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 provide a power control method, a communication apparatus, and a communication system. The method includes: determining whether a first condition is met, where the first condition includes that a time-frequency resource for sending a first beam and a time-frequency resource for sending a second beam overlap, a ratio of interference of the first beam to the second beam to noise floor of a receiver is greater than a first threshold, and a ratio of interference of the second beam to the first beam to the noise floor of the receiver is greater than the first threshold; and reducing transmit power of the first beam and transmit power of the second beam when the first condition is met.

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.
