Embodiments of the present invention are described below with reference to the accompanying drawings. The measuring method and the measuring equipment provided by the embodiment of the invention can be applied to a wireless communication system. Referring to fig. 2, an architecture diagram of a wireless communication system according to an embodiment of the present invention is provided. As shown in fig. 2, the wireless communication system may include: a network device 20 and a terminal, denoted UE21, the UE21 may communicate (transmit signaling or transmit data) with the network device 20. In practical application, the connection between the devices may be wireless connection, and for convenience and intuitionistic representation of the connection relationship between the devices, a solid line is used for illustration in fig. 2.

In the embodiment of the invention, the interference between MU-MIMO multi-users is measured by using the CSI-RS resources or the SSB resources in the beam measurement stage, and the measurement resources are not required to be configured independently, so that the expenditure of the NZP CSI-RS used in the current MU-MIMO interference measurement is reduced.

step 401: determining CSI-RS resources or SSB resources of a terminal;

The network equipment transmits the L1-SINR value through DCI or MAC CE indication, so that the network equipment can obtain the measurement of interference between MU-MIMO multi-users, and compared with the current interference measurement scheme of MU-MIMO based on NZP CSI-RS, the time delay of interference measurement between MU-MIMO multi-users can be effectively shortened.
