Abstract
A terminal is disclosed that includes a transmitter that transmits a physical uplink shared channel (PUSCH) and a measurement reference signal (sounding reference signal (SRS)) and a processor that performs sensing and controls to contiguously transmit the PUSCH and the SRS after the sensing. In other aspects, a radio communication method and a base station are disclosed.
Claims5
A terminal comprising:
- a receiver that receives a downlink (DL) signal;
- a transmitter that transmits a physical uplink shared channel (PUSCH) and a sounding reference signal (SRS);
- and
- a processor that controls the transmitter to transmit each of the PUSCH and the SRS in accordance with a downlink control information (DCI) included in the DL signal, the SRS being triggered by the DCI,
- wherein the processor allocates the PUSCH to symbols in an uplink (UL) subframe except the last one or more symbols in the UL subframe, and transmits the PUSCH following transmission of the SRS, based on the DCI included in the DL signal, and
- wherein the processor performs listening prior to the transmission of the SRS.

A radio base station comprising:
- a transmitter that transmits, to a terminal, a downlink (DL) signal including downlink control information (DCI) to trigger each of transmission of a physical uplink shared channel (PUSCH) and transmission of a sounding reference signal (SRS);
- and
- a receiver that receives the PUSCH and the SRS that are transmitted from the terminal in accordance with the DCI such that the PUSCH is received after the SRS,
- wherein the transmitter transmits, to the terminal, the DL signal including the DCI to allocate the PUSCH to symbols in an uplink (UL) subframe except the last one or more symbols in the UL subframe.
1 more element
A radio communication method performed by a terminal, comprising:
- receiving a downlink (DL) signal;
- transmitting a physical uplink shared channel (PUSCH) and a sounding reference signal, SRS;
- and
- controlling to transmit each of the PUSCH and the SRS in accordance with a downlink control information (DCI) included in the DL signal, the SRS being triggered by the DCI,
- wherein the terminal allocates the PUSCH to symbols in an uplink (UL) subframe except the last one or more symbols in the UL subframe, and transmits the PUSCH following transmission of the SRS, based on the DCI included in the DL signal, and
- wherein the terminal performs listening prior to the transmission of the SRS.
