TERMINAL DEVICE AND BASE STATION DEVICE

WIPO Patent Application WO/2024/062952

A1

The present invention comprises a reception unit that receives a first PDCCH in which first DCI is disposed, a second PDCCH in which second DCI is disposed, and a PDSCH that is scheduled according to the second DCI. A PDSCH-MTRP method is set to be applied for the purpose of the PDSCH. The PDSCH-MTRP method includes some or all of an SFN method, an FDM method, a TDM method, and an SDM method. The first DCI indicates a first TCI state and a second TCI state. Whether one or both of the first TCI state and the second TCI state is to be applied to the PDSCH is determined on the basis of a higher-layer parameter. If one from among the first TCI state and the second TCI state is to be applied to the PDSCH, then the PDSCH-MTRP method is not applied to the PDSCH. If both the first TCI state and the second TCI state are to be applied to the PDSCH, then the PDSCH-MTRP method is applied to the PDSCH.
