Reference signal transmission method and device

2-6. (canceled)

A wireless communication method, comprising:

• receiving, by a user equipment (UE), indication information transmitted by a base station through a higher layer signaling, wherein the indication information indicates whether a phase noise reference signal is contained in a physical downlink shared channel;
• and
• processing the phase noise reference signal.

8-11. (canceled)

A wireless communication method, comprising:

• determining, by a base station, that an index of a modulation and coding scheme of downlink data is greater than or equal to five;
• and
• transmitting, by the base station and in response to the determining, a phase noise reference signal to a user equipment (UE).

13-17. (canceled)

A reference signal transmission device, applied to a base station, comprising:

• a processor configured to:
• transmit indication information to a user equipment (UE) through a higher layer signaling, wherein the indication information indicates whether a phase noise reference signal is contained in a physical downlink shared channel.

19-23. (canceled)

25-28. (canceled)

30-38. (canceled)

A wireless communication method, comprising:

• determining, by a base station, that an index of a modulation and coding scheme of downlink data is greater than or equal to ten;
• and
• transmitting, by the base station and in response to the determining, a phase noise reference signal to a user equipment (UE).
