Every puppy is different, but I don’t remember my puppies waking me much before 5 AM after the first week. If the puppy is in your room (so you can easily hear him), and if his crate is the right size (just big enough to stand up, turn around, lay down comfortably), then if he wakes up in the night and whimpers, just reassure him that you’re there and see if he’ll go back to sleep. Only get up and take him out if he really sounds desperate. And then just make it a business trip: carry him out (no lovin’), give him a reasonable time on a short leash to take care of business, if he does, praise him quietly, and take him back to his crate. I have NEVER intentionally woken my puppy in the night to take him out! If he needs to go, he’ll let you know... you just need to be sure he’s close enough for you to hear him.
