1. An apparatus configured to code video information, the apparatus comprising: a memory configured to store a candidate list which comprises at least one base layer motion vector candidate; and a processor in communication with the memory, the processor configured to: determine a behavior for generating said at least one base layer motion vector candidate; generate said at least one base layer motion vector candidate for a current prediction unit (PU) in a particular coding unit (CU) according to the determined behavior, the particular CU having one or more PUs; and add said at least one base layer motion vector candidate to the candidate list.
