Age of Information in Downlink Systems: Broadcast or Unicast Transmission?
Zhifeng Tang, Nan Yang, Parastoo Sadeghi +1
We analytically decide whether the broadcast transmission scheme or the unicast transmission scheme achieves the optimal age of information (AoI) performance of a multiuser system…
An Unsupervised Learning Approach for Spectrum Allocation in Terahertz Communication Systems
Akram Shafie, Chunhui Li, Nan Yang +2
We propose a new spectrum allocation strategy, aided by unsupervised learning, for multiuser terahertz communication systems. In this strategy, adaptive sub-band bandwidth is consi…
Novel Spectrum Allocation Among Multiple Transmission Windows for Terahertz Communication Systems
Akram Shafie, Nan Yang, Chong Han +1
This paper presents a novel spectrum allocation strategy for multiuser terahertz (THz) band communication systems when the to-be-allocated spectrum is composed of multiple transmis…
Dynamic-subarray with Fixed Phase Shifters for Energy-efficient Terahertz Hybrid Beamforming under Partial CSI
Longfei Yan, Chong Han, Nan Yang +1
Terahertz (THz) communications are regarded as a pillar technology for the 6G systems, by offering multi-ten-GHz bandwidth. To overcome the huge propagation loss while reducing the…
