20090010364 | Parameter estimation for adaptive antenna system - There is proposed a technique for determining parameters, especially channel estimation, in the receiver of a communication system utilizing adaptive antenna techniques. The technique uses information transmitted in the antenna signals and in the beam signals to determine the parameters. | 01-08-2009 |
20090203405 | Data transmission method, base station and user transceiver - A multicarrier data transmission method and a base station ( | 08-13-2009 |
20090279529 | Synchronization in Mobile Communication System - A solution to overcome synchronization problems related to a scenario where multiple radio access networks utilize a shared frequency band in a radio communication environment is provided. The radio access networks are synchronized to a common synchronization source which may be a synchronization signal broadcasted by another radio system. The synchronization source is selected from a predetermined set of synchronization signals according to the availability of the synchronization signals for transmitters of the radio access networks. | 11-12-2009 |
20110194485 | Control Signaling in System Supporting Relayed Connections - The present invention presents a solution for controlling data transmission with respect to relayed communication links in a cell of a cellular telecommunication system. A first connection is established as a relayed communication link between a first terminal device and a serving base station through a second terminal device operating as a relay terminal for the relayed communication link, and a second connection is established between the second terminal device and the serving base station. Control messages defining dynamic radio resource allocation for both first connection and second connection are used in signaling exchanged between the serving base station and the relay terminal. | 08-11-2011 |
20110194526 | Apparatuses, System, Methods, and Computer Program Products for Network Control - The invention is related to an apparatus including a receiver configured to receive communications from a control node of the macro cell in which the apparatus is located, the communications including system information about operation and maintenance support services the control node is able to provide and/or identity information of the control node; and a generator configured to generate messages including identity information of the apparatus, radio environment information, status information on connections to a core network and/or information on capabilities of the apparatus. | 08-11-2011 |
20110230198 | Apparatus and Method - An apparatus and a method are provided. The provided solution includes determining at least one sub cell specific spectrum load characteristic by an apparatus serving a sub cell; receiving neighbor cell information from an apparatus serving a cell and transmitting the at least one spectrum characteristic to the apparatus serving a cell. | 09-22-2011 |
20110258327 | D2D Communications Considering Different Network Operators - There is stored a database of registration information associating UEs with cells under control of different network operators. In response to a inquiry from a first network operator that a first UE desires direct communications with a second UE, the registration information is used to coordinate between the first network operator and the second network operator to facilitate establishment of a direct communication link between the first UE and the second UE. In various embodiments the facilitating is enhancing the inquiry/page by adding a cell ID of the first UE's cell and adding pre-allocated radio resources in the first UE's cell for use by the second UE in responding to the page, and determining a single network which is not highly loaded and which can allocate resources for the D2D communications and directing one or both UEs to that single network. | 10-20-2011 |
20130337823 | RADIO RESOURCE ALLOCATION MECHANISM - A cellular communication system comprising a plurality of user equipment and a network infrastructure. Radio resource of the plurality of cells is divided into more than one radio resource groups. A network infrastructure element detects a requirement of radio resource allocation for a user equipment and determines effective interference to be generated by the required radio resource to a defined group of neighbouring cells. User equipment is allocated a radio resource from one of the radio resource groups on the basis of the determined effective interference to be generated to the defined group of neighbouring cells. Inter-cell interference decreases and the throughput of the cellular system increases, but the exchange of physical layer information is not increased. | 12-19-2013 |
