Abstract: 본 발명은 다차원 도약 패턴 충돌시 충돌 구간에서의 송신 제어 방법 및 장치에 관한 것이다. 본 발명에서는 주어진 직교 무선 자원을 송신측 및 수신측 사이의 통신 규약에 의하여 다차원 직교 자원 영역에서 도약 선택하며, 해당 채널은 다차원 도약 패턴에 의하여 구별된다. 이때, 제2 통신국별로 특정한 다차원 도약 패턴을 할당하고, 다차원 도약 패턴은 제2 통신국에 영구적으로 할당될 수도 있고, 호설정시에 제1 통신국으로부터 할당받을 수도 있다. 또한, 다차원 직교 자원 도약 패턴이 각 제2 통신국에게 영구적으로 할당되는 것은 제2 통신국의 ESN(Electronic Serial Number) 등과 같이 유일한 식별자를 바탕으로 다차원 도약 패턴이 정해질 때이다. 이런 경우, 제2 통신국의 다차원 도약 패턴이 서로 독립이기 때문에 특정 순간에 동일한 직교 자원 좌표가 서로 다른 제2 통신국에 동시에 할당될 수 있다. 본 발명에 따르면, 다차원 직교 자원 도약 다중화 방식을 채택한 시스템의 성능을 향상시키기 위하여 전송과 천공의 2분법적으로 이루어지는 다차원 직교 자원 도약 패턴 충돌시 처리 방법을 세분화함으로써 천공의 경우를 줄일 수 있다.

Abstract: PURPOSE: A digital communication method is provided to subdivide a processing method when hopping patterns of multidimensional orthogonal resources collide with each other, thereby reducing perforation and improving performance of a system adopting a hopping multiplex system thereinto. CONSTITUTION: When hopping patterns of multidimensional orthogonal resources collide with each other, a system controls transmission signals of each orthogonal wireless resource unit according to transmission data symbols associated with the collision and transmission signal amplitudes of communication channels. The system decides codes of data symbols transmitted in orthogonal wireless resource unit of the communication channels where the hopping patterns collide with each other. The system divides the data symbols into a channel set that is not transmitted in the orthogonal wireless resource unit, a channel set in which the data symbols are positive numbers, and a channel set in which the data symbols are negative numbers, then determines the data symbols transmitted in the orthogonal wireless resource unit.

Abstract: PURPOSE: A method for assigning a transmission antenna beam pattern according to the state of a downlink common physical channel in a mobile communication system is provided to efficiently assign an antenna beam pattern according to the characteristic of the downlink common physical channel. CONSTITUTION: A base station judges the characteristic of a downlink common physical channel signal when transmitting the downlink common physical channel signal to an MS(Mobile Station) which exists in a sectored cell area. If a downlink common physical channel has a characteristic for transmitting information applied to all MSs which exist in the cell area, the base station applies the downlink common physical channel signal to an omni-directional antenna beam pattern and transmits the downlink common physical channel signal.

Abstract: PURPOSE: A transmit-receive method and apparatus using spreading modulation in a band spreading communication system is provided to improve the deterioration of a PAR(Peak-to-Average Ratio) characteristic, due to transition to the origin, by making the transition-to-origin probability of a descrambling signal(xT(n) + jyT(n)) into '0' in all visual angles but a visual angle n=0 (mod min{SFPiCH, SFDCCH, SFSCH2, SFSCH1, SFFCH}). CONSTITUTION: Taking the transfer data of SCH#1 and SCH#2 as the first input and OVSF(Orthogonal Variable Spreading Factor) codes(HSCH1(n),HSCH2(n)) as the second input, the first complex multiplier(142) executes a primary orthogonal complex spreading. The output of the first complex multiplier(142) and the PiCH, DCCH and FCH spread by HPiCH(n), HDCCH(n) and HFCH(n) are inputted to adders(130,132). A spreading modulator(141) generates and outputs IT(n) and QT(n), taking the outputs(xT(n),yT(n)) of the adders(130,132) as the first input and primary scrambling codes(C1(n),C1(n)) as the second input. The spreading modulator(141) is composed of a scrambling code generator(520) and the first complex multiplier(142). The scrambling code generator(520), receiving the primary scrambling codes(C1(n),C1(n)), generates secondary scrambling codes(Cscramble,I(n),Cscramble,Q(n)).
