Zusammenfassung:	A method, system and apparatus are disclosed. According to some embodiments, a network node is provided which is configured to communicate with a wireless device using at least one of a plurality of transmission and reception points, TRPs. The network node includes processing circuitry configured to indicate to the wireless device a first downlink reference signal, DL RS, of a plurality of downlink reference signals, DL RSs, to use for deriving an uplink, UL, transmission parameter for an UL transmission, each of the plurality of DL RSs being associated with a respective one of the plurality of TRPs. The processing circuitry is further configured to receive the UL transmission, the UL transmission being based on the derived UL transmission parameter.
