  • Methods and Apparatus for Supporting Inter-Frequency Measurements
    Publication number: 20170201961
    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.

  • METHODS AND NETWORK NODES FOR EVALUATING A CONNECTION
    Publication number: 20170188248
    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.

  • Methods and arrangement for handling a data transferral in a cellular network
    Patent number: 9510259
    Abstract: A method in a first base station (105) for handling a data transferral in a cellular network (100) is provided. The first base station (105) serves a user equipment (125) via a first cell (115). When the first base station (105) obtains an indication that a second cell (120) provides a coverage for the user equipment (125), the first base station (105) sends a message to a second base station (110) serving the second cell (120). The message commands the second base station (110) to prepare for receiving the uplink data from the user equipment (125) via the second cell (120). The first base station (105) also sends a request to the user equipment (125). The request commands the user equipment (125) to prepare for sending the uplink data both via the first cell (115) and via the second cell (120) in respective separate intra frequency transmissions.
