Communication method and device

A communication method, applied to a network device, the method comprising:

• generating a reference signal;
• and
• sending the reference signal, wherein when the reference signal is not included in a channel state information-reference signal (CSI-RS) resource set that is configured with repetition on, the reference signal is to be used for radio link monitoring (RLM) measurement or beam failure detection (BFD) measurement;
• and
• wherein a CSI-RS resource in the CSI-RS resource set is a periodic resource, and a measurement period T of the CSI-RS resource is based on a preferred number of CSI-RS resource repetitions of the CSI-RS resource set and that is preferred by a communication device, a quantity of resources in the CSI-RS resource set, and a CSI-RS resource periodicity.

A communication device, comprising:

• at least one processor, configured to cause the communication device to—:
• receive a reference signal from a network device;
• in response to the reference signal not being included in a channel state information-reference signal (CSI-RS) resource set that is configured with repetition on, perform radio link monitoring (RLM) measurement or beam failure detection (BFD) measurement on the reference signal;
• and
• wherein a CSI-RS resource of the CSI-RS resource set is a periodic resource, and a measurement period T of the CSI-RS resource is based on a preferred number of CSI-RS resource repetitions of the CSI-RS resource set, a quantity of resources in the CSI-RS resource set, and a CSI-RS resource periodicity.
