Abstract

The embodiments of the invention provide a data transmission method and device. The method comprises the following steps: a site STA generating an message frame, wherein message frame is used for determining uplink time frequency resource configuration of the STA by an access point (AP) according to the message frame, the message frame carries the following information: the STA has indication information needed for data transmission, the data type of data sent by the STA and the transmission time length of the data sent by the STA; and the STA sending the message frame to the AP. Therefore, the method and device provided by the embodiments of the invention send data transmission parameters to the AP through the site so that the AP can obtain correlation data transmission parameters of data about to be sent by the site in advance, and the AP can conveniently distribute such correlation confirmation information as time frequency resources and the like for uplink data transmission for the site.

Description

technical field [0001] The present invention relates to the communication field, and more specifically, to a method and device for data transmission in a wireless local area network. Background technique [0002] The next-generation wireless fidelity (English: Wireless-Fidelity, abbreviated: Wi-Fi) technology is also called high-efficiency wireless local area network (English: HighefficiencyWLAN, abbreviated: HEW) technology. The vision proposed by HEW is: Compared with other technologies, it can achieve higher regional throughput and apply to a denser communication environment; improve the effective use of spectrum and improve user experience (English: Quality of Experience, abbreviated: QoE). [0003] In order to improve the efficiency of spectrum utilization, the 802.11ax task group will use Orthogonal Frequency Division Multiple Access (English: Orthogonal Frequency Division Multiple Access, abbreviated: OFDMA) for data transmission. Abbreviation: AP) transmits uplink d...
