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 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.
