COD MW single player campaign can't be started?

- in PlayStation
3

I recently got PS4 and COD MW from my brother and installed the game. I started the game and wanted to play the single player campaign but it said: You don't own at least one single player DLC pack. Please download and install it.

What do I have to do now?

Please explain exactly (thanks in advance)
