Abstract
A terminal according to one aspect of the present disclosure includes: a transmitting section that transmits capability information indicating support of update of at least part of radio resource control (RRC) parameters between a serving cell and a non-serving cell; and a control section that assumes, when the capability information is transmitted, different cell radio network identifiers (C-RNTIs) in the serving cell and the non-serving cell. According to one aspect of the present disclosure, a C-RNTI can be appropriately selected.
Claims7
A terminal comprising:
- a transmitter that, when switching between a serving cell and a non-serving cell is performed, transmits, to a base station, capability information indicating support of update of at least part of radio resource control (RRC) parameters;
- and
- a processor that, when the capability information is transmitted, selects, for the non-serving cell, a cell radio network temporary identifier (C-RNTI) which is different from a C-RNTI of the serving cell,
- wherein in response to receiving an indication related to a non-serving cell associated with a quasi-co-location source reference signal (QCL source RS) of a transmission configuration indication state (TCI state), the processor determines that the serving cell is updated to the non-serving cell.
A radio communication method for a terminal, comprising:
- when switching between a serving cell and a non-serving cell is performed, transmitting, to a base station, capability information indicating support of update of at least part of radio resource control (RRC) parameters;
- when the capability information is transmitted, selecting, for the non-serving cell, a cell radio network temporary identifier (C-RNTI) which is different from a C-RNTI of the serving cell;
- and
- in response to receiving an indication related to a non-serving cell associated with a quasi-co-location source reference signal (QCL source RS) of a transmission configuration indication state (TCI state), determining that the serving cell is updated to the non-serving cell.
A base station comprising:
- a receiver that, when switching between a serving cell and a non-serving cell is performed, receives, from a terminal, capability information indicating support of update of at least part of radio resource control (RRC) parameters;
- and
- a processor that, when the capability information is received, selects, for the non-serving cell, a cell radio network temporary identifier (C-RNTI) which is different from a C-RNTI of the serving cell,
- wherein in response to transmitting an indication related to a non-serving cell associated with a quasi-co-location source reference signal (QCL source RS) of a transmission configuration indication state (TCI state), the serving cell is updated to the non-serving cell.
A system comprising a terminal and a base station, wherein
- the terminal comprises:
- a transmitter that, when switching between a serving cell and a non-serving cell is performed, transmits, to the base station, capability information indicating support of update of at least part of radio resource control (RRC) parameters;
- and
- a processor that, when the capability information is transmitted, selects, for the non-serving cell, a cell radio network temporary identifier (C-RNTI) which is different from a C-RNTI of the serving cell,
- wherein in response to receiving an indication related to a non-serving cell associated with a quasi-co-location source reference signal (QCL source RS) of a transmission configuration indication state (TCI state), the processor determines that the serving cell is updated to the non-serving cell, and
- the base station comprises:
- a receiver that receives the capability information from the terminal.
