Measurement Control for UE Relay Selection in ProSe-based UE-to-Network Relay

摘要

Within a wireless communication network, an eNB determines a network coverage state for a cell served by an eNB, where the eNB uses direct device-to-device communication between the remote UE and the relay UE connected to the serving cell Methods, devices, systems, techniques, and computer program products are provided that support UE-to-network relay for a remote UE. Based on the determination of the network coverage state, 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 transmit an indication of the radio interface link quality to the remote UE. Based on the determined network coverage status and selection of the relay UE, the remote UE is controlled by the eNB for relay UE discovery and selection either directly or through the relay UE.
