Abstract:
PURPOSE: A relay method of a base station and a terminal is provided to execute a role of a relay station by setting a relay link between a base station and a neighbor base station. CONSTITUTION: When a backhaul link of a first base station is damaged, a downlink channel is scanned(S210). A second base station connected to the backhaul link is established(S220). A downlink parameter or an uplink parameter is acquired(S230). A ranging process is executed(S240). An operating parameter which is necessary for a relay link is comprised(S270).

Abstract:
PURPOSE: A terminal relay method is provided to offer smooth communication works by enabling a terminal to execute a base station or a relay station role. CONSTITUTION: A terminal reports the capability of the terminal for a relay station role to a base station(S410). The terminal reports the capability in an initial access process. The terminal executes the relay station role(S420~S450). A role of the relay station is determined by the base station. The terminal receives a relay setup request message from the base station. The terminal transmits the relay setup response message to the base station.

PURPOSE: A method for transmitting a broadcasting signal is provided to automatically vary a decoding method and a parallax barrier according to a broadcasting mode. CONSTITUTION: If a broadcasting program is inputted, a broadcasting service device obtains the broadcasting mode information of the corresponding broadcasting program by the analysis of the broadcasting program inputted through the program scheduler(S101,S102). The broadcasting service device encoded stream(S103). The broadcasting service device generates transport stream through a multiplexer(S104).
Abstract:
PURPOSE: A relay method of an MS(Mobile Station) is provided to enable the MS to execute a RS(Relay Station) function by using an identifier for relay data and MS data. CONSTITUTION: An MS(200) reports a basic performance including an RS function to a BS(Base Station)(120). The MS receives an AAI_MM_RS_REQ(Advanced Air Interface Multimode Relay Station Request) from the BS. The MS transmits an AI_MM_RS_RSP(Advanced Air Interface Multimode Relay Station Response) to the BS. The MS uses a FID(Flow Identifier) for separating the data of the MS from the data of the RS.
Abstract:
PURPOSE: A signaling method for executing direct communication between terminals is provided to manage flows, channels, resources, information broadcasts, and tokens by establishing a direct communication link between the terminals. CONSTITUTION: A first terminal transmits a link establishment request message for directly establishing direct communication including stream information to a second terminal(S10). The first terminal receives a link establishment response message for establishing the direct communication link establishment including flow information from the second terminal(S11). The first and the second terminal directly establish the link.
Abstract:
PURPOSE: A MIMO(Multiple Input Multiple Output) transmission method in a digital video broadcasting system and a device thereof are provided to make an average output power of a signal inputted to each antenna equal or similar to each other. CONSTITUTION: An r2n-1 and an r2n are generated by the combination of a transmission signal modulated by 16QAM(Quadrature Amplitude Modulation) and QPSK(Quadrature Phase Shift Keying) modulation through a precoding process. A value with a different component size of 16QAM and QPSK is included in the r2n-1 and the r2n. The r2n-1 and the r2n have a different PAPR (Peak-to-Average Power Ratio) value from each other. A precoded r2n-1 and r2n are alternatively inputted to an amplifier connected to each antenna for the signal inputted to an amplifier before amplification of the output signal from antenna 1 and antenna 2.
Abstract:
PURPOSE: A method for receiving and transmitting a multicast broadcast service is provided to easily recognize the MBS receiving start point of an MBS receiving device. CONSTITUTION: An MBS(Multicast Broadcast Service) transmitting device and an MBS receiving device set up the connection of MBS by using a DSx message(Dynamic Service related message)(S103). The MBS receiving device starts the reception of MBS(S107, S111). The MBS receiving device transmits an MBS-REP(MBS Report message) to the MBS transmitting device(S109). The MBS receiving device starts MBS reception through predetermined MBS connection.
Abstract:
PURPOSE: An apparatus and method for transmitting/receiving data are provided to simplify the setting process of MBS and to remove the switching process of a massage. CONSTITUTION: A data transmitting device(100) transmits a first control message which includes necessary information to a data receiving device in order to receive MBS(Multicast Broadcast Service) data(S109). The data transmitting device allocates a first carrier to the data receiving device. The data transmitting device activates a first carrier in order to transmit MBS data to the data receiving device without switching a second control message(S113). The data transmitting device transmits MBS data to the data receiving device through the first carrier(S115).
