NOMA-Based Coexistence of Near-Field and Far-Field Massive MIMO Communications
Zhiguo Ding, Robert Schober, H. Vincent Poor
This letter considers a legacy massive multiple-input multiple-output (MIMO) network, in which spatial beams have been preconfigured for near-field users, and proposes to use the n…
Joint Beamforming and Antenna Movement Design for Moveable Antenna Systems Based on Statistical CSI
Xintai Chen, Biqian Feng, Yongpeng Wu +2
This paper studies a novel movable antenna (MA)-enhanced multiple-input multiple-output (MIMO) system to leverage the corresponding spatial degrees of freedom (DoFs) for improving…
Movable Antenna-Enhanced Multiuser Communication: Optimal Discrete Antenna Positioning and Beamforming
Yifei Wu, Dongfang Xu, Derrick Wing Kwan Ng +2
Movable antennas (MAs) are a promising paradigm to enhance the spatial degrees of freedom of conventional multi-antenna systems by flexibly adapting the positions of the antenna el…
NOMA-Assisted Grant-Free Transmission: How to Design Pre-Configured SNR Levels?
Zhiguo Ding, Robert Schober, Bayan Sharif +1
An effective way to realize non-orthogonal multiple access (NOMA) assisted grant-free transmission is to first create multiple receive signal-to-noise ratio (SNR) levels and then s…
Optimal Transmit Antenna Deployment and Power Allocation for Wireless Power Supply in an Indoor Space
Kenneth M. Mayer, Laura Cottatellucci, Robert Schober
As Internet of Things (IoT) devices proliferate, sustainable methods for powering them are becoming indispensable. The wireless provision of power enables battery-free operation an…
Integrated Sensing, Navigation, and Communication for Secure UAV Networks with a Mobile Eavesdropper
Zhiqiang Wei, Fan Liu, Chang Liu +3
This paper proposes an integrated sensing, navigation, and communication (ISNC) framework for safeguarding unmanned aerial vehicle (UAV)-enabled wireless networks against a mobile…
