PURPOSE:To allow a relay request station to surely receive a relay result report by designating a transmission destination with a destination registration table whose reception station and relay station are specified by a registration number and informing the return destination of a relay result report based on the registration number of the destination registration table. CONSTITUTION:Each of relay stations FT1-FT3 has a registration table in which information of representing direct transmission from its own station to reception stations FT3-FT6 and relay stations FT1-FT3 of next stage corresponding to the reception stations FT3-FT6 is registered while a registration number is provided, and when transmission request stations FT1, FT2 make transmission request, a registration number of a registration table corresponding to the reception stations FT3-FT6 and a registration number of the registration table corresponding to its own station are designated to a 1st stage of relay station. Each relay station based on the designated registration number retrieves the registration table to make transmission to a next stage of relay station and a relay result report is returned through a relay station at transmission request sequentially based on the registration number representing its own station from the relay station of the final stage. Thus, the relay result report is returned from the final relay station directly to the relay request station.
