Abstract
A network node is configured with a common preamble format for a shared spectrum comprising a first Radio Access Technology (RAT) and a second RAT. The RACH procedure is common for the first and second RAT. The network node configures the network node with a common preamble location in time and frequency for the first and second RAT. The network node configures the UE with a preamble group comprising a number of preambles distributed between the first and second RAT for the common preamble format. When receiving from the UE, a first RACH message comprising a first preamble at the common preamble location according to the UE configuring, the network node decides whether the first RAT, the second RAT, or both the first and second RAT, shall be used for a second RACH message to be sent to the UE.
