Embodiments describe methods and nodes for configuring multiple links of a relay node in a communication system. Another node transmits a configuration signal toward the relay node including at least one bandwidth to be used to configure the multiple links of the relay. The at least one bandwidth can be the same for each of the multiple links or can be different for each of the multiple links. The multiple links can, for example, be the access link (i.e., the link via which user equipment communicates with the relay node over an air interface) and the backhaul link (i.e., the link via which the relay node communicates with the rest of the network, e.g., connected to a donor node).
