Title:
USER TERMINAL AND RADIO COMMUNICATIONS METHOD
Document Type and Number:
WIPO Patent Application WO/2018/084212
Kind Code:
A1
Abstract:
In order to appropriately use shortened TTI and/or shortened processing time and control communications when communicating using a plurality of cells (CC) during DL and/or UL transmission, this user terminal uses a plurality of cells and communicates during DL transmission and/or UL transmission and has: a reception unit that receives DL signals; and a control unit that controls the transmission of UL signals at a prescribed timing, on the basis of the DL signals. The control unit controls the prescribed timing on the basis of at least the number of cells used in UL transmission.
