Hi Guys. Finally I found the solution!!!!
I leave for you the solution that I found:
<?php
if( have_rows('repeater_field_name') ):
while( have_rows('repeater_field_name') ): the_row();
$tax_val = get_sub_field('taxonomy_sub_field_name');
$taxonomy = 'custom_taxonomy_name';
$term_name = get_term($tax_val, $taxonomy);
if( $tax_val ): echo $term_name->name;
endif;
endwhile;
endif;
?>
