摘要： 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.

摘要： 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.

摘要： 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.

摘要： Embodiments herein relate to a method in a user equipment (10) for acquiring system information relating to a cell (11,14) in a radio communications network. The cell (11,14) is served by a network node (12,12′,15) and the user equipment (10) is capable of receiving signals on more than one downlink carrier simultaneously. The user equipment (10) creates autonomous gaps on a downlink carrier, which downlink carrier to use for creating autonomous gaps on is based on a received indication from the network node (12,12′,15) and/or a pre-determined rule. The indication or pre-determined rule specifies the downlink carrier. The user equipment (10) then acquires the system information of the cell (11,14) on the downlink carrier using the created autonomous gaps.

摘要： Time-aligned handover for a mobile device is described herein. The time-aligned handover is achieved by determining a time difference between serving and target cells and determining a target propagation delay based on the time difference. In some cases, the target propagation delay may further be determined based on a serving propagation delay between the serving cell and the mobile device. A target transmission time is calculated based on the target propagation delay. The mobile device uses the target transmission time to time align transmissions to the target cell during handover.

摘要： The present invention relates to a method and an arrangement (102, 104, 106, 202, 302, 304, 502, 504, 702, 704, 1000, 1014) for prioritizing one of multiple cell-related mobility decisions associated with multiple parallel mobility events being triggered, comprising recognizing parameter settings associated with at least two parallel mobility events being triggered (steps 406, 604; 806), evaluating the parameter settings for determining which cell-related mobility decision to prioritize (steps 408; 606; 808), and performing a task according to the cell-related prioritized mobility decision (steps 410, 608; 814), to achieve a cell re-selection in idle mode or a hand over in connected mode. By applying multiple parameter settings a better performance is achieved as can be seen by a reduced percentage of time a User Equipment (102, 202, 302, 502, 702, 1000) is not connected to the best cell.

摘要： A method in a user equipment (121) for adjusting a transmit timing of uplink transmissions to a network node (110) in a telecommunications system (100) is provided. The user equipment (121) is configurable with more than one aggregated serving cells. The more than one aggregated serving cells are divided into one or more groups of serving cells based on a timing advance value of each of the aggregated serving cells. The one or more groups of serving cells each comprises a timing reference serving cell. The reception timing of a downlink transmission from a timing reference serving cell is used as a timing reference for the transmit timing of uplink transmissions for the serving cells in the group of serving cells comprising the timing reference serving cell, respectively. The user equipment (121) determines a change to a second timing reference serving cell in a group of serving cells, which second timing reference serving cell is different from a first timing reference serving cell currently being used as the timing reference serving cell for the group of serving cells. Then, the user equipment (121) applies an incremental adjustment of the transmit timing of uplink transmissions for the serving cells in the group of serving cells with respect to a timing reference based on the reception timing of a downlink transmission from the second timing reference serving cell in the user equipment (121).A user equipment, a method in network node and a network node are also provided.
