Abstract: front page image
(EN)Disclosed are a method, an apparatus, and a recording medium for scheduling users on the basis of a two-stage beamformer for a massive MIMO downlink. The method of the present invention comprises the steps of: setting variable i as a predetermined number and dividing groups of users until variable i is equal to independent data stream number Sg; whenever the step for dividing groups of users is repeated, updating variable i to i+1 and if variable i becomes greater than independent data stream number Sg, initializing variable i to the predetermined number; scheduling until the initialized variable i is equal to the independent data stream number Sg; and whenever the scheduling step is repeated, updating variable i to i +1.
(FR)L'invention concerne un procédé, un appareil et un support d'enregistrement pour la planification d'utilisateurs sur la base d'un dispositif de formation de faisceau à deux étages pour une liaison descendante MIMO massif. Le procédé de la présente invention comprend les étapes consistant : à régler une variable i à un nombre prédéterminé et diviser des groupes d'utilisateurs jusqu'à ce que la variable i soit égale à un nombre de flux de données indépendants Sg ; chaque fois que l'étape de division de groupes d'utilisateurs est répétée, à mettre à jour la variable i à i+1 et si la variable i devient supérieure au nombre de flux de données indépendants Sg, initialiser la variable i au nombre prédéterminé ; à effectuer une planification jusqu'à ce que la variable initialisée i soit égale au nombre de flux de données indépendants Sg ; et chaque fois que l'étape de planification est répétée, à mettre à jour la variable i à i+1.
(KO)Massive MIMO 하향링크를 위한 두 단계 빔포머 기반의 사용자 스케줄링 방법, 장치 및 기록매체를 개시된다. 변수 _를 기설정된 숫자로 설정하고, 변수 _가 독립적인 데이터 스트림 수 _와 같아질 때까지 사용자들의 집합을 분할하는 단계, 사용자들의 집합을 분할하는 단계가 반복될 때마다 변수 _는 _로 업데이트하고, 변수 _가 독립적인 데이터 스트림 수 _보다 커지면, 변수는 상기 기설정된 숫자로 초기화하는 단계, 초기화된 변수 _가 상기 독립적인 데이터 스트림 수 _와 같아질 때까지 스케줄링하는 단계 및 스케줄링하는 단계가 반복될 때마다 변수 _는 _로 업데이트하는 단계를 포함한다.
