    摘要: A handover apparatus and method for a multi-hop system in a BWA communication network are provided. In a handover system supporting multi-hop system in a BWA communication network, a BS periodically broadcasts a message with neighboring BS/RS information. When a new BS or RS needs to be added, an RS periodically broadcasts the broadcast message received from the BS with information about the new BS or RS. An MS receives the broadcast message from the RS and requests information about BSs or RSs to which the MS can perform a handover by notifying candidate BSs or RSs for the handover. The candidate BSs or RSs may include a BS or RS not included in the broadcast message, if the MS detects the BS or RS by scanning. The MS selects a target BS or RS based on the BS or RS information received from the BS, and performs the handover to the target BS or RS.

    摘要: A method and apparatus for supporting a seamless handover in a transport layer is provided. In a network using an SCTP, an MN notifies a CN of a handover after the handover occurs. The MN receives a handover confirm message from the CN and sends a response message for the handover confirm message to the CN. The MN checks a recipient IP address at which data is received from the CN. If the recipient IP address is a new IP address, the MN changes a primary IP address of the MN to the new IP address. If the recipient IP address is the primary IP address, the MN maintains the primary IP address.

    摘要: Disclosed is a method for controlling transmission power to be allocated to sub-carrier signals in a cellular communication system capable of dividing a frequency band into a plurality of sub-carrier bands and multiplexing the sub-carrier signals of the sub-carrier bands based on multiple frequency reuse factors. The method comprises the steps of determining a target Signal to Interference and Noise Ratio (SINR) of sub-carrier signals employing a first frequency reuse factor selected from the multiple frequency reuse factors; determining a weight of the sub-carrier signals employing the first frequency reuse factor and a weight of other sub-carrier signals employing frequency reuse factors other than the first frequency reuse factor corresponding to the target SINR; and applying the determined weights to the sub-carrier signals employing the first frequency reuse factor and the sub-carrier signals employing frequency reuse factors other than the first frequency reuse factor, thereby controlling the transmission power.

    摘要: A system and method for transmitting control information and data to a mobile station in a communication system using adaptive antenna technology defined in a broadband wireless communication system. In a method for transmitting and receiving information data in the wireless communication system, a base station separates information data to be transmitted into control information and user data, applies different modulation and coding schemes to the control information and the user data, and transmits the information data to an associated mobile station. The mobile station identifies the modulation and coding schemes of the information data received from the base station and demodulates a total of the information data according to the modulation and coding schemes, or independently demodulates the control information and the data according to the modulation and coding schemes.

    摘要: A method for providing a single-frequency network (SFN) service between a base station (BS) and a mobile station (MS) in a wireless communication system. The BS sets a first segment indicator in a medium access control (MAC) message field before transmission, if a resource allocation scheme corresponds to general data transmission. The BS sets a second segment indicator in the MAC message before transmission, if the resource allocation scheme corresponds to single frequency-based data transmission. The MS receives the MAC message from the BS, and performs renumbering according to the first segment indicator or the second segment indicator included in the received MAC message.

    摘要: A radio communication system divides an entire frequency band into a plurality of subcarrier bands, forms a symbol from signals on the subcarrier bands, forms a frame from a plurality of symbols, transmits a pilot signal within symbols in a predetermined position of the frame, and transmits a data signal within symbols other than the symbols for transmitting the pilot signal. A transmitter generates the pilot signal, performs an inverse fast Fourier transform (IFFT) on the pilot signal by applying an IFFT size which is less than an IFFT size applied to the data signal, and transmits the IFFT-processed reference signal to a receiver.
