Abstract: An MBS(Multicast and Broadcast Service) scheduling apparatus in a BWA(Broadband Wireless Access) system and a method thereof are provided to receive a broadcasting service with minimum power consumption and simplify the structure of an RF scheduler in a base station by defining a special MBS_DATA_IE and a special MBS_MAP message in order to transmit and receive an MBS burst and the next MBS_MAP message at an identical frame. A base station decides to provide a specific MBS connection(301), and checks whether to use aligned scheduling(303). In case of using aligned scheduling, the base station schedules the next MBS frame offset for the first MBS_MAP_Aligned message(305). If the scheduled time comes(307), the base station creates the first MBS_MAP_Aligned message using an MBS_DATA_Aligned_IE, and transmits the first MBS_MAP_Aligned message at an associated frame(309). Then the base station schedules the next MBS frame offset again(311). If the scheduled time comes(313), the base station creates the second MBS_MAP_Aligned message using the MBS_DATA_Aligned_IE(315), and transmits an MBS burst and the created MBS_MAP_Aligned message at an identical frame(317).

Abstract: A system and a method for transmitting/receiving an MBS(Multicast/Broadcast Signal) in a communication system are provided to adaptively provide an MBS according to a request of a mobile WiMAX(Worldwide Interoperability for Microwave Access) communication system by generating a time stamp used for timing synchronization of the MBS in an MBS server or an ASN_GW(Access Service Network GateWay). If a communication system includes at least one region for receiving the same service and if the region includes at least one ASN_GW(430) and at least one BS(Base Station)(440-470) connected with the ASN_GW, the communication system generates the received MBS as the second MBS corresponding to information about the region. The BS generates information about a time point at which the second MBS should be transmitted. The communication system transmits the second MBS and the time point information to the BS. The generating of the time point information includes transmitting the second information requesting transmission of the first information related to a TOD(Time of Day) managed by the BS to the BS, receiving the first information from the BS, and generating the time point information by using the first information.

Abstract: An apparatus and a method for estimating location of a mobile station in a broadband wireless communication system are provided to estimate a location of the terminal station accurately without using an additional device by measuring the reception time referring the propagation delay time of a tag signal. A tag signal generator(201) outputs continuously the unique sequence granted for terminal identification by modulating the unique sequence as the bark code. A sub-carrier wave mapping device(203) maps the tag signal into a DC carrier wave. An OFDM(Orthogonal Frequency Division Multiplexing) modulator(205) creates an OFDM symbol by converting the mapped signals into time region signals through the IFFT(Inverse Fast Fourier Transform) operation. A DAC(Digital to Analog Converter)(207) converts digital signals provided from the OFDM modulator into analog signals. An RF transmitter(209) converts base band signals provided from the DAC into RF band signals, amplifies the converted signals, and transmits the signals through an antenna.
