Wireless communication system, and wireless communication method

A wireless communication system comprising:

• a transmission device configured to receive an input of group-addressed data transmitted from a specific source, convert the group-addressed data into wireless frames, and perform group-addressed transmission of the wireless frames;
• and
• a reception device configured to receive the wireless frames transmitted from the transmission device, and identify and acquire the group-addressed data of the specific source,
• wherein
• the transmission device includes a coding unit, including one or more processors, configured to define 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 includes a decoding unit, including one or more processors, configured to identify 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.
