TL;DR
The proposed iterative closed-form solution improves spectral efficiency by 70% compared to the half-duplex (HD) algorithm under low self-interference intensity, and outperforms the SLNR and SCAMP algorithms by 5% and 7%, respectively.
An effective CSI (ECSI) feedback framework is proposed in which UEs compute their linear combiners from precoded downlink pilots, construct corresponding post-combining effective channels, and report compact quantized representations using the same payload structure as in conventional schemes.

Cell-Free MIMO integrated sensing and communication (CF-ISAC) systems can improve the capabilities of communication and sensing by utilizing distributed access points (APs). However, the imperfect channel state information (CSI) weakens the efforts of beamforming designs, resulting in performance degradation of CF-ISAC...

A unified RIS-RSMA optimization framework for asynchronous downlink CF-MIMO and targeted comparisons using WMMSE and regularized zero-forcing private precoders, together with the common-power allocation results, support the need for joint common/private precoder design.

Joint beamforming optimization is a fundamental challenge in achieving efficient integrated sensing and communication (ISAC) for cell-free massive multiple-input multiple-output (MIMO) systems. In the beamforming-vector domain, the design problem is nonconvex because both the transmit-side sensing objective and the use...
