How to Remap table during import?

REMAP TABLE/SCHEMA/TABLESPACE parameter, Like you want to import a table from your existing logical backup (export backup), but the table already exists. So in this situation, how to import that table because, so in this case you can import this table with another name using REMAP_TABLE parameter.
