Abstract

Des modes de réalisation de la présente demande concernent un procédé d'activation d'une BWP et un appareil de communication. Le procédé consiste à : recevoir des informations de configuration en provenance d'un dispositif de réseau d'accès, les informations de configuration comprenant une période d'activation et une durée d'activation d'une BWP ; et activer périodiquement la BWP en fonction de la période d'activation et de la durée d'activation de la BWP, la période d'activation étant utilisée pour indiquer un intervalle de temps entre deux activations adjacentes de la BWP, et la durée d'activation étant utilisée pour indiquer une durée lorsque la BWP maintient un état activé après avoir été activée. Sur la base de la solution, un équipement terminal peut activer périodiquement une BWP sur la base d'une période d'activation et d'une durée d'activation de la BWP configurée, de manière à mettre en œuvre une commutation automatique de la BWP, à réduire l'indication de commutation de la BWP par un dispositif de réseau d'accès au moyen d'une signalisation, et à réduire le traitement de la signalisation par l'équipement terminal. Par conséquent, le procédé peut réduire le surdébit d'interface radio pendant la commutation de la BWP et réduire la consommation d'énergie de l'équipement terminal.
