Abstract
(EN)
Disclosed in embodiments of the present application are a method for sampling a self-interference signal, a terminal device, and a network device. The method comprises: the terminal device receives configuration information sent by the network device, the configuration information being used for indicating a sampling timeslot of an uplink signal, no downlink signal existing in the sampling timeslot, the uplink signal being capable of generating self-interference on the downlink signal, and subcarrier spacings of the uplink signal and the downlink signal being different. The method, the terminal device, and the network device in the embodiments of the present application facilitate sampling a clean self-interference signal, so as to reach perfect self-interference cancellation.

Des modes de réalisation de la présente invention concernent un procédé d'échantillonnage d'un signal d'auto-brouillage, un dispositif terminal et un dispositif de réseau. Le procédé comprend : la réception par le dispositif terminal d'informations de configuration envoyées par le dispositif de réseau, les informations de configuration étant utilisées pour indiquer un intervalle temporel d'échantillonnage d'un signal de liaison montante, aucun signal de liaison descendante n'existant dans l'intervalle temporel d'échantillonnage, le signal de liaison montante étant capable de générer un auto-brouillage sur le signal de liaison descendante, et des espacements de sous-porteuses du signal de liaison montante et du signal de liaison descendante étant différents. Le procédé, le dispositif terminal et le dispositif de réseau dans les modes de réalisation de la présente invention facilitent l'échantillonnage d'un signal d'auto-brouillage propre, de façon à atteindre une annulation d'auto-brouillage parfaite.
