Patent number: 12047107Abstract: 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.Type: GrantFiled: March 29, 2022Date of Patent: July 23, 2024Assignee: HUAWEI TECHNOLOGIES CO., LTD.Inventors: Xiaojun Zheng, Wei Chen, Jianming Cui
