Abstract

본 발명은 가변 속도 전송 데이타의 부분 종속적 랜덤화 방법에 관한 것으로서, 800MHz 대역 CDMA 이동통신시스템에서 역방향 통화 채널의 새로운 데이타의 부분 종속적 랜덤화 방법에 관한 것이다.The present invention relates to a method for partially dependent randomizing of variable rate transmission data and a method for partially dependent randomizing of new data of an uplink communication channel in an 800 MHz band CDMA mobile communication system.

일반적으로, 데이타 랜덤화는 코드 반복에 의해서 발생된 우복 데이타를 전력 제어 그룹(PCG) 단위로 개폐하는 패턴을 전송 속도와 바로 이전 전력 제어 그룹에서 사용한 긴 코드의 마지막 14 비트를 이용해 결정한다.Generally, data randomization determines the pattern of opening and closing the wobble data generated by code repetition by power control group (PCG) using the transmission rate and the last 14 bits of the long code used in the immediately preceding power control group.

이를 위해 본 발명은 전송 속도의 가변에 따라 소정 갯수의 전력 제어 그룹(PCG) 단위의 데이타가 개구 PCG간의 고정 거리를 갖고서 전송되도록 하는 방법을 제공한다.To this end, the present invention provides a method for allowing data of a predetermined number of power control group (PCG) units to be transmitted with a fixed distance between open PCGs according to the variable transmission rate.

이와 같은 본 발명은 종래의 데이타 랜덤화 방법보다 전력 제어에 의한 역방향 채널 환경의 예측과 실제 환경과의 오차를 줄일 수가 있는 것이다.The present invention can reduce the error between the real environment and the prediction of the reverse channel environment by the power control over the conventional data randomizing method.
