First Claim
1. A control apparatus that performs communication with a plurality of communication apparatuses including a first communication apparatus, a second communication apparatus, and a third communication apparatus, the control apparatus comprising:
- an allocation unit configured to allocate;
a first communication slot for the first, second, and third communication apparatuses to receive first data directly transmitted from a data source,a second communication slot for the second and third communication apparatuses to receive second data transmitted from the first communication apparatus, the second data being obtained by performing a relay transmission of the first data in the first communication apparatus, anda third communication slot for the third communication apparatus to receive third data transmitted from the second communication apparatus, the data being obtained by performing maximum likelihood processing based on the first data transmitted from the data source in the first communication slot, the second data transmitted from the first communication apparatus in the second communication slot, and the third data transmitted from the second communication apparatus in the third communication slot; and
a notification unit configured to notify at least the first, the second, and the third communication apparatuses of the communication slots allocated by the allocation unit.
