摘要： Embodiments of this application disclose a channel characteristic obtaining method and a related apparatus. The method includes: A first communication apparatus sends a first reference signal and a first notification message to a second communication apparatus; and the first communication apparatus receives channel characteristic information of a first channel type from the second communication apparatus. The first channel type is a channel type corresponding to first channel state information CSI determined by the second communication apparatus based on the first reference signal, the first notification message is used to request the channel characteristic information of the first channel type, a channel characteristic of the first channel type is from a channel characteristic library, and the channel characteristic library includes channel characteristics of one or more channel types. In this way, the first communication apparatus obtains the channel characteristic of the first channel type based on the channel characteristic information of the first channel type. This helps the first communication apparatus perform channel reconstruction, estimation, or the like based on the channel characteristic of the first channel type, to improve performance of communication between the first communication apparatus and the second communication apparatus.

摘要： L'invention concerne un procédé d'estimation de paramètres caractéristiques d'une qualité de réception en une localisation d'un réseau de radiocommunication cellulaire. Ce procédé comprend:
- une sélection parmi un ensemble de cellules du réseau, d'au moins deux cellules offrant des puissances moyennes de réception d'un signal utile à la localisation les plus élevées ;
- une détermination, à l'échelle logarithmique, d'au moins deux rapports signal sur interférence plus bruit à la localisation pour le signal utile reçu en provenance de chacune desdites au moins deux cellules sélectionnées ;
- une détermination d'un coefficient de corrélation entre lesdits au moins deux rapports signal sur interférence plus bruit déterminés à l'échelle logarithmique,
- une détermination d'un maximum entre lesdits au moins deux rapports signal sur interférence plus bruit déterminés à l'échelle logarithmique;
- une estimation des paramètres caractéristiques d'une qualité de réception à ladite localisation à partir dudit maximum et dudit coefficient de corrélation.
