摘要： In an improved and reliable method and arrangement allowing a user equipment to acknowledge the re-pointing over target cell in the HS-DSCH serving cell change procedure, wherein a Media Access Control (MAC) frame include information indicates the acknowledgement. In one embodiment the MAC frame contains only the Scheduling Information (SI) field with a coding not normally used, e.g. TEBS=O and HLID =0 (TEBS = Total E-DCH Buffer Status; HLID = Highest Priority Logical Channel ID). Since the MAC frame is protected by Hybrid Automatic Repeat Request (HARQ), high reliability is ensured. Also, the MAC frame is transmitted to all cells in the active set, so that robustness is ensured also during imbalance situations.
