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: 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: Embodiments of this application disclose a communication apparatus. The communication apparatus may include a first transceiver, a second transceiver, and a power amplifier. The first transceiver and the second transceiver may be separately connected to the power amplifier. In this way, when it is determined that a network load is relatively low, any transceiver in the communication apparatus may be turned off. Because the turned-off transceiver no longer continues to generate power consumption, power consumption of the entire communication apparatus is reduced, to achieve an energy saving effect. In addition, when an electronic component in the communication apparatus is turned off, the power amplifier may not be turned off, and the power amplifier may still receive a corresponding radio frequency signal from a transceiver that is not turned off, to perform power amplification and send a corresponding radio frequency signal.

Abstract: Embodiments of this application disclose a cross-standard scheduling method and a base station, used for unified scheduling of UEs in different standards by using a unified scheduler, to achieve space division multiplexing of a spectrum resource, where different standards may share the spectrum resource. A unified scheduler is disposed in the base station in the embodiments of this application. The method and the base station may obtain downlink channel information of UEs operating using different standards and in overlapping coverage range. The method and the base station may determine a scheduling result using the unified scheduler based on the obtained downlink channel information of the UEs. The method and the base station may schedule the UEs based on the scheduling result.
