- 하이브리드 ARQ시스템에서 레이트매칭 알고리즘의 초기치를 재전송 횟수에 따라 가변시키는 단계를 포함하여 이루어지는 것을 특징으로 하는 하이브리드 ARQ시스템에서 레이트매칭 알고리즘의 초기치 설정방법.
- 제 1 항에 있어서, 상기 레이트매칭 알고리즘의 초기치를 재전송 횟수를 변수로 하는 함수의 값을 모듈러 연산을 통해 레이트매칭 알고리즘 초기치에 가산해 줌으로써 변화시키는 것을 특징으로 하는 하이브리드 ARQ시스템에서 레이트매칭 알고리즘의 초기치 설정방법.
- 제 1 항에 있어서, 상기 레이트매칭 알고리즘의 초기치를 재전송 횟수를 변수로 하는 함수의 값으로부터 변화시킬 때, 그 함수가 단순 증가하는 함수이거나, 혹은 비트 리버싱(비트 반전)을 이용해서 구성하는 것을 특징으로 하는 하이브리드 ARQ시스템에서 레이트매칭 알고리즘의 초기치 설정방법.
- 제 1 항에 있어서, 상기 레이트매칭 알고리즘의 초기치를 재전송 횟수를 변수로 하는 함수값으로부터 변화시켜 주는 단계가 하향링크나 상향링크에 적용되는 것을 특징으로 하는 하이브리드 ARQ시스템에서 레이트매칭 알고리즘의 초기치 설정방법.
- 하이브리드 ARQ 시스템에서 레이트매칭 알고리즘의 초기치를 재전송 횟수에 따라 가변시켜 주기 위하여, 모듈러 연산자 K를 정의하는 단계, 현재 펑처링 또는 반복인지의 여부를 판별하는 단계, 상기 판별 결과에 따라 초기치 조정을 위한 증분을 결정하는 단계, 상기 결정된 증분값에 따라 초기치를 재설정하는 단계로 이루어진 것을 특징으로 하는 하이브리드 ARQ시스템에서 레이트매칭 알고리즘의 초기치 설정방법.
