Capability reporting for relay nodes in wireless networks
First Claim
1. A method for managing a wireless communication network that includes a wireless relay node for wirelessly transmitting signals to and wirelessly receiving signals from one or more access terminals, or to and from one or more other relay nodes, or to and from one or more of both, via an access link, and for wirelessly transmitting signals to and wirelessly receiving signals from a donor node, via a backhaul link, the method comprising, in a network node:
- receiving, from the relay node, a report indicating separate frequency band capabilities for the access link and the backhaul link, wherein said frequency band capabilities for the access link or the backhaul link include aggregated component carrier frequencies within each frequency band that are supported by the relay node for the access link or the backhaul link, wherein the component carrier frequencies are aggregated in one of the following deployments;
contiguous, non-contiguous, or a hybrid of contiguous and non-contiguous; and
applying the indicated frequency band capabilities in one or more network management tasks.

Abstract
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.
