| 20090029653 | METHOD AND STATION FOR TRANSMITTING DATA IN A RADIO COMMUNICATION SYSTEM - In a communication system, a first transmitting station transmits a transmission signal to a first receiving station for transmitting a sequence of data via a radio interface. The radio interface is monitored with respect to an interference signal from an interference source prior to transmission via at least one of the first transmitting station and the first receiving station. The transmission only begins if the radio interface is sufficiently free from interference for a moment in time. | 01-29-2009 |
| 20090135941 | Method for Digital Wireless Message Transmission Over a Broadband Mobile Radio Channel - In an OFDM multi carrier modulation method, M sub-carriers are used in a frequency band of a broadband mobile radio channel and several symbols are used in a time band. With application of a MIMO multi-antenna method with T transmitting antennae and R receiving antennae, for all sub-carriers and all symbols, a single, pre-determined, channel-matched transmission strategy is used, which is described by a maximum of T*R complex values on the signal side, independent of the species of the MIMO multi-antenna method and independent of the size of the frequency/time bands. | 05-28-2009 |
| 20090143088 | Dynamic Allocation of Radio Resources in a Multicarrier Communication System - Communication carried out over a frequency band divided into a plurality of subcarriers by messages transmitted between a first radio station and a second radio station in a plurality of hops between respectively adjacent radio stations arranged in hierarchical levels. A subset of the subcarriers is used for each hop. The subsets used are allocated by at least one higher level radio station and the composition of at least one of the subsets used varies over time. | 06-04-2009 |
| 20090220027 | Method For Coding Data Symbols - Data symbols, transmitted by OFDM radio using at least two transmission antennae, are coded by a DSTBC coding and a DSTFBC coding. Two adjacent data symbols of a selected sub-carrier are provided for initializing a DSTFBC coding in a sub-carrier direction and are used for DSTFBC coding of similarly positioned data symbols in further sub-carriers in the sub-carrier. The DSTFBC coding is carried out from the data symbols of the first sub-carrier direction. In each sub-carrier the two data symbols formed by DSTFBC coding are used for initializing a DSTBC coding in the OFDM symbol direction. In the reverse direction, two sequential DSTBC coded data symbols on a first sub-carrier for initializing a DSTFBC coding in a sub-carrier direction and are used for DSTFBC coding of similarly positioned data symbols in further sub-carriers for DSTFBC coding from the data symbols of the first sub-carrier over the adjacent sub-carriers. | 09-03-2009 |
| 20090323606 | UNEQUAL ERROR PROTECTION FOR A MULTICARRIER TRANSMISSION - A method and apparatuses relate to data transmission between at least one first radio station and at least one second radio station in a radio communication system. At least one portion of an available spectrum is allocated for said at least one data transmission, the at least one portion including a number of adjacent sub-carriers; error protection is used for data transmission, wherein the error protecting is distributed in an unequal manner throughout the at least one portion allocated for the at least one data transmission. Data is transmitted upon completion of said error protection. | 12-31-2009 |

| 20100041426 | INTER BASE STATION COMMUNICATION FOR JOINT RESOURCE MANAGEMENT - According to a method for operating a radio communication system, a first radio station decides about the assignment of first radio resources to a user terminal and thereafter assigns the first radio resources to the user terminal. Before deciding about the assignment of the first radio resources to the user terminal, the first radio station transmits information to a second radio station regarding the first radio station's future assignment of the first radio resources. Radio stations carry out the method. | 02-18-2010 |
| 20110063977 | Inter-Network-Nodes Flow Control - A mobile network telecommunication system is provided. The system includes a base station for sending flow control signal for a UE (user equipment) to a core network, the core network being capable of responding to the flow control signal by buffering packet data for the UE, and an interface for transmitting the flow control signal between the base station and the core network. | 03-17-2011 |
| 20110087797 | METHOD AND DEVICE FOR PROCESSING DATA IN A NETWORK COMPONENT AND SYSTEM COMPRISING SUCH A DEVICE - A method, a device and a system are provided for processing data in a first network component comprising the steps of (i) the data is received by the first network component from a second network component; and (ii) the data is processed by a filter function according to which the whole data or a portion of the data is used. | 04-14-2011 |
| 20110110247 | Routing Node and Terminal for an FDD Communication Network and Method for Operating Them - One exemplary aspect of the invention provides a routing node for an FDD communication network, which node has a node receiving apparatus, which is set up in such a manner that it can be used to receive signals from a terminal at a first frequency, and a node transmitting apparatus which is set up in such a manner that it can be used to transmit signals to the terminal at a second frequency. In this case, the routing node is set up in such a manner that it can transmit an indication signal to the terminal, which signal indicates whether the routing node can receive signals at the first frequency at a given point in time. | 05-12-2011 |
| 20110116427 | METHOD AND APPARATUS FOR CONFIGURING MODE TIMERS - Controlling a probability that user equipment is in a power saving mode to adapt the user equipment to characteristics of a shared channel and packet service includes determining a class of the user equipment by comparing at least one data traffic requirement value and a power condition value of the user equipment with predetermined threshold values, and adjusting mode timers according to the determined class of the user equipment depending on the data traffic requirement values and depending on the power condition value of the user equipment. | 05-19-2011 |
