1. A method for automatic gain control of radio chains of a receiver, the method being performed by the receiver, the method comprising:

  • receiving at least two radio frequency (RF) signals, each RF signal being received on an individual radio chain from an antenna array;

    determining, by comparing the at least two RF signals to a threshold, whether to perform gain control or not of at least one of the at least two RF signals before analog combining of the at least two RF signals;

    sending a notification to a detector regarding whether gain control is performed or not; and

    performing analog combining of the at least two RF signals, thereby generating a single input to the detector.
