The BIP details how miners can vote for a larger block size limit during a window of 2016 blocks. The block size limit does not increase during this phase. The block size limit is adjusted at the end of the sample window and the new size is valid until the next retargetting. If this wasn't clear, please let me know if I need to clarify any specifics in the wording of the proposal.
