A method for coding video data, the method comprising: coding a plurality of texture view blocks of a texture view component, wherein the plurality of texture view blocks corresponds to a single depth view block of a depth view component; if a texture view block of the plurality of texture view blocks that corresponds to at least one partition of the single depth view block is partitioned into a plurality of texture view block partitions: determining which one of the plurality of texture view block partitions encompasses at least a same area relative to the texture view block as where the at least one partition of the single depth view block is located relative to the single depth view block; selecting the determined one of the plurality of texture view block partitions; and determining a reference index of the at least one partition of the single depth view block based on a reference index of the selected texture view block partition; and coding the single depth view block based on the determined reference index, wherein the depth view component and the texture view component belong to a same view within an access unit, wherein the single depth view block indicates relative depth of all pixels within the corresponding plurality of texture view blocks, and wherein a spatial resolution of the depth view component is a quarter of a spatial resolution, which is half width and half height, of the texture view component. coding a plurality of texture view blocks of a texture view component, wherein the plurality of texture view blocks corresponds to a single depth view block of a depth view component; if a texture view block of the plurality of texture view blocks that corresponds to at least one partition of the single depth view block is partitioned into a plurality of texture view block partitions: determining which one of the plurality of texture view block partitions encompasses at least a same area relative to the texture view block as where the at least one partition of the single depth view block is located relative to the single depth view block; selecting the determined one of the plurality of texture view block partitions; and determining a reference index of the at least one partition of the single depth view block based on a reference index of the selected texture view block partition; and determining which one of the plurality of texture view block partitions encompasses at least a same area relative to the texture view block as where the at least one partition of the single depth view block is located relative to the single depth view block; selecting the determined one of the plurality of texture view block partitions; and determining a reference index of the at least one partition of the single depth view block based on a reference index of the selected texture view block partition; and coding the single depth view block based on the determined reference index, wherein the depth view component and the texture view component belong to a same view within an access unit, wherein the single depth view block indicates relative depth of all pixels within the corresponding plurality of texture view blocks, and wherein a spatial resolution of the depth view component is a quarter of a spatial resolution, which is half width and half height, of the texture view component.
