intermodulation characteristic....BT/WLAN

can someone explain me the meaning of following condition?

The reference sensitivity (-70dBm) performance, BER=0.1%, shall be
met under the following condition

The wanted signal at frequency fo with power level 6dB over the reference
sensitivity level

thanks

is it like that if sensistivity is -80dBm then o/p at that freq should be greater than 6dB that is -74dBm?

In general the tests that specify a wanted signal there exist also an unwanted signal (interferer).

For example for Adjacent Channel or Blocking tests (using interferers) the wanted signal should be increased a few dB above the reference sensitivity level.
