Abstract
(EN) A method, system, network node and wireless device are disclosed. In one or more embodiments, A network node configured to communicate with a wireless device is provided. The network node includes processing circuitry configured to transmit a first configuration for prioritized 2-step random access, RA, signaling 5 where the first configuration includes at least a power ramping step and is separately configured from a second configuration for RA signaling, and perform the prioritized 2-step RA signaling based on the power ramping step of the first configuration.
(FR) L'invention concerne un procédé, un système, un nœud de réseau et un dispositif sans fil. Selon un ou plusieurs modes de réalisation, l'invention concerne un nœud de réseau configuré pour communiquer avec un dispositif sans fil. Le noeud de réseau comprend un circuit de traitement configuré pour transmettre une première configuration pour une signalisation 5 d'accès aléatoire, RA, en deux étapes priorisée, la première configuration comprenant au moins une étape d'augmentation de puissance et étant configurée séparément à partir d'une seconde configuration pour une signalisation RA, et effectuer la signalisation RA en deux étapes priorisée sur la base de l'étape de variation de puissance de la première configuration.
