Abstract
Provided are a base station apparatus, a terminal apparatus, and a communication method, in a case that uplink data transmission based on orthogonal multiple access and uplink data transmission based on non-orthogonal multiple access coexist in a cell in which many terminal apparatuses present, capable of maintaining a prescribed communication quality for the uplink data. The base station apparatus for communicating with a terminal apparatus configured to support contention based access and non-contention based access transmits, in a case that an uplink data channel received in a non-contention based manner occurs in a subframe including the contention based access region, a contention based transmission configuration change notification with respect to a subframe configured to receive the uplink data channel.
