Title:
BASE STATION DEVICE, TERMINAL DEVICE, AND COMMUNICATION METHOD THEREFOR
Document Type and Number:
WIPO Patent Application WO/2017/195815
Kind Code:
A1
Abstract:
Provided are a base station device, a terminal device, and a communication method with which, when uplink data transmissions based on orthogonal multiple access and uplink data transmissions based on non-orthogonal multiple access are mixed in a cell in which a plurality of terminal devices are present, a prescribed communication quality can be maintained for the uplink data of the transmissions. If an uplink data channel received in a non-contention-based manner by the base station device, which communicates with terminal devices that support contention-based access and non-contention-based access, occurs in a sub-frame including a contention-based access region, the base station device transmits a contention-based transmission configuration modification notification for the sub-frame receiving the uplink data channel.
