Title (EN) SWITCHING OF BANDWIDTH PARTS IN WIRELESS COMMUNICATION NETWORK
(FR) COMMUTATION DE PARTIES DE BANDE PASSANTE DANS UN RÉSEAU DE COMMUNICATION SANS FIL
Abstract:
(EN) The present disclosure relates to switching of bandwidth parts in wireless communication network. Embodiments may provide a method performed by a wireless device for switching of bandwidth parts. The method comprises: receiving (1501) a first message from a base station indicating a first physical uplink control channel; receiving (1502) a second message from the base station indicating switching from a first bandwidth part to a second bandwidth part; in response to the second message, switching (1504) to the second bandwidth part for communication with the base station, with a utilization of the first physical uplink control channel. A radio resource, such as a physical uplink control channel may be allocated previously to the wireless device, thus, service interruptions for the wireless device during the switch of bandwidth part may be reduced.
(FR) La présente invention concerne la commutation de parties de bande passante dans un réseau de communication sans fil. Des modes de réalisation peuvent porter sur procédé mis en œuvre par un dispositif sans fil pour la commutation de parties de bande passante. Le procédé comprend : la réception (1501) d'un premier message provenant d'une station de base indiquant un premier canal de commande de liaison montante physique; la réception (1502) d'un second message provenant de la station de base indiquant la commutation d'une première partie de bande passante (BWP) à une seconde partie de bande passante; en réponse au second message, la commutation (1504) vers la seconde partie de bande passante pour une communication avec la station de base, avec utilisation du premier canal de commande de liaison montante physique. Une ressource radio, telle qu'un canal de commande de liaison montante physique, peut être attribuée préalablement au dispositif sans fil, ce qui permet de réduire les interruptions de service pour le dispositif sans fil pendant la commutation de la partie de bande passante.
