1. A method of video coding, the method comprising: obtaining a reference picture list associated with a current prediction unit; obtaining a candidate reference picture list from a plurality of candidate reference picture lists associated with a co-located prediction unit that is co-located with the current prediction unit; determining whether a motion vector scaling operation is associated with using the candidate reference picture list as a motion vector prediction reference picture list associated with the co-located prediction unit; and selecting the motion vector prediction reference picture list associated with the co-located prediction unit from the plurality of candidate reference picture lists based on the determining.
