A method of using a reference signal, RS, for a radio link between a base station and a radio device, the method comprising:

• receiving, from the base station, a control message indicative of a scrambling identifier selector for selecting a scrambling identifier associated with the radio link, wherein the received scrambling identifier selector depends on a time index and a link identifier associated with the radio link;
• and
• transmitting to or receiving from the base station over the radio link the RS that is based on a pseudo-random binary sequence, PRBS, at a time according to the time index, wherein the PRBS is generated using a seed value depending on the time index, the scrambling identifier selector and the scrambling identifier selected according to the scrambling identifier selector.

A device for controlling a reference signal, RS, for a radio link between a base station and a radio device, the device comprising at least one processor and a memory, said memory comprising instructions executable by said at least one processor, whereby the first radio device is operative to:

• transmit, to the radio device, a control message indicative of a scrambling identifier selector for selecting a scrambling identifier associated with the radio link, wherein the transmitted scrambling identifier selector depends on a time index and a link identifier associated with the radio link;
• and
• transmit to or receive from the radio device over the radio link the RS that is based on a pseudo-random binary sequence, PRBS, at a time according to the time index, wherein the PRBS is generated using a seed value depending on the time index, the scrambling identifier selector and the scrambling identifier selected according to the scrambling identifier selector.
