Title:
TERMINAL DEVICE
Document Type and Number:
WIPO Patent Application WO/2019/194269
Kind Code:
A1
Abstract:
Provided are a base station device, a terminal device, and a communication method, with which it is possible to ensure low delay and high reliability in URLLC. The present invention comprises a transmission unit that can perform data transmission with a reception unit that detects first and second DCI formats and RRC information, the data transmission being performed through any of a first uplink grant that can be used at the activation of the first DCI format with the cycle of a wireless resource included in the RRC information, a second uplink grant that can be used at the activation of the second DCI format with the cycle of the wireless resource included in the RRC information, or a third uplink grant that can be used after detection of the second DCI format. A plurality of DCI formats are detected. The transmission unit performs an override when the third uplink grant overlaps with the second uplink grant in a time region, and performs an override when the first uplink grant overlaps with the third uplink grant in a time region.
