Age of Information Optimization in Multi-Channel Network with Sided Information
Yuchao Chen, Jintao Wang, Xiaoqing Wang +1
We consider a discrete-time multi-channel network where the destination collects time-sensitive packets from multiple sources with sided channel information. The popular metric, Ag…
Enhanced Tracking and Beamforming Codebook Design for Wideband Terahertz Massive MIMO System
Xu Shi, Jintao Wang, Jian Song
True-time-delay (TTD) lines are recently applied inside Terahertz (THz) hybrid-precoding transceiver to acquire high beamforming gain against beam squint effect. However, beam trac…
Better Lightweight Network for Free: Codeword Mimic Learning for Massive MIMO CSI feedback
Zhilin Lu, Xudong Zhang, Rui Zeng +1
The channel state information (CSI) needs to be fed back from the user equipment (UE) to the base station (BS) in frequency division duplexing (FDD) multiple-input multiple-output…
Spatial-chirp Codebook-based Hierarchical Beam Training for Extremely Large-Scale Massive MIMO
Xu Shi, Jintao Wang, Zhi Sun +1
Extremely large-scale multiple-input multiple-output (XL-MIMO) promises to provide ultrahigh data rates in millimeter-wave (mmWave) and Terahertz (THz) spectrum. However, the spher…
RIS-Aided MIMO Systems with Hardware Impairments: Robust Beamforming Design and Analysis
Jintao Wang, Shiqi Gong, Qingqing Wu +1
Reconfigurable intelligent surface (RIS) has been anticipated to be a novel cost-effective technology to improve the performance of future wireless systems. In this paper, we inves…
Sending Timely Status Updates through Channel with Random Delay via Online Learning
Haoyue Tang, Yuchao Chen, Jintao Wang +2
In this work, we study a status update system with a source node sending timely information to the destination through a channel with random delay. We measure the timeliness of the…
