Measurement and reporting method and apparatus
A measurement and reporting method and apparatus are provided, to resolve a problem that a channel resource and an interference resource conflict with a CORESET resource when SINR measurement is performed. The method includes: receiving measurement configuration information from a network device, where the measurement configuration information is used to configure a channel resource and an interference resource; and when the channel resource and the interference resource meet a preset condition, the channel resource and the interference resource are configured on OFDM symbols other than an OFDM symbol occupied by a CORESET; and performing measurement based on the configured channel resource and interference resource, the CORESET is shunned when the channel resource and the interference resource are configured, to avoid a problem that the channel resource, the interference resource, and the CORESET cannot be correctly received because the channel resource and the interference resource conflict with the CORESET resource.
