| 20080280611 | Smooth Hard Handover Method, Mobile Station and Base Station Adapted For The Method - The present invention relates to a cellular radio communications system and especially a method, a mobile station and a base station for a smooth hard handover. The smooth hard handover includes preparing radio links in selected base stations for potential communication with a mobile station. This is similar to selecting base stations for the active set in the prior art soft handover. A difference is though that just one radio link is actively used for transmission. The handover from the active to a prepared radio link is quick and safe, as compared to conventional hard handover, because of the preparation, while requiring a less complex system architecture then the conventional soft handover. The smooth hard handover can replace the soft handover. | 11-13-2008 |
| 20090005058 | Dynamic Inter-Cell Channel Sharing - A mechanism to share channels between cells dynamically and without simultaneous allocation of the same channel by more than one access point achieved by a method for a dynamic inter-cell channel sharing for a first access point in a radio access network, the first access point being associated with a first cell of a number of cells within the radio access network, the first access point being adapted to connecting at least one first user equipment being situated in the first cell, to a network infrastructure, comprising the steps of: receiving from the at least one first user equipment a report indicating whether a specific channel is used in a second adjacent cell of said number of cells, the report being based on a first information sent from at least one second access point, the information indicating whether a specific channel is used in the second adjacent cell. | 01-01-2009 |
| 20090325580 | Method and Arrangement in a Telecommunication System - A method is described of assigning to a user equipment one or more idle gap patterns in uplink and/or downlink communications between the user equipment and a radio base station, to allow the user equipment to perform downlink measurements on neighbour cells during the idle gaps. The method comprises defining a pre-assigned idle gap pattern; and modifying the pre-assigned idle gap pattern on the basis of one or more short commands sent between the user equipment and the radio base station. | 12-31-2009 |
| 20100110958 | METHOD FOR CONTENT SYNCHRONIZATION WHEN BROADCASTING DATA IN A WIRELESS NETWORK - The present invention relates to an arrangement and method for content synchronization when broadcasting data from an infrastructure node in a communication network. The arrangement comprises a receiver receiving data sequences and a transmitter for transmitting data sequences. Each data sequence has a data size and comprises a sequence number (SN). The arrangement further comprises a processing arrangement configured to add byte numbered sequence numbers to said data sequences passed between layers in a protocol stack for transmission to a transceiver station. | 05-06-2010 |

| 20100197308 | Handover Using Dedicated Resources Reserved For A Limited Time Interval - A method and arrangement for handover wherein the handover resource (the dedicated random access preamble) is reserved by the target radio base station (RBS) for a limited period of time, thus increasing the handover efficiency and thereby allowing random access preambles to be used for initial access to a larger extent. The information about the reserved time interval is sent to the UE in the handover command message by means of a frame number offset between the source RBS and the target RBS. The UE uses the information to calculate when to send its synchronisation message to the target RBS. The frame number offset is calculated either by source RBS or by target RBS. | 08-05-2010 |
| 20100216471 | Link Layer Control Protocol Implementation - A radio base station suitable for performing a handover operation for a LTE-variant of a radio access network comprises a transceiver and a status report requester. The transceiver is configured to facilitate wireless transmission between the radio base station and a wireless terminal over an air interface, including transmission of a radio link bearer for the connection over a downlink from the radio base station to the wireless terminal. The status report requester is configured to determine, according to one or more pre-defined criteria, whether to request from the wireless terminal a status report for a radio bearer prior to the radio base station transferring user data for the connection to another radio base station in conjunction with a handover. | 08-26-2010 |
| 20100232340 | Method of Transmitting MBMS Data in an E-UTRAN-System - In an Evolved Universal Terrestrial Radio Access Network (E-UTRAN) system Multimedia Broadcast Multicast Service (MBMS) data is transmitted as layered data together with control information comprising information enabling a User Equipment to reconstruct the layered MBMS data. | 09-16-2010 |

| 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 |
| 20110075633 | Data Forwarding During Handover in a Self-Backhauled Cell - A method is implemented in an anchor eNodeB of a network, where the anchor eNodeB communicates with a self-backhauled eNodeB via a radio interface and where the network further includes another eNodeB. 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 |
