Movable antennas (MAs) boost sensing capabilities by exploiting the extra degrees of freedom (DoFs) through flexible positioning. The design of MA arrays is typically challenged by directional uncertainty, where the target’s precise angle is unknown. To address this, we propose a region-oriented design framework focusi...

The openness and disaggregation of Open radio access network (O-RAN) facilitate resource sharing and coordination across networks, creating new demands for efficient and trustworthy cross-operator scheduling. However, such scheduling is beyond the scope and capability of conventional proportional fair scheduling (PFS),...

Channel charting (CC) is a self-supervised learning technique which aims to construct a lower-dimensional representation of the channel measurements, while preserving the neighboring relationship of users. In this letter, we propose a machine learning approach for radio-based localization task with the aid of CC, which...

Orthogonal frequency division multiplexing (OFDM) is widely adopted in modern wireless systems for high spectral efficiency, yet its high peak-to-average power ratio (PAPR) limits power amplifier efficiency. Mixed-numerology transmission, which enables flexible subcarrier spacing for diverse services, further aggravate...
