Wireless communication method and apparatus thereof

A wireless communication apparatus for relaying a packet, the apparatus comprising:

• a reception unit that receives the packet wirelessly;
• a header recognition section that recognizes a header included in the packet received by the reception unit;
• a packet determining section configured to determine whether the packet received by the reception unit is directed to the wireless communication apparatus itself;
• a table to recognize a next transmission destination based on a destination of the packet received by the reception unit;
• a relay station packet determining section configured to determine a packet to be relayed through the table and the header recognition section;
• a sequence number management section configured to determine sequence numbers of the packet to be relayed by the reception unit and the packet determined by the packet determining section and to manage the determined sequence numbers, wherein a reception completion confirmation packet into which an updated sequence number is inserted is transmitted by the wireless communication apparatus, if the sequence number management section detects whether the received packet is one in which a sequence number is to be updated;
• and
• a security table to store security data for a recognition of a communication counterpart, wherein the header recognition section neither transmits the corresponding packet from the wireless communication apparatus nor a reception completion confirmation packet, if the received packet is from a station from which a packet reception is not required as determined by security information included in the received packet and information stored in the security table.
