Abstract: front page image
(EN)The present invention relates to a method for a terminal to transmit channel state information in a multi-cell cooperative wireless communication system. Particularly, the method comprises the steps of: determining a precoding matrix index (PMI) for a serving cell from among a plurality of PMIs; structuring PMI information for a cooperative cell based on the PMI for the serving cell; and transmitting the PMI for the serving cell and the PMI information for the cooperative cell to the serving cell, wherein a plurality of the PMIs are divided into a plurality of PMI subsets, PMIs included by the respective PMI subsets are vertically placed, and the PMI information for the cooperative cell comprises a first indicator indicating one of a plurality of the PMI subsets to a PMI subset for the cooperative cell, and a second indicator indicating at least one of the PMIs in the indicated PMI subset to the PMI for the cooperative cell.
(FR)La présente invention concerne un procédé pour qu'un terminal transmette des informations d'état de canal dans un système de communication sans fil à cellules multiples coopératif. En particulier, le procédé comprend les étapes : de détermination d'un indice de matrice de précodage (PMI) pour une cellule desservante parmi une pluralité de PMI ; de structuration des informations de PMI pour une cellule coopérative sur la base du PMI pour la cellule desservante ; et de transmission du PMI pour la cellule desservante et des informations de PMI pour la cellule coopérative à la cellule desservante, une pluralité de PMI étant divisés en une pluralité de sous-ensembles de PMI, les PMI inclus dans les sous-ensembles de PMI respectifs étant placés verticalement, et les informations de PMI pour la cellule coopérative comprenant un premier indicateur indiquant l'un d'une pluralité des sous-ensembles de PMI pour un sous-ensemble de PMI pour la cellule coopérative, et un second indicateur indiquant au moins l'un des PMI dans le sous-ensemble de PMI indiqué pour le PMI pour la cellule coopérative.
(KO)본 출원에서는 다중 셀 협력 무선 통신 시스템에서 단말이 채널 상태 정보를 전송하는 방법이 개시된다. 구체적으로, 복수의 프리코딩 행렬 인덱스(PMI; Precoding Matrix Index)들 중 서빙 셀을 위한 PMI를 결정하는 단계; 상기 서빙 셀을 위한 PMI에 기반하여, 협력 셀을 위한 PMI 정보를 구성하는 단계; 및 상기 서빙 셀을 위한 PMI와 상기 협력 셀을 위한 PMI 정보를 상기 서빙 셀로 송신하는 단계를 포함하고, 상기 복수의 PMI들은. 복수의 PMI 서브셋으로 구분되고, 각각의 PMI 서브셋 내에 포함되는 PMI들은 서로 직교하며, 상기 협력 셀을 위한 PMI 정보는 상기 복수의 PMI 서브셋들 중 하나를 상기 협력 셀을 위한 PMI 서브셋으로 지시하는 제 1 지시자, 및 상기 지시된 PMI 서브셋 내의 PMI들 중 적어도 하나를 상기 협력 셀을 위한 PMI로 지시하는 제 2 지시자를 포함하는 것을 특징으로 한다.
