Well, the title of the question is the question itself :P
I have been looking for the answer into the 802.11-2007 and 2012 standards, but I didn't find anything.
Hope you'll be able to help me with this.
I supose that maybe must be a combination of flag values in the MAC (Medium Access Control) header, which determines if the frame needs to carry the LLC header.

An 802.11 frame should contain an LLC header if, and only if, it's a Data frame. The frame type and subtype are part of the Frame Control field in the MAC header; Data is one of the frame type values (the others are Control and Management). The subtype doesn't matter - all Data frames should contain an LLC header, and no other frames should.
