Rate-Splitting with Hybrid Messages: DoF Analysis of the Two-User MIMO Broadcast Channel with Imperfect CSIT
Tong Zhang, Yufan Zhuang, Gaojie Chen +4
Most of the existing research on degrees-of-freedom (DoF) with imperfect channel state information at the transmitter (CSIT) assume the messages are private, which may not reflect…
The DoF Region of Order-(K-1) Messages for the K-user MIMO Broadcast Channel with Delayed CSIT
Tong Zhang, Shuai Wang, Taotao Wang +1
This paper theoretically characterizes the degrees-of-freedom (DoF) region of order- messages for the -user multiple-input multiple-output (MIMO) broadcast channel with d…
On Secure Degrees of Freedom of the MIMO Interference Channel with Local Output Feedback
Tong Zhang, Yinfei Xu, Shuai Wang +2
This paper studies the problem of sum-secure degrees of freedom (SDoF) of the (M,M,N,N) multiple-input multiple-output (MIMO) interference channel with local output feedback, so as…
Secure Degrees-of-Freedom of the MIMO X Channel with Delayed CSIT
Tong Zhang, Rui Wang
In this paper, we study the secure degrees-of-freedom (SDoF) characterization for the multiple-input multiple-output (MIMO) X channel with confidential messages and delayed CSIT. I…
Age-of-Information-based Scheduling in Multiuser Uplinks with Stochastic Arrivals: A POMDP Approach
Aoyu Gong, Tong Zhang, He Chen +1
In this paper, we consider a multiuser uplink status update system, where a monitor aims to timely collect randomly generated status updates from multiple end nodes through a share…
Achievable DoF Regions of Three-User MIMO Broadcast Channel with Delayed CSIT
Tong Zhang, Rui Wang
For the two-user multiple-input multiple-output (MIMO) broadcast channel with delayed channel state information at the transmitter (CSIT) and arbitrary antenna configurations, all…
