  • Publication number: 20090232060
    Abstract: A method, a wireless communication system, a communication apparatus, and a tangible machine-readable medium for establishing a routing path during a network entry process of an SS based on a multi-hop relay standard are provided. The wireless communication system comprises a BS, an SS, and an RS. The SS transmits an RNG-REQ of the SS to the RS with a ranging CID. The RS allocates an SS CID for the SS, and transmits an RNG-RSP having the SS CID to the SS with the ranging CID. Then the SS transmits an SBC-REQ with the SS CID to the BS through the RS. Finally, the BS transmits an SBC-RSP to the SS through the RS after receiving the SBC-REQ. The routing path of the SS is updated into a routing table of the RS according to one of the SBC-REQ and the SBC-RSP.
