Abstract: A method for transmitting or receiving data in a communication system and a system thereof are provided to prevent ACI(Adjacent Channel Interference) from being generated between a sub MS(Mobile Station) channel and a main MS channel by transmitting or receiving data in accordance with an adaptive frequency diffusion parameter and an adaptive time diffusion parameter, determined by a CR(Cognitive Radio) communication system, and a subcarrier power allocation map, and to enhance system performance. A method for transmitting or receiving data in a communication system comprises the following several steps. Channel interference is measured in the second frequency band by using the first frequency band. A frequency diffusion parameter is determined in accordance with the measured channel interference. Channel interference is measured in the first frequency band by using the second frequency band. If link information is received from the first system in accordance with the measured channel interference, a power allocation map is determined by using the received link information. Data is transmitted/received in accordance with the determined frequency diffusion parameter and the power allocation map.

Abstract: A sub-channel allocation apparatus and method in a wireless communication system are provided to reduce a signaling overhead and increase a system throughput by reducing the system overhead. A movement speed measuring unit(501) measures a movement speed of terminals. A resource allocation period determining unit(503) selects each terminal to which sub-channel are to be allocated, and determines a resource allocation period for allocating sub-channels to the terminals. An average data amount calculating unit(505) receives the determined resource allocation period and calculates an average amount of data to be transmitted to each terminal. A resource allocating unit(507) allocates sub-channels such that the average amount of data is satisfied in consideration of channel quality information of the terminals. A transmitting unit(509) generates a control signal according to the sub-channel allocation and transmits it to the terminals.

Abstract: A method for relaying a data packet in a downlink in a wireless communication system is provided to enable RSs, appointed by a BS, to determine whether they can perform relay transmission by referring to their signal intensity if the BS appoints the RSs, which will be used in the relay transmission, and the notifies the fact, thereby removing the necessity of a special algorithm for selecting optimum RSs and reducing signaling overhead required to be transmitted through the RS. A method for relaying a data packet in a downlink in a wireless communication system comprises the following steps. A data packet is relayed by RSs(Relay Stations), which have signal intensity greater than a threshold value among RSs appointed by a BS(Base Station)(S303,S305). SSs(Subscriber Stations) determine whether to receives the data packet from the BS or from an RS, by referring to signal intensity between the SSs and the BS and signal intensity between the SSs and the RS(S307). And then, the SSs feed channel information corresponding to the determination result back to the BS and make the data packet transmitted(S309~S319).

Abstract: A composite image apparatus and a copying method thereof are provided to generate folders as many as set numbers of a user during a copying process, in order that copy target files are divisively stored in copy folders and the newly generated folders. When a user selects a copying direction and copy target files during a copying process, it is decided whether new folders are to be generated in another storage medium together with copy folders of a folder which contains the copy target files(40,42). If so, the copy folders and the new folders are made in another storage medium, then the copy target files are divisively stored in the copy folders and the new folders(44,46).
