In view of noteworthy communications performance improvements for future B5G/6G
ubiquitous networks (such as cognitive Internet of Things (IoT) network, UAV …

User cooperation although improves performance of wireless systems, it requires incentives
for the potential cooperating nodes to spend their energy acting as relays. Moreover, these …

In this article, in order to substantially improve outage probability (OP), we propose a
generalized optimal relays subsets selection algorithm in a cloud-based 6G large-scale …

Sidelink relay technique is an effective technique for coverage enhancement and data rate
improvement, which has recently achieved success in diversified wireless applications. The …

Relay selection is a simple technique that achieves spatial diversity in cooperative relay
networks. Generally, relay selection algorithms require channel state information (CSI) …

Best relay selection (BRS) is crucial in enhancing the performance of cooperative networks.
In contrast to most previous works, where the guidelines for BRS are limited to Gaussian …

Pilot contamination poses a critical challenge for channel estimation in dense cell-free (CF)
