Abstract: A first wireless access network node receives feedback information from a second wireless access network node that performs data offload for the first wireless access node. The feedback information relates to one or more of a radio resource usage, a buffer condition, a hardware resource usage or a link quality. In response to the feedback information, the first wireless access network node performs control of the data offload.

Abstract: Systems, methods, and apparatuses for data and/or control offloading and handover in heterogeneous wireless communication networks are provided. Data and/or control packets can be offloaded to a coordinating base station while a user equipment (UE) remains associated with its serving cell. The packets are still transferred between the serving base station and the core network, and the offloaded data and/or control packets are forwarded from the serving base station to the coordinating base station for transmission to the UE. Furthermore, during a handover process, the serving base station and coordinating base station may independently schedule and send a handover command to the UE to reduce the radio link failure rate.

Abstract: A local wireless access network node receives a request to offload at least a portion of data traffic for a user equipment from a macro wireless access network node to the local wireless access network node, where the user equipment is to maintain a wireless connection to the macro wireless access network node after the offload. The local wireless access network node sends a response to indicate whether the local wireless access node has accepted or denied the request.

Abstract: Devices and methods are provided for managing hidden node interference. A communications session between a client node and an access node is affected by interference generated by a hidden relay node. The victim client node and the aggravator relay node are identified by the access node. The access node generates a set of scheduling instructions, which are then provided to the client node. The client node then uses the scheduling instructions to avoid further interference.
