Abstract
A method for sending a DMRS is provided. A terminal determines a first sending power for sending a first DMRS on a first frequency resource is based on control information from a network device. The first frequency resource is a frequency resource corresponding to a first CDM group among frequency resources corresponding to a first symbol. The first sending power occupies at least part of a second sending power on a second frequency resource other than the first frequency resources among the frequency resources corresponding to the first symbol. The second frequency resource is not configured for sending a second DMRS. The terminal sends the first DMRS sent by the terminal on the first frequency resource based on the first sending power.

A method for sending a Demodulation Reference Signal (DMRS), performed by a terminal, the method comprising:
- determining a first sending power for sending a first DMRS on a first frequency resource based on control information from a network device, wherein the first frequency resource is a frequency resource correspond to a first Code Division Multiplexing (CDM) group among frequency resources correspond to a first symbol, the first sending power occupies at least part of a second sending power on a second frequency resource other than the first frequency resource among the frequency resources correspond to the first symbol, and the second frequency resource is not configured for sending a second DMRS;
- and
- sending the first DMRS on the first frequency resource based on the first sending power;
- wherein the first sending power occupies XdB of the second sending power, and X is a default value or a configured value configured by the network device;
- and wherein for DMRS type 1, a value of the X is selected from 0.5, 1, 2, and 3, and for DMRS type 2, a value of the X is selected from 0.5, 1, 2, 3, and 4.77.
A method for receiving a Demodulation Reference Signal (DMRS), comprising:
- sending control information;
- and
- receiving a first DMRS at a network device from a terminal;
- wherein the first DMRS is sent by the terminal with a first sending power on a first frequency resource;
- the first sending power is determined by the terminal based on the control information;
- the first frequency resource is a frequency resource correspond to a first Code Division Multiplexing (CDM) group among frequency resources corresponding to a first symbol;
- the first sending power occupies at least part of second sending power on a second frequency resource other than the first frequency resource among the frequency resources corresponding to the first symbol;
- and the second frequency resource is not configured for sending a second DMRS,
- wherein the first sending power occupies XdB of the second sending power, and X is a default value or a configured value configured by the network device;
- and wherein for DMRS type 1, a value of the X is selected from 0.5, 1, 2, and 3, and for DMRS type 2, a value of the X is selected from 0.5, 1, 2, 3, and 4.77.
A terminal, comprising:
- a processor;
- and
- a memory for storing instructions executable by the processor;
- wherein the processor is configured to:
- determine a first sending power for sending a first DMRS on a first frequency resource based on control information from a network device, wherein the first frequency resource is a frequency resource corresponding to a first Code Division Multiplexing (CDM) group among frequency resources corresponding to a first symbol, the first sending power occupies at least part of a second sending power on a second frequency resource other than the first frequency resource among the frequency resources corresponding to the first symbol, and the second frequency resource is not configured for sending a second DMRS;
- and
- send the first DMRS on the first frequency resource based on the first sending power;
- wherein the first sending power occupies XdB of the second sending power, and X is a default value or a configured value configured by the network device;
- and wherein for DMRS type 1, a value of the X is selected from 0.5, 1, 2, and 3, and for DMRS type 2, a value of the X is selected from 0.5, 1, 2, 3, and 4.77.
