Title
(EN) DETERMINING CHANNEL STATE INFORMATION IN MULTI-TRANSMISSION RECEPTION POINT SYSTEMS
(FR) DÉTERMINATION D'INFORMATIONS D'ÉTAT DE CANAL DANS DES SYSTÈMES À POINTS D'ÉMISSION ET RÉCEPTION MULTIPLES
Abstract
(EN) Methods, apparatuses, and systems for determining the measurement of reference signals in a wireless system are described. In one aspect, a wireless communication method is disclosed. The method includes determining measurement reference signal information based on transmission configuration indication (TCI) codepoint information, wherein the TCI codepoint information is indicated in a TCI field in a physical downlink control channel (PDCCH), wherein the reference signal measurement information includes a TCI codepoint index. The method further includes determining a measurement reference signal resource in a measurement reference signal resource set according the TCI codepoint index, and measuring the reference signal.
(FR) La présente invention concerne des procédés, des appareils et systèmes permettant de déterminer la mesure de signaux de référence dans un système sans fil. Selon un aspect, la présente invention concerne un procédé de communication sans fil. Le procédé consiste à déterminer des informations de signal de référence de mesure d'après des informations de points de code d'une indication de configuration de transmission (TCI), les informations de points de code TCI étant indiquées dans un champ TCI dans un canal de commande de liaison descendante physique (PDCCH), et les informations de mesure de signal de référence comprenant un indice de points de code TCI. Le procédé consiste également à déterminer une ressource de signal de référence de mesure dans un ensemble de ressources de signal de référence de mesure en fonction de l'indice de points de code TCI, ainsi qu'à mesurer le signal de référence.
