Laravel Sorting Data with Relationship and Pagination

I need sorting the Records data according to Relationship.

I am trying below Query.

$data = Lead::with('bdm', status_code',bdm.bdm')->get()->sortByDesc('bdm.bdm.name');

It works fine but I need data with pagination which is giving by Laravel 5 by default.

So If I am trying with below query . It is giving error.

$data = Lead::with('bdm', status_code',bdm.bdm')->pagination(20)->sortByDesc('bdm.bdm.name');

So kindly can anyone give me solution how to adjust this query.

Any Help will be appreciated.

Thanks
