Title:
USER TERMINAL AND WIRELESS COMMUNICATION METHOD
Document Type and Number:
WIPO Patent Application WO/2018/088415
Kind Code:
A1
Abstract:
The purpose of the present invention is to suitably execute a random access procedure in future wireless communication systems. This user terminal, which uses a random access procedure, is provided with: a reception unit which receives a collision resolving message in the random access; and a control unit for controlling transmission of a delivery acknowledgement signal for the collision resolving message. The control unit implements control on the basis of uplink control channel setting information included in at least the collision resolving message or a response signal for the random access, such that a prescribed uplink control channel resource is used to transmit the delivery acknowledgement signal.
