Abstract:
(EN) A method for a terminal, in a wireless communication system, receiving a downlink signal from a cell in which a plurality of beams are multiplexed according to an embodiment of the present invention comprises the steps of: generating a quasi-orthogonal scrambling sequence that is used for scrambling the downlink signal; and receiving the downlink signal through one or more beams of the plurality of multiplexed beams using the generated quasi-orthogonal scrambling sequence, wherein the terminal can initialise the quasi-orthogonal scrambling sequence using a beam-specific parameter corresponding to one or more beams for transmitting the downlink signal when generating the quasi-orthogonal scrambling sequence.
(FR) Selon un mode de réalisation, l'invention concerne un procédé pour qu'un terminal, dans un système de communication sans fil, reçoive un signal de liaison descendante provenant d'une cellule dans laquelle une pluralité de faisceaux sont multiplexés, lequel comprend les étapes consistant à: générer une séquence de brouillage quasi-orthogonal qui est utilisée pour brouiller le signal de liaison descendante; et recevoir le signal de liaison descendante par l'intermédiaire d'un ou de plusieurs faisceaux de la pluralité de faisceaux multiplexés à l'aide de la séquence de brouillage quasi-orthogonal générée, le terminal pouvant initialiser la séquence de brouillage quasi-orthogonal à l'aide d'un paramètre spécifique au faisceau correspondant à un ou plusieurs faisceaux pour transmettre le signal de liaison descendante lors de la génération de la séquence de brouillage quasi-orthogonal.
(KO) 본 발명의 일 실시예에 따른 무선 통신 시스템에서의 단말이 다수의 빔(beam)들이 다중화된 셀(cell)로부터 하향링크 신호를 수신하는 방법은, 상기 하향링크 신호의 스크램블링(scrambling)을 위해 사용된 유사-직교 스크램블링 시퀀스(quasi-orthogonal scrambling sequence)를 생성하는 단계; 및 상기 생성된 유사-직교 스크램블링 시퀀스를 이용하여, 상기 다중화된 다수의 빔들 중 적어도 하나의 빔을 통해 상기 하향링크 신호를 수신하는 단계를 포함하고, 상기 단말은 상기 유사-직교 스크램블링 시퀀스를 생성함에 있어서, 상기 하향링크 신호를 송신하는 적어도 하나의 빔에 대응하는 빔-특정 파라미터를 이용하여 상기 유사-직교 스크램블링 시퀀스를 초기화할 수 있다.
