| 20080233989 | APPARATUS AND METHOD FOR TRANSMITTING/RECEIVING CHANNEL QUALITY INFORMATION IN A COMMUNICATION SYSTEM - An apparatus and method for transmitting/receiving a Channel Quality Information (CQI) in a communication system are provided. A Mobile Station (MS) receives first information indicating a representative MS selected from a group of MSs located within a preset range and in similar channel statuses, the group including the MS, determines from the first information whether the MS is designated as the representative MS, and transmits a CQI of the MS as a representative CQI of the MSs included in the group to a Base Station (BS), if the MS is designated as the representative MS. | 09-25-2008 |
| 20080242291 | Method and system for transmitting/receiving data in communication system - Disclosed is a method and system for transmitting and receiving data in a communication system. The system includes a base station, and a relay station connecting the base station with at least one mobile station. The base station transmits data for a plurality of mobile stations to the relay station, and transmits the data to at least one mobile station belonging to the base station from among the plurality of mobile stations. The relay station receives the data from the base station, and transmits the data to at least one mobile station belonging to the relay station from among the plurality of mobile stations in the same interval as an interval where the base station transmits the data to the mobile station. | 10-02-2008 |
| 20090196257 | APPARATUS AND METHOD FOR PERFORMING HANDOVER OF TERMINAL IN WIRELESS COMMUNICATION SYSTEM - Provided are an apparatus and a method for performing a handover of a terminal in a wireless communication system. In the method, a ranging code is transmitted to a target base station on which a handover is to be performed. A ranging response message comprising Connection Identification (CID) update information is received from the target base station together with resource assignment information for transmission of a ranging request message. Therefore, fast resumption of downlink data reception of the terminal can be supported through fast CID update during a handover. | 08-06-2009 |
| 20090207809 | APPARATUS AND METHOD FOR REDUCING HANDOVER DELAY IN BROADBAND WIRELESS COMMUNICATION SYSTEM - A method and an apparatus for reducing a handover delay in a broadband wireless communication system are provided. In a method for operating a terminal to reduce a handover delay in a broadband wireless communication system, a handover procedure is performed with a serving Base Station (BS) to obtain a dedicated ranging code and a Connection ID (CID). The dedicated ranging code is transmitted to one or more target BSs using the CID. Whether the dedicated ranging code is received is determined. Therefore, a handover delay and a chance of malfunction can be reduced. | 08-20-2009 |
| 20100056160 | Appatatus and method for transmitting inter-working signal in wireless communication system - A Base Station (BS) includes an apparatus and method for transmitting cell information. The BS is in the a communication system of a small cell size in a wireless communication environment in which a communication system of a large cell size and the communication system of the small cell size are hierarchically constructed in the same area. The method includes confirming reference signal transmission information for transmitting a reference signal including its own cell information, if a reference signal transmission interval arrives according to the reference signal transmission information, transmitting the reference signal through an operation frequency of a macro BS of the large cell size including the BS itself, and, if it is not the reference signal transmission interval, providing service through its own operation frequency or operating in a power saving mode. | 03-04-2010 |
| 20100124179 | Method and apparatus for identifying types and access modes of neighbor cells in femtocell environment - In a mobile communication system including macro cells and femtocells, a neighbor cell identification method includes: transmitting, by a neighbor cell that is a macro cell or a femtocell, a neighbor cell identifier containing information regarding the type and access mode of the neighbor cell to a user equipment. The user equipment identifies, after receiving the neighbor cell identifier the type and access mode of the neighbor cell. The user equipment also accesses the neighbor cell according to the identification result. | 05-20-2010 |
| 20100177738 | METHOD AND APPARATUS FOR OPERATING MOVING NETWORK IN A MOBILE COMMUNICATION SYSTEM - A method and an apparatus for operating a moving network in a mobile communication system are provided. A method of a Base Station (BS) for operating a Moving Network (MN) includes determining an operation mode of the MN in a cell by collecting information of the cell, and transmitting the determined operation mode to the MN. The operation mode includes at least one of an Operation ON mode in which the MN maintains links to Mobile Stations (MSs) in a service coverage area of the MN, and an Operation OFF mode in which the MN turns off the links to the MSs in the service coverage area of the MN. | 07-15-2010 |
| 20100260156 | Apparatus and method for transmitting system information block in a broadband wireless communication system - An operation method of the femto BS includes configuring a subframe set including at least two types of subframes among subframes having predefined different structures, and, if a duration of a subframe carrying the subframe set arrives, transmitting one of the subframes included in the subframe set according to predefined order. The subframes having the predefined different structures include a first type subframe including a synchronization signal and a Master Information Block (MIB), a second type subframe including the synchronization signal, a third type subframe including the synchronization signal and system information, a fourth type subframe including the synchronization signal, the MIB, and the system information, and a fifth type subframe including the system information. | 10-14-2010 |
| 20110103282 | METHOD AND DEVICE FOR CONTROLLING HAND-OVER MESSAGE TRANSMISSION POWER IN A MOBILE COMMUNICATIONS SYSTEM - The present invention relates to a method and a device for controlling the hand-over message transmission power of a mobile station in a mobile communication system. The present invention comprises the processes of: acquiring uplink data relating to a hand-over target base station; using the uplink data to determine the maximum transmission power of a hand-over ranging message; and transmitting a hand-over ranging message having a power level below the determined maximum transmission power to the hand-over target base station. | 05-05-2011 |
