Abstract: front page image
(EN)According to one aspect of the present invention, the present invention provides a method for allowing a base station, which receives signals from one or more terminals, to align receiving signals and interference signals in a wireless access system. Said method comprises the steps of: receiving the receiving signals and the interference signals, wherein said receiving signals are signals which are received from terminals that belong to a serving cell of said base station, and said interference signals are signals which are received from terminals that belong to neighbor cells of said base station; dividing a signal space for receiving said receiving signals and said interference signals into one or more signal spaces of size N; and arranging K receiving signals of said receiving signals in each of said divided signal spaces, wherein said K receiving signals arranged in each of said divided signal spaces are orthogonal to each other.
(FR)Selon un aspect de la présente invention, la présente invention a trait à un procédé permettant à une station de base, qui reçoit des signaux provenant d'un ou de plusieurs terminaux, d'aligner les signaux de réception et les signaux d'interférence dans un système d'accès sans fil. Ledit procédé comprend les étapes consistant : à recevoir les signaux de réception et les signaux d'interférence, lesquels signaux de réception sont des signaux qui sont reçus en provenance de terminaux qui appartiennent à une cellule de desserte de ladite station de base, et lesquels signaux d'interférence sont des signaux qui sont reçus en provenance de terminaux qui appartiennent à des cellules voisines de ladite station de base; à partager un espace de signaux permettant de recevoir lesdits signaux de réception et lesdits signaux d'interférence en un ou plusieurs espaces de signaux de taille N; et a agencer K signaux de réception desdits signaux de réception dans chacun desdits espaces de signaux partagés, lesquels K signaux de réception agencés dans chacun desdits espaces de signaux partagés étant orthogonaux les uns aux autres.
(KO)본 명세서의 일 개시에 따르면 무선 접속 시스템에서 하나 이상의 단말로부터 신호를 수신하는 기지국이 수신 신호와 간섭 신호를 정렬(alignment)하는 방법이 개시된다. 상기 방법은 수신 신호 및 간섭 신호를 수신하는 단계와, 상기 수신 신호는 상기 기지국의 서빙(serving) 셀에 속한 단말들로부터 수신하는 신호이고, 상기 간섭 신호는 상기 기지국의 이웃 셀에 속한 단말들로부터 수신하는 신호이며; 상기 수신 신호 및 상기 간섭 신호를 수신하는 신호 공간을 N의 크기를 갖는 하나 이상의 신호 공간으로 나누는 단계와; 상기 나누어진 각 신호 공간에 상기 수신 신호 중 K개의 수신 신호들을 배치하는 단계를 포함하되,상기 나누어진 각 신호 공간에 배치된 상기 K개의 수신 신호들은 서로 직교하는 것을 특징으로 한다.
