Abstract: Automatically adjust the size of a Physical Uplink Control Channel, PUCCH, of an uplink communication subframe. In a particular embodiment, the size of a semi-static region of the PUCCH is adjusted. The adjustment is based on a utilization factor of the PUCCH over a time period. The adjustment can also be based on the connection factor (connections between the wireless terminals and the cell) and/or based on the utilization factor of a PUSCH (Physical Uplink Shared Channel). The result is an efficient resource utilization on the PUCCH, and a properly dimensioned PUCCH region.

Abstract: An Uplink control channel resource Management Module (120, 130), referred to as “UMM”, and a method in the UMM for assigning, to a radio network node 110, uplink control channel resources, referred to as “UCCHR”, for use in a uplink control channel between the radio network node (110) and a communication device (160) are provided. The UMM obtains (210) resource allocation information, referred to as “RAI”, and generates (220) a resource allocation command, referred to as “RAC”, based on the RAI. The RAC indicates UCCHR to be used by the radio network node. Furthermore, the UMM provides (230) the RAC to the radio network node (110). Related methods and nodes to enable the UMM to assign UCCHR are also provided.

Abstract: A method in a wireless network containing a first node and an adjacent second node for determining an uplink received power target value of the second node to be used by a user equipment which is to be served by the second node includes establishing the uplink received power target value of the first node. The method also includes obtaining the downlink power capacity of the first node and obtaining the downlink power capacity of the second node. Additionally, the method includes calculating the difference in downlink power capacity between the first node and the second node and determining the uplink received power target value of the second node based on the calculated difference in downlink power capacity between the nodes and the established uplink received power target value of the first node.

Abstract: A relay node identified by a unique relay node identifier relays communications between a donor base station and one or more user terminals. The donor base station acquires the relay node identifier during a relay node attach procedure from where the relay node or another node in the core network (e.g., mobile management entity). The donor base station may use the relay node identifier to retrieve configuration information for the relay node. The configuration information may be used to configure the relay node, to perform radio resource management functions, and/or to monitor the performance of the relay node.

Abstract: The present invention relates to a method and apparatus for user terminal and bearer identification that reduces the overhead for LTE relaying (layer 2 and layer 3), which will save radio resources on the backhaul link. Reduction in overhead is achieved by providing a more efficient mechanism for user terminal and bearer identification as compared to using GTP-u and associated UDP/IP headers.

Abstract: The present invention provides a method and a radio base station (4) which actively monitor the error rate for messages transmitted over an uplink control channel between the radio base station (4) and one or more mobile terminals (6). The distribution of messages transmitted on the uplink control channel is then adapted in dependence on the measured error rate.

Abstract: Uplink transmission scheduling requests (SRs) may be prohibited for a lower priority data flow, logical channel group (e.g., VoIP configured with semi-persistent resource allocation), or other grouping but may still be triggered for higher priority traffic (e.g., data connected to a signaling radio bearer (SRB)). More efficient scheduling is also achieved by allowing an uplink transmission scheduler to distinguish between different priority flows or groups (e.g., LCGs) without a buffer status report (BSR), As a result, when a semi-persistent resource is scheled for the lower priority data, there is less delay for high priority data while eliminating uplink and downlink control signaling, i.e., fewer scheduling requests (SRs) and uplink grants, for the lower priority data.

Abstract: A method for power measurements in a cellular communication system comprises receiving measurement configuration orders. Operation of a power meter is controlled in dependence on the measurement configuration orders. Reference signal received powers are measured. A measurement report is compiled and transmitted. The measurement configuration orders comprise cell status information associated with neighboring cells and measurement instructions that are dependent of the cell status of respective cell. The cell status information comprises information about whether the neighboring cell is of a different type than the serving cell. Controlling of the operation of the power meter and/or compiling of the measurement report is performed in dependence on the cell status of the neighboring cell. A method for handover based on such measurement reports is also disclosed as well as Node Bs and user equipments configured to perform such methods.

Abstract: The present invention relates to allowing configuring CSI reporting (step S-224, 310) on radio resources that are allocated over a plurality of sub frames on Physical Uplink Shared Channel (PUSCH). Allocation of said radio resources (steps S-202, 404) can be performed by semi-persistent allocation or by using Transmission Time Interval (TTI) bundling. By using either semi-persistent scheduling or TTI-bundling as decided by an eNB (104, 204, 600) the UE (102, 202, 500) can be configured to report CSI (step S-224, 310) for a plurality of UL transmissions. By allocating radio resources by using semi-persistent scheduling, the signaling overhead, which can be substantial for dynamic scheduling of radio resources, decreases. By using TTI-bundling the coverage of the CSI-reports increases.

Abstract: Method and arrangement in a relay node, for selecting communication mode. The relay node is configured to communicate with a base station via a donor antenna over a first link and to communicate with a user equipment via a coverage antenna over a second link. The method comprises obtaining an isolation value, based on the radio wave isolation between the relay donor antenna and the relay coverage antenna. The obtained isolation value is compared with an isolation threshold level value. The relay node is configured to communicate in full duplex mode if the obtained isolation value exceeds the isolation threshold level value, otherwise in half duplex mode. Information concerning the configured duplex mode of the relay node is transmitted to the base station. Also a method and arrangement in a base station is described.

Abstract: Method and arrangement in a base station for adjusting a channel quality indicator value of a wireless transmission between the base station and a user equipment. The base station, the user equipment and a relay node are comprised in a multi-hop wireless communication system and adapted to intercommunicate in a first transmission mode and a second transmission mode. The method comprises sending a radio signal to be received by the user equipment, obtaining a measurement of the channel quality indicator value, determining if the transmission mode of the sent radio signal is different from the transmission mode of the obtained channel quality indicator value measurement, and adding a channel quality indicator offset value to the channel quality indicator value, if the transmission mode of the relay node is determined to be the first transmission mode while the channel quality indicator was measured and obtained in the second transmission mode.

Abstract: 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.
