Classification: CPC H  Y | IPC H

Claim 2:
3. A wireless communication method comprising:
a transmission device receiving an input of group-addressed data transmitted from a specific source, converting the group-addressed data into wireless frames, and performing group-addressed transmission of the wireless frames; and
a reception device receiving the wireless frames transmitted from the transmission device, and identifying and acquiring the group-addressed data of the specific source,
wherein
the transmission device executes a coding step of defining a plurality of wireless frames as a frame block, performing error correction coding on the frame block, and performing group-addressed transmission of the frame block, wherein a first identifier indicating the group-addressed data transmitted from the specific source and a second identifier indicating that error correction coding has been performed in units of frame block are added to the wireless frames, and
the reception device executes a decoding step of identifying the frame block from the received wireless frames, performing error correction decoding in units of frame block, and reconfiguring the group-addressed data of the specific source, wherein the reception device uses the first and second identifiers to decode the frame block and identify the group-addressed data of the specific source.
