Bluetooth 6.0 boasts that adding Channel Sounding will improve keyless entry between the phone and the cars enabled. The feature will allow developers to “enhance the security” of the digital key with an extra layer that only unlocks a vehicle when connected with an authorized device at a particular distance.

4.1 Two Direction Finding Methods

Bluetooth direction finding offers two distinct architectures or methods, each of which exploits the same underlying basis. The first of the two methods is called Angle of Arrival (AoA) and the second is called Angle of Departure (AoD).

In each case, special direction finding signals are transmitted by one device and the signal is then used by another device to calculate the direction of the received signal.

Using AoA, the receiver contains a multi-antenna array as shown in Figure 3. Using AoD, it is the transmitting device that contains the antenna array, as shown in Figure 4.

I guess that that's going to require an antenna array and independent processing of each antenna then.
