In particular, the present invention relates to improving positioning accuracy. The invention provides methods and arrangements for scheduling positioning subframes, i.e. low interference 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.

    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 method of wirelessly transmitting control information includes generating control information comprising a plurality of control bits and encoding the control bits using a block code that outputs an encoded bit sequence comprising encoded bits b(0), b(1), . . . , b(19). The control bits are encoded using the block code by generating a linear combination of a plurality of basis sequences. The method also includes dividing the encoded bits into a first group and a second group. The first group includes the encoded bits {b(0), b(1), b(5), b(6), b(8), b(11), b(12), b(14), b(17), b(19)} and the second group includes the encoded bits {b(2), b(3), b(4), b(7), b(9), b(10), b(13), b(15), b(16), b(18)}. Additionally, the method includes transmitting the first group of encoded bits on a first set of carriers and transmitting the second group of encoded bits on a second set of carriers. The second set of carriers have different frequencies from the first set of carriers.
