     280  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.

     294  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:
     295
     296  if Permutation Mode = “PUSC”-

     312  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:
