A base station apparatus controls an access scheme for each radio resource by using higher layer signaling such that only signals generated by a same type of a signal generation method are multiplexed for each radio resource.
Claims5
A communication apparatus for communicating with multiple terminal apparatuses by using multiple access schemes, the communication apparatus at least comprising:
- a controller configured to generate a control signal;
- and
- a receiver configured to receive a signal from the terminal apparatus, wherein
- the controller generates a signal to identify a communication slot that allows grant-free communication with the terminal apparatus, and
- methods of subcarrier allocation to be used in the communication slot identified at least include a method that uses only a continuous subcarrier allocation and a method that includes a non-continuous subcarrier allocation.
