Summary:In one or more embodiments, the present invention provides a method and apparatus for "early" triggering of a BSR in a relay node. Doing so is advantageous, for example, in reducing the overall time between a UE's transmission of data to a relay node on an access link and the corresponding transmission of that data from the relay node to a donor base station on a backhaul link. Of course, that example is non-limiting. More broadly, in at least one embodiment, the present invention provides for triggering a BSR in the relay node right after learning that there is at least one UE connected to the relay node that wants to transmit UL data. Further, one or more embodiments provide a simple method and apparatus for using a relay node BSR to inform a donor base station about the scheduled status of UEs supported by the relay node.
