Basestation frequency in KHz. Two distinct frequency ranges are supported:

Mid 2.5 GHz 2498500 - 2687500
3.5 GHz 3402500 - 3597500


Bandwidth mode: 0 = 10 MHz, 2 = 7 MHz, 1 = 5 MHz (Default is 0 = 10 MHz). When specifying bandwidth, frequency should match ranges in the following table:

10 MHz (bwmode=0) 7 MHz (bwmode=2) 5 MHz (bwmode=1)
2501000 - 268500
3405000 - 3595000
3403500 - 3596500 2498500 - 2687500
3402500 - 3597500

When changing bwmode, you may also need to change other settings (such as ttg, rtg, dlulratio) that depend on bandwidth mode in the WiMAX profiles released by the WiMAX forum.


Ratio of uplink and downlink OFDM symbols in the frame. The frame duration is dependent on the bandwidth

10 MHz (bwmode=0) 7 MHz (bwmode=2) 5 MHz (bwmode=1)
0x00 → DL=35, UL=12 0x00 → DL=24, UL=09 0x00 → DL=35, UL=12
0x01 → DL=32, UL=15 0x01 → DL=21, UL=12 0x01 → DL=32, UL=15
0x02 → DL=29, UL=18 0x02 → DL=18, UL=15 0x02 → DL=29, UL=18
0x03 → DL=26, UL=21 0x03 → DL=26, UL=21


Transmit Receive Transition Gap (TTG value) in units of PS (physical slots). This is the gap between the downlink burst and the subsequent uplink burst in a TDD transceiver. During TTG, the BS switches from transmit to receive mode and SSs switch from receive to transmit mode. These are specified by the WiMAX profiles released by the WiMAX forum. The recommended value depends on the settings of bandwidth mode (bwmode), ratio of uplink and downlink symbols (dlulratio), and permutation mode (permutation) as follows:

if Permutation Mode = “PUSC”-

ttg bwmode dlulratio
296 10 MHz (0) 35,12 (0x00) or 29,18 (0x02)
584 10 MHz (0) 32,15 (0x01) or 26,21 (0x03)
148 5 MHz (1) 35,12 (0x00) or 29,18 (0x02)
292 5 MHz (1) 32,15 (0x01) or 26,21 (0x03)
376 7 MHz (2) 21,12 (0x01)
664 7 MHz (2) 24,09 (0x00) or 18,15 (0x02)

if Permutation Mode = “FUSC” -

ttg bwmode
148 5 MHz (1)
376 7 MHz (2)
296 10 MHz (0)


Receive Transmit Transition Gap (RTG value) in units of PS (physical slots). This is the gap between the uplink burst and the subsequent downlink burst in a TDD transceiver. During RTG, the BS switches from receive to transmit mode and SSs switch from transmit to receive mode. The recommended value depends on the bandwidth mode (bwmode) setting, as follows:

rtg bwmode
84 5 MHz (1)
120 7 MHz (2)
168 10 MHz (0)


Two permutation modes are allowed:

0 —> PUSC (partial usage of subchannels) 1 —> FUSC (full use of subchannels)

Other settings (e.g. ttg) may need to be changed if you change permutation mode.

N.B. HARQ can only be enabled if the permutation mode is PUSC.
