Abstract: The present invention relates to a method and an apparatus for transmitting and receiving a reference signal in a wireless communication system. In the method, in order to dynamically switch an uplink (UL) Demodulation-Reference Signal (DM-RS) according to the communication environment, such as CoMP and MU-MIMO, a parameter set for generation of a reference signal sequence is configured to include a Virtual Cell Identifier (VCID) parameter configured by information of a total of 9 bits and a cyclic shift hopping initial value parameter cinitCSH, which is 9-bit information representing one integer value among 510 integer values. Therefore, it may be possible to achieve dynamic transmission or reception of a reference signal and channel estimation through the dynamic transmission or reception of the reference signal even when the communication environment dynamically changes as in a Cooperative Multiple Point transmission and reception (CoMP) scenario.

Abstract: Disclosed is a rectifying device provided with a standby power reduction function. When a voltage of unsmoothed DC power, which is output from a rectifying unit that rectifies AC power, is lowered to be equal to or smaller than a discharge reference voltage at a time around a zero-crossing point of the AC power, the present invention can instantaneously discharge a capacitor, which has been charged with the unsmoothed DC power, to be synthesized with the unsmoothed DC power, and thus supply stable DC power to a load without using an electrolytic capacitor. In particular, the present invention can adjust a resistance value of a surge prevention switch connected in series with the capacitor to control a current amount flowing through the capacitor, and thus can prevent a surge voltage from being generated when charging and discharging the capacitor.
