  • Patent number: 9888420
    Abstract: We disclose various embodiments of methods and apparatus for processing handovers of mobile terminals between base stations of a wireless communication system. An example handover algorithm used for this purpose enables the handover threshold to be increased for some mobile terminals, on a terminal-by-terminal basis, thereby individually expanding the range of the serving cell for each of such terminals. In an example embodiment, the handover-threshold determination is carried out based on physical-resource-block usage of the target cell. The extent of the cell-range expansion depends on whether or not the reference signals of the serving and target cells interfere with each other. Embodiments of the disclosed handover algorithm can advantageously reduce the number of failed handovers by allowing some communication sessions to run to completion before a handover is triggered.

  • Patent number: 9769706
    Abstract: Resources are reserved for handover signaling. Handover reliability is thereby improved since the primary interference for handover signaling will be from the handover signaling of nearby cells (e.g., as opposed to data traffic). Given the relatively sparse nature of handover signaling, a significant reduction in interference may be achieved in a network employing this technique in comparison to conventional networks. In some implementations, a set of neighboring access points cooperate to determine which resources are reserved for handover signaling. In some implementations, resources for handover signaling are reserved on a network-wide basis or an access point cluster-wide basis.

  • Patent number: 9668192
    Abstract: A first network node has first antenna nodes located along a track and associated with a first cell. Some of them serve a first cell overlap region that overlaps a second cell overlap region of second antenna nodes connected to a second network node. Some first antenna nodes form downlink beams in a same direction with power levels controlled such that respective amounts of overlap between the downlink beams and respective power levels of the downlink beams jointly cause the first cell's overlap region to emulate a cell border for a user equipment travelling at high speed. Emulated cell border signal power is lower at locations closer to an emulated cell outer edge than at more distant locations. Emulated cell border length is sufficient to cause the travelling user equipment to be within the emulated cell border long enough to successfully perform a handover between the first and second cells.

  • Patent number: 9648523
    Abstract: In a handover operation an access terminal is handed over from a source access point to a target access point. To facilitate efficient identification of a target access point, a handover operation may be initiated by the target access point. A candidate frequency search also may be invoked to confirm that an access terminal identified by a target access point for a handover is in the vicinity of the target access point. A source access point may verify whether an access terminal is in a vicinity of a target access point to determine whether to perform a handover operation. A source access point may handle potential ambiguity between several target access points by sending handover commands to each of these target access points. An access terminal also may assist in the determination of whether to perform a handover operation.
