Filed: 1999-02-10
Abstract: 무선 통신 시스템이 수신 주파수 합성을 제공하기 위해 다중 반송파 상에서 동시에 데이타를 송신한다.  반송파 간섭은 다중 반송파들의 상대 위상이 제로일 때 시간 영역에 대해 좁은 폭을 갖는 펄스를 일으킨다.  주파수 간격 및 반송파 위상의 선택은 펄스 타이밍을 제어한다.  펄스의 시간 분할과 반송파의 주파수 분할 양자가 다중 접속를 성취한다.   주파수 간섭은 다른 통신 프로토콜이 도출될 수 있는 기초가 된다.  반송파의 주파수 호핑 및 주파수 변이는 반송파들 사이의 상대적인 간격 및 위상이 보존된다면 펄스 포락선을 변화시키지 않는다.  직접 시퀀스  CDMA 신호가 반송파 진폭을 미리 결정해 선택함으로써 시간 영역에 대해서 생성된다.  각각의 펄스는 다른 시간에 다른 위상 공간에서  샘플될 수 있다.  이는 종래의 수신기에 의해서 검출되지 않는 위상 공간에서의 통신을 가능케 해 준다.  반송파의 시간 의존 위상 관계는 안테나 어레이에 위해 송신되는 빔 패턴을 자동을 스캔하게 하여 준다.  도파관 통신에서 반송 주파수 및 위상 공간은 광 섬유의 색 분산과 정합되어 광 섬유의 용량을 증가시킨다.

Title: Handoff controlling method for mobile communication system
Inventor: HWANG SEUNG HUN
IPC: H04B7/26
Filed: 2001-01-16
Abstract: PURPOSE: A handoff method in an up-link synchronous transmission system is provided to separately consider only a hard handoff owing to an increase in a cell occupancy region as well as a performance and an accommodation capacity by allowing a base station to select a timing to be hard handoff to a base station which a mobile station takes as a reference timing and transmitting a control bit to the base station. CONSTITUTION: When a mobile station advances into a handoff region(301), the mobile station measures strengths of pilots of the current base station and a target base station(302) and determines whether the measured pilot strength of the target base station is sufficient(303). If the pilot strength of the target base station, the target base station receives a handoff instruction message from a base station controller and performs a handoff(304,305). The mobile station forms a link between the current base station and the target base station, and the base station controller measures/compares a quality of the mobile station signal of both links to determine whether a timing adjustment and a reconfiguration are required the state of the target base station and determine whether to perform handoff(307). If the adjustment and reconfiguration are required with the synchronous timing of the target base station, a timing hard handoff message is transmitted for synchronization in the target base station and timing adjustment and reconfiguration are re-set to perform a synchronous timing hard handoff(308). The current base station resets codes by the handoff message from the base station controller and communicates with the codes used in the target base station(309). The mobile station measures a strength of a pilot 'A' of the current base station to determine whether the measured value is sufficient(311). When the measure time reaches a handoff banishing timer limit value, the mobile station transmits a pilot strength measurement message and receives a handoff instruction from the base station controller(312). The mobile station excludes the pilot 'A' from an actual call list and transmits a handoff completion message, thereby completing a handoff process(313).
