Abstract

In the embodiment of the present invention, by indicating a double-codeword transmission mode and two single-codeword transmission modes, wherein the two single-codeword transmission modes are distinguished by using the new data indication NDI, so that the available state value of the reference signal configuration increases, and then can support Higher-order (such as 16-layer, 24-layer) MU-MIMO can significantly improve the spectral efficiency of the system, and also increase the flexibility of MU-MIMO configuration and improve the effectiveness of resource scheduling.

Description

technical field [0001] The present invention relates to the field of communication technologies, in particular to a reference signal configuration method and device. Background technique [0002] In the long-term evolution technology (English: Long Term Evolution; abbreviation: LTE) system, the multiple-input multiple-output (English: Multi-input Multi-output; abbreviation: MIMO) technology supports spatial multiplexing of multi-layer data streams. The demodulation reference signal (English: Demodulation Reference Signal; abbreviation: DMRS or DM-RS) corresponding to the stream needs to maintain orthogonal (English: Orthogonal) or semi-orthogonal (English: Semi-orthogonal) characteristics to avoid interference between data streams . For example, frequency division multiplexing and orthogonal masking (English: Orthogonal Cover Code; OCC) are used between multiple DMRSs corresponding to multi-layer data streams of a single user to realize completely orthogonal DMRS configurat...
