Abstract: Embodiments of the present invention disclose a state switching method and apparatus. The state switching method includes: receiving, by a first network node, a preset frame sent by a second network node, where the preset frame includes indication information used to indicate an on/off state of a main transceiver and/or a wake up receiver of the first network node immediately, after a specified time point, or within a specified time period; and controlling, by the first network node based on the indication information, to switch an on/off state of the main transceiver and/or the wake up receiver of the first network node. According to the embodiments of the present invention, energy is saved by using a preset frame to indicate an on/off state of a main transceiver and/or a wake up receiver of a network node after a specified time point or within a specified time period.

Abstract: Embodiments of the present invention provide a data transmission method and a station. The method includes: transmitting, by a station, data of a primary access category (AC) of the station within a current transmission opportunity (TXOP), where to-be-transmitted data of the station includes the data of the primary AC and data of at least one secondary AC; after transmission of the data of the primary AC is completed, determining, by the station, whether there is remaining time in the TXOP; and if there is remaining time in the TXOP, transmitting, by the station, the data of the at least one secondary AC within the remaining time. According to the method provided in the embodiments of the present invention, the current TXOP is fully utilized without a channel resource wasted, thereby improving data transmission efficiency of the station.
