The disclosure relates to methods and apparatuses for feedback messaging in a communication system. A station can include into a scheduling information entity an indication of aperiodic feedback messaging on a physical uplink control channel and dynamically send the scheduling information entity with the indication to a communication device configured for periodic feedback messaging to trigger aperiodic feedback messaging by the communication device on the physical uplink control channel. Upon receiving the scheduling information entity the device can determine that it includes the indication and in response to the determining send at least one aperiodic feedback message on the physical uplink control channel.

A method and apparatus for re-interpreting channel state information are provided, which relate generally to wireless communications, and more specifically are directed toward the use of channel state information/channel quality indications in a wireless network. The apparatus includes at least one processor and at least one memory including computer program code. The at least one memory and the computer program code are configured, with the at least one processor, to cause the apparatus to perform at least the following: receive from a user equipment correspondence information that relates channel states of a first set to channel states of a second set (302); receive from the user equipment an indication of at least one channel state of the first set which was measured on a downlink (304); use the received indication of at least one channel state of the first set and the received correspondence information to determine a channel state from the second set (306); and adapt a transmission on a downlink channel for the user equipment using the determined channel state (308).

The present invention proposes a method, including in a communication network area constituted by a plurality of transmission points configured for coordinated transmissions to at least one target, each transmission point being identified by an individual identifier, each transmission point being configured to transmit common reference signals on common channels and dedicated reference signals on dedicated channels to said at least one target device, assigning the respective individual identifier of each transmission point to the common reference signals on the common channels of the respective transmission point, and allocating, to the dedicated reference signals on the dedicated channels of respective plural transmission points, an identifier unrelated to the individual identifiers. Also, corresponding devices are addressed.

A method includes receiving information at a first access node with which a user equipment is associated, said information including timing information of a second access node. The method also includes providing access node information for said user equipment in dependence on said timing information, said access node information defining at least one time period when said user equipment is to at least one of transmit to and receive signals from said at least one of said first and second access node.

This disclosure relates to control of communications by a communication device in a service area. Resources for simultaneous communications via a plurality of antennas in the service area are allocated and information of said allocated resources are sent via a plurality of control channels to the communication device. The communication device receives the plurality of control channels and can communicate simultaneously via the plurality of antennas based on the information.

There is provided a mechanism for conducting a communication between at least one communication network control element such as an eNB and at least one communication element such as a UE wherein a DM RS based communication mode is used. DMRS (scrambling) sequences are generated wherein each DMRS sequence includes a set of calculation parameters being specific for the respective DMRS sequence, wherein the set of calculation parameters is configurable by the eNB during communication. For initializing each of the at least one scrambling sequence before receiving the configuration information, i.e. in an initial phase of the communication, a predetermined default value based on e.g. an UE_ID and being selectable from a set of predetermined default values is used for the set of calculation parameters in each DMRS sequence.

There are provided measures for common control deactivation in carrier aggregation, said measures exemplarily including a configuration of a secondary carrier for carrier aggregation with a primary carrier of a terminal, including a deactivation of a common control for the secondary carrier, an indication of the deactivation of the common control for the secondary carrier via the primary carrier, and a signaling of control information, substituting control information of the deactivated common control, for facilitating selection of or operation on the secondary carrier without the deactivated common control via the primary carrier from a base station to the terminal. Said measures may exemplarily be applied for common control deactivation in carrier aggregation in heterogeneous network environments based on LTE, LTE-Advanced, HSPA and/or UMTS radio access systems.

A spectral arrangement for radio resources is usable for transmitting radio data within a telecommunication network. The spectral arrangement includes (a) a first radio resource usable for transmitting radio data in a first data flow direction, wherein the first data flow direction is either an uplink direction or a downlink direction, (b) a second radio resource usable for transmitting radio data in a second data flow direction, wherein the second data flow direction is opposite to the first data flow direction, (c) a third radio resource usable for transmitting radio data in the second data flow direction and (d) a guard band, which on the frequency scale is located between the first radio resource and the second radio resource such that the first radio resource is separated from the second radio resource Between the second radio resource and the third radio resource there is provided no guard band.
