Abstract: Embodiments of this application provide an EIRP control method and a communications apparatus. In this solution, an EIRP threshold of a spatial grid may be determined, where the EIRP threshold of the spatial grid is related to a safety distance of the spatial grid; and a plurality of beams are controlled, so that a total EIRP of the plurality of beams in the spatial grid is less than or equal to the EIRP threshold. According to the foregoing solution, a total EIRP of each spatial grid may be controlled, at a granularity of a spatial grid, to not exceed an EIRP threshold of the spatial grid, so that deployment of a MIMO access network device satisfies an EMF strength requirement specified by each country/region.
