4.5.4 Radio Configuration and Channel Support

I. Radio configuration (RC)
Um interface supports cdma2000 1X, and is compatible with IS -95A/B. The
spreading rate is 1.2288Mcps.
The cdma2000 1X physical layer supports multiple radio configurations. Each radio
configuration supports the frames of the different rate sets, and possesses different
channel
transmission combinations include:
Forward RC1, and reverse RC1;
l
Forward RC2, and reverse RC2;
l
Forward RC3 or RC4, and reverse RC3;
l
Forward RC5, and reverse RC4.
l
With the different RC, cdma2000 1X presents different capabilities. RC1 and RC2
are compatible with IS -95A/B.
Each RC supports different traffic channel data rate. The specific data rates are
listed in Table 4-1 and Table 4-2.
