The embodiment of the invention provides a DMRS configuration method and device in 5G communication and a terminal. The method comprises the steps of: determining a first DMRS configuration based on atime-frequency resource block of data transmission and an Advanced DMRS configuration state; and issuing the first DMRS configuration to a terminal, so as to enable the terminal to correct the frequency domain density and / or the time domain density of the first DMRS configuration according to a pre-acquired pilot frequency density parameter to obtain a second DMRS configuration. According to theinvention, the influence of channel tracking and pilot density on data demodulation is considered, the pilot frequency density parameter is added to determine pilot frequency resources, the channel estimation accuracy and the data code rate can be balanced, the problem that the channel estimation accuracy and the data transmission reliability can be influenced due to the fact that DMRS density isnot considered in the prior art is solved, and the effects of adapting to various channel environments and achieving the optimal data demodulation correctness are achieved.
Description
technical field [0001] The embodiments of the present invention relate to the technical field of communication, and in particular to a DMRS configuration method, device and terminal in 5G communication. Background technique [0002] With the commercialization of the fourth-generation mobile communication technology and the continuous growth of mobile services, research work on the fifth-generation mobile communication technology (5th-Generation, 5G) has been started worldwide. 5G is a multi-technology fusion communication that meets the needs of a wide range of data and connection services through technological change and innovation. In the RAN#71 meeting, the 3rd Generation Partnership Project (3rd Generation Partnership Project, 3GPP) established a research project (study item, SI) on 5G new air interface research. According to 5G's division of vertical services, 3GPP mainly focuses on enhanced mobile broadband (eMBB), ultra-reliable low-latency communications (URLLC) and...
