Abstract: Method and arrangement in a first base station for scheduling in a TDD wireless network, which wireless network comprises the first base station serving a user equipment, and a second base station. The method comprises detecting that the second base station uses a different TDD configuration, instructing the user equipment to provide a signal strength measurement report based on a signal received from the second base station, receiving the measurement report, and allocating resources to the user equipment based on the received measurement report. Thereby is allocation of resources in TTIs not having the same uplink-downlink direction in the first base station and the second base station respectively, is avoided for the user equipment, when the received signal strength measurement report indicates that such allocation is appropriate. Also, a method and arrangement in a user equipment for scheduling in a TDD wireless network is described.

Abstract: The present disclosure provides systems and methods for selecting a resource for a direct device-to-device (D2D) communication link between wireless devices in a cellular communication network. In one embodiment, a control node in a cellular communication network selects a resource for a direct D2D communication link between a first wireless device and a second wireless device based on one or more criteria including a service area type of a service area within the cellular communication network in which the first wireless device and the second wireless device are located. The service area type is either homogeneous or heterogeneous. The control node communicates an indicator of the resource selected for the direct D2D communication link to the first wireless device and/or the second wireless device. Thereafter, the first and second wireless devices communicate over the direct D2D communication link using the selected resource.

Abstract: The present disclosure relates to providing a method of improving data rates in a heterogeneous network which is composed of macro cells and pico cells. User equipment is connected to the network via a macro base station serving a macro cell or a low power node serving a pico cell. A signal strength indicator is received from one or more UEs located in a macro cell and adjacent one or more pico cell. The location of a UE within a region of a macro cell or a pico cell is identified according to the signal strength indicator. Then, a weak coverage area of macro cell is identified according to the signal strength indicator and a beam forming antenna of a macro base station serving the macro cell where the UE is located, is directed to steer the antenna beam to an area of the cell requiring an improved signal strength indicator.

Abstract: This disclosure teaches a method and apparatus for radio link failure recovery by a User Equipment (UE). The example UE includes one or more controllers that are configured to store cell access information for a target cell that is the target for an impending handover from a serving cell, and for a backup cell that is selected by the UE from among a set of neighbouring cells that includes the target cell. Advantageously, in case the handover to the target cell fails, the one or more controllers are configured to retrieve the cell access information stored for the backup cell and to use that information for re-establishing connection in the backup cell. The UE selects the backup cell, for example, as the neighbouring cell other than the target cell having the strongest signal conditions with respect to the UE.

Abstract: Methods and arrangements for autonomous handover are provided. In a step, a mobile terminal sends a measurement report to a first network node. In another step, the mobile terminal starts a timer for measuring a wait period. In a further step, the mobile terminal waits until the wait period has expired. In still another step, the mobile terminal measures a signal used for mobility evaluations from the first radio network node. In yet another step, the mobile terminal performs random access to the second radio network node, if appropriate. Furthermore, the first radio network node sends information about random access channel (RACH) characteristics. Moreover, the first radio network node may send the wait period to the mobile terminal. In another step, the first radio network node sends the terminal context to neighbouring radio network nodes.
