20090042572 | Cell change in cellular networks - The invention relates to a handover or cell change procedure in a cellular radio communications system comprising a mobile user terminal present in a serving cell and having multiple radio resources simultaneously allocated for communication with a base station of the cell. In this procedure, when there is a need for a cell change, the multiple radio resources are sequentially replaced with radio resources allocated to the terminal for communication with at least one base station having an associated cell different from the serving cell. This cell change procedure provides macro diversity without requiring the complexity of soft handovers and has enhanced service coverage and handover robustness compared to hard handover. | 02-12-2009 |
20110274055 | PROVIDING A SERVING HS-DSCH CELL CHANGE ACKNOWLEDGEMENT - 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= | 11-10-2011 |

20120314607 | UPLINK LOAD PREDICTION USING KALMAN FILTERS - Method and arrangement in a base station for providing an input parameter in an algorithm for predicting uplink load in a cell in a wireless communication system. The cell comprises at least one user equipment. The method comprises obtaining SIR target value associated with the user equipment, measuring SIR value on a signal sent from the user equipment, comparing the difference between the obtained SIR target value and the measured SIR value with a threshold limit value, selecting the SIR value as input parameter in the uplink load prediction algorithm for the user equipment, if the difference between the obtained SIR target value and the measured SIR value is bigger than the threshold limit value. Otherwise selecting the SIR target value as input parameter in the uplink load prediction algorithm for the user equipment. | 12-13-2012 |
