Abstract: This application provides an interference measurement method and an apparatus. The interference measurement method includes: A network device sends first indication information to a terminal device. The first indication information indicates the terminal device to measure signal quality of a first signal. The network device sends the first signal to the terminal device by using N analog beams. N is an integer greater than or equal to 1, and the analog beam meets a first preset condition. The network device receives a measurement result from the terminal device. The measurement result is the signal quality of the first signal. According to the interference measurement method and the apparatus provided in this application, measurement overheads can be reduced.

Abstract: This application provides a method for adjusting a half-power angle of an antenna, to adjust a maximum half-power angle or a maximum beam gain of an individual transceiver channel. The method includes: first determining that M antenna elements in N antenna elements connected to a first transceiver channel of an access network device need to be turned on or off, where N>M≥1, and both N and M are integers, that is, a quantity of antenna elements driven by the first transceiver channel needs to be adjusted; and then sending first indication information to the access network device, where the first indication information is used to indicate to turn on or off the M antenna elements.

Abstract: A CSI-RS transmission method and a network device are provided, to resolve a technical problem that very large pilot resource overheads are occupied for sending CSI-RSs, and reduce pilot transmission resources occupied for sending CSI-RSs, to reduce pilot transmission overheads. The method includes: determining, by a network device, that at least two of M quantities of antenna ports respectively used by M radio remote units RRUs for sending a CSI-RS to same user equipment are not equal, and instructing the M RRUs to send P CSI-RSs on N resource elements, where at least one of the N resource elements carries content of at least two of the P CSI-RSs, the P CSI-RSs are CSI-RSs respectively sent by P RRUs in the M RRUs, M is an integer greater than or equal to 2, P is an integer less than or equal to M, and N is a positive integer.
