  • Publication number: 20100311422
    Abstract: An apparatus and method determines neighbor Base Station (BS) information in a wireless communication system where a macro cell and a Femto cell coexist. The method includes, when a preamble scanning duration arrives, acquiring preamble information on at least one neighbor BS through preamble scanning. It is determined whether to scan a header for at least one neighbor BS among neighbor BSs for which the preamble information are acquired, in consideration of at least one of the acquisition or non-acquisition of new preamble information through the preamble scanning and a variation of an environment of a preamble acquired through the preamble scanning. And, in case that it is determined to scan the header, a header for a corresponding neighbor BS is scanned and header information of the neighbor BS is acquired.

  • Publication number: 20100210273
    Abstract: An apparatus and method for operating the femto BS includes receiving an Identification-index (I-index) and a physical cell Identifier (ID) used to generate of Inter Working Signal (IWS) contents from a macro BS. The IWS contents is generated by using the physical cell ID. The method includes performing scrambling on the IWS contents by using one of scrambling codes included in a scrambling code set of the macro BS. Thereafter, the IWS contents are transmitted.

  • Publication number: 20100056160
    Abstract: 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.

  • Publication number: 20090252080
    Abstract: Provided are an apparatus and a method for providing a relay service in a wireless communication system. The apparatus includes a modulator, an encoder, and a transmission unit. The modulator modulates a transmission signal according to a modulation degree. The encoder encodes a modulation symbol provided from the modulator using a convolution code of a ring domain. The transmission unit transmits the signal provided from the encoder to a relay station. The relay station detects a signal where signals received from different transmission ends are added in a real domain, and relays the detected signal, thereby providing a relay service without an additional time resource.

  • Publication number: 20080036762
    Abstract: The present invention relates to a system and method, which establish a plug-in relationship with a graphic program, such as Adobe Illustrator, and are adapted to reconstruct each face in three dimensions to include content designed in a two-dimensional development figure, thus converting a two-dimensional object into a three-dimensional object. In the three-dimensional design method, shapes of basic boxes are presented to a user. Dimensions corresponding to a box shape selected by the user are received. Coordinate values of a development figure are changed depending on the dimensions received from the user. A development figure suitable for the changed coordinate values is presented to the user. The design made by the user is partitioned to correspond to faces of the development figure. Three-dimensional coordinate values are set based on input coordinate values. The partitioned design is arranged on the three-dimensional coordinate values, thus generating three-dimensional data.
