  • Publication number: 20250038825
    Abstract: According to an aspect, there is provided an apparatus. The apparatus causes transmitting, by a terminal device, a first message comprising a capability value set index and a synchronization signal block resource index, SSBRI, or a channel state information reference signal resource index, CRI. The capability value set index is associated with a sounding reference signal, SRS, resource set. The apparatus causes the terminal device to receive a second message defining a transmission configuration indication, TCI, state comprising a quasi co-location, QCL, -TypeD reference signal corresponding to the SSBRI or CRI or being quasi co-located in terms of QCL-TypeD with a reference signal corresponding to the SSBRI or CRI. The apparatus causes the terminal device to active or indicate the TCI state. If the SRS resource set is different from an active SRS resource set, the apparatus applies a pre-defined latency time between application and expected triggering of the SRS resource set.
