Abstract: Embodiments of the present invention provide a nonlinear precoding bit loading method, a transmit end, a receive end, and a system. The method includes: determining, power control factors of multiple preset quantities of bits; obtaining, a first correspondence between the multiple preset quantities of bits and signal to noise ratios without power control; determining, a second correspondence between the multiple preset quantities of bits and signal to noise ratios with power control according to the power control factors and the first correspondence; and after actually measuring a signal to noise ratio with power control on a subcarrier, determining, according to the second correspondence, a preset quantity of bits corresponding to the actually measured signal to noise ratio with power control, using the determined preset quantity of bits as an actual bit loading quantity of the subcarrier, and notifying a transmit end of the actual bit loading quantity.

Abstract: Embodiments of this application disclose a device identification method and a related apparatus, to reduce costs of identifying whether a device that accesses a network is an AP device. The method in the embodiments of this application includes: when a type of the device that accesses the network needs to be identified, obtaining a MAC address of the access device, and obtaining a MAC address of a Wi-Fi hotspot around a network access device; and then comparing the MAC address of the access device with the MAC address of the Wi-Fi hotspot, and determining, if the MAC address of the access device and the MAC address of the Wi-Fi hotspot belong to a same address segment, that the access device is an AP device.
