  • Publication number: 20190208444
    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: 10327276
    Abstract: A method for evaluating a connection between a first network node and a User Equipment (UE) via a second cell. The first network node serves a first cell. A sending of a first message is initiated. The first message is sent from the first network node to the UE via the second cell. The first message comprises a trigger for the UE to respond by sending a second message comprising feedback relating to the connection to the second cell. A time value difference between the sending of said first message and receiving of said second message in the first network node is obtained. The second message comprises the feedback relating to the connection sent from the UE in response to the first message. Then it is evaluated how the connection shall be used based on the obtained time value difference and the received feedback.

  • Publication number: 20190158237
    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.

  • Publication number: 20190149412
    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.

  • Publication number: 20190149215
    Abstract: There is provided mechanisms for shaping transmission beams in a wireless communications network. A method is performed by a network node. The method comprises acquiring channel measurements for wireless devices served by radio access network nodes using current beam forming parameters and being controlled by the network node. The method comprises determining, based on the channel measurements, desired beam forming parameters for shaping the transmission beams for at least one of the radio access network nodes. The method comprises initiating a gradual change of the current beam forming parameters to the desired beam forming parameters for shaping the transmission beams for the at least one of the radio access network nodes. The gradual change causes a need for network controlled handover to occur for at least some of the wireless devices served by the radio access network nodes.

  • Patent number: 10278082
    Abstract: Network nodes (102, 104), control node (100) and methods therein, for enabling establishment of a neighbor relation between a first network node (102) and a second network node (104) in a wireless network. The control node (100) sends (1:1) or distributes, to network nodes in the network including the first network node (702), a set of reference signals reserved for neighbor relation establishment. The second network node (104) transmits (1:3) one of the reserved reference signals which is then detected by a wireless device (D1) being served by the first network node (102) which then receives (1:4), from the wireless device (D1), a measurement report indicating the detected reference signal that is recognized by the first network node (102) as belonging to the set of reserved reference signals.

  • Patent number: 10237844
    Abstract: A radio network node receives an indication from the user equipment that the user equipment is going to perform an inter-frequency measurement for positioning, which inter-frequency measurement requires measurement gaps. The radio network node may determine a measurement gap pattern for performing the inter-frequency measurement and may signal, to the user equipment, information to initiate use of the determined measurement gap pattern in the user equipment. Alternatively the user equipment configures the measurement gap pattern itself based on a set of pre-defined rules.

  • Publication number: 20190059069
    Abstract: A wireless terminal capable of operating in a discontinuous mode and method for operation facilitate measurements pertaining to position of the wireless terminal. A measurement request message from a radio access network indicates that measurements are to be performed by the wireless terminal on downlink signals transmitted by the base station or by the base station on downlink signals transmitted by the base station. As a result of or after receiving the message, operation of the wireless terminal changes from a discontinuous mode to a modified mode to facilitate performance of the measurements. Relative to the discontinuous mode at least one of following are shortened or eliminated in the modified mode: (i) the non-reception periods, and (ii) the non-transmission periods.

  • Patent number: 10212753
    Abstract: The present disclosure relates to a method performed in a radio communications network which is configured to enable multipath communication. The method comprises providing an explicit indication that a path within a multipath connection is a backup path prior to establishment on or handover to a radio link of the backup path, transmission of the explicit indication to the base station, where it is interpreted. This allows an early indication that the path is a backup path and allows the base station to handle and prioritise use of radio network resources and/or connection characteristics for the radio link. The explicit indication may be in the radio level signalling or in handover signalling.
