Abstract: The technology described herein relates to 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 a first symbol to an eighth symbol in a first slot. The method further includes receiving an SRS from the terminal device on the SRS time domain resource.

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.

Abstract: This application provides a method for sending a cell downlink fixed resource and a communications apparatus, which are applied to an RRU networking scenario. In the method, a first network device configures a first sending time in which a first cell of the first network device sends a cell downlink fixed resource, and controls the first cell to send the cell downlink fixed resource in the first sending time. The first sending time is different from a sending time in which a neighboring cell of the first cell sends the cell downlink fixed resource, and the first cell and the neighboring cell of the first cell carry a same frequency.

Abstract: The present disclosure relates to equivalent isotropically radiated power (EIRP) control methods and communications apparatus. In one example method, an EIRP threshold of a spatial grid is 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.
