Abstract: Embodiments of the invention provide a contention method. The contention method includes: receiving, by an access point, an uplink frame transmitted by a station; transmitting, by the access point, a frame responding to the uplink frame. The frame responding to the uplink frame is used to acknowledge the uplink frame and trigger the station to enter the next channel contention period. The contention method can acknowledge the uplink frame and trigger the station to enter the next channel contention period.

Abstract: 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.

Abstract: A method includes determining, by a first access point, a working mode of a second access point, where a coverage area of the first access point overlaps a coverage area of the second access point, and where the working mode includes a non-coordinated scheduling mode, a coordinated scheduling mode, a contention mode, or an in-slot contention ISC mode. The method further includes initiating, by the first access point, a working mode switching procedure when it is determined that the working mode of the second access point is the non-coordinated scheduling mode, where the working mode switching procedure is used to switch the working mode of the second access point to the contention mode or the ISC mode.

Abstract: Disclosed are methods and devices for data transmission in a wireless local area network. According to the embodiments of the present application, through transmitting by a terminal a first data frame to an access device, where the first data frame includes indication information and uplink data and the indication information is used to indicate a power save poll and uplink data transmission, the terminal can receive a second data frame which is transmitted by the access device according to the first data frame, where the second data frame includes response information of the power save poll indicated by the indication information. Since the first data frame carrying the uplink data indicates the power save poll simultaneously, downlink data from the access device can be inquired or requested at the same time of transmitting the uplink data, so that data transmission efficiency is improved.
