7.2.3.13 REM/SON
From the tree menu, select REM/SON to move onto the REM and SON Setup page. There are four different
functional sections related to REM and SON.
First, you can select REM Scan by selecting ‘Scan ff Boot’ at Opmode of ‘REM Scan Configuration’ section. In
this case, DL earfcn values should be provided at DL EARFCNs to be scanned. The list of DL earfcn values can
be added followed by comma. (Com
ma separated). If you select ‘Add to Neighbor Table’ option ‘Enable’, the REM
scanned cells are added/updated to ANR. If it is disabled, the scanned cell information is only stored inner
database for REM and isn’t applied to the ANR.
Click the ‘Save’ button to apply all the setting you made so far. The saved setting will be applied when the small
cell is rebooted. If you don’t want to have REM scan option, you can make Opmode ‘Disable’. In this case, you
can also click ‘save’ button to apply your change.
PCI Collision/Confusion Detection setting is provided. You can select Collision Alarm and Confusion Alarm by
selecting each option ‘Enable’ individually.
PCI Auto Allocation setting provides PCI auto allocation function. When it is enabled by selecting ‘Enable’ at ‘Auto
Allocation’, the PCI Auto Allocation function provides the best PCI among the provided PCIs from ‘Available PCI
List’ automatically. The PCI allocation algorithm selects the best PCI for avoiding PCI collision /confusion and
maximizing the PCI reuse distance and reducing the interference of UL channel estimation. The ‘Available PCI
List’ should be provided for the ‘Auto Allocation’ is ‘Enable’. The values are comma separated.
RACH Optimization setting provides the best Root Sequence Index by the RACH Optimization algorithm. The
RACH optimization algorithm offers the best possible unique root sequence to reduce the ghost preamble
detection prob
lem. In this case, you should insert Root sequence Index Range on ‘Root Sequence Index Range
Start’ and ‘Root Sequence Index Range End’ with first and the last numbers of the range. The number should be
in between 1 and 837.
