InterFreqCarrierFreqInfo
can be specified up to 8 carrier frequencies
dl-CarrierFreq
carrier frequency helps the UE to search the cells
q-RxLevMin
Minimum RSRP value of the inter-frequency cell. Value -70 to
-22 dBm.
Actual value: signalled value * 2
p-Max
maximum allowed UL transmit power of the cell
t-ReselectionEUTRA
Defines the time to trigger for cell reselection. Value 0 to 7 sec.
t-ReselectionEUTRA-SF
scaling factors for Medium and High mobility
threshX-High
# Threshold (in dB) used by UE for cell re-selection to a HIGHER priority
#  The Srxlev of the candidate cell is greater than threshX_High
# Value 0 to 31 dB. Actual value= Signaled value * 2
threshX-Low
# Threshold (in dB) used by UE for cell re-selection to a LOWER priority
#  Cell re-selection is allowed only when Srxlev of the candidate cell is greater than threshX_Low and RSRP of serving cell is less than the value of ThreshServingLow signalled within SIB3
# Value 0 to 31 dB. Actual value= Signaled value * 2
allowedMeasBandwidth
defined in terms of Resource blocks associated with a specific channel bandwidth
cellReselectionPriority
defines the Absolute priority of the frequency layer
neighCellConfig
information regarding the neighbouring cells
q-OffsetFreq
defines the RSRP measurement offset, applied to all cells on the specified RF carrier
intraFreqBlackCellList
the mentioned cells are no considered for cell reselection
