摘要： Systems and methods are disclosed for adjusting Radio Link Monitoring (RLM), Radio Link Failure (RLF) detection, RLF recovery, and/or connection establishment failure detection for wireless devices in a cellular communications network depending on mode of operation. In one embodiment, a node in the cellular communications network determines whether a wireless device (e.g., a Machine Type Communication (MTC) device) is to operate in a long range extension mode of operation or a normal mode of operation. The node then applies different values for at least one parameter depending on whether the wireless device is to operate in the long range extension mode or the normal mode. The at least one parameter includes one or more RLM parameters, one or more RLF detection parameters, and/or one or more RLF recovery parameters. In doing do, signaling overhead and energy consumption when operating in the long range extension mode is substantially reduced.

摘要： A heterogeneous radio access network (20) comprises a macro layer (22) including at least one macro base station (24) and a micro layer comprising at least one micro base station (26). In an example embodiment a base station node comprises a scheduler (40) and a communication interface (42). The scheduler (40) is configured to prepare a subframe for transmission over a radio interface by configuring the subframe to include a micro layer downlink control channel region in addition to a macro layer downlink control channel region. The communication interface (42) is configured to transmit at least the subframe over the radio interface.

摘要： Presented is an apparatus and methods for determining if a determined systematic imbalance difference between a serving base station and one or more candidate base stations exceeds a threshold value and, if so, then using uplink information as part of a handover mechanism. The selective usage of uplink information in the handover mechanism can improve handover performance without unduly adding to complexity and signaling overhead.

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

摘要： Systems and methods related to reducing a cost of operation and/or manufacture of wireless devices under appropriate conditions are disclosed. In one embodiment, a wireless node in a cellular communication network determines a configuration for a wireless device. In one particular embodiment, the wireless device is a Machine-Type Communication (MTC) device. The configuration includes at least one of a retransmission configuration and an advanced receiver configuration. The wireless device is then configured according to the configuration. In this way, the operation of the wireless device can be more cost efficient, particularly in terms of radio resource and energy efficiency, based on the conditions in which the wireless device is operated.

摘要： The dynamic determination of a handover trigger for triggering handover of a mobile terminal in a wireless network from a source base station to a target base station is based on one or more Key Performance Indicators (KPIs). Each KPI indicates a quality of wireless services provided by the wireless network responsive to a particular handover trigger. If an obtained parameter that indirectly or directly impacts handover performance passes a corresponding performance test, the mobile terminal selects the handover trigger based on the KPIs. If the parameter fails the corresponding performance test, the source base station selects the handover trigger based on the KPIs.

摘要： Systems and methods for network-assisted device discovery for device-to-device (D2D) communications are disclosed. In one embodiment, a base station in a cellular communications network receives a D2D request from a first wireless device to establish D2D communication. In response to the D2D request, the base station selects a second wireless device for D2D communication with the first wireless device based on the D2D request and information regarding wireless devices that are available for D2D communication. The base station then transmits a D2D request acknowledgment to the first wireless device that includes information that enables the first wireless device to establish D2D communication with the second wireless device. The base station also effects transmission of a D2D reconfiguration message to the second wireless device, where the D2D reconfiguration message includes information that informs the second wireless device that the first wireless device has requested establishment of D2D communication.

摘要： In one aspect, the present invention provides methods and apparatuses for detecting that a wireless communication device in a serving cell is experiencing excessive interference variance, detecting a transmission pattern of interfering transmissions giving rise to such variance, and correspondingly adjusting scheduling of the device as a function of the detected transmission pattern, to at least partly avoid the interfering transmissions. An advantageous feature of such operation is that the determination of excessive interference variance and the determination of the transmission pattern associated with that varying interference can be done by a network node, e.g., the device's serving base station, or by the device, without requiring backhaul signaling or other inter-node cooperation in the network.
