Meaning: Indicates the RSRP threshold for event A4
related to coverage-based inter-frequency handover.
When the measured RSRP value exceeds this
threshold, event A4 is reported. The value of this
parameter is also used as the RSRP threshold for event
A4 related to distance-based, UL-power-based, or
SPID-based inter-frequency handover back to the
HPLMN.

Meaning: This parameter specifies the offset to
CarrAggrA4ThdRsrp. When a CA UE treats the cell
specified by the LocalCellId parameter in the local
eNodeB as its PCell, the UE reports event A4
pertaining to the candidate SCell specified by the
SCelleNodeBId and SCellLocalCellId parameters to
the eNodeB if the RSRP for the candidate SCell
exceeds the sum of the CarrAggrA4ThdRsrp and
SCellA4Offset parameter values. If the sum is greater
than –43 dBm or less than –140 dBm, the threshold
for event A4 takes the value –43 dBm or –140
dBm, respectively.
GUI Value Range: -35~62
Unit: dBm
