  • Publication number: 20200252173
    Abstract: A method performed by a network node for managing transmission of Cell Reference Symbols, CRS, wherein the network node operates one or more cells and the network node is configured to transmit the CRS in a first bandwidth mode. When the network node has identified a cell which is not actively serving any UEs, also referred to as an empty cell, the network node applies a reduced CRS bandwidth mode in the first cell in relation to the first bandwidth mode. By applying a reduced CRS bandwidth mode in the empty cell, the overall interference of the CRS from the empty cell is reduced, thereby enhancing the performance in cells actively serving UEs.

  • Patent number: 10694425
    Abstract: The solution presented herein manages the feedback from multiple transmission points by reducing the amount of feedback provided by one or more slave nodes to a controlling master node. To that end, methods and apparatus are provided that determine whether there is a need for the slave node to provide feedback to the master node. Responsive to this determination, the methods and/or apparatus operate the master and/or slave node in a reduced feedback mode that manages the feedback provided by the slave node to the master node such that an amount of feedback provided by the slave node when operating in the reduced feedback mode is less than an amount of feedback provided by the slave node when operating in a full feedback mode.

  • Patent number: 10681605
    Abstract: Systems and methods are disclosed for providing optimized handover decisions for mobile devices participating in streaming services. In one embodiment, a serving base station in a cellular communications network obtains a play out buffer size for a streaming service of a mobile device. The serving base station then makes a handover decision based on the play out buffer size for the streaming service of the mobile device. In one embodiment, the streaming service is a downlink streaming service to the mobile device, and the play out buffer size is a size of a downlink play out buffer at the serving base station for the downlink streaming service to the mobile device. In another embodiment, the streaming service is an uplink streaming service from the mobile device, and the play out buffer size is a size of an uplink play out buffer at the mobile device for the uplink streaming service.

  • 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.

  • 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.
