Abstract: A method for donor selection in a relay access node includes identifying a plurality of candidate donor access nodes and obtaining one or more characteristics associated with each of the plurality of candidate donor access nodes. The method further includes determining a primary donor access node based on a comparison of the one or more characteristics between each of the plurality of candidate donor access nodes, and receiving a reference signal transmitted by the primary donor access node at a transmission power higher than a transmission power of downlink information transmitted by the primary donor access node. One or more quality characteristics of the primary donor access node are evaluated, and based on the one or more quality characteristics meeting a predetermined threshold, a connection to the primary donor access node is requested. Devices and systems relate to donor selection.
