LTE: System Information Block Type 5

Direction: E-UTRAN => UE
Signalling Radio Bearer: N/A
RLC Mode: TM
Logical Channel: BCCH
Transport Channel: DL-SCH

The SystemInformationBlockType5 (SIB5) contains neighbor cell related information for inter-frequency cell-reselection i.e. the information about neighbor E-UTRA frequencies

SIB5 includes neighbor cell list, carrier frequency, cell reselection priority, threshold used by the UE when reselecting a higher/lower priority frequency than the current serving frequency etc. It also contains a list of blacklisted inter-frequency neighbouring cells

Reference: 3GPP TS 36.331

Example: SystemInformationBlockType5 message

  1. Hi Swamy,
    I have one doubt, How UE identifies the RS position of its Neighbor cells for measuring RSRP/RSRQ? .
    From the above SIB5 message we can see only dl-carrierfreq of the neighbor cells and as we know RS position is depends on PCI. So will it decode PCI using PSS_SSS for each freq to identify the RS position during Neighbor cell measurement?

  2. what's max value we can keep for t-ReselectionEUTRA?
