TRANSMISSION STATION, RELAY STATION, AND RELAY METHOD

摘要

In a relay station (20), a packet fragmented by a sending station is received. The fragmented packet is selectively further fragmented into a plurality of refragmented packets. Unique information (FSN) is added to each of the refragmented packets and to a non-refragmented packet not fragmented. Each of the packets to which the unique information (FSN) has been added is transmitted to a receiving station (30). This makes it possible to prevent a confliction of information (FSN) between packets due to the packet refragmentation in the relay station (20).
