Title:
USER TERMINAL, BASE STATION, AND RADIO COMMUNICATION METHOD
Document Type and Number:
WIPO Patent Application WO/2019/030869
Kind Code:
A1
Abstract:
In order to perform communication properly even when the transmission timing/transmission period of retransmission control information is flexibly controlled (becomes variable), one aspect of a user terminal according to the present invention has: a transmission unit that transmits retransmission control information for DL transmission; and a control unit that controls transmission of the retransmission control information at a prescribed timing, notification of said timing having been provided from a base station, wherein a time window is set for the retransmission control information, the control unit controls the transmission of the retransmission control information on the basis of the prescribed timing and the time window that was set for the retransmission control information, and at least one instance of the prescribed timing is included in the range of the time window.
