  • Publication number: 20200296625
    Abstract: The present invention relates to a source node, a target node and methods for supporting re-distribution of load from a source cell to a target cell in a wireless network, wherein the target cell is a combined cell comprising a plurality of spatially separated sectors that are configured for downlink and/or uplink communication on a same carrier frequency. Performed in the source node, the method comprises receiving, from the target node, a load report comprising traffic load in one or more of the plurality of spatially separated target sectors comprised in the target cell. Reference signal measurements defining radio conditions for one or more of the target sectors comprised in the target cell are retrieved from one or more wireless devices served by the source node.

  • Patent number: 10716010
    Abstract: The present invention relates to an improved predicting of target carrier radio conditions in a communication network. The improved prediction is achieved by acquiring, by a first network node, measurement data based on radio signals at a source carrier and a first target carrier. Subsequently, a target carrier radio condition prediction function is identified by the first network node or a second network node.

  • Patent number: 10021608
    Abstract: A method in a radio network node for determining whether a wireless device is a suitable candidate for handover to a target cell for load balancing reasons. The radio network node serves a source cell. The method includes determining a first level of coverage of the target cell based on a first measurement report. The method further includes storing measurement data obtained from a second measurement, being at least one of a layer 2 and a layer 1 measurement. The method further includes establishing a correlation between the determined first level of coverage and the stored measurement data and updating statistical data based on the established correlation. The method further includes determining whether the wireless device is a suitable candidate for handover to the target cell for load balancing reasons, based on the updated statistical data.

  • Patent number: 9894543
    Abstract: A method and network node (400) for supporting evaluation of usage of a radio network feature in radio communication between wireless devices (402) and the network node. The network node (400) retrieves (4:1) statistical information regarding the usage of the radio network feature, and reports (4:5) the statistical information to an Operation and Maintenance, O&M, node (404). The O&M node then uses (4:6) the statistical information for evaluating how measured performance (4:3) of the radio network is related to the usage of the radio network feature.
