Reference signal indication method, network device and terminal device

A reference signal indication method, applied to a terminal device side and comprising:

• receiving reference signal indication information transmitted by a network device, wherein, the reference signal indication information is used to indicate a target reference signal pattern to be used in later transmission occasions, and the target reference signal pattern is a reference signal pattern selected from multiple predefined reference signal patterns;
• and
• in a case that the reference signal indication information is not received, determining the target reference signal pattern to be a default reference signal pattern, and transmitting corresponding reference signals in transmission resources corresponding to the default reference signal pattern;
• or
• in a case that the reference signal indication information is not received, determining the target reference signal pattern to be a reference signal pattern indicated by a previous piece of reference signal indication information received by the terminal device, and transmitting corresponding reference signals in transmission resources corresponding to the reference signal pattern indicated by the previous piece of reference signal indication information received by the terminal device.

A network device, comprising:

• a configuration circuit, configured to select a target reference signal pattern to be used for a terminal device in later transmission occasions, wherein the target reference signal pattern is a reference signal pattern selected from multiple predefined reference signal patterns;
• a first processing circuit, configured to not transmit reference signal indication information to the terminal device in a case that the target reference signal pattern is a default reference signal pattern;
• or
• a second processing circuit, configured to not transmit the reference signal indication information to the terminal device in a case that the target reference signal pattern is the same as a reference signal pattern indicated by a previous piece of reference signal indication information.
