  • Apparatus and method for relaying neighbor base station information in a multi-hop relay wireless access communication system
    Publication number: 20070060049
    Abstract: An apparatus and method for relaying neighbor BS in a multi-hop relay broadband wireless access (BWA) communication system are provided. In the BWA communication system, a BS transmits a neighbor BS advertisement message to a relay station (RS) within a cell area of the BS. The RS configures a relay neighbor BS advertisement message by eliminating unavailable neighbor BS information from the neighbor BS advertisement message, and broadcasts the relay neighbor BS advertisement message in a cell area of the RS.

  • Channel interleaving/deinterleaving apparatus in a communication system using low density parity check code and control method thereof
    Publication number: 20070033486
    Abstract: A channel interleaving method and apparatus in a communication system using a low density parity check (LDPC) code. Upon receipt of information data bits, an encoder encodes the information data bits into an LDPC codeword using a predetermined coding scheme. A channel interleaver interleaves the LDPC codeword according to a predetermined channel interleaving rule. A modulator modulates the channel-interleaved LDPC codeword into a modulation symbol using a predetermined modulation scheme.

  • System and method for notifying completion of network re-entry procedure in a communication system
    Publication number: 20070010262
    Abstract: Provided is a system and method for notifying completion of a network re-entry procedure in a communication system. In the system, a mobile station (MS) completes the network re-entry procedure with a base station (BS), and then notifies the completion of the network re-entry procedure to the BS.

  • System and method for state synchronization between a base station and a mobile station in a mobile communication system
    Publication number: 20070010267
    Abstract: A system and method for state synchronization between a base station and a mobile station in a mobile communication system. A count value indicative of a state change of the base station is received. The received current count value is compared with a previous count value previously received and stored. If the current count value is different from the previous count value, the mobile station performs a network entry procedure with the base station.

  • Apparatus and method for generating low density parity check code using zigzag code in a communication system
    Publication number: 20060190801
    Abstract: A method for generating a low-density parity check (LDPC) code supporting various code rates. The method includes finding a plurality of parity check matrixes showing the best performance at a predetermined code rate; matching the parity check matrixes in terms of the number of ‘1’s per row in units of sub-matrixes of each of the matrixes; and converting the plurality of parity check matrixes into one matrix, and combining punctured zigzag codes generated for every code rate into one punctured zigzag code.
