Abstract: Systems and methods are disclosed for controlling cell selection between a high power base station and a neighboring low power base station in a cellular network. In one embodiment, a primary direction of traffic flow for a user equipment located within a transition zone between a high power base station cell of the high power base station and a low power base station cell of the low power base station is determined to be either an uplink direction or a downlink direction. Cell selection for the user equipment is then controlled based on the primary direction of traffic flow for the user equipment such that selection of the high power base station cell is favored if the primary direction of traffic flow is the downlink direction and selection of the low power base station cell is favored if the primary direction of traffic flow is the uplink direction.

Abstract: A method of decreasing radio link failure in challenging mobility scenarios for a user equipment (UE), device working in a cellular telecommunication network with a base station of each cell is disclosed. The method comprises measuring signal conditions for serving cell and neighbouring cells periodically; and estimating channel variations and comparing the estimate with a threshold value such that, when channel variations are determined to exceed a channel variations threshold, performing an accelerated procedure comprising predicting whether handover is likely to occur in connection with the next scheduled measurement instant based on the signal measurements such that when handover is predicted, the procedure directly proceeds with sending an initial measurement report transmission request. Thereby handover delay can be reduced such that risk of radio link failure is reduced at significantly varying signal conditions. A UE device and a computer program are also disclosed.

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.
