Abstract:
(EN) The present invention relates to a method and an apparatus for link scheduling comprising the steps of: searching device-to-device (D2D) pairs capable of a D2D communication; obtaining channel coefficient information of each of the searched D2D pairs; sorting the searched D2D pairs in descending order using the channel coefficient; calculating a sum rate when a k-th D2D pair in the sorted order of the searched D2D pairs is added; comparing the sum rate with a sum rate when a k-1-th D2D pair is added; and selecting D2D pairs which can maximize the sum rate, considering the comparison result.
(FR) La présente invention concerne un procédé et un appareil de programmation de liaison comprenant les étapes qui consistent à : rechercher des paires dispositif à dispositif (D2D) pouvant établir une communication D2D; obtenir des informations de coefficient de canal de chacune des paires D2D recherchées; trier les paires D2D recherchées dans l'ordre décroissant au moyen du coefficient de canal; calculer le débit total lors de l'ajout d'une k-ième paire D2D dans l'ordre trié des paires D2D recherchées; comparer le débit total au débit total lorsqu'une k-1ème paire D2D est ajoutée; et sélectionner les paires D2D pouvant maximiser le débit total, compte tenu du résultat de la comparaison.
(KO) 본 발명은 D2D 통신이 가능한 D2D 페어들을 검색하고, 상기 검색된 D2D 페어들 각각의 채널 계수 정보를 획득하고, 상기 채널 계수를 이용해서 상기 검색된 D2D 페어들을 내림차순으로 정렬하고, 검색된 D2D 페어들을 정렬된 순서대로 k번째 D2D 페어가 추가된 경우의 전송 용량의 합(sum rate)을 계산하고, k-1번째 D2D 페어가 추가된 경우의 전송 용량의 합과 비교하고, 비교결과를 고려하여 전송 용량의 합(sum rate)이 최대가 될 수 있는 D2D 페어들을 선택하는 링크 스케줄링 방법 및 장치에 관한 것 이다.
