Abstract
Systems and methods for determining Transmission Configuration Indication (TCI) states for Aperiodic (AP) Channel State Information Reference Signals (CSI-RSs) overlapping with downlink transmissions are provided. In some embodiments, a method performed by a wireless device includes: receiving AP CSI-RSs in the same symbols as downlink transmissions scheduled by a DCI with two TCI states indicated in DCI; receiving triggering of the one or more AP CSI-RS with scheduling offset between the last symbol of the PDCCH carrying the triggering DCI and the first symbol of the AP CSI-RS resources, where the scheduling offset is smaller than a wireless device reported threshold; and determining that the downlink transmission is scheduled according to a scheme where different sets of layers of the downlink transmission are received with different TCI states. In some embodiments, the wireless device applies a QCL assumption for a PDSCH transmission occasion when receiving the AP CSI-RS.
