Abstract: Disclosed are a method and an apparatus for transmitting and receiving a synchronization signal in a communication system. According to an exemplary embodiment of the present disclosure, a method of transmitting a first synchronization signal, performed by a base station in the communication system, may comprise generating a base sequence; generating a modified sequence by inverting polarity of the base sequence; mapping the base sequence and the modified sequence to a first frequency region having a frequency higher than a center subcarrier and a second frequency region having a frequency lower the center subcarrier, so that the base sequence and the modified sequence are symmetric centering the center subcarrier located at a center frequency of a frequency domain of the synchronization signal; and transmitting the synchronization signal comprising the base sequence and the modified sequence to a terminal. Therefore, performance of the communication system can be improved.

Abstract: The present disclosure relates to a mixed phenomena expressing method for expressing physical phenomena in a mixed reality and a mixed reality apparatus for performing the method. To be more specific, the physical phenomena expressing method configures a scene which may enhance a context or a realism to have the same level as the face-to-face situation using a scene configuration of the input image collected from the sensor to provide a service of a mixed reality and a physics/physical property analysis of a target object included in the input image.
