Abstract

See full text

Disclosed are a method for transmitting a demodulation reference signal (DMRS), a base station and a user equipment, related to the LTE Advanced system. The method for transmitting the DMRS disclosed in the present document includes: a base station transmitting a plurality of demodulation reference signal (DMRS) ports through frequency division multiplexing (FDM) and/or code division multiplexing (CDM) and/or time division multiplexing (TDM). The embodiment of the present invention further discloses a base station and a user equipment. The technical scheme of the present application greatly boosts the DMRS demodulation performance, especially taking into account its use in the 256QAM modulation method in future, balances interpolation performance of various PRB Pairs in one sub-frame, and it avoids a collision between a DMRS and a RCRS, a PSS/SSS as well as a CSI-RS.
