Abstract

A terminal including: a reception unit configured to receive, from a base station apparatus, configuration information of a plurality of search spaces each of which is associated with a control resource set, wherein, between a plurality of control resource sets associated with the plurality of search spaces, values of parameters of a part of a plurality of parameters that each control resource set has are common, and the reception unit monitors a downlink physical control channel using a frequency domain resource designated by all of or a part of the plurality of control resource sets.

Claims (26)

1 . A terminal comprising:

a reception unit configured to receive configuration information of a search space designating a plurality of frequency domain resources for monitoring a PDCCH;

a control unit configured to monitor a PDCCH within a time duration in the plurality of frequency domain resources, wherein the time duration is the same among the plurality of frequency domain resources; and

a transmission unit configured to transmit a maximum supported number of the plurality of frequency domain resources to a base station apparatus as capability information,

wherein the time duration is designated by configuration information of a control resource set associated with the search space, and

wherein the terminal receives information indicating a start of a Channel Occupancy Time (COT).

2 . A base station comprising:

a transmission unit configured to transmit, to a terminal, configuration information of a search space designating a plurality of frequency domain resources for monitoring a PDCCH;

a control unit configured to control the transmission unit such that the transmission unit transmits a signal by a PDCCH within a time duration in the plurality of frequency domain resources, wherein the time duration is the same among the plurality of frequency domain resources; and

a reception unit configured to receive a maximum supported number of the plurality of frequency domain resources from the terminal as capability information,

wherein the time duration is designated by configuration information of a control resource set associated with the search space, and

wherein the base station transmits, to the terminal, information indicating a start of a Channel Occupancy Time (COT).

3 . A system comprising:

a terminal comprising:

a reception unit configured to receive configuration information of a search space designating a plurality of frequency domain resources for monitoring a PDCCH;

a control unit configured to monitor a PDCCH within a time duration in the plurality of frequency domain resources, wherein the time duration is the same among the plurality of frequency domain resources; and

a transmission unit configured to transmit a maximum supported number of the plurality of frequency domain resources to a base station apparatus as capability information,

wherein the time duration is designated by configuration information of a control resource set associated with the search space, and

wherein the terminal receives information indicating a start of a Channel Occupancy Time (COT), and

a base station comprising a transmission unit configured to transmit the configuration information and a reception unit configured to receive the maximum number of the plurality of frequency domain resources from the terminal as the capability information.

4 . A communication method executed by a terminal, the communication method comprising:

receiving configuration information of a search space designating a plurality of frequency domain resources for monitoring a PDCCH;

monitoring a PDCCH within a time duration in the plurality of frequency domain resources, wherein the time duration is the same among the plurality of frequency domain resources; and

transmitting a maximum supported number of the plurality of frequency domain resources to a base station apparatus as capability information,

wherein the time duration is designated by configuration information of a control resource set associated with the search space, and

wherein the terminal receives information indicating a start of a Channel Occupancy Time (COT).
