Zusammenfassung:	The present invention relates to a method and apparatus for processing DMRS signal in a LTE protocol-based base station and an user equipment. According to one aspect of the present invention, the method comprises a method for processing DMRS signal in a LTE protocol-based base station, wherein before performing OFDMA modulation, the method further comprises: - performing pattern rotation processing with OCCs on subcarriers corresponding to available DMRS antenna ports so as to reduce power imbalance between OFDM symbols generated subsequently. The solution according to the present invention may eliminate or reduce the imbalance issue between OFDM symbols of the DMRS enhancement technology in the existing LTE protocol.
