Terminal and radio communication method
A terminal according to one aspect of the present disclosure includes: a control section that determines a power control parameter for a physical uplink shared channel (PUSCH), based on reception of a medium access control control element (MAC CE); and a transmitting section that transmits the PUSCH by using transmission power based on the power control parameter. According to one aspect of the present disclosure, a parameter for transmission power control can be appropriately determined.
1. A terminal comprising:
a receiving section that receives a medium access control-control element (MAC CE) indicating a transmission configuration indication (TCI) state for a physical downlink control channel; and
a control section that, when a reference signal for pathloss reference for a physical uplink shared channel is not configured, applies to transmission of the physical uplink shared channel a pathloss estimation based on the TCI state.
2. The terminal according to claim 1 , wherein the pathloss estimation is based on a reference signal with quasi co-location type of type D in the TCI state.
3. The terminal according to claim 1 , wherein the physical downlink control channel is in a control resource set with the lowest control resource set ID.
4. A radio communication method for a terminal, comprising:
receiving a medium access control-control element (MAC CE) indicating a transmission configuration indication (TCI) state for a physical downlink control channel; and
applying, when a reference signal for pathloss reference for a physical uplink shared channel is not configured, to transmission of the physical uplink shared channel a pathloss estimation based on the TCI state.
5. A base station comprising:
a transmitting section that transmits a medium access control-control element (MAC CE) indicating a transmission configuration indication (TCI) state for a physical downlink control channel; and
a control section that controls reception of a physical uplink shared channel,
wherein when a reference signal for pathloss reference for the physical uplink shared channel is not configured, a pathloss estimation based on the TCI state is applied to transmission of the physical uplink shared channel.
6. A system comprising a terminal and a base station, wherein
the terminal comprises:
a receiving section that receives a medium access control-control element (MAC CE) indicating a transmission configuration indication (TCI) state for a physical downlink control channel; and
a control section that, when a reference signal for pathloss reference for a physical uplink shared channel is not configured, applies to transmission of the physical uplink shared channel a pathloss estimation based on the TCI state, and
the base station transmits the MAC CE.
7. The terminal according to claim 6 , wherein the physical downlink control channel is in a control resource set with the lowest control resource set ID.
