USER DEVICE, BASE STATION DEVICE, AND COMMUNICATION METHOD

WIPO Patent Application WO/2021/029023

A1

This user device comprises: a reception unit which receives information about a transmission setting state for a downlink shared channel from a base station device; a control unit which individually applies, on the basis of the information about the transmission setting state, a QCL-related setting to a downlink shared channel transmitted from a first TRP or panel or from a second TRP or panel; and a communication unit which performs communication via the downlink shared channel to which the QCL-related setting is applied individually. The information about the transmission setting state includes RRC signaling, MAC signaling, and DCI. The RRC signaling includes a plurality of transmission setting states. The MAC signaling enables, among the plurality of transmission setting states, a first number of transmission setting states to be applied to the second TRP or panel. The DCI includes a field for designating, from among the first number of transmission setting states having been enabled, a transmission setting state for a downlink shared channel transmitted from the second TRP or panel.
