Reference Signal Received Quality

RSRQ is used in LTE networks to determine the quality of the radio channel. RSRQ, unlike RSRP (wanted signal strength), also includes interference level due to the inclusion of RSSI in calculation. This parameter is also used for cell selection and handover, if the RSRP is not sufficient. This happens mainly in border parts of cell.
