| 20080268852 | Delayed Base Station Relocation in Distributed Radio Access Networks - The present invention relates to a method for relocating control plane functionality of a serving base station in a mobile communication system comprising a mobile terminal and a plurality of base stations. Further, the present invention relates to a base station in a mobile communication system and to the mobile communication system. To tackle potentially intolerable delay of control signaling due to frequent serving network element relocations in the network architecture the present invention suggests a partial relocation of a serving network element wherein the control plane functionality is relocated but connection to the core network via a gateway is maintained through the previous serving network element. A further aspect of the present invention suggests a total relocation, where control plane functionalities are relocated and where a new connection to the core network is established between the new serving network element and the gateway. Also decision criteria on whether to perform partial or total relocation are provided. | 10-30-2008 |
| 20080276148 | Interference Limitation for Uplink Retransmissions - The present invention relates to a method for transmitting data packets from a mobile terminal to a base station using a hybrid automatic repeat request protocol and soft combining of received data. Further, the present invention provides a base station and a mo-bile terminal both configured to perform the respective method steps. Moreover, a communication system is provided which comprises at least one base station and at least one mobile terminal. In order to decrease the interference caused by retransmissions, the present invention suggests the use of separated channels for initial transmissions and their retransmissions.

| 20080298387 | Harq Protocol Optimization for Packet Data Transmission - The invention relates to a HARQ method using incremental redundancy and providing synchronous retransmissions. Further, the invention relates to a receiving entity and a transmitting entity employing the HARQ method and to a mobile communication system. To optimize conventional HARQ retransmission protocols, the invention introduces a ternary feedback which allows requesting a self-decodable version of a data packet under certain conditions. Further, the ternary feedback is provided in a backward compatible manner using a combination of conventional HARQ feedback signaling and scheduling related control signaling. | 12-04-2008 |
| 20090034487 | HARQ PROCESS RESTRICTION AND TRANSMISSION OF NON-SCHEDULED CONTROL DATA VIA UPLINK CHANNELS - The present invention relates to a method and mobile terminal for performing a data allocation process for scheduled data, non-scheduled user data and non-scheduled control data obeying restrictions on the resource utilization defined by a scheduling grant and at least one non-scheduled grant. Further, the invention relates to a method for transmitting control signaling from a network entity in a radio access network of a mobile communication system controlling the radio resources of mobile terminals to at least one of said mobile terminal and the network entity in a radio access network. In order to reduce the delays to control signaling implied by a conventional HARQ process restriction mechanism the present invention suggests a new categorization of uplink data into scheduled data, non-scheduled user data and non-scheduled control data and a new HARQ process restriction mechanism disabling certain HARQ processes for non-scheduled user data only. | 02-05-2009 |
| 20100281325 | INTERFERENCE LIMITATION FOR RETRANSMISSIONS - The present invention relates to a method for transmitting data packets from a mobile terminal to a base station using a hybrid automatic repeat request protocol and soft combining of received data. Further, the present invention provides a base station and a mobile terminal both adapted to perform the respective method steps. Moreover, a communication system is provided which comprises at least one base station and at least one mobile terminal. The present invention also provides a computer-readable medium for storing instructions that, when executed on a processor, cause the processor to transmit data packets from a mobile terminal to a base station using a hybrid automatic repeat request protocol and soft combining of received data. In order to restrict the interference caused by retransmissions, the present invention suggests controlling the amount of information in the retransmissions and thus the transmission power required for their transmission by TFCS restriction. | 11-04-2010 |
