Inventors include Matsumura, Yuki; Nagata, Satoshi; Wang, Jing; and Hou, Xiaolin.
The application for the patent was published on August 14, 2026, under issue no. 33/2026.
Abstract: The present invention discloses a terminal, a base station, a system, and a radio communication method for a terminal. A terminal comprising: a processor that, when a single transmission configuration indicator (TCI) state is configured, by radio resource control (RRC) signaling, for a control resource set (CORESET) other than a CORESET with an index of 0, assumes that the single TCI state corresponds to the CORESET other than the CORESET with the index of 0, and when a plurality of TCI states is configured, by RRC signaling, for the CORESET other than the CORESET with the index 0 in an RRC reconfiguration, in response not to activate any one of the plurality of TCI states by a Medium Access Control Control Element (MAC CE) activation command for the CORESET other than the CORESET with the index of 0, assumes that a demodulation reference signal (DMRS) antenna port associated with a physical downlink control channel (PDCCH) is quasi co-located with a synchronization signal block identified during a random access procedure during the RRC reconfiguration or a channel state information reference signal identified during the random access procedure during the RRC reconfiguration; and a receiver that receives the PDCCH, wherein, when the single TCI state is configured for the CORESET other than the CORESET with the index of 0, the processor assumes that the DMRS antenna port associated with the PDCCH is quasi co-located with the single TCI state and the receiver receives the PDCCH.
