Title:
USER DEVICE AND METHOD PERFORMED BY BASE STATION
Document Type and Number:
Japanese Patent JP2020039147
Kind Code:
A
Abstract:
To provide a method and a device that perform uplink (UL) scheduling and a method and a device that perform UL transmission.SOLUTION: A method that performs UL scheduling includes determining at least two modes for UL scheduling on the basis of the number of downlink (DL) subframes and the number of UL subframes. In each of the at least two modes, a different scheduling time delay is displayed.SELECTED DRAWING: Figure 1
