摘要： A terminal according to an aspect of the present disclosure includes: a receiving section that receives information relating to a physical downlink shared channel (PDSCH); and a control section that uses, when medium access control (MAC) control element (CE) is indicated and the information satisfies an applicable condition, a specific transmission configuration indication (TCI) state based on the MAC CE for receiving the PDSCH instead of a TCI state indicated for the PDSCH. According to an aspect of the present disclosure, QCL parameters can be appropriately determined.

摘要： A terminal according to an aspect of the present disclosure includes: a receiving section that receives at least one of first information relating to a physical downlink shared channel (PDSCH) and second information relating to an uplink signal; and a control section that uses, when the first information satisfies a first condition, a first Quasi-Co-Location (QCL) parameter for receiving the PDSCH, instead of a QCL parameter indicated for the PDSCH, and uses, when the second information satisfies a second condition, a second QCL parameter for transmitting the uplink signal, instead of a QCL parameter indicated for the uplink signal, in which the first QCL parameter and the second QCL parameter are equal. According to an aspect of the present disclosure, QCL parameters can be appropriately determined.
