Abstract
The present invention is designed so that UCI can be transmitted properly even when a PUSCH of a long TTI and an sPUSCH of a short TTI collide with each other in a same carrier. According to the present invention, a user terminal has a transmission section that transmits UCI, and a control section that controls re-direction of at least part of the UCI, when a PUSCH of a long TTI carrying the UCI, and an sPUSCH of a short TTI, collide with each other in a same carrier.
Claims3
A terminal comprising:
- a transmitter configured to transmit a first physical uplink shared channel (PUSCH) using a first period and a second PUSCH using a second period that is shorter than the first period;
- and
- a processor configured to, when the first PUSCH and the second PUSCH overlap in time, control a dropping of at least a part of the first PUSCH, based on a timing of the overlapping,
- wherein the processor is configured to control to drop the part of the first PUSCH that is subjected to transmission after a certain timing, the certain timing being before start of the timing of the overlapping.
A radio communication method for a terminal comprising:
- transmitting a first physical uplink shared channel (PUSCH) using a first period and a second PUSCH using a second period that is shorter than the first period;
- and
- when the first PUSCH and the second PUSCH overlap in time, controlling a dropping of at least a part of the first PUSCH, based on a timing of the overlapping,
- wherein the terminal performs a control to drop the part of the first PUSCH that is subjected to transmission after a certain timing, the certain timing being before start of the timing of the overlapping.
A system comprising a terminal and a base station, wherein the terminal comprises:
- a transmitter configured to transmit a first physical uplink shared channel (PUSCH) using a first period and a second PUSCH using a second period that is shorter than the first period;
- and
- a processor configured to, when the first PUSCH and the second PUSCH overlap in time, control a dropping of at least a part of the first PUSCH, based on a timing of the overlapping,
- wherein the processor is configured to control to drop the part of the first PUSCH that is subjected to transmission after a certain timing, the certain timing being before start of the timing of the overlapping, and
- the base station comprises a receiver configured to receive the first PUSCH and the second PUSCH.
