Title:
USER TERMINAL AND WIRELESS COMMUNICATIONS METHOD
Document Type and Number:
WIPO Patent Application WO/2018/012456
Kind Code:
A1
Abstract:
In order for a user terminal to appropriately send UCI when communicating using a plurality of carriers having the same and/or different TTI lengths, this user terminal comprises: a reception unit that receives a downlink (DL) shared channel; a transmission unit that sends uplink control information (UCI) containing resend control information for the DL shared channel; and a control unit that controls transmission of the UCI, on the basis of the UL shared channel allocations in at least one uplink (UL) carrier having the same and/or different time lengths for transmission time intervals (TTI) as the DL carrier receiving the DL shared channel.
