摘要： A radio network node and method for improved control of handover decisions of a User Equipment (UE) in a wireless communications network. The UE is in a served cell and is moving towards a neighboring cell. The network node obtains neighboring cell characteristics and determines a mobility threshold based on the obtained neighboring cell characteristics. The handover decisions of the UE to the neighboring cell are then controlled based on the determined mobility threshold.

摘要： Methods and arrangements for use in a respective node and mobile terminal in a first system associated with a first frequency band for radio communication, for supporting avoiding or reducing interference in a second frequency band associated with a second system, which second frequency band is adjacent to the first frequency band. The method for use in the node comprises detecting activity of the second system in the second frequency band and adjusting the bandwidth used by the node for communication, based on characteristics of the detected current activity of the second system in the second frequency band, such that interference to the second frequency band, from radio communication associated with the node, is adapted to the second system activity in said second frequency band. The method further comprises providing information of said adjustment to at least one mobile terminal. Further, information of said adjustment could be provided to neighboring nodes.

摘要： A system includes a first device (110) to classify data as one of a control message or a non-control message, and provide the classification of the data to a second device (122). The second device (122) receives the classification of the data, receives information associated with a resource (460), calculates an expected interference associated with the resource (460) based on the information associated with the resource (460), and allocates, to the resource (460), data classified as a control message when the expected interference corresponds to a low expected interference.

摘要： A method and a network node (110) for determining an indication of interference mitigation in a receiver comprised in a user equipment (120) are provided. The network node (110) receives, from the user equipment (120), a first set of measures and a second set of measures. The first set of measures relates to a signal received by the user equipment (120) and the second set of measures relates to the same signal. The first set of measures was obtained by the user equipment (120) prior to processing of the signal in the receiver, and the second set of measures was obtained by the user equipment (120) after processing of the signal in the receiver. Next, the network node (110) determines (202) the indication of interference mitigation based on the first and second sets of measures.

摘要： A base station (12) and a method therein for adapting a triggering threshold for cell re-selection measurements performed by a mobile terminal (20) served by a macro cell (14). The macro cell (14) is supported by the base station (12), and the base station (12) and the mobile terminal (20) are comprised in a wireless communications network (10). The base station determines a serving cell signal strength threshold to be used for triggering cell re-selection measurements by the mobile terminal (20) in dependence on the availability of small cells (18a,18b) within or neighboring the macro cell (14). The base station (12) further transmits the determined serving cell signal strength threshold to the mobile terminal (20).

摘要： A method may be provided in a wireless terminal to modify access to a Radio Access Network. The method may include providing a barring rate at the wireless terminal and providing a barring rate modifier at the wireless terminal. A modified barring rate may be provided at the wireless terminal responsive to the barring rate and the barring rate modifier with the modified barring rate and the barring rate being different. A random number may be provided at the wireless terminal responsive to attempting to access the Radio Access Network, and access of the wireless terminal to the Radio Access Network may be blocked responsive to the random number failing to satisfy a threshold of the modified barring rate. Related wireless terminals, network nodes, and network operations are also discussed.

摘要： Systems and methods are disclosed for selecting resources for direct device to device (D2D) communications in a cellular communication network. Preferably, resources for the direct D2D communications are selected to minimize, or at least substantially reduce, interference that results from the direct D2D communications in the cellular communication network. In general, either an uplink resource or a downlink resource of the cellular communication network is selected for a direct D2D communication link between a first wireless device and a second wireless device in order to minimize, or at least substantially reduce, interference caused to a third wireless device that uses the same uplink and downlink resources in the same and/or a neighboring cell of the cellular communication network.

摘要： The present invention relates to methods and arrangements in a UE and a RBSin a wireless communications system, enabling an efficient handover of the user equipment. The method comprises transmitting (810) a message to the serving radio base station, the message indicating the need for a handover to a cell of a target radio base station. It also comprises observing (820) an indication that a handover request transmitted by the serving radio base station is rejected by the target radio base station, and selecting (830) a recovery cell based on the observed indication when detecting a radio link failure.
