Terminal, radio communication method, and base station
According to an aspect of the present disclosure, there is provided a terminal including: a receiving section configured to receive information giving an instruction on activation or deactivation of a panel; and a control section configured to perform control to perform a communication operation using the panel or a communication operation not using the panel after a certain offset period with reference to at least one of a reception timing of the information and a transmission timing of a delivery confirmation signal for the information.
1. A terminal comprising:
a receiver configured to receive a Medium Access Control Control Element (MAC CE) giving an instruction on activation of a transmission configuration indicator (TCI) state; and
a processor configured to perform control to perform a communication operation using the TCI state after an offset period starting from at least one of a reception timing of the MAC CE and a transmission timing of a delivery confirmation signal for the MAC CE,
wherein the processor determines the offset period based on whether or not a TCI state for use in a communication operation after the offset period is activated.
2. The terminal according to claim 1 , wherein the offset period is determined in at least one unit of a subframe, a slot, a subslot, and a symbol on the basis of a subcarrier spacing of an uplink control channel used to transmit the delivery confirmation signal.
3. A radio communication method of a terminal, comprising:
receiving a Medium Access Control Control Element (MAC CE) giving an instruction on activation of a transmission configuration indicator (TCI) state; and
performing control to perform a communication operation using the TCI state after an offset period starting from at least one of a reception timing of the MAC CE and a transmission timing of a delivery confirmation signal for the MAC CE,
wherein the offset period is determined based on whether or not a TCI state for use in a communication operation after the offset period is activated.
4. A base station comprising:
a transmitter configured to transmit a Medium Access Control Control Element (MAC CE) giving an instruction on activation of a transmission configuration indicator (TCI) state; and
a processor configured to determine that a communication operation using the TCI state is performed in the terminal after an offset period starting from at least one of a reception timing of the MAC CE and a transmission timing of a delivery confirmation signal for the MAC CE,
wherein the processor determines the offset period based on whether or not a TCI state for use in a communication operation after the offset period is activated.
5. A system comprising a terminal and a base station, wherein:
the terminal comprises:
a receiver configured to receive a Medium Access Control Control Element (MAC CE) giving an instruction on activation of a transmission configuration indicator (TCI) state; and
a processor configured to perform control to perform a communication operation using the TCI state after an offset period starting from at least one of a reception timing of the MAC CE and a transmission timing of a delivery confirmation signal for the MAC CE,
wherein the processor determines the offset period based on whether or not a TCI state for use in a communication operation after the offset period is activated, and
the base station comprises:
a transmitter configured to transmit the MAC CE; and
a processor configured to determine that a communication operation using the TCI state is performed in the terminal after an offset period starting from at least one of a reception timing of the MAC CE and a transmission timing of a delivery confirmation signal for the MAC CE.
6. The terminal according to claim 1 , wherein when the TCI state is not activated, the processor determines the offset period by adding a given value.
7. The terminal according to claim 6 , wherein the given value is based on a value corresponding to a capability of the terminal.
