To alleviate the impact of outages caused by dynamic blockage of propagation paths in millimeter wave (mmWave) systems, 3GPP has proposed multi-connectivity operation, where user equipment (UE) maintains simultaneous links to both sub-6 GHz and mmWave BSs. We address one of the most challenging prospective deployments - multi-lane street deployment with intra- and inter-RAT multi-connectivity. By utilizing the mixture of analytical and simulation tools, we first characterize the outage characteristics at mmWave layer. These characteristics further serve as an input to the queuing model characterizing service performance of sub-6 GHz BS serving sub-6 GHz and temporarily offloaded mmWave sessions and implementing traffic protection strategies. Our numerical results show that the use of inter-RAT multi-connectivity to offload mmWave sessions decreases sub-6 GHz session rate multiple times while utilizing multi-connectivity at the mmWave layer allows to partially compensate it. Traffic 'jam' road conditions affect the sub-6 GHz session rate reducing it by approximately 20% compared to 'normal' road traffic conditions. Furthermore, reserving shares of resources to sub-6 GHz and mmWave traffic favors 'heavy-weight' mmWave sessions. On the other hand, individual session resource allocation leads to fair performance. However, this option induces the trade-off between the attained rate and the session drop probability.

Unmanned aerial vehicle (UAV)-assisted reconfigurable intelligent surface (RIS) systems can enhance physical layer security through joint mobility and propagation control. However, most existing designs assume the availability of the eavesdropper's channel state information (CSI), which is unrealistic in passive eavesdropping scenarios. In this paper, secure UAV-RIS downlink communication is studied under bounded eavesdropper location uncertainty, ...

In a wireless communication system, signals sent into the channel interact with the environment in a very complex way. Thereby transmitted signals may be subject to many forms of degradation among which there are causes of multipath propagation: • Reflections due to obstacles with the size greater than a wavelength; • Refractions due to the ...

We consider unsourced random access with MIMO receiver – a crucial communication scenario for future 5G/6G wireless networks. We perform a projection-based decoder analysis and derive energy efficiency achievability bounds when channel state information is unknown at transmitters and the receiver (no-CSI scenario). A comparison to the maximum-likelihood (ML) achievability bounds by Gao et al. ...

We investigate the fundamental limits of the unsourced random access over the binary-input Gaussian channel. By fundamental limits, we mean the minimal energy per bit required to achieve the target per-user probability of error. The original method proposed by Y. Polyanskiy (2017) and based on Gallager’s trick does not work well for binary signaling. We ...

Today's internet is almost wholly dependent on data originated by limited accuracy, time, and attention humans. If computers can access to accurate information about things, they would be able to count, track, and predict everything. If everything is connected to internet, the gap between our physical world and cyberspace will be reduced. Research activities are ...
