  • Network node and method for managing transmission of cell reference symbols
    Patent number: 10673590
    Abstract: A method performed by a network node for managing transmission of Cell Reference Symbols, CRS, wherein the network node 110 operates one or more cells and the network node 110 is configured to transmit the CRS in a first bandwidth mode. When the network node 110 has identified a cell 130 which is not actively serving any UEs 120, also referred to as an empty cell, the network node 110 applies (302) a reduced CRS bandwidth mode in the first cell 130 in relation to the first bandwidth mode. By applying (302) a reduced CRS bandwidth mode in the empty cell 130, the overall interference of the CRS from the empty cell 130 is reduced, thereby enhancing the performance in cells actively serving UEs 120.

  • Wireless Device, Higher Layer Node and Methods for Handling Measurement Reporting in a Wireless Network
    Publication number: 20200169904
    Abstract: A wireless device (400), a higher layer node (404) and methods therein, for handling measurement reporting in a wireless network as performed by the wireless device (400). The wireless device (400) detects (4:1) a coverage object being a cell or a beam not contained in a predefined first list of coverage objects for which the wireless device (400) is required to send measurement reports to a lower layer node (402) operable according to at least one of layer 1 and layer 2. The wireless device (400) then measures a radio signal of the coverage object where the measured radio signal fulfils a predefined event condition, and sends (4:2B) a measurement report of said measuring to a higher layer node (404) operable according to one or more layers above layer 1 and layer 2.

  • Technique For Determining Signal Quality
    Publication number: 20200154298
    Abstract: A technique for determining signal quality of a radio access network, RAN, (502) comprising a plurality of transmission-reception points, TRxPs (504), is described. A method aspect of the technique comprises or initiates receiving a control message for determining the signal quality based on a measurement of a reference signal (516.21) from a second TRxP (504.4) at a radio resource. The control message is indicative of the radio resource for the reference signal relative to a synchronization signal (512.1) from a first TRxP (504.1; 504.2; 504.3) other than the second TRxP.

  • Method and apparatus for operating configuration adaptation for interruption of signal transmission
    Patent number: 10484240
    Abstract: The operating configuration at a node in a wireless communication network, at a neighboring node in the network, and/or at one or more wireless devices supported by the network, is updated based on determining timing information for an impending interruption of a radio link in the network to avoid erroneous operation during the impending interruption, which interruption is associated with an external system. The determination of interruption timing, which may be inferred, e.g., from detecting prior interruptions, or which may be known from information about the external system, and the modification of the operating configuration(s) permits the network to operate with greater stability, control, and accuracy during the interruptions than would be possible if the interruptions were simply treated as intermittent radio link failures.
