Abstract

Official abstract text for this publication.

A user terminal has a control section that makes a determination of at least one of a band of monitoring for at least one of a reference signal and a downlink control channel, and operation of the monitoring, in a frequency band to which sensing of a channel is applied, based on at least one of notified configuration information and reported capability information, and a receiving section that performs the monitoring according to the determination. According to one aspect of the present disclosure, it is possible to perform proper communication in an unlicensed band.

First claim

Opening claim text (preview).

The invention claimed is: 1. A terminal comprising: a processor that determines a band in frequency domain of monitoring for a reference signal and a downlink control channel, and determines operation of the monitoring, in a frequency band to which sensing of a channel is applied, based on received configuration information and transmitted capability information; and a receiver that performs the monitoring according to the determined band and the determined operation, wherein when the determined band is equal to a control resource set (CORESET) band configured by the received configuration information for the downlink control channel, the receiver performs the monitoring in the control resource set band, and when the determined band is not equal to the configured CORESET band, the receiver performs the monitoring in each of a plurality of subbands within the determined band. 2. A radio communication method of a terminal, including: determining a band in frequency domain of monitoring for a reference signal and a downlink control channel, and determining operation of the monitoring, in a frequency band to which sensing of a channel is applied, based on received configuration information and transmitted capability information; and performing the monitoring according to the determined band and the determined operation, wherein when the determined band is equal to a control resource set (CORESET) band configured by the received configuration information for the downlink control channel, the terminal performs the monitoring in the control resource set band, and when the determined band is not equal to the configured CORESET band, the terminal performs the monitoring in each of a plurality of subbands within the determined band. 3. A base station comprising: a processor that determines a band in frequency domain of transmission for a reference signal and a downlink control channel, and operation of the transmission, in a frequency band to which sensing of a channel is applied, based on transmitted configuration information and received capability information; and a transmitter that performs the transmission according to the determined band, wherein when the determined band is equal to a control resource set (CORESET) band configured by the transmitted configuration information for the downlink control channel, the transmitter performs the transmission in the control resource set band, and when the determined band is not equal to the configured CORESET band, the transmitter performs the transmission in each of a plurality of subbands within the determined band. 4. A system comprising: a processor that determines a band in frequency domain of monitoring for a reference signal and a downlink control channel, and determines operation of the monitoring, in a frequency band to which sensing of a channel is applied, based on received configuration information and transmitted capability information; and a receiver that performs the monitoring according to the determined band and the determined operation; and a base station that performs transmission for the reference signal and the downlink control channel, wherein when the determined band is equal to a control resource set (CORESET) band configured by the received configuration information for the downlink control channel, the receiver performs the monitoring in the control resource set band, and when the determined band is not equal to the configured CORESET band, the receiver performs the monitoring in each of a plurality of subbands within the determined band.
