5.31 The schemata in no. 4.31 also then have a meaning [Bedeutung], if “p,” “q,” “r,” etc. are not elementary propositions.

And it is easy to see that the propositional sign in no. 4.42, even if “p” and “q” are truth-functions of elementary propositions, expresses a single truth-function of elementary propositions.

Is this easy to see? And doesn’t this all still depend on the idea of elementary propositions?

Fahrnkopf (p. 41) says that this is the only place in the Tractatus where 'Bedeutung' is used not in connection with objects (but rather in "a wide, non-technical sense").
