  In this letter, we design a downlink multi-user communication framework based
on Rate-Splitting Multiple Access (RSMA) for semantic-aware networks. First, we
formulate an optimization problem to obtain the optimal user scheduling,
precoding, and power allocation schemes jointly. We consider the metric Age of
Incorrect Information (AoII) in the objective function of the formulated
problem to maximize the freshness of the overall information to be transmitted.
Using big-M and Successive Convex Approximation (SCA) methods, we convert the
resulting non-convex problem with conditional objective and constraints into a
convex one and propose an iterative algorithm to solve it. By numerical
results, we show that RSMA achieves a lower AoII than SDMA owing to its
superior performance under multi-user interference.
