Depending on different combinations of all these different parameters, 22 different oper- ation modes are defined for Type A devices (A0­A21), 5 different operation modes are defined for Type B devices (B0­B4), and 3 different operation modes are defined for Type C devices (C0­C2). Mode-dependent parameters for Type A devices and corresponding data rates for different channel-bonding approaches are summarized in Table 2.9. The base data rates assume a cyclic prefix length of zero, N B denotes the number of bonded channels, R CC denotes the CC code rate, N TDS denotes the time domain spreading factor, and N tl
