摘要： 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.

摘要： 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.

摘要： 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.

摘要： The teachings presented herein enable a user terminal to perform a fast recovery from a radio link failure. In one aspect, the improvement in recovery time is achieved by commanding or otherwise causing the user terminal to perform radio link failure (RLF) recovery at a cell that is known to possess the user context, while considering that this cell should yield good radio conditions (if not the best) to the user terminal. A cell may be predefined for use by the user terminal in recovering its radio connection. Based on providing signal strength thresholds to the user terminal, for use in determining whether to use a predefined cell for reconnecting to the network, the user terminal attempts RLF recovery first in the predefined cell. By providing user context to the predefined cell in advance of a recovery attempt by the user terminal, the time for recovery is lessened. Note that the user terminal also may infer which cells are preferred.
摘要翻译： 本文提出的教导使得用户终端能够从无线电链路故障执行快速恢复。 在一个方面，恢复时间的改进是通过命令或以其他方式导致用户终端在已知具有用户上下文的小区上执行无线电链路故障（RLF）恢复来实现的，同时考虑到该小区应该产生良好的无线电条件 （如果不是最好的话）给用户终端。 可以预定义小区以供用户终端在恢复其无线电连接时使用。 基于向用户终端提供信号强度阈值，用于确定是否使用预定义的小区重新连接到网络，用户终端首先在预定义的小区中尝试RLF恢复。 通过在用户终端的恢复尝试之前将预定义的小区提供用户上下文，减少恢复的时间。 注意，用户终端还可以推断哪些小区是优选的。

摘要： 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.
