Abstract: Network node and UE, and methods therein for signaling system information, SI, to UEs. The method in the network node comprises transmitting SIto one or more UEs, where the SI comprisesmultiple alternative sets, where each set assigns different values to one or multiple radio system parameters. The method further comprises determining which set, out of the multiple alternative sets, that should currently be applied for a UE, and transmitting an SI selection signal to the UE, the SI selection signal indicating the determined set, thus enabling the UE to apply currently appropriate radio system parametersalso in unfavorable radio conditions.The UE may be an MTC device (Machine Type Communication).

Abstract: The disclosed solution dynamically selects a handover trigger for triggering handover of a mobile terminal (300) in a wireless network from a source base station (100) to a target base station based (200) on one or more Key Performance indicators (KPls). Each KPI indicates a quality of wireless services provided by the wireless network (50) responsive to a particular handover trigger. A trigger selection circuit (520) selects one of multiple candidate triggers as the handover trigger based on a comparison between corresponding KPIs for different ones of the candidate triggers.

Abstract: Devices and methods for adjusting resource management procedures in heterogeneous communication networks (105) are disclosed. In one aspect a method for adjusting radio resource management procedures in a mobile device (120) communicating with a node (110, 115) operating in a cell in a heterogeneous communication network (105) includes transmitting a first message to the node (705, 1205) the first message including a request for cell information receiving (710, 1210) a second message transmitted from the node the second message including the requested cell information measuring (715, 1215) signal reception information processing the received cell information and measured signal reception information to determine an adjustment to a radio resource management procedure and adjusting (725, 1225) the radio resource management procedure based on the determined adjustment. The first and second messages may be radio resource control RRC messages such as RRC connection request and response messages.

Abstract: Devices and methods for adjusting resource management procedures in a mobile device communicating with a node operating in a cell in a heterogeneous communication network are disclosed. In one aspect a method for adjusting resource management procedures in a mobile device communicating with a node operating in a cell in a heterogeneous communication network includes receiving a signal including a reference signal transmitted from the node during a predetermined time period measuring signal reception information including reference signal power values at predetermined time intervals during the predetermined time period measuring speeds of movement of the mobile device at the predetermined time intervals determining a reference signal power variation value based on the variability of the measured reference signal power values comparing the determined reference signal power variation value with a predetermined power threshold value for a given measured speed determining cell information based on the comparison determining an adjustment to a resource management procedure based on the determined cell information and adjusting the resource management procedure based on the determined adjustment In exemplary embodiments of the disclosed methods and devices the cell information may be determined by using one or more of reference signal power variation reference signal quality variation signal to interference plus noise ratio variation Doppler frequency shift antenna location handover triggers and eel! signal power information.

Abstract: 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.
