  • Patent number: 10721638
    Abstract: The present invention relates to a method and apparatus for testing mobile terminals in an OFDMA system, in which all or part of available downlink radio resources in a cell are transmitted. A processing unit in a test apparatus splits a set of contiguous resource blocks into separate contiguous portions. A first contiguous portion of the set of resource blocks is allocated to users of a first type, and a second contiguous portion of the set of resource blocks is allocated to users of a second type. A transmitter in the test apparatus transmits test signals to the users of the first type and the second type using the at least one contiguous set of resource blocks.

  • Patent number: 9445339
    Abstract: The invention relates to a method for supporting cell change between frequency layers. The method is performed in a Radio Network node of a wireless communication network deploying two frequency layers. The Radio Network node serves a User Equipment in a cell of a first of the two frequency layers. The User Equipment is configured to perform measurements on the first frequency layer, and to exclude measurements on a second of the two frequency layers. The method comprises receiving information from the User Equipment related to a coverage of a target cell of the second frequency layer, and determining whether to change to the target cell based on the received information.

  • Patent number: 9191851
    Abstract: A telecommunications node (28) comprises a communication interface (36) and a parameter controller (40). The node (28) acquires timing advance (TA) information and angle of arrival (AoA) information through the communication interface (36). The timing advance (TA) information and angle of arrival (AoA) information are based on uplink signals received over a radio interface (32) from one or more wireless terminals (30) that are involved or have been involved in handover. The parameter controller (40) uses the timing advance (TA) information and the angle of arrival (AoA) information to make a determination of size and shape of a cell of a radio access network.

  • Patent number: 8892103
    Abstract: The invention relates to a method for supporting cell change between frequency layers. The method is performed in a UE and/or a RN node of a wireless communication network deploying two frequency layers. The RN node serves a UE in a cell of a first of the two frequency layers. The UE is configured to perform measurements on the first frequency layer, and to exclude measurements on a second of the two frequency layers. The method comprises receiving (610) measurement results from the UE, for measurements performed on a cell of the first frequency layer, determining (620) a location of the UE based on the measurement results, assessing (630) a coverage of a target cell of the second frequency layer based on the location and a coverage map for the two frequency layers, and determining (640) whether to change to the target cell based on the assessment.

  • Patent number: 8526357
    Abstract: The present invention relates to methods and arrangements for handling unreliable scheduling grants in a WCDMA-communication system. A user equipment detects that a received scheduling grant is unreliable and adjust its serving grant based on that information. The user equipment is also able to report continuously received unreliable grants as an event to the network, allowing the network to adapt its operation to reduce the unreliable grants.

  • Publication number: 20130070663
    Abstract: The present invention relates to a method in a serving base station (130) for controlling handover of a relay node (140) to a target cell (150A) controlled by a target base station (150). The method comprises the steps of obtaining information (91) indicating if the target base station and/or the target cell supports handling of relay nodes or not; avoiding handover of said relay node to said target cell in case the target base station and/or the target cell does not support handling of relay nodes (94). The invention furthermore relates to a base station for performing said method.
