User terminal and radio communication method
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.
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.
