摘要:
A method for delivering a received frame packet, to be transmitted from a packet data service node to a mobile station in a dormant state by a packet control function in a mobile communication system capable of providing data service or Push-To-Talk (PTT) service to the mobile station, via a base station connected to the packet control function. The packet control function delivers the received packet data and paging data to the base station where the mobile station in the dormant state is located. The base station forms the received packet data into an SDB (Short Data Burst), includes the SDB in a DBM (Data Burst Message) message, and transmits the DBM message to the mobile station if an analysis result of the received paging data indicates that the mobile station in the dormant state has requested fast packet paging and the base station can currently provide the fast packet paging.

摘要:
A method is provided for managing active sets of a terminal that receives a pilot channel from a base station in a mobile communication system. Reception strength of the pilot channel is measured. It is checked whether the number of active sets being managed by the terminal is greater than or equal to the predetermined maximum number of supportable active sets. It is determined whether to transmit a pilot to the base station according to the checking result.

A method and system are provided for transmitting broadcast service data in a wireless communication system using an Orthogonal Frequency Division Multiple Access (OFDMA) scheme in which data transmission is achieved through a downlink and an uplink within one frame. The system being connected to a broadcast server. The system and method include allocating a connection identifier (CID) to each broadcast service for identification of a broadcast service packet transmitted over the downlink, and transmitting broadcast service information for each broadcast service; and receiving a broadcast packet from the broadcast server, and transmitting a physical layer transmission information element (DL-MAP) including a broadcast service CID for the broadcast packet through the downlink0.

A method for receiving resources allocated from a base station by a terminal in an OFDMA mobile communication system. The method includes receiving, for a data channel, a number of first components, which indicates an amount of resources used with a first resource allocation scheme, and a number of second components, which indicates an amount of resources used with a second resource allocation scheme, from the base station over a common control channel; determining first and second identifier lengths of channel elements for the first and second resource allocation schemes according to the number of first components and the number of second components; receiving resource allocation information including an identifier indicating at least one channel element allocated to the terminal, over a data control channel using one of the identifier lengths; and transmitting and receiving data over a resource of a channel element indicated by the received identifier.

A system is provided for managing mobility of an Access Terminal (AT) in a Proxy Mobile Internet Protocol (PMIP) communication system. As the AT performs a handoff, a target Signaling Radio Network Controller (SRNC) delivers session information of the AT, acquired from a source SRNC of a source network, to a target Access Network (AN). An Authentication, Authorization and Accounting server (AAA) performs an AT access authentication process. Then, a target Access Gateway (AGW) performs a proxy registration procedure, with the target AN, and receives, from the AT, a message indicating a need to establish an interface with the HA. A Home Agent (HA) performs mobility management for the AT, receives a message for requesting proxy registration for mobility management for the AT, sends an access request message to the AAA, receives an access accept message, and sends a response message for proxy registration to the target AGW.

Disclosed is a method for allocating resources in a base station of a wireless communication system that performs communication using frequency resources. The method includes dividing subcarriers into subcarrier sets each including a predetermined number of consecutive subcarriers, and generating a resource index table mapped to consecutive indexes such that a distance between subcarriers in the subcarrier sets is maximized; and determining an amount of resources to be transmitted through a downlink according to a channel condition, for data to be transmitted to each terminal, and allocating resources to the terminal using the index value in the resource index table.

A retransmission method and apparatus in a multi-hop broadband wireless communication system are provided, in which if there is a failed data block among data blocks received from a source node, a Relay Station (RS) transmits a feedback message requesting retransmission of the failed data block to the source node, transmits a successfully received data block to a destination node, receives a retransmitted data block for the failed data block from the source node, transmits the received retransmitted data block to the destination node, receives from the destination node a feedback message about data blocks transmitted to the destination node, and transmits the feedback message to the source node.

An apparatus and method for transmitting/receiving data in a mobile communication system using multiple antennas are provided. A receiver estimates a fading channel of received data, selects a weight set relative to a maximum data transmission rate from at least one weight set with elements of a plurality of orthogonal weight vectors, and transmits feedback information including the selected weight set and channel-by-channel state information to a transmitter. The transmitter demultiplexes data to be transmitted on a basis of the feedback information into at least one sub-data stream, multiplies each sub-data stream by an associated weight, and transmits the data.
摘要:
An apparatus and method for determining a transmission unit for data stream transmission in a wireless communication system in which multiple transmission and reception antennas are used and a receiver provides information on a data stream to be transmitted through a transmission unit. A fading estimator calculates fading values from the multiple transmission antennas to the multiple reception antennas. A channel quality estimator reverse-orders combined weights for multiple transmission units based on the fading values from the multiple transmission antennas to the multiple reception antennas, successively selects transmission units for data stream transmission among the reverse-ordered transmission units, determines a modulation and coding scheme (MCS) for each of the selected transmission units, and feeds back the MCS to a transmitter.
