## Abstract

A terminal including: a transmission unit configured to, when a first RAT (Radio Access Technology) and a second RAT are operated using a same band, transmit information to a network, the information indicating whether or not a downlink control channel candidate of the second RAT including a symbol in which a reference signal of the first RAT is located can be received; a reception unit configured to receive a CORESET (Control Resource Set) configuration from a network; and a control unit configured to monitor the downlink control channel candidate including the symbol, based on the CORESET configuration. The control unit does not expect that a specific CORESET and a rate matching pattern of a reference signal of the first RAT are to be configured.

## Claims

### Claim at position 1

-6. (Canceled)

### Claim 7

A terminal comprising:
a transmission unit configured to transmit, to a network, capability information related to whether or not a downlink control channel candidate of a second RAT (Radio Access Technology) including a resource element in which a reference signal of a first RAT is located can be received; and
a control unit configured to monitor the downlink control channel candidate including the resource element in which the reference signal is located, when transmitting the capability information, wherein
the capability information indicates that the downlink control channel candidate can be received even in a case where a plurality of patterns of the reference signal that do not overlap with each other in a frequency domain are configured in the terminal.

### Claim 8 (depends on 7)

The terminal as claimed in claim 7, wherein
the control unit performs control of not monitoring the downlink control channel candidate in a case where a plurality of patterns of the reference signal that overlap with each other in the frequency domain are configured in the terminal.

### Claim 9 (depends on 7)

The terminal as claimed in claim 7, further comprising:
a reception unit configured to receive, from the network, first information configuring a control resource set of the downlink control channel candidate and second information related to a pattern of the reference signal, wherein
the control unit monitors the downlink control channel candidate when transmitting the capability information in a case where the downlink control channel candidate based on the first information overlaps with the resource element based on the second information.

### Claim 10

A communication method performed by a terminal, the communication method comprising:
transmitting, to a network, capability information related to whether or not a downlink control channel candidate of a second RAT (Radio Access Technology) including a resource element in which a reference signal of a first RAT is located can be received; and
monitoring the downlink control channel candidate including the resource element in which the reference signal is located, when transmitting the capability information, wherein
the capability information indicates that the downlink control channel candidate can be received even in a case where a plurality of patterns of the reference signal that do not overlap with each other in a frequency domain are configured in the terminal.
