Rate-Splitting and Sum-DoF for the K-User MISO Broadcast Channel with Mixed CSIT and Order-(K-1) Messages

Autor: Zheng, Shuo, Zhang, Tong, Li, Jingfu, Wang, Shuai, Yuan, Weijie, Chen, Gaojie, Wang, Rui

In this paper, we propose a rate-splitting design and characterize the sum-degrees-of-freedom (DoF) for the K-user multiple-input-single-output (MISO) broadcast channel with mixed channel state information at the transmitter (CSIT) and order-(K-1) me

DoF Upper Bound on Three-User MISO Broadcast Channel with Two Antennas and Mixed CSIT

Autor: Zheng, Shuo, Zhang, Tong, Wang, Shuai, Chen, Gaojie, Li, Guoliang, Zhao, Shancheng, Wang, Rui

With delayed and imperfect current channel state information at the transmitter (CSIT), namely mixed CSIT, the sum degrees-of-freedom (sum-DoF) in the two-user multiple-input multiple-output (MIMO) broadcast channel and the $K$-user multiple-input si

On DoF of Active RIS-Assisted MIMO Interference Channel with Arbitrary Antenna Configurations: When Will RIS Help?

Autor: Zheng, Shuo, Lv, Bojie, Zhang, Tong, Xu, Yinfei, Chen, Gaojie, Wang, Rui, Ching, P. C.

An active reconfigurable intelligent surface (RIS) has been shown to be able to enhance the sum-of-degrees-of-freedom (DoF) of a two-user multiple-input multiple-output (MIMO) interference channel (IC) with equal number of antennas at each transmitte
