    Abstract: A node (1120) of a wireless network (1130) transmits (210) information to a user equipment (1110) over an aggregated earlier that includes a primary carrier having a first set of primary carrier time/frequency resources and a secondary carrier having a second set of secondary carrier time/frequency resources. Synchronization signals and/or reference symbols are transmitted (220) to the user equipment on the secondary carrier less often than on the primary carrier. An indication of when and/or how often the synchronization signals and/or reference symbols will be transmitted to the user equipment on the secondary carrier may also be transmitted (230) to the user equipment over the primary carrier. By transmitting synchronization signals and/or reference symbols to the user equipment on the secondary carrier less often than on the primary carrier, resources of the secondary carrier may be conserved, energy efficiency of the secondary carrier may be increased, and/or interference with other cells may be reduced or prevented.

    Abstract: Embodiments herein relate to a method in a user equipment (10) for transmitting uplink control information in time slots in a subframe over a radio channel to a radio base station. The radio channel is arranged to carry uplink control information and the user equipment and radio base station are comprised in a radio communications network. The uplink control information is comprised in a block of bits. The user equipment maps the block of bits to a sequence of complex valued modulation symbols. The user equipment also block spreads the sequence of complex valued modulation symbols 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 user equipment further transforms the block-spread sequence of complex valued modulation symbols 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 of complex valued modulation symbols. The user equipment also transmits the block spread sequence of complex valued modulation symbols that has been transformed over the radio channel to the radio base station.

    Abstract: A method and an arrangement 400 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 130 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 130 sends at least one of the reconfigured mappings from CIF-values to component carriers to the user equipment 120.

    Abstract: 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 of OFDM symbols within a subframe, at least once in a time and frequency position in every one of the N of OFDM symbols, wherein 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. WO 2015/080646 PCT/SE2014/051 144
