    • The present invention relates to a method and a device for transmitting and receiving a reference signal (RS) in a wireless communication system. The present invention, in configuration of a parameter set for RS signal sequence generation for dynamically switching an uplink (UL) demodulation-reference signal (DM-RS) according to communication conditions such as CoMP, MU-MIMO and et cetera, includes a virtual cell ID parameter (VCID) consisting of a hopping initial value parameter which is 9 bit information for expressing one among 510 integers and/or 9-bit information. By doing this, dynamic transmission and reception of an RS signal and channel estimation through the same are possible although the communication conditions such as CoMP scenario dynamically vary.

    • PURPOSE: A conversion method of the block information and an apparatus using thereof are provided to perform the conversion method based on the prediction block information for increasing the image encoding efficiency. CONSTITUTION: A prediction block information input unit (1000) receives an input of the block information. Based on the information inputted from the prediction block information input unit, if a prediction mode of block is a prediction mode in a screen and the size of the block satisfies the constant condition, a reverse conversion method determining unit (1020) determines whether the block is about the luminance component or not. If the prediction mode of the block is the prediction mode in the screen, the size of the block satisfies the constant condition, and the block is about the luminance component, the reverse conversion method determining unit determines the inverse conversion method of the block as an inverse discrete sine transform (DST).
