<p>A method for asynchronous communication through an IEEE 1394 bus (radio bus) in a radio environment by allowing a hub station to integratedly manage information unique to radio. When an operating-state packet used by a radio terminal to report the reception state of another radio terminal is received, a request for transmission of an asynchronous packet is sent along with the radio terminal identifier of the receiver to a hub station. The hub station performs, according to the information, allocation of transaction label, selection of optimum modulation/coding rate, judgment of relay, determination of polling priorit, and reports the results to the radio terminal through a polling packet representing the transmission right of an asynchronous packet. The radio terminal that obtains the transmission right and the radio terminal, receiver, perform transmission/reception according to the information, thereby transmitting an asynchronous packet in requisite minimum procedures.</p> |
