Abstract
(EN)
Methods, systems, and devices for wireless communications are described. A wireless device (e.g., a user equipment and/or base station) (405) may operate in a first mode in a wireless network over a radio frequency spectrum band (415). The wireless device (405) may receive a signal indicating that a value of the radio frequency spectrum band has satisfied a threshold value (420). The wireless device may switch, based at least in part on the signal indicating that the value has satisfied the threshold value, from the first mode to a second mode for wireless communications in the wireless network (425), wherein a first length of a first synchronization signal block associated with the first mode is shorter than a second length of a second synchronization signal block associated with the second mode.

L’invention concerne des procédés, des systèmes et des dispositifs de communications sans fil. Un dispositif sans fil (par exemple, un équipement d'utilisateur et/ou une station de base) (405) peut être mis en œuvre dans un premier mode dans un réseau sans fil sur une bande de spectre radiofréquence (415). Le dispositif sans fil (405) peut recevoir un signal indiquant qu'une valeur de la bande de spectre radiofréquence a satisfait une valeur seuil (420). Le dispositif sans fil peut passer, sur la base, au moins en partie, du signal indiquant que la valeur a satisfait la valeur seuil, du premier mode à un second mode de communications sans fil dans le réseau sans fil (425), une première longueur d'un premier bloc de signaux de synchronisation associé au premier mode étant plus courte qu'une seconde longueur d'un second bloc de signaux de synchronisation associé au second mode.
