TERMINAL, WIRELESS COMMUNICATION METHOD, AND BASE STATION

Title:

TERMINAL, WIRELESS COMMUNICATION METHOD, AND BASE STATION

Document Type and Number:

WIPO Patent Application WO/2021/229760

Kind Code:

A1

Abstract:

A terminal according to one aspect of the present disclosure has: a reception unit that, when there is no downlink signal with an indicated TCI state in the same symbol as an aperiodic channel state information reference signal (A-CSI-RS), receives the A-CSI-RS using two default transmission configuration indication (TCI) states for a physical downlink shared channel; and a control unit that uses, for measurement of the A-CSI-RS, one default TCI state of the two default TCI states on the basis of at least one of capability information and a physical downlink control channel for triggering of the A-CSI-RS. This aspect of the present disclosure makes it possible to appropriately measure the A-CSI-RS.
