Abstract

Des modes de réalisation de la présente invention concernent un procédé d'envoi d'informations de capacité de réseau. Le procédé est appliqué à un dispositif de réseau d'accès, et consiste à : envoyer des informations de capacité de réseau à un terminal, les informations de capacité de réseau étant utilisées pour indiquer une plage de spectre de fréquences prise en charge par un réseau sur une bande de fréquences prédéterminée (étape 31). Ainsi, lors de la réception des informations de capacité de réseau, le terminal peut déterminer, sur la base de la plage de spectre de fréquences prise en charge par le réseau sur la bande de fréquences prédéterminée, si le terminal prend en charge une communication dans la plage de spectre de fréquences, ce qui permet de déterminer si une communication sans fil peut être effectuée sur la base du réseau, et par comparaison avec un mode dans lequel les informations de capacité de réseau ne peuvent pas être acquises, la plage de spectre de fréquences prise en charge par le réseau peut être indiquée de manière efficace et précise, et la scène selon laquelle la plage de spectre de fréquences prise en charge par le réseau est étendue en continu et peut être adaptée de manière flexible.
