…”

The existing sub-6 GHz band is insufficient to support the bandwidth requirement of emerging data-rate-hungry applications and Internet of Things devices, requiring ultrareliable low latency communication (URLLC), thus making the migration to millimeter-wave (mmWave) bands inevitable. A notable disadvantage of a mmWave band is the significant losses suffered at higher frequencies that may not be overcome by novel optimization algorithms at the transmitter and receiver and thus result in a performance degradation. To address this, Intelligent Reflecting Surface (IRS) is a new technology capable of transforming the wireless channel from a highly probabilistic to a highly deterministic channel and as a result, overcome the significant losses experienced in the mmWave band. This paper aims to survey the design and applications of an IRS, a 2-dimensional (2D) passive metasurface with the ability to control the wireless propagation channel and thus achieve better spectral efficiency (SE) and energy efficiency (EE) to aid the fifth and beyond generation to deliver the required data rate to support current and emerging technologies. It is imperative that the future wireless technology evolves toward an intelligent software paradigm, and the IRS is expected to be a key enabler in achieving this task. This work provides a detailed survey of the IRS technology, limitations in the current research, and the related research opportunities and possible solutions.

“…For instance, the authors in [17] considered deploying IRS in the integrated data and energy network coexisting with D2D communication to maximize the minimum throughput of the information-demanded users. In [18], a resource allocation design for the IRS-aided joint processing coordinated multipoint (JP-CoMP) system with underlaying D2D network was investigated. The authors in [19] studied an IRS-aided D2D communication system over Rician fading channels with the consideration of practical hardware impairments at both the terminals and IRSs.…”

Intelligent reflecting surface (IRS) and device-todevice (D2D) communication are two promising technologies for improving transmission reliability between transceivers in communication systems. In this paper, we consider the design of reliable communication between the access point (AP) and actuators for a downlink multiuser multiple-input single-output (MISO) system in the industrial IoT (IIoT) scenario. We propose a two-stage protocol combining IRS with D2D communication so that all actuators can successfully receive the message from AP within a given delay. The superiority of the protocol is that the communication reliability between AP and actuators is doubly augmented by the IRS-aided first-stage transmission and the second-stage D2D transmission. A joint optimization problem of active and passive beamforming is formulated, which aims to maximize the number of actuators with successful decoding. We study the joint beamforming problem for cases where the channel state information (CSI) is perfect and imperfect. For each case, we develop efficient algorithms that include convergence and complexity analysis. Simulation results demonstrate the necessity and role of IRS with a well-optimized reflection matrix, and the D2D network in promoting reliable communication. Moreover, the proposed protocol can enable reliable communication even in the presence of stringent latency requirements and CSI estimation errors.Index Terms-D2D communication, industrial Internet of things (IIoT), intelligent reflecting surface (IRS), robust beamforming, URLLC I.
