Abstract

To appropriately perform CSI measurement and reporting for multi-panel/TRP. A terminal according to one aspect of the present disclosure includes a receiving section that receives configuration information related to a plurality of pairs of channel measurement resources, and a control section that controls, on the basis of the configuration information, group-based beam reporting or channel state information reporting for a plurality of transmission/reception points.

Claims (16)

1 . A terminal comprising:

a processor that determines that a same channel measurement resource (CMR) can be included in multiple CMR pairs in a first frequency band, and determines that a same CMR is not included in the multiple CMR pairs in a second frequency band that is higher than the first frequency band; and

a transmitter that transmits a channel state information (CSI) report regarding the multiple CMR pairs.

2 . The terminal according to claim 1 , wherein a repetition periodicity of two CMRs included in a certain pair differs among the multiple CMR pairs.

3 . A radio communication method for a terminal, comprising:

determining that a same channel measurement resource (CMR) can be included in multiple CMR pairs in a first frequency band, and determining that a same CMR is not included in the multiple CMR pairs in a second frequency band that is higher than the first frequency band; and

transmitting a channel state information (CSI) report regarding the multiple CMR pairs.

4 . A base station comprising:

a processor that configures, in a terminal, multiple channel measurement resource (CMR) pairs including a same CMR in a first frequency band, and configures, in the terminal, multiple CMR pairs not including a same CMR in a second frequency band that is higher than the first frequency band; and

a receiver that receives a channel state information (CSI) report regarding the multiple CMR pairs configured in the terminal.

5 . A system comprising a terminal and a base station, wherein

the terminal comprises:

a processor that determines that a same channel measurement resource (CMR) can be included in multiple CMR pairs in a first frequency band, and determines that a same CMR is not included in the multiple CMR pairs in a second frequency band that is higher than the first frequency band; and

a transmitter that transmits a channel state information (CSI) report regarding the multiple CMR pairs, and

the base station comprises:

a receiver that receives the CSI report.
