Abstract

Provided are a data frame transmission and reception method, station, and access point. A data frame transmission method comprises: an AP generates a downlink data frame, the downlink data frame including an FCS field and at most two address fields, the FCS field or the at most two address fields carrying the receiver address information of the downlink data frames; the AP transmits the downlink data frame to an STA, so that the STA determines according to the receiver address information of the downlink data frame whether to obtain the valid data in the downlink data frame. The technical solution of the present invention reduces the number of address fields included in a data frame, thereby reducing the bit number occupied by the data frame, and reducing the cost of the data frame.

Description

technical field [0001] The present invention relates to wireless communication technology, in particular to a data frame sending and receiving method, station and access point. Background technique [0002] The application scenarios based on the IEEE 802.11ah standard mainly include the following: sensor (Sensors) and meters (meters) scenarios, sensor and meter data backhaul (Backhaul Sensor and Meterdata) scenarios and extended range wireless LAN (Extended range Wi- Fi) scene. Among them, the first application scenario mainly includes specific applications such as smart grid, environmental / agricultural monitoring, industrial process sensors, medical care, home / office automation, and household sensors. [0003] After analysis, it is found that the characteristics of the first application scenario are that the source nodes of the uplink data are all stations (Station, STA), and the destination nodes are all access points (Access Point, AP); similarly, the source nodes of the...
