摘要:
A group communication method of a terminal is provided. The terminal establishes a group call connection with a first base station belonging to a group call zone, and receives group call data from the first base station. When moving to the coverage area of a second base station belonging to the group call zone, the terminal receives group call data from the second base station.

A method of setting a cycle of a low-duty mode in a femto base station is provided. The cycle of the low-duty mode has a pattern in which an available interval and an unavailable interval repeatedly appear, and the available interval is set to include a paging listening interval of a paging cycle. A method of setting a cycle of a low-duty mode in a femto base station having a service area overlapping with that of a macrocell is provided. An unavailable interval is set by taking the overlapping degree of the service area of the femto base station with the macrocell into consideration. A method of setting a cycle of a low-duty mode in a plurality of femto base stations operated in the low-duty mode is provided. The same cycle can be set for a plurality of base stations.
摘要:
A method for a base station supporting multicarrier operation to transmit a paging message is provided. 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.
摘要:
A method of managing carriers in a terminal of a multi-carrier system is provided. The method includes switching from a primary carrier to an MBS carrier for an MBS, receiving MBS-associated data from a base station through the MBS carrier, returning to the primary carrier from the MBS carrier after receiving the MBS-associated data, and communicating with the base station through the primary carrier.
摘要:
A method for managing radio resources of a base station is provided. The method includes evaluating a radio environment between a base station and at least one neighboring base station or a radio environment between the base station and terminals connected to the base station, if the evaluated radio environment does not meet predetermined criteria, selecting a new radio resource, deactivating the existing radio resource, and reactivating the new radio resource. Accordingly, the radio resources can be efficiently managed.
摘要:
An MBS transmitting apparatus allocates a plurality of time intervals of an MBS transmission carrier to an MBS region and a non-MBS region and generates region allocation information of the MBS region and the non-MBS region. The MBS transmitting apparatus allocates the time intervals, allocated to the MBS region, to one or more MBS zones and generates MBS zone allocation information of the one or more MBS zones. The MBS transmitting apparatus transmits the region allocation information and the MBS zone allocation information and transmits the MBS data through the time intervals allocated to the MBS region.
摘要:
A method and apparatus for controlling power for uplink are provided. When a base station is moving or unable to communicate with others, at least one interference amount is estimated for a neighboring base station based on a path gain between a terminal and the neighboring base station and a transmission power of each encoding packet size and transmission format included in a candidate group related to scheduling transmission power parameters. A target interference amount is determined based on an interference amount control value and an initial target interference amount according to a processing load of a serving base station, and one interference amount is selected from estimated interference amounts based on the target interference amount. The terminal determines the transmission power based on an encoding packet size and a transmission format corresponding to the selected interference amount.
摘要:
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.
摘要:
A base station allocates a paging group to a mobile station. The base station transmits, to a mobile station, a first message including indices of a plurality of carriers and information for the plurality of carriers and a second message including paging group information representing whether each of a plurality of carriers supports each of one or more paging groups. Then, the base station selects a paging transmission carrier for the mobile station from among at least one paging carrier corresponding to the paging group allocated to the mobile station and transmits the paging message through the paging transmission carrier.
摘要:
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.
