A first and second communication device and respective method thereby are provided for performing a radio transmission. The method performed by the first communication device comprises generating a base sequence, and replicating the base sequence per each RS panned by an OCC. The method further comprises applying, to the base sequences, an individual RS-specific circular rotation, wherein each rotated base sequence corresponds to an RS. The method also comprises multiplying each RS with a respective value of the OCC, and mapping each frequency domain RS to a subframe. Still further, the method comprises converting the subframe to a time domain; and transmitting the subframe to the second communication device. |

1. A method performed by a first communication device for performing a radio transmission to a second communication device, the method comprising:
generating a base sequence, replicating the base sequence per each Reference Signal, RS, spanned by an Orthogonal Cover Code, OCC, applying, to the base sequences, an individual RS-specific circular rotation, wherein each rotated base sequence corresponds to an RS, multiplying each RS with respective value of the OCC, mapping each frequency domain RS to a subframe, converting the subframe to a time domain, and transmitting the subframe to the second communication device. |
