Claims

1. A user terminal comprising:
a processor and a memory, wherein the processor:
measures reception power,
determines information about a percentage of channel occupancy time in a given time interval based on a measurement result of the reception power, and
controls to transmit a feedback report including the information about the percentage of channel occupancy time,
wherein the processor determines the given time interval based on information about the given time interval provided by higher layer signaling, and
wherein the processor determines the percentage of channel occupancy time based on a number of measurement results that are beyond a given threshold among a plurality of measurement results of the reception power in the given time interval.
2. A radio communication method for a user terminal, comprising:
measuring reception power;
determining information about a percentage of channel occupancy time in a given time interval based on a measurement result of the reception power; and
controlling to transmit a feedback report including the information about the percentage of channel occupancy time,
wherein the given time interval is determined based on information about the given time interval provided by higher layer signaling, and
wherein the percentage of channel occupancy time is determined based on a number of measurement results that are beyond a given threshold among a plurality of measurement results of the reception power in the given time interval.
3. A radio communication system comprising:
a user terminal that determines information about a percentage of channel occupancy time in a given time interval based on a measurement result of reception power; and
a radio base station that:
transmits information about the given time interval to the user terminal by higher layer signaling, and
receives the information about the percentage of channel occupancy time from the user terminal,
wherein the user terminal determines the given time interval based on information about the given time interval provided by higher layer signaling, and
wherein the user terminal determines the percentage of channel occupancy time based on a number of measurement results that are beyond a given threshold among a plurality of measurement results of the reception power in the given time interval.
