77 LTE measurements: RSRQ Reference Signa Received Quaity RSRQ = RSRP RSSI Definition Appicabe for Reference Signa Received Quaity (RSRQ) is defined as the ratio N RSRP/(E- UTRA carrier RSSI), where N is the number of RB s of the E-UTRA carrier RSSI measurement bandwidth. The measurements in the numerator and denominator sha be made over the same set of resource bocks. E-UTRA Carrier Received Signa Strength Indicator (RSSI), comprises the inear average of the tota received power (in [W]) observed ony in OFDM symbos containing reference symbos for antenna port 0, in the measurement bandwidth, over N number of resource bocks by the UE from a sources, incuding co-channe serving and non-serving ces, adjacent channe interference, therma noise etc. The reference point for the RSRQ sha be the antenna connector of the UE. If receiver diversity is in use by the UE, the reported vaue sha not be ower than the corresponding RSRQ of any of the individua diversity branches.
