SIB5: Cell-reselection parameters for INTER-Frequency

• contains information relevant only for inter-frequency cell re-selection i.e. information about other E‑UTRA frequencies and inter-frequency neighbouring cells relevant for cell re-selection
• includes cell re-selection parameters common for a frequency as well as cell specific re-selection parameters

Signalling radio bearer: N/A
RLC-Mode: TM
Logical channel: BCCH
Direction: E‑UTRAN to UE

Important contents of SystemInformationBlockType5

InterFreqCarrierFreqInfo	can be specified upto 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 candiate cell is greater then 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 candiate cell is greater then threshX_Low and RSRP of serving cell is less than the value of ThreshServingLow singalled within SIB3 # Value 0 to 31 dB. Actual value= Signaled value * 2
allowedMeasBandwidth	defined in terms of Resouce blocks associated with a specific channel bandwidth
cellReselectionPriority	defines the Abolute 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
interFreqBlackCellList	the mentioned cells are no considered for cell reselection
