Abstract: A data transmission apparatus transmits a first control message including information needed for a data receiving apparatus to receive multicast broadcast service (MBS) data to the data receiving apparatus, and allocates a first carrier to the data receiving apparatus as a secondary carrier. The data transmission apparatus activates the first carrier without a procedure for exchanging a second control message for activating a carrier after the transmission of the first control message is achieved. The data transmission apparatus transmits MBS data to the data receiving apparatus through the first carrier.

The base station determines a first time point for multicast broadcast service (MBS)-related information and transmits the MBS-related information through a first carrier at the first time point. Also, the base station determines a second time point for transmitting a paging message to a mobile station, determines a second carrier for transmitting the paging message to the mobile station, and transmits the paging message through the second carrier at the second time point. Here, the second time point is different from the first time point.

Abstract: When zone allocation information of sub-bands is changed, a terminal receives a new MBS configuration message after a lifetime of an MBS configuration message at a time when the changed zone allocation information is received is expired. The terminal applies the changed zone allocation information at the beginning of the first MSI of the new MBS configuration message.

Abstract: A method for measuring a position includes: allocating a first ranging code and a first ranging region for a mobile station; receiving a second ranging code and allocation information on a second ranging region of the mobile station from a neighboring base station; transmitting the first ranging code and the second ranging code to the mobile station; receiving the first ranging code from the mobile station in the first ranging region; calculating a received timing adjustment value of the first ranging code; receiving a received timing adjustment value of the second ranging code from the neighboring base station; and measuring the position of the mobile station according to the received timing adjustment value of the first ranging code and the received timing adjustment value of the second ranging code. Therefore, the cost and efficiency can be improved by measuring the position of the mobile station by changing the ranging method used in the conventional system.

Abstract: Provided is a method for obtaining superframe header (SFH) information in a neighboring base station advertisement (NBR-ADV) message at a terminal. In the method, a NBR-ADV message having SFH information set per each carrier is received from a serving base station. The SFH information of each carrier is obtained from the NBR-ADV message. In the obtaining the SFH information of each carrier, SFH information of a corresponding carrier is obtained based on SFH information of a previous carrier when a predetermined field is set as a predetermined value.

Abstract: For managing MBS configuration information, a terminal decodes an MBS configuration message including configuration information for an MBS operation and a lifetime, and then decodes an MBS configuration message that is transmitted at a time that the lifetime indicates.

Abstract: A base station transmits a first message including indices of a plurality of carriers and information for the plurality of carrier to a mobile station. Also, the base station transmits a second message including a bitmap representing whether each of the plurality of carriers corresponds to a paging carrier used for transmitting a paging message, to the mobile station. The base station selects a paging transmission carrier for the mobile station from among the plurality of carriers and transmits a paging message through the selected paging transmission carrier.

Abstract: When MBS information is updated, a base station transmits a first message to a terminal. The first message includes a service flow update indicator for indicating a scheme for describing a current MBS identifier (ID) and flow ID to be updated, information on the current MBS ID and flow ID described by the scheme indicated by the service flow update indicator, and new MBS information. The terminal transmits a second message to the base station in response to the first message.

Abstract: A method in which a base station transmits a signal to a plurality of terminals in a machine to machine (M2M) communication system, the method including: allocating an M2M device group ID (MGID) that identifies a terminal group to at least one of the plurality of terminals; and sustaining the MGID when the terminal that belongs to the terminal group is in an idle state.

Abstract: Method receiving Multicast Broadcast Service (MBS) in a wireless communication system is provided. The method comprises receiving a Dynamic Service Addition (DSA) message through a primary carrier, from a Base Station (BS); switching from the primary carrier to a secondary carrier based on the DSA message; receiving an MBS Configuration message through the secondary carrier, from the BS; and receiving MBS data through the secondary carrier based on the MBS Configuration message, from the BS.

Abstract: Provided are a method for transmitting uplink data by a terminal in a mobile communication system, the method comprising: when data to be transmitted to uplink is generated in an idle mode, transmitting a ranging request message including at least one of a group identifier allocated to each terminal group to which the terminal belongs, an offline transmission indicator indicating transmission of uplink data in a state in which the terminal is not connected to a network, and uplink data, to a base station; and receiving a ranging response message confirming that the uplink data has been successfully transmitted, from the base station.

Abstract: In a method of transmitting broadcasting information, the broadcasting information is classified into fixed broadcasting information for transmitting to a fixed position of a super-frame and variable broadcasting information to be variably transmitted in the form of a broadcasting message. The fixed broadcasting information may be classified into primary broadcasting information having a short cycle and secondary broadcasting information having a long cycle.
