Abstract

A method in a user equipment for arranging a Physical Uplink Control Channel, PUCCH, transmission to a network node in a telecommunications system is provided. The PUCCH transmission comprises control information for use in downlink carrier transmissions. Furthermore, the control information is Reed-Müller, RM, encoded using at least two RM codewords and transmitted using Alamouti encoded transmit diversity over at least two antenna ports. Also, the control information comprises a first bit or symbol sequence and at least a second bit or symbol sequence. The user equipment arranges the first bit or symbol sequence and the at least second bit or symbol sequence, such that at least two bits or symbols from the first bit or symbol sequence and at least second bit or symbol sequence, that subsequently are Alamouti encoded together, originates from the same RM codeword of the at least two RM codewords. This is performed in order to enable control information encoded using one RM codeword to be processed independently from control information encoded using another RM codeword at the network node. A user equipment, a method in network node and a network node are also provided.
