“…Zhou et al [67] considered the wirelessly powered WP-NOMA-assisted BC for an IoT network in which one power beacon (PB), many IoT devices, and one information receiver (IR) are included. IoT devices harvest the energy from the PB signal and backscatter that signal to transfer the information from devices to IR.…”

“…Departing from the earlier research conducted for uplinkbased works in [67] and [70], Khan et al [79] considered downlink PD-NOMA enabled AmBC with imperfect SIC decoding for future 6G technologies. The main objective of the proposed scheme is to enhance the sum rate of the system.…”

“…A closed-form solution is formulated using an iterative algorithm, validating the results by comparing them with other power domain NOMA schemes. In contradistinction to the preceding works for uplink and downlink NOMA considering perfect CSI in [67], [70], and [79], Khan et al [80] considered statistical CSI for NOMA-enabled BC for IoT networks and proposed the optimum solution to enhance the system's sum capacity. The authors jointly optimized the IoT device's transmission power and the BD's RC and derived it as a convex problem.…”

<p>This survey aims to bridge the gap by exploring NOMA-BC within B5G and 6G networks. We delve into its technical aspects, performance optimization techniques, and real-world applications to enhance understanding and knowledge. First, we cover topics such as enhancing EE, maximizing the sum rates, ensuring security, and optimizing resource allocation. Our primary goal is to provide researchers and practitioners with valuable insights that enable them to grasp the capabilities and benefits of NOMA-BC. To achieve this, we comprehensively analyze various schemes' performance by presenting detailed summary tables. These analyses cover a range of scenarios, methods, and objectives, focusing on emerging B5G technologies such as reconfigurable intelligent surfaces (RIS), visible light communication (VLC), and unmanned aerial vehicle (UAV) communication. By examining NOMA-BC's effectiveness within these contexts, we aim to provide a holistic view of its potential and applicability in diverse technological domains. Moreover, our survey identifies and discusses open research challenges and proposes future directions to guide researchers toward unexplored areas and facilitate advancements in NOMA-BC.</p>

“…In recent times, a handful of literature appeared that integrated backscatter communication with either NOMA (e.g. [5], [7], [8]), TDMA [3], [9], or a hybrid NOMA-plus-TDMA [6], [10]. However, to the best of the authors' knowledge, studying and comparing the conventional NOMA and TDMA and the hybrid NOMA-plus-TDMA techniques while judiciously exploiting the complementary nature of EH devices and the BTs for a cooperative-WPCN is still unexplored.…”

This work explores a cooperative wireless powered communication network (WPCN) aided by multiple backscatter devices. In this work, for the envisioned hybrid user scenario, we maximize the weighted sum throughput under a joint set of constraints in the time allocation parameter, a set of reflection coefficients of backscatter devices, and the constraints for meeting the successive interference cancellation threshold requirements. Henceforth, we investigate various sub-problems and propose our solution to the formulated non-convex optimization problem. Finally, using extensive numerical simulations, we observe that the hybrid NOMA-plus-TDMA scheme outperforms a few benchmark and existing conventional schemes for our considered system model.

“…Few literatures have appeared in recent times that integrate either backscatter communication and NOMA [4]- [8] or RF-EH and NOMA [9], [10], with NOMA as their multiple access scheme. However, many of these works do not study the effect of the combination of NOMA and TDMA on the performance in their respective system models.…”
