Abstract

The invention discloses a demodulation reference signal transmission method, network equipment and a terminal. The method comprises: configuring a demodulation reference signal DMRS of a service channel in a mini-slot; mapping part or all of the DMRS of the service channel to the mini-slot The time-domain transmission resource corresponding to the control channel of the ‑slot is offset to the time-domain transmission resource of M time-domain symbols; M is an integer greater than or equal to 1; the DMRS of the traffic channel is transmitted through the time-domain transmission resource. In the micro-slot transmission scenario, the present invention maps all or part of the DMRS of the service channel to the time-domain transmission resource corresponding to the control channel of the mini-slot to perform transmission on the time-domain transmission resource offset by M time-domain symbols, After obtaining the transmission resource of the control channel of the mini-slot, the terminal can quickly detect the DMRS of the service channel, so as to perform channel measurement and effectively improve the data transmission rate.

Description

technical field [0001] The present invention relates to the field of communication technology, in particular to a demodulation reference signal transmission method, network equipment and terminal. Background technique [0002] Traditional fourth generation (4 th Generation, 4G) mobile communication system, the demodulation reference signal (DemodulationReference Signal, DMRS) is mainly used for channel estimation and demodulation of the traffic channel, control channel and broadcast channel, and the position of the DMRS pattern in the time domain and frequency domain is fixed. In particular, to maintain backward compatibility, the short TTI multiplexes the demodulation reference signal of the normal TTI traffic channel. [0003] Future fifth generation (5 th Generation, 5G) mobile communication system, or New Radio (NR) system, in order to support mobile broadband enhanced eMBB, ultra-high reliability and ultra-low latency communication URLLC services and other services,...
