12. The WTRU of claim 11 , wherein the reference picture list associated with the current prediction unit comprises a plurality of reference pictures, and the processor is further configured to: retrieve a reference picture from the reference picture list associated with the current prediction unit; determine whether a motion vector scaling operation is associated with using the reference picture as a motion vector prediction candidate for performing motion vector prediction; and select the motion vector prediction candidate from the reference picture list associated with the current prediction unit based on the determining.
