摘要： An interference randomization method in a user equipment, UE, and a corresponding UE are disclosed. A set of control information bits comprising ACK/NACK bits are encoded to generate encoded control information bit. The encoded control information bits are scrambled to generate scrambled control information bits and the scrambled control information bits are modulated to generate modulated symbols. A physical uplink control channel, PUCCH, ACK/NACK resource index is determined and a first orthogonal sequence index, a second orthogonal sequence index, and a cyclic shift for a demodulation reference signal, DMRS, are determined wherein each of the first orthogonal sequence index, the second orthogonal sequence index, and the cyclic shift is determined based the PUCCH ACK/NACK resource index. The modulated symbols are speaded block-wise using a first orthogonal sequence indicated by the first orthogonal sequence index and a second orthogonal sequence indicated by the second orthogonal sequence index and the cyclic shift to the DMRS are applied. The DMRS and the block-wise spread modulated symbols are transmitted on a PUCCH.
