Abstract

The embodiment of the application provides a data transmission method of a wireless local area network and equipment. The data transmission method is characterized in that a terminal sends a first data frame to an access device, wherein the first data frame contains indication information and uplink data and the indication information is used for indicating power saving polling and uplink data transmission; and the terminal receives a second data frame sent by the access device based on the first data frame, wherein the second data frame contains response information of the power saving polling indicated by the indication information. Because the power saving polling is indicated in the first data frame carrying uplink data, the uplink data can be sent and downlink data from the access device can be inquired or required simultaneously, thereby improving the data transmission efficiency.

Description

technical field [0001] The present application relates to communication technology, and in particular to a data transmission method and device of a wireless local area network (Wireless Local Area Network, WLAN). Background technique [0002] In a wireless local area network (Wireless Local Area Network, WLAN), when the terminal is in the power saving (Power Save, PS) state, the terminal can temporarily send uplink data to the access device, or it can also send PS polling (PS-Poll) frame to query or request downlink data from the access device. For example, in a wireless compatibility certification (Wireless Fidelity, WIFI) network, a WIFI station (Station, STA) can temporarily send uplink data to a WIFI access point (Access Point, AP), or it can also inquire or request information from the AP. downlink data. [0003] However, the data transmission efficiency of the prior art is low. Contents of the invention [0004] Various aspects of the present application provide a...
