Cell-Free MIMO with Rotatable Antennas: When Macro-Diversity Meets Antenna Directivity
Xingxiang Peng, Qingqing Wu, Ziyuan Zheng +5
Cell-free networks leverage distributed access points (APs) to achieve macro-diversity, yet their performance is often constrained by large disparities in channel quality arising f…
Semi-Passive IRS Enabled Sensing with Group Movable Sensors
Qiaoyan Peng, Qingqing Wu, Wen Chen +4
The performance of the sensing system is limited by the signal attenuation and the number of receiving components. In this letter, we investigate the sensor position selection in a…
Cramér-Rao Bound Optimization for Fluid Antenna-Empowered Integrated Sensing and Uplink Communication System
Yuan Guo, Wen Chen, Qingqing Wu +2
Integrated sensing and communication (ISAC) is a promising solution for the future sixth-generation (6G) system. However, classical fixed-position antenna (FPA) ISAC systems fail t…
Movable Antenna Enhanced Networked Integrated Sensing and Communication System
Yuan Guo, Wen Chen, Qingqing Wu +5
Integrated sensing and communication (ISAC) is a key technology for future 6G networks. Most existing studies focus on monostatic and/or bistatic setups with limited coverage and c…
Near-Field Codebook-Based 3D Spherical Channel Estimation for UCA XL-MIMO Systems
Chenliang Yang, Guangchi Zhang, Miao Cui +2
Extremely large-scale multiple input multiple output (XL-MIMO), a key technology for 6G communications, faces challenges in near-field channel estimation due to spherical wavefront…
QoE Maximization for Multiple-UAV-Assisted Multi-Access Edge Computing via an Online Joint Optimization Approach
Long He, Geng Sun, Zemin Sun +5
In disaster scenarios, conventional terrestrial multi-access edge computing (MEC) paradigms, which rely on ground infrastructure, may become unavailable due to infrastructure damag…
