Replacing damaged sub floor
It's called "blocking". You run a 2x4" or wider, perpendicular to the joists and screw both sides of the subfloor into it. Do not remove the subfloor that is under the wall, how would you replace it?
What are your plans after the new subfloor is glued and fastened in place? Make sure you use subfloor grade, exposure 1, exterior glue material that of course is tongue and groove.
