Abstract

본 발명은 CDMA방식의 이동통신 시스템에서 데이타 전송속도를 가변하기 위한 방식에 관한 것으로 특히, 임의의 전송속도를 기준으로하여 가입자의 채널을 구분하는데 사용되는 직교코드를 전송데이타 속도가 증가되는 양만큼 쌍단위로 할당하는 제1과정과, 상기 제1과정에서 할당된 직교코드의 쌍을 이루는 소정갯수의 채널중 하나의 채널만을 사용하여 전송데이타를 대역확산시켜 송신하는 제2과정을 포함하는 것을 특징으로 하는 직교 코드쌍을 이용한 순방향링크에서의 데이타 전송속도 가변방법.The present invention relates to a method for varying a data transmission rate in a CDMA mobile communication system. In particular, an orthogonal code used to classify a subscriber's channel on the basis of an arbitrary transmission rate is increased by an amount of increasing the transmission data rate. And a second process of spreading transmission data using only one channel of a predetermined number of channels forming a pair of orthogonal codes allocated in the first process, and transmitting the spread data by using a pair unit. A method of varying data rates in a forward link using orthogonal code pairs.
