This mechanism may not always be adequate for the complex nature of fifth generation and beyond (B5G) networks, and may lead to load biasing. Additional parameters, such as the load on the neighboring cells, the needs of the user equipment (UE), and the UE mobility should be considered as well. The realization that relying solely on the signal strength and quality for UA may violate load balancing has been recognized for a long time. However, the approach taken was to balance the load by a network-dependent mechanism. Yet, the UA mechanism remains based on the best-received signal. The underlying assumption that all the users have the same needs remains. Load-aware UA was considered only upon mobility-driven handover to small cells. This study suggests a UE-based threshold scheme for load-aware UA that is suitable for B5G networks. Since the optimal UA problem is known to be NP-hard, we suggest a heuristic mechanism, that is sufficiently simple and reliable to be implemented in practice, yet sufficiently efficient to significantly outperform the existing UA mechanism.

In this survey, we present a review of existing literature that aims to alleviate the scalability and reliability issues in quantum computers. In particular, we discuss how existing research leads to two main solutions: for advancing scalability, a distributed quantum computing (DQC) paradigm will be the primary direction instead of the general centralized quantum computing (CQC), whereas for attaining reliability, a fault-tolerant quantum computation (FTQC) approach would need to be leveraged instead of the existing noisy intermediate-scale quantum computers (NISQ). Combining both solutions, we highlight the essentiality of fault-tolerant distributed quantum computation (FT-DQC) and present related progress in the field.
