Two types of uplink reference signals are supported:

– Demodulation reference signal, associated with transmission of PUSCH or (S)PUCCH

– Sounding reference signal, not associated with transmission of PUSCH or (S)PUCCH

The same set of base sequences is used for demodulation and sounding reference signals.
