Abstract: front page image
(EN)A method for terminal clustering in a wireless communication system which supports device-to-device communication and an apparatus therefor are disclosed. Particularly, a method for performing terminal clustering by a terminal in a wireless communication system which supports device-to-device (D2D) communication may comprise the steps of: determining an initial preference value; determining an initial preference triplet by performing an affinity propagation (AP) technique while increasing or decreasing the initial preference value; updating the preference triplet through a golden section search (GSS) technique on the basis of the initial preference triplet; determining, from the updated preference triplet, a final preference value for minimizing the energy consumption of all terminals; and determining a head terminal and member terminals belonging to the head terminal by performing the AP technique using the final preference value.
(FR)L'invention a trait à un procédé de mise en grappe de terminaux dans un système de communication sans fil qui prend en charge la communication de dispositif à dispositif, ainsi qu'à un appareil associé. En particulier, un procédé de mise en grappe de terminaux par un terminal dans un système de communication sans fil qui prend en charge la communication de dispositif à dispositif (D2D), peut comprendre les étapes consistant : à déterminer une valeur de préférence initiale; à déterminer un triplet de préférence initial grâce à la mise en œuvre d'une technique de propagation d'affinité (AP) pendant que la valeur de préférence initiale augmente ou diminue; à mettre à jour le triplet de préférence par la méthode du nombre d'or (GSS) sur la base du triplet de préférence initial; à déterminer, à partir du triplet de préférence mis à jour, une valeur de préférence finale permettant de réduire au minimum la consommation d'énergie de tous les terminaux; et à déterminer un terminal principal et des terminaux membres appartenant au terminal principal grâce à la mise en œuvre de la technique AP au moyen de la valeur de préférence finale.
(KO)단말 간 통신을 지원하는 무선 통신 시스템에서 단말 클러스터링을 위한 방법 및 이를 위한 장치가 개시된다. 구체적으로, D2D(Device-to-Device) 통신을 지원하는 무선 통신 시스템에서 단말이 단말 클러스터링(clustering)을 수행하기 위한 방법에 있어서, 선호도(preference) 초기 값을 결정하는 단계, 상기 선호도 값을 증가 또는 감소시키면서 친밀도 확산(AP: Affinity Propagation) 기법을 수행함으로써, 초기 선호도 트리플렛(triplet)을 결정하는 단계, 상기 초기 선호도 트리플렛을 기반으로 황금 분할 탐색(GSS: Golden Section Search) 기법을 통해 선호도 트리플렛을 업데이트하는 단계, 상기 업데이트 된 선호도 트리플렛으로부터 전체 단말의 에너지 소모를 최소화하기 위한 최종 선호도 값을 결정하는 단계 및 상기 최종 선호도 값을 이용하여 상기 AP 기법을 수행함으로써, 헤드 단말 및 상기 헤드 단말에 속하는 멤버 단말을 결정하는 단계를 포함할 수 있다.
