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 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.
