Abstract

The embodiment of the invention discloses a method and device for processing demodulation reference signals, which are used to solve the problem that the DMRS mapping method of the traditional 4G mobile communication system cannot reduce the uplink transmission delay. The method is applied to the transmission of ultra-low-latency ULL service data. The minimum unit allocated for the ULL service data in the time domain of the transmission link is one symbol, and the minimum unit allocated for the ULL service data in the frequency domain of the transmission link is The unit is a resource grid block REB, and the method includes: the first device determines the first position of the DMRS in the transmission link; when the first device is configured with a cell-related shift and / or a symbol-related shift, the The first device determines the second position of the DMRS on the transmission link according to the first function, and maps the DMRS to the second position.

Description

technical field [0001] The present invention relates to the field of communication technology, in particular to a method and equipment for processing demodulation reference signals. Background technique [0002] The application scenarios of the fifth generation (English full name: The fifth Generation, abbreviation: 5G) mobile communication system in the future include not only enhanced mobile broadband service scenarios, but also large-scale Internet of Things connections, ultra-low latency (English full name: UltraLow ​​Latency, abbreviation : ULL) and ultra-high reliability transmission scenarios. Generally speaking, in large-scale IoT, ULL, and ultra-reliable transmission scenarios, the business model is small data packets, which require low-latency transmission. For example, remote meter reading, industrial control, etc. [0003] For ULL service transmission, the minimum unit of resource allocation in the time domain of traditional 4G mobile communication systems is a...
