“…Finally, the outages decode the metric of ( 7) and extract the image code. This indicates that the proposed diversity approach is equivalent to the maximal ratio combining (MRC) diversity technique [23], which will be verified in section IV. Since the MRC diversity method guarantees the optimal performance [23], the presented cell diversity significantly improves reliability performance.…”

This paper addresses novel wireless emergency alerts based on image code and cell clustering in 5G cellular systems. Most cellular systems offer a cell broadcast technique for emergency alert delivery. The cell broadcast method simultaneously delivers text-based messages to the users in specific cells, which encompass emergency areas. For the simultaneous delivery, the cell broadcast approach relies on a broadcast mechanism, which is called cell broadcast service in the 3GPP standard. However, the cell broadcast service exhibits high latency under poor channel conditions. Moreover, the cell broadcast service may be useless for illiterate persons or foreigners since the service just offers text-based messages. For more rapid and reliable delivery, we propose a novel cell broadcast method for 5G wireless emergency alerts. The new technique enables image-based emergency alerts. For the image-based alerts, the presented approach embeds an image code in the alert message. For the image-code embedment, the method effectively exploits the feature of the message structure. The novel approach also offers a cell clustering technique. 5G mobile terminals can rely on the cell clustering in order to achieve a cell diversity, which considerably enhances latency and reliability performance. The experimental results exhibit that the proposed alert method is superior to the conventional technique in terms of latency and reliability.

“…The demand for mobile data access has been growing rapidly in the past few years, driven by a large number of new subscribers, high data rate applications, and emerging Internet of Things (IoT) applications, which require massive connectivity. Therefore, the limited capacity problem became prominent [1], [2]. According to Ericsson mobility report [3], mobile network data traffic grew 44% between 2020 and 2021, and reached 72 Exabyte per month generated by about 8 billion subscribers.…”

In reconfigurable intelligent surface (RIS)-assisted communications, the signal-to-noise ratio (SNR) is improved by optimizing the reflecting elements' phases to make the reflected signals add coherently at the receiver. Nevertheless, the RIS cannot control the phase of the direct link if it exists. Although the RIS phase can still be controlled such that the direct and reflected signals add coherently, the SNR gain might be hindered. Therefore, this paper considers the performance analysis of such scenarios where a novel analytical framework is developed to evaluate the SNR, outage probability, and bit error rate (BER). To capture a broad range of fading conditions, the channels are modeled as independent but not identically distributed generalized κ-µ shadowed fading channels. The Laplace transform is used to derive an accurate approximation of the probability density function (PDF) and cumulative distribution function (CDF) of the instantaneous fading, which are used to derive the PDF and CDF of the instantaneous SNR. The paper also considers deriving the asymptotic PDF, CDF, moment generating function (MGF) of the SNR, as well as the outage probability and BER. The obtained results show that a strong direct link may limit the gain obtained using the RIS.
