Abstract: Embodiments of the present invention provide a method and an apparatus for transmitting channel state information. The method includes: sending a feedback indication message, a high-efficiency long training sequence, and a resource scheduling message, wherein the feedback indication message is used to indicate more than one target STAs that need to feed back channel state information, the high-efficiency long training sequence is used for determining the channel state information by the target STAs, and the first resource scheduling message is used to indicate a communication resource used by the target STAs when the target STAs feed back the channel state information; receiving the channel state information sent by the target STAs by using the communication resource.

Abstract: A method for establishing a communication connection between a station (STA) and an access point (AP). The method includes: receiving, by the AP, request frames sent by N STAs to the AP, and after the AP receives the request frames sent by the N STAs, contending for a channel by the AP and sending one response frame to M STAs, where the response frame includes identifiers of the M STAs and M responses to the M STAs. Each of the identifiers of the M STAs corresponds to one of the M responses, wherein 2≦M≦N.

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: 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.
