| 20090207820 | TRANSMISSION OF DATA PACKETS IN A WIRELESS COMMUNICATION NETWORK - The invention relates to a method for retransmitting data packets in a network. Further, the invention relates to an adapted system for performing the method. To improve the robustness in the transmission of an acknowledgment message by a mobile terminal to the network, while minimizing a signaling overhead, the invention provides mechanisms that optimize the retransmission of data packets and manage acknowledgement messages. The mechanisms disclosed are particular applicable to heterogeneous radio access networks. | 08-20-2009 |

| 20100184437 | Radio Resource Management Based on Parameters Indicating Imbalance between Uplink and Downlink - The present invention relates to methods and arrangements for radio base stations of a wireless communication network, enabling each radio base station to transmit parameters indicating imbalance between UL and DL to adjacent radio base stations, when it is triggered to do so. The adjacent radio base stations can then use the parameters for radio resource management decisions such as HO decisions, whenever needed. | 07-22-2010 |
| 20100298001 | Speed-Dependent Adaptation of Mobility Parameters with Dual Speed Measurement - Mobility parameters, such as those used in handoff decisions, are based on the speed of User Equipment (UE) ( | 11-25-2010 |
| 20110080825 | Method and Apparatus for Radio Link Failure Recovery in a Telecommunication System - The teachings presented herein enable a user terminal to perform a fast recovery from a radio link failure. In one aspect, the improvement in recovery time is achieved by commanding or otherwise causing the user terminal to perform radio link failure (RLF) recovery at a cell that is known to possess the user context, while considering that this cell should yield good radio conditions (if not the best) to the user terminal. A cell may be predefined for use by the user terminal in recovering its radio connection. Based on providing signal strength thresholds to the user terminal, for use in determining whether to use a predefined cell for reconnecting to the network, the user terminal attempts RLF recovery first in the predefined cell. By providing user context to the predefined cell in advance of a recovery attempt by the user terminal, the time for recovery is lessened. Note that the user terminal also may infer which cells are preferred. | 04-07-2011 |
| 20110103347 | Adaptation of Handover Command Size In A Mobile Telecommunication Network - The present invention relates to a method and a base station for determining a handover command based on mobility related parameters such as a handover margin or a time value required to trigger the handover. | 05-05-2011 |
| 20110207485 | User Equipment, Radio Base Station and Methods Therein - Embodiments herein relate to a method in a user equipment for handling a radio link failure in a radio communications network. The user equipment is served in a first cell controlled by a radio base station. The radio base station is comprised in the radio communications network, The user equipment detects a first indication of a failure of a radio link between the user equipment and the radio base station. The user equipment then transmits a second indication of radio link failure to the radio base station when the first indication is detected. | 08-25-2011 |
