Energy-Efficient Resource Allocation for Six-Dimensional Movable Antenna Systems

Ziyun Zhang, Ruotong Zhao, Shaokang Hu, Derrick Wing Kwan Ng

This paper investigates the energy-efficiency (EE) maximization problem for a multiuser wireless network equipped with six-dimensional movable antennas (6DMAs), where the three-dimensional (3D) positions and orientations of the antennas are jointly optimized to fully exploit the…

Pinching Antenna-Assisted ISAC with Waveguide Mode Selection

Ruotong Zhao, Yijia Zhang, Shaokang Hu, Derrick Wing Kwan Ng

Conventional pinching antenna (PA)-assisted integrated sensing and communication (ISAC) architectures typically assume static receiver locations or predetermined receive waveguides, thereby underutilizing the inherent spatial degrees of freedom. This paper proposes a novel mode-s…
