The transmission device according to claim 1, wherein
the plurality of divisions includes a first division and a second division,
the first division includes at least one of header information or control information, and
the second division includes payload information subjected to signal processing for transmission in a radio section between a radio device and a terminal device connected through the fronthaul.

### Claim 3 (depends on 2)

The transmission device according to claim 2, wherein the header information included in the first division is header information for a transmission section of the fronthaul.

### Claim 4 (depends on 2)

The transmission device according to claim 2, wherein the header information included in the first division includes header information for the radio section and header information for a transmission section of the fronthaul.

### Claim 5 (depends on 1)

The transmission device according to claim 1, wherein
the plurality of divisions includes a first division and a second division, and
the controller is configured to apply a transmission scheme having higher error tolerance to the first division than to the second division.

### Claim 6 (depends on 1)
