Surely you can’t use the same antennae for two different operations at the same time…
The noise would be unsalvageable and you would lose packets, surely.

On different bands you can with basic filters. On the same band it would admittedly be tough (unless the band is super wide like the 6E band). It is done by radio repeaters for example but they do need big bulky filters, that kind of thing would not work on a laptop. But it is possible to transmit and receive on the same antenna at the same time, it's not a technical limitation. You just need a good enough filter.
I mean background scanning only has to be a read operation, shouldn't that make it simpler?
Also things these days often have multiple antennas.
Also for 2.4ghz I believe Bluetooth shares the same channels. I've noticed that my BT headphones reach longer in no-wifi/few wifi locations.
