Radio Configurations (RC)

A set of Forward Traffic and Reverse Traffic Channel transmission

formats that are characterized by Physical Layer parameters such as

transmission rates, modulation characteristics, and spreading rate

IS-2000 defines Radio Configurations:

– RC1 and RC2 correspond to IS-95 A/B Rate Set 1 and Rate Set 2,

respectively

– RC3 through RC9 on the Forward link

– RC3 through RC6 on the Reverse link

Radio Configurations (RC)

Radio Configurations

A Radio Configuration (RC) defines the following characteristics of a Forward or Reverse Traffic

Channel:

Rate Set

Spreading Rate

Channel Coding (Turbo or convolutional)

Channel Coding Rate

Modulation (QPSK or BPSK)

Transmit Diversity Allowed
