Carroll has resumed his loan with the Rs after shaking off injury.
He told the Fulham Chronicle: "It's good to be back - and at Loftus Road where the atmosphere is so good.
"No game is easy in this league - but we played some good stuff in the second half in periods - and winning by three is really promising after winning by the odd goal in recent games.
"At the time I was gutted to get injured because it was just starting to come good for me and the England U21s, but now I'm just glad to be back and looking to get more games under my belt.
"I worked with Tim Sherwood on specific things to help me and it helped me last the 90 minutes, which was good."
