Abstract: Example interference measurement methods and apparatus are described. One example method includes that a terminal device receives configuration information of an interference measurement resource from a network side device. The terminal device performs first interference measurement by using a first measurement resource. The first measurement resource is a proper subset of the interference measurement resource. A quantity of resource elements of the first measurement resource that are located in a same symbol is M, where M≥2. A spacing in frequency domain between two adjacent resource elements of the M resource elements of the first measurement resource that are located in the same symbol is more than one subcarrier.

Abstract: This application discloses a resource indication method, a network device, and a terminal device, to improve utilization of a resource mapped to a DMRS port. The method includes: sending, by a network device, configuration information to a terminal device, so that the terminal device determines, based on the configuration information, that a second resource in first resources is used to transmit first information or that a third resource in first resources is not used to transmit first information, where the first resources are resources mapped to a DMRS port. In this way, the terminal device can multiplex the resources mapped to the DMRS port. When some of the first resources are not used to transmit a DMRS, the resources may be indicated to determine whether the resources may be used to transmit the first information, for example, the first information may be data, control information, or other information different from DMRS information, thereby ensuring maximum use of the resources mapped to the DMRS port, and improving resource utilization.
