    摘要: A method for transmitting reference signals in a radio communication system in which a frequency band is divided into a plurality of sub-frequency bands. The reference signals are transmitted through at least one of the plurality of sub-frequency bands, and data signals are transmitted through the plurality of sub-frequency bands except for the at least one of the plurality of sub-frequency bands. The method includes the steps of: determining a reference signal pattern representing positions of the at least one of the plurality of sub-frequency bands through which the reference signals are transmitted in consideration of a preset time and a preset bandwidth; generating the reference signals using a PN code and a Walsh code; and transmitting the reference signals through the sub-frequency bands corresponding to the reference signal pattern.

    摘要: Provided are an ARQ apparatus and method for a multihop system in a broadband wireless access communication system. The ARQ method of a relay includes determining if the relay successfully receives specific data from a source and transmitting the specific data to a destination; receiving feedback data from the destination and determining if the destination successfully receives the specific data; generating feedback data including data indicating if the relay and the destination successfully receive the specific data, and outputting the feedback data to the source; and retransmitting the specific data, when the relay successfully receives the specific data but the destination fails to receive the specific data. Accordingly, when the MH-BTS successfully receives the data from the source but the destination fails to receive the data, the source does not retransmit same data to the MH-BTS.

    摘要: A method and apparatus of supporting a fast handover in a transport layer is provided. In a network using an SCTP (Stream Control Transmission Protocol), an MN (Mobile Node) acquires a first new IP (Internet Protocol) address after a first handover to a first new network area, stores information about the first handover to the first new network area, and sends (i.e., transmits) a first handover message including the new IP address to a CN (Correspondent Node). If a second handover to a second network area is required, the MN performs the second handover even if a response message for the first handover message has not been received, acquires a second new IP address, stores information about the second handover, and sends a second handover message including the second new IP address to the CN.

    摘要: Provided are an Automatic ReQuest (ARQ) apparatus and method for a multihop system in a broadband wireless access communication system. When the number of ACK MAPs in ARQ feedback information element of ARQ feedback message transmitted from a destination or Multi-Hop Base Transceiver Station (MH-BTS) is not zero, and it is determined that the destination or a lower MH-BTS successfully receives data corresponding to Block Sequence Number (BSN), the BSN is updated with a BSN successfully received at the destination or the lower MH-BTS, and is transmitted to the upper MH-BTS or the source. Accordingly, when the MH-BTS successfully receives the data from the source but the destination fails to receive the data, the source does not retransmit same data to the MH-BTS.
