PROBLEM TO BE SOLVED: To obtain a communication method for improving noise-proofing property, speeding up of transfer rate and the change of a communication mode according to a state of transmission line and a communicating party and capable of easily realizing N versus N high-speed communication. SOLUTION: This communication method is constituted by including a transfer rate deciding step to decide all carriers usable for data communication and the number of bits to be allocated to each carrier, by performing one to one training with all pieces of the communication equipment to be operated as slaves by specified communication equipment to be operated as a virtual master in the case of a high-speed mode, a mapping information deciding step to decide a common carrier usable among respective pieces of the communications equipment and the common number of bits to be allocated to each carrier as mapping information from the results obtained by individual trainings and a broadcasting step to broadcast the mapping information to all pieces of the communications equipment.
