Abstract:
(EN) Methods, systems, and devices for wireless communication are described. Generally, the described techniques provide for communicating an uplink grant and a channel state information reference signal (CSI-RS) trigger. A wireless device may identify a pending collision for a slot of a carrier between a CSI-RS and uplink data. The wireless device may determine a communication configuration for the CSI-RS and the uplink data such that no collision occurs. The determined communication configuration for the CSI-RS may include delaying one of the colliding signals, transmitting only one of the colliding signals and suppressing the other, or reconfiguring the slot such that both signals can be transmitted successfully. Additionally, the UE and the base station may determine a CSI reporting configuration based on the determined communication configuration.
(FR) L'invention concerne des procédés, des systèmes et des dispositifs de communication sans fil. D'une manière générale, les techniques décrites permettent de communiquer une autorisation de liaison montante et un déclencheur de signal de référence d'informations d'état de canal (CSI-RS). Un dispositif sans fil peut identifier une collision en attente pour un créneau d'une porteuse entre un CSI-RS et des données de liaison montante. Le dispositif sans fil peut déterminer une configuration de communication pour le CSI-RS et les données de liaison montante de telle sorte qu'aucune collision ne se produise. La configuration de communication déterminée pour le CSI-RS peut comprendre le retardement de l'un des signaux de collision, la transmission d'un seul des signaux de collision et la suppression de l'autre, ou la reconfiguration du créneau de telle sorte que les deux signaux puissent être transmis avec succès. De plus, l'UE et la station de base peuvent déterminer une configuration de rapport de CSI sur la base de la configuration de communication déterminée.
