Abstract:

[Object] To provide a mechanism that can improve the transmission efficiency of the entire system in an environment in which dynamic resource sharing is performed. [Solving Means] Provided is a communication apparatus that communicates with a base station apparatus that receives first uplink data of grant-free transmission and second uplink data of grant-based transmission, the communication apparatus including: a setting unit that performs setting regarding grant-free transmission available resources based on setting information received from the base station apparatus; and a communication processing unit that receives, in a predetermined first slot, a downlink control channel including parameter information for grant-free transmission and that uses uplink resources selected from the grant-free transmission available resources to transmit the first uplink data generated based on the parameter information.
