Narrative:

We were on approach vectors for runway 4L at jfk in visual clear conditions. The approach controller notified us of a heavy aircraft on approach for 4R. Our vector would place us in a position to cross the wake of the heavy aircraft. Unfortunately I cannot remember specifically what our approach clearance was however I believe that we descended into the wake remnant area of the heavy aircraft. I don't recall encountering wake turbulence but I do know we were advised of the possibility. Unfortunately I do not recall the approach clearance specifics but it is possible that I read back acceptance of a clearance that did not involve an altitude clearance limit and thus violated that limit.
