There isn't really a minimum for the connection. However, you will likely find yourself struggling to get matches in any matchmaking activities. It should ultimately come down to the latency (how long it takes information to reach its destination) and stability of your connection. Those 2 factors, on their own or combined, are typically the worst for your ability to maintain a connection to the game.

As for your bandwidth (the amount of information that can be sent at a given time), your 12Mbps download and 3 Mbps upload should suffice. However you may struggle when there are more players, and enemies in your area.
