Title
(EN) METHOD AND APPARATUS FOR COMMUNICATIONS IN A DISTRIBUTED ANTENNA SYSTEM
(FR) PROCÉDÉ ET APPAREIL POUR DES COMMUNICATIONS DANS UN SYSTÈME D'ANTENNES DISTRIBUÉES
Abstract
(EN) The disclosure relates to a 5G or 6G communication system for supporting a higher data transmission rate. A method performed by a user equipment (UE) in a wireless communication system is provided. The method includes receiving a first configuration for measuring a channel difference between a target cell and a reference cell in a cell group, receiving information for one or more measurement reference signals (RSs) to measure for determining the channel difference, receiving a second configuration for reporting the channel difference between the target cell and the reference cell in the cell group, measuring, based on the information, the measurement RSs, determining, based on the measured measurement RSs, the channel difference between the target cell and the reference cell in the cell group, and transmitting, based on the second configuration, a channel difference report associated with the determined channel difference. The measurement RSs comprise channel state information reference signals (CSI-RSs), synchronization signal blocks (SSBs), or both CSI-RSs and SSBs.
(FR) La divulgation concerne un système de communication 5G ou 6G pour prendre en charge un débit de transmission de données plus élevé. L'invention concerne un procédé mis en œuvre par un équipement utilisateur (UE) dans un système de communication sans fil. Le procédé comprend la réception d'une première configuration pour mesurer une différence de canal entre une cellule cible et une cellule de référence dans un groupe de cellules, la réception d'informations pour un ou plusieurs signaux de référence (RS) de mesure à mesurer pour déterminer la différence de canal, la réception d'une seconde configuration pour rapporter la différence de canal entre la cellule cible et la cellule de référence dans le groupe de cellules, la mesure, sur la base des informations, des RS de mesure, la détermination, sur la base des RS de mesure mesurés, de la différence de canal entre la cellule cible et la cellule de référence dans le groupe de cellules, et la transmission, sur la base de la seconde configuration, d'un rapport de différence de canal associé à la différence de canal déterminée. Les RS de mesure comprennent des signaux de référence d'informations d'état de canal (CSI-RS), des blocs de signal de synchronisation (SSB), ou à la fois des CSI-RS et des SSB.
