Can UE perform Measurement reporting if it receives only RSRQ in reportconfig?

reportConfig[1] =ReportConfigInterRAT-B2-UTRA-RSRQ(-12).This report config IE is sent in Measconfig IE within rrc connection reconfiguration.My doubt is if UE reports only RSRQ is it possible to take handover decision by eNB .if possible how?

Basically ENB can have right to ask RSRQ or RSRP to UE in reportconfig. Even RSRQ is also calculated from RSRP.

RSRQ = N x RSRP / RSSI.

AS I know ENB can take decision of handover or not based on RSRQ. This is based on your implementation and how you are maintaining it.

There are following two types of reportConfig supported by an eNodeB for an UE
- Report Configuration for E-UTRAN
- Report Configuration for Inter-RAT

If you check carefully, report configuration related to E-UTRAN is associated with parameters such as RSRP and RSRQ while Inter-RAT report configuration is associated with terms like

ThresholdUTRA ::=                   CHOICE{
    utra-RSCP                           INTEGER (-5..91),
    utra-EcN0                           INTEGER (0..49)
}

ThresholdGERAN ::=              INTEGER (0..63)

ThresholdCDMA2000 ::=           INTEGER (0..63)

So , Event B2 is associated with Inter-RAT. I don't think RSRQ is anyhow related to Inter-RAT B2 event. Please check "MeasResult " sent by UE to eNodeB.
