Abstract
A terminal according to one aspect of the present disclosure includes a receiving section that receives a synchronization signal block of a non-serving cell, and a control section that determines a transmission configuration indication (TCI) state of a demodulation reference signal for a physical downlink shared channel or a physical downlink control channel of a serving cell, based on the synchronization signal block of the non-serving cell. According to one aspect of the present disclosure, communication overhead can be suppressed in inter-cell mobility.
Claims6
A terminal comprising:
- a receiver that receives a synchronization signal block (SSB) of a non-serving cell;
- and
- a processor that determines that a transmission configuration indication (TCI) state of a reference signal indicates a specific quasi co-location (QCL) type with the SSB of the non-serving cell,
- wherein the receiver receives a serving cell configuration in which a serving cell and the non-serving cell have same uplink and downlink bandwidth part (BWP) configurations and receives the serving cell configuration in which the serving cell and the non-serving cell have different SSB configurations, and
- inter-cell multi-transmission/Reception Point (TRP) operation is configured for the terminal.
A radio communication method for a terminal, comprising:
- receiving a synchronization signal block (SSB) of a non-serving cell;
- determining that a transmission configuration indication (TCI) state of a reference signal indicates a specific quasi co-location (QCL) type with the SSB of the non-serving cell;
- and
- receiving a serving cell configuration in which a serving cell and the non-serving cell have same uplink and downlink bandwidth part (BWP) configurations and receiving the serving cell configuration in which the serving cell and the non-serving cell have different SSB configurations,
- wherein inter-cell multi-transmission/Reception Point (TRP) operation is configured for the terminal.
A base station comprising:
- a transmitter that transmits a synchronization signal block (SSB) of a non-serving cell;
- and
- a processor that controls a transmission configuration indication (TCI) state of a reference signal, the TCI state indicating a specific quasi co-location (QCL) type with the SSB of the non-serving cell,
- wherein the transmitter transmits a serving cell configuration in which a serving cell and the non-serving cell have same uplink and downlink bandwidth part (BWP) configurations and transmits the serving cell configuration in which the serving cell and the non-serving cell have different SSB configurations, and
- inter-cell multi-transmission/Reception Point (TRP) operation is configured for a terminal.
A system comprising a terminal and a base station, wherein

- the terminal comprises:
- a receiver that receives the SSB of the non-serving cell;
- and
- a processor that determines that a transmission configuration indication (TCI) state of a reference signal indicates a specific quasi co-location (QCL) type with the SSB of the non-serving cell,
- wherein the receiver receives a serving cell configuration in which a serving cell and the non-serving cell have same uplink and downlink bandwidth part (BWP) configurations and receives the serving cell configuration in which the serving cell and the non-serving cell have different SSB configurations, and
- inter-cell multi-transmission/Reception Point (TRP) operation is configured for the terminal.
