Abstract:
Control channels can benefit from a search space arrangement. For example, an evolved or enhanced physical downlink control channel (E-PDCCH) in the long term evolution advanced (LTE-A) physical layer can benefit in its design from a search space arrangement. A method can include indicating a control channel search space by a pair of parameters. The pair of parameters can include a physical resource block index and an explicit control channel element index. The method can also include transmitting on the control channel within the search space.
Abstract:
An apparatus and a method are provided, by which at least one virtual antenna port is created which includes a plurality of reference signal ports defined in a physical resource block. Information regarding the at least one virtual antenna port including the definition of the reference signal ports is sent to a user equipment, and reference signals are sent on the plurality of reference signal ports to the user equipment
Abstract:
An apparatus including at least one processing circuitry, and at least one memory for storing instructions to be executed by the processing circuitry, wherein the at least one memory and the instructions are configured to, with the at least one processing circuitry, cause the apparatus at least: to obtain, over a series of times, information related to at least one of spatial properties and frequency properties of a channel used in a directional communication between a communication network control element or function and a communication element, to quantify the information related to at least one of spatial properties and frequency properties into a metric, to track whether the metric is smaller than a first threshold or greater than a second threshold during a predetermined period of time, and to decide to use a first transmission mode or a second transmission mode on the basis of a result of the tracking.
Abstract:
Methods and apparatus for cell aggregation are disclosed. In accordance with one aspect information regarding a predefined maximum number of cells that can be aggregated by a communication device on a single carrier resource is sent by the communication device. Said Information is received by a network node where after control on cell aggregation can be based on the information, and the communication device can support cell aggregation on the single carrier resource up to said maximum number of cells.
Abstract:
A method of configuring a component carrier comprises determining how timings of receiving and/or sending data for at least two aggregated component carriers in at least one time period are related; and setting the timing of receiving and/or sending data for the at least two aggregated component carriers based on the determining.
Abstract:
A fronthaul control plane message comprises three or more control plane sections for channels within a resource element range, at least two of which control plane sections are applicable at least in one of resource elements within the resource element range, and the control plane sections comprise or indicate priority information, based on which one of the control plane sections may be selected to be used in a resource element.
