The mobile relay node may determine the mobility state itself or based on received information from another network node. Control information is determined based on the determined mobility state of the mobile relay node and an action is then performed or initiated based on the determined control information. The tree different mobility states may include moving, standing, and at least one additional mobility state. Example additional mobility states of the mobile radio node include: departing, arriving, or temporarily stopped. ## Claims ### Claim at position 1 1-58.
