QoS-Constrained Scheduling in Multi-Cell Multi-User MIMO Networks
Tenghao Cai, Lei Li, Tsung-Hui Chang
In 5G and beyond networks, efficient scheduling is essential to exploit the gains of multi-user MIMO (MU-MIMO) equipped with carrier aggregation and joint transmission (JT). Howeve…
Toward Distributed User Scheduling and Coordinated Beamforming in Multi-Cell mmWave Networks: A Sensing-Assisted Framework
Tenghao Cai, Lei Li, Shutao Zhang +1
Providing guaranteed quality of service for cell-edge users remains a longstanding challenge in wireless networks. While coordinated interference management was proposed decades ag…
Distributed User Scheduling in Multi-Cell MIMO O-RAN with QoS Constraints
Tenghao Cai, Lei Li, Tsung-Hui Chang
Distributed scheduling is essential for open radio access network (O-RAN) employing advanced physical-layer techniques such as multi-user MIMO (MU-MIMO), carrier aggregation (CA),…
Power Minimization in Pinching-Antenna Systems under Probabilistic LoS Blockage
Lei Li, Yanqing Xu, Tenghao Cai +1
With great flexibility to adjust antenna positions, pinching antennas (PAs) are promising for alleviating large-scale attenuation in wireless networks. In this work, we investigate…
