Rate Splitting for General Multicast
Lingzhi Zhao, Ying Cui, Sheng Yang +3
Immersive video, such as virtual reality (VR) and multi-view videos, is growing in popularity. Its wireless streaming is an instance of general multicast, extending conventional un…
Robust Optimization of Instantaneous Beamforming and Quasi-static Phase Shifts in an IRS-assisted Multi-Cell Network
Yuhang Jia, Ying Cui, Wuyang Jiang
The impacts of channel estimation errors, inter-cell interference, phase adjustment cost, and computation cost on an intelligent reflecting surface (IRS)-assisted system are severe…
ML and MAP Device Activity Detections for Grant-Free Massive Access in Multi-Cell Networks
Dongdong Jiang, Ying Cui
Device activity detection is one main challenge in grant-free massive access, which is recently proposed to support massive machine-type communications (mMTC). Existing solutions f…
Joint Optimization of Preamble Selection and Access Barring for MTC with Correlated Device Activities
Wang Liu, Ying Cui, Lianghui Ding +4
Most existing works on random access for machine-type communication (MTC) assume independent device activities. However, in several Internet-of-Things (IoT) applications, device ac…
Optimal Streaming of 360 VR Videos with Perfect, Imperfect and Unknown FoV Viewing Probabilities
Lingzhi Zhao, Ying Cui, Chengjun Guo +1
In this paper, we investigate wireless streaming of multi-quality tiled 360 virtual reality (VR) videos from a multi-antenna server to multiple single-antenna users in a multi-carr…
Optimal Wireless Streaming of Multi-Quality 360 VR Video by Exploiting Natural, Relative Smoothness-enabled and Transcoding-enabled Multicast Opportunities
Kaixuan Long, Ying Cui, Chencheng Ye +1
In this paper, we would like to investigate optimal wireless streaming of a multi-quality tiled 360 virtual reality (VR) video from a server to multiple users. To this end, we prop…
