20140335878 | SELECTION OF A SECONDARY COMPONENT CARRIER BASED ON INTERFERENCE INFORMATION - A method includes selecting a candidate component carrier for a cell and determining if said candidate component carrier is to be used in said cell in dependence on information indicating activity in at least one of said cell and another cell using said candidate component carrier. | 11-13-2014 |
20140348105 | Signaling of Uplink Scheduling Information in Case of Carrier Aggregation - An apparatus and a method is provided, by which data is sent to and/or received from a first network control node and at least one second network control node by a carrier aggregation, uplink scheduling information is established and sending of the uplink scheduling information is managed individually for the first network control node and the at least one second network control node. | 11-27-2014 |
20140349664 | Methods and Apparati Which May Reuse Resources in Neighboring Cells - A method including configuring one or more reference signals and/or channels in a carrier bandwidth including one or more physical resource units; and causing information on the configuration of said one or more reference signals and/or channels to be provided to another base station using a same or overlapping carrier bandwidth. | 11-27-2014 |
20140362707 | Selecting Between Normal And Virtual Dual Layer ACK/NACK - An allocation of downlink resources is received, which are monitored on I layers for data. A resource-specific bit (ACK/NACK) is generated for each of those resources. From a pattern of those resources is selected an algorithm from among a first algorithm that bundles them in a first mode and a second algorithm that bundles them in a second mode. The selected algorithm is used on the generated resource-specific bits that correspond to the downlink resources, bundled according to the selected mode, to generate I reply bits which are then transmitted. At the network side a NACK reply bit is received, based on a pattern of the allocated downlink resources, a first algorithm that bundles them in a first mode or a second algorithm that bundles them in a second mode is selected. A bundling window and layer combination are determined from the selected algorithm, which gives the resource for retransmitting the NACK'd data. | 12-11-2014 |
20150009898 | Configuration of Carrier-Related Reference Signal Transmission - There are provided measures for configuration of carrier-related reference signal transmission. Such measures exemplarily include setting of a transmission mode for reference signal transmission on a carrier out of at least a long-cycle discontinuous transmission mode and a short-cycle discontinuous transmission mode, said long-cycle discontinuous transmission mode having a longer transmission discontinuity period than the short-cycle discontinuous transmission mode, and configuration of a transmission of at least one reference signal on the carrier according to the set transmission mode. The transmission mode setting may for example be based on at least one of an activation state of the carrier as serving cell and/or secondary cell and/or measurement object cell and a period of radio resource management measurement on the carrier. | 01-08-2015 |
