Terminal and radio communication method
A terminal according to one aspect of the present disclosure includes a receiving section that receives a Physical Downlink Control Channel (PDCCH) configuration with a maximum number of control resource sets (CORESETs) exceeding 3, and a control section that assumes that a transmission configuration indication state (TCI state) for a PDCCH with respect to the CORESETs is designated on the basis of a Medium Access Control Control Element (MAC CE). According to one aspect of the present disclosure, it is possible to perform DL communication preferably even when multiple panels/TRPs are used.
1. A terminal comprising:
a receiver that receives a Physical Downlink Control Channel (PDCCH) configuration with a number of Control Resource Sets (CORESETs) exceeding 3; and
a processor that controls, based on a Transmission Configuration Indication state (TCI state) indication for a User Equipment (UE)-specific PDCCH Medium Access Control Control Element (MAC CE) (TCI State Indication for UE-specific PDCCH MAC CE) defined in the Third Generation Partnership Project (3GPP) Release 15, Quasi-Co-Location (QCL) assumption for a DeModulation Reference Signal (DMRS) antenna port associated with PDCCH in a CORESET, wherein a maximum number of CORESETs per serving cell is 16.
2. The terminal according to claim 1 , wherein CORESET Identifier (ID) indexing is common to all CORESET groups.
3. A radio communication method for a terminal, comprising:
receiving a Physical Downlink Control Channel (PDCCH) configuration with a number of Control Resource Sets (CORESETs) exceeding 3; and
controlling, based on a Transmission Configuration Indication state (TCI state) indication for a User Equipment (UE)-specific PDCCH Medium Access Control Control Element (MAC CE) (TCI State Indication for UE-specific PDCCH MAC CE) defined in the Third Generation Partnership Project (3GPP) Release 15, Quasi-Co-Location (QCL) assumption for a DeModulation Reference Signal (DMRS) antenna port associated with PDCCH in a CORESET, wherein a maximum number of CORESETs per serving cell is 16.
4. A system comprising a terminal and a base station, wherein
the terminal comprises:
a receiver that receives a Physical Downlink Control Channel (PDCCH) configuration with a number of Control Resource Sets (CORESETs) exceeding 3; and
a processor that controls, based on a Transmission Configuration Indication state (TCI state) indication for a User Equipment (UE)-specific PDCCH Medium Access Control Control Element (MAC CE) (TCI State Indication for UE-specific PDCCH MAC CE) defined in the Third Generation Partnership Project (3GPP) Release 15, Quasi-Co-Location (QCL) assumption for a DeModulation Reference Signal (DMRS) antenna port associated with PDCCH in a CORESET, wherein a maximum number of CORESETs per serving cell is 16, and
the base station comprises:
a transmitter that transmits the PDCCH configuration to the terminal.
