RADIO NETWORK NODE AND METHOD THEREIN FOR DECIDING AGC MODE FOR A RECEIVED SIGNAL IN A WIRELESS COMMUNICATIONS NETWORK

摘要

A method performed by a radio network node for deciding an Automatic Gain Control (AGC) mode to be used for a received signal in a wireless communications network is provided. The radio network node estimates (301) a type of interference scenario affecting the received signal and obtains (302) information about channel quality of channels between the radio network node and connected wireless devices. Based on the estimated type of interference scenario and the obtained information about the channel quality, the radio network node dynamically decides (303) for the received signal, which AGC mode out of the following ACG modes to be used: - a slow AGC using a release timer for releasing an AGC state, - a fast AGC using a release timer for releasing an AGC state, and - a fast AGC using a trigger timer triggering an AGC state a first time interval before an interference period, and the release timer releasing the AGC state a second time interval after said interference period ends.
