Title: Method and apparatus for transmitting high speed data in a spread spectrum communications system

Abstract: The present invention is a novel and improved method and apparatus for transmitting high speed digital data in a spread spectrum communications system. In particular, the present invention provides methods for transmitting forward link and reverse link high speed digital data. For both forward link and reverse link transmissions, the present invention describes a method for processing the data for transmission in a 1.2288 Mcps band and in a 3.6268 Mcps band. In addition, the present invention describes a method for transmitting forward link and reverse link data of both rate set 1 digital data and rate set 2 digital data. Rate set 1 digital data comprises variable rate data at rates defined as Mux Option 1 in the IS-95 standard. Rate set 2 digital data comprises variable rate data at rates defined as Mux Option 2 in the appendix to the IS-95 standard. In addition the present invention describes methods of transmitting the data for applications using packet switched technology and circuit switched technology.
