USER EQUIPMENT, METHOD, AND BASE STATION
Document Type and Number:
Japanese Patent JP2021002868
Kind Code:
A
Abstract:
To enable a BS and UE to appropriately transmit and receive aperiodic signals.SOLUTION: User equipment according to one or more embodiments of the present invention comprises: a receiver that receives a timing offset between a time when a trigger request to trigger aperiodic channel state information (CSI) reporting is transmitted and a time when a non-zero power channel state information reference signal is transmitted, receives the trigger request, and receives an IMR, i.e., aperiodic interference measurement resource (IMR); and a processor that performs interference measurements on the basis of the IMR, and controls the transmission of an aperiodic channel state information (CSI) report on the basis of the interference measurements. The processor applies the timing offset to the aperiodic IMR.SELECTED DRAWING: Figure 6
