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.
