Method and device for gain adjustment in mobility measurements

A device for gain adjustment in mobility measurements of a user equipment (UE), the device comprising:

• a receiving circuit configured to receive a plurality of signal streams from a plurality of radio cells;
• a selection circuit configured to select a signal stream of the plurality of received signal streams for mobility measurements;
• a mobility measurement circuit configured to perform a mobility measurement on the selected signal stream based on a given gain;
• a signal strength measurement circuit configured to perform a received signal strength measurement of the selected signal stream;
• a gain update circuit configured to determine a gain update of the selected signal stream based on the performed received signal strength measurement of the selected signal stream;
• and
• a recovery circuit configured to initiate a recovery of the mobility measurement based on the gain update if the gain update is outside a predetermined gain range.

A user equipment (UE) comprising:

• a receiver circuit configured to receive a plurality of signal streams from a plurality of radio cells;
• and
• a baseband circuit configured to:
• select a signal stream of the plurality of received signal streams for mobility measurements;
• perform a mobility measurement on the selected signal stream based on a given gain;
• determine a gain update of the selected signal stream based on a received signal strength measurement of the selected signal stream;
• and
• initiate a recovery of the mobility measurement based on the gain update if the gain update is outside a predetermined gain range.
