Let \(\phi \ne S\subseteq R\) be an m-system of a ring R, and let \(\rho \) be a special radical. This study introduces the concept of S- \(\rho \) -ideals in noncommutative rings. This notion extends the previously studied \(\rho \) -ideals and can also be seen as a generalization of the right S-prime ideals. We show how some properties associated with \(\rho \) -ideals have evolved into results within these generalizations. Relationships between S- \(\rho \) -ideals and other types of ideals like \(\rho \) -ideals, right S-prime ideals, and S-finite ideals are shown. We show the behaviour of this notion in related rings. The construction of \((S\boxplus M)\) - \(\rho \) -ideals in idealization rings is presented for an R-R-bimodule M. Additionally, we introduce S- \(\mathcal {P}\) -ideals using Baer-McCoy radical \(\mathcal {P}\) and examine their properties.
