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.

Abstract: Presented is an apparatus and methods for determining if a determined systematic imbalance difference between a serving base station and one or more candidate base stations exceeds a threshold value and, if so, then using uplink information as part of a handover mechanism. The selective usage of uplink information in the handover mechanism can improve handover performance without unduly adding to complexity and signaling overhead.

Abstract: Embodiments herein relate to a method in a radio base station for enabling a user equipment to establish a connection in a radio communications network The user equipment is served in a first cell controlled by the radio base station. The radio base station is comprised in the radio communications network. The radio base station detects a failure of a radio link between the user equipment and the radio base station. The radio base station then forwards a user equipment context of the user equipment to a circuitry controlling a second cell when the failure is detected. The user equipment context enables the circuitry controlling the second cell to serve the user equipment and thereby enables the user equipment to establish the connection in the radio communications network.

Abstract: A method in a wireless terminal (110) for sending a measurement report to a serving base station (130) before handover is provided. The wireless terminal (110) and the base station (130) are comprised in a cell in a wireless communications system. The wireless terminal (110) is arranged to use a standard size message or a reduced size message for sending a measurement report before a handover. The wireless terminal (110) obtains (601) information about the cell size and/or the system load. When the cell size exceeds a predetermined value or when the system load exceeds a predetermined value, the wireless terminal (110) sends (605) a measurement report to the base station (130), using the reduced size message.
