摘要： A radio network node in a multi-carrier radio communication system reconfigures mappings of Carrier Indicator Field values (CIF-values) to component carriers. Each CIF-value is mapped to a respective component carrier comprising a respective shared data channel and a downlink control channel that addresses the shared data channel. The reconfiguring comprises maintaining a first mapping between a first CIF-value and a first component carrier. The downlink control channel of the first component carrier carries the first CIF-value and a second CIF-value. The reconfiguring further comprises changing a second mapping of the second CIF-value to a second component carrier. The radio network node sends the changed second mapping to a user equipment (UE) comprised in the multi-carrier radio communication system. The UE receives the reconfigured mappings and reconfigures the UE to use the mappings for communication in the multi-carrier radio communication system.

摘要： 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.

摘要： Methods are disclosed which can be performed by a network node for sending to a wireless device a first synchronization signal and an associated information message, for synchronization of the wireless device with the network node. The network node and the wireless device operate in a wireless communications network. The network node sends the first synchronization signal in N OFDM symbols within a subframe, at least once in a time and frequency position in every one of the N OFDM symbols. N is equal or larger than 2. For each sending of the first synchronization signal, the network node sends an associated information message at a pre-defined time and frequency position in an OFDM symbol. The pre-defined time and frequency position is relative to the time and frequency position of the first synchronization signal. The associated information message is associated with the first synchronization signal.

摘要： The present invention relates to methods and apparatus in a RBS and a UE for reference signal (RS) measurements in an OFDM system, that enable having a configurable RS transmission bandwidth which is smaller than the system bandwidth. This allows for better interference coordination of RS, which in turn improves the UE RS measurements used for different services such as positioning. The RBS retrieves the RS transmission bandwidth, determines a RS measurement bandwidth based on this RS transmission bandwidth, and transmits the determined bandwidth to the UE. The UE receives the RS measurement bandwidth and measures the RS in a bandwidth determined based on the received measurement bandwidth and the UE capability.

In one exemplary embodiment, a method may include scheduling downlink transmissions to a first user terminal on a single downlink component carrier (CC) associated with a primary cell and scheduling downlink transmissions to a second user terminal on multiple downlink CCs or on a downlink CC associated with a non-primary cell. Further, the method may include receiving, on a first set of radio resources, control information associated with the downlink transmissions to the first user terminal. In addition, the method may include receiving, on a second set of radio resources, control information associated with the downlink transmissions to the second user terminal.

摘要： 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.
