“…Similarly, an approximate analytical expression for the uplink achievable rate of an mMIMO system with finite-precision ADCs and maximal ratio combining (MRC) receivers has been studied in [27]. The authors of [28] have considered the joint power control and resource allocation for a device-to-device (D2D) underlay cellular system with a multi-antenna BS employing ADCs with different resolutions. Similarly, the uplink achievable SE of multiuser distributed mMIMO with mixed-ADC receivers has been studied in [29].…”

In this paper, we propose a scheme for the joint optimization of the user transmit power and the antenna selection at the access points (AP)s of a user-centric cell-free massive multiple-inputmultiple-output (UC CF-mMIMO) system. We derive an approximate expression for the achievable uplink rate of the users in a UC CF-mMIMO system in the presence of a mixed analog-to-digital converter (ADC) resolution profile at the APs. Using the derived approximation, we propose to maximize the uplink sum rate of UC CF-mMIMO systems subject to energy constraints at the APs. An alternatingoptimization solution is proposed using binary particle swarm optimization (BPSO) and successive convex approximation (SCA). We also study the impact of various system parameters on the performance of the system.

“…In [17], a clustering method is proposed in out‐of‐band D2D to enhance the spectrum reuse, while in [18], the base station selects the relay that minimizes the energy consumption. Paper [19] also considers a centralized joint power control and resource allocation. The authors propose a multi‐antenna base station employing ADCs with different resolutions.…”

The expansion of smart devices and throughput requirements have triggered the integration of multi-hop Device to Device (D2D) underlay the fifth generation (5G) network. This new paradigm has extended the coverage area and enabled ultra-low latency and cost-per-bit communications. While the previous 3GPP releases address only the coverage problem via two-hop D2D, this paper focuses on multi-hop D2D defined in 3GPP release 15 and beyond. It proposes a distributed relay selection and resource allocation algorithm based on a mixed strategy game and a novel amplify and forward factor. The proposed schema maximizes the joint spectral and energy efficiency. Besides, it determines the optimal amount of data and energy transferred by each device. The efficiency of this approach against other state-of-the-art solutions is evaluated and verified through computer simulations.
