Abstract

The present invention provides a DMRS determination method, a configuration method, a terminal and a base station. The DMRS determination method applied to the terminal includes: determining the number of symbols of the DMRS according to the transmission parameters configured by the base station, wherein the transmission parameters include: the range of the UCI load number carried by the PUCCH, the content type of the UCI carried by the PUCCH, and the number of symbols of the PUCCH , at least one of the state of the frequency hopping switch of the PUCCH and whether the PUCCH has multiplexing capability. In the present invention, the terminal can determine the number of symbols of the DMRS, thereby determining the pattern of the DMRS, and can send PUCCH information according to the pattern of the DMRS, so that the PUCCH can meet better transmission performance requirements.

Description

technical field [0001] The present invention relates to the technical field of wireless communication, in particular to a method for determining a demodulation reference signal (Demodulation Reference Signal, DMRS for short), a configuration method, a terminal and a base station. Background technique [0002] Compared with previous mobile communication systems, future 5G mobile communication systems need to adapt to more diverse scenarios and business requirements. The main scenarios of 5G include Enhance Mobile Broadband (eMBB for short), Ultra-Reliable and Low Latency Communications (URLLC for short) and massive Machine Type of Communication (mMTC for short). ), these scenarios put forward requirements for the system such as high reliability, low latency, large bandwidth, and wide coverage. [0003] There are multiple physical uplink control channel (Physical Uplink Control CHannel, PUCCH for short) formats in LTE to support different uplink control information (Uplink Co...
