US 2021/0282162 A1 · USER TERMINAL AND RADIO COMMUNICATION METHOD

Abstract

The present invention is designed to support appropriate CSI measurements and reporting even when shortened TTIs and/or processing time reduction are introduced. A user terminal according to one aspect of the present invention communicates in a cell, which uses a shortened transmission time interval (TTI) that has a shorter TTI duration than 1 ms and/or in a cell in which communication is controlled by applying shortened processing time that is shorter than processing time in an existing LTE system, and this user terminal has a measurement section that measures channel state information (CSI) by using a CSI reference resource, and a transmission section that transmits the CSI in a given subframe, and the CSI reference resource is found in a subframe that is located a period before the given subframe, the period being shorter than a given time period.
