User terminal and radio communication method
To appropriately control UL transmission such as a CSI reporting when performing communication by applying a different configuration from those of legacy LTE systems, a user terminal according to one aspect of the present disclosure includes: a transmission section that transmits one or more UL signals by using an uplink shared channel based on an instruction from a base station; and a control section that controls the transmission assuming that transmission durations of a plurality of UL signals do not overlap in a same symbol, or, when at least part of the transmission durations of the plurality of UL signals overlap in the same symbol, performs control to select and transmit the part of the UL signals.
1. A terminal comprising:
a receiver that receives a Downlink Control Information (DCI) to trigger an Aperiodic Channel State Information (A-CSI) report; and
a processor that controls to not transmit a plurality of A-CSI reports in a given transmission duration,
wherein, when the plurality of A-CSI reports is triggered by different DCIs, the processor does not expect to transmit, in a single carrier, the plurality of A-CSI reports on overlapping Orthogonal Frequency Division Multiplexing (OFDM) symbols, the plurality of A-CSI reports using a physical uplink shared channel.
2. The terminal according to claim 1 , wherein the given transmission duration is a slot.
3. The terminal according to claim 1 , wherein, when the plurality of A-CSI reports to be transmitted on different carriers is triggered by the different DCIs, the processor expects to transmit the plurality of A-CSI reports on the overlapping OFDM symbols.
4. The terminal according to claim 1 , wherein the processor controls not to transmit the plurality of A-CSI reports triggered by the different DCI in the same transmission duration in a cell group.
5. A radio communication method for a terminal, comprising:
receiving a Downlink Control Information (DCI) to trigger an Aperiodic Channel State Information (A-CSI) report; and
controlling to not transmit a plurality of A-CSI reports in a given transmission duration,
wherein, when the plurality of A-CSI reports is triggered by different DCIs, the terminal does not expect to transmit, in a single carrier, the plurality of A-CSI reports on overlapping Orthogonal Frequency Division Multiplexing (OFDM) symbols, the plurality of A-CSI reports using a physical uplink shared channel.
6. A base station comprising:
a transmitter that transmits a Downlink Control Information (DCI) to trigger an Aperiodic Channel State Information (A-CSI) report; and
a processor that controls triggering of transmission of a plurality of A-CSI reports in a given transmission duration,
wherein, when the plurality of A-CSI reports is triggered by different DCIs, the processor does not expect to receive, in a single carrier, the plurality of A-CSI reports on overlapping Orthogonal Frequency Division Multiplexing (OFDM) symbols, the plurality of A-CSI reports using a physical uplink shared channel.
7. A system comprising a terminal and a base station, wherein:
the terminal comprises:
a receiver that receives a Downlink Control Information (DCI) to trigger an Aperiodic Channel State Information (A-CSI) report; and
a first processor that controls to not transmit a plurality of A-CSI reports in a given transmission duration,
wherein, when the plurality of A-CSI reports is triggered by different DCIs, the first processor does not expect to transmit, in a single carrier, the plurality of A-CSI reports on overlapping Orthogonal Frequency Division Multiplexing (OFDM) symbols, the plurality of A-CSI reports using a physical uplink shared channel; and
the base station comprises:
a transmitter that transmits the DCI; and
a second processor that controls triggering of transmission of the plurality of A-CSI reports in the given transmission duration.
