Abstract  Abstract

Disclosed is a user equipment (10) for transmitting uplink control information in time slots in a sub-frame over a radio channel to a radio base station (12). The radio channel is arranged to carry uplink control information and the uplink control information is comprised in a block of bits. The user equipment (10) includes a mapping circuit (213) configured to map the block of bits to a sequence of complex valued modulation symbols. A block spreading circuit (214) is configured to block spread the sequence of complex valued modulation symbols across Discrete Fourier Transform Spread - Orthogonal Frequency Division Multiplexing DFTS-OFDM symbols by applying a spreading sequence to the sequence of complex valued modulation symbols. The result of this is to achieve a block spread sequence of complex valued modulation symbols. A transforming circuit (215) is configured to transform per DFTS-OFDM symbol the block-spread sequence of complex valued modulation symbols by applying a matrix with matrix elements. The matrix elements are cyclically shifted depending on a DFTS-OFDM symbol index and/or slot index to the block-spread sequence of complex valued modulation symbols. A transmitter (217) is configured to transmit the block spread sequence of complex valued modulation symbols that has been transformed over the radio channel to the radio base station (12).
