| 20080240009 | SYSTEM AND METHOD FOR DATA TRANSMISSION/RECEPTION IN A COMMUNICATION SYSTEM - Disclosed is a system and method for transmitting data based on an operational state of a mobile station in a communication system. The method includes, when detecting a low battery state of the mobile station, storing one or more data packets to be transmitted to the mobile station, extracting at least one data packet, which has a transmission delay time larger than a difference between a maximum delay time and preset margin, from the one or more stored data packets, and transmitting at least a part of the extracted at least one data packet to the mobile station by using a resource allocated to the mobile station. | 10-02-2008 |
| 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 |
| 20080317033 | Apparatus and method for requesting bandwidth allocation and allocating bandwidth in a communication system - A method and apparatus for requesting bandwidth allocation and allocating a bandwidth in response to the request in a communication system are provided, in which an mobile station detects a second CID requiring bandwidth allocation, the second CID being different from a first CID included in a MAC header, generates a grant management subheader including an order field and a bandwidth field, the order field being for writing a rank of the second CID in a CID list listing CIDs of the mobile station according to a predetermined criterion and the bandwidth field being for writing a bandwidth required for the second CID, concatenates the grant management subheader to the MAC header, and transmits the concatenated MAC header and grant management subheader to a base station to request bandwidth allocation for the second CID. | 12-25-2008 |
| 20090022101 | Method and system for transmitting/receiving data in communication system - Disclosed is a method and apparatus for allocating a bandwidth in a communication system. The method includes the steps of checking the number of mobile stations that fall within a cell under the control of an relay station and have data to be transmitted to a base station, determining a bandwidth allocation period for data transmission corresponding to the checked number of mobile stations, and transmitting a bandwidth allocation message at intervals of the determined bandwidth allocation period. | 01-22-2009 |
| 20090036050 | Apparatus and method for controlling power in wireless communication system using relaying - An apparatus and method for controlling a mode transition of a mobile station (MS) in a relay station (RS) in a wireless communication system are provided, in which upon receipt of a mode transition request signal from at least one MS within a service area of the RS, the RS determines whether to approve the mode transition request, sets management information for the mode transition of the MS, if the mode transition request of the MS is approved, and transmits the management information to the MS. | 02-05-2009 |
| 20090059838 | Methods and apparatuses for efficiently using radio resources in wireless communication system based on relay station (RS) - Methods and apparatuses for efficiently using radio resources in a wireless communication system based on a relay station are provided. An operating method of a relay station (RS) for efficiently using radio resources in a wireless communication system based on the RS. The method includes setting a call with a sending terminal; checking whether a receiving terminal of the sending terminal travels in the same RS cell, in a different RS cell of the same base station (BS) cell, or in a different cell of a neighbor BS; and checking a destination address of a data and relaying the data to the receiving terminal according to a result of the checking. | 03-05-2009 |
| 20090075587 | Apparatus and method for scheduling in a multi-hop relay wireless communication system - A multi-hop relay wireless communication system is provided. A base station (BS) includes a communication unit for receiving information on a received signal level and information on an interference node from mobile stations (MSs), and a scheduler for classifying a type of each MS by using the received signal level information and the interference node information and for performing differentiated scheduling according to the MS type. | 03-19-2009 |
| 20090186594 | SYSTEM AND METHOD FOR PROVIDING AN EMERGENCY SERVICE IN A COMMUNICATION SYSTEM - A system and method for providing an emergency service in a communication system are provided. The method includes transmitting a request message for requesting connection setup for service provision from a first station to a second station, the request message including a first indicator indicating an emergency service; receiving a response message in response to the request message by the first station from the second station, the response message including service flow connection information for provision of the emergency service and a second indicator indicating that it is a response to the request message, acquiring the service flow connection information from the response message and transmitting a message acknowledging acquisition of the service flow connection information to the second station, and setting a connection for providing the emergency service. | 07-23-2009 |
| 20090186595 | SYSTEM AND METHOD FOR PROVIDING AN EMERGENCY SERVICE IN A COMMUNICATION SYSTEM - A system and method for providing an emergency service in a communication system is provided. A method for providing an emergency service by an idle mode Mobile Station (MS) in a communication system includes receiving, from a Base Station (BS), a broadcast message including information on a time duration in which an emergency service message will be transmitted after waking up at a start timing point of a paging listening interval, transitioning into an idle state when a start timing point of the time duration in which the emergency service message will be transmitted is later than a timing point at which the paging listening interval is terminated, and waking up at the start timing point of the time duration in which the emergency service message will be transmitted after transitioning into the idle state. | 07-23-2009 |
