An out-of-band relay node (800) reports its composite operating band capability to a donor base station or to another network node. The reported information indicates frequency band support separately for each of the backhaul and access links, which may operate over different frequency bands. In some embodiments, a controlling network node (700) such as a donor base station, an O&M node, an OSS node, a SON node, or another relay node, requests the relay node to report its backhaul link and access link operating frequency band capabilities to the network node. A network node (700) that receives the frequency capability information may use the information to select appropriate frequency bands for access and backhaul link operation and to configure the relay node accordingly. The received frequency band capability information may also be used for one or more network management functions such as radio resources management, network planning, dimensioning, and coverage enhancement.
