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…
Analysis and Optimization of Successful Symbol Transmission Rate for Grant-free Massive Access with Massive MIMO
Gang Chen, Ying Cui, Hei Victor Cheng +2
Grant-free massive access is an important technique for supporting massive machine-type communications (mMTC) for Internet-of-Things (IoT). Two important features in grant-free mas…
Analysis and Optimization of Outage Probability in Multi-Intelligent Reflecting Surface-Assisted Systems
Zijian Zhang, Ying Cui, Feng Yang +1
Intelligent reflecting surface (IRS) is envisioned to be a promising solution for designing spectral and energy efficient wireless systems. In this letter, we study a multi-IRS-ass…
Low Complexity Algorithms for Robust Multigroup Multicast Beamforming
Guangda Zang, Hei Victor Cheng, Ying Cui +4
Existing methods for robust multigroup multicast beamforming obtain feasible points using semidefinite relaxation (SDR) and Gaussian randomization, and have high computational comp…
