摘要： The present invention relates to methods and devices for mobility management in a cellular communications system. A user equipment maintains (21) at least two sets of mobility trigger parameters. Each set of mobility trigger parameters corresponds to a predetermined user equipment speed range. The user equipment determines (22) a speed range that the speed of the user equipment falls into and selects (23), based on the determined speed range, at least one set of mobility trigger parameters to be used for performing mobility-based decisions. If the user equipment is in connected mode a network base station may select a set of mobility trigger parameters to be used for performing handover decisions based on a determined speed range of the user equipment. Advantages are that ping-pong mobility decisions may be avoided and it is sufficient to determine a range for the UE speed, which is less complicated than determining an accurate speed of the UE particularly in idle mode.

摘要： A method in a receiving node for sending an acknowledgement/not acknowledgement 'ACK/NACK' feedback report of received data units over a radio link is provided. When the receiving node have received (301 ) data units in a number of subframes over a first radio link from a sending node, it creates (302) an ACK/NACK feedback report. The report is compressed such that it comprises one single ACK/NACK feedback relating to the data units in the number of received subframes, and the report comprises an indicator indicating said number of received subframes. The receiving node then transmits (303) the created ACK/NACK feedback report to the sending node over a second radio link. The feedback report renders it feasible for the sending node to decide whether a retransmission of any subframe is required or not based on a comparison of the reported number of received subframes with the known transmitted number of subframes per frame, together with the compressed ACK/NACK feedback report.

摘要： 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.
