| 20080232258 | Method and Arragement for Advanced Routing Metrics in Multihop Networks - The inventors have envisioned a multihop network scenario in which nodes are equipped with advanced multi-antenna arrangements, and recognized the advantage of exploring the presence of such advanced antenna arrangements in multihop network nodes for the specific purpose of determining link cost for routing in the network. A basic idea of the invention is therefore to determine link cost for a wireless link between a pair of nodes in the network based on multi-channel characteristics between the nodes, where at least one of the nodes is configured for operation with multiple antennas to provide for multiple channels. These multi-channel characteristics may for example be determined based on explicit channel matrix estimation and/or the number of transmit and receive antennas or other information on the antenna capabilities of the involved nodes. The determined link cost information may subsequently be used together with additional routing cost information for route determination, and packet forwarding. | 09-25-2008 |
| 20090010269 | Method And Apparatus For Routing Packets - Packets may be routed in a heterogeneous communications network as follows: for a set of packets comprising at least one packet to be transmitted from a sending node, said sending node being able to handle communication according to at least two access technologies, —selecting in a selection unit in the sending node an access technology for use when transmitting the set of packets, —selecting a receiving node in the network to which to transmit the set of packets among nodes in the network that are able to handle said selected access technology—transmitting the set of packets to the selected receiving node using the selected access technology. Alternatively, a set of packets may be transmitted to one or more nodes using at least two different access technologies. Depending on the transmission quality, one node may be selected to forward the set of packets. | 01-08-2009 |
| 20090109902 | METHOD AND ARRANGEMENT IN A COMMUNICATIONS SYSTEM - The object of the present invention is to provide a mechanism for a more efficient carrier search. The object is achieved by a method for sending a signal in a first node. The first node communicates with a second node via radio communication, which radio communication is performed by multi carrier transmission. The first node uses a carrier, being associated with a frequency range. The method comprises the step of transmitting an end-marker signal within or close to the frequency range. The end-marker signal is intended to be received and used by the second node for identifying the frequency range of the used carrier. | 04-30-2009 |
| 20090231989 | Method and Apparatus for Interference Reduction - A method and apparatus for reducing interference caused by an interfering signal are disclosed for use in an access node, such as a base station, communicating with at least one mobile terminal in a wireless network, the method comprising the following steps: receiving information related to at least one data packet that is to be transmitted by a second access node to at least a second mobile terminal, receiving time-frequency information about the point in time when the at least one data packet will be transmitted from the second access node to the second mobile terminal, estimating the interfering signal based on the at least one data packet, cancelling interference based on the estimated interference signal at the point in time. This facilitates interference cancellation, especially in a network using distributed RRM. | 09-17-2009 |
| 20090268662 | Method and Arrangement for Bi-Directional Relating in Wireless Communication Systems - The present invention relates to methods and arrangements in a relaying radio node and/or in a sending/receiving radio node, adapted for use in a relaying communication system. The relaying node is in bidirectional communication with at least a first and a second sending/receiving radio node, and the relaying radio node receives at least a first signal carrying at least first data and a second signal carrying at least second data. The relaying node generates a reduced representation of at least the first and second signal, with a reduced information content as compared to the first and second data, by a joint non-linearly encoding operation, and transmits the reduced representation to at least the first and the second communication node. The first and second sending/receiving node can extract data from the reduced representation by a non-linear decoding operation using stored a priori information. | 10-29-2009 |
| 20100074177 | Exchange of Information in a Communication Network - A portable node capable of forming ad hoc networks with other nodes is disclosed, as well as a method of transferring at least a first and a second information entity (e.g. files) from a first node to other nodes in an ad hoc network. At least the first and the second information entities are jointly encoded, in the first node, into a composite information entity) in a manner so that the composite information entity can be decoded by use of at least the first information entity or the second information entity. The composite information entity is subsequently transmitted. | 03-25-2010 |
| 20100111069 | SYSTEM AND METHOD OF DOWNLINKING DATA TO AN UNSYNCHRONIZED USER EQUIPMENT IN A TELECOMMUNICATIONS NETWORK - A system, method and node of downlinking transmissions to an unsynchronized UE in a telecommunications network. The method begins by a node in the network requesting synchronization of the UE with the network. A first transmission of data is sent from the node to the UE prior to synchronization of the UE. The UE then synchronizes with the network by the UE performing a Random Access procedure with the node, thereby triggering a time alignment command from the node to the UE to synchronize the UE with the network. A second transmission of data is then sent from the node to the UE after the UE is synchronized. A response feedback message is sent to the node from the UE. The message is a cumulative feedback message of the first transmission of data and the second transmission of data. Thus, data may be transmitted prior to synchronization of the UE. | 05-06-2010 |

| 20110044279 | Self-Backhauling in LTE - A method implemented in an anchor base station configured performing a proxy operation at an anchor base station in which the anchor base station acts as a proxy between a second S-GW or an MME node and a self-backhauled base station. The method includes receiving a data packet destined for the user equipment and mapping the received data packet from an incoming General Packet Radio Service (GPRS) Tunneling Protocol (GTP) tunnel to an outgoing GTP tunnel. The method also includes receiving a control message and modifying elements of the control message while copying other elements in the control message and forwarding the control message between the self-backhauled base station and the second S-GW or MME node. | 02-24-2011 |

The method includes determining whether a user equipment (UE) is being handed off from the first self-backhauled eNodeB to the other eNodeB. The determining is based on: receiving ( | 03-31-2011 |
