Abstract: A method and an arrangement in a radio network node for reconfiguring mappings from Carrier Indicator Field-values to component carriers are provided. Each CIF-value is mapped to a respective component carrier comprising a respective shared data channel. Each respective shared data channel corresponds to at least one downlink control channel carrying said each CIF-value. The radio network node reconfigures mappings from CIF-values to component carriers, while at least one mapping of CIF-value to component carrier is maintained. The component carrier of said at least one mapping from CIF-value to component carrier comprises said at least one downlink control channel and a shared data channel corresponding to said at least one downlink control channel. The radio network node sends at least one of the reconfigured mappings from CIF-values to component carriers to the user equipment.

Abstract: Embodiments herein include a method in a user equipment (UE) for transmitting uplink control information in time slots of a subframe over a radio channel to a radio base station. The uplink control information is comprised in a block of bits. The UE maps the block of bits to a sequence of complex valued modulation symbols. The UE block spreads the sequence across Discrete Fourier Transform Spread-Orthogonal Frequency Division Multiplexing (DFTS-OFDM) symbols. This is performed by applying a spreading sequence to the sequence of complex valued modulation symbols, to achieve a block spread sequence of complex valued modulation symbols. The UE further transforms the block-spread sequence, per DFTS-OFDM symbol. This is performed by applying a matrix that depends on a DFTS-OFDM symbol index and/or slot index to the block-spread sequence. The UE also transmits the block spread sequence, as transformed, over the radio channel to the radio base station.

Abstract: A system and method for determining a Physical Uplink Control Channel (PUCCH) power control parameter h(nCQI,nHARQ) for two Carrier Aggregated (CA) PUCCH formats—PUCCH format 3 and channel selection. The value of h(nCQI,nHARQ) may be based on only a linear function of nHARQ for both of the CA PUCCH formats. Based on the CA PUCCH format configured for the User Equipment (UE), the e-Node B (eNB) may instruct the UE to select or apply a specific linear function of nHARQ as a value for the power control parameter h(nCQI,nHARQ), so as to enable the UE to more accurately establish transmit power of its PUCCH signal. Values for another PUCCH power control parameter—?F—PUCCH(F)—are also provided for use with PUCCH format 3. A new offset parameter may be signaled for each PUCCH format that has transmit diversity configured.

Abstract: Methods and arrangements for resource allocation in a telecommunication system in which aggregation of component carriers is applied. The size of the resource allocation field is determined based on the transmission bandwidth of a selection of component carriers. The selection of component carriers comprises the component carrier on which the resource allocation message is monitored and the component carriers which are cross-scheduled from said component carrier. The resource allocation message comprising the resource allocation field with the determined size is transmitted to the user equipment over a particular component carrier of the selection of component carriers. Furthermore, with only one size of the resource allocation field a smaller number of code word sizes needs to be monitored by the UE. This leads to a smaller number of blind decodings performed in the UE.

Abstract: The disclosure relates to methods and devices for performing uplink power control in a radio communication system. An example method comprises a step of receiving, at a user equipment (UE) a transmit power control (TPC) command. The method also comprises, if the UE does not have an uplink transmission scheduled for a subframe associated with the TPC command, a step of accumulating, by the UE, the TPC command with previously received TPC commands based on whether the UE has reached a maximum transmit power or a minimum transmit power in a reference format for a Physical Uplink Shared Channel (PUSCH), Sounding Reference Signal (SRS) or Physical Uplink Control Channel (PUCCH) transmission. Thus the UE is enabled to receive TPC commands while the UE is not transmitting anything in the uplink.

Abstract: A method for processing downlink control information in a mobile terminal capable of receiving multiple component carriers. The mobile terminal receives on a component carrier, downlink control information that includes a bit field allocated for a transmit power control (TPC) command. If the bit field comprises one or more bits that are not used for the TPC command, the mobile terminal interprets the meaning of the bits not used for the TPC command based on an ACK/NACK feedback mode with which the mobile terminal is configured.

Abstract: Example embodiments are directed towards a network node, and corresponding method, for a configuration of scheduling or control timing for a user equipment in a multiple cell communications network.

Abstract: A Level-1 (L1) signaling flag is mapped to unused (invalid) bit sequences in Part 1 of the HS-SCCH—that is, Part 1 bit encodings that are not defined in the UTRAN specifications—and a corresponding L1 command is encoded in Part 2. This allows UE (18) to detect early that the HS-SCCH is pure L1 signaling, and the UE (18) may avoid wasting power by not processing an accompanying HS-PDSCH. Alternatively, in CPC HS-SCCH-less mode, the UE (18) may blind decode the HS PDSCH. In one embodiment, a general DRX mode is defined and controlled via L1 signaling. In one embodiment, a UE (18) acknowledgement improves the L1 signaling accuracy. In one embodiment, a L1 signal and UE (18) acknowledgement protocol are utilized to “ping” a UE (18).

Abstract: A method, User Equipment (UE), and radio base station or NodeB for controlling the downlink transmit power of a Fractional Downlink Physical Control Channel (F-DPCH) in a multi-carrier High-Speed Packet Access (HSPA) system. Single-carrier Transmit Power Control (TPC) commands are modified to support different kinds of multi-carrier scenarios. The UE defines at least one TPC command for adjustment of the transmit power of the F-DPCH of N downlink carriers, the number of TPC commands being equal to or less than N, and transmits the TPC command(s) on at least one of M uplink carriers. The NodeB receives the TPC command(s) and adjusts the transmit power of the F-DPCH of the N downlink carriers based on the received TPC command(s).

Abstract: The present invention relates generally to methods and arrangements for positioning in a wireless communications system. In particular, the present invention relates to improving positioning accuracy. The invention provides methods and arrangements for scheduling positioning subframes for allowing aligning of positioning subframes across a number of cells in order to reduce the interference from data symbols of cells in the neighborhood of a cell serving the UE that is performing positioning measurements. A time instance during which transmission of the positioning subframes is to occur in a wireless communications network is selected. The base stations in the wireless communications network are informed about the selected time instance, whereupon the base stations schedule and transmit the positioning subframes based on the selected time instance, whereby the positioning subframes are aligned throughout the network.
