  • Publication number: 20180270729
    Abstract: A method performed by a first radio network node for handling mobility of a wireless device in a wireless communication network. The first radio network node provides radio coverage over a first service area using a first reference signal for identifying the first service area in the wireless communication network. A second radio network node provides radio coverage over a second service area using a second reference signal for identifying the second service area in the wireless communication network. The first radio network node receives a measurement report from the second radio network node, which measurement report indicates a second signal strength or quality of a second dedicated beam used for data transmission for wireless devices in the second service area. The first radio network node performs a mobility decision for the wireless device taking the second signal strength or quality, indicated in the received measurement report, into account.

  • Publication number: 20180184387
    Abstract: Systems and methods are disclosed herein relating to beam-switching in a wireless system. In some embodiments, a method of operation of a User Equipment device (UE) that transmits and/or receives to and/or from a source Antenna Node (AN) on a source beam comprises performing a Mobility Reference Signal (MRS) search to attempt to detect MRS transmitted by one or more candidate ANs for one or more candidate beam. The method further comprises, if one or more conditions that are indicative of the MRS search being unsuccessful are met, transmitting an indication that the MRS search was unsuccessful. In this manner, one or more network nodes are informed that an action(s) (e.g., assisted beam-formed MRS transmission and/or increasing MRS transmit power at candidate AN(s)) needs to be taken to enable a successful MRS search by the UE.

  • Patent number: 9955337
    Abstract: Mechanisms are provided to enable the identification of a UE in both the cellular network (e.g., a 3GPP network) and the WLAN. In some aspects, the UE is provided with information enabling it to find the transport network layer, TNL, address (e.g., an IP address) of the WT and an identifier of the UE. Using the TNL of the WT, the UE can establish a connection towards the WT (either connectionless or connection oriented) and provide the UE identity. The WT and eNodeB exchange information about the UE ID, and the UE is identified in both the 3GPP network and the WLAN. The WT is a logical node and may be integrated in the eNodeB, in a WLAN node (e.g. access controller, access point), standalone or somewhere else. Once identified, user data can be sent to the UE via the WT.

  • Patent number: 9936432
    Abstract: The present disclosure concerns movements, such as handovers, of user equipments (UEs) 120a-e from one radio cell 130a to another radio cell 130b. Disclosed herein are methods as well radio network nodes 110a, 110b. A radio network node 110a, 110b may, for example, select the most suitable UE(s) 20a-e to move from a source radio cell 130a to a target radio cell 130b in case the traffic load in the source radio cell 130a is below or equal to the traffic load of the target radio cell 130b. Hereby it is made possible to improve the resource utilization.

  • Patent number: 9900836
    Abstract: A method in a radio network node for selecting a second SCell of a wireless device. The radio network node sends (201) data to a network node, upon a request to release the wireless device from a first connected state, in which the wireless device is connected to a first PCell and configured with a first SCell. The data indicates the first PCell and the first SCell. The radio network node retrieves (202) the sent data when the wireless device enters a second connected state. Then, the wireless device is connected to a second PCell. The radio network node compares (203) the second PCell with the first PCell and the first SCell. When the second PCell is the same as one of the first PCell and the first SCell, the radio network node selects (204) as the second SCell the other of the first SCell and the first PCell.
