Title: Allocation Method of data rate in the reverse link
Inventor: LEE YEONG JO
IPC: H04B7/26
Filed: 2001-02-10
Abstract: PURPOSE: A method for allocating the transfer speed of reverse link data is provided so that a mobile station can transmit data at a data rate and a data transmission time allocated according to the receive power status or interference level of a base station as the base station receives the maximum date rate of the mobile station, judges available total receive power according to load information, and allocates the data rate and the data transmission time to the mobile station. CONSTITUTION: The base station(210) periodically controls the power of a mobile station(220) in its own control area(S201). In case that the mobile station tries to transmit data through a reverse link, the mobile station determines the maximum data rate using available power and transmits it to the base station(S202). Receiving the maximum data rate, the base station measures the total interference level with other mobile stations and base stations and allocates an available date rate and a transmission time to the mobile station(S203). The mobile station transmits data at the allocated date rate within the allocated transmission time(S204).

IPC: H03L7/183
Filed: 2001-05-02
Abstract: 본 발명은 PLL 회로에 의하여 주파수를 발생시키는 방법에 관한 것이다. 
     종래의 PLL 회로에 있어서는, 원하는 주파수로 트랜션트 오실레이션(transient oscillation)을 가속하기 위하여 페이저 검출기의 출력 신호는 변화한다. 
     상기 방법에 있어서, 페이저 검출기에 공급되는 2개의 비교 주파수는 적어도 하나 이상의 스위치를 통해서 인자(factor)들에 의해 동시에 변화한다.  대략의 조정을 위하여, 비교 주파수는 튜닝 과정을 가속시키는 인자에 의해 증가한다.  그러므로, 증가된 비교 주파수는 증가량(increment)을 결정하는 미세 튜닝을 위한 인자에 의해 다시 감소한다. 
     주파수 튜닝 PLL 회로에 대한 방법은, 예컨대 라디오 디바이스에서 RDS 장치와 같이 주파수 변화가 빨리 그리고 청취되지 않게 일어나는 곳에서 사용되고, 여기서 장점을 가진다.
