Title:
USER DEVICE AND BASE STATION DEVICE
Document Type and Number:
WIPO Patent Application WO/2019/098236
Kind Code:
A1
Abstract:
Provided is a user device having: a generation unit for communicating with a base station device and generating terminal capability information that includes information indicating an uplink band combination, information indicating whether or not simultaneous transmission in the uplink band combination is possible, and information indicating the maximum sensitivity degradation when simultaneous transmission is performed in the uplink band combination; a transmission unit for transmitting the generated terminal capability information to the base station device; and a reception unit for receiving an uplink scheduling allocation from the base station device. The user device performs simultaneous transmission in the uplink band combination on the basis of the uplink scheduling allocation.
