Abstract
A method and arrangement in a first node (101) for determining radio characteristics of a radio link between a first repeater (103, 203) and at least one second repeater (104, 204) are provided. The first node sends a first message, to the first repeater (103, 203), instructing the first repeater (103, 203) to send a radio signal being measureable by the second repeater (104, 204). Furthermore, the first node sends a second message, to said at least one second repeater, instructing said at least one second repeater (104, 204) to measure on the radio signal. The first node receives measurement data of the radio signal, measured by said at least one second repeater (104, 204). The first node (101) determines radio characteristics of the radio link between the first repeater (103, 203) and said at least one second repeater based on the measurement data. Methods and arrangements in a first and second repeater and a method and arrangement in a second node for contributing to radio characteristics determination are provided.
