Unmanned aerial vehicle (UAV)-enabled wireless networks provide flexible coverage for ground users in dynamic and infrastructure-limited scenarios. However, when multiple UAV base stations share the same spectrum, system performance is strongly affected by UAV placement, user association, and co-channel interference. T...

Conventional reconfigurable intelligent surfaces (RIS)-aided cell-free massive multiple-input multiple-output (CF mMIMO) networks are inherently constrained by half-space reflection, which limits coverage expansion and flexible deployment. To overcome this issue, simultaneously transmitting and reflecting reconfigurabl...

The integration of low-altitude mobile edge computing (MEC) and integrated sensing and communication (ISAC) holds immense potential for empowering applications such as aerial inspection and emergency rescue. However, compared to terrestrial networks, low-altitude environments pose severe challenges to sensing robustnes...

The integration of reconfigurable intelligent surface (RIS) technology with cell-free massive MIMO (CF mMIMO) enhances wireless network sum-rate performance. This paper proposes a novel segmented RIS-assisted CF mMIMO architecture for downlink transmission, where RIS elements within each segment share a common reflecti...
