Abstract
In the future communications, cell-free networks are considered very promising, owing to their robustness against inter-cell interference which degrades the user signal-to-interference-plus-noise-ratio (SINR). For an efficient network to achieve an enhanced capacity at a minimized power consumption, reconfigurable intelligent surfaces (RIS) are promoted as a key candidate 6G technology. In this paper, a joint precoding RIS aided cell-free Multiple-Input-Multiple-Output (MIMO) network is considered, where a weighted sum rate (WSR) maximization problem is formulated and decoupled into subproblems. A feasible solution is then obtained using fractional programming (FP). Finally, the performance of passive RIS and active RIS is then compared.
