    Abstract: A user equipment (UE) located in an extended-range area of a neighbor base station cell in a communication network, such as a low-power cell in a heterogeneous network, can inform its serving base station, such as a macro cell overlying the low-power cell, of the UE's capability of canceling interference from other cells' transmissions. That capability information enables the serving cell to decide based on more information whether range extension of the neighbor cell is beneficial for a number of UEs, and can result in more efficient radio resource utilization.

    Abstract: The invention relates to a method for selecting a radio access point of a network, and a method for transmitting information on at least two radio access points of a network to a mobile terminal. Further the invention relates to an adapted mobile terminal and control entity for performing the methods, respectively. To minimize the transmission delays of acknowledgement messages sent from a mobile terminal to a control entity, the invention provides an access point selection mechanism that determines for a respective one of the at least two radio access points, a selection criterion associated to the respective radio access point. This selection criterion may be based on a transmission delay for sending acknowledgement messages via a respective access point to a control entity. Based on the determined selection criterion the mobile terminal selects one of the at least two radio access points, and sends an acknowledgement message to the control entity through the selected radio access point.

    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.
