DATA SENDING METHOD, RECEIVING METHOD AND DEVICE

摘要

Provided are a data sending method, receiving method and device. The sending method comprises: an STA sending characterizing information to an AP, the characterizing information being used for characterizing the maximum transmission time delay allowed by uplink data to be sent by the STA (101); the STA receiving sending time which is designated for the STA and returned by the AP within the maximum transmission time delay allowed by the uplink data to be sent by the STA, the sending time being within the range of the maximum transmission time delay allowed by the uplink data to be sent by the STA (102); and the STA sending the uplink data to the AP within the sending time (103). The technical solution of the present invention solves the problem of data transmission in an emergency application scenario, and guarantees the requirements of emergency data for transmission time delay.
