The present invention provides a communication method,
communication device, and storage medium that reduce overhead and improve
throughput. [Solution] The method includes the steps of generating a
physical layer protocol data unit (PPDU) and transmitting the PPDU. The first
signal field of the PPDU includes a resource unit allocation subfield and a user field for each user, the resource unit allocation subfield indicating the
frequency domain resources of the user in each user field, the user in each user field includes a first user using coupled source channel coding, the PPDU further includes a second
signal field for the first user using coupled source channel coding, the second
signal field for the first user indicates the coupled source channel coding parameters of the first user's source layer, and the second
signal field for the first user is located on the first user's
frequency domain resources.
