Abstract: Embodiments of this application provide an interference processing method and a device, to reduce interference from a cellular network to Wi-Fi signals by reducing uplink transmit power of the cellular network in the field of communications technologies. According to the interference processing method: If a wireless access device determines that there is a Wi-Fi device whose signal status parameter is less than a first threshold in connected Wi-Fi devices, the uplink transmit power of the cellular network is greater than or equal to a second threshold, and a signal status parameter of the cellular network is greater than or equal to a third threshold, and/or determines that a Wi-Fi rate of a Wi-Fi device with a smallest signal status parameter in the connected Wi-Fi devices is less than a fourth threshold, and an air interface throughput of the cellular network is greater than or equal to a fifth threshold, the wireless access device reduces the uplink transmit power of the cellular network, to reduce interference from a cellular signal to a Wi-Fi signal. The embodiments of this application are used for interference processing.

Abstract: This application provides a terminal device and a wireless communications method. When the terminal device is in a dual connectivity network including an LTE link and an NR link, the terminal device determines, based on a service transmission rate related to an actual transmission rate, whether to disconnect the NR link. If the service transmission rate is relatively low, the terminal device disconnects the NR link. If the service transmission rate is relatively high, the terminal device does not disconnect a first link, and uses both the NR link and the LTE link for communication. In this way, power consumption of the terminal device can be effectively reduced without affecting the user experience on transmission rate, the user experience on power consumption is improved, and the user experiences on transmission rate and power consumption are balanced to some extent.

Abstract: This application relates to a network device transmission bandwidth reduction method and related device for reducing a transmission bandwidth of a network device, thereby reducing power consumption and battery life of terminal devices. In one embodiment, a terminal receives transmission bandwidth reduction configuration information sent by a network device, where the transmission bandwidth reduction configuration information includes a set of transmission bandwidth reduction parameters supported by the network device. In response, the terminal sends a target transmission bandwidth reduction coefficient to the network device, where the target transmission bandwidth reduction coefficient is a transmission bandwidth reduction coefficient of a serving cell expected by the terminal. A serving cell is one or more cells that currently provide services for the terminal. In this way, the network device reduces a transmission bandwidth of the serving cell based on the target transmission bandwidth reduction coefficient reported by the terminal.
