My bedroom that is inside an apartment building. All of walls, ceiling and ground are made of reinforced concrete (concrete with steel).

This is from outside of my bedroom.

For the purpose of soundproofing, I need to build a studwork and install drywall on the walls. how about ceiling? Does installing resilient channel directly to the concrete ceiling reduce the effectiveness of soundproofing? If yes. What kind of layers do I need to add between the concrete ceiling and resilient channel?

Note_1: I am aware that screws, glue could be used to install resilient channels to the ceiling, which is not what I am asking. I am asking for some consideration of soundproofing.

Note_2: I am pretty sure that reinforced concrete transmits sound, because I have been disturbed by the sound from upstairs through ceiling, and that's why I need to install resilient channel to soundproof my ceiling.
