The sectors in a base station working in LTE only mode are numbered from L1 in a
numerical order, for example L1 and L2. Low-frequency sectors are numbered from L1 to
L6, and high-frequency sectors are numbered from L7 to L12.
The slots are numbered from 0 in a numerical order, for example slot 0, slot 1, and slot 2.
A slot can be identified through cabinet number+slot number, for example, slot 1 in cabinet
1 (primary RFC).
When LRFUs are configured, they are preferentially positioned in the slots in cabinet 1.
That is, the LRFU configured for L1 is preferentially positioned in slot 0 and then slot 1 if
slot 0 is occupied. The LRFU configured for L2 is preferentially positioned in slot 2 and
then slot 3 if slot 2 is occupied. The LRFU configured for L3 is preferentially positioned
in slot 4 and then slot 5 if slot 4 is occupied.
When MRFUs are configured, they are preferentially positioned in the slots in cabinet 1.
That is, the MRFU configured for L1 is preferentially positioned in slot 0 and then slot 1
if slot 0 is occupied. The MRFU configured for L2 is preferentially positioned in slot 2 and
then slot 3 if slot 2 is occupied. The MRFU configured for L3 is preferentially positioned
in slot 4 and then slot 5 if slot 4 is occupied.
