    摘要： A method for cell selection comprises obtaining of user equipment specific information for a user equipment that is present in a first cell of a first base station. The user equipment specific information comprises information of a prevailing radio situation and information of a present decoding performance. A present capability of the user equipment for handling increased interference and a measure of a cell selection offset required to cover the user equipment by a second cell is estimated from the user equipment specific information. It is decided on modifying a cell selection offset for handover between the first cell and the second cell, in dependence on the estimated present capability of the user equipment for handling increased interference and the cell selection offset required to cover the user equipment by the second cell.

    摘要： The present disclosure relates to a method and a serving radio base station (RBS) for link adaptation (LA) of PDCCH. The method includes obtaining information about a reduced power subframe (RPS) pattern used by a neighbouring RBS. An indication of a reception quality of the PDCCH at a user equipment (UE) is obtained. A determination is made whether the obtained indication relates to an RPS or a non-RPS according to the obtained information. A first LA loop for a PDCCH to the first UE is controlled. The first LA loop relates to non-RPS. A second LA loop for the PDCCH to the UE is controlled. The second LA loop relates to RPS. At least one of the first and second LA algorithms, depending on the determining, is controlled based on the obtained indication of a reception quality.

    摘要： Methods and arrangements in a first node for requesting a status report from a second node. The first node and the second node are both comprised within a wireless communication system. The status report comprises positive and/or negative acknowledgement of data sent from the first node, to be received by the second node. The methods comprises the steps of: detecting if any data units have been lost during the transmission, generating a status report, based on the made detection concerning lost data units, buffering the generated status report in a buffer, updating the buffered status report when a change concerning lost data units is detected, receiving a trigger for sending a status report to the second node, and transmitting the status report to the second node, as a response to the received trigger.
