Title:
METHOD AND APPARATUS FOR TRANSMITTING REFERENCE SIGNAL
Document Type and Number:
WIPO Patent Application WO/2021/030983
Kind Code:
A1
Abstract:
The present application provides a method and apparatus for transmitting a reference signal capable of solving the problem of insufficient DMRS transmission resources, so as to improve the reliability of transmitting the DMRS. The method and apparatus can be applied to 4G or 5G communication systems, such as LTE and NR. The method comprises: a network device sends a demodulation reference signal to a terminal device on a first symbol. The first symbol is determined by symbols respectively occupied by a synchronization signal block, a system message and a data channel. The first symbol can be a symbol, that is not occupied by the synchronization signal block and the system message, in the symbols occupied by the data channel.
