Terminal, radio communication method, and base station
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.
1 . 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.
2 . The terminal according to claim 1 , wherein the reference signal is a channel state information reference signal (CSI-RS).
3 . The terminal according to claim 1 , wherein the reference signal is a CSI-RS in a non-zero power (NZP)-CSI-RS resource set with tracking reference signal (TRS) information.
4 . 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.
5 . 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.
6 . A system comprising a terminal and a base station, wherein
the base station comprises:
a transmitter that transmits a synchronization signal block (SSB) of a non-serving cell, and
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.
