Abstract: The present disclosure relates to transmit power control methods and apparatuses. In one example method, a network device determines a transmit power threshold corresponding to a spatial grid. The network device schedules a resource block (RB) or a carrier of one or more terminal devices corresponding to the spatial grid to control a transmit power corresponding to the spatial grid to be less than or equal to the transmit power threshold corresponding to the spatial grid.

Abstract: A network device obtains EMF strength of each grid in a first grid group. The first grid group includes M grids obtained by dividing a signal coverage area of the network device, and M is an integer greater than 1. The network device determines a second grid group based on EMF strength of the M grids. The second grid group includes at least a first grid and a second grid, a coverage area of the first grid is greater than that of the second grid, and EMF strength of the first grid is lower than EMF strength of the second grid. The network device monitors EMF strength of a coverage area of the second grid group based on the second grid group, to adjust the EMF strength of the coverage area of the second grid group.

Abstract: This application provides a communication method and related apparatus. In the communication method, a network device determines a first normalized power at a start moment of an nth period in N periods, and determines a total normalized power expected to be used by a plurality of cells in the nth period. When the total normalized power is greater than the first normalized power, the network device allocates power to each cell based on a preset normalized power of each cell and the first normalized power. This resolves a problem that when a cell power quota at each frequency for a multi-frequency cell is limited, the coverage and network performance of each cell is affected.

Abstract: This application provides an SRS transmission method, an access network device, and a terminal device. The method includes: sending channel sounding reference signal SRS time domain resource indication information to a terminal device, where the SRS time domain resource indication information indicates an SRS time domain resource, and the SRS time domain resource includes at least one of the first symbol to the eighth symbol in a first slot; and receiving an SRS from the terminal device on the SRS time domain resource. In this application, more symbols can be allocated to transmit an SRS, so that more accurate channel estimation can be performed based on the received SRS.

Abstract: A security policy deployment method and apparatus are provided, and the method includes: when a lifecycle state of a virtualized network function VNF changes, generating, by a management network element, a security policy of the VNF, where the security policy of the VNF is used to perform access control on the VNF; and sending, by the management network element, the security policy of the VNF to a control device. The management network element is a network element configured to perform lifecycle management on the VNF. By using the method or apparatus provided in embodiments of this application, the security policy of the VNF can be adjusted in time when the lifecycle state of the VNF changes, thereby greatly reducing a possibility that a bug occurs in the security policy of the VNF because the VNF changes.
