摘要： Embodiments of this application provide a service data transmission method, an access point, and a station. The method includes: receiving, by a station, a control frame, where the control frame includes control information; contending for a resource based on the control information; and sending first-type service data of the station to an access point on the resource obtained by contention, where the control information is used to instruct the station to contend for the resource used to transmit the first-type service data. In the embodiments of this application, the access point triggers the station to perform a procedure of reporting uplink first-type service data, and this can improve transmission efficiency of service data.

摘要： Embodiments of the present invention provide a method, an access point, and a station for establishing an association in a WLAN. The method includes: sending an association message to a group of stations STAs including a plurality of STAs in the wireless local area network WLAN; sending a first notification to the group of STAs, where the first notification carries identifier information of each STA and information about a scheduling sequence for each STA; and receiving response messages sequentially sent, according to the scheduling sequence in the first notification, in response to the association message by the group of STAs. Thereby reducing the number of channel contentions, accelerating the process of associating the STAs with the AP, and ensuring that a STA used for a key application can establish an association with the AP quickly.

摘要： Embodiments provide a signal transmission method and apparatus. The method includes: modulating, by using a phase-shift keying PSK scheme with rotation of a first angle, at least a part of pilot information carried in at least one signaling symbol in a signaling field of a data packet, to obtain modulated pilot information; and sending, to a receive end, a data packet that carries the modulated pilot information. A modulation scheme different from a conventional modulation scheme is used in the embodiments to modulate pilot information carried in a signaling symbol in a signaling field of a data packet, so that a data packet format corresponding to the modulation scheme can be effectively detected at a receive end.
