1. A method for channel and interference measurement, applied to a terminal device and comprising:
receiving a first group of reference signal resources, wherein the first group of reference signal resources is used to measure a channel corresponding to a first reference signal resource in the first group of reference signal resources and a first interference corresponding to the first reference signal resource, the first interference represents an inter-beam interference;
receiving a second group of reference signal resources having an association relationship with the first group of reference signal resources, wherein the second group of reference signal resources is used to measure a second interference corresponding to the first reference signal resource, the second interference represents a neighboring-cell interference and measuring, at least one reference signal resource in the second group of reference signal resources partially or completely overlaps with at least one reference signal resources in the first group of reference signal resources;
measuring, based on quasi co-location (QCL) information of the first reference signal resource by using the first group of reference signal resources, the channel corresponding to the first reference signal resource and the first interference corresponding to the first reference signal resources; and
measuring, based on the QCL information of the first reference signal resource by using the second group of reference signal resources, the second interference corresponding to the first reference signal resource.
