4.7.1.5 Cell ID
The Cell ID (IDCell) used for preamble selection. The range is from 0 to 31.
4.7.1.6 Segment Number
The segment (BS) number in a three sector BS (0-2).
4.7.1.7 Total Uplink Duration
The total duration of the uplink in a frame, in slots (one slot equals 3 symbols).
To avoid BS-BS interference, the ul-dl-allocation must be identical in all BSs in a
geographical region.
The range is 4-7 or 10 for bandwidth of 5 or 10MHz, 3-5 or 7 for bandwidth of
7MHz.
4.7.1.8 Major Group
The major groups allocated to the BS for maps transmission. Two hexadecimal
digits in the range 00 to fc, representing 8 bits numbered 0 to 7 (left to right). Bits
0 to 5 indicate whether Subchannel Groups 0 to 5 (respectively) are allocated. Bits
6 and 7 are set to 0.
If BW=5 MHz, bits 1, 3 and 5 are not relevant ("don't care"). bits 0, 2, and 4 should
be set. Major Group must be set to A8.
If BW=7/10 MHz with reuse 1, bits 0 to 5 must be set. The value must be set to fc.
For BW=7/10 MHz with Reuse 3:
 If Segment Number = 0, then bits #0 and 1 should be set. The value must be
set to c0.
 If Segment Number = 1, then bits #2 and 3 should be set. The value must be
set to 30.
 If Segment Number = 2, then bits #4 and 5 should be set. The value must be
set to 0c.
4.7.1.9 Basic Map Repetition
The basic repetition used in the transmission of the maps using QPSK 1/2. The
available options are 1, 2, 4 and 6. (1 means no repetitions).
