Title:
DMRS PROCESSING METHOD, APPARATUS, SYSTEM, DEVICE, TERMINAL AND STORAGE MEDIUM
Document Type and Number:
WIPO Patent Application WO/2020/063464
Kind Code:
A1
Abstract:
Disclosed herein are a DMRS processing method, an apparatus, a system, a device, a terminal and a storage medium. The DMRS processing method comprises: acquiring physical resources to be configured, the physical resources to be configured comprising a first category of channel resources and a second category of channel resources; configuring M first demodulation reference signal ports for the first category of channel resources and N second demodulation reference signal ports for the second category of channel resources; the first demodulation reference signal is used for demodulating the first category of channel resources, and the second demodulation reference signal is used for demodulating the second category of channel resources; an association relationship exists between at least one of the M first demodulation reference signal ports and at least one of the N second demodulation reference signal ports, and M and N are positive integers.
