Title:
USER TERMINAL, WIRELESS BASE STATION, AND WIRELESS COMMUNICATION METHOD
Document Type and Number:
WIPO Patent Application WO/2017/164141
Kind Code:
A1
Abstract:
The present invention favorably achieves a delay reduction effect even when using TDD. A user terminal for communicating by using a wireless frame that includes a flexible subframe, the subframe type of which can be changed, the user terminal being one which has: a control unit which controls transmission and receipt by using a first subframe type that contains, in one subframe, a UL control channel, a DL control channel, and a UL data channel and/or a DL data channel, and also by using a second subframe type for performing UL transmission or DL transmission in one subframe; and a receiving unit for receiving information pertaining to the subframe type set for each flexible subframe.
