Abstract:
A method and relay node (RN) in a wireless communications network for controlling downlink transmissions to User Equipments (UEs) being served by the RN. An RN transceiver circuit requests each UE to measure and report a Reference Signal Received Power (RSRP) and a UE total downlink interference. An RN receiver circuit receives and forwards the reported RSRP and UE total downlink interference for each UE. An RN processing and control circuit measures an RN total downlink interference; determines which UEs are closely located to the RN based on the reported RSRP of each UE; creates a UE-list with UEs determined to be closely located to the RN and which experience UE total downlink interference similar to the measured RN total downlink interference; determines whether the measured RN total downlink interference exceeds an RN interference threshold; and if so, controls the downlink transmissions to the UEs in the created UE-list.
