Title (EN) CHANNEL STATE INFORMATION FEEDBACK METHOD AND USER EQUIPMENT
(FR) PROCÉDÉ DE RENVOI D'INFORMATIONS D'ÉTAT DE CANAL ET ÉQUIPEMENT UTILISATEUR
Abstract: front page image
(EN)A Channel State Information (CSI) feedback method and a User Equipment (UE) are disclosed. The method comprises the following steps of: determining a set of coordinated Base Stations (BSs) participating multi-BS coordination, the set of coordination BSs containing a serving BS and at least one non-serving BS; for each BS in the set of coordinated BSs: calculating a Signal to Interference and Noise Ratio (SINR) for a channel between a UE and the BS based on a hypothetical BS coordination mode corresponding to the BS; and deriving a Channel Quality Index (CQI) corresponding to the calculated SINR and feeding back the derived CQI to the serving BS.
(FR)L'invention porte sur un procédé de renvoi d'informations d'état de canal (CSI) et sur un équipement utilisateur (UE). Le procédé comporte les étapes suivantes consistant à : déterminer un ensemble de stations de base (BS) coordonnées participant à une coordination de multiples BS, l'ensemble de BS coordonnées contenant une BS de desserte et au moins une BS non de desserte ; pour chaque BS dans l'ensemble de BS coordonnées : calculer un rapport signal sur brouillage plus bruit (SINR) pour un canal entre un UE et la BS sur la base d'un mode de coordination de BS hypothétique correspondant à la BS ; obtenir un indice de qualité de canal (CQI) correspondant au SINR calculé et renvoyer le CQI obtenu à la BS de desserte.
