Abstract: Methods, devices, systems, techniques, and computer program products are provided in which an eNB, within a wireless communications network, determining network coverage status relating to a cell served by it, where the eNB supports UE-to-Network relay for a remote UE using direct device-to-device communication between the remote UE and a relay UE connected to the serving cell. Based on a determination of network coverage status, at least one UE is initiated and selected to act as a relay UE. The radio interface link quality of the relay UE can be evaluated and the relay UE can be configured to send an indication of the radio interface link quality to the remote UE. Based on the determined network coverage status and selection of a relay UE, the remote UE is controlled by the eNB for the relay UE discovery and selection either directly or via the relay UE.

Abstract: The present invention addresses methods, apparatus and computer program product for enhanced network sharing with Multimedia Broadcast Multicast Service. Thereby, a mechanism is provided that allows for the information relating to the different IDs used to be provided from a base station to a Multi-cell/multicast Coordination Entity so that the appropriate routing can be determined. The Multi-cell/multicast Coordination Entity may provide the Mobility Management Entity with this information so that control signaling can be properly distributed based on this information and the at least one MBMS SAI. According to the inven tion, a base station indicates one or more PLMN IDs for at least one MBMS SAI to the MCE.
