4.8.2.2.5 Channelization
The Channelization submenu enables viewing/updating the following parameters:
 DL Permutation Base
 DL Permutation Base Value
 UL Permutation Base
 UL Permutation Base Value
 Major Group
4.8.2.2.5.1 DL Permutation Base
The method for configuring/calculating the permutation base used for downlink
sub-channelization.
The available options are Fix, Variable and Rotated.
 Fix: The permutation base is defined by the DL Permutation Base Value
parameter (see below).
 Variable: The formula is (4*Cell number + Segment number) modulo 32.
 Rotated: The formula starts with (4*Cell number + Segment number) modulo
32 (the same as for Variable), incremented by 1 (modulo 32) each frame.
The default is Fix.
In the current release only the Fix option is supported.
4.8.2.2.5.2 DL Permutation Base Value
The value of the downlink permutation base for Fix DL Permutation Base.
The range is from 0 to 31.
The default is 0.
4.8.2.2.5.3 UL Permutation Base
The method for configuring/calculating the permutation base used for uplink
sub-channelization.
The available options are Fix, Variable and Rotated.
