I'm confused by your use of the word "base station". Do you mean that
someone else has an access point that is reconfiguring to offer the same
SSID on the same channel as your AP, or do you mean that there is an
unauthorized client trying to associate with your SSID?
If you are running WPA, an anauthorized client should not be able to
associate, and therefore is not worth worrying about. I'd keep my eye on it,
but if you don't see unexplained activity on your network you needn't be too
concerned. Just periodically check to be sure that no unauthorized client is
associated. You can use MAC filtering if you want, but it won't really help
much (it can be spoofed).
If it's another AP trying to offer the same SSID on the same channel, than
any of your authorized clients should fail to associate with it because it
is not configured for your WPA preshared key.
At worst, it sounds like a potential denial-of-service attack. Is the signal
so strong that you can't get on to your own net, or your bitrate is
degraded? If not, I wouldn't waste much time worrying about them. I don't
see how they could harm you.
