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…
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…
Optimal Hybrid Beamforming for Multiuser Massive MIMO Systems With Individual SINR Constraints
Guangda Zang, Ying Cui, Hei Victor Cheng +3
In this letter, we consider optimal hybrid beamforming design to minimize the transmission power under individual signal-to-interference-plus-noise ratio (SINR) constraints in a mu…
The Performance Analysis of Coded Cache in Wireless Fading Channel
Wei Huang, Sinong Wang, Lianghui Ding +2
The rapid growth of data volume and the accompanying congestion problems over the wireless networks have been critical issues to content providers. A novel technique, termed as cod…
